Skills to Enhance Positive Affect in Suicidal Adolescents

Study Overview
=================
Brief Summary
-----------------
The prevalence of suicidal behaviors in adolescents remains unacceptably high and is a significant public health concern. The investigators propose a new treatment approach in which skills to increase positive emotions are taught to the most vulnerable at-risk adolescents, those admitted to an inpatient psychiatric unit due to suicide risk. The investigators believe that teaching skills to increase positive emotions will lead to better problem-solving, increased social support, and other benefits which will serve as protective factors and decrease suicide risk.

Detailed Description
-----------------
The prevalence of suicidal behaviors in adolescents remains unacceptably high. Reviews of published randomized controlled trials (RCTs) for adolescent suicidality conclude that treatments to date have been minimally efficacious. The preponderance of interventions focus on crisis intervention, underlying psychiatric disorders, regulating negative affect and reducing cognitive distortions. However, our pilot work and other recent data suggest the importance of considering how low positive affectivity contributes to suicide risk independent of other risk factors and may be another mechanism that leads to suicidal behaviors. Our model is based on Fredrickson's empirically-supported Broaden and Build model which asserts that the function of positive affect (PA) includes helping individuals thrive by improving social supports, problem-solving, and personal resilience. Each of these areas is instrumental in decreasing suicidal behavior. We propose that PA increases survival directly by decreasing suicidal ideation and indirectly by increasing social support and problem-solving. In this R34 treatment development grant we seek to develop a novel, individual skills-based, PA intervention, delivered adjunctively to treatment as usual (TAU), targeting the highest risk adolescents - those hospitalized due to suicide risk. We focus on three strategies that have been demonstrated to increase sustainable (vs. transient) PA in community and depressed adults: meditation, gratitude, and savoring. There are several ways to practice each strategy; we take into account patient preferences in a personalized approach in which patients select the practice(s) that fits best with their needs and circumstances. We propose using multiple means of intervention delivery that includes text messaging, to reinforce in-vivo practice. Our intervention, Skills To Enhance Positivity Program (STEP) includes two phases: a) in-person phase consisting of 3 individual in-person sessions and 1 joint parent session during the inpatient hospital stay to teach positive affect skills and develop a personalized intervention; b) remote delivery phase which consists of weekly telephone booster calls and daily text messages over 4 weeks post-discharge. The phone calls will be used to review or adjust personalized intervention components and reinforce use of skills. The text messages will include self-scripted reminders to practice skills and links to online resources. STEP will be tested in an open trial with 20 participants, and after further revision, in a pilot RCT, compared to TAU in a sample of 50 adolescents. The primary goal of this intervention is for patients to increase positive affect by incorporating skills and practices into their normal home-based routines, which we believe will lead to increases in problem-solving and social support and decreases in suicidal ideation. This is a novel intervention for a high-risk acute population via a different mechanism (i.e. PA), and conceptually distinct from other empirically examined theoretical approaches.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dot Probe Task | Dot probe tasks are administered to assess for attentional biases. The task is a computer task in which participants are presented with stimuli (e.g., words) of different valences (positive/negative/neutral) at the same time (e.g., smiling face and a neutral face), followed by a probe (*) on one side. Participants are asked to hit a key that corresponds to the correct side in which the probe appeared. The reaction time of their response is indicative of their attention to the valenced image/word. Trials are counterbalanced so that valences appear equally on each side. Faster reaction time (less milliseconds) to positive images/words indicates an attentional bias for positive stimuli. The scores reported here represent bias scores. Positive scores indicate a bias to positive stimuli, negative scores indicate a bias towards neutral stimuli. | Baseline, 1 month Post Treatment, 4 month Follow-Up | 
| Modified Differential Emotions Scale (Positive Emotions Sub-scale) | The Modified Differential Emotions Scale is a self-report measure comprised of ratings for positive and negative affect. For example, participants are asked to rate the extent to which they feel Content, serene, peaceful right now on a likert scale ranging from 1 (not at all) to 5 (extremely). The scores reported are averages for the positive emotions, and thus can be interpreted as ranging from 1 (not at all) to 5 (extremely). We expected an increase in positive affect ratings following the intervention. | Base, 1 month Post-Treatment, 4 month Follow-Up | 
| Suicide Events | Number of participants who have attempted suicide or have had emergency intervention to intercede a suicide attempt. | 1 month, 6 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Suicide Ideation Questionnaire (SIQ) | The Suicidal Ideation Questionnaire is a 30 item self-report measure that was administered to the adolescent to ascertain the frequency of thoughts of death and suicide. Respondents are asked how often they have had these thoughts (e.g., I thought about killing myself) in the past month ranging from almost every day = 1 to I never had this thought =7. Scores are then reversed and transformed such that higher scores indicate higher suicidal ideation, with a range of 180 (highest suicidal ideation) to 0 (no suicidal ideation). | Baseline, 1 month Post-Treatment, 4 month Follow-Up | 
| Beck Depression Inventory | The Beck Depression Inventory is a 21 item self-report form of depression but can be and has been administered to the parent to respond about their child. This questionnaire consists of 21 groups of statements. For example, for Sadness, respondents are asked to select between 0 (My child does not feel sad.), 1 (My child feels sad much of the time), 2 (My child is sad all the time), and 3 (My child is so sad or unhappy that he/she can't stand it.). Higher scores indicate higher depression with a maximum score of 63 and a minimum score of 0. | Baseline, 1 month Post-Treatment, 4 month Follow-Up | 
| Columbia Impairment Scale Parent Version | The Columbia Impairment Scale (parent version) is a 13-item scale in which parents are asked to respond about their child's impairment in a variety of domains on a scale of 0 (no problem at all) to 4 (very bad problem). Scores are summed such that higher scored indicate higher functional impairment, with a maximum score of 52 and a minimum score of 0. | Base, 1 month Post-Treatment, 4 month Follow-Up |
