Self-reports of Substance Abusers: The Relation between Social Desirability and Social Network Variables.

It is important to examine social desirability when interpreting self-report data from substance abusers. Social desirability is the tendency to respond on surveys that make people appear more favorable to others; thus, a strong desire for social approval is related to minimized reports of substance use. In the present study, the relationship between social desirability and different types of social support was examined within 582 residents of communal-living recovery homes (i.e., Oxford Houses). Although effect sizes were small, results may suggest that participants reported social network variables in a socially desirable manner; this tendency towards self-deception even predicted misrepresentations of these constructs eight months later. In addition, self-reports of the substance use habits of friends and family were more prone to social desirability than the reporting of other social network characteristics. Overall, it is suggested that social desirability might be taken into account when examining substance abusers' self-reports of social support variables.
