<abstract>
	<p>Previous research suggests that the concept of <italic>Right-Wing Authoritarianism</italic> (RWA) may be no longer sufficient to explain attraction to contemporary right-wing movements. Using data from two correlational studies in Germany (<italic>N</italic> = 469) and the United States (<italic>N</italic> = 314), we developed the 9-item <italic>Modern Comprehensive F Scale</italic> (MCF-9), integrating all nine facets from the <italic>California F Scale</italic> (<xref ref-type="bibr" rid="r2">Adorno et al., 1950</xref>). Validation criteria included right-wing political and antidemocratic attitudes, antisemitism, xenophobia, and donation preferences. Confirmatory Factor Analysis confirmed the one-dimensionality of MCF-9. The scale showed good internal consistency (ω = .87 in Germany; ω = .90 in the U.S.), and had strong positive associations with RWA, and Social Dominance Orientation (SDO). Notably, MCF-9 accounted for additional variance in all validation criteria (up to 17% in Germany; up to 20% in the U.S.) beyond two established RWA scales, positioning it as valuable contemporary measure. Limitations and implications are discussed.</p>

	<sec sec-type="intro"><title/>
<p>Democracy is under unprecedented pressure, with an increasing number of countries showing democratic backsliding (<xref ref-type="bibr" rid="r36">Gorokhovskaia &amp; Grothe, 2024</xref>). Some researchers even speak of an authoritarian renaissance (<xref ref-type="bibr" rid="r1">Adler et al., 2023</xref>). Authoritarianism is widely discussed in political psychology and sociology and is regarded as underlying anti-democratic, outgroup derogatory, and right-wing attitudes and behavior (<xref ref-type="bibr" rid="r49">Osborne et al., 2023</xref>). Yet, consensus on its definition and measurement remains elusive (<xref ref-type="bibr" rid="r41">Iser, 2006</xref>). The concept of authoritarianism first gained prominence through <italic>The Authoritarian Personality</italic> (<xref ref-type="bibr" rid="r2">Adorno et al., 1950</xref>) and has since been repeatedly re-conceptualized (e.g., <xref ref-type="bibr" rid="r47">Oesterreich, 1996</xref>, <xref ref-type="bibr" rid="r32">Feldman, 2003</xref>; <xref ref-type="bibr" rid="r24">Duckitt, 2001</xref>). The most prominent approaches remain within the framework of <italic>Right-Wing Authoritarianism</italic> (RWA; <xref ref-type="bibr" rid="r5">Altemeyer, 1981</xref>, <xref ref-type="bibr" rid="r6">1988</xref>, <xref ref-type="bibr" rid="r7">1996</xref>), encompassing Authoritarian Aggression, Conventionalism, and Authoritarian Submission. However, the question arises whether modern right-wing movements incorporate elements beyond these three. To provide a broader and contemporary measure of authoritarianism, the present paper introduces the <italic>Modern Comprehensive F</italic> (MCF) <italic>Scale</italic>.</p>
<sec sec-type="other1"><title>The Authoritarian Personality</title>
	<p><italic>The Authoritarian Personality</italic> (<xref ref-type="bibr" rid="r2">TAP</xref>; 1950) was developed by Adorno, Frenkel-Brunswik, Levinson, and Sanford in the aftermath of World War II. Based on their research, they explained the rise of fascism and anti-Semitism in Europe through an individual susceptibility to prejudice and fascism, rooted in early childhood family dynamics and therefore influenced by the child-rearing practices of society.</p>
<p>Combining psychodynamic theory with empirical methods, <xref ref-type="bibr" rid="r2">Adorno et al. (1950)</xref> identified nine interrelated facets: Authoritarian Submission, Conventionalism, Authoritarian Aggression, Anti-Intraception, Superstition and Stereotypy, Power and Toughness, Destructiveness and Cynicism, Projectivity, and Sex (see Appendix A.1 for detailed presentation). They developed the <italic>California Fascism</italic> (F) <italic>Scale</italic>, a highly influential and widely cited measure that, in the course of shifting social and scientific paradigms, faced increasing criticism (e.g., <xref ref-type="bibr" rid="r14">Christie, 1991</xref>).</p>
<p>Key criticisms include the lack of generalizability of the sample (<xref ref-type="bibr" rid="r41">Iser, 2006</xref>), the influence of education levels on results (<xref ref-type="bibr" rid="r35">Funke, 2003</xref>), the issue of inferring personality traits from situation-specific attitudes (<xref ref-type="bibr" rid="r52">Rippl et al., 2000</xref>; <xref ref-type="bibr" rid="r47">Oesterreich, 1996</xref>, <xref ref-type="bibr" rid="r48">2005</xref>), and the lack of interpretive objectivity in the interviews (<xref ref-type="bibr" rid="r45">Martin, 2001</xref>). The most known critique was the response-set problem by <xref ref-type="bibr" rid="r16">Cronbach (1946)</xref>, who noted that ambiguous, uniformly keyed items like those in the F Scale are prone to