Life attitude scale is a screening tool used to predict suicide behavior of children and teenagers. Indicated in international literature, the scale possesses good reliability and validity, which however have not been verified in Taiwan. This research thus aimed to examine the reliability and validity of life attitude scale in Chinese version. By convenience sampling approach, 1492 students from senior high schools and vocational schools in Taipei were recruited. These subjects were requested to answer a structured questionnaire, which includes personal information, Beck hopelessness scale (BHS), positive and negative suicide ideation inventory (PANSI), cognitive triad inventory (CTI-C), suicidal risk scale and children’s depression inventory (CDI). Collected data were statistically analyzed including descriptive statistics, correlation analysis, independent samples t-test and confirmatory factor analysis to examine the reliability and validity of life attitude scale. The research results showed that the Chinese version of life attitude scale has 0.9 Cronbach’s α value and 0.99 expert’s validity CVI value, and the model fit indexes of the confirmatory factor analysis are χ2(33)= 129.9, p=.00, CFI=0.99, GFI=0.99, NC(χ2 /df)=3.94 and RMR=0.06, suggesting there are acceptable indexes of reliability and validity. This scale and BHS (r=.67), negative suicidal idea (PANSI-NSI) (r=.54), CTI-C (r= -.72), positive idea (PANSI-PI) (r= -.57), CDI (r= .67) and suicidal risk scale (r=.56) were all found statistically significant. The results indicated good reliability and validity of the Chinese version of life attitude scale. This research is in the hope of establishing such scale with good reliability and validity that can be used at schools and medical care institutions for screening teenagers at high risk of committing suicide. Guidance and assistance and treatment can be given early so as to effectively prevent suicide.
