Hanan, S.A. and Sahar Y.M. (2011), Egypt | To compare perceived self-efficacy, exercise benefits, exercise barriers, and commitment to exercise between patients diagnosed with osteoporosis and osteoarthritis, and to assess the influence of perceived exercise self-efficacy, exercise benefits, and barriers on commitment | Comparative cross-sectional design | Perceived self-efficacy, exercise benefits, exercise barriers, and commitment to a plan | Perceived self-efficacy―perceived exercise self-efficacy scale, Bandura (1997), Perceived benefits and barriers to exercise―exercise benefits and barriers scale Sechrist, et al. (1987), Commitment to a plan-commitment to a plan for exercise scale, Pender (1996), and adherence to the exercise―exercise documentation record (developed by the researchers) | 75 patients with a clinical diagnosis of osteoporosis and 75 patients with osteoarthritis at the Maternity Hospital, and Ain Shams University Hospitals in Egypt | Osteoporotic patients had significantly of commitment to plan and exercise self-efficacy, while exercise benefit was higher in the osteoarthritis group (P< 0.001). In addition, significant positive correlations were found between commitment and perceived self-efficacy scores, and between self-efficacy and perceived lack of barriers and exercise benefits in both groups (P< 0.001). Age was a negative predictor for commitment in osteoporosis group, while self-efficacy and lack of barriers were positive predictors. In osteoarthritis group, self-efficacy was the only positive predictor of commitment |
Khalil et al. (2012), Jordan | To provide insight into the relationship between dietary and fluid nonadherence, depressive symptoms, quality of life, perceived barriers and benefits of exercise, and perceived social support among patients with end-stage renal disease receiving hemodialysis | A descriptive, correlational, cross-sectional design | Dietary and fluid nonadherence, depressive symptoms, quality of life, perceived barriers and benefits of exercise, and perceived social support | Diet and fluid non-adherence―the dialysis diet and fluid nonadherence questionnaire (DDFQ), (Vlaminck, et al., 2001), Depressive symptoms―the beck depression inventory-II (BDI-II), (Beck, et al., 1996), Perceived quality of life―the quality of life index (QLI), (Ferrans & Powers, 1985), Perception of dialysis patients regarding exercise benefits and barriers―the dialysis patient-perceived exercise benefits and barriers scale (DPEBBS), (Zheng, et al., 2009), and perceived social support―the multidimensional perceived social support scale (Zimet, et al., 1988) | A convenience sample of 190 patients diagnosed with ESRD and being dialyzed in three major cities in Jordan: Amman, Zarqa and Irbid | ESRD patients showed full commitment to diet guidelines and to fluid guidelines. Depression had significant negative association with quality of life (importance and satisfaction) (r = −0.60, r = −0.32, P = 0.001, respectively). Results also revealed a predictive model of only two variables: age (Β = −0.22, P = 0.05) and residual renal function for dietary non-adherence (B = −0.23, P = 0.012) |
