Climate change is negatively impacting mental health through multiple pathways. Research to date has largely focused on characterising the link between climate change and mental health and no mental health and psychosocial support intervention has been explicitly designed to address the mental health consequences of climate change. In this commentary, we argue that brief, scalable psychological interventions represent an opportunity to fill this gap.

Background
Trauma-focused psychotherapies for combat-related posttraumatic stress disorder (PTSD) in military veterans are efficacious, but there are many barriers to receiving treatment. The objective of this study was to determine if cognitive processing therapy (CPT) for PTSD among active duty military personnel and veterans would result in increased acceptability, fewer dropouts, and better outcomes when delivered In-Home or by Telehealth as compared to In-Office treatment.

Due to its novelty and lack of empirical study it remains unclear if a service dog truly mitigates the burden of post-traumatic stress disorder (PTSD) symptoms. To cross sectionally investigate the effect of service dogs on veterans and first aid responders with PTSD, we studied subjective and physiological parameters in 65 individuals divided over four groups. These groups were: veterans and first aid responders with PTSD and a service dog (n = 20), with PTSD and a companion dog (n = 10), with PTSD without a dog (n = 12) and a group without PTSD (n = 23).

Background: As provisions of mental healthcare services to military and veteran populations increases the risk to service providers developing secondary traumatic stress (STS), efforts areneeded to examine the impact of delivering novel interventions which may include 3MDR. As avirtual-reality supported intervention, 3MDR exposes the patient, therapist and operator tographic and sensory stimuli (i.e. narratives, imagery, smells, and music) in the course of the intervention.
