Assessment

Primary outcomes

An interpretable exploratory factor analysis (EFA) solution of the Autobiographical Editing Scale meeting all predefined criteria at baseline: (i) sampling adequacy with KMO >= 0.80 and significant Bartlett's test (p < 0.001); (ii) number of factors determined by parallel analysis and MAP; (iii) primary loadings >= 0.40 with cross-loadings < 0.30; (iv) item communalities >= 0.30; and (v) cumulative variance explained >= 50% for the retained factors.

Key secondary outcomes

Internal consistency: McDonalds omega > 0.80 (Cronbach s alpha also to be reported)
Testretest reliability: ICC(2,1) > 0.70 over 2~4 weeks
Convergent / discriminant validity: Preregistered directional hypotheses
Item analysis: acceptable item information and thresholds; itemtotal r > 0.30
