Abstract
Up to 30% of the population in Western countries suffer from chronic pain.
The treatment of chronic pain causes medical and socioeconomic problems.
Guided self-help (GSH) might be an effective supplementary treatment,
however, the size of this effect is unclear. This meta-analysis quantifies
the effect of GSH on chronic pain. A systematic literature search was
conducted using PubMed, Cochrane, Psyndex, Psycinfo and Scopus. Studies
that investigated GSH in chronic pain conditions (children and adults) were
included. Disability, quality of life and pain severity were defined as
main outcomes. We conducted random effects models to calculate standardized
mean differences (SMDs). By applying mixed models and subgroup analyses, we
examined the moderating effects of sample characteristics (age; pain
region), GSH format (online; face-to-face contact) and study
characteristics (study quality; control condition). We identified 16
eligible studies, including 739 subjects. Between-group analyses resulted
in a medium, but heterogeneous effect size for pain severity (SMD = 0.51;
CI95 : 0.21, 0.81). After excluding two samples suggesting small study
bias, the effect on pain severity was small but homogeneous (SMD = 0.34;
CI95 : 0.13, 0.54). We found a small effect size for disability (SMD =
0.30; CI95 : 0.10, 0.50). The pooled effect size for quality of life did
not reach significance (SMD = 0.24; CI95 : -0.07, 0.54). We conclude that
GSH has a small but robust effect on pain severity and disability in
chronic pain patients. This applies to various GSH formats and patient
populations. It seems reasonable to integrate GSH into clinical practice as
a supplemental treatment option. WHAT DOES THIS REVIEW ADD?: The present
meta-analytic review found small but robust effects of guided self-help
interventions for the treatment of chronic pain.
