    Study Notes

    Measuring Reliability, Participative Leadership, and Construct Validity

    • Reliability refers to the consistency of an item, scale, or instrument when administered at different times, locations, or populations.
    • A reliability estimate value (range 0-1) indicates the proportion of variability in the measure attributable to the true score.
    • Participative leadership involves a managerial style that encourages input from employees on company decisions.
    • Construct validity assesses the logic of items that make up measures of social concepts and requires a clear theoretical basis and measurable indicators.
    • Criterion-related validity examines whether a measure relates to other constructs as expected, including predictive, convergent, and discriminant validity.
    • A self-report measure of clinicians' orientation toward integrative medicine involved developing and revising a questionnaire to reflect key domains of integrative medicine.
    • The questionnaire's reliability was assessed using Cronbach's alpha, and its construct validity was evaluated using a relational approach.
    • The dimensionality of a construct refers to whether it is one-dimensional or has multiple dimensions/factors, such as job satisfaction or safety culture.
    • Factor analysis is used to assess the dimensionality of a construct by uncovering the underlying structure of a set of variables and identifying clusters of highly correlated items.
    • Methods for estimating reliability include split-half reliability and test-retest reliability, which looks at inter-item correlations and can be established in experimental and quasi designs.
    • Establishing construct validity is challenging and involves assessing face and content validity, as well as using a relational approach.
    • Relational approaches in construct validity include examining associations between scores and other relevant items or constructs to assess the measure's validity.
