Reliability Analyses for the ADSI: Test-Retest and Internal Consistency

Pages 247-253 | Published online: 11 Jul 2012
 

Abstract

Objective: This article reports on two separate studies of reliability of the Adolescent Domain Screening Inventory (ADSI), test-retest and internal consistency analyses. The ADSI has shown adequate validity, although reliability has not been established. Methods: Study 1: Students were recruited from two undergraduate courses (N = 29). Participants were administered the ADSI twice, 14 days apart. Data were analyzed using SPSS software; correlations were computed for all four domains and the total score. Study 2: A secondary data analysis of 6,661 cases was conducted using the Scale – Reliability Analysis function in SPSS to determine the Cronbach alpha for each domain in the ADSI. Results: Study 1: Correlations were as follow: Total – r = .95; school – r = .84; family – r = .85; community – r = .80; and individual/peer – r = .95. Study 2: Alphas were as follow: .53 – school, .62 – family, .55 – community, and .82 – individual/peer. Conclusions: Together, these studies provide evidence for the reliability of the ADSI.
