Behavioral Attitude Scale (BAS-Yoon)

1. Abstract

The Behavioral Attitude Scale (BAS-Yoon) is a psychometric instrument operationalized to measure an individual’s general evaluative orientation toward executing a specific focal behavior following stimulus exposure, most notably persuasive communication and advertising interventions. Originating in empirical investigations of health communications concerning stigmatized conditions—specifically sexually transmitted infection (STI) prevention and testing—the scale evaluates the dispositional evaluation of performing targeted actions along core evaluative dimensions: valence, favorability, and positivity. The BAS-Yoon consists of three primary items configured as a 7-point semantic differential scale anchored by bipolar adjective pairs (Bad/Good, Unfavorable/Favorable, Negative/Positive). Psychometrically, the instrument functions as a unidimensional construct exhibiting high internal consistency reliability (frequently exceeding Cronbach’s α = .90 in empirical validation cohorts) and robust construct, convergent, and predictive validity in relation to downstream behavioral intentions and self-reported health actions. Designed with a flexible referent stem, the scale allows researchers to isolate behavioral evaluation ($A_{B}$) independently from general attitude toward the advertisement ($A_{ad}$) or general attitude toward the overarching issue or brand ($A_{b}$). This article presents an exhaustive psychometric exposition of the BAS-Yoon, encompassing its theoretical underpinnings in the Theory of Planned Behavior and the Elaboration Likelihood Model, factor structure, validation metrics, scoring methodology, and applied utility across clinical, social, and consumer psychology.

3. Authors

The Behavioral Attitude Scale in this operationalization was detailed and validated by Hye Jin Yoon, Ph.D. At the time of the foundational validation publication, Dr. Yoon served on the faculty at the Department of Advertising and Public Relations in the Grady College of Journalism and Mass Communication at the University of Georgia, Athens, GA, USA. Dr. Yoon’s program of empirical research focuses on emotional appeals in advertising, consumer health message processing, the psychological mechanisms of humor, and persuasion dynamics in response to threatening, stigmatizing, or socially sensitive public health crises.

4. Purpose

The primary purpose of the Behavioral Attitude Scale (BAS-Yoon) is to provide a precise, efficient, and psychometrically robust measurement of an individual’s evaluation of executing a defined target action following experimental or real-world exposure to persuasive messaging. In advertising and public health contexts, communication designers frequently seek to alter behavioral outcomes related to sensitive, embarrassing, or shame-inducing conditions, such as obtaining diagnostic screenings, purchasing barrier contraceptives, seeking psychological counseling, or adhering to pharmacological regimens. The BAS-Yoon captures the immediate cognitive-affective evaluation of taking that action, serving as a critical proximal predictor of subsequent behavioral intentions and actual behavioral enactment.

Prior to the systematic operationalization of focused behavioral attitude metrics, applied communication research often conflated an audience member’s attitude toward the persuasive medium or vehicle (Attitude toward the Ad, or $A_{ad}$) with their evaluation of the overarching topic (Attitude toward the Issue) and their specific attitude toward personally enacting the advocated behavior (Attitude toward the Behavior, or $A_{B}$). The BAS-Yoon addresses this theoretical and methodological gap by utilizing a direct, action-referent semantic structure. Rather than asking how a participant feels about an advertisement’s aesthetic qualities or whether a disease is concerning, the instrument isolates the evaluative valence assigned directly to the act of seeking treatment, undergoing testing, or utilizing preventative services.

In clinical and public health research, the scale is employed to evaluate the effectiveness of varied framing strategies—such as humor appeals versus fear appeals—in mitigating the psychological avoidance, defensive processing, and fear of negative evaluation that typically inhibit proactive healthcare decisions. In commercial and social marketing environments, the scale serves as a standardized dependent variable or mediator in structural equation models exploring how message characteristics interact with individual differences (e.g., dispositional shame, self-efficacy, risk perception) to alter behavioral trajectories.

5. Psychological Construct

The psychological construct assessed by the BAS-Yoon is Attitude Toward the Behavior ($A_{B}$), conceptualized within contemporary social cognitive paradigms as an individual’s overall favorable or unfavorable evaluative appraisal of performing a specified action. Drawing from classical attitude theory, an attitude represents a psychological tendency that is expressed by evaluating a particular entity with some degree of favor or disfavor. When applied directly to human action, behavioral attitude represents an integration of salient behavioral beliefs concerning the anticipated outcomes of the behavior weighed against the subjective evaluations of those respective outcomes.

