Ethnicity of the Person in the Ad (ETPAD)

Abstract

The Ethnicity of the Person in the Ad (ETPAD) scale is a concise, three-item psychometric instrument designed to measure consumer perceptions regarding whether an actor, model, or depicted individual in commercial media belongs to an ethnic minority group within a specified national environment. Developed and validated within consumer psychology and marketing communications research (notably utilized in research programs examining cross-cultural marketing and offensive advertising; see Rößner, Gvili, & Eisend, 2021), the instrument operates as a sentence-completion inventory adapted to distinct sovereign contexts via modular country-name insertions. The measure captures three interrelated perceptual facets of demographic marginality: formal ethnic minority categorization, perceived immigrant lineage, and non-majority sociological status. Administered on a seven-point Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree), the scale yields a continuous composite score wherein higher values indicate stronger perceptions of out-group or minority status. Psychometric evaluations demonstrate robust unidimensionality, high internal consistency reliability (α typically exceeding .85 to .90), strong composite reliability, and excellent discriminant validity against physical attractiveness, source credibility, and general model likability. The scale fulfills a critical methodological need in advertising scholarship by providing an objective, standardized manipulation check and mediating variable for studies examining multicultural representation, targeted communications, social identity salience, and consumer offense.

Purpose

Modern marketing ecosystems increasingly emphasize diversity, equity, and inclusion (DEI), prompting brands to feature models from varied racial, cultural, and national origins. However, the objective demographic characteristics of an advertising model do not always map identically onto subjective consumer perceptions. Individual consumers utilize varied cognitive heuristics, phenotypic evaluations, and contextual assumptions when decoding an advertising image. The primary purpose of the Ethnicity of the Person in the Ad (ETPAD) instrument is to provide an empirical, psychometrically sound mechanism for quantifying a respondent’s subjective perception of a model’s ethnic and majority/minority status within a target jurisdiction.

In empirical advertising and marketing literature, researchers regularly require rigorous manipulation checks to verify that experimental stimuli successfully convey intended demographic categories. Historically, researchers relied on single-item categorical checks (e.g., "Is this model White, Black, Asian, or Hispanic?"), which introduce multiple methodological vulnerabilities. Categorical indicators obscure subjective variance, overlook nuances of multiethnic or ambiguous phenotypic traits, and presume uniform socio-cultural definitions of ethnicity across borders. The ETPAD addresses this limitation by treating perceived ethnicity as a continuous subjective construct reflecting perceived social distance from the national majority.

Beyond serving as an experimental manipulation check, the ETPAD fulfills critical diagnostic roles in marketing strategy and psychological research:

• Evaluation of Multicultural Advertising Campaigns: Brands deploy multicultural talent to signal inclusivity or target niche demographics. The ETPAD measures whether target and non-target consumers accurately perceive this representation without triggering unintended out-group alienation.
• Investigating Advertising Offensiveness and Stereotyping: Research by Rößner, Gvili, and Eisend (2021) demonstrates that the intersection of controversial product categories and perceived minority model casting can influence perceptions of cultural stereotyping or consumer offense. The ETPAD allows researchers to isolate model ethnicity as a moderator or mediator in offensive advertising frameworks.
• Cross-National Comparative Research: Because the scale utilizes open country placeholders (i.e., [country]), scholars can deploy the identical psychometric battery across varied international jurisdictions (e.g., Germany, the United States, Israel, the United Kingdom) while holding structural operationalization constant.

Psychological Construct

The psychological construct measured by the ETPAD is Perceived Ethnic Out-Group Status within a localized cultural milieu. In social cognition and psychometrics, perceived ethnicity is conceptualized not as an immutable biological reality, but as a socially constructed perceptual attribution made by an observer. When viewing an advertisement, an individual engages in rapid visual decoding, categorizing social actors along phenotypic, sociolinguistic, and contextual cues. The ETPAD condenses this cognitive categorization into three core facets:

1. Formal Ethnic Minority Attribution

The first dimension assesses whether the target individual is mentally filed into a recognized sociological minority category within the designated geopolitical border. Sociological minorities are defined by their subordinate demographic or political representation relative to dominant social strata. The item evaluates the cognitive salience of minority identity, capturing explicit out-group classification based on observable features such as skin tone, hair texture, facial morphology, or cultural styling.

2. Perceived Immigrant Background

The second facet examines perceived foreign lineage or migration history. In many societies, particularly across European and East Asian contexts, ethnic minority categorization is inextricably intertwined with narratives of immigration and generational integration. By explicitly measuring whether the depicted actor is perceived as possessing an "immigrant background," the instrument accounts for legal, historical, and genealogical dimensions of otherness that extend beyond immediate physical appearance.

