Abstract

Objectives
Presentation of persistent physical symptoms (PPS) is associated with increased health care utilisation, yet clinical outcomes often remain suboptimal. This systematic review aimed to determine whether psychological interventions are effective for the management of PPS and if so, what are the features of the interventions and at what level of care are they delivered. The review also set out to establish which symptoms in those diagnosed with PPS can be effectively managed with psychological intervention.

Methods
Studies were included if they clearly reported a psychological intervention, specified the study sample as adults with a diagnosis of persistent physical symptoms, included a comparator, and as a minimum an outcome measure of somatic symptoms. Risk of bias was assessed using the EPHPP. Meta-analysis was conducted to estimate the overall effect of interventions on somatic symptoms (the primary outcome), anxiety and depression (secondary outcomes).

Results
Seventeen papers of varying quality indicated that psychological interventions can be effective for the management of somatic symptoms reported by individuals with PPS within a primary care setting. Psychological interventions were also found to be effective at reducing depression symptoms in individuals with PPS in twelve of the included studies. However, the meta-analysis results suggest that the psychological interventions utilised within eleven of the included studies did not significantly impact anxiety symptoms.

Conclusions
Psychological interventions have some success in managing somatic symptoms in PPS patients within primary care settings although their effects on other psychological symptoms is more mixed. The review highlights the importance of establishing a clearer diagnostic classification to inform treatment trajectories and the need for appropriate training and support within a multi-disciplinary team to enable the provision of such therapies.
