The relationship between post-traumatic stress and negative emotions in patients with breast cancer: the mediating role of emotion regulation

ABSTRACT

Purpose:

Negative emotions can adversely affect the treatment and recovery of breast cancer patients. Post-traumatic stress caused by cancer can increase the negative emotions of patients. This study assessed the relationship between post-traumatic stress and emotional regulation strategies, and the role of emotional regulation in the relationship between post-traumatic stress and negative emotions in breast cancer patients.

Design:

Cross-sectional questionnaire with sample of 214 Chinese women with breast cancer

Methods:

Participants completed the Impact of Event Scale-Revised, Hospital Anxiety and Depression Scale, and Emotion Regulation Questionnaire. Correlation and mediation analyses were conducted to assess associations among the scores of these scales.

Findings:

Patients with low post-traumatic stress chose cognitive reappraisal strategies, while those with high post-traumatic stress chose expressive suppression strategies. Cognitive reappraisal had a significant negative predictive effect on negative emotions, while expressive suppression had a significant positive predictive effect on patient’s negative emotions.

Conclusions:

Cognitive reappraisal may reduce the impact of post-traumatic stress on negative emotions experienced by breast cancer patients. Implications for psychosocial providers or policy: Psychosocial workers in China should conduct cognitive reappraisal training for breast cancer patients with high negative emotions and severe post-traumatic stress. For Chinese breast cancer patients living in other regions, the local oncology social workers should take into account their cultural background and lack of expression, and encourage them to choose cognitive reappraisal strategies.
