Brief summary
Suicide cognitions are conceptualized as enduring, chronic vulnerability factors that predispose individuals to suicidal crises. Therefore, modification of these beliefs may reduce suicidal thoughts and behaviors. The goal of this research is to develop, refine, and pilot-test a mobile intervention to reduce cognitions that contribute to elevated suicide risk and to assess the impact of reductions in suicide cognitions and anger cognitions on suicide risk and functioning.
Detailed description
Suicide cognitions are conceptualized as enduring, chronic vulnerability factors that predispose individuals to suicidal crises. Therefore, modification of these beliefs may reduce suicidal thoughts and behaviors. In addition to suicide cognitions, another potentially modifiable risk factor for suicide is anger. The goal of this research is to develop, refine, and pilot-test a mobile interpretation bias modification intervention to reduce cognitions that contribute to elevated suicide risk and to assess the impact of reductions in suicide cognitions and hostile interpretation bias (a cognitive bias that is associated with anger) on suicide risk and functioning.
Interventions
This is an interpretation bias modification intervention that is designed to target hostile interpretation bias. Participants will be instructed to complete at least 5 treatment sessions per week for a period of 4 weeks. Each session takes approximately 10 minutes.

Intervention model description
Participants will use the Mobile Intervention for Suicidal Thoughts (MIST) intervention for 4 weeks, followed by the Mobile Intervention for Reducing Anger (MIRA) for another 4 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Recruited | Through study completion (approximately 10 months) | Participant feasibility expectation will be met if recruitment is 75% (i.e., N = 8) or greater of recruitment expectation (N = 10). |
| Number of Enrolled Participants Who Complete the MIST Intervention | Post-MIST assessment visit (approximately one month after enrollment) | Treatment retention feasibility goal will be met if attrition from the MIST intervention is no more than 25% (i.e., not more than 3). |
| Number of Participants Reporting Satisfaction With MIST App: Client Satisfaction Questionnaire | Post-MIST assessment visit (approximately one month after enrollment) | Patient satisfaction will be assessed with item #7 from the Client Satisfaction Questionnaire. This item is scored on a scale of 1 to 4, with one indicating lower satisfaction and 4 indicating greater satisfaction. The patient satisfaction goal will be met if 80% or greater of participants indicate score a 3 or 4 on this item (i.e., at least 8 participants score a 3 or 4). |
| MIST App Utilization | Post-MIST assessment visit (approximately one month after enrollment) | MIST app utilization goal will be met if MIST app utilization rates are greater than 50% of expected use (i.e., mean # of sessions completed is greater than 10). |

| MIST Intervention Followed by MIRA Intervention These are both mobile interventions that use interpretation bias modification (IBM) techniques to reduce cognitive biases. The MIST app targets suicidal cognitions and the MIRA app targets hostile interpretation bias (which contributes to anger). The MIRA application has already been developed, but the MIST application is newly developed based on the same procedures. All participants will complete the MIST intervention and provide feedback so that we can refine it. We will also be collecting EMA data on to examine how changes to suicide cognitions and hostile interpretation bias (by use of the two apps) affects suicidal ideation and functioning.
Mobile Intervention for Suicidal Thoughts (MIST): This is an interpretation bias modification intervention that is designed to target cognitive factors that contribute to suicide risk. Participants will be instructed to complete at least 5 treatment sessions per week for a period of 4 weeks. Each session takes approximately 10 minutes.
