Function of Nonsuicidal Self-Injury Among Iranian University Students: A Factor Structure Analysis

Maryam Gholamrezaei et al. Psychol Rep. .

Abstract

Emerging non-Western studies indicate new patterns in the functionality of nonsuicidal self-injury (NSSI) warranting further investigation in different cultures. The current study aims to investigate the function (etiology and underlying mechanism) of NSSI among a sample of university students in Tehran, Iran, using the Inventory of Statements About Self-Injury (ISAS). The ISAS was administered to 63 students who self-injured (52.4% female; Mage = 22.15). An exploratory factor analysis using the Bayesian estimation method was conducted. A three-factor model of NSSI functions emerged including an intrapersonal factor representing within-self functions (e.g., self-punishment); a social identification factor consisting of functions establishing a sense of self/identity (e.g., peer bonding); and a communication factor representing an influencing/communicating functionality (e.g., marking distress). Intrapersonal and social identification factors were associated with greater severity of NSSI method and increased anxiety. Findings support the use of the ISAS among an Iranian sample and revealed additional patterns beyond the commonly referenced two-factor model (intrapersonal and interpersonal functions) in a culturally novel sample. The results are situated within the sample's sociocultural context.

Keywords: Iran; Nonsuicidal self-injury (NSSI); function; inventory of statements about self-injury (ISAS); university students.
