Exploring the Impact of the Caring Contacts Intervention on the Stress and Distress of Veterans and Service Members: Protocol for a Randomized Controlled Trial
Notice bibliographique
Résumé
BACKGROUND: Suicide is a recognized global public health problem that continues to pose substantial challenges in the United States. Veterans and service members are particularly at risk. Caring Contacts is a simple, scalable intervention comprising brief, periodic messages sent over 1 to 2 years that express unconditional care and concern. It reduces suicide risk among individuals with recent suicidal ideation or attempts and has demonstrated acceptability in military and veteran samples, but little is known about the mechanisms of Caring Contacts or its applicability to populations who are not suicidal. OBJECTIVE: We aim to evaluate if receiving Caring Contacts reduces suicide risk among veterans and active service members recruited based on their stress or distress levels, using ecological momentary assessment (EMA) and survey measures of suicidal ideation and cognitions; to examine the experiences of diverse veterans and service members with Caring Contacts; to evaluate if receiving Caring Contacts reduces distress (depression, substance use consequences, hopelessness, defeat, and psychological pain); and to identify the potential mechanisms of action for Caring Contacts (mattering, connectedness, social responsibility, and entrapment). Using EMA, this study will be the first to investigate mechanisms of the Caring Contacts intervention both in real time, as the messages are received, and over the course of 1 year. METHODS: In this randomized controlled trial, veterans or service members (N=510) experiencing stress or distress recruited via social media advertisements will be offered best available resources and randomized into 1 of 3 study conditions: 12 months of Caring Contacts and monthly EMA, 12 months of Caring Contacts without monthly EMA, or 12 months of monthly EMA alone. The individuals in the Caring Contacts conditions will receive 13 messages. A subset of participants from each condition will be asked to complete a qualitative interview after the 12-month follow-up about their study experience. RESULTS: This trial was funded in October 2023; recruitment started in April 2024 and will conclude in May 2025. As of December 2024, we have enrolled 321 participants. Final quantitative data collection will be completed by July 2026, 2 months after the final 12-month follow-up date. Data from the qualitative interviews will be collected until September 2026. Data analysis will occur following data collection, and the results are expected to be published in winter 2027. CONCLUSIONS: This study will be the first randomized controlled trial evaluating the impact of Caring Contacts among service members and veterans who were not recruited based on suicidality. If effective, our findings will demonstrate that Caring Contacts is beneficial for reducing multiple forms of psychological distress and suicide risk. In addition, we will evaluate potential mechanisms explaining the effects of Caring Contacts and assess the utility of EMA as a primary measure of outcome in suicide research trials.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
