ObjectiveTo study relationships between Sense of Coherence (SOC), disability and mental and physical components of health-related quality of life (HRQoL) among rehabilitation patients.DesignSurvey.SettingRehabilitation centers in secondary care.ParticipantsA total of 975 from the Western Norway Health Region consented to participate and had valid data of the main outcome measures.InterventionsNot applicableMain outcome measuresSOC was measured with the Sense of Coherence questionnaire (SOC-13), disability with the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and HRQoL with the Short Form health survey (SF-36).ResultsMean scores (standard deviation) were 62.9 (12.3) for SOC-13, 30.8 (16.2) for WHODAS 2.0, 32.8 (9.6) for SF-36 physical component score and 43.6 (11.8) for SF-36 mental component score. Linear regression analysis showed that increased SOC score was associated with reduced disability scores in the following domains with estimated regression coefficients (95% confidence interval; CI) Cognition –0.20 (–0.32 to –0.08), Getting along –0.36 (–0.52 to –0.25), and Participation –0.23 (–0.36 to –0.11). The fit of two structural models with the association from SOC to HRQoL and disability or with disability as a mediator was better for the mental versus the physical component of HRQoL. High SOC increased the mental component of HRQoL, consistent for all diagnostic groups. For both models, good fit was reported for circulatory and less good fit for musculoskeletal diseases.ConclusionsThe results indicate that higher SOC decreases disability in mental domains. The effect of SOC on disability and HRQoL might vary between diagnostic groups. SOC could be a target in rehabilitation, especially among patients with circulatory diseases, but prospective studies are needed.
