Enhancing the Effectiveness of Prolonged Exposure Among Suicidal Individuals With PTSD

The long-term goal of this study is to reduce suicidal thoughts and behaviors among treatment-seeking individuals who also have posttraumatic stress disorder (PTSD). Prolonged exposure (PE) and crisis response plan (CRP) have demonstrated empirical support for reducing suicide attempts as compared to treatment as usual. However, no studies to date have assessed their effectiveness when used in combination. In light of this knowledge gap, the primary objective of this study will be to test the effectiveness of PE augmented with CRP as compared to PE with care as usual (self-guided treatment plan), an active comparator, for the reduction of suicide ideations and attempts for individuals with comorbid PTSD.

MicroRNA Correlates of Childhood Maltreatment and Suicidality

This is a research study to find out if childhood trauma and stress are associated with depression or suicidal risk. The study will assess the effects of both short-term and long-term stress on biomarker (e.g. miRNA \[MiRNA\]) levels. miRNAs are a type of RNA (genetic material that is translated into protein) that are found in throughout the body and blood. They are called microRNA because their size is much smaller than typical RNA molecules. miRNAs are highly responsive to environment. This responsiveness is reflected in their expression in individuals who are affected by environment such as stress. The investigators are gathering genetic material, including DNA and RNA, from each participant. The RNA will be taken from the small vesicles and cells in the participant's blood and analyzed. The vesicles are small objects that occur normally in the blood and that contain RNA. This information may help us to understand the cause of mental illness and to improve medical and psychiatric care in the future. There will be 450 participants enrolled in this study.

Social Media Concerns Related to Emotional Experiences in Naturalistic Settings (SCREENS)

The objective of this study is to advance understanding of the relationships between social media use (SMU) and internalizing symptoms among a diverse sample of depressed and/or suicidal youth. Youth (ages 13-18) enrolled in the TX-YDSRN registry study will be recruited for participation in SCREENS. After reviewing the Information Sheet, participants will complete baseline measures assessing internalizing symptoms (e.g., depression, anxiety, suicidal ideation/behavior), and trauma history. They will then complete ecological momentary assessments (EMAs) twice daily for 30 days via the mHealth app, capturing internalizing symptoms, emotional responses to social media, and in-person social support. The mHealth app will also collect the amount of social media use during this 30-day period. From Month 1 through Month 6, participants will receive monthly self-report surveys administered through REDCap. 100 participants This study will enroll youth from the TX-YDSRN registry study who meet all the following criteria: * Be between 13 and 18 years of age at the time of enrollment. * Be currently enrolled in the TX-YDSRN registry study and willing to allow sharing of data from that study. * Own a smartphone and agree to download and use the study mHealth application for the duration of study participation. * Be willing and able to participate in all study requirements and allocate sufficient time to complete study questionnaires and measures.

A Text-Based Expressive Writing Program for Adolescents at Risk of Suicide

The goal of this clinical trial is to learn if a structured expressive writing program can help reduce suicidal thoughts in adolescents and young adults who have experienced suicidal thoughts, suicide attempts, or self-harm. The study will include participants aged 13 to 24 years who are receiving mental health care or have recently been identified as being at risk for suicide. The main questions the study aims to answer are: * Does a structured expressive writing program lower suicidal thoughts compared with usual care alone? * Does the program improve depression, impulsivity, and self-esteem? Researchers will compare participants who receive the expressive writing program together with treatment as usual to participants who receive treatment as usual alone. Participants will: * Be randomly assigned to one of two groups: a writing program group or a usual care group * Complete questionnaires about mood, suicidal thoughts, and well-being at the start of the study, after 4 weeks, and after 8 weeks * If assigned to the writing program group, complete guided writing activities several times per week for 4 weeks. Each writing session will take about 15 to 20 minutes and will focus on understanding emotions, personal experiences, relationships, and meaning in difficult experiences. Researchers will study whether this writing program is a helpful and practical way to support young people who are experiencing suicidal thoughts or emotional distress.

