Reliability and construct validity of the Japanese version of the interpersonal relationship inventory

The present study examined the psychometric characteristics of the three network function subscales (Social Support, Conflict, and Reciprocity) in the Japanese version of the Interpersonal Relationship Inventory. Data from Japanese college students (250 women and 218 men) were analyzed to estimate internal consistency (alphas = .93-.96) and test-retest reliability (rs = .69-.74). To assess construct validity, correlations between scores on the inventory and measures of social support, loneliness, and stress were performed. Results indicated that the Japanese version of the inventory was valid and reliable.
