HAASE, Vitor Geraldi et al. Assessment of psychosocial functioning in multiple sclerosis: psychometric characteristics of four self-report measures. Arq. Neuro-Psiquiatr. [online]. 2004, vol.62, n.2a, pp. 282-290. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2004000200017.

Major and subsyndromic depression are highly prevalent in multiple sclerosis(MS). Assessment of psychosocial functioning in MS requires sound psychometric instruments. Self-report measures offer several advantages, but a valid and reliable depression self-report diagnostic measure is lacking. Beck Depression Inventory (BDI) and General Health Questionnaire (GHQ) have been validated and widely used in Brazilian neuropsychological context. BDI use in MS may confound depressive symptoms with somatic disease manifestations. We examined the psychometric properties of the BDI, QSG and two additional self-report measures of fatigue (CPF-MS) and self-efficacy (MSSE). All scales presented excellent reliability coefficients. BDI and GHG discrimanted MS from control participants. Intercorrelations were observed between depression, general mental health, fatigue and self-efficacy scores, but not between these and traditional indices of neurological impairment such as AI and EDSS. Depressive symptoms and fatigue may represent a different dimension of neurological impairment, unrelated to sensory and motor deficits. Self-report scales are useful in diagnosing subsyndromic distress symptoms in a MS sample.
