Psychometric properties of the Arabic versions of the long (27 items) and short (13 items) forms of the interpersonal mindfulness scale (IMS)

Background There is a lack of measures and data on interpersonal mindfulness from non-Western cultures, which can hinder advances in our understanding of the construct, its conceptual representation, and its effects on human connection and relationships within different cultural settings. To fill this gap and help spark future research in this area in the Arab world, the current study aimed to examine the psychometric properties of an Arabic translation of the 27-item and the 13-item versions of the interpersonal Mindfulness Scale (IMS) in a sample of Arabic-speaking adolescents from the general population.Methods A web-based survey was conducted in a sample of 527 Lebanese community adolescents (Mean age = 15.73 +/- 1.81 years; 56% females). The IMS was translated from English into Arabic using the forward-backward translation method. Participants completed the long and short forms of the IMS, as well as the Buss-Perry Aggression Questionnaire-Short Form (BPAQ-SF), and the 5-item Brief Irritability Test.Results Confirmatory factor analyses provided support to the four-factor structure of both the 27-item and the 13-item IMS (i.e., Presence, Awareness of Self and Others, Nonjudgmental Acceptance, and Nonreactivity). The original and the short form versions of the IMS yielded excellent internal consistency in our sample, with a Cronbach's alpha coefficients of 0.95 and 0.90, and McDonald's omega coefficients of 0.95 and 0.90, respectively. Multigroup comparisons suggested the factorial invariance of the Arabic 27-item and 13-item IMS between male and female participants at the metric, configural, and scalar levels. Finally, the concurrent validity of both full-length and short form of the IMS appeared to be good and comparable, as attested by patterns of correlations in expected directions with outcome variables (i.e., aggression, anger, hostility, and irritability).Conclusion The present findings provide support for the good psychometric qualities of the Arabic translation of the IMS in both long and short forms, suggesting that these scales are suitable for use to measure interpersonal mindfulness in Arabic-speaking youth, at least in Lebanon. We expect that the IMS, in particular its shortest form, will prompt more systematic investigation of interpersonal mindfulness in the Arabic-speaking populations, especially with regard to enhancing healthy communications with others and building effective social relationships.
