Abstract
Background. Medically unexplained symptoms affect between 4 and 20 percent of children and adolescents. Thirty to sixty percent of these children also experience mental health difficulties. Trials and reviews have focussed on physical gains in this population, often overlooking mental health outcomes. / Objectives. To use a systematic review methodology guided by the PRISMA checklist to: (i) Investigate the effectiveness of psychological interventions for mental health difficulties in children and adolescents with medically unexplained symptoms. (ii) Identify aspects of interventions associated with their success. / Methods. Randomised controlled studies investigating the impact of psychological interventions on mental health in children and adolescents with medically unexplained symptoms were included. Systematic searches of PsycINFO, MEDLINE and CINAHL were undertaken from inception to January 2018. Studies were appraised using the quality appraisal checklist (NICE, 2012). A qualitative synthesis of studies was completed. / Results. Eighteen studies were identified. Interventions targeting parental responses to illness and family communication appeared to have the best outcomes. / Conclusions. Psychological interventions may be effective in improving mental health outcomes within this population, however, evidence for the efficacy of these interventions is limited due to a high risk of bias within the majority of reviewed studies. Future research using rigorous methodology and non-CBT interventions is recommended. / Review registration number: CRD42016035817
