ROLE OF PSYCHOSOCIAL FACTORS IN OBTAINING SELF-REPORTS OF ALCOHOL-USEIN A DUI POPULATION

Psychosocial and situational factors were examined as predictors of di screpant reports between driving-under-the-influence (DUI) offenders a nd their collaterals. Psychosocial factors included respondents' expec tancies about telling the truth, normative beliefs, attitudes, confide ntiality, perceived tension, and certainty about their accuracy. Subje cts' reports were assessed in 1 of 3 settings: self-administered at DU I school, group administered at DUI school, or self-administered at ho me. Overall, respondents reported greater alcohol intake than collater als. Respondents also reported greater levels of drinking when they we re more certain of their accuracy and when they were concerned that co nfidentiality might be violated. Discrepancies between respondent-coll ateral reporting were primarily attributable to psychosocial factors a nd not to situational factors. Decreased collateral familiarity with t he respondent's drinking was also related to greater discrepancies.
