          Abstract

          Abstract Objective To assess the psychometric properties of the Medical Outcomes Study Social Support Survey (MOS-SSS) considering a sample of elderly users of the primary healthcare facilities of Ribeirão Preto, state of São Paulo, southeast Brazil. Methods The MOS-SSS is a widely used measurement of social support in different contexts, consisting of 19 items with answer categories that range on a 7-point rating scale. Data collection regarding the psychometric properties of the MOS-SSS was performed in a stratified sample of elderly users of primary healthcare facilities of Ribeirão Preto. Data were collected at five district basic health units located in the city through face-to-face interviews. Polychoric correlation matrix and exploratory (EFA) and confirmatory (CFA) factor analyses were performed. Results A total of 357 elderly subjects aged 60 years or older participated in the study (62.7% females). According to the polychoric correlation matrix, higher coefficients of correlation (> 0.90) were detected among 12 pairs of items and grouped into four factors, as suggested for EFA. The results of the CFA confirmed the construct validity of the four-factor structure of the MOS-SSS when applied to our sample, as well as the stability of this model in distinct subsamples. Conclusion The four-factor structure of the MOS-SSS was found to be suitable and presented adequate construct validity for the assessment of social support in elderly users of primary healthcare facilities.

          Resumo Objetivo Avaliar as propriedades psicométricas do Medical Outcomes Study Social Support Survey (MOS-SSS), considerando uma amostra de idosos usuários das unidades de atenção primária à saúde de Ribeirão Preto, São Paulo, sudeste do Brasil. Métodos O MOS-SSS é uma escala para investigação do suporte social amplamente utilizada e aplicável a diferentes contextos. A escala é composta por 19 itens com categorias de respostas que variam em uma escala de 7 pontos. A coleta de dados foi realizada em uma amostra estratificada de idosos usuários de serviços de atenção primária à saúde de Ribeirão Preto. Os dados foram coletados em cinco unidades distritais básicas de saúde (UBDS) do município por meio de entrevistas pessoais. A análise dos dados foi feita utilizando-se matriz de correlações policóricas e análise fatorial exploratória (AFE) e confirmatória (AFC). Resultados Participaram do estudo 357 idosos com 60 anos ou mais (62,7% do sexo feminino). De acordo com a matriz de correlações policóricas, maiores coeficientes de correlação (> 0,90) foram detectados em 12 pares de itens e agrupados em quatro fatores, conforme sugerido pela AFE. Os resultados da AFC confirmaram a validade de construto da estrutura de quatro fatores do MOS-SSS quando aplicado à amostra do estudo, bem como a estabilidade desse modelo em subamostras distintas. Conclusão A estrutura de quatro fatores do MOS-SSS mostrou-se apropriada para a população estudada e apresentou validade de construto adequada para a avaliação do suporte social em idosos usuários de serviços de atenção primária à saúde.

            Social ties and susceptibility to the common cold.

            To examine the hypothesis that diverse ties to friends, family, work, and community are associated with increased host resistance to infection. After reporting the extent of participation in 12 types of social ties (eg, spouse, parent, friend, workmate, member of social group), subjects were given nasal drops containing 1 of 2 rhinoviruses and monitored for the development of a common cold. Quarantine. A total of 276 healthy volunteers, aged 18 to 55 years, neither seropositive for human immunodeficiency virus nor pregnant. Colds (illness in the presence of a verified infection), mucus production, mucociliary clearance function, and amount of viral replication. In response to both viruses, those with more types of social ties were less susceptible to common colds, produced less mucus, were more effective in ciliary clearance of their nasal passages, and shed less virus. These relationships were unaltered by statistical controls for prechallenge virus-specific antibody, virus type, age, sex, season, body mass index, education, and race. Susceptibility to colds decreased in a dose-response manner with increased diversity of the social network. There was an adjusted relative risk of 4.2 comparing persons with fewest (1 to 3) to those with most (6 or more) types of social ties. Although smoking, poor sleep quality, alcohol abstinence, low dietary intake of vitamin C, elevated catecholamine levels, and being introverted were all associated with greater susceptibility to colds, they could only partially account for the relation between social network diversity and incidence of colds. More diverse social networks were associated with greater resistance to upper respiratory illness.

              Associations of social networks with cancer mortality: a meta-analysis.

              This meta-analysis integrates results of 87 studies on the associations of perceived social support, network size, and marital status with cancer survival. In controlled studies, having high levels of perceived social support, larger social network, and being married were associated with decreases in relative risk for mortality of 25%, 20%, and 12%, respectively. Moderator analyses revealed that never married patients had higher mortality rates than widowed and divorced/separated patients. Associations of social network with mortality were stronger in younger patients, and associations of marital status with mortality were stronger in studies with shorter time intervals, and in early-stage cancer. Relationships varied by cancer site, with stronger associations of social support observed in studies of patients with leukemia and lymphomas and stronger associations of network size observed in studies of breast cancer. Further randomized intervention studies are needed to test causal hypotheses about the role of social support and social network for cancer mortality. Copyright 2009 Elsevier Ireland Ltd.