response bias, an issue also acknowledged by the original authors (<xref ref-type="bibr" rid="r2">Adorno et al., 1950</xref>, p. 161). Also, the scale's external validity was questioned as it relied mainly on correlations with earlier scales (A-S and E; <xref ref-type="bibr" rid="r41">Iser, 2006</xref>), however, its external validity was supported by later research (e.g., <xref ref-type="bibr" rid="r56">Steiner &amp; Fahrenberg, 2000</xref>). <xref ref-type="bibr" rid="r5">Altemeyer (1981)</xref> criticized the unclear distinctions of the subscales. During the cold war, the Berkeley group faced criticism of ideological bias for focusing on authoritarianism on the right and not on the left. This initiated the debate and ongoing controversy on left-wing authoritarianism (e.g., <xref ref-type="bibr" rid="r7">Altemeyer, 1996</xref>; <xref ref-type="bibr" rid="r15">Costello et al., 2022</xref>; <xref ref-type="bibr" rid="r46">Nilsson, 2024</xref>). Finally, the psychodynamic foundation of TAP and its non-falsifiable assumptions were criticized (<xref ref-type="bibr" rid="r5">Altemeyer, 1981</xref>). Later it was argued that the quantitative approach of US social and behavioral sciences had been reductionistic (e.g., <xref ref-type="bibr" rid="r57">Stone et al., 1993</xref>; <xref ref-type="bibr" rid="r44">Lederer &amp; Schmidt, 1995</xref>; <xref ref-type="bibr" rid="r35">Funke, 2003</xref>; <xref ref-type="bibr" rid="r3">Aho, 2020</xref>; <xref ref-type="bibr" rid="r38">Henkelmann et al., 2020</xref>).</p></sec>
<sec sec-type="other2"><title>RWA: Critiques and Developments</title>
<p>With the changing zeitgeist, the psychodynamic concept of TAP gave way to cognitive-psychological approaches (see <xref ref-type="bibr" rid="r35">Funke, 2003</xref>). <xref ref-type="bibr" rid="r5">Altemeyer (1981</xref>, <xref ref-type="bibr" rid="r6">1988</xref>, <xref ref-type="bibr" rid="r7">1996</xref>) adopted a pragmatic, data-driven approach and shortened the scale to the three covarying dimensions of conventionalism, authoritarian aggression, and authoritarian submission, replacing the psychoanalytic foundation with Bandura's social learning theory.</p>
<p>Altemeyer’s RWA scale consists of about 30 counterbalanced items. For a long time, it was considered the standard in measuring authoritarianism (<xref ref-type="bibr" rid="r14">Christie, 1991</xref>; <xref ref-type="bibr" rid="r35">Funke, 2003</xref>), serving as a valuable predictor of right-wing and outgroup derogatory attitudes and behaviors (<xref ref-type="bibr" rid="r26">Duckitt, 2022</xref> provides an overview). Over the last two decades, the general concept of RWA, as well as its operationalization by Altemeyer, has faced growing criticism, including the use of unrepresentative samples, tautological overlap with its criteria (<xref ref-type="bibr" rid="r32">Feldman, 2003</xref>; <xref ref-type="bibr" rid="r48">Oesterreich, 2005</xref>; <xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>; <xref ref-type="bibr" rid="r31">Engelhardt et al., 2023</xref>), limited differentiation from conservatism (<xref ref-type="bibr" rid="r32">Feldman, 2003</xref>; <xref ref-type="bibr" rid="r48">Oesterreich, 2005</xref>), and operationalizing a three-factor construct with a unidimensional scale (<xref ref-type="bibr" rid="r35">Funke, 2003</xref>; <xref ref-type="bibr" rid="r58">Van Hiel et al., 2007</xref>). Overall, Altemeyer's approach has been criticized for prioritizing methodological refinements over theoretical depth (<xref ref-type="bibr" rid="r44">Lederer &amp; Schmidt, 1995</xref>; <xref ref-type="bibr" rid="r38">Henkelmann et al., 2020</xref>).</p>
<p>To address these shortcomings, a wide range of authoritarianism scales has emerged, the acronyms of which are not easy to tell apart: there is the RWA<sup>3</sup>D scale (<xref ref-type="bibr" rid="r35">Funke, 2003</xref>), the <italic>Child Rearing Values</italic> (CRV) scale (<xref ref-type="bibr" rid="r33">Feldman &amp; Stenner, 1997</xref>), the <italic>Authoritarian Submission Conventionalism</italic> (ASC) scale (<xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>), the Social Conformity-Autonomy Beliefs (SCA) Scale (<xref ref-type="bibr" rid="r32">Feldman, 2003</xref>), the <italic>Authoritarianism-Conservatism-Traditionalism</italic> (ACT) scale (<xref ref-type="bibr" rid="r27">Duckitt et al., 2010</xref>), the <italic>Very Short Authoritarianism</italic> (VSA) scale (<xref ref-type="bibr" rid="r11">Bizumic &amp; Duckitt, 2018</xref>), the <italic>Kurzskala Autoritarismus</italic> (Short Authoritarianism Scale; KSA; <xref ref-type="bibr" rid="r10">Beierlein et al., 2014</xref>), the <italic>Aggression-Submission</italic> (AS) scale (<xref ref-type="bibr" rid="r58">Van Hiel et al., 2007</xref>), and the <italic>Group Authoritarianism</italic> (GA) scale (<xref ref-type="bibr" rid="r55">Stellmacher &amp; Petzel, 2005</xref>), among others. As noted by <xref ref-type="bibr" rid="r29">Dunwoody and Funke (2016)</xref>, most of these scales capture “Altemeyer’s big Three” (p. 574). While addressing major problems, none is free from all criticisms (Appendix A.2).</p>