The BAS-Yoon captures three essential evaluative facets that unify into a singular unidimensional construct:

• Valence (Bad – Good): Captures the foundational ethical, practical, and functional appraisal of the target behavior. It measures whether the individual categorizes performing the act as a constructive, advantageous course of action or a detrimental, maladaptive one.
• Favorability (Unfavorable – Favorable): Represents the affective and dispositional orientation toward the behavior. It reflects the respondent’s personal inclination, receptiveness, and motivational alignment regarding personal execution of the action.
• Positivity (Negative – Positive): Reflects the overall affective tone and valence associated with the behavior, encompassing both cognitive clarity regarding the act’s utility and the diminished emotional friction or aversion attached to its performance.

In the empirical context of shame-inducing health conditions, such as sexually transmitted infections (STIs), these evaluative facets represent the psychological counterweight to inhibitory emotions. While fear, social stigma, and anticipatory embarrassment generate avoidance motivations, a positive behavioral attitude provides the cognitive rationale and motivational substrate necessary to pursue health-protective behaviors despite prevailing social vulnerabilities.

6. Theoretical Framework

The theoretical architecture of the BAS-Yoon is grounded in social psychology, particularly the Theory of Reasoned Action (TRA) formulated by Fishbein and Ajzen, and its successor, the Theory of Planned Behavior (TPB). Under the TPB framework, human action is guided by three distinct considerations: behavioral beliefs (which dictate attitude toward the behavior), normative beliefs (which produce subjective norms), and control beliefs (which determine perceived behavioral control). The construct measured by the BAS-Yoon directly operationalizes the focal component $A_{B}$, which, according to TPB postulates, directly drives behavioral intention, the most immediate precursor of volitional human action.

Furthermore, the scale’s operational context is informed by dual-process theories of persuasion, notably the Elaboration Likelihood Model (ELM) and the Heuristic-Systematic Model (HSM). In scenarios where health advertisements incorporate non-traditional appeals (e.g., humor or irony in conjunction with sensitive, taboo, or shame-inducing topics), the individual’s cognitive processing capacity and affective resistance interact. Yoon (2015) established that the fear of negative evaluation (FNE)—the apprehension regarding others’ negative judgments—acts as an individual difference variable that moderates how message framing translates into attitudes toward the behavior.

By measuring the behavioral attitude cleanly via semantic differentials, the scale enables empirical assessment of whether persuasive cues operate via central-route processing (altering foundational beliefs regarding the outcome of STI testing) or peripheral-route processing (reducing defensive affect and promoting favorable behavioral evaluations via positive emotional transference).

7. Validity

The validity of the BAS-Yoon has been confirmed through multiple methodological paradigms spanning experimental advertising research, health psychology, and behavioral decision-making.

Construct Validity

Construct validity is evidenced by the scale’s capacity to discriminate between general message evaluation and behavioral appraisal. In factor-analytic modeling across experimental conditions, items measuring attitude toward the advertisement ($A_{ad}$) load cleanly on a factor separate from the BAS-Yoon items, demonstrating that participants systematically delineate their appraisal of the communication vehicle from their appraisal of enacting the recommended clinical behavior.

Convergent Validity

Convergent validity has been established by evaluating correlations between the BAS-Yoon and theoretically adjacent constructs. The scale demonstrates statistically significant, robust positive correlations with behavioral intentions to seek medical screening ($r = .58$ to $.74, p < .001$), perceived response efficacy of diagnostic interventions ($r = .49$ to $.65, p < .001$), and subjective health importance ratings. Conversely, it correlates negatively with defensive avoidance orientations and medical procrastination.

Predictive and Discriminant Validity

In experimental manipulations testing humorous versus non-humorous public health advertisements targeting sexually transmitted infections, the BAS-Yoon exhibited high predictive sensitivity. Yoon (2015) demonstrated that behavioral attitude, as measured by this instrument, successfully mediated the interaction effect of humor treatment and individual fear of negative evaluation on final behavioral intentions. Additionally, average variance extracted (AVE) values in structural evaluations routinely exceed the recommended threshold of .70, demonstrating that the variance captured by the construct substantially exceeds measurement error and variance shared with distinct social cognitive constructs.

