Distress in significant others of patients with chronic fatigue syndrome: a systematic review of the literature

Abstract

Purpose: To systematically review existing empirical research assessing levels and correlates of distress in significant others of patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).

Methods: Systematic searches in CINAHL, Web of Science and PsycINFO were conducted in August 2014. The search was repeated in January 2015 to check for newly published articles. Studies published in English with quantitative, qualitative or mixed designs exploring distress, poor subjective health, poor mental health, reduced quality of life and wellbeing, and symptoms of depression and anxiety in significant others (>18 years) of children and adults with CFS/ME were included. Quality appraisal of included studies was carried out. Quantitative and qualitative studies were summarized separately.

Results: Six articles met eligibility criteria. Two quantitative studies with significant others of adult patients, and one quantitative and two mixed-method studies with significant others of child patients showed moderate to high levels of distress. One qualitative study (adult patients) found minimal evidence of distress and that acceptance of CFS/ME was related to better adjustment. In the quantitative and mixed-method studies, significant others who attributed some level of responsibility for symptoms to the patient, or who were female, or whose partners had poorer mental health, had higher levels of distress.

Conclusions: The small number of studies to date, the contrary evidence from a qualitative study, and the limited data available on levels of distress in significant others of patients with CFS/ME means that our conclusion that distress levels are elevated is provisional. We recommend that future qualitative studies focus on this particular topic. Further longitudinal studies exploring correlates of distress within the context of a predictive theoretical model would be helpful.
