The Validity aand Reliability of the Addiction Outcome Assessment Index (AOAI)

Abstract

Objective: The objective of this study was to develop a short scale that assesses the progress and recovery in addiction treatment with respect to all relevant areas, and to determine its validity and reliability.

Method: After scanning the literature and consulting the experts, a pool of questions was. The pilot form was tested in 10 cases then a final 8-item scale was generated. Clinical sample of the study consisted of 307 alcohol/substance users who applied Turkish Green Crescent Outpatient Counselling Center for psychosocial treatment between March 2016 and March 2017. Non-clinical sample of the study is composed by 102 randomly chosen participants without a history of psychiatric disorder. The reliability of the Addiction Outcome Assessment Index (AOAI) questions was determined by computing the Cronbach's alpha coefficient, and the factor structure analysis was determined by varimax rotation. Analysis of the reliability of the change between sessions was conducted via Reliable Change Index-(RCI).

Results: The Cronbach's alpha coefficient for the total Outcome Assessment Index (AOAI) was 0.80. Therapists' total correlation coefficient was 0.75. Explanatory Factor Analysis revealed 2 factors which explains 43.96% of the total variance. The difference between groups' AOAI-Turkish (BASI) mean score was statistically significant. Cut-off point was determined as 8.63. RCI was 3.5. AOAI's first session mean score was 14.92±5.63, the mean score decreased at the tenth session to 9.4±4.71.

Conclusion: The results showed that AOAI is a valid and reliable questionnaire that can be used to measure the progress of different dimensions of alcohol and substance use.
