Effect of the Theory-driven Educational Intervention on Self-Care Behavior and Glycosylated Hemoglobin Level in Patients with Type 2 Diabetes.

BACKGROUND AND AIMS: The diabetics' lack of knowledge about self-care and incorrect beliefs in this care are the reasons for their admission to hospitals. The present study aimed to examine the impact of education based on the theory of planned behavior (TPB) on intention, self-care behavior, and glycosylated hemoglobin (HbA1c) levels in patients with Type 2 Diabetes. METHODS: The present study was conducted on 60 diabetic patients who were randomly classified into intervention and control groups. In the intervention group, self-care education based on TPB was held, but the control group only received routine care. The data were collected using a fourpart questionnaire including characteristics, items of patients' knowledge, items of TPB constructs, and items of diabetes self-care. Data were analyzed in SPSS software. RESULTS: In intervention group, mean score of self-care behavior and its domains significantly changed from (total: 52.26±14.75, diabetic diet: 22.20±6.05, exercise: 5.17±4.04, blood sugar testing: 5.03 ± 4.15, medication: 5.40±2.28, foot care: 13.47±8.42) into 76.66±8.87, 29.43±5.48, 7.60±2.60, 8.73±2.31, 6.48±1.09, 23.53±3.09, respectively three months after intervention (p<0.01). In this case, these changes were not seen in the control group. The mean level of HbA1c in the intervention group (6.38±0.16) was significantly lower than before the intervention (7.56±1.08) and the control group (8.02±0.25) three months after intervention(p<0.01). CONCLUSION: Education based on the TPB was effective in improving the patients' self-care behavior and HbA1c index. Therefore, we suggest all medical centers to use the TPB as an effective and low-cost educational approach to improve diabetics' self-care behavior and health.

A Study on the effect of lifestyle educational intervention based on the theory of planned behavior on promoting quality of life of middle-aged women.

The present study aimed to determine the effect of lifestyle educational intervention based on the theory of planned behavior on promoting the quality of life of middle-aged women. The present quasi-experimental study examined 80 middle-aged women and randomly divided them into two groups (intervention and control). Data collection tools included the demographic information questionnaire, the Health Promoting Lifestyle Profile-II (HPLP-II), the 12-Item Short-Form Health Survey (SF-12), and the author-developed questionnaire based on constructs of the theory of planned behavior. Data were collected via WhatsApp twice (before and three months after the educational intervention). Five 45-minute training sessions were held for the intervention group and a 60-minute session for a family member regarding physical activity and spiritual growth over two months via WhatsApp. Data were analyzed using SPSS, and the results were considered significant at a statistical level (p < .05). The implementation of the educational intervention significantly increased the mean scores of quality of life, physical activity and spiritual growth, knowledge regarding physical activity and spiritual growth, attitude toward physical activity and spiritual growth, subjective norms toward spiritual growth, perceived behavioral control for physical activity, and behavioral intention to perform physical activity and spiritual growth in the intervention group in comparison with the control group. The educational intervention, which was designed based on constructs of the theory of planned behavior, was influential in promoting the lifestyles and quality of life of middle-aged women. Therefore, it is suggested to use the educational program of the present study in addition to other middle-age health care.

Predictors of Smoking Preventive Behavior Based on Empowerment Components among Male Students of High Schools: A Cross-Sectional Study in Iran.

Background: Smoking among adolescents and young adults is believed to be one of the most important preventable health problems. The etiology of smoking is one of the most pivotal activities in designing prevention programs. The aim of this study was to determine the correlates between components of empowerment in the context of smoking prevention in adolescents. Methods: This cross-sectional descriptive study was carried out on 422 high school male students in spring 2020. The data collection tool of this study was a valid and reliable researcher-made questionnaire containing demographic characteristics, items related to various components of empowerment, and items related to the smoking preventive behavior (SPB). A linear regression model was used, where the "SPB" outcome variable assumed three possible values: sensation seeking, problem-solving skills, self-efficacy, self-esteem, dependence on group, and attitude towards smoking reported in the previous literature were taken as independent variables, and smoking preventive behavior was considered as a dependent variable. Results: The results revealed that 10.42% of the students were active smokers and 40.75% of them had the experience of smoking. The results also showed a positive and significant relationship between problem-solving skills (r = 0.394, P < 0.001), self-efficacy (r = 0.340, P < 0.001), self-esteem (r = 0.310, P < 0.001), and attitude (r = 0.333, P < 0.001) with the SPB. In addition, a negative and significant correlation was observed between group dependence (r = -0.313, P < 0.001) and the SPB. Overall, the components of empowerment were able to explain 26.5% of the variance in the SPB. Among the components, problem-solving skills solely explained 15.5% of variance of the SPB. Conclusion: According to the results of this study, it can be said that most adolescents are at risk of smoking. Explanatory factors for adopting the SPB include improving problem-solving skills, creating a negative attitude towards smoking, increasing self-efficacy to prevent smoking, reducing group dependence, and increasing self-esteem in adolescents. Multilevel interventions and actions by policymakers, educators, and related organizations to prevent adolescent smoking and educate them about adolescent empowerment skills to prevent smoking should be considered.

