Psychometric Properties of the Inventory of Statements about Self-Injury (ISAS) in Iranian Opioid and Alcohol Abusers

Background: Non-suicidal self-injury (NSSI) is one of the most dangerous behaviors linked to substance abuse. The Inventory of Statements About Self-Injury (ISAS) has been developed to better understanding the factors associated with the onset and maintenance of NSSI behaviors. Objective: The ISAS was translated into the Persian language to study its psychometric properties in Iranian population of opioid and alcohol abusers. Methods: This is a psychometric study investigating opioid and alcohol abusers in Iran, including those residing in addiction rehabilitation camps, prisons, hospitals, and addiction treatment clinics dispensing methadone in 2017. The sample size of this study was 470. The subjects completed the Inventory of Statements About Self-Injury, Barrat Impulsiveness Scale (BIS), and the Distress Tolerance Scale (DTS). Results: The test-retest results were estimated for two weeks using the Intra-class Correlation Coefficient (ICC). The absolute reliability was determined to be 2.62. There was a significant correlation between convergent and divergent instruments. The results of the exploratory factor analysis on 235 individuals in the sample showed all subscales of the inventory measure a single factor in the Iranian population. The total Cronbach�s alpha coefficient for this subscale was 0.93. Also, the results of confirmatory factor analyses on the rest of the sample (235), after applying the AMOS software suggestions to improve the model, showed this inventory was a good indicator for this population (�2 = 131.69; P < 0.001; df = 56; �2/df = 2.35; CFI = 0.97; RMSEA = 0.76; GFI = 0.92). Conclusions: The Persian version of the Inventory of Statements About Self-Injury has high validity and reliability among the opioid and alcohol-abusing population in Iran.

Psychometric Properties of the Pornography Craving Questionnaire (PCQ) in Iran

Objectives: Addiction to pornography is one of the most important behavioral addictions among Iranian youth. The purpose of this study was to develop and validate a measurement scale of �cravings for pornography� Iran. Methods: This Psychometric study was conducted on a 234 general Iranian population sample in 2017 with a random sampling method. In this study, the psychometric properties of the Persian version of the Pornography Craving Questionnaire were evaluated. Data were analyzed by exploratory factor analysis using SPSS version 23. The questionnaire was administered online (Telegram application and email). Results: The age range of 234 study participants was 13 to 51 years (mean = 29.7); 97 females (41.5) and 135 males (57.7). To determine this questionnaire�s cut-off value, we divided into three categories of low or no craving (12 - 36), average (36 - 60), and high (60 - 84). The result of exploratory factor analysis for these questions identified two factors (Psychological reactions and Desire). Cronbach�s alpha was 0.8. Conclusions: According to the results of this study, the Persian version of the �the pornography craving questionnaire� has sufficient reliability and validity in Iranian society.
