Various therapeutic approaches have been used to improve depressive symptoms in substance abusers. In a quasi-experimental study with a pretest-posttest design and experimental and control groups, we examined and compared the effectiveness of two group-based treatment strategies-cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT)-in reducing depressive symptoms among Iranian women substance abusers. The statistical population included all female addict patients who referred to addiction treatment centers of Birjand city in 2015. A sample of 30 subjects were selected through the available sampling method and randomly assigned into experimental (CBT and DBT) and control groups (each group, 10 patients). The data collection instrument was the Beck Depression Inventory (BDI) questionnaire. The patients in the experimental groups were given skills in eight sessions of 90 min. The data were analyzed by the SPSS-19 software by using mean, standard deviation, and percentages at the descriptive level and analysis of covariance (ANCOVA) test at the inferential level. The comparison of the mean depression score before intervention in all the groups showed no significant difference. However, after intervention, the findings showed that both CBT and DBT interventions could reduce the mean scores of depression in women substance abusers, 17.5 ± 3.0 vs 29.3 ± 4.1 (F[1,17] = 51.91, p value < 0.01) and 14.7 ± 1.8 vs 29.3 ± 4.1 (F[1,17] = 106.62, p value < 0.01), respectively, for CBT and DBT. Post-treatment effect sizes were large and did not differ statistically for CBT (η, 0.75) and DBT (η, 0.86). Therefore, this study highlights the importance of CBT and DBT skills training to substance abusers and provides initial evidence of their effectiveness.
人们已经采用了各种治疗方法来改善药物滥用者的抑郁症状。在一项采用前测-后测设计以及实验组和对照组的准实验研究中，我们检验并比较了两种基于小组的治疗策略——认知行为疗法（CBT）和辩证行为疗法（DBT）——在减轻伊朗女性药物滥用者抑郁症状方面的有效性。统计总体包括2015年转诊至比尔詹德市成瘾治疗中心的所有女性成瘾患者。通过便利抽样法选取了30名受试者，并将其随机分为实验组（CBT组和DBT组）和对照组（每组10名患者）。数据收集工具为贝克抑郁量表（BDI）问卷。实验组的患者在八节90分钟的课程中学习相关技能。数据在描述性层面采用SPSS - 19软件进行均值、标准差和百分比分析，在推断性层面采用协方差分析（ANCOVA）检验。所有组干预前的平均抑郁得分比较无显著差异。然而，干预后结果显示，CBT和DBT干预均可降低女性药物滥用者的抑郁平均得分，CBT组为17.5±3.0对比29.3±4.1（F[1,17]=51.91，p值<0.01），DBT组为14.7±1.8对比29.3±4.1（F[1,17]=106.62，p值<0.01）。治疗后的效应量较大，CBT（η，0.75）和DBT（η，0.86）在统计学上无差异。因此，本研究强调了对药物滥用者进行CBT和DBT技能培训的重要性，并提供了其有效性的初步证据。
