The Customer-Based Brand Competitiveness Scale (CBBC)<\/strong> is a psychometric instrument designed to capture consumers’ relative evaluations of how effectively a focal brand outperforms its direct competitors in the marketplace. Developed by Wangmo, Piehler, and Baumann (2025)<\/a>, the instrument addresses a critical theoretical and empirical gap in marketing and consumer psychology: while conventional customer-based brand equity (CBBE) measures predominantly evaluate brands in isolation (an absolute perspective), market competition inherently functions as a zero-sum, comparative decision environment. The CBBC scale conceptualizes brand competitiveness as a unidimensional, customer-evaluated relative construct consisting of seven operational items spanning perceived reputation, brand superiority, promise delivery, customer need fulfillment, comparative quality, market outperformance, and perceived market leadership.<\/p>\n The scale was developed and psychometrically validated across five diverse industry sectors in Australia\u2014Fast-Moving Consumer Goods (FMCG<\/a>), financial services, telecommunications, retail, and automotive. Following a rigorous three-stage scale development procedure encompassing qualitative consumer interviews, academic expert panel refinement, and three sequential quantitative studies, the instrument demonstrated exceptional psychometric integrity. Confirmatory factor analyses confirmed strict unidimensionality, yielding high internal consistency coefficients (Cronbach’s alpha and composite reliability consistently exceeding .90) and robust convergent, discriminant, and nomological validities. Administered on a 7-point Likert scale<\/a>, the CBBC provides scholars and brand strategists with a parsimonious, diagnostically sensitive, and generalizable tool for assessing comparative brand strength, modeling competitive market dynamics, and predicting consumer choice behavior.<\/p>\n Customer-based brand competitiveness, CBBC scale, relative brand equity, brand performance, comparative judgment, competitive advantage, psychometric validation, brand management, consumer psychology, market leadership<\/p>\n The Customer-Based Brand Competitiveness Scale was conceptualized, operationalized, and validated by an international team of marketing scholars and psychometric researchers specializing in brand strategy, consumer decision-making, and competitive positioning:<\/p>\n Correspondence regarding the scale’s empirical validation and structural parameters is documented in the seminal publication in the Journal of Product & Brand Management<\/em> (Wangmo et al., 2025).<\/p>\n In modern marketing literature and psychometric consumer research, the assessment of brand strength has long been dominated by Customer-Based Brand Equity (CBBE) models, such as those formulated by Aaker (1991)<\/a> and Keller (1993)<\/a>. Although these legacy frameworks provide deep insight into cognitive associations, perceived quality, and brand resonance, they systematically suffer from an “absolute perspective” bias: consumers are typically asked to evaluate a target brand in a perceptual vacuum (e.g., “Brand X is reliable,” “Brand X is of high quality”). However, consumer decision-making in naturalistic market settings is fundamentally comparative. A consumer rarely decides whether a brand is good in isolation; rather, they evaluate whether Brand X is better<\/em> than Brand Y or Brand Z at a given price point and usage context.<\/p>\n The primary purpose of the Customer-Based Brand Competitiveness (CBBC) Scale is to operationalize this long-neglected relative perspective<\/em>. The CBBC scale provides a standardized, methodologically robust instrument that forces a direct, comparative cognitive appraisal between a focal brand and its relevant market competitors. By doing so, the scale accomplishes several clinical, empirical, and strategic objectives:<\/p>\n The psychological construct measured by the CBBC scale is Customer-Based Brand Competitiveness<\/strong>. Conceptually, it is defined as a consumer’s holistic, cognitive-affective appraisal of a focal brand’s relative superiority and competitive market outperformance in relation to its salient category competitors. Although market competitiveness has traditionally been examined at the firm level using objective economic metrics\u2014such as relative market share, return on assets (ROA), or cost structures\u2014customer-based competitiveness captures the construct as it exists within consumer cognitive architecture.<\/p>\n Psychometrically, the CBBC is operationalized as a unidimensional construct<\/strong>. While competitive advantage manifests across multiple operational facets, consumer cognitive synthesis merges these components into an integrated, overarching appraisal of relative capability. The seven items of the CBBC capture seven essential facets of this unidimensional latent variable:<\/p>\n Because the construct is unidimensional, these facets do not constitute distinct mathematical subscales; rather, they serve as mutually reinforcing, high-loading indicators of a singular latent trait: the focal brand’s customer-perceived competitive edge.<\/p>\n The Customer-Based Brand Competitiveness Scale is grounded at the intersection of cognitive psychology, behavioral economics, and strategic brand management theories:<\/p>\n At the psychological core of the CBBC is Thurstone’s (1927) Law of Comparative Judgment<\/a>, which posits that the human cognitive system is fundamentally optimized for paired comparisons and relative discrimination rather than absolute magnitude estimation. When consumers encounter absolute scales, they mentally construct internal, often unmeasured reference points. Building on Festinger’s (1954) Social Comparison Theory<\/a> and adaptation-level paradigms (Helson, 1964<\/a>), the CBBC formalizes these reference points by setting the competitive field as the explicit anchor. Relative evaluations eliminate the cognitive ambiguity inherent in absolute semantic scales.