Structural validity of the questionnaire was assessed via exploratory factor analysis (EFA), while reliability was evaluated through internal consistency (Cronbach\u2019s alpha) and split-half reliability.

EFA revealed a six-dimensional structure that explained 69% of the variance. The questionnaire demonstrated strong reliability (Cronbach\u2019s alpha\u2009=\u20090.889, split-half\u2009=\u20090.780).
