Post-traumatic growth in the military: a systematic review

Background

Post-traumatic growth is defined as positive psychological, social or spiritual growth after a trauma.

Objectives

This systematic review aimed to identify studies that quantitatively measured post-traumatic growth among (ex-) military personnel, to determine whether there is evidence of growth in this context and whether such growth is associated with any sociodemographic, military, trauma or mental health factors.

Data sources

The electronic databases PsycInfo, OVIDmedline and Embase were searched for studies published between 2001 and 2017.

Study eligibility criteria and participants

Papers were retained if they involved military or ex-military personnel, where some had been deployed to Iraq or Afghanistan.

Study appraisal

Quality assessment was conducted on all studies.

Results

21 studies were retained. The Post-Traumatic Growth Inventory was employed by 14 studies: means ranged from 32.60 (standard deviation = 14.88) to 59.07 (23.48). The Post-Traumatic Growth Inventory Short Form was used by five studies: means ranged from 17.11 (14.88) to 20.40 (11.88). These values suggest moderate growth. Higher levels of social support, spirituality and rumination and minority ethnicity were most frequently associated with more post-traumatic growth.

Limitations

The involved studies may lack generalisability and methodological quality.

Conclusions

Overall, this paper confirms that negative reactions to trauma, particularly post-traumatic stress disorder, are not the only possible outcomes for service personnel, as moderate post-traumatic growth can also be observed.

Implications of key findings

Interventions aimed at helping current and former armed forces personnel to identify and promote post-traumatic growth post-conflict may be beneficial for their well-being.
