Measurement invariance of the Perceived Stress Scale across race, sex, and time, and differential impacts on cocaine use treatment outcomes.

ABSTRACT:

Introduction

To understand the influence of phenotypic characteristics, such as stress, on substance use treatment outcomes, measures must function equivalently across groups to allow for interpretable comparisons of effects. The present study evaluated measurement invariance of the Perceived Stress Scale (PSS) across race, sex, and time, examined its association with cocaine use disorder (CUD) treatment outcomes, and tested whether associations were moderated by race and/or sex.

Methods

Data from four clinical trials evaluating behavioral and/or pharmacological treatments for cocaine use were combined providing a total sample of 302 participants with DSM-IV cocaine abuse/dependence (57.6 % Black, 42.4 % White, 43.7 % females, M_age = 40.22 years, SD = 9.26).
