Exercise Self-efficacy In Patients Research Articles

Effect of Multimedia Messaging Service on Exercise Self-efficacy in Diabetic Patients.

Objectives: To increase patients' self-efficacy for initiation of physical activity, there is a need to include physical activity into patient education in clinic settings. In this study, we aimed to assess the effectiveness of multimedia messaging service (MMS) education on exercise self-efficacy in patients with type 2 diabetes mellitus (T2DM). Methods: We used a quasi-experimental, pretest-posttest design to study 98 patients with T2DM. The intervention group received MMS education targeting exercise self-efficacy for 2 months, and the control group received routine care only. Patients in both groups completed the Exercise Self-efficacy scale at 3 stages (at baseline, at 4 weeks, and at 8 weeks post-intervention). Results: We found a slight increase between baseline, first follow-up, and second follow-up in interpersonal and competing demands factors in the intervention group (p = .002, p = .001, respectively), but no improvement in the control group in any of the 3 factors over time (p > .05). Also, Cohen's d values indicated a medium effect size in all exercise self-efficacy subscales (interpersonal [0.734], competing demands [0.665], and internal feelings [0.696]). Conclusions: Health education using theoretically-based MMS targeting exercise self-efficacy was effective and affordable in promoting and changing patients' beliefs and physical activity behaviors.

Validity and reliability of the Iranian version of the Cardiac Exercise Self-Efficacy Scale.

BACKGROUNDThe assessment of exercise self-efficacy in patients with cardiovascular disease (CVD) is necessary to conduct tailored interventions. The aim of the current study was to validate the Iranian version of the Cardiac Exercise Self-efficacy Scale (CESE) for patients with CVD.METHODSTo develop the Iranian version of the CESE scale, a forward and back translation procedure was followed. Data were collected from 260 patients with CVD who were admitted to Imam Ali Cardiovascular Hospital, Iran, using convenience sampling. Psychometric properties of the scale including validity (face and content validity, discriminant, concurrent, convergent, divergent, and construct validity) and reliability (internal consistency, and test-retest reliability) were assessed. SPSS software was used for statistical analysis.RESULTSThe questionnaire had a good face and content validity and reliability, with Cronbach's alpha of 0.87 and intraclass correlation coefficient (ICC) of 0.42. The questionnaire discriminated well between subgroups according to their medical conditions and the “health transition” item in the Short-Form Health Survey (SF-36). There was a significant correlation between CESE and the physical components of the SF-36 (P < 0.001). In addition, a strong to moderate significant correlation was found between the CESE and the Exercise Self-efficacy Scale (ESES) (r = 0.77; P < 0.01) and between CESE and the Hospital Anxiety and Depression Scale (HADS) total (r = -0.45; P < 0.001). The exploratory factor analysis (EFA) identified a four-factor structure model, explaining 71.02% of the observed variance.CONCLUSIONThe Persian version of the CESE is a valid and reliable instrument for the evaluation of CVD patients’ exercise self-efficacy level in performing regular exercise behaviors.

Reliablity and validity of Chinese Version of the Exercise Self-Efficacy Scale in patients after stroke

Objective To translate the English version of the Exercise Self-Efficacy Scale (ESES) into Chinese and test the reliability and validity of the Chinese version of ESES in patients after stroke. Methods Totally 214 patients after stroke were recruited and were investigated by the Chinese version of ESES. Results The internal consistency coefficient of the Chinese version of ESES was 0.879. The split half reliability coefficient was 0.858(P <0.01). The test-retest reliability was 0.657. Item-total correlation coefficient ranged between 0.627 and 0.779 (P <0.01). Factor analysis got one factor, which explained 59.745% of the total variance, and the factor loading of each item was above 0.4. Using General Perceived Self-Efficacy Scale (GSES) as an external criterion, the Pearson correlation coefficient of ESES with GSES was 0.496. Conclusions The Chinese version of ESES has been proved to be reliable and valid. It can be used as a valid tool for the measurement of exercise self-efficacy in patients after stroke.

