Effects of hurricane harvey on trajectories of hostile conflict among newlywed couples.

Natural disasters have been purported to increase, and decrease, hostile conflict in intimate relationships, but heavy reliance on retrospective designs prohibits strong tests of these contrasting perspectives. The present study aims to resolve this ambiguity using a sample of newlywed couples from Houston, Texas who reported their levels of hostile conflict three times before and three times after experiencing Hurricane Harvey. Latent growth curve piecewise regression models showed that robust declines in conflict prior to the hurricane were slowed after the hurricane hit, such that posthurricane conflict slopes flattened and became nonsignificant. Thus, by disrupting natural declines in conflict that occur in the early years of marriage, Hurricane Harvey appears to have been detrimental for couples. Factors examined in relation to hostile conflict (including personality traits, adverse childhood events, stress, and relationship satisfaction) were similar in their predictive power prior to and following the hurricane, suggesting that the hurricane did not markedly alter which couples were most prone to hostile interactions. Implications for understanding relationships in the context of natural disasters are outlined. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