Predictors of colorectal cancer screening intention based on the integrated theory of planned behavior among the average-risk individuals.

BACKGROUND: This study aimed to determine the predictors of colorectal cancer screening intention based on the integrated theory of planned behavior among average -risk individuals in Urmia. Identifying these predictors will help design and implement various interventions, including educational interventions, according to the needs of this group, thereby taking a step towards improving the colorectal cancer screening index. METHODS: The present cross-sectional study was performed on 410 individuals at average risk of colorectal cancer referring to the comprehensive health services centers of Urmia in Iran. The data collection tool was a researcher-made questionnaire consisting of two parts. The first part captured the demographic information and medical history of the participants. The second part involved questions designed based on constructs of motivational phase of health action process approach, and theory of planned behavior, as well as behavioral intent to perform colorectal cancer screening. Data analysis was performed using SPSS software. RESULTS: Outcome expectancies, risk perception, action self-efficacy, and normative beliefs, respectively had the largest impact and were significant and positive predictors of colorectal cancer screening intention. The study's conceptual framework explained about 36% of the variance of behavioral intention among the average-risk individuals in Urmia. CONCLUSIONS: Constructs of motivational phase of health action process approach, and theory of planned behavior are valuable and appropriate to identify the factors affecting the intention to undergo colorectal cancer screening as well as to design and implement educational interventions in this field. The four constructs of outcome expectancies, risk perception, action self-efficacy, and normative beliefs are suggested to be integrated into all educational interventions designed and implemented to improve the colorectal cancer screening index.

Determining intention, fast food consumption and their related factors among university students by using a behavior change theory.

BACKGROUND: Today, with the advancement of science, technology and industry, people's lifestyles such as the pattern of people's food, have changed from traditional foods to fast foods. The aim of this survey was to examine and identify factors influencing intent to use fast foods and behavior of fast food intake among students based on the theory of planned behavior (TPB). METHODS: A cross-sectional study was conducted among 229 university students. The study sample was selected and entered to the study using stratified random sampling method. Data were collected using a four-part questionnaire including Participants' characteristics, knowledge, the TPB variables, and fast food consumption behavior. The study data were analyzed in SPSS software (version 16.0) using descriptive statistics (frequencies, Means, and Standard Deviation) and inferential statistics (t-test, Chi-square, correlation coefficient and multiple regressions). RESULTS: The monthly frequency of fast food consumption among students was reported 2.7 times. The TPB explained 35, 23% variance of intent to use fast food and behavior of fast food intake, respectively. Among the TPB variables, knowledge (r = .340, p < 0.001) and subjective norm (r = .318, p < 0.001) were known as important predictors of intention to consume fast foods - In addition, based on regression analyses, intention (r = .215, p < 0.05), perceived behavioral control (r = .205, p < 0.05), and knowledge (r = .127, p < 0.05) were related to fast food consumption, and these relationships were statistically significant. CONCLUSIONS: The current study showed that the TPB is a good theory in predicting intent to use fast food and the actual behavior. It is supposed that health educators use from the present study results in designing appropriate interventions to improve nutritional status of students.

The effect of patient education based on health belief model on hospital readmission preventive behaviors and readmission rate in patients with a primary diagnosis of acute coronary syndrome: a quasi-experimental study.