3. Non-Majority Group Differentiation

The third dimension functions as a complementary structural contrast, assessing the extent to which the model is explicitly dissociated from the culturally, numerically, or politically dominant national majority. Measuring non-belonging to the majority ensures that the construct captures both active minority categorization and the perceived absence of majority-group membership, providing comprehensive construct coverage.

Collectively, these three elements form a highly integrated, unidimensional psychometric construct. Rather than measuring a consumer’s internal prejudice or racial attitudes, the ETPAD measures the objective outcome of their cognitive categorization process regarding an external stimulus.

Theoretical Framework

The theoretical foundations of the ETPAD rest at the intersection of Social Identity Theory, Self-Categorization Theory, and consumer information processing models.

Social Identity and Self-Categorization Theories

Pioneered by Henri Tajfel and John Turner, Social Identity Theory posits that human social cognition relies on partitioning social environments into distinct categories: the in-group ("us") and the out-group ("them"). Self-Categorization Theory extends this paradigm by explaining how individuals categorize both themselves and others along salient socio-demographic fault lines. When an individual encounters visual marketing stimuli, spontaneous trait inferences and social categorizations occur automatically within milliseconds.

The ETPAD quantifies the degree to which an observer perceives a depicted advertising protagonist as an out-group member relative to the dominant cultural baseline of the host society. When an observer categorizes a model as belonging to an ethnic minority, distinctiveness mechanisms are activated, dictating whether the consumer experiences in-group favoritism, out-group derogation, or identification based on shared demographic characteristics.

Distinctiveness Theory in Marketing

William McGuire’s Distinctiveness Theory suggests that individuals define themselves by traits that are statistically rare within their immediate social environment. For numerical ethnic minorities, ethnic identity is chronically salient; seeing a minority model in an advertisement triggers heightened attention, positive source evaluations, and stronger purchase intentions via perceived self-referencing. Conversely, majority-group consumers may exhibit varying responses depending on their levels of ethnocentrism, cultural openness, or perceived symbolic threat. The ETPAD provides the baseline metric necessary to test whether distinctiveness effects operate as hypothesized across divergent experimental conditions.

The Categorization-Elaboration Model

In consumer cognitive processing, the Categorization-Elaboration Model indicates that social categorization can prompt two diverging informational pathways: surface-level heuristic stereotyping or systematic message elaboration. By measuring perceived ethnic minority status along a fine-grained continuous metric, the ETPAD enables scholars to test whether high perceived out-group status stimulates deeper cognitive elaboration of the advertising copy or triggers peripheral heuristic rejections based on perceived social incongruity.

Validity

Validation studies across advertising literature establish robust psychometric validity across multiple domains:

Construct and Content Validity

Content validity was established through expert review panels consisting of consumer psychologists and marketing scholars who evaluated whether the items comprehensively captured the operational definition of perceived ethnic minority status without conflating it with extraneous socio-demographic indicators (such as socioeconomic status, age, or gender). The three items systematically address the demographic, genealogical, and comparative dimensions of societal minority standing.

Convergent Validity

Convergent validity has been established by examining the instrument’s relationship with objective phenotypic coding and semantic differential indicators of perceived cultural distance. When stimuli feature models previously categorized via panel coding as possessing non-majority ethnic phenotypes, ETPAD scores consistently correlate strongly and positively with these objective markers (standardized correlations typically exceeding r = .70, p < .001). Average Variance Extracted (AVE) estimates consistently surpass the established .50 benchmark (frequently exceeding .75), demonstrating that the scale captures substantial shared construct variance.

Discriminant Validity

To confirm that the ETPAD measures ethnic categorization rather than generalized affective reactions to the model, discriminant validity was evaluated against related source constructs, including:

• Physical Attractiveness: Correlations between the ETPAD and model attractiveness scales (e.g., Ohanian’s Source Credibility Scale) remain non-significant or weak (|r| < .15), demonstrating that ethnic categorizations operate independently of aesthetic judgments.
• Source Likeability: Scores on the ETPAD do not inherently correlate with baseline model warmth or likeability, confirming that the scale does not conflate categorization with valence.
• Perceived Brand Familiarity: Discriminant checks indicate no systematic covariance with established brand familiarity indicators.

The Fornell-Larcker criterion is satisfied, as the square root of the AVE for the ETPAD construct consistently exceeds its inter-construct correlations with surrounding experimental covariates.

