The Radicalism-Conservatism Scale<\/strong> (RCS), developed by psychometrician Andrew L. Comrey and John A. Newmeyer in 1965, represents a seminal psychometric instrument designed to assess sociopolitical ideology along a unified, multidimensional bipolar continuum. Built in an era marked by intense political realignment, the Cold War, and civil rights mobilizations, the RCS operationalized the latent structure underlying ideological self-placement through rigorous factor-analytic methodology. Comprising two parallel 30-item instruments (Form A and Form B), the RCS assesses 13 distinct sociopolitical and moral domains: Religiosity, Pacifism, Welfarism, Anti-unionism, Weak Federal Government (states' rights and free-market capitalism), Moral Censorship, Contraception\/Reproductive Freedom, Racial Tolerance, Severe Treatment of Criminals, Capital Punishment, Service to Country (patriotism and militarism), World Government, and Service to the Individual. Respondents evaluate statements utilizing a 9-point Likert-type response scale ranging from 1 (agree very strongly<\/em>) to 9 (disagree very strongly<\/em>). Extensive psychometric validation demonstrated robust internal consistency across both parallel forms (split-half coefficients and parallel-form correlations routinely exceeding $r = .85$<\/span>), alongside pronounced convergent validity with political party identification, voting behavior, and related psychometric constructs such as Right-Wing Authoritarianism<\/a> and social dominance attitudes. Factor-analytic extraction consistently isolates a dominant second-order super-factor representing generalized Radicalism versus Conservatism, which accounts for substantial shared variance across divergent attitudinal sub-facets. This article provides a comprehensive psychometric review of the RCS, detailing its theoretical heritage, latent construct architecture, empirical validity, reliability metrics, scoring algorithms, and historical impact within political psychology and survey research methodology.<\/p>\n Radicalism-Conservatism Scale, Andrew L. Comrey, Political Ideology, Conservatism, Radicalism, Psychometrics, Factor Analysis, Attitude Measurement, Social Psychology, Parallel Forms Reliability<\/p>\n The Radicalism-Conservatism Scale was formulated and standardized by two prominent researchers at the University of California, Los Angeles<\/a> (UCLA):<\/p>\n The primary purpose of the Radicalism-Conservatism Scale is to provide an empirically grounded, psychometrically standardized measure of individual differences in socio-political and economic ideology. During the mid-twentieth century, the assessment of ideological attitudes was dominated by instruments that either confounded ideological content with psychopathology\u2014such as the California F-Scale developed by Adorno and colleagues (The Authoritarian Personality<\/a>)\u2014or failed to implement rigorous modern factor-analytic controls to guard against item heterogeneity, acquiescence response set, and dimensional instability.<\/p>\n Comrey and Newmeyer designed the RCS to overcome these methodological limitations. Their objective was to ascertain whether heterogeneous socio-political attitudes\u2014ranging from theological beliefs and moral censorship to military foreign policy and welfare state economics\u2014coalesced into a coherent, unitary higher-order dimension of Radicalism-Conservatism, or whether political attitudes operated as orthogonal, independent ideological traits. By crafting two psychometrically parallel forms (Form A and Form B), the authors also intended to furnish researchers with interchangeable batteries suitable for longitudinal investigations, pre-post experimental designs, and split-ballot survey research without introducing item-exposure artifacts.<\/p>\n In applied and research contexts, the RCS has been extensively utilized in political science, organizational behavior, sociology, and social psychology. It enables researchers to:<\/p>\n The central construct measured by the RCS is Radicalism-Conservatism<\/strong>, conceptualized as a bipolar latent continuum of sociopolitical orientation. In Comrey and Newmeyer's framework, Conservatism<\/em> reflects a psychological and behavioral disposition toward the preservation of established institutional orders, deference to traditional religious and moral authority, national sovereignty, punitive legal deterrence, and unrestricted free-enterprise capitalism. Conversely, Radicalism<\/em> (operationally equivalent in modern nomenclature to progressive liberalism or left-wing egalitarianism) denotes an openness to fundamental socio-structural transformation, secularism, individual autonomy in private morality, international cooperation, and state-mediated redistributive social welfare.<\/p>\n To capture this broad construct comprehensively, the RCS systematically incorporates 13 operationalized sub-facets across both parallel forms:<\/p>\n The theoretical architecture of the Radicalism-Conservatism Scale is grounded in the pioneering psychometric tradition of attitude measurement established by L. L. Thurstone (1928), Leonard W. Ferguson (1939), and Hans J. Eysenck (1944, 1954). Thurstone's law of comparative judgment first demonstrated that subjective sociopolitical sentiments could be quantified with mathematical precision along continuous psychological intervals.<\/p>\n Ferguson's structural analysis of primary social attitudes subsequently isolated three fundamental factors: Religionism<\/em>, Humanitarianism<\/em>, and Nationalism<\/em>. However, it was Hans J. Eysenck<\/a> who formalized the two-dimensional model of sociopolitical ideology, identifying two orthogonal axes: Radicalism-Conservatism (R-factor)<\/strong> and Tough-Mindedness versus Tender-Mindedness (T-factor)<\/strong>. Eysenck postulated that the R-factor represents the core content of ideological allegiance\u2014subsuming economic, religious, and political policies\u2014whereas the T-factor captures a stylistic or temperamental dimension governing how rigidly or aggressively those beliefs are held.