Overview
In recent years, adolescents are having higher rates of emotional health problems, such as suicidal thoughts and behaviors (STBs). The goal of this study is to learn about how teens' attention to different types of information relates to their real-world relationships and their emotional health. The investigators hope this study will help understand why some teens go on to have suicidal thoughts and behaviors and other teens do not. This information will help investigators learn how to improve emotional health in teens and reduce teen suicides.
Participants will be 100 female adolescents (ages 12-17) at high risk for STBs who will complete a series of assessments over the course of 6 months. Assessments include a baseline clinical interview, a visit to examine neural responses during a computer tasks, daily smartphone surveys about social experiences and social connectedness, and follow up questionnaires assessing STBs. Participants will also be asked to donate their text messages during the month that they complete smartphone surveys.
The research procedures will help investigators learn how adolescents react to different types of social situations. Investigators want to see if these reactions affect:
- How connected adolescents feel to others in their daily lives
- Adolescents' longer-term risk for suicidal thoughts and behaviors (STBs)
Participants will be asked to:
- Complete a 10-15 minute screening call to determine eligibility for the study
- Complete one 3 hour virtual (or in-person) interview consisting of a clinical assessment and questionnaires.
- Complete a 2.5-hour in person visit to complete computer tasks while record brain signals are recorded
- Complete \~5 minute smartphone surveys three times a day for 30 days, asking about their daily social experiences and their mood and feelings.
- Provide investigators with retrospective access to their text/direct messages from the month the participant was completing the smartphone surveys.
- Complete online follow-up questionnaires at 3 and 6 months
Description
There is no assignment to conditions. All participants will receive the same intervention, which is the completion of an experimental task in which participants are asked to remember the identities of actors displaying happy, sad, angry, and neutral expressions and tested on their memory. The study is designed to evaluate the effect of sustained neurocognitive responsivity to social threat on the participants' social connectedness and suicidality.
This study includes 1) a baseline clinical interview, 2) a laboratory-based EEG assessment (which includes the experimental task described above), 3) smartphone surveys in conjunction with passive ambulatory assessment, and 4) 3- and 6-month follow-up assessments of STBs.
Specifically, after phone screening, female adolescents (n=100, ages 12-17) will complete diagnostic interviews and symptom measures to confirm eligibility. Adolescents' current and lifetime STBs, including the presence, frequency, severity, and age-of-onset of suicidal ideation, plans, behaviors, and attempts will be assessed and differentiated from non-suicidal self-injurious thoughts and behaviors using the Self-Injurious Thoughts and Behaviors Interview.
Eligible participants will be invited for a laboratory visit during which they will complete the ERP Decoding Working Memory task while EEG is recorded. During each trial of the task, a face (angry, sad, happy, neutral) is randomly presented in the center of the screen. Participants are asked to remember the identity of the actor and will be tested on their memory of the identity after a delay. Specifically, participants will be asked to identify the actor from a group of four actors displaying the same emotion.
Following the laboratory visit, adolescents will complete 30-days of smartphone surveys (i.e., ecological momentary assessments \[EMA\]; 3 samples/day) assessing social experiences, social connectedness, and STBs. Following standard procedures, they will be randomly sampled within three blocks of time (morning, after school, evening) for a total of 90 surveys. Youth can "snooze" each prompt for up to one hour. The after-school prompt allows youth to report on experiences and thoughts they had during the school day. Once a week during the 30-day EMA protocol, participants will complete questions assessing STBs currently and during the previous week, using items adapted for EMA from the Columbia-Suicide Severity Rating Scale. During these weekly assessments, participants will indicate any STBs in the last week (i.e., since the last assessment). Finally, participants' time-stamped text, iMessage, and WhatsApp messaging logs will be downloaded at the end of the 30-day period using the software, iMazing, which creates an encrypted backup of these data.
Finally, STB assessments will be repeated at the 3- and 6-month follow-up assessments.
Certain information is withheld to protect the scientific integrity of the study design.