BACKGROUND: The health belief model is one of the applicable methods of training health preventive behaviors, especially in patients with cardiovascular diseases. Therefore, this study aimed to determine the effect of patient education based on the health belief model on readmission preventive behaviors and readmission rate in patients with a primary diagnosis of acute coronary syndrome. METHODS: The present quasi-experimental study was conducted in 2020 on patients with a primary diagnosis of acute coronary syndrome who were discharging from Seyed Al-Shohada Hospital, Urmia, Iran. In this study, a total of 70 samples were recruited using convenience sampling and then randomly assigned to two groups of intervention and control (n = 35 in each group). A total of 7 face-to-face group training sessions were held with the participation of the patients and one of their family members during 14 days after hospital discharge. These sessions were conducted along with concentration on the structures of the health belief model. Data were collected at three time points of immediately before, one month, and three months after the intervention using a demographic questionnaire, a researcher-made questionnaire of readmission preventive behaviors in cardiovascular diseases, and a checklist of hospital readmission. Data were analyzed using SPSS Statistics for Windows, version 17.0 (SPSS Inc., Chicago, Ill., USA). RESULTS: The results showed that there was a statistically significant difference in the mean score of preventive behaviors between the two groups at time points of one month and three months after the intervention (p < .05). However, there was no statistically significant difference in the readmission rate between the two groups after the intervention (p > .05). CONCLUSION: Health belief model-based education was shown to be effective on readmission preventive behaviors in patients with acute coronary syndrome, although this model had no effect on the readmission rate in these patients. Other factors affecting the readmission rate are recommended to be investigated.

Psychometric Properties of the Iranian version of Champion's Revised Health Belief Model Scale for Breast Cancer screening.

BACKGROUND: Women's beliefs regarding breast cancer and its screening approaches were considered antecedents of their behavioral changes. Understanding of these beliefs in women requires a valid and reliable instrument. The present study seeks to translate the English version of the Champion's Revised Health Belief Model Scale (CRHBMS) into the Persian language and assess its psychometric properties. MATERIALS AND METHODS: The study was conducted on 334 students at Urmia University of Medical Sciences, Iran, 2016. The 57-item CRHBMS was translated to Persian language, back translated, and tested. To test the face and content validity of the Persian version; item analysis, Content Validity Ratio (CVR), and Content Validity Index (CVI) were applied, respectively. Construct validity of the Persian scale was performed by Exploratory and Confirmatory Factor Analyses (EFA, CFA) using Kaiser-Meyer-Olkin and Bartlett's tests in SPSS 16 and LISREL8.72 software. The reliability of the translated scale was evaluated using Cronbach's alpha and test-retest approaches. RESULTS: In the EFA, eight factors were extracted concerning breast cancer screening, and each item was loaded on its specific factor. These factors were self-efficacy, health motivation, benefits-mammography, benefits-Breast Self-Examination (BSE), barriers-mammography, barriers-BSE, susceptibility, and severity. The final 42-item scale was confirmed by the CFA, and all goodness of fit indices showed a proper fit of the model. Cronbach's alpha coefficient and test-retest correlation of the subscales ranged from 0.72-0.89 and 0.67-0.93, respectively. CONCLUSIONS: The study suggests that the Persian version of CRHBMS is a feasible scale for evaluating women's health beliefs regarding breast cancer and its screening behaviors.

The impact of theory-based educational intervention on improving helmet use behavior among workers of cement factory, Iran.

BACKGROUND: The occurrence of occupational accidents is a serious public health issue in industrial workers and may impose life jeopardizing complications. The aim of the study was to assess the effect of a training intervention based on the theory of planned behavior (TPB) on helmet use of workers in cement factories in Khoy and Urmia, Northwest of Iran. MATERIALS AND METHODS: This study was a controlled quasi-experimental investigation (before and after) which was conducted on 170 workers employed in Khoy and Urmia cement factories, Northwest of Iran. Eighty-five eligible subjects from Khoy (as intervention group) and 85 similar samples from Urmia (as control group) were selected and recruited. A valid and reliable four-part questionnaire was used to collect the data including socio demographic information, awareness, the theory constructs, and the behavior. After completing the study questionnaire and needs assessment, a specific educational program was implemented on the intervention group only. The effects of education were compared between the groups before and after intervention. The posttest was applied 1 month after educational intervention. RESULTS: The mean age of workers in the intervention and control groups was 34.32 ± 8.19 and 33.62 ± 6.17 years, respectively. Before education, the mean score of awareness and helmet use behavior of intervention group was 6.15 ± 3.4 and 5.35 ± 2.8, but after education, those changed into 13.61 ± 3.10 and 9.15 ± 1.65, and the differences were significant (p < 0.01). In addition, before education, the mean score of attitude, subjective norm, behavioral control, and behavioral intention of intervention group was 27 ± 5.17, 37.74 ± 6.92, 29.56 ± 6.17, and 17.65 ± 4.90, respectively. After education, the mean score of those changed into 37.26 ± 4.76, 48.34 ± 5.64, 42 ± 8.07, and 24.79 ± 5.33, respectively, and changes were statistically significant (p < 0.01), while no statistically significant differences were observed in awareness, the behavior, and the theory constructs in the control group after the intervention. CONCLUSION AND RECOMMENDATIONS: The TPB-based educational approach had a remarkable effect on helmet use of workers. Applying this theory to improve workers' personal protective behaviors is recommended and emphasized.