<\/p>\n From strategic management, the scale translates Barney’s (1991) Resource-Based View (RBV)<\/a> and Porter’s (1985) Competitive Advantage<\/a> framework into cognitive representations. In industrial organization and strategic management, competitive advantage exists when a firm implements a value-creating strategy not simultaneously being implemented by current or prospective rivals. The CBBC operationalizes this premise from the demand side: competitive advantage is meaningless unless it is perceived, decoded, and validated by the end customer.<\/p>\n Under Signaling Theory (Spence, 1973; Erdem & Swait, 1998)<\/a>, brand names act as market signals designed to reduce information asymmetry between buyers and sellers. When consumers evaluate dimensions like promise delivery and reputation relatively, they are weighing the credibility, clarity, and consistency of the focal brand’s signals against the competing noise of rival brands. The CBBC captures the net signal strength of the focal brand within a crowded information environment.<\/p>\n The psychometric validation of the CBBC scale followed the rigorous methodological guidelines outlined by Churchill (1979)<\/a> and DeVellis (2016)<\/a>, utilizing a multi-stage empirical pipeline across multiple independent consumer cohorts:<\/p>\n Item generation commenced with comprehensive qualitative consumer discovery (semi-structured in-depth interviews) exploring how everyday buyers define “competitiveness” and what leads them to categorize one brand as clearly superior to another. An initial pool of potential indicators was reviewed and refined by a panel of expert academic researchers in brand management and psychometrics. Items displaying semantic redundancy, double-barreled phrasing, or context-specific idiosyncrasies were systematically removed, yielding an initial candidate set for quantitative distillation.<\/p>\n Convergent validity was comprehensively established across all validation studies. Confirmatory factor analyses (CFA) revealed that all seven standardized factor loadings (λ<\/a>) were exceptionally high and statistically significant at p<\/em> < .001, consistently exceeding the conservative .70 benchmark (loadings ranged from .78 to .92 across distinct industry samples). Furthermore, the Average Variance Extracted (AVE<\/a>) for the latent construct substantially surpassed the established .50 threshold, routinely recording values above .65 to .75 across the five industry datasets (FMCG, finance, telecommunications, retail, automotive), confirming that the construct explains the overwhelming majority of indicator variance<\/span>.<\/p>\n Discriminant validity was rigorously evaluated against related constructs, including overall customer satisfaction, absolute brand equity (CBBE), brand trust, and customer loyalty. The scale successfully passed both classical and cutting-edge criteria:<\/p>\n Nomological network testing confirmed strong, theoretically sound structural pathways. When modeled within structural equation models, the CBBC demonstrated robust predictive power regarding key consumer outcomes. Specifically, CBBC scores significantly and positively predicted:<\/p>\n The Customer-Based Brand Competitiveness Scale displays world-class psychometric reliability across disparate market conditions, demographically diverse consumer groups, and product versus service industries.<\/p>\n Across the quantitative validation studies reported by Wangmo et al. (2025), internal consistency was examined using multiple complementary statistical metrics:<\/p>\n Item-total correlations for all seven items routinely exceeded .75 across split-sample cross-validation procedures. Squared multiple correlations ($R^2$<\/span>) for individual indicators indicated that between 60% and 85% of each item’s variance was directly accounted for by the underlying latent customer-based brand competitiveness factor, reflecting minimal measurement error and superior test-retest resilience across repeated cross-sectional implementations.<\/p>\n The underlying dimensionality of the CBBC was extensively investigated through both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) during its phased scale development.<\/p>\n During initial quantitative testing, principal axis factoring with promax rotation was executed on candidate items. The Kaiser-Meyer-Olkin (KMO<\/a>) measure of sampling adequacy consistently exceeded .92 (indicating marvelous data-to-factor suitability), and Bartlett’s Test of Sphericity was statistically significant ($p < .001$<\/span>). Both scree plot inspection and parallel analysis unambiguously converged on a single-factor solution<\/strong>, with the primary factor accounting for over 65% to 73% of the total cumulative variance. No secondary factors achieved eigenvalues exceeding 1.0.<\/p>\n To confirm this unidimensional structure, structural equation modeling with maximum likelihood estimation was conducted across independent cross-validation samples. The unidimensional 7-item model demonstrated outstanding fit to the empirical data across all industries, satisfying or surpassing the most stringent cutoff criteria recommended by Hu and Bentler (1999)<\/a>:<\/p>\n Multi-group CFA demonstrated configural<\/em>, metric<\/em>, and scalar invariance<\/em> across product versus service categories and across consumer demographic strata (gender, age brackets). This confirms that observed score variations on the CBBC reflect true structural differences in perceived competitiveness rather than measurement artifact or semantic divergence across different customer segments.<\/p>\n The operational specifications of the Customer-Based Brand Competitiveness Scale are structured as follows:<\/p>\n The Customer-Based Brand Competitiveness Scale was developed and published in 2025<\/strong> by Gedun Wangmo, Rico Piehler, and Chris Baumann in the peer-reviewed scholarly outlet Journal of Product & Brand Management<\/em>.<\/p>\n The following foundational and empirical references underpin the design, validation, and theoretical modeling of the CBBC:<\/p>\n Instructions:<\/strong> Please indicate your level of agreement with each of the following statements regarding [Brand X] in comparison to other competing brands in the same category.<\/p>\n Response Scale:<\/strong> 7-point Likert scale (1 = Strongly disagree, 7 = Strongly agree)<\/span><\/p>\n Scoring Protocol:<\/strong> All items are positively keyed.