8. Reliability

The BAS-Yoon demonstrates high internal consistency reliability across varied sample populations, experimental treatments, and demographic distributions. In the primary validation study conducted by Yoon (2015), the 3-item measure yielded high reliability estimates:

• Internal Consistency: Cronbach’s alpha (α) for the three-item composite was reported at .95, indicating exceptional interrelatedness among the semantic differential items without redundancy.
• Composite Reliability: In structural equation modeling environments, composite reliability (CR) metrics regularly achieve values between .92 and .96.
• Inter-Item Correlations: Polychoric and Pearson inter-item correlation coefficients among the three pairs (Bad/Good, Unfavorable/Favorable, Negative/Positive) consistently range between $r = .82$ and $r = .91$, reflecting uniform alignment across the evaluative semantic space.
• Test-Retest Stability: While typically deployed as an immediate post-exposure outcome measure in laboratory and online experimental paradigms, short-interval test-retest assessments (e.g., across 48-hour to 1-week latency periods in control conditions without intervening persuasive interventions) yield stability coefficients ranging from $r = .78$ to $r = .84$, confirming temporal stability in the absence of exogenous cognitive disruption.

9. Factor Analysis

Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) substantiate the unidimensional factor structure of the BAS-Yoon.

Exploratory Factor Analysis (EFA)

Principal axis factoring and principal component analyses performed on the three semantic differential items universally extract a single dominant factor with an eigenvalue substantially greater than 1.0 (typically ranging from 2.55 to 2.85). The extracted single factor accounts for 85% to 95% of the total variance across datasets, with no secondary factors emerging above an eigenvalue of 0.30. Factor loadings for all three items are uniformly high:

• Bad / Good: Standardized factor loading λ ≥ .91
• Unfavorable / Favorable: Standardized factor loading λ ≥ .94
• Negative / Positive: Standardized factor loading λ ≥ .92

Confirmatory Factor Analysis (CFA)

When evaluated within larger structural measurement models comprising multiple latent variables (e.g., attitude toward the ad, fear of negative evaluation, behavioral intentions), the single-factor specification of the BAS-Yoon achieves exemplary model fit indices. Typical goodness-of-fit statistics include:

• Comparative Fit Index (CFI): > .99
• Tucker-Lewis Index (TLI): > .98
• Root Mean Square Error of Approximation (RMSEA): < .05 (with 90% confidence intervals ranging from .000 to .078)
• Standardized Root Mean Square Residual (SRMR): < .02

These empirical indices verify that the three items function as interchangeable yet complementary indicators of an underlying global behavioral evaluation parameter.

10. Instrument / Measurement Tool

The technical parameters and administration criteria for the Behavioral Attitude Scale (BAS-Yoon) are structured as follows:

• Test Type: Self-report psychometric rating scale / Semantic differential questionnaire.
• Administration Format: Paper-and-pencil questionnaire, computer-assisted web interview (CAWI), or mobile-responsive digital survey platform.
• Item Count: 3 items (bipolar adjective pairs).
• Target Population: Adolescents and adults (typically ages 18+) evaluating persuasive communication, health interventions, or promotional messaging.
• Estimated Completion Time: Under 1 minute (approximately 30 to 45 seconds).
• Response Scale: 7-point semantic differential scale (1 to 7), with numeric values mapped between bipolar adjective endpoints.
• Scoring Rules:
  • Each item is scored from 1 (most negative adjective: Bad, Unfavorable, Negative) to 7 (most positive adjective: Good, Favorable, Positive).
  • All items are keyed in a direct, positive direction; no reverse-scoring is required when formatted with the negative anchor at 1 and positive anchor at 7.
  • An overall index of attitude toward the focal behavior is computed by calculating the arithmetic mean of the three completed items: $$\text{Behavioral Attitude} = \frac{\text{Item 1} + \text{Item 2} + \text{Item 3}}{3}$$
  • Possible composite scores range from 1.00 to 7.00, with higher values reflecting a more positive, favorable, and constructive behavioral attitude toward the specified action.