	<p>There are other alternative theoretical approaches alongside RWA: Oesterreich (e.g., <xref ref-type="bibr" rid="r47">1996</xref>, <xref ref-type="bibr" rid="r48">2005</xref>) described the authoritarian reaction as a coping strategy in response to insecurity and overwhelm. <xref ref-type="bibr" rid="r32">Feldman (2003)</xref> situated authoritarianism within the social conformity-autonomy dimension, identifying the tension between these poles as the key dynamic behind authoritarianism, with prejudicial behavior as a consequence of threats to social norms. <xref ref-type="bibr" rid="r24">Duckitt (2001</xref>, <xref ref-type="bibr" rid="r25">2006</xref>), in his Dual Process Motivational Model (DPM), conceptualized authoritarianism as ideological attitudes rooted in a view of the world as dangerous and unpredictable, with perceived threats to social order activating a security motivation and identification with norms and traditions, ultimately fostering prejudice. These approaches highlight the psychological complexity of authoritarianism, indicating gaps in RWA. We argue that contemporary right-wing populist movements incorporate elements that challenge explanation through classic RWA alone:</p>
<sec><title>The Missing Emotional Component</title>
	<p>Classical RWA emphasizes cognitive rather than emotional components, failing to explain why right-wing leaders hold such emotional appeal for people (<xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>). Alternative approaches, in fact also mentioned but not further elaborated by <xref ref-type="bibr" rid="r7">Altemeyer (1996</xref>, pp. 40-41, p. 100), incorporate the role of fear or insecurity with authoritarianism alleviating psychological discomfort, reminiscent of Fromm’s "prosthetic security" (<xref ref-type="bibr" rid="r34">Fromm, 1936</xref>) of authoritarianism. But anxiety alone cannot explain right-wing movements, as it neglects the crucial role of aggression (<xref ref-type="bibr" rid="r5">Altemeyer, 1981</xref>; <xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>) which cannot be reduced to the generalized hostility proposed by Oesterreich (e.g., <xref ref-type="bibr" rid="r48">2005</xref>). The framework of TAP exceeds classical RWA by integrating irrational processes of projection, fear of sensitivity, a pessimistic view of humanity and the world, and a focus on strength and power.</p></sec>
<sec><title>The Non-Contemporaneity of the Norm-Conforming, Submissive Authoritarian</title>
<p>In contrast to RWA’s submissive, norm-conforming concept, an inherent characteristic of modern right-wing movements is that they challenge norms and traditional authority (<xref ref-type="bibr" rid="r61">Vehrkamp &amp; Merkel, 2020</xref>). Examples include opposition to COVID-19 restrictions, climate change denial, and advocacy of socially unaccepted conspiracy theories (<xref ref-type="bibr" rid="r18">Decker &amp; Brähler, 2020</xref>; <xref ref-type="bibr" rid="r9">Amlinger &amp; Nachtwey, 2022</xref>). Rather, they practice selective submission to leaders who emphasize strength over diplomacy (<xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>), such as Putin, Bolsonaro, Xi, or Trump (<xref ref-type="bibr" rid="r51">Rachman, 2022</xref>). This pattern is not new, as historical examples like the Weimar Republic show that authoritarian individuals have often rejected established authorities while embracing strong leaders (<xref ref-type="bibr" rid="r64">Wildt, 2012</xref>). In Germany, however, current right-wing leaders like Alice Weidel do not seem to be fueling this personality cult. Instead, submission appears to shift toward neoliberal values. <xref ref-type="bibr" rid="r17">Decker (2019)</xref> describes a secondary authoritarianism, with Germany’s economic strength replacing traditional authority. In a qualitative approach, <xref ref-type="bibr" rid="r9">Amlinger and Nachtwey (2022)</xref>, building on Adorno’s typology, identify a libertarian authoritarianism and describe individuals frustrated by unmet neoliberal promises rejecting authorities and submitting to their own freedom. Drawing on these observations, we argue for a broader understanding of authoritarianism, as originally conceptualized in the TAP.</p></sec>
<sec><title>Additional Explanatory Value of the California F Scale’s Omitted Facets</title>
