Study Details

Study Description

Brief Summary

To inform the development of a technology-augmented adaptive intervention for adolescents at risk for suicide, the goal of this study is to conduct a Sequential, Multiple Assignment, Randomized Trial (SMART) pilot of a Motivational Interview (MI)-enhanced safety planning intervention (MI-SafeCope). Findings from this study will provide the groundwork for the construction of a technology-augmented adaptive intervention that could lead to a reduction in suicidal behaviors and related events during the high-risk post-discharge period-an important suicide prevention target.

Intervention Model Description:
This Sequential, Multiple Assignment, Randomized Trial (SMART) pilot of a Motivational Interview (MI)-enhanced safety planning intervention is designed to inform the development of a technology-augmented adaptive intervention for youth at risk for suicide. The MI-SafeCope intervention includes three components: (1) MI-enhanced safety plan delivered during hospitalization (encompassing individual and family meetings); (2) post-discharge booster call; and (3) post-discharge daily text message boosters. In this SMART pilot, adolescents will be randomized to either MI-enhanced safety plan alone or in combination with text boosters for two weeks after discharge (Phase 1 intervention). At the end of week 2, adolescents will be re-randomized to two additional weeks of either: continuation of Phase 1 intervention or continuation of Phase 1 intervention with the addition of post-discharge booster call. Thus, participants will receive one of four treatment sequences (Groups A-D).This Sequential, Multiple Assignment, Randomized Trial (SMART) pilot of a Motivational Interview (MI)-enhanced safety planning intervention is designed to inform the development of a technology-augmented adaptive intervention for youth at risk for suicide.

Arms and Interventions

Arm Intervention/Treatment
Other: Safety plan + booster text messages + booster call (Group A)

Sequencing of MI-SafeCope intervention components (Phase 1 and Phase 2) resulting in Group A: Participants will receive the in-person MI-enhanced safety plan (individual meeting with the adolescent and a family meeting) during hospitalization -- focused on developing a personalized list of coping strategies and enhancing adolescents' motivation and self-efficacy to utilize these strategies-- which will be followed by 4 weeks of daily post-discharge booster text messages and a phone booster call.

Behavioral: MI-Enhanced Safety Plan at Hospitalization (1st Component)
The MI-enhanced safety plan intervention component is delivered during hospitalization and includes an individual and family meetings. The goal of the individual meeting with the adolescent is to develop an individualized safety plan for use during a suicidal crisis. This "best practices" approach of safety planning is augmented with Motivational Interviewing (MI) as a core strategy to explicitly elicit adolescents' motivation and commitment to behavior change (i.e. use safety plan; adaptive coping), address barriers or ambivalence, and strengthen self-efficacy. The focus of the family meeting, which is similarly guided by MI, is to prepare parents/guardians, with input from the adolescent, for how they may support the adolescent in implementing the individualized safety plan after discharge and on strengthening parents' commitment and self-efficacy.

Behavioral: MI-Enhanced Text Boosters (2nd Component)
For participants randomized to receive text boosters, booster text messages will be sent daily for 4 weeks. The messages will be tailored to encourage use of individualized coping strategies identified as part of safety planning at hospitalization and will include additional adaptive coping tools and resources. The text message content and tone will be consistent with principles of MI.

Behavioral: MI-Enhanced Booster Call (3rd Component)
The focus of the post-discharge booster phone call with adolescent and with parent, each conducted separately, will be to to further adjust the safety plan to better meet post-discharge needs, to further enhance adolescents' motivation and commitment to use coping strategies, and to further support adolescents' and parents' self-efficacy to manage suicidal crises.

Other: Safety plan + booster text messages (Group B)

Sequencing of MI-SafeCope intervention components (Phase 1 and Phase 2) resulting in Group B: Participants will receive the in-person MI-enhanced safety plan during hospitalization followed by 4 weeks of daily booster text messages post discharge.

Adverse Events

Time Frame Data on suicide attempts was collected over a 3 month period.
Adverse Event Reporting Description Since all participants were hospitalized for suicide risk (ideation or attempts) to be eligible, those who were unreachable at follow-up weren't included in denominators of suicide attempt data, as they couldn't be presumed to have attempted suicide nor could they be presumed with certainty not to have attempted suicide. Thus it is most accurate to report only known data that is based on collected AEs. Non-serious Adverse Events were not collected.
