abstract="OBJECTIVE: This study evaluated the factor structure, internal consistency reliability, construct and criterion validity, and measurement invariance of the Interpersonal Needs Questionnaire (INQ) among adolescents. METHOD: Participants (N = 539) included three distinct samples of youth drawn from two outpatient psychology clinics and an inpatient psychiatric unit. The combined sample was 63.3% female and had a mean age of 14.95 years (SD = 1.31 years). All participants completed the INQ as well as measures of depressive symptoms and suicide ideation. RESULTS: Confirmatory factor analyses indicated that the removal of three items from the thwarted belongingness subscale of the INQ was needed to achieve acceptable model fit. The resulting combined 12-item scale demonstrated good factor structure, internal consistency reliability, construct validity, and criterion validity. The modified 12-item INQ also demonstrated scalar invariance across subgroups defined by sex, race, and age. CONCLUSIONS: Findings support the use of this reduced 12-item version of the INQ among adolescents. Youth may have difficulty accurately responding to changes in item valence; thus, future research with youth should consider using a 12-item version of the INQ that avoids valence changes within subscales.<p /><p>Language: en</p>",
