The Significant-other Behavior Questionnaire (SBQ): an instrument for measuring the behavior of significant others towards a person's drinking and abstinence.

The psychometric properties of the Significant-other Behavior Questionnaire (SBQ), an instrument measuring the specific social support in terms of the patient's drinking. Assessments of the significant other's behavior in the presence of the patient drinking is provided by both the patient and significant other. Data from the two SBQ forms were analyzed with a principal axis factor analytic procedure with varimax rotation. The scales were similar for the two forms with four behavioral reactions, withdraw from the patient, support drinking, support sobriety, and punish drinking. Correlations between the two forms on the same four scales were higher than correlations within groups on three of four scales and differed from measures of general social support. Applications of the SBQ are discussed.
