Validation of the Quality of Relationships Inventory in a Peruvian Sample of Adolescents: Associations to Peer Attachment

Research concerning adolescent peer relations and peer attachment is scarce, and more so in Spanish-speaking populations. The aims of this study were twofold: (a) to adapt the Quality of Relationships Inventory to Spanish and (b) to assess its psychometric properties in the context of peer relations in a sample of N = 269 Peruvian adolescents. Internal consistency was adequate (ranging from α = .733 to .826). The factor structure of the instrument was assessed by means of confirmatory factor analysis (CFA), RMSEA = .06, CFI = .83, and multidimensional scaling (MDS), general non-metric stress (2D) =.33. Convergent validity was explored by analyzing the associations between the QRI subscales and the peer subscales of the Inventory of Parent and Peer Attachment (correlations ranged from r = .37, p < .01 to r = .61, p < .01) and discriminant validity by exploring the associations between the QRI subscales and both internalizing and externalizing symptoms (correlations ranged from r = .27, p < .01 to r = .35, p < .01). Results showed that the QRI on its Spanish version is a reliable tool for the assessment of the quality of peer relationships within a Peruvian context when taking some considerations into account regarding the conflict scale.status: publishe