Provider knowledge and performance in medication injection safety in anesthesia: A mixed method prospective crosses sectional study.

OBJECTIVES: Injection safety during anesthesia is a challenging health care issue in Iranian hospitals. Anesthesia is one of the most medication-intensive procedures in healthcare and injecting patients are an integral part of that care. The present study aimed to assess the status of medication injection safety practice in a teaching center. DESIGN, SETTING, PARTICIPANTS: A prospective cross-sectional study was done in 2014-2015 at a 500-bed secondary level teaching hospital affiliated with Urmia University of Medical Sciences, Iran. The study population included providers of anesthesia in two groups of operating rooms (ORs) with different types of surgeries at the center. Data were collected using valid and reliable observation and a questionnaire instruments in two consecutive phases. Mann-Whitney U, Kruskal-Wallis, and Spearman correlation tests were used for data analyses. RESULTS: A total of 345 injections were observed and recorded during the study period, 53% in group A ORs, and 47% in group B ORs. Eighty-two questionnaires were completed (96.5% response rate) to determine hospital injection practices and personal knowledge of injection safety. Adherence to safety requirements was observed in 58.5% of injections. Fifty five percent of respondents knew that hepatitis B, C, and HIV are blood borne diseases. Observed compliance with injection safety requirements was determined significant by OR groups (P = 0.00). Correlation was significant between observed injection safety practices by age and work experience (P = 0.00). The Kruskal-Wallis test showed a significant difference (P = 0.000) in observed safe injection practices among four job groups but not in reported adherence. Knowledge of respondents was significant by job groups about blood borne diseases and receiving three doses of hepatitis B vaccine. CONCLUSIONS: The study revealed that some of safe injection procedures were well carried out in our ORs, but that others were not. The reported adherence of staff was acceptable but their actual practices were unsafe. It is suggested to implement audits, provide safer supplies, and complete Hepatitis B vaccination of injection providers.

Psychosocial predictors of breast self-examination behavior among female students: an application of the health belief model using logistic regression.

BACKGROUND: Breast cancer is a life-threatening condition affecting women around the world. The early detection of breast lumps using a breast self-examination (BSE) is important for the prevention and control of this disease. The aim of this study was to examine BSE behavior and its predictive factors among female university students using the Health Belief Model (HBM). METHODS: This investigation was a cross-sectional survey carried out with 334 female students at Urmia University of Medical Sciences in the northwest of Iran. To collect the necessary data, researchers applied a valid and reliable three-part questionnaire. The data were analyzed using descriptive statistics and a chi-square test, in addition to multivariate logistic regression statistics in SPSS software version 16.0 (SPSS Inc., Chicago, IL, USA). RESULTS: The results indicated that 82 of the 334 participants (24.6%) reported practicing BSEs. Multivariate logistic regression analyses showed that high perceived severity [OR = 2.38, 95% CI = (1.02-5.54)], high perceived benefits [OR = 1.94, 95% CI = (1.09-3.46)], and high perceived self-efficacy [OR = 13.15, 95% CI = (3.64-47.51)] were better predictors of BSE behavior (P < 0.05) than low perceived severity, benefits, and self-efficacy. The findings also showed that a high level of knowledge compared to a low level of knowledge [OR = 5.51, 95% CI = (1.79-16.86)] and academic undergraduate and graduate degrees compared to doctoral degrees [OR = 2.90, 95% CI = (1.42-5.92)] of the participants were predictors of BSE performance (P < 0.05). CONCLUSIONS: The study revealed that the HBM constructs are able to predict BSE behavior. Among these constructs, self-efficacy was the most important predictor of the behavior. Interventions based on the constructs of perceived self-efficacy, benefits, and severity are recommended for increasing women's regular screening for breast cancer.

