Applicability of capacity of sexual self-defense assessment scale in psychiatric patients without mental retardation / 法医学杂志

ABSTRACT

OBJECTIVE@#To explore the applicability of Capacity of Sexual Self-defense Assessment Scale (CSSAS) in psychiatric patients without mental retardation.@*METHODS@#Eighty-seven cases required for assessment of the capacity of sexual self-defense were collected and evaluated by trained professionals according to CSSAS, and the results were compared to the experts' opinions.@*RESULTS@#The scores of three grades of capacity of sexual self-defense (none, limited and whole) were 5.97 +/- 5.83, 32.22 +/- 10.15 and 61.60 +/- 13.02, respectively, which were statistically significant among them (P < 0.01). The correlation coefficients between items and total score were 0.59 to 0.91, the Cronbach's alpha value was 0.96, the spilt half Cronbach's alpha value were 0.94 and 0.91, respectively, and the relation coefficient between them was 0.94. According to the original cut off scores, the Kappa value between scale results and experts' opinions was 0.32 (P < 0.01). By redefining the cut off scores, the Kappa value was improved to 0.84 (P < 0.01). Two factors were extracted by means of the factor analysis. The explanation rates of variance were 46.15% and 28.93%, respectively. The accuracy of retrospective cumulative square was 94.30%.@*CONCLUSION@#The CSSAS could be applied in the psychiatric expertise of the capacity of sexual self-defense in psychiatric patients without mental retardation; however, the cut off scores and the factor weight should be redefined.