	<p>We are not the first to note that TAP holds significant value and appears even more relevant in light of current developments (e.g., <xref ref-type="bibr" rid="r18">Decker &amp; Brähler, 2020</xref>; <xref ref-type="bibr" rid="r38">Henkelmann et al., 2020</xref>; <xref ref-type="bibr" rid="r42">Jost, 2021</xref>; <xref ref-type="bibr" rid="r22">Dilling et al., 2024</xref>). In terms of projectivity and superstition, <xref ref-type="bibr" rid="r18">Decker and Brähler (2020)</xref> propose a two-factor model in which projectivity, an overarching term for conspiracy mentality and superstition, and RWA together form the authoritarian syndrome. With regard to Anti-Intraception, literature shows correlations of RWA and low emotional competencies (<xref ref-type="bibr" rid="r59">Van Hiel et al., 2019</xref>), creativity (<xref ref-type="bibr" rid="r53">Rubinstein, 2003</xref>), and openness to experience (<xref ref-type="bibr" rid="r50">Perry &amp; Sibley, 2012</xref>). Its association with sexism and rigid gender roles (<xref ref-type="bibr" rid="r28">Duckitt &amp; Sibley, 2017</xref>) is reminiscent of the Sex facet. Among contemporary movements, one can observe hypermasculine self-presentation and aggression (<xref ref-type="bibr" rid="r51">Rachman, 2022</xref>), reminiscent of Power and Toughness, and a fear of status loss (<xref ref-type="bibr" rid="r62">Walther &amp; Isemann, 2019</xref>), group-based misanthropy (<xref ref-type="bibr" rid="r66">Zick et al., 2016</xref>), and violent and depressive tendencies (<xref ref-type="bibr" rid="r18">Decker &amp; Brähler, 2020</xref>), reminding of Destructiveness and Cynicism.</p></sec></sec>
<sec sec-type="other3"><title>The Present Research</title>
<p>The aim of our research was to construct and validate a <italic>Modern Comprehensive F Scale</italic> (MCF-9) in Germany and the U.S. These countries are historically linked to TAP, and are now modern democracies facing polarization and right-wing radicalization (<xref ref-type="bibr" rid="r13">Caiani et al., 2012</xref>). In terms of convergent validity, we expected positive correlations between MCF-9 and RWA. For criterion validity, we anticipated positive associations with sympathy for the right-wing extremist party AfD in Germany, and a preference for right-wing politicians in the U.S. In both countries, we expected positive associations with right-wing self-placement, (anti-)democratic attitudes, xenophobia, antisemitism, and donation preferences for charities with a right-wing leaning. Finally, we assumed incremental validity of MCF-9 beyond RWA in all dependent variables. With regard to broader debates, exploratory analyses examined the relationship with conspiracy mentality (e.g., <xref ref-type="bibr" rid="r21">Dilling et al., 2023</xref>), Social Dominance Orientation (SDO; e.g., <xref ref-type="bibr" rid="r26">Duckitt, 2022</xref>), and far-left attitudes (e.g., <xref ref-type="bibr" rid="r7">Altemeyer, 1996</xref>).</p></sec>
<sec sec-type="other4"><title>Generating the Item Pool</title>
	<p>A pool of 97 items was created by members of the Department of Psychology of the University of Bonn through a rational construction process grounded in the theoretical concepts of <xref ref-type="bibr" rid="r2">Adorno et al. (1950)</xref>. We drew on original items from Altemeyer (e.g., 1996), <xref ref-type="bibr" rid="r2">Adorno et al. (1950)</xref>, and our previous work (<xref ref-type="bibr" rid="r39">Heidemeyer et al., 2025</xref>), but also developed new items, ensuring through extensive discussions that the original conception was preserved (Appendix A.3). To ensure content validity, we consulted 14 researchers specialized in political psychology to provide feedback in a blind pretest that we evaluated using quantitative and qualitative assessments. After excluding poorly rated and ambiguous items, the final item pool consisted of 84 items.</p></sec></sec>
<sec sec-type="methods"><title>Method</title>
<p>Data were analyzed using several statistical methods, including confirmatory factor analysis (CFA), measurement invariance testing, and both correlational and regression analyses. Both studies were introduced as surveys on sociopolitical attitudes. Data were collected in summer 2023 (Germany) and summer 2024 (U.S.) on the platform SoSci Survey via social media. We targeted social media groups that we identified as right-wing, in order to achieve an oversampling of right-wing individuals. Additionally, we ran paid Facebook ads featuring a flyer designed to appeal to politically dissatisfied individuals. Participation was voluntary, without monetary compensation, but incentivized through a raffle for online store vouchers; German psychology students could receive course credit. Participants had to meet the minimum voting age (16 in Germany, 18 in the U.S.) and reside in their country. Informed consent was obtained beforehand.</p>
<sec><title>Samples</title>
<sec><title>German Sample</title>
