The Addiction Profile Index (BAPI) is composed of 37 items and 5 subscales assessing the characteristics of substance use, dependency diagnosis, the effect of substance use on the person's life, craving, and the motivation to quit using substances. The reliability and validity of the scale were reported in a very recent study. In these current studies, we aimed to develop a clinician-administered form (BAPI-U), clinical form (BAPI-II) and a short form of BAPI (BAPI-K).
Study 1: Psychometric properties of clinician-administered form of BAPI Items of the BAPI were changed to a clinician asked type. In the original BAPI 5-point likert ratings were used. In this questionnaire we used 3-point likert ratings. A total of 150 male inmates were recruited from the Umraniye, Istanbul T-type prison. Cinical Psychologists and guardians of the prison conducted face-to-face interviews with inmates to complete the BAPI. The BAPI-U items were found to be significantly correlated with the self-reported form (0.89). High correlations between interviewer ratings in all subscales were found. Factor analyses yielded four factors for the BAPI-U, which were similar to the BAPI. It was concluded that the BAPI-U has similarities with the BAPI and therefore it may be applied by non-clinical professionals (such as nurses, guardians etc) after a short training period.
Study 2: Development and psychometric properties of the clinical form of the BAPI It is important to know the factors causing alcohol or substance dependence disorders in order to choose the treatment modality and to prevent relapses. In order to assess depression, anxiety, anger, and assertiveness, new items were added to the original BAPI items. This new instrument was named the BAPI-II. The research sample was similar to study 1. The Beck Depression Inventory, Rathus Assertiveness Inventory, Multi-dimensional Anger Scale and STAI-1 were used in this study. The Cronbach Alpha value of the whole scale was found to be 0.79. The self and clinican administered rating correlations were statistically significant. The correlation of the BAPI-II with the other scales was high. One factor was obtained and 54.34% of the variance was explained by this factor. High correlations were found between the ratings of psychologists and prison guardians in all subscales. This shows that the BAPI may be administered by non clinical professionals efficiently.
Study 3: Development and psychometric properties of the short form of the BAPI This study was conducted to develop a shorter version of the BAPI to be used as a screening tool. The study was carried out with 1200 people in 7 different prisons. Based on the results of the statistical analyses, some questions were removed. The short version of the BAPI is composed of 23 questions and is named as BAPI-K. The correlation between the original form and the short version of the form was found to be very high (0.96). Both subscales of the two scales were found to be correlated. The scores of the correlations of the BAPI with CAGE and AUDIT were also found to be statistically significant. The internal consistency of the new scale was found to be satisfactory (0.89). The results have shown that the BAPI-K is a valid and reliable instrument, and can be used as a screening tool.
