Abstract

Background: As a chronic disease, heart failure (HF) is a growing problem that not only impacts patients but also their family members and friends. Self-care is the main part of HF treatment. Despite the significance of determining variables involved in self-care, the relationships of self-efficacy, illness perception, and social support with self-care and the predictive roles of these variables in the treatment of HF have not been investigated.
Objectives: The present study was aimed at exploring the predictive roles of self-efficacy, illness perception, and social support in self-care of patients with heart failure.
Methods: In this predictive correlation study, 149 patients with HF were selected through convenience sampling from Tabriz Research Treatment Centre of Heart in 2016. To collect data, a demographic information questionnaire, self-care behaviour scale, general self-efficacy (GSE), brief illness perception questionnaire (Brief-IPQ), and social support scale were used. To analyse data, SPSS software version 16, descriptive statistics, Pearson correlation coefficient, and multiple stepwise regression analyses were employed.
Results: Out of 149 subjects, 102 (68%) participants were male, and 47 (32%) of them were female. The mean and standard deviation of samples’ age were (64.40±10.32) ranging from 37 to 88 years. Most of participants were married (82%). The mean scores were as follows: Self-care (40.66±13.16), self-efficacy (45.81±22.03), illness perception (56.05±18.24), and social support (49.09±6.74). Data analysis demonstrated significant correlations between illness perception and self-care (p<0.001, r=0.649), self-efficacy and self-care (p<0.001, r=-0.678), social support and self-care (p<0.001, r=-0.518), and age and self-care (p<0.001, r=-0.506). The standardized coefficient of illness perception was (β=0.274), social support was (β=-0.237), self-efficacy was (β=-0.230), and age was (β=-0.211). In addition, 56% of self-care variance is explained by age, social support, self-efficacy, and illness perception.
Conclusion: All of the investigated variables were found to have a predictive role in self-care. Illness perception was recognized as the most effective factor in predicting self-care. Hence, illness perception can be used to explain 27% of self-care ability of patients with HF.

Abstract

Background: Nutrition education is a key component of health promotion programs and leads to the improvement of nutritional behaviors of adolescents. Understanding the stages of cognitive-behavioral therapy in eating behavior and weight loss in adolescents is important in terms of preventive care.
Objectives: The purpose of this study was to determine the effectiveness of cognitive-behavioral therapy on eating behavior and weight loss in adolescents.
Methods: The research method was semi-experimental with a pre-test and post-test design with a two-month follow-up with the control group. The statistical population consisted of all adolescents referred to counseling centers in Mashhad in autumn 2019; 30 of them were selected by convenience sampling method and were randomly divided into experimental, and control groups. The research questionnaires were demographic questionnaire, and eating behavior questionnaire. Data were analyzed using repeated variance analysis and SPSS.22 software.
Results: The mean (SD) of age was 17.66 (4.49) years in the experimental group 59.7% and 17.01 (4.10) years in the control group. 65.9% in the experimental group and in the control group, 59.7% were girls and the mean (SD) of body mass index was 27.73 (1.34) in the experimental group and 27.32 (0.95) in the control group. The results showed that cognitive-behavioral therapy was effective in decreasing uncontrollable eating (P<0.01), emotional eating (P<0.01), weight loss (P<0.01), and increasing cognitive restraint (P<0.01) in adolescents.
Conclusion: It is concluded that cognitive-behavioral therapy can be used as an effective treatment of weight loss and eating behavior in adolescents.