<p>The original German sample included 745 participants. As preregistered, exclusions were made for incomplete questionnaires (<italic>n</italic> = 234), self-reported poor data quality (n = 38), short response times (&lt; 300 seconds; <italic>n</italic> = 1), and multivariate outliers indicating careless responding (Mahalanobis distance &gt; 30; <italic>n</italic> = 1), leaving 469 participants. Of these, 47.1% were female, and 1.3% gender-diverse. The mean age was 53 years (<italic>SD</italic> = 17.64; range 16–88). Educational levels included 36% with secondary school <italic>(</italic>Mittlere Reife<italic>)</italic> or lower, 24.5% with Abitur, and 39.4% holding at least a bachelor's degree. A migrant background was reported by 9.4%.</p></sec>
<sec><title>U.S. Sample</title>
<p>The initial U.S. sample included 615 participants. After exclusions for incomplete data (<italic>n</italic> = 263), low data quality (<italic>n</italic> = 9), careless responding (Mahalanobis distance &gt; 42; <italic>n</italic> = 15), and fictitious politicians (<italic>n</italic> = 25), 314 participants remained. Of these, 39.8% were female, and 3.2% gender-diverse. The mean age was 63 years (<italic>SD</italic> = 18.34; range 18–93). Educational levels included 29.3% with a high school diploma or lower and 70.7% holding at least a college degree. The majority identified as White/Caucasian (86.3%).</p></sec></sec>
<sec><title>Instruments</title>
<p>All measures were assessed on five-point Likert scales ranging from 1 = <italic>strongly disagree/no sympathy</italic> to 5 = <italic>strongly agree/strong sympathy.</italic></p>
<sec><title>Authoritarianism</title>
<p>We used MCF-9 (<xref ref-type="table" rid="t1">Table 1</xref>) and two established RWA scales. In Germany, we applied the 9-item KSA-3 scale (<italic>Kurzskala Autoritarismus</italic>; <xref ref-type="bibr" rid="r10">Beierlein et al., 2014</xref>), a three-dimensional measure used in large representative studies. For the U.S., we employed the three-dimensional 15-item ASC scale (<italic>Aggression-Submission-Conventionalism</italic>; <xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>), extensively used and validated in the US context.</p>

<sec><title>Right-Wing Policies</title>
<p>In Germany, we assessed participants' sympathy for the six major parties represented in the German parliament: the conservative Christian Union (CDU), the social democrats (SPD), the liberal party (FDP), the left-wing party (DIE LINKE), the green party (Bündnis 90/die Grünen), and the right-wing populist party (AfD). In the U.S., we assessed participants' agreement with the positions of six prominent politicians<xref ref-type="fn" rid="fn1"><sup>1</sup></xref><fn id="fn1"><label>1</label>
<p>The index provides a simplified measure of directional political preference that does not reflect all ideological nuances. For instance, a person with a right-wing or populist orientation may also express sympathy for Bernie Sanders due to shared populist rhetoric, which could slightly lower their score. However, the overall directional tendency remains robust.</p></fn>: ranging from far-right Donald Trump and Marjorie Taylor Greene, and more moderate conservative Mitt Romney. Left-wing progressive positions were represented by Alexandria Ocasio-Cortez and Ilhan Omar, and Bernie Sanders. In both countries, a single item queried political orientation on a scale from 1 (left) to 5 (right). German participants filled out a 5-item questionnaire on Democratic attitudes (<xref ref-type="bibr" rid="r65">Küpper, 2021</xref>); U.S. Participants filled out a 17-item questionnaire on far-right attitudes (<xref ref-type="bibr" rid="r63">Walther et al., 2024</xref>).</p></sec>
<sec><title>Xenophobia and Antisemitism</title>
<p>In Germany, we employed the 18-item <italic>Questionnaire on Right-Wing Extremist Attitudes – Leipzig Form</italic> (FR-LF; <xref ref-type="bibr" rid="r19">Decker et al., 2013</xref>; <xref ref-type="bibr" rid="r37">Heller et al., 2020</xref>), which captures xenophobia and antisemitism as two dimensions of right-wing extremism, each measured by three items. In the U.S., the 5-item <italic>Fear-Based Xenophobia</italic> scale (<xref ref-type="bibr" rid="r60">van der Veer et al., 2013</xref>) and the 12-item <italic>Generalized Antisemitism</italic> Scale (<xref ref-type="bibr" rid="r4">Allington et al., 2022</xref>) were used.</p></sec>
<sec><title>Donation Behavior</title>
<p>Participants selected one of three organizations for a 50-euro/50-dollar donation, with each option reflecting a specific political orientation (<xref ref-type="bibr" rid="r54">Skopp, 2021</xref>; <xref ref-type="bibr" rid="r39">Heidemeyer et al., 2025</xref>). The left-leaning option was the <italic>National Association for the Advancement of Colored People</italic> (NAACP) and <italic>Sea Watch e.V.</italic> The neutral option was the <italic>American Red Cross</italic> (ARC) and <italic>SOS Kinderdörfer</italic> (SOS Children’s village).