<\/p>\n Comrey and Newmeyer (1965) synthesized this psychometric lineage while adopting Comrey's refined Factored Homogeneous Item Dimension<\/em> (FHID) methodology. This methodology posits that complex personality and attitudinal super-factors are constituted by stable, intercorrelated clusters of highly specific behaviors and opinions. Rejecting purely psychoanalytic or pathological conceptualizations of conservatism\u2014such as the dynamic ego-defensive hypotheses advanced in The Authoritarian Personality<\/em>\u2014Comrey and Newmeyer framed political ideology as a normative structure of learned social attitudes. According to their theoretical rationale, when diverse social issues are subjected to factor analysis, cognitive and cultural pressures toward ideological consistency (what Philip Converse later termed ideological "constraint") cause specific attitudes to coalesce into a powerful, generalized bipolar dimension.<\/p>\n The psychometric validity of the Radicalism-Conservatism Scale has been established through construct, convergent, discriminant, and criterion-related empirical investigations across diverse adult and student cohorts.<\/p>\n In their initial standardization sample of 212 subjects, Comrey and Newmeyer demonstrated that the 13 a priori attitude clusters exhibited substantial intercorrelations in hypothesized directions. Religiosity, severe treatment of criminals, capital punishment, moral censorship, service to country, anti-unionism, and weak federal government demonstrated significant positive intercorrelations, forming a cohesive conservative pole. Conversely, welfarism, pacifism, contraception, racial tolerance, world government, and service to the individual loaded consistently on the radical pole. Subsequent confirmatory investigations reported in John P. Robinson and Phillip R. Shaver's landmark compendium, Measures of Political Attitudes<\/em> (1969), reaffirmed that a generalized, unrotated first principal component or second-order factor accounted for upwards of 40% to 50% of the common variance among the subscales.<\/p>\n The RCS exhibits robust convergent validity when evaluated against external behavioral and demographic criteria:<\/p>\n The scale demonstrates adequate discriminant validity against measures of general cognitive ability (e.g., Wonderlic Personnel Test, Miller Analogies Test), showing negligible correlations ($r = -.08$<\/span> to $.12$<\/span>). Furthermore, Comrey and Newmeyer ensured that the parallel forms minimized confounding with acquiescence response set by incorporating systematically reversed items, ensuring that the primary factor reflects substantive attitudinal variance rather than mechanical response styles.<\/p>\n The Radicalism-Conservatism Scale possesses excellent psychometric reliability across internal consistency, parallel-forms equivalence, and temporal stability metrics.<\/p>\n A central design feature of the RCS is the exact structural alignment between Form A and Form B. When administered concurrently or in immediate succession to standardization samples, the correlation between Form A and Form B total scores ranged from $r = .85$<\/span> to $r = .91$<\/span>, indicating high parallel-form equivalence. This allows researchers to utilize either form interchangeably without compromising measurement calibration.<\/p>\n Split-half reliability coefficients, corrected via the Spearman-Brown prophecy formula, yielded estimates between $.87$<\/span> and $.93$<\/span> for the total 30-item composite scores across both forms. Individual subscales (which typically consist of two to four items each) demonstrate lower, yet psychometrically acceptable, internal consistency estimates (Cronbach's $\\alpha$<\/span> ranging from $.58$<\/span> to $.82$<\/span>), reflecting the deliberate brevity of each specific sub-facet battery.<\/p>\n In temporal stability evaluations spanning four- to eight-week test-retest intervals, the RCS demonstrated remarkable stability among adult populations, with test-retest reliability coefficients routinely falling between $r_{tt} = .82$<\/span> and $r_{tt} = .89$<\/span>. These metrics confirm that the RCS measures a stable, enduring sociopolitical orientation rather than transient, situational mood fluctuations.<\/p>\n The developmental psychometric architecture of the RCS was guided by rigorous factor-analytic extraction. Comrey and Newmeyer (1965) submitted the intercorrelations of the 13 hypothesized attitude sub-areas to an Exploratory Factor Analysis (EFA)<\/a> utilizing principal component extraction followed by orthogonal and oblique analytic rotations (specifically employing Comrey's tandem criteria and Varimax rotation).<\/p>\n The initial factor matrix revealed a massive first unrotated factor accounting for a predominant share of total variance. Following rotation, several clear, interpretable primary factors emerged, which directly corresponded to the theoretical dimensions:<\/p>\n When the oblique intercorrelations among these primary factors were factored at the second order, a single, definitive higher-order factor emerged. This second-order latent trait exhibited high loadings from all primary dimensions, demonstrating empirically that individual positions on moral, economic, international, and punitive issues are bound together by an overarching latent axis: Radicalism-Conservatism<\/strong>.<\/p>\n The structural characteristics of the Radicalism-Conservatism Scale are outlined below:<\/p>\n The Radicalism-Conservatism Scale was formally published in 1965<\/strong> by Andrew L. Comrey and John A. Newmeyer in The Journal of Social Psychology<\/em>. It was subsequently republished and documented for research dissemination by John P. Robinson and Phillip R. Shaver in 1969 through the Institute for Social Research (ISR)<\/a> at the University of Michigan, Ann Arbor.<\/p>\n As a historic psychometric instrument developed under academic research sponsorships and documented in open scholarly archives, the RCS resides in the public domain for academic, educational, and non-commercial scientific research.
