Pragmatic Patient-oriented Extension Study of Dialectical Behavior Therapy Booster Sessions for Youth With and/or at Familial Risk for Bipolar Disorder

The study intervention is DBT adapted for youth with and/or at familial risk for bipolar disorder. Participants will have completed one full year of DBT in a previous study. This study is examining use of booster sessions. It is delivered in the form of individual sessions and skills sessions, based on the preference of the study participant. The study participant may also receive skills coaching via phone. There is no standard reference therapy/comparator against which the study intervention is being compared.

About this study

The study intervention is DBT adapted for youth with and/or at familial risk for bipolar disorder. Participants will have completed one full year of DBT in a previous study. This study is examining use of booster sessions. It is delivered in the form of individual sessions and skills sessions, based on the preference of the study participant. The study participant may also receive skills coaching via phone. DBT consists of four components: individual therapy sessions, skills sessions, skills coaching via phone, and consultation team. Given this study is an extension of an existing study of full DBT, the proposed intervention is not prescriptive; that is, we have opted not to dictate how many sessions participants will receive and/or when. Instead, we have opted to leave this decision for participants and their treatment providers to reach collaboratively. Participants, in consultation with their study therapist, will select the frequency of their booster sessions. This may include individual and/or skills sessions in addition to phone coaching for those who attend individual sessions at least once per month. DBT consultation will also remain a component of the treatment. This level of intervention seems appropriate, given that participants have completed a full year of DBT and thus may require a less intensive treatment for continued care. Moreover, it is important to give youth autonomy in treatment options to model health decision making for other life choices.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

The participant must meet all of the inclusion criteria to eligible for this clinical trial:

Treatment and study plan

Dialectical behavioral therapy

Behavioral

DBT will be conducted over 2 years. Participants and their treatment providers will decide on the frequency of sessions collaboratively. This may include individual and/or skills sessions in addition to phone coaching for those who attend individual sessions at least once per month. DBT consultation will also remain a component of the treatment. Participants may choose skills training, conducted in approximately 60 minute meetings, and individual therapy conducted in approximately 60 minute sessions. Family participation in skills training is highly encouraged. Skills training may include: psychoeducation, mindfulness skills, emotion regulation skills, distress tolerance skills, interpersonal skills, and walking the middle path skills. Individual therapy sessions aim to aid the youth in applying skills in their daily lives. We adopt the standard DBT hierarchy of treatment targets.

Other names: DBT

Primary outcomes

  1. Total number of DBT sessions used during the study interval measured using the Therapy Tracking Form

    Time frame: At the end of study completion (five years)

    The Therapy Tracking Form will be used to document the date of the therapy session, type of session, session duration, content, and scheduled date for next therapy visit. This form will be completed by the study therapist after each therapy session.

  2. Number of unscheduled/expedited DBT sessions that are required measured using the Therapy

    Time frame: At the end of study completion (five years)

    The Therapy Tracking Form will be used to document if the session was a scheduled session or an unscheduled/expedited session. This form will be completed by the study therapist after each therapy session.

  3. Frequencies of different factors/circumstances leading to the need for unscheduled/expedited DBT sessions measured using the Therapy

    Time frame: At the end of study completion (five years)

    The Therapy Tracking Form will be used to document the reason for the unscheduled/expedited DBT session. This form will be completed by the study therapist after each therapy session.

Secondary outcomes
