Methodological issues in developing a scale to measure social support.

In recent years there has been considerable research and clinical interest in developing instruments to assess social supports available to individuals. There is, however, a notable deficiency of attempts to evaluate the psychometric properties of these questionnaires. The present article describes efforts made to evaluate the properties of a Social Relationship Scale (SRS) that was developed as part of a prospective study of the psychosocial influences on the health status of a population. Some descriptive scale statistics are also presented.
