Remission, Recovery, Relapse, and Recurrence Rates for Suicide Attempts and Non-Suicidal Self-Injury for Suicidal Youth Treated With Dialectical Behavior Therapy or Supportive Therapy
Journal of the American Academy of Child and Adolescent Psychiatry(2024)
摘要
Objective
To evaluate rates of remission, recovery, relapse, and recurrence in suicidal youth who participated in a clinical trial comparing Dialectical Behavior Therapy (DBT) and Individual and Group Supportive Therapy (IGST).
Method
Participants were 173 youth, aged 12 to 18 years, with repetitive self-harm (including at least 1 prior suicide attempt [SA]) and elevated suicidal ideation (SI). Participants received 6 months of DBT or IGST and were followed for 6 months post-treatment. The sample was 95% female, 56.4% White, and 27.49% Latina. Remission was defined as absence of SA or non-suicidal self-injury (NSSI) across one 3-month interval; recovery was defined across 2 or more consecutive intervals. Relapse and recurrence were defined as SA or NSSI following remission or recovery. Cross-tabulation with χ2 was used for between-group contrasts.
Results
Over 70% of the sample reported remission of SA at each treatment and follow-up interval. There were significantly higher rates of remission and recovery and lower rates of relapse and recurrence for SA in DBT than for IGST. Across treatments and time points, SA had higher remission and recovery rates and lower relapse and recurrence rates than NSSI. There were no significant differences in NSSI remission between conditions; however, participants receiving DBT had significantly higher NSSI recovery rates than those receiving IGST for the 3- to 9-month, 3- to 12-month, and 6- to 12-month intervals.
Conclusion
Results showed higher percentages of SA remission and recovery for DBT as compared to IGST. NSSI was less likely to remit than SA.
Diversity & Inclusion Statement
We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants.
