Abstract :
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 (x2 = 131.69; P < 0.001; df = 56; x2/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 reliabilityamongthe opioid
and alcohol-abusing population in Iran.
