Abstract
OBJECTIVE: High levels of depression and anxiety are experienced alongside Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). Psychological causal and maintenance factors are not well-understood. Perfectionism is a multifactorial, transdiagnostic risk factor for various physical and mental health conditions. This systematic review assesses the association between perfectionism and depression and/or anxiety in people with CFS/ME. METHOD: Systematic literature searches used a combination of terms for 'perfectionism', 'depression', 'anxiety' and 'CFS/ME'. Peer-reviewed English-language papers reporting quantitative data regarding the relationship between perfectionism and depression and/or anxiety in adults (aged 18-65 years) with a clinical diagnosis of CFS/ME were included. Screening, selection and assessment of risk of bias was completed independently by two authors. Bivariate and multivariate associations between perfectionism and anxiety and depression were extracted. Data were synthesised narratively. RESULTS: Seven studies, reported in eight papers, were included. Seven examined the relationship between perfectionism and depression. Moderate-strong significant positive associations were found between depression and maladaptive perfectionism (r = 0.42 to .48, p < .01), and its component factors of concern over mistakes (r = 0.40 to .60, p < .01) and doubts about actions (r = 0.51 to .60, p < .01). Methodological limitations included sample size justification and selection, psychometric measures, and control of potential confounders. CONCLUSION: Maladaptive perfectionism is consistently associated with depression in patients with CFS/ME. The relationship between perfectionism and anxiety is under-researched. Corroboration is required from longitudinal, cross-cultural studies. Clinical understanding may be increased through examining the interplay between maladaptive perfectionism, depression and anxiety and the physical and cognitive symptoms of CFS/ME.
