*Scores higher than 0.9 may indicate redundancy in the scale questions 

Construct Validity

Schizophrenia: (Chiu et al., 2004)

  • Exploratory factor analysis identified two factors that accounted for 69.0% of the total variance.

Content Validity

“The content validity of items was endorsed by a panel of 8 rehabilitation professionals with 75% to 100% agreement. From the results of this panel, Chiu and Tsang (2004) concluded that all 10 items in Chinese General Self-efficacy Scales showed good to excellent content validity (p.160).”
