Perceived and actual posttraumatic growth in religiousness and spirituality following disasters.

Objective: Religious/spiritual (R/S) growth is a core domain of posttraumatic growth (PTG). However, research on R/S growth following disasters has over-relied on retrospective self-reports of growth. We therefore examined longitudinal change in religiousness/spirituality following two disasters.

Method: Religious survivors of Hurricanes Harvey (Study 1) and Irma (Study 2) completed measures of perceived R/S PTG, general religiousness/spirituality ("current standing"-R/S PTG), and subfacets of religiousness/spirituality (spiritual fortitude, religious motivations, and benevolent theodicies). In Study 1, 451 participants responded at 1-month and 2-month postdisaster. In Study 2, participants responded within 5-days predisaster and at 1-month (N = 1,144) and 6-months postdisaster (N = 684).

Results: In both studies, perceived R/S PTG was weakly related to longitudinal increases in general religiousness/spirituality and in most of its subfacets, but reliable growth in any R/S outcome was rare. Additionally, Study 2 revealed evidence that actual change in psychological well-being is associated with actual (but not perceived) R/S PTG, but disaster survivors tend to exhibit declines in their religiousness/spirituality, spiritual fortitude, and religious motivations.

Conclusions: Results suggest disaster survivors are only modestly accurate in perceiving how much positive R/S change they experience following a disaster. We discuss implications for clinical practice, scientific research, and empirical and conceptual work on PTG more broadly.