<sec><title>Scale Construction</title>
<p>The item pool demonstrated excellent internal consistencies (Germany: ω = .97; USA: ω = .96). Following the unidimensional approach indicated by previous findings (<xref ref-type="bibr" rid="r39">Heidemeyer et al., 2025</xref>) and exploratory factor analyses (Appendix B.5), items were reduced iteratively based on item analysis, theoretical relevance, and linguistic clarity. We prioritized items with high discriminative powers, high variances, and moderate item difficulties, but we retained some low and high difficulty items to represent the full trait continuum.</p>
<p>In the German study, we first developed a unidimensional 27-item prototype (MCF-27, validation in Appendix B.2), with each of the nine facets represented by three items. To prepare for the U.S. study, this version, along with additional reserve items (totaling 35 items), was translated into English using formal forward-backward translation (OSF) by two native speakers, both researchers with expertise in political science and psychology. Based on data from the U.S. study, the scale was further refined through iterative item analysis, involving a trade-off between psychometric properties, the retention of as many reverse-keyed items as possible, and completeness. Item difficulty and item discrimination are important psychometric indicators in scale construction. Item difficulty refers to how easy or hard an item is for the target population; Item discrimination reflects the correlation between an item's score and the total score of the scale, indicating how well the item differentiates between participants with different levels of the underlying construct. This process resulted in the final 9-item MCF-9 (<xref ref-type="table" rid="t1">Table 1</xref>) with strong internal consistencies (ω = .87 in Germany; ω = .90 in the U.S.).</p></sec>
<sec><title>Descriptive Analyses</title>
<p>Reflecting our recruitment strategy, the German sample showed the AfD as the most popular party (<italic>M</italic> = 2.44, <italic>SD</italic> = 1.67), with 32.2% expressing strong sympathy (scores &gt; 3). On a left-right spectrum, 23.9% identified as right-leaning (scores &gt; 3). The majority chose to donate to <italic>SOS Children’s Villages</italic> (59.1%), followed by <italic>Sea-Watch</italic> e.V. (22.2%) and the <italic>German War Graves Commission</italic> (18.8%). The U.S. sample self-positioned center to right (<italic>M</italic> = 3.02, <italic>SD</italic> = 1.33), with no clear preference for the Republican (<italic>M</italic> = 2.71, <italic>SD</italic> = 1.54) or Democratic (<italic>M</italic> = 2.72, <italic>SD</italic> = 1.52) parties. Sanders was the most popular politician (<italic>M</italic> = 2.87, <italic>SD</italic> = 1.61), and Greene the least popular (<italic>M</italic> = 2.21, <italic>SD</italic> = 1.47).

