Aim: This study aimed to investigate the feasibility of implementing a psychological first aid intervention for psychological distress, resilience capacity, quality and meaning of life among survivors affected by earthquake adversity in Northern Syria. Methods: A quasi‐experimental, pre‐posttest, two‐group research design was utilized. A convenience sample of 95 survivors (46 in the study group and 49 in the control group) was recruited for the psychological First Aid intervention at a 1:1 ratio. The psychological first aid intervention was delivered in 10 sessions, twice weekly, followed by 3‐month follow‐up. Results: A statistically significant improvement in the mean scores of resilience capacity, quality and meaning of life among survivors, along with a significant reduction in psychological distress, was registered among the study group compared with the control group. Conclusion: Our work verified the suitability of implementing psychological first aid following the catastrophic temblors which struck Northern Syria. Given that the psychological first aid intervention is grounded in psychological safety, cognitive reframing, mobilization of social support and installation of hope, the feasibility of its path following public health emergency, traumatic events or even a personal crisis can be favourable. Summary statement: What is already known about this topic? On 6 February 2023, a massive earthquake devastated large portions of war‐torn northwest Syria and southern Turkey, leaving millions in these regions battling to reconstruct their lives.In northwest Syria, strong aftershocks left more than 4500 people dead, injured hundreds more and demolished at least 10 000 structures.Disasters such as earthquakes can have a significant impact on the mental health and well‐being of those affected. Survivors may experience high levels of psychological distress and other negative mental health recovery outcomes.There is a need for psychologically supportive interventions such as the psychological first aid intervention to help survivors cope with the aftermath of such disasters.What this paper adds? A statistically significant improvement in the mean scores of resilience capacity, quality and meaning of life among survivors, along with a significant reduction in psychological distress, was registered among the study group compared to the control group.Our work verified the suitability of implementing the psychological first aid intervention following the catastrophic temblors which struck Northern Syria.The implications of this paper: Being ready for disasters is critical; health care professionals, including nurses, are one of the most frequently requested actors in disaster interventions.Nurses are an indispensable part in ascertaining the psychological repercussions of disasters on survivors, families and communities.Due to their training and professional experience, nurses can take the lead in reducing health‐threatening risks.
