A systematic review of psychological first aid on mental health and well-being

We need to build the evidence: A systematic review of psychological first aid on mental health and well-being, in Journal of Traumatic Stress

key takeaway: "The findings from all studies suggest a positive impact of PFA, with most reporting reduced symptoms of anxiety, depression, posttraumatic stress, and distress, as well as improved ratings of mood, the experience of safety, connectedness, and a sense of control, among youth and adults. Risk of bias was generally high. Inconsistent intervention components, insufficient evaluation methodologies, and a high risk of bias within the reviewed studies present challenges in assessing PFA efficacy, and an imbalance between popular support for PFA and scant evidence of outcome data exists. Further research is needed to justify the proliferation of PFA."
