Introduction: Military members and Veterans are at risk of developing combat-related, treatment-resistant posttraumatic stress disorder (TR-PTSD) and moral injury (MI). Conventional trauma-focused therapies (TFTs) have shown limited success. Novel interventions including Multi-modal Motion-assisted Memory Desensitization and Reconsolidation therapy (3MDR) may prove successful in treating TR-PTSD.

Objective: To qualitatively study the experiences of Canadian military members and Veterans with TR-PTSD who received the 3MDR intervention.

Background: Previous studies indicate that social functioning and resilience can mitigate the adverse psychological effects of interpersonal violence. Unfortunately, the role of these vari-ables has not been studied in survivors of groups, organizations, and communities in which psychological abusive strategies are inflicted to recruit and dominate their members.

Objective: Trauma exposure is common in preschool-aged children. Understanding the psychological impact of such exposure and the prevalence of posttraumatic stress disorder (PTSD) in this population is important for provision of appropriate and timely intervention. This pre-registered (PROSPERO: CRD41019133984) systematic review and meta-analysis examined the prevalence of PTSD in trauma-exposed preschool-aged children.

Introduction Bereaved parents, who have lost a child, have an elevated risk to develop mental health problems, yet, few studies have evaluated the effect of psychosocial interventions developed for bereaved parents. Cognitive–behavioural therapy (CBT), both face to face or digitally delivered, has shown to be an effective intervention for prolonged grief symptoms. Self-help mobile apps offer various advantages and studies show improved mental health after app interventions. No app has yet been evaluated targeting prolonged grief in bereaved parents.
