The Brown Locus of Control Scale<\/strong> (BLOCS<\/a>) is a 25-item multidimensional self-report psychometric instrument designed to evaluate an individual’s generalized expectancies regarding the determinants of life outcomes. Developed by educational psychometrician Ric Brown (1983, 1990), the BLOCS expands upon traditional unidimensional conceptualizations of Rotter’s internal-external locus of control construct<\/a> and refines the multi-faceted models introduced by Hanna Levenson<\/a>. The instrument measures three empirically and theoretically distinct dimensions: Internal Control<\/em> (the belief that personal effort, agency, and competence direct outcomes; 9 items), External Social Control<\/em> (the perception that social hierarchies, institutional gatekeepers, interpersonal networking, and group pressures govern reinforcement; 9 items), and External Other Control<\/em> (the attribution of life events to chance, luck, systemic fate, historical traditions, or transcendent forces; 7 items). Items are calibrated using a 6-point Likert-type response format ranging from 1 (“Very Strongly Disagree”) to 6 (“Very Strongly Agree”).<\/p>\n Psychometric evaluations demonstrate moderate to high internal consistency across subscales, with reported Cronbach’s alpha coefficients of .74 for Internal Control, .71 for External Social Control, and .66 for External Other Control. Temporal stability assessments indicate robust test-retest reliability across a two-week interval: .88, .91, and .84, respectively. Exploratory and confirmatory factor analyses, including cross-cultural replications (e.g., Brown & Marcoulides, 1996), substantiate the three-factor orthogonal structure. The BLOCS serves as a valuable assessment tool within clinical, educational, occupational, and cross-cultural research, offering an explicit distinction between interpersonal-institutional determinants of control and abstract-fatalistic expectations.<\/p>\n Brown Locus of Control Scale, BLOCS, locus of control, internal locus of control, external social control, external other control, attribution theory, social learning theory, psychometrics, factor analysis, agency, fatalism<\/p>\n The Brown Locus of Control Scale was developed by Ric Brown<\/strong>, Ed.D., an educational researcher and psychometrician specializing in measurement, evaluation, and educational psychology. Dr. Brown conducted foundational research while affiliated with institutions including California State University, Fresno. Additional psychometric modeling and structural invariance evaluations of the BLOCS were conducted in collaboration with George A. Marcoulides<\/strong>, Ph.D., a distinguished quantitative psychometrician and methodologist recognized for structural equation modeling (SEM<\/a>) and multivariate statistics.<\/p>\n The primary purpose of the Brown Locus of Control Scale (BLOCS) is to provide an accurate, multidimensional profile of an individual’s causal attributions concerning life achievements, social interactions, and personal difficulties. Prior to the development of the BLOCS, traditional psychological research predominantly relied on Rotter’s (1966) unidimensional Internal-External (I-E) scale. While revolutionary, the binary conceptualization treated external control as a monolithic entity, conflating random chance with systemic social influence and political power. The BLOCS addresses these limitations by differentiating between personal agency, social-relational influence, and fatalistic forces.<\/p>\n In clinical, educational, and organizational settings, understanding this distinction is critical:<\/p>\n The core psychological construct measured by the BLOCS is locus of control of reinforcement<\/em>, defined as the degree to which individuals expect that a reinforcement or outcome of their behavior is contingent upon their own characteristics versus the degree to which they perceive it as controlled by outside forces. Rather than conceptualizing this construct as a single continuum spanning from internality to externality, the BLOCS specifies three structurally independent dimensions:<\/p>\n The Internal Control<\/em> dimension measures self-efficacy, personal agency, effort expectancy, and behavioral accountability. Individuals scoring high on this dimension operate under the conviction that personal actions, diligence, strategic preparation, and competence directly govern life outcomes. Illustrative items include: “Most of the time, I control what happens in my life”<\/em> and “Hard work will get me where I want to go.”<\/em> High internality is strongly correlated with academic achievement, self-regulatory capacity, problem-focused coping mechanisms, and proactive health behaviors.<\/p>\n The External Social Control<\/em> dimension quantifies the extent to which an individual views outcomes as determined by social networks, societal power dynamics, institutional hierarchies, and interpersonal dependencies. This dimension reflects an awareness of sociological realities, corporate power structures, peer influence, and nepotism. Exemplified by items such as “Getting ahead is a matter of pleasing people in power”<\/em> and “Strong pressure groups determine my role in society,”<\/em> this subscale captures the pragmatic or cynical acknowledgment that individual ability is constrained or facilitated by the sociopolitical environment.