Resilience to Major Life Stressors Is Not as Common as Thought.

ABSTRACT: We attempted to replicate findings that "most people are resilient" following three events: spousal loss, divorce, and unemployment. We applied growth mixture models to the same longitudinal data set that has previously been used to assert that resilience is ubiquitous. When using identical model specifications, as in prior studies, we found that resilient trajectories were most common, but the number of trajectories identified was different. When we relaxed two assumptions used in prior studies-that (a) all classes have similar variability in levels of postadversity adjustment and (b) there is no variability in changes within classes-we found that a resilience class was least common. Methodologically, our results show how findings on trajectories of change following major life stressors can vary substantially, depending on statistical model specifications. Conceptually, the results underscore the errors inherent in any categorical statements about "rates of resilience" among individuals confronted with major life stressors. Pragmatically, they underscore the dangers in recommending against prophylactic interventions (on the basis of one method of analyzing longitudinal data) for individuals who have experienced major life stressors.

Project description:BackgroundAccording to the stress inoculation hypothesis, successfully navigating life stressors may improve one's ability to cope with subsequent stressors, thereby increasing psychiatric resilience.AimsAmong individuals with no baseline history of post-traumatic stress disorder (PTSD) and/or major depressive disorder (MDD), to determine whether a history of a stressful life event protected participants against the development of PTSD and/or MDD after a natural disaster.MethodAnalyses utilised data from a multiwave, prospective cohort study of adult Chilean primary care attendees (years 2003-2011; n = 1160). At baseline, participants completed the Composite International Diagnostic Interview (CIDI), a comprehensive psychiatric diagnostic instrument, and the List of Threatening Experiences, a 12-item questionnaire that measures major stressful life events. During the study (2010), the sixth most powerful earthquake on record struck Chile. One year later (2011), the CIDI was re-administered to assess post-disaster PTSD and/or MDD.ResultsMarginal structural logistic regressions indicated that for every one-unit increase in the number of pre-disaster stressors, the odds of developing post-disaster PTSD or MDD increased (OR = 1.21, 95% CI 1.08-1.37, and OR = 1.16, 95% CI 1.06-1.27 respectively). When categorising pre-disaster stressors, individuals with four or more stressors (compared with no stressors) had higher odds of developing post-disaster PTSD (OR = 2.77, 95% CI 1.52-5.04), and a dose-response relationship between pre-disaster stressors and post-disaster MDD was found.ConclusionsIn contrast to the stress inoculation hypothesis, results indicated that experiencing multiple stressors increased the vulnerability to developing PTSD and/or MDD after a natural disaster. Increased knowledge regarding the individual variations of these disorders is essential to inform targeted mental health interventions after a natural disaster, especially in under-studied populations.
