Affect and psychological well-being in spouses of cancer patients: the mediating role of meaning in life and self-efficacy

The examination of the psychological functioning of cancer patients’ spouses implies that affect and personal resources play an important role in their psychological well-being. This is a consequence of the severe stress caused by the medical conditions of a spouse and of responsibilities related to caregiving. This study aimed to examine the role of affect and purpose-oriented personal resources (meaning in life and self-efficacy) in shaping psychological well-being in the spouses of cancer patients. The participants were 214 spouses of gastrointestinal patients who were either undergoing medical treatment in hospital units or attending scheduled clinic appointments at outpatient medical clinics. The Positive and Negative Affect Schedule (PANAS-X), Psychological Well-Being Scale (PWB), Meaning in Life Questionnaire (MLQ), and General Self-Efficacy Scale (GSES) were used. The results indicated that positive affect was positively correlated with meaning in life, self-efficacy, and psychological well-being. In contrast, negative affect was negatively correlated with positive affect, meaning in life, self-efficacy, and psychological well-being. The mediation analyses demonstrated that meaning in life and self-efficacy were mediators between positive and negative affect and psychological well-being. The mediating function of meaning in life and self-efficacy revealed the significant role of personal resources based on purpose and self-motivation in the relationship between affect and psychological well-being. Positive and negative affect can influence motivational processes that enable patients and their families to constructively deal with challenging and illness-related situations. Caregivers and medical staff could take into account the important role of purpose-oriented resources as they affect the functioning of both patients and their families.
