Dynamic Deconstructive Psychotherapy Versus Brief Intervention and Contact for Suicidal Adolescents and Young Adults

Overview

The purpose of this clinical trial is to assess whether 6 months of treatment with Dynamic Deconstructive Psychotherapy (DDP) is more effective for reducing thoughts of suicide in suicidal adolescents and young adults than usual care in the community supplemented with Brief Intervention and Contact (BIC). DDP and BIC are two evidence-based practices shown to be more effective than usual care at reducing suicidality. Participants will be randomly assigned to receive DDP treatment with safety planning and optional medication management or BIC treatment with safety planning and optional medication management. Participants in both groups will receive the assigned treatment at SUNY Upstate Medical University's Psychiatry High Risk Program (PHRP). Each participant is anticipated to take part in this trial for up to one year.

Currently, it is uncertain which treatments work best to reduce the frequency and intensity of suicidal thoughts in adolescents and young adults. Usual care typically involves a combination of counseling and psychiatric medications targeting the underlying psychiatric conditions. However, usual care is sometimes ineffective at reducing thoughts of suicide. In previous studies, Dynamic Deconstructive Psychotherapy (DDP) and Brief Intervention and Contact (BIC) have been shown to be more effective than usual care at reducing suicidality. The investigators anticipate that participants in the DDP treatment group will achieve greater reductions in suicidal thoughts after 6 months of treatment than participants in the BIC treatment group, as assessed by a combined measure of suicide ideation (CSI). DDP is a manual-based psychodynamic therapy developed at Upstate by the principal investigator for severely ill individuals with borderline personality disorder, but has since been applied to other disorders. DDP combines elements of translational neuroscience, object relations theory, and deconstruction philosophy and involves weekly one-hour individual sessions for up to 12 months. DDP differs fundamentally from most other therapies in that it is a recovery-based model, instead of a chronic illness-based model of care. Instead of providing advice, problem-solving, or skills to cope with the symptoms and dysfunction of chronic illnesses, DDP attempts to address the underlying vulnerabilities of these illnesses in order to provide transformative healing leading to recovery. During weekly sessions, clients recount recent emotion-laden experiences, explore their emotions and reactions, reflect upon their experiences in increasingly integrative, complex, and realistic ways, learn how to develop close, authentic relationships, and work towards self-acceptance and self-compassion. Two randomized controlled trials of DDP have been conducted and published, one in Syracuse and the other in Iran by independent groups of investigators. These trials showed strong and significant treatment effects across a broad range of outcomes, including borderline personality disorder symptoms, social and occupational functioning, depression, substance use, dissociation, and suicidal behaviors. A naturalistic cohort study comparing DDP to dialectical behavior therapy indicated statistically significant superiority of DDP for depression, borderline personality disorder, functioning, and self-injury. After an independent investigation of the evidence-base of DDP research, the federal agency SAMHSA included DDP in its National Registry of Evidence-Based Programs and Practices and later in its national Suicide Prevention Resource Center as a treatment with evidence of effectiveness for depression, alcohol abuse, borderline personality disorder, and suicidal behaviors. BIC is a well-established protocol-based intervention developed by the World Health Organization for providing brief supportive contacts and coordination of care. There have been numerous studies documenting reductions in suicide ideation and/or attempts when safety planning is combined with brief supportive contacts by phone, postcards, or brief follow-up visits after suicide-related events. Brief supportive contacts in combination with safety planning and facilitation of transitions in care from inpatient to outpatient settings have become a best practice in suicide prevention, and are essential components of the Zero Suicide Model of care. In randomized controlled trials, BIC has shown efficacy in preventing suicide and reducing suicide attempts, as well as in reducing suicide ideation when combined with safety planning. This study will enroll 106 participants, with 53 participants in each group. Participants will be randomly assigned to receive either DDP plus safety planning and psychiatric management or BIC plus safety planning and psychiatric management. Participants in the DDP treatment group will meet with an assigned therapist for 50 to 60 minutes on a weekly basis for 12 months. Participants in the BIC treatment group will meet with an assigned therapist for a 60-minute initial session and then eight 30-minute follow-up visits scheduled at 1, 2, 4 weeks and 2, 3, 4, 6, and 12 months after study entry. Outcome measures are administered by a research coordinator at baseline and 3, 6, 9, and 12 months after study entry. Randomization will involve a minimization method of group assignment to ensure comparability of the two treatment groups on the following three variables: 1) treatment arm; 2) adolescent vs. adult and 3) initial C-SSRS suicide ideation score of 2 or 3 vs. score of 4 or 5. This approach of matched group metrics involves assigning scores to each group based upon the distribution of the selected variables within each group and on each group's total number of participants. Participants are assigned to a given group so as to minimize the differences in total scores between the two groups. In the instances where differences in scores between the groups are equivalent, the participant is assigned randomly by a random number generator. The investigators will compare the two groups of study participants (DDP and BIC) in intent-to-treat analyses. The primary outcome will be the change in Combined Suicide Ideation (CSI) over the first 6-month time interval. The change in CSI scores over the first 6 months will be analyzed by two-factor mixed model analysis of variance (ANOVA), with time as the repeated measure within-subject factor and group (DDP and BIC) as a between-subject factor. Missing data points will be estimated through multiple imputation.
