Posttraumatic Growth Among Older Adults With Age-Related Macular Degeneration

Abstract

Introduction: The term “post-traumatic growth” describes positive outcomes that accrue from the struggle with highly challenging life circumstances. The purpose of this study is to describe post-traumatic growth accruing from experience with vision loss caused by age-related macular degeneration (AMD) and to identify the relationships between depression, cognitive processing, social support, and post-traumatic growth. Methods: Individuals with vision loss caused by AMD completed an interviewer-administered composite questionnaire to identify elements of Tedeschi and Calhoun’s theoretical model of the process of posttraumatic growth, including measures of distress (depression), intrusive and deliberate rumination (cognitive processing), and social support (quality and quantity of social ties). Relationships were examined using path analysis. Results: Eighty-nine participants completed the questionnaire (mean age = 85.3 years, range = 74–98 years). All paths, including from depression to social support (β = –.363, p < .001), from social support to deliberate rumination (β = .233; p ≤ .01), and from intrusive rumination to deliberate rumination (β = .514, p < .01), were significant and consistent with the posttraumatic growth theoretical model. Deliberate rumination had a significant direct path to post-traumatic growth (β = .38, p = .001). Discussion: The findings may illuminate elements of the process of post-traumatic growth among those with AMD. We found that as social support increased, depression decreased. Increased social support seemed to encourage positive deliberate rumination, which led directly to post-traumatic growth. Although intrusive rumination is often associated with negative outcomes, the model demonstrates that it also stimulates engagement in deliberate attempts to process one’s experience. Deliberate cognitive processing is a direct precursor to post-traumatic growth. Implications for Practitioners: A focus on the process of growth and thriving can offer a broader view of the experience of living with vision loss. Interventions that foster post-traumatic growth among those with AMD should focus on enhancing social support and facilitating deliberate cognitive processing.
