Estructura factorial del cuestionario de apoyo social mos en ancianos colombianos con dolor crónico.

Perceived social support refers to one’s confidence that social support or resources are available if needed. It is related to health and quality of life in elderly, so it is recommended to be evaluated. The Social Support Survey MOS have been used but there is no evidence about its validity in Colombian ancient people with chronic pain. The aim of this study was to assess the factorial structure and reliability for the Social Support Survey MOS among a group of elderly people with chronic muskuloesqueletal pain; furthermore, differences between gender and married were investigated. 463 old people of different regions of Colombia were assessed with MOS and with a sociodemographic interview. Cronbach ranged between .86 y .98. Item correlations were higher than .60. The model of 4 correlated factors showed good fit (NFI= .997, AGFI= .996, RMR= .056 y GFI= .996), as shown by similar studies in other populations. Differences in social support perceived by gender and marital status were found. The results support the validity for the MOS to evaluate social support in ancient Colombian people with chronic muskuloesqueletal pain.
