Scholarcy highlights
- A structural equation methodology is used to assess the reliability and validity of expectancy-value and semantic differential measures of attitude toward the act of donating blood
- Hypotheses as to the internal consistency and the convergent, concurrent, discriminant, predictive, and nomological validities of responses are tested in the context of a quasi-experiment performed on 284 students, faculty, and staff
- Semantic differential attitudes are found to exist as unidimensional responses while expectancy-value attitudes are found to occur as multidimensional reactions
- Both operationalizations achieve convergent, concurrent, discriminant, and predictive validity, the nomological validity of attitude is brought into question
- The findings are interpreted from attitude, learning, and attribution theory arguments
