Abstract

Fluctuations in motivation to change in persons with substance use disorder (SUD) may lead to their dropping out of treatment. ADHD in SUD persons is known to have a negative effect on motivational processes in general. Residents with comorbid ADHD may therefore experience more fluctuations in motivation during treatment. We assessed the development of motivation to change within the initial three months of treatment in a sample of 80 residents treated in certified therapeutic communities in the Czech Republic. ADHD was assessed by means of a DIVA 2.0 diagnostic interview and motivation to change by the Change Questionnaire. We found that motivation decreased between the first and the second wave: t(79)=2.09, p=.040, Cohen’s d = 0.23. The persons with ADHD did not differ from the rest in terms of their first-wave motivation (Bayes factor 10 = 0.235). The interaction between ADHD and between-waves differences in motivation was not confirmed (F(1;78)=2.65, p=.108); however, a Tukey post hoc test showed a significant between-waves decrease in motivation in the ADHD group, while in the clients without ADHD between-waves differences in motivation were not found. We found a small decrease in motivation to change after three months. Our data suggested that ADHD may affect the development of motivation.

摘要

物质使用障碍 (SUD) 患者改变动机的波动可能导致他们退出治疗。众所周知，SUD 人的 ADHD 通常会对动机过程产生负面影响。因此，患有 ADHD 共病的居民在治疗期间可能会经历更多的动力波动。我们评估了在捷克共和国经过认证的治疗社区接受治疗的 80 名居民的样本中，在治疗的最初三个月内改变的动机的发展。ADHD 通过 DIVA 2.0 诊断访谈和改变问卷的改变动机进行评估。我们发现动机在第一波和第二波之间下降：t (79)=2.09, p =.040, Cohen's d = 0.23。患有多动症的人在第一波动机方面与其他人没有区别（贝叶斯因子 10 = 0.235）。未证实 ADHD 与波间动机差异之间的相互作用（F (1;78)=2.65, p =.108）；然而，Tukey 事后测试显示 ADHD 组的波间动机显着下降，而在没有 ADHD 的客户中，未发现波间动机的差异。我们发现三个月后改变的动力略有下降。我们的数据表明，多动症可能会影响动机的发展。
