Question 152

A team of clinical psychologists investigated whether a new Cognitive Reframing Protocol was more effective than standard Mindfulness-Based Stress Reduction (MBSR) in enhancing the psychological resilience of emergency first-responders. Participants were randomly allocated to either the Cognitive Reframing group or the MBSR group. After six weeks, their resilience was measured using a standardised psychometric scale.
