Background Non-suicidal self-injury (NSSI) is a serious public health problem prevalent among adolescents and young adults. The present study examines the factor structure, internal consistency, and validity of the Persian version of the Inventory of Statements About Self-injury (ISAS), a self-report measure designed to comprehensively assess non-suicidal self-injury (NSSI). Methods A total of 655 Iranian school-attending adolescents completed study measures online, and 246 youth (37.70 %) (M age = 15.38, SD ± 0.50; 53 % female) reported a history of NSSI at least once during their lifetime. Results Confirmatory factor analysis supported the proposed two-factor model of ISAS (i.e., Interpersonal and Intrapersonal dimensions), which were internally consistent and yielded direct associations with converging correlates (e.g., depression, anxiety, irritability, and anger). Conclusions Findings indicated that the Persian version of the ISAS has sound psychometric properties and is a valid and reliable self-report measure of NSSI.
Background: Cognitive impairment is a chronic and disabling manifestation of schizophrenia. Objectives: This before-after study was conducted to examine the effect of a short course computer-assisted cognitive remediation on improving cognitive functions of patients with schizophrenia. Materials and Methods: Twenty patients with schizophrenia were enrolled into the study. The intervention consisted of 10 onehour sessions held 2-3 times a week, using the Cogpack software that includes tasks to improve attention, memory, and executive function. The patients' cognitive functioning was assessed before and after the remediation, using tests in the CANTAB battery, including stop signal task (SST) and choice reaction time (CRT) to assess attention levels, pattern recognition memory (PRM) and Paired associate learning (PAL) to examine memory, and stocking of Cambridge (SOC) and intra-extra dimensional task (IED) to evaluate executive function. Results: IED and SOC revealed a statistically significant improvement in executive function after the intervention. PAL revealed a significant improvement in memory functioning in most aspects after the intervention, while PRM did not. CRT showed a significant improvement in some aspects of attention and concentration after the intervention, while SST did not. Conclusions: This before-after study revealed that a relatively short course of a computer-assisted cognitive remediation can be applied to improve several aspects of cognitive functioning in patients with schizophrenia. A randomized controlled trial is required to establish the effectiveness of the intervention.
Given the prevalence and consequences of the nonsuicidal self-injury disorder (NSSID) among adolescents, this study aimed to analyze the effectiveness of emotion regulation therapy (ERT) among adolescents with NSSID. The present study is an after-trial, mixed-method intervention design. Six participants completed questionnaires at baseline, during their treatment, and follow-up. In-depth interviews were made after the intervention. The quantitative findings were consistent with the pattern of the qualitative findings that prominently supported the treatment efficiency concerning the difficulties in emotion regulation. The research findings indicated that ERT had a positive effect on adolescents with NSSID.
