Stress and Growth in Cancer: Mechanisms and Psychotherapeutic Interventions to Facilitate a Constructive Balance

Abstract

Post-traumatic stress and growth are common responses to adverse life events such as cancer. In this article, we establish how cancer becomes a “fertile land” for the emergence of stress and growth responses and analyze the main mechanisms involved. Stress-growth responses on adjusting to cancer is potentially determined by factors like the phase of the illness (e.g., initial phases vs. period of survivorship), patient’s coping strategies, meaning-making, and relationships with significant others. We also review the mechanisms of constructive and adaptative stress-growth balances in cancer to study the predictors, interrelated associations, triggering mechanisms, long-term results, and specific trajectories of these two responses to cancer. Finally, we update the evidence on the role of these stress-growth associations in psychologically adjusting to cancer. Together with this evidence, we summarize preliminary results regarding the efficacy of psychotherapeutic interventions that aim to facilitate a constructive psychological balance between stress and growth in cancer patients. Recommendations for future research and gaps in knowledge on stress-growth processes in this illness are also highlighted. Researchers are encouraged to design and use psychotherapeutic interventions according to the dynamic and changeable patients’ sources of stress and growth along the illness. Relevant insights are proposed to understand the inconsistency of stress-growth literature and to promote psychotherapeutic interventions to facilitate a constructive balance between these key responses in cancer.

Women's Contexts and Circumstances of Posttraumatic Growth After Sexual Victimization: A Systematic Review

“…Tedeschi et al and associates 2018 distinguished between resilience (i.e., a person's intrapersonal attributes) and PTG, which is the result of permanent change in the aftermath of one or several traumatic events. The vast majority of research to date has focused on medical illness such as cancer (Ochoa Arnedo et al, 2019), natural disasters (e.g., hurricanes) (Hafstad et al, 2011), terror (Eisenberg and Silver, 2011) and war-related violence among affected individuals such as military personnel (Nordstrand et al, 2020). More recently, PTG research included domestic and family violence (DFV) including sexual violence (D'Amore et al, 2018).…”

Pandemic-Driven Posttraumatic Growth for Organizations and Individuals

“…5 Studies conducted with patients who have or had cancer demonstrated that interventions designed to facilitate posttraumatic growth resulted in a statistically significant improvement relative to controls, with 1 study involving 126 patients with cancer showing posttraumatic growth sustained at 1 year. 6 In facilitating posttraumatic growth, it may be possible to reduce the negative influence of future psychological traumas and potentially create a more resilient health care workforce and stronger health care organizations. When the Swedish Health System in Seattle became an epicenter for some of the first cases of COVID-19 in the United States, they attributed their preparedness and resilience to deliberate reflection, learning, and growth catalyzed by a major labor strike several months earlier.…”

“…We also incorporate in our analysis of PTG, the new knowledge and methods to interpret the productive and illusory part of this potential therapeutic response. [36][37][38]…”
