Dialectical Behavior Therapy Group Skills Training for Adults with Attention-deficit/hyperactivity Disorder
Objective:The study aimed to explore the feasibility,acceptability,and preliminary efficacy of dialectical behavior therapy(DBT)in the Chinese population using a single-arm design,and to explore the potential predictors of the treatment outcome.Methods:Twenty adults with ADHD were allocated to the DBT group skills training and reported their feasibility and acceptability.Multiple liner models were used to estimate the preliminary efficacy of DBT since the ADHD core symptoms,emotional symptoms,emotional regulation strategies,executive functions(EF),and self-esteem were evalu-ated before treatment,mid-treatment,at the end of the 12-week DBT,and the 3-month follow-up.Multiple linear regres-sions were used to identify baseline predictors of the treatment outcome at the end of the 12-week DBT,and the 3-month follow-up.Results:Patients presented a high attendance rate(88.3%),and sufficient participant satisfaction(4.3~4.8/5 scores).ADHD patients exhibited significant decreases in core symptoms(g=0.634~1.031)and depressive symptoms(g=0.379~0.664).Significant increases in emotional regulation strategies(g=0.296~0.616),self-awareness(g=-0.386~-0.581),and self-esteem(g=-0.305~-0.298)were also found,which could be maintained to T5.Gender(male),early onset of treat-ment,and higher scores of ADHD core symptoms at baseline predicted better treatment outcomes.Higher EF scores,the ex-istence of psychiatric comorbidities and personality disorders and comorbidity at baseline predicted poorer treatment out-comes.Conclusion:The feasibility,acceptability,and preliminary efficacy of the Chinese version of DBT were demonstrat-ed,suggesting that DBT would help patients to get reductions in multiple dimensions.The analysis of predictive factors of treatment outcomes provided a preliminary theoretical basis for the optimization of indications.
