Validation of the Concise Chinese Level of Expressed Emotion Scale

摘要

Expressed emotion (EE), a strong predictor of relapse of schizophrenia, has significant clinical implications. The study aims to validate a concise Chinese version of the 60-item Level of Expressed Emotion Scale (LEE). A questionnaire survey was conducted with 188 schizophrenic patients. The battery of validation scales included Hospital Anxiety and Depression Scale (HADS) and 12-item Short Form Health Survey (SF-12). Exploratory factor analysis revealed a 3-factor, 12-item solution. Factor explication named the three factors Criticism, Over-Involvement, and Hostility. Cronbach's alpha of the whole scale was .84 and the three sub-scales were .75 to .77. Regarding convergence and divergence construct validity, the Concise Chinese LEE Scale has significant positive correlations with the anxiety and depression scores of HADS (r = .37 and .21, respectively; p < .01); significant negative correlation with the mental component score of SF-12 (r =a??a??0.27; p < .01); and insignificant correlation with the physical component score of SF-12 (r =a??a??0.02). The Concise Chinese LEE Scale showed good psychometric properties in internal consistence and convergence/divergence construct validity. The three-factor structure is coherent with the original conceptualization of high EE. Further validation of the scale is worth pursuing, especially on predictive validity.View full textDownload full textKeywordsexpressed emotion, schizophrenia, Chinese, factor analysis, scaleRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15332985.2011.570653
