Evaluating the validity and reliability of the Chinese entrapment scale and the relationship to depression among men who have sex with men in Shanghai, China

Abstract Background Perception of entrapment can emerge when someone feels trapped in an aversive situation and incapable escape. Depression is closely related to the construct entrapment. In China, men who have sex with (MSM) a high prevalence depression; therefore, tool evaluate this population needed. We evaluated validity reliability Chinese version scale (ES) relationship depression among MSM Shanghai, China. Methods recruited 304 from four districts Participants completed health behavior questionnaires that included baseline information psychological measurements such as ES Patient Health Questionnaire (PHQ-9). The sample was randomly divided into two groups for exploratory factor analysis ( n = 143) confirmatory 161). Criterion tested explore correlation between PHQ-9 scores. internal consistency (Cronbach’s ? coefficient) split-half (Spearman-Brown coefficient). performed hierarchical regression determine variance explained predicting depressive symptoms after adjusting sociodemographic factors. Finally, receiver operator characteristic curve measure optimal cut-off value depression. Results Factor showed had one principal component, one-dimensional more acceptable model fit indices than two-dimensional model. coefficient scores 0.756 P < 0.01). Cronbach’s 0.970 Spearman-Brown 0.976. significantly predicted additional 45.1% controlling characteristics (? 0.689, 0.001). optimum 23, which sensitivity 70% specificity 85.4%. Conclusions has good be used perception MSM. findings confirmed association
