AbstractWe conducted two studies to examine the psychometric properties of the Body Investment Scale (BIS; Orbach & Mikulincer, 1998) in U.S. adolescent samples. The BIS was designed to assess bodily experiences that are associated with suicide-related behaviors. In Study 1, confirmatory factor analysis (CFA) with data from a combined sample of 204 high school adolescents (83 boys, 121 girls) and 197 psychiatric inpatient (101 boys, 96 girls) adolescents provided moderate support for the oblique four-factor solution: Body Feelings (rho=.86, 95% CI=.83-.89), Body Touch (rho=.71, 95% CI=.65-.76), Body Care (rho=.78, 95% CI=.71-.81), and Body Protection (rho=.78, 95% CI=.73-.82); robust comparative fit index=.88 and the robust Tucker Lewis Index=.83. The second-order factor model also provided moderate fit to the data. In Study 2, results of the CFA with data from adolescent psychiatric inpatients (N=205; 101 boys, 104 girls) provided additional support for the four-factor solution. In addition, results of the receiver operating characteristic and logistic regression analyses showed that scores on the Body Feelings and Body Protection scales were most useful in differentiating the responses of suicidal and nonsuicidal adolescents, all Cohen's d values >.30. The study also examined associations between scores on the BIS scales and the validation self-report measures of hopelessness, suicide-related behavior, and reasons for living.Copyright 2009 Wiley Periodicals, Inc.
