Abstract [en]

AIMS AND OBJECTIVES: The aim of the present study was twofold: 1) to measure changes in health-related quality of life (HRQoL), two dimensions of illness perceptions (i.e., consequences and emotional representations), fatigue and self-efficacy in persons treated for CRC during the first year after surgical treatment, and 2) to study how fatigue, illness perceptions and self-efficacy measured at 3 months affect HRQoL at 12 months post-surgery.

BACKGROUND: There are fluctuations in HRQoL during the first year after treatment for colorectal cancer (CRC), and fatigue may negatively influence HRQoL. Illness perceptions (consequences and emotional representations) and self-efficacy have been shown to be associated with HRQoL in other cancer diagnoses. Concerning CRC, there is a lack of knowledge concerning how illness perceptions and self-efficacy change during recovery, and how these variables and fatigue at 3 months relate to HRQoL at 12 months.

DESIGN: A prospective longitudinal design.

METHODS: Thirty-nine persons surgically treated for colorectal cancer, of whom 17 had a colostoma, participated. HRQoL, fatigue, illness perceptions and self-efficacy were assessed using QLQ-C30, the Revised Illness Perception Questionnaire and the Maintain Function Scale. Descriptive and analytical statistics were used.

RESULTS: No changes were reported in levels of HRQoL, fatigue, or illness perceptions. Self-efficacy was lower at 12 months compared to 3 months. Fatigue and one dimension of illness perceptions mediated the effect of self-efficacy at 3 months on HRQoL at 12 months.

CONCLUSION: Persons treated for CRC who have lower self-efficacy 3 months post-surgery are inclined to have more negative illness perceptions concerning emotions and to experience more fatigue.

RELEVANCE TO CLINICAL PRACTICE: Nurses need to support persons with fatigue and negative illness perceptions concerning emotions and to bolster their self-efficacy, i.e., carry out follow-up consultations focusing on illness management, symptoms, emotions and information on ways to increase self-efficacy.