Health-Related Quality of Life and its Determinants Among Women With Diabetes Mellitus: A Cross-Sectional Analysis.

BACKGROUND: Diabetes is a chronic and threatening condition. However, there are controversies on the factors affecting the health related quality of life (HRQOL) in patients with diabetes. OBJECTIVES: The current study aimed to evaluate HRQOL and its determinants among females with type II diabetes referred to Diabetes Clinic of Khoy city, Northwest of Iran. PATIENTS AND METHODS: This cross-sectional study was performed on 352 eligible females with diabetes referring to Diabetes Clinic of Khoy. The study data were collected using a three-part instrument including a socio-demographic questionnaire, a questionnaire to assess patients' knowledge on diabetes and the world health organization's quality of life (WHOQOL-BREF) questionnaire. Based on descriptive and inferential statistics, analyses were conducted using frequency, independent samples t-test, correlation coefficient and regression analysis. RESULTS: The total mean score of QOL was 58.02 ± 17.63. The lowest and the highest mean scores were observed in physical health and social relationship domains (53.84 ± 17.09) and (65.08 ± 14.87), respectively. The regression models revealed that age, education, duration of disease, and family income were significantly associated with all areas of quality of life (P < 0.05). The results also revealed that co-morbidity was significantly correlated with the overall quality of life and the physical health domain (P < 0.01). CONCLUSIONS: The mean score of quality of life (QOL) in females with diabetes was far from desirable condition. These findings can help physicians and healthcare providers to design suitable interventions to improve the patients QOL.

Impact of Educational Intervention Based on Interactive Approaches on Beliefs, Behavior, Hemoglobin A1c, and Quality of Life in Diabetic Women.

BACKGROUND: Diabetes mellitus (DM) is a public health challenge worldwide and to manage it the patient is required to make some fundamental changes in behavior. Patients should be involved in care program to improve their diabetes condition and quality of life (QOL). This study aimed to examine the effect of educational program on beliefs, behavior, glycemic control indicator, and QOL among diabetic women. METHODS: In this interventional study, 90 female outpatients with type 2 diabetes were randomly selected from those referred to diabetes clinic in Khoy, Iran, during 2011. They were divided into two groups, 45 participants as the intervention group and 45 subjects as the comparison group. Knowledge, beliefs, and behavior by valid and reliable questionnaires, and health-related QOL (HRQOL) by means of WHOQOL-BREF questionnaire were assessed. Hemoglobin A1c level (HbA1c) was measured by the colorimetric method, educational program was conducted on the intervention group for 4 weeks, and changes were compared in two groups after a 3-month follow-up. RESULTS: After intervention, there was a significant difference between two groups in terms of the mean scores of knowledge (P < 0.001), attitude (P < 0.01), self-efficacy (P < 0.001), and behavior (P < 0.001). The findings also indicated that there were significant differences between the groups in mean scores of physical, psychological, and social domains of QOL after intervention (P < 0.001). In addition, there was a statistically significant difference between two groups in the mean value of HbA1c after educational intervention (P < 0.01). CONCLUSIONS: Instructional interventions based on interactive approaches can be useful, and applicable for behavior modification and improvement of HbA1c level and HRQOL in people with DM.

Dietary Patterns of Young Females and Their Association With Waist Circumference as a Health Index in Northwest of Iran, 2007.