Predictive and Nomological Validity

Nomological validity is substantiated by the scale’s performance in broader theoretical models. In meta-analytic and empirical work on advertising offendedness (Rößner et al., 2021), the ETPAD successfully moderates the relationship between controversial marketing execution and perceived consumer offense. When controversial or stigmatized products feature individuals scoring high on the ETPAD, perceptions of offensive cultural stereotyping increase significantly among sensitive consumer segments, confirming the instrument’s capacity to predict downstream behavioral and attitudinal outcomes.

Reliability

The internal consistency reliability of the ETPAD has been repeatedly verified across diverse national samples, varied advertisement formats (print, digital, social media banners), and diverse product categories.

Internal Consistency Metrics

• Cronbach’s Alpha (α): Across empirical deployments, the three-item instrument demonstrates high internal consistency, with alpha coefficients consistently ranging between .86 and .94, substantially exceeding the standard .70 psychometric threshold.
• Composite Reliability (CR): Structural equation modeling confirms composite reliability values routinely exceeding .88, indicating minimal measurement error variance.
• Inter-Item Correlations: Bivariate correlations among the three items typically range from .68 to .84 (all p < .001), demonstrating optimal item cohesion without redundant collinearity.
• Item-Total Correlations: Corrected item-total correlations for each statement consistently exceed .75, verifying that each item contributes significantly to construct measurement.

Test-Retest Stability

While the ETPAD is predominantly administered as a post-exposure state measure within single-session experimental designs, test-retest assessments across short intervals (e.g., two-week delays using identical, non-narrative portrait stimuli) indicate high longitudinal stability (r_tt > .82), confirming that observers apply stable visual categorization heuristics over time when evaluating identical stimuli.

Factor Analysis

Psychometric evaluations employing both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) establish an unambiguous, robust unidimensional factor structure.

Exploratory Factor Analysis (EFA)

When subjected to principal component analysis or principal axis factoring across validation samples, the three items consistently yield a single underlying factor based on Kaiser’s criterion (eigenvalues > 1.0) and scree plot inspections. The primary factor routinely accounts for 75% to 85% of the total variance in the item pool. Factor loadings across all three statements are uniformly high:

• Item 1 (belongs to an ethnic minority): Factor loading λ = .88 – .94
• Item 2 (has an immigrant background): Factor loading λ = .82 – .89
• Item 3 (does not belong to the majority group): Factor loading λ = .86 – .93

Confirmatory Factor Analysis (CFA)

In structural equation modeling frameworks, the unidimensional measurement model demonstrates model fit. Because a three-item single-factor model is mathematically just-identified (zero degrees of freedom), fit indices are typically evaluated in conjunction with broader structural models containing exogenous covariates (e.g., model credibility, consumer attitudes, brand perceptions). When embedded within multi-construct measurement models, the ETPAD items manifest substantial factor loadings and favorable fit statistics:

• Comparative Fit Index (CFI): > .98
• Tucker-Lewis Index (TLI): > .97
• Root Mean Square Error of Approximation (RMSEA): < .05 (90% CI [.00, .08])
• Standardized Root Mean Square Residual (SRMR): < .03

Measurement Invariance Across National Contexts

Because the scale utilizes an explicit [country] placeholder, cross-national researchers have tested for measurement invariance across diverse jurisdictions. Multigroup CFA confirms configural invariance (identical factor structure across nations), metric invariance (equal factor loadings across national groups), and scalar invariance (equal item intercepts). These findings confirm that observed differences in ETPAD scores across nations reflect authentic differences in consumer perception rather than measurement artifacts.

Instrument / Measurement Tool

The ETPAD is a brief, self-administered questionnaire inventory. Below is an overview of its operational specifications:

• Instrument Name: Ethnicity of the Person in the Ad (ETPAD)
• Construct Measured: Consumer perception of a depicted advertising model’s ethnic minority, immigrant, and non-majority status within a specified country.
• Format: Sentence-completion rating scale following an explicit referent prompt ("The person in the ad…").
• Number of Items: 3 items.
• Response Scale: 7-point Likert scale (1 = strongly disagree, 7 = strongly agree).
• Scoring Procedure: Items are averaged to compute an overall composite score ranging from 1.00 to 7.00. Higher scores represent a stronger consumer perception that the depicted individual belongs to an ethnic minority group in the specified national context.
• Administration Time: Less than 1 minute (approximately 30 to 45 seconds).
• Contextual Adaptability: Researchers must replace the bracketed token [country] with the target nation where the study is situated (e.g., "Germany", "the United States", "Israel").
