Abstract

Abstract Background and aim Interpersonal problems are difficulties that an individual experiences in relating to others and are sources of subjective distress. The main purpose of this study was to examine reliability, validity, and exploratory factor analysis of a short form of the Inventory of Interpersonal Problems in an Iranian students. Materials and methods This is a psychometric study and analysis of the data involved mainly descriptive statistics. 647 volunteers (490 females, 434 males) from universities in Tehran were included in this study. All participants were asked to complete the Inventory of Interpersonal Problems (IIP-60), the Mental Health Inventory (MHI-28), the Self-Esteem Rating Scale (SERS), and the Emotional Intelligence Scale (EIS). The scale was validated with construct, convergent and discriminant validity. Its reliability was measured by internal consistency and test-retest reliability methods. Findings The results of explarotary factor analysis supported six factors for the IIP-60 as well as a single general factor of interpersonal problems. The convergent and discriminant validity of the IIP-60 were supported by an expected pattern of correlations between the scale and the measures of mental health, self-esteem, and emotional intelligence. Coefficient alpha estimates of internal reliability were between .82 and .93 for the IIP-60 subscales. Test-retest reliability of the IIP-60 was also calculated at the range of .65-.81. All correlations were statistically significant. Conclusion It can be concluded that the Inventory of Interpersonal Problems (IIP-60) is a valid and reliable scale to measure interpersonal problems.