<\/p>\n The External Other Control<\/em> dimension assesses fatalistic, metaphysical, and stochastic attributions. Individuals with elevated scores on this factor perceive personal outcomes as dictated by unpredictable luck, immutable fate, transcendental forces, religious predestination, or historical customs. Reflected in items such as “My life is often affected by fate”<\/em> and “Accidental happenings have a lot to do with my life,”<\/em> this construct is closely associated with fatalism, passive coping strategies, existential resignation, and an externalized attributional style that detaches behavioral effort from outcome expectancy.<\/p>\n The theoretical foundations of the Brown Locus of Control Scale are rooted in Rotter’s (1954, 1966) Social Learning Theory<\/a>, Weiner’s (1979) Attribution Theory<\/a>, and Levenson’s (1974) Tripartite Locus of Control Model<\/a>.<\/p>\n Julian Rotter formulated locus of control within a behavioral formula: Behavior Potential = f(Expectancy & Reinforcement Value)<\/em>. Rotter argued that when individuals generalize the expectancy that reinforcements follow personal skill or effort, they exhibit internal control; conversely, if reinforcements are viewed as unpredictable or controlled by external agents, external control emerges. However, empirical researchers early on noted significant variance within external locus of control that Rotter’s forced-choice scale could not parse<\/span>.<\/p>\n Hanna Levenson (1974) challenged Rotter’s unidimensional conceptualization by separating external control into two discrete domains: Powerful Others<\/em> and Chance<\/em>. Levenson argued that expecting powerful humans to govern reinforcement implies an ordered, predictable social world wherein an individual can potentially maneuver or negotiate, whereas believing in chance reflects an unpredictable, chaotic reality.<\/p>\n Ric Brown (1983, 1990) extended Levenson’s conceptual advances to better reflect contemporary socio-educational realities. In the BLOCS framework:<\/p>\n The psychometric validity of the Brown Locus of Control Scale has been verified across multiple studies assessing construct, concurrent, convergent, and cross-cultural validity.<\/p>\n In the foundational validation study reported by Brown (1990), exploratory factor analysis supported the construct validity of the 25 items across three distinct dimensions. The empirical separation of the External Social and External Other dimensions demonstrated that external control is not a homogeneous psychometric entity. Cross-cultural construct validity was further substantiated by Brown and Marcoulides (1996), who tested the three-factor measurement model using structural equation modeling across distinct ethnic and cultural cohorts, establishing acceptable metric invariance.<\/p>\n Concurrent validity was established through systematic comparisons with existing personality, behavioral, and demographic indices across multiple empirical samples (Brown, 1983, 1990):<\/p>\n The Brown Locus of Control Scale possesses well-documented internal consistency and temporal stability metrics across diverse research samples.<\/p>\n As documented in the 1990 validation study encompassing multiple normative cohorts, the Cronbach’s alpha coefficients for the three subscales are:<\/p>\n While the coefficient for the External Other subscale is slightly below the conventional .70 benchmark\u2014partially attributable to its shorter length (7 items) and the heterogeneous nature of fatalistic, lucky, and traditional beliefs\u2014the subscale retains adequate psychometric utility for group-level comparative and correlational research.<\/p>\n Stability across time was evaluated over a two-week interval using a subsample of 92 university students drawn from the original validation research cohort (Brown, 1990). Pearson product-moment stability coefficients demonstrated strong temporal stability across all three dimensions:<\/p>\n These coefficients confirm that the BLOCS measures stable cognitive personality dispositions rather than transient emotional or psychological states.<\/p>\n The structural composition of the BLOCS was derived via principal axis factor analysis with both orthogonal (Varimax) and oblique rotations (Brown, 1990). The empirical extraction yielded a definitive three-factor solution based on the scree test and eigenvalue criteria (> 1.0), accounting for a substantial proportion of the total item variance<\/span>.<\/p>\n In subsequent confirmatory factor analyses (CFA<\/a>), Brown and Marcoulides (1996) tested the goodness-of-fit of this tripartite structure across multi-ethnic student groups. The hypothesized three-factor model yielded satisfactory comparative fit indices (CFI > .90; RMSEA ≤ .06), demonstrating configural and metric invariance across demographic samples<\/span>.<\/p>\n The Brown Locus of Control Scale was first introduced in empirical research by Ric Brown in 1983<\/strong>, with comprehensive psychometric validation and subscale properties published in 1990<\/strong> in Educational and Psychological Measurement<\/em>. The scale was established as an open-access psychometric instrument for non-commercial scientific, educational, and clinical research purposes.<\/p>\n No licensing fee is required for academic investigations, university research, or non-commercial clinical evaluation.
