Schizophrenic patients on violent severity, violent severity self-managementAbstract
This study employed a quasi-experimental design to examine the effectiveness of a self-management program on violence severity among patients with schizophrenia. The participants were patients with schizophrenia at high risk of violence (Serious Mental Illness with High Risk to Violence: SMI-V) admitted to the psychosocial department at Khamkuaenkaew Hospital.
A total of 40 participants were equally assigned to an experimental group (n = 20) and a control group (n = 20). The experimental group received a self-management program for violent behavior over a period of 2 weeks, consisting of five sessions.The research instruments included: (1) a self-management program based on the concept proposed by Ryan and Sawin (2009), (2) a demographic data form, (3) the Prasri Violence Severity Scale (PVSS), and (4) the Brief Psychiatric Rating Scale (BPRS). The intervention was validated by three experts, yielding a content validity index (CVI) of 0.90. Inter-rater reliability was 0.88, and the intraclass correlation coefficient (ICC) was 0.80.Data were analyzed using descriptive statistics (mean and standard deviation) and two-way ANOVA.
The results indicated that the self-management program significantly reduced violence severity scores in the experimental group compared to the control group (p < .05). The mean violence severity scores in the experimental group decreased at 2 weeks (3.65 ± 1.25) and further decreased at 4 weeks post-intervention (1.55 ± 2.27).
In conclusion, the self-management program effectively reduced the severity of violence risk among patients with schizophrenia.
