Different social network and social support characteristics, nervous problems and insomnia: Theoretical and methodological aspects on some results from the population study ‘men born in 1914’, Malmö, Sweden

Abstract

A representative sample of 68-year-old men in the Swedish city of Malmö, were interviewed in detail regarding their social network, social support and social influence as a part of an extensive examination of their health status. Emphasis in this paper is put on the definition and operationalization of different social network, social support and social influence characteristics included in a tentative model. The reliability and validity of the different social network, social support and social influence indices are analyzed and discussed. The relation between the different indices and marital status and social class are analyzed implying that men living alone and men in the lowest social class have the most insufficient social network, social support and social influence. The indices were then used in an analysis of nervous problems and insomnia. Social anchorage, social participation and contact frequency, all subconcepts of social network, had independent associations with mental health in this cross-sectional study. The addition of the social network, social support and social influence indices to social class and marital status gives a more differentiated and thereby a more valid picture of the association between the psychosocial environment and this type of mental health problems.
