Abstract

Identifying factors that impact psychological treatment outcomes in older people with common mental health problems (CMHP) has important implications for supporting healthier and longer lives. The aim of the present study was to synthesise the evidence on predictors of psychological treatment outcomes in older people (aged 65+). PubMed, Scopus, Web of Science and PsycINFO were searched and 3929 articles were identified and screened, with 42 studies (N = 7978, M age = 68.9, SD age = 2.85) included: depression: k = 21, anxiety: k = 11, panic disorder: k = 3, mixed anxiety & depression: k = 3, PTSD: k = 2, various CMHP: k = 2, with CBT being the most common treatment (71%). The review identified 28 factors reported as significant predictors of treatment outcome in at least one study, across different domains: psychosocial (n = 9), clinical (n = 6), treatment-related (n = 6), socio-demographic (n = 4), neurobiological (n = 3). Homework completion was the most consistent predictor of positive treatment outcome. Baseline symptom severity was the most frequently studied significant predictor and across all conditions, with higher baseline symptom severity largely linked to worse treatment outcomes. No significant effects on treatment outcome were reported for gender, income and physical comorbidities. For a large majority of factors evidence was mixed or inconclusive. Further studies are required to identify factors affecting psychological treatment outcomes, which will be important for the development of personalised treatment approaches.
