The Rein-Brief Integrative Biopsychosocial Screening Instrument (R-BIBSI) is a 30-item (alpha = 0.89), non-diagnostic, brief screening tool developed to aid drug and alcohol treatment professionals in treatment planning for persons experiencing substance abuse or dependence. The BIBSI is easily scored by clinical or non-clinical staff to assess six constructs of alcohol use influence: Biological Influence, Psychological Internally Expressed Influence, Psychological Externally Expressed Influence, Social Family Influence, Social Peer/Work Environmental Influence, and Social Cultural Influence. Item reduction processes included think-aloud, predictive validity testing utilizing paired samples t-test, and exploratory factor analysis. A convenience sample of 63 college age students provided data for validation and reliability testing of the R-BIBSI.born digitaldoctoral dissertationsengCopyright and other restrictions may apply.
