[Dialectical behavior therapy : a review of studies on skills training groups and applications in psychiatric settings]

La thérapie cognitivo-comportementale dans les cliniques spécialisées du Pavillon Albert-Prévost dans les 50 dernières années : innovations et évolution

Le Pavillon Albert-Prévost (PAP) a joué un rôle de premier plan dans le développement d’une psychiatrie moderne. Cette institution de soins et d’enseignement en santé mentale a été profondément marquée par la pensée freudienne et a longtemps été considérée comme un lieu phare de l’enseignement de la psychanalyse en milieu hospitalier au Québec. Mais le PAP a aussi su intégrer au fil des ans d’autres approches thérapeutiques, basées sur les données probantes. Si l’arrivée de cliniciens novateurs dans les années 1980, a permis la sensibilisation du milieu à d’autres approches thérapeutiques, la transformation du dispositif de soins en cliniques spécialisées, en 1994, marque un point décisif dans le développement de la thérapie cognitivo-comportementale, mais surtout dans son intégration dans le traitement quotidien de patients souffrant de problématiques diverses et dans son enseignement à des générations de cliniciens.

A comparative study of the effectiveness of group-based cognitive behavioral therapy and dialectical behavioral therapy in reducing depressive symptoms in Iranian women substance abusers

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 (ηp2, 0.75) and DBT (ηp2, 0.86). Therefore, this study highlights the importance of CBT and DBT skills training to substance abusers and provides initial evidence of their effectiveness.
