Application of psychiatric assessment scale of cognitive and volition capacity in violent crimes / 中华行为医学与脑科学杂志

ABSTRACT

ObjectiveTo explore the feasibility of psychiatric assessment scale of cognitive and volition capacity(PASCVC) in violent crimes.MethodsThe PASCVC,criminal responsibility rating scale for violence(CRRSV) and criminal responsibility rating scale(CRRS)were used respectively in 244 forensic psychiatric cases.All cases were classified by the judicial surveyor into three grades including complete lost,partial lost and normal,the results were compared with expert's opinions.Results①PASCVC was composed of two subscalescognitive capacity and volition capacity.There were significant differences in rating average score of three groups (complete lost,partial lost and normal) of total scale,cognitive capacity and volition capacity subscales were 9.96±7.53,69.15±10.290,101.16±6.034;20.29±4.971,37.13±5.388,2.55±2.612;18.32±2.595,30.07±4.595,48.34±4.147 respectively and there were significant differences between them.②27 items had good correlation with the scale(r=0.157~0.915).③According to the reference demarcation points of scale,12 criteria were carried out by using stepwise discriminant analysis.The accuracy of retrospective cumulative square was 97.1%.④Total scale and subscales consistency of three demarcation point grading assessment results were consistent with expert's opinions,the Kappa values were 0.925,0.848 and 0.930 respectively (P<0.01);PASCVC consistency with CRRSV and CRRS,the correlation coefficients were 0.952 and 0.961 respectively (P<0.01),the Kappa values were 0.830 and 0.881 respectively (P<0.01).Conclusion The PASCVC is feasible to be used in violent crimes.
