Measuring Social Support in People with Mental Illness: A Quantitative Analysis of the Social Network Map.

An instrument is needed for quantitatively evaluating changes in social support in people with mental illness, but no gold standard is available. The Social Network Map is a structured interview for assessing social support that is used in individual care settings, yet provides overwhelming output (16-128 data points per assessment). A method comprising two factors (quality and quantity of the social network) was developed. The psychometric properties were judged to be sufficient. This study shows that data from the Social Network Map can be analysed at the group level, yet further research on the psychometric properties is needed.