Maximum likelihood estimation was used to assess model fit, with bootstrapping (1,000 samples) addressing non-normality detected by the Doornik-Hansen test (<xref ref-type="bibr" rid="r23">Doornik &amp; Hansen, 2008</xref>; Germany: χ<sup>2</sup>(18) = 311.56, <italic>p</italic> &lt; .001; USA: χ<sup>2</sup>(18) = 172.38, <italic>p</italic> &lt; .001). The χ<sup>2</sup> test indicated significant misfit (Germany: χ<sup>2</sup>(27) = 87.43, <italic>p</italic> &lt; .001; USA: χ<sup>2</sup>(27) = 83.30, <italic>p</italic> &lt; .001), reflecting the test's sensitivity to large sample sizes. Alternative fit indices provide a more accurate evaluation. For Germany, the CFI = .96, TLI = .94, SRMR = .04, and RMSEA = .07, 90% CI [0.05, 0.09], <italic>p</italic>-close = .025 indicated satisfactory fit. Standardized factor loadings ranged from .52 to .78, all significant (<italic>p</italic> &lt; .001), explaining 27–61% of variance across facets. For the USA, the CFI was .96, TLI = .94, SRMR = .05, and RMSEA = .08, 90% CI [0.06, 0.10], <italic>p</italic>-close = .005. Loadings ranged from .55 to .89 (<italic>p</italic> &lt; .001), explaining 30–80% of variance. Bootstrap analyses confirmed parameter stability, with no improper solutions or Heywood cases.</p>

<p>Tests for measurement invariance between the two countries using multigroup CFA showed an acceptable fit for the configural model and for the metric model, but not for the scalar model. Overall, these results support the comparability of the scale across both samples, however suggesting that mean comparisons between the countries may be problematic. An approximate invariance test using the alignment method indicated that approximate measurement invariance could be assumed (see Appendix A.8 for details).</p></sec>

<sec><title>Regression Analyses</title>
<p>We conducted hierarchical multiple regression analyses, introducing the three RWA subscales separately into the analyses considering the unique variance contributed by each facet. Including age and gender as controls did not alter the results (Appendix A.3.1).</p>
<p>MCF-9 was a strong predictor across all dependent variables, accounting for significant amounts of variance in right-wing politics (Germany: 54%, USA: 77%), self-positioning (Germany: 39%, USA: 57%), xenophobia (Germany: 66%, USA: 81%), and (anti-)democratic attitudes (Germany: 29%, USA: 81%). For antisemitism, it explained 23% in Germany and 3% in the USA, with RWA and MCF-9 combined accounting for 17% in the U.S. The scale demonstrated incremental validity, outperforming the KSA and ASC scales (VIF<sub>Germany</sub> = 2.09, VIF<sub>USA</sub>= 2.00) by accounting for additional variance in right-wing preferences (Germany: 17%, USA: 14%), self-positioning (8%), xenophobia (Germany: 11%, USA: 20%), antisemitism (Germany: 4%, USA: 14%), and (anti-)democratic attitudes (Germany: 10%, USA: 15%). Notably, MCF-9 demonstrated incremental validity even beyond RWA and conspiracy mentality combined (Appendix A.6).</p></sec></sec>
<sec sec-type="discussion"><title>Discussion</title>
<p>This paper has introduced the <italic>Modern Comprehensive F Scale</italic> (MCF-9), a 9-item measure shorter than many modern RWA scales, incorporating six additional components beyond RWA, and accounting for additional variance in predicting right-wing political and outgroup derogatory attitudes—supporting the view that authoritarianism extends beyond current measures.</p>
<sec><title>The Psychometric Quality of MCF-9</title>
<p>With standardized administration ensuring consistent data collection, and a numerical scoring process minimizing subjective interpretation and enhancing comparability, MCF-9 meets the criteria for implementation, scoring, and interpretational objectivity. In terms of reliability, the very good internal consistency is remarkable for a heterogeneous and short scale like MCF-9. Content validity was assessed through a rational scale construction process and confirmed by a blind expert rating. In terms of construct validity, our scale was associated with a range of criteria closely aligned in the nomological network (e.g., RWA, SDO), and negatively associated with constructs considered distant (e.g., democratic or left-wing attitudes). However, we did find a small, but significant negative association with the submission facet in the U.S., possibly reflecting our efforts to modernize the facet (Appendix A.3) and indicating that our scale captures more rebellious forms of authoritarianism. Furthermore, our results indicate that, like RWA, MCF is specific to the right-wing political spectrum. Regarding factor validity, an unidimensional model was confirmed with reasonable fit indices and substantial factor loadings. Evidence for MCF’s concurrent validity (criterion validity) showed it to be a significant predictor of right-wing, (anti-)democratic, and outgroup derogatory attitudes, with <italic>R</italic><sup>2</sup> values reaching up to .66 in Germany and .81 in the US.</p>
<p>Most importantly, MCF-9 demonstrated substantial incremental validity to two established RWA scales (up to 17%–20%). This result confirms that the MCF-scale is a psychometrically sound and useful measure of authoritarianism.</p></sec>
<sec><title>Limitations and Future Implications</title>
<p>The inclusion of conservatism within the conventionalist facet may invite criticism. However, rather than interpreting conservatism as an inflation, we argue that it represents an inherent and meaningful aspect of authoritarianism (see <xref ref-type="bibr" rid="r2">Adorno et al., 1950</xref>, pp. 658-675). This aligns with <xref ref-type="bibr" rid="r27">Duckitt et al. (2010)</xref>, who also integrate conservatism into their concept, but we argue, like <xref ref-type="bibr" rid="r29">Dunwoody and Funke (2016)</xref>, that it relates more to conventionalism than submission.</p>