Social support as a predictor of diet and exercise self-efficacy in patients with coronary artery disease

Objectives: This study examined the role of social support and other factors in relation to exercise and diet self-efficacy in Chinese patients with coronary heart disease in Hong Kong.Methods: A cross-sectional study was conducted on a convenience sample identified from two cardiac rehabilitation centers. Eighty-five participants joined the study.Results: Both self-efficacy measures correlated with social support, in particular in the domains of emotional/informational support and positive social interactions. Stronger social support was independently associated with a higher level of exercise and diet self-efficacy. Patients with a higher body mass index had a lower level of exercise self-efficacy, whereas social drinkers had a lower level of diet self-efficacy.Conclusions: Our data supported an association between social support and self-efficacy. It was suggested that social companions would help patients get greater confidence in overcoming barriers to lifestyle modification. Further studies may investigate what type of social support contributes to improving the self-efficacy beliefs of patients.

Tai Chi Exercise in Patients With Chronic Heart Failure

Preliminary evidence suggests that meditative exercise may have benefits for patients with chronic systolic heart failure (HF); this has not been rigorously tested in a large clinical sample. We sought to investigate whether tai chi, as an adjunct to standard care, improves functional capacity and quality of life in patients with HF. A single-blind, multisite, parallel-group, randomized controlled trial evaluated 100 outpatients with systolic HF (New York Heart Association class I-III, left ventricular ejection fraction ≤40%) who were recruited between May 1, 2005, and September 30, 2008. A group-based 12-week tai chi exercise program (n = 50) or time-matched education (n = 50, control group) was conducted. Outcome measures included exercise capacity (6- minute walk test and peak oxygen uptake) and disease-specific quality of life (Minnesota Living With Heart Failure Questionnaire). Mean (SD) age of patients was 67 (11) years; baseline values were left ventricular ejection fraction, 29% (8%) and peak oxygen uptake, 13.5 mL/kg/min; the median New York Heart Association class of HF was class II. At completion of the study, there were no significant differences in change in 6-minute walk distance and peak oxygen uptake (median change [first quartile, third quartile], 35 [-2, 51] vs 2 [-7, 54] meters, P = .95; and 1.1 [-1.1, 1.5] vs -0.5 [-1.2, 1.8] mL/kg/min, P = .81) when comparing tai chi and control groups; however, patients in the tai chi group had greater improvements in quality of life (Minnesota Living With Heart Failure Questionnaire, -19 [-23, -3] vs 1 [-16, 3], P = .02). Improvements with tai chi were also seen in exercise self-efficacy (Cardiac Exercise Self-efficacy Instrument, 0.1 [0.1, 0.6] vs -0.3 [-0.5, 0.2], P < .001) and mood (Profile of Mood States total mood disturbance, -6 [-17, 1] vs -1 [-13, 10], P = .01). Tai chi exercise may improve quality of life, mood, and exercise self-efficacy in patients with HF. Trial Registration clinicaltrials.gov Identifier: NCT00110227.

The study of correlation between exercise self-efficacy and physical exercise in patients with type 2 diabetes

Objective To describe exercise self-efficacy in patients with type 2 diabetes and to examine the relationship between exercise serf-efficacy and physical exercise. Methods A convenience sample of 117 patients with type 2 diabetes was interviewed, using Exercise Self-Efficacy Scale and Leisure Time Physical Activity Questionnaire(LPAQ). Results The average score of exercise self-efficacy in patients with type 2 diabetes was (52.42 ± 18.30) (a range of average score is 0 ～ 100). There was significantly positive relationship between exercise self-efficacy and the time of physical exercise (r =0. 415, P <0. 01) ; there was significantly positive relationship between exercise serf-efficacy and the energy expenditure of physical exercise (r = 0. 452, P < 0. 01). Conclusions Patients with type 2 diabetes had moderate level of exercise selfefficacy. The higher the patients' exercise self-efficacy, the more the time of physical exercise, the more the energy expenditure of physical exercise.
