Abstract
Process analysis of weekly self- and external assessments of adolescents with substance abuse disorder during long-term psychotherapy Abstract.
OBJECTIVE
Little is known about the course of emotional and motivational states in young patients with substance use disorder (SUD) during long-term treatment.
METHOD
We collected weekly self-reports from N = 42 adolescents, resulting in 853 questionnaires. Additionally, 708 observations were obtained from their key carers. Principal component analysis (PCA) was used to explore the dimensional structure of the questionnaires. Multi-level models were applied to test for group differences and time series models to evaluate dependencies on the person level.
RESULTS
PCA yielded four factors: negative mental state, appreciation of the setting, motivation, and addiction dynamics. Correlations between self- and (unidimensional) carer-reports were low to moderate, but differential on the individual level. Scores of all four scales decreased during the course of treatment. The level of appreciation during the initial phase was the only significant predictor for drop-outs of treatment later on: in drop-outs, appreciation decreased, whereas it increased in completers.
CONCLUSION
Appreciation was the most important predictive factor for a regular therapy ending in SUD, whereas motivation showed fluctuations typical for adolescence. Addiction dynamics were of lesser relevance than commonly expected. Therefore, programs in long-term SUD treatment should focus more on improving appreciation than on issues of addiction itself.
