Effects of a pain self-management intervention combining written and video elements on health-related quality of life among people with different levels of education.

Combining written and video material could increase the impact of health education for people with less education, but more evidence is needed about the impact of combined materials in different formats, especially in the context of chronic pain self-management. This study tested the impact of combining written information about self-managing chronic joint pain, which used language at a high reading level, with a DVD containing narrative video material presented directly by patients, using language at a lower reading level. Physical and mental health-related quality of life (36-Item Short Form Health Survey) was measured among 107 men with hemophilia before and 6 months after being randomly assigned to receive an information booklet alone or the booklet plus the DVD. Analysis of covariance was used to compare health outcomes between randomized groups at follow-up, using the baseline measures as covariates, with stratified analyses for groups with different levels of education. The DVD significantly improved mental health-related quality of life among those with only high school education. Video material could therefore supplement written information to increase its impact on groups with less education, and combined interventions of this type could help to achieve health benefits for disadvantaged groups who are most in need of intervention.
