Sense of coherence -: A mediator between disability and handicap?

Background: The aim of this study was first to analyze the associations between disability and handicap and Antonovsky's concept of sense of coherence (SOC); secondly, to find out how the SOC concept could be integrated in the WHO model of impairments, disabilities, and handicaps (ICIDH). Methods: Data from two studies were used: one on patients with rheumatoid arthritis, one on severely injured accident victims. Objective measures of the illness or the injury were conceptualized as indicator variables for disability, whereas variables related to the patients' subjective judgement were conceptualized as indicator variables for handicap. Correlations were calculated between both sets of variables and the SOC scale total score. Results: SOC showed no significant correlation with 'disability variables' (rheumatoid arthritis: HAQ, SF36 physical functioning; accidental injuries: ISS, GCS). However, significant correlations were found between SOC and all 'handicap variables' (rheumatoid arthritis: HAD, SF36 social functioning; accidental injuries: CAPS-2, IES, SCL-90-R depression subscale). Conclusions: SOC is related to the psychosocial effects of health problems. It may be understood as a mediator between disability and handicap. Prospective studies are needed to clarify whether the SOC scale can be used as an outcome predictor with regard to psychosocial adaptation, in acute as well as in chronic health problems.
