Assessing the Reliability of Scores Produced by the Substance Abuse Subtle Screening Inventory (SASSI) by Joshua Woodson The fundamental principle that reliability is a property of scores and not of instruments provides the foundation of a meta-analytic technique called reliability generalization (RG). RG studies characterize the reliability of scores generated by a given instrument and identify methodological and sample characteristics that contribute to the variability in the reliability of

Bivariate correlations revealed strong, positive correlations between SASSI score reliability and score variability of the Subtle Attributes (r = .877, p < .05) and Family History (r = .892, p < .05) subscales and between score reliability and ethnicity for both the Family History (r = .683, p < .05) and Tendency to Involvement in Correctional Setting (r = .76, p < .05) subscales.