LHC-CIDI-5 in Hong Kong

The World Health Organization Composite International Diagnostic Interview-5th (CIDI-5) is a standardized diagnostic tool used to assess the prevalence of mental and substance use disorders over varying time frames (30 days, 12 months, and lifetime) based on the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) and International Classification of Diseases 10th edition (ICD-10). However, retrospective measurements like the CIDI-5 are susceptible to recall bias, especially for the lifetime experience, which can hinder the reporting accuracy with mental disorders. To mitigate this issue, the life history calendar (LHC) was introduced as an aid to assist respondents in recalling the timing of life events, enhancing the ability of the CIDI-5 to measure the lifetime prevalence of mental disorders. The LHC is a grid structure with columns representing time units and rows representing life domains under study. In a study conducted in Nepal, combining the CIDI-5 with the LHC resulted in a significant increase in the detection of mental disorders compared to using the CIDI-5 alone. This approach did not lead to an increase in false positives after clinical validation. This experiment aims to adapt a Hong Kong version of the LHC based on the Nepalese model and evaluate the effectiveness of the LHC-assisted CIDI-5 (LHC-CIDI-5) compared to the CIDI-5 alone in assessing mental disorders.

Development of a Treatment Prognosis Calculator for the Prevention of Suicide

The goal of this interventional study is to develop and test a treatment prognosis calculator to identify which service members with suicidal ideation or behavior are likely to respond well to the current standard of care treatment and which should instead receive Brief Cognitive Behavioral Therapy (BCBT) as a first-line treatment. The main aims of the study are: * Aim 1: To develop a novel treatment prognostic calculator to predict response to treatment as usual (TAU) and identify treatment-seeking military personnel who are unlikely to respond adequately to TAU for the reduction of suicidal ideation. * Aim 2: To evaluate the performance of the treatment prognosis calculator in a new sample of treatment-seeking military personnel and determine whether BCBT is more effective than TAU for those patients who are predicted not to respond adequately to TAU. Participants will receive mental health treatment as it is typically administered by their mental healthcare treatment team. Members of their mental healthcare treatment team may receive intensive training in BCBT. After their provider has received this training, they may use this treatment as part of standard of care treatment. The timing of this training will be determined randomly. Participants will complete self-report assessments at the beginning of the study (baseline) as well as 3, 6, 9 and 12 months after their participant begins. These assessments will include questions about feelings, thoughts, moods, impulses, substance use, and behavior.

Assessment of Emotion Regulation Strategies Used When Suicidal

Crisis Response Planning is an efficacious, one-session intervention that increases positive affect, decreases negative affect and psychiatric hospitalizations, and reduces suicide attempts by 76% among Servicemembers. Crisis Response Planning is hypothesized to reduce suicidality by identifying a variety of personalized strategies that are designed to strengthen and/or promote emotion regulation processes.Research in nonmilitary samples suggests the effectiveness of emotion regulation strategies varies across situations. The applicability of these findings to suicidality among Servicemembers is unknown. Improved understanding of what strategies work under which circumstances and for whom will significantly advance our ability to prevent suicide among Servicemembers. Hypotheses include: 1. Use of self-management strategies, thinking about reasons for living, and seeking social support at time t will be associated with significant reductions in suicidal ideation at time t+1. 2. Use of distraction, reappraisal, and interpersonal emotion regulation strategies at time t will be associated with significant reductions in suicidal ideation at time t+1. 3. Affect intensity and social context will significantly moderate the time-lagged effects of Crisis Response Planning and emotion regulation strategy use on suicidal ideation. 4. Distinct profiles of demographic (e.g., gender, age), historical (e.g., prior suicide attempts), and psychological characteristics (e.g., emotion dysregulation, symptom severity) will predict who experiences a decrease in suicidal ideation following the use of Crisis Response Planning and emotion regulation strategies. 5. (Exploratory): Individuals who utilize their Crisis Response Planning more frequently and perceive Crisis Response Planning as more effective will be more likely to engage in mental health treatment at follow-up.
