Change in symptomatic burden and life satisfaction during short‐term psychotherapy: Focusing on the role of family income

Abstract

AbstractObjectiveThe article examines the role of family income on the relationship between change in symptomatic burden and change in life satisfaction during six sessions of naturalistically delivered individual psychotherapy.MethodFive hundred and thirty‐two clients receiving psychotherapy were assessed at baseline and on a session‐to‐session basis with the OQ‐30.2 and with a life satisfaction questionnaire. Data were analysed using a bivariate latent class model with structured residuals that included cross‐lagged and autoregressive components between residual scores at each time point. Adjusted family income and a binary low versus high‐income group variable were added as exogenous baseline covariates at different stages of the analyses.ResultsRegardless of income level, clients show improvement in psychological distress and life satisfaction as a function of time during treatment. Initial levels and improvement in life satisfaction are related to initial levels and improvement in psychological distress, and lower family income is related to slower decreases in psychological distress. When the whole sample is analysed, psychological distress and life satisfaction show reciprocal prospective relationships at the within‐person level. When models are estimated by income group, casual relationships at the within‐person level vary as a function of income.ConclusionFamily income level appears to play a significant role in the relationship between symptom improvement and life satisfaction during psychotherapy.
