Role of common mental and physical disorders in partial disability around the world

Background Mental and physical disorders are associated with total disability, but their effects on days with partial disability (i.e. the ability to perform some, but not full-role, functioning in daily life) are not well understood. Aims To estimate individual (i.e. the consequences for an individual with a disorder) and societal effects (i.e. the avoidable partial disability in the society due to disorders) of mental and physical disorders on days with partial disability around the world. Method Respondents from 26 nationally representative samples (n=61 259, age 18+) were interviewed regarding mental and physical disorders, and day-to-day functioning. The Composite International Diagnostic Interview, version 3.0 (CIDI 3.0) was used to assess mental disorders; partial disability (expressed in full day equivalents) was assessed with the World Health Organization Disability Assessment Schedule in the CIDI 3.0. Results Respondents with disorders reported about 1.58 additional disability days per month compared with respondents without disorders. At the individual level, mental disorders (especially post-traumatic stress disorder, depression and bipolar disorder) yielded a higher number of days with disability than physical disorders. At the societal level, the population attributable risk proportion due to physical and mental disorders was 49% and 15% respectively. Conclusions Mental and physical disorders have a considerable impact on partial disability, at both the individual and at the societal level. Physical disorders yielded higher effects on partial disability than mental disorders.BristolMyers SquibbBristol-Myers SquibbEli Lilly CompanyEli Lilly CompanyGlaxoSmithKlineGlaxoSmithKlineJohnson & Johnson PharmaceuticalsJohnson & Johnson PharmaceuticalsOrthoMcNeil PharmaceuticalsOrtho-McNeil PharmaceuticalsPfizerPfizerSanofi-AventisSanofiAventisUS National Institute of Mental Health (NIMH) [R01MH070884]US National Institute of Mental Health (NIMH)Mental Health Burden StudyMental Health Burden Study [HHSN271200700030C]John D. and Catherine T.
