Abstract
Objective: to design and validate the Violence Risk Prediction and Assessment Scale (EPERV-55) in persons with severe mental disorder (SMD) hospitalized in medium and long-stay units.
Method: an EPERV-55 questionnaire was prepared, including 55 items, based on the literature reviewed and the knowledge by the research team about different tools for violence prediction and evaluation in SMD. Clinical data on risk prediction and management were incorporated, including the NANDA/NOC taxonomy. For construction validity, data were collected from patients hospitalized in Mental Health Units of the Hospital Parc Sanitari Sant Joan de Déu (Barcelona). The internal consistency of the scale was assessed with Cronbach’s Alpha Coefficient. Convergent validity was evaluated through Spearman’s Rho Correlation Coefficient, comparing EPERV-55 vs. the Violence Risk Scale by Plutchik. Mann-Whitney’s U Test was used in order to measure sensitivity and specificity; analyses were conducted with the R 2.13 and SPSS 19 statistic programs.
Results: the study included 177 subjects. The model presented 0.92 in Cronbach’s alpha. Test-retest accuracy was good in 23 items of the scale, and moderate in 32 items. Convergent validity was significant with the EPERV-55-RV scales (Spearman’s Correlation: -0.348 and -0.458 respectively; p < 0.001). Regarding sensitivity and specificity, significant differences were observed in Overall Violence (p< 0.004) and Hetero-aggressive Violence (p< 0.005). The Roc Curve index was significant in Hetero-aggressive Violence, against objects, and general.
Conclusions: the EPERV-55 scale is a valid tool to evaluate and predict the risk of violence in persons with SMD hospitalized in medium and long-stay units.
