Reliability and Validity of questionnaires on SPSS

Validity Tests
Exploratory Factor Analysis (EFA)
ACP
Confirmatory Factor Analysis (CFA)
Convergent validity
Average Variance Extracted (AVE) GREATER THAN 0.50
Discriminant validity or divergent validity
Fornell and Larcker criterion (Higher diagonal correlation coefficients)
Heterotrait-monotrait ratio of correlations (HTMT) LESS THAN .85
Cross-loadings ≥.70
Reliability
📈 Cronbach alpha reliability ≥ 0.70
🔁 Test-retest reliability
👥 Interrater reliability
🔳Composite reliability

1) FC validity
Face validity: visual test
Content validity: Cohen's Kapp and Content Validity Ratio
