Fatigue among Patients with Type 2 Diabetes Mellitus: The Impact of Spirituality and Illness Perceptions

Type 2 Diabetes Mellitus (T2DM) can cause fatigue, negatively affecting the daily functioning and health of individuals. The purpose of this study was to investigate the impact of spirituality and illness perceptions on fatigue among patients with Type 2 Diabetes Mellitus. In this cross-sectional, descriptive study, 100 patients with Type 2 Diabetes Mellitus completed the Fatigue Assessment Scale, the FACIT Sp-12 scale, and the Illness Perception Questionnaire-Revised assessing fatigue, spirituality, and illness perceptions, respectively. The mean age of the sample was 52.18 +/- 15.53 years and 65% were insulin-treated patients. The mean score for the FACIT Sp-12 scale was 31.86 +/- 7.7, for the FAS 27.0 +/- 7.63, and for the Consequences and Emotional Representations of IPQ-R 25.5 +/- 5.3. Statistically negative significant correlations were observed between the FACIT Sp-12 total score and the FAS subscales (r = -0.44 to -0.48, p < 0.01) and positive correlations between the "IP-Consequences and Emotional Representations" subscales and FAS scores. The total score of the FACIT Sp-12 (beta = -0.35) was a negative predictor while Consequences and Emotional Representations (beta = 0.28) were positive predictors of the total FAS Score. Participants scored moderate levels of total fatigue. Spirituality and positive illness perceptions may have a protective effect on the fatigue of patients with Type 2 Diabetes Mellitus.