BACKGROUND: Despite the higher prevalence of overweight and obesity among young people in western countries, the 50th and 95th percentile ranks for waist circumference in the Iranian young Females are higher than those of the western ones. OBJECTIVES: Identifying major dietary patterns in Iranian young females, which associate with central obesity, can probably explain the difference between Iranian young females' pattern and those of their western peers regarding obesity. PATIENTS AND METHODS: In the current cross-sectional study, a total of 257 young females aged 11 - 15 years old from Talaat Intelligent Guidance School, Tabriz, Iran (2007) were selected for the study using non-probability simple sampling method. Then, usual dietary intakes of all subjects were evaluated by a food frequency questionnaire and anthropometric measurements such as weight, height, waist circumference, and Body Mass Index (BMI) using the standard protocols. Data were analyzed by inferential statistics (One-way ANOVA, Tukey test for Post-Hoc Analysis, Chi-square test, age-adjusted means, analysis of covariance with Bonferroni correction, correlation and partial correlation) by SPSS software. RESULTS: In the current study, six major dietary patterns were extracted using factor analysis method. Before and after controlling the age, subjects in the upper tertile of the Iranian Central Obesity Making Dietary Pattern (rich in cruciferous vegetables, green leafy vegetables, soft drinks, tomatoes, other vegetables and vegetable oils) had larger waist circumference in comparison with the ones in the lower tertile (before controlling for age: 64.2 ± 9 vs. 61.6 ± 7 P = 0.03; after: 64.5 ± 0.8 vs. 61.5 ± 0.8, P = 0.009). However in lacto vegetarian dietary pattern (rich in legumes, potato, other vegetables, dough, high-fat dairy products and margarine), individuals in the upper tertile had significantly lower weight, waist circumference and body mass index (BMI) in comparison with the ones in the lower tertile (weight: 44.9 ± 9.3 vs. 51.4 ± 10.6, P < 0.01; WC: 59.9 ± 8 vs. 64 ± 7.9, P < 0.01; BMI: 18.6 ± 3.1 vs. 20.6 ± 3.5, P < 0.01). CONCLUSIONS: The current study findings suggest that the Iranian Central Obesity Making Dietary Pattern is directly associated with waist circumference (marker of central obesity), while lacto vegetarian dietary pattern is reversely associated with weight, waist circumference and BMI. Special obesity pattern in Iranian young females can be justified by Iranian Central Obesity Making Dietary Pattern".

Assessing study skills among university students: an Iranian survey.

PURPOSE: Numerous studies have revealed that study skills have a constructive role on the academic performance of students, in addition to educational quality, student' intelligence, and their affective characteristics. This study aims to examine study skills and the factors influencing them among the health sciences students of Urmia University of Medical Sciences in Iran. METHODS: This was a cross-sectional study carried out from May to November 2013. A total of 340 Urmia health sciences students were selected using a simple sampling method. Data were collected using the Study Skills Assessment Questionnaire of Counseling Center of Houston University and analyzed with descriptive and analytical statistics. RESULTS: The mean and standard deviation of the students' study skills were 172.5±23.2, out of a total score of 240. Around 1.2% of the study skills were weak; 86.8%, moderate; and 12%, good. Among the study skills, the scores of time management, and memory and concentration were better than the others. Also, there was a significant positive correlation between study skills scores and the students' family housing status and academic level (P<0.05). CONCLUSION: Although the majority of the participants had moderate study skills, these were not sufficient and far from good. Improving and promoting the study skills of university students require the designing and implementing of education programs for study strategies. Therefore, decision makers and planners in the educational areas of universities should consider the topic described above.

Factors Influencing Physical Activity Behavior among Iranian Women with Type 2 Diabetes Using the Extended Theory of Reasoned Action.

BACKGROUND: Findings of most studies indicate that the only way to control diabetes and prevent its debilitating effects is through the continuous performance of self-care behaviors. Physical activity is a non-pharmacological method of diabetes treatment and because of its positive effects on diabetic patients, it is being increasingly considered by researchers and practitioners. This study aimed at determining factors influencing physical activity among diabetic women in Iran, using the extended theory of reasoned action in Iran. METHODS: A sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran, participated in the study. Appropriate instruments were designed to measure the desired variables (knowledge of diabetes, personal beliefs, subjective norms, perceived self-efficacy, behavioral intention and physical activity behavior). The reliability and validity of the instruments were examined and approved. Statistical analyses of the study were conducted by inferential statistical techniques (independent t-test, correlations and regressions) using the SPSS package. RESULTS: The findings of this investigation indicated that among the constructs of the model, self efficacy was the strongest predictor of intentions among women with type 2 diabetes and both directly and indirectly affected physical activity. In addition to self efficacy, diabetic patients' physical activity also was influenced by other variables of the model and sociodemographic factors. CONCLUSION: Our findings suggest that the high ability of the theory of reasoned action extended by self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Educational interventions based on the proposed model are necessary for improving diabetics' physical activity behavior and controlling disease.