<p>Reverse-keyed items demonstrated satisfactory discrimination, minimizing the trade-off between reliability and balance. With one-third of the items balanced, the scale addresses a key criticism of the <italic>California F Scale</italic> (e.g., <xref ref-type="bibr" rid="r14">Christie, 1991</xref>). However, it can be criticized that we did not develop psychometric 'twins' or systematically compare reverse and non-reverse items across populations (<xref ref-type="bibr" rid="r5">Altemeyer, 1981</xref>; <xref ref-type="bibr" rid="r47">Oesterreich, 1996</xref>, <xref ref-type="bibr" rid="r48">2005</xref>).</p>
<p>With regard to the implementation process, we acknowledge that sequence effects cannot be entirely ruled out, as the political attitude questions preceded the donation decision, potentially influencing responses toward consistency with prior attitudes, though we expect this effect to be small. Furthermore, as we aimed to examine relations between variables rather than make statements about populations, our emphasis was not on representative samples but on ensuring sufficient variance in the relevant characteristics for more accurate detection of these relationships. While oversampling mitigated representativeness issues, left-wing organizations and politicians remained popular. For generalizability, MCF-9 should be tested in large-scale, representative studies. As a further limitation, validation using external criteria through correlations and regressions is not corrected for measurement error. To address this limitation, we also conducted structural equation modeling (SEM) analyses, as detailed in Appendix A.7. Our unidimensional approach may also be subject to criticism. Multidimensional scales like the KSA-3 (<xref ref-type="bibr" rid="r10">Beierlein et al., 2014</xref>) and the ASC scale (<xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>) allow for a more targeted assessment. Furthermore, previous research has demonstrated that multidimensional RWA measures provide greater explanatory power than unidimensional ones (e.g., <xref ref-type="bibr" rid="r27">Duckitt et al., 2010</xref>; <xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>). Although our unidimensional MCF-9 might forgo these benefits, its incremental validity over two multidimensional scales suggests that this concern is not critical. Still, future research could try to construct a multidimensional MCF scale with additional items (Appendix B.5), structured either as a second-order or general factor model. We presented an unidimensional factor structure because (1) a multidimensional model lacked conceptual clarity, and (2) it fitted our data well. This aligns with notions that a nine-dimensional solution lacks coherence (<xref ref-type="bibr" rid="r41">Iser, 2006</xref>) and Adorno et al.’s concept of an “over-all syndrome” (p. 751). The holistic, unidimensional approach allowed us to create a concise and economical instrument, that is suitable for large-scale surveys due to its brevity, while enabling the measurement of the construct's complexity and breadth.</p>
<p>Future research could address our scale’s relationship to RWA, SDO and <xref ref-type="bibr" rid="r24">Duckitt’s (2001</xref>, <xref ref-type="bibr" rid="r25">2006</xref>) DPM. While Duckitt describes RWA and SDO as distinct constructs, <xref ref-type="bibr" rid="r8">Altemeyer (1998)</xref> views them as two sides of authoritarianism: authoritarian dominance (SDO) and authoritarian aggression (RWA). The SDO scale mainly reflects the rejection of group equality and endorsement of group dominance (<xref ref-type="bibr" rid="r40">Ho et al., 2015</xref>), also captured in Power and Toughness. Given the high correlations observed, MCF-9 may be the broader core underlying RWA and SDO, fitting its equally strong correlations.</p>
<p>Moreover, we expect a nomological proximity between MCF-9 dimensions and contemporary concepts of authoritarianism (<xref ref-type="bibr" rid="r9">Amlinger &amp; Nachtwey, 2022</xref>; <xref ref-type="bibr" rid="r18">Decker &amp; Brähler, 2020</xref>), requiring further empirical investigation.</p>
<p>A critical goal is also to explore MCF’s variability and malleability over time. Critical Theory is not abstract research, but a social critique of the conditions that foster authoritarian dynamics (<xref ref-type="bibr" rid="r20">Decker et al., 2024</xref>). These dynamics can be amplified by the uncertainties in competitive neoliberal societies (<xref ref-type="bibr" rid="r48">Oesterreich, 2005</xref>; <xref ref-type="bibr" rid="r18">Decker &amp; Brähler, 2020</xref>) and relative deprivation, and may possibly be mitigated through equal conditions and participation (<xref ref-type="bibr" rid="r22">Dilling et al., 2024</xref>; <xref ref-type="bibr" rid="r63">Walther et al., 2024</xref>).</p></sec>
<sec><title>The Added Value of the Modern Comprehensive F Scale</title>
<p>The <italic>Authoritarian Personality</italic> was published over 75 years ago. After numerous publications and theoretical approaches, the question about the core, explaining factor (<xref ref-type="bibr" rid="r35">Funke, 2003</xref>) of authoritarianism remains unresolved. Theories consistently highlight the role of fear, overwhelm, and threat. A negative view on humanity and the world may foster these feelings, and projection, emphasis on power and toughness, belief in conspiracies and superstitions, as well as anti-intraception may emerge as coping strategies. This study aimed to deepen the understanding of these underlying dynamics, addressing the emotional appeal of right-wing movements (<xref ref-type="bibr" rid="r29">Dunwoody &amp; Funke, 2016</xref>), and providing a new measure for future research to encounter them.</p>
