Predicting the significant determinants of health-related quality of life through the application of structural equation modeling in adolescents has received little attention in the health education and health promotion literature. The purpose of this study was to investigate the relationships between self-efficacy, barriers, social support, health-promoting lifestyle, and health-related quality of life among Iranian adolescent girls. Pender's health promotion model guided this study. This was a cross-sectional survey of 500 students who were recruited in Kashan, Iran. Their health-related quality of life was measured by using the Short Form Health Survey. A path analysis was conducted to predict the health-related quality of life determinants. The results indicated that 71% of the variance in health-related quality of life could be predicted by the variables. The results affirmed that self-efficacy was the most significant predictor of the students' health-related quality of life. It was concluded that interventions that are aimed at improving self-efficacy can lead to the enhancement of health-related quality of life among adolescent girls in the developing country of Iran.

BackgroundThe present study was conducted to determine the impact of educational intervention based on adult learning theory on oral health related quality of life of the elderly.Materials and methodsThis study (IRCT20120910010804N13) was performed with 92 elderly patients referred to the dental clinic of Ahvaz Jundishapur University of medical sciences. Participants were randomly divided into experimental and control groups. The data were gathered by a questionnaire with demographic variables, variables of oral health related quality of the elderly, and variables for assessing the effectiveness of adult learning theory. Following pre-test, educational programs were conducted for the interventional group. After 1 month, the questionnaire was again administered to both groups. Next, the results of pre-test and post-test were analyzed using SPSS-23 at a significance level of 0.05.ResultsEducational intervention was significant in terms of overall oral health related quality of life and the overall effectiveness score of adult learning theory (P < 0.001). There was a significant difference between the two groups in terms of the mean change score of three physical, psychosocial, and pain dimensions following the educational intervention (P < 0.001).ConclusionEducation based on adult learning theory is recommended for improving oral health related quality of life among the elderly.Trial registrationIranian Registry of Clinical Trials, IRCT20120910010804N13.

Background Due to the need for informatics competencies in the field of nursing, the present study was conducted to design a psychometric instrument to determine the qualification of informatics competencies of employed nurses in educational care centers. Methods The questionnaire was made by reviewing existing scientific resources and assessment tools. Two hundred nurses were selected using simple random sampling. Structural equation modeling was used using the measurement model technique and the average variance was calculated. Linear structural relations (LISREL) software was used to test the assumptions and correlations of the model. Results Findings showed relatively good estimation in the fit of first-order measurement model. The informatics knowledge subscale with a determining rate of 0.90 had the greatest explanatory effect among the subscales and informatics skill with a determining rate of 0.67 and basic computer skill with a determining rate of 0.60 were observed. The second-order measurement model of fitness indicators showed that the three factors can well explain the multidimensional construct of informatics competency. Conclusions The designed tool can be used to develop educational strategies in relation to nursing students in the field of informatics and prepare them in the rich environment of information technology, which can be helpful in training nursing instructors.

ObjectivesPhysical activity behavior begins to decline during adolescence and continues to decrease throughout young adulthood. This study aims to explain factors that influence physical activity behavior in a sample of female adolescents using a health promotion model framework.MethodsThis cross-sectional survey was used to explore physical activity behavior among a sample of female adolescents. Participants completed measures of physical activity, perceived self-efficacy, self-esteem, social support, perceived barriers, and perceived affect. Interactions among the variables were examined using path analysis within a covariance modeling framework.ResultsThe final model accounted for an R2 value of 0.52 for physical activity and offered a good model-data fit. The results indicated that physical activity was predicted by self-esteem (β=0.46, p<0.001), perceived self-efficacy (β=0.40, p<0.001), social support (β=0.24, p<0.001), perceived barriers (β=-0.19, p<0.001), and perceived affect (β=0.17, p<0.001).ConclusionsThe findings of this study showed that the health promotion model was useful to predict physical activity behavior among the Iranian female adolescents. Information related to the predictors of physical activity behavior will help researchers plan more tailored culturally relevant health promotion interventions for this population.

Aims High blood pressure as a silent killer can endanger the health of the aged people. The purpose of this study was to assess the effect of motivational interviewing based on the health belief model on hypertension, self-care, and quality of life of rural aged people. Materials and Methods This semi-experimental study without a control group, was carried out on 120 rural aged people over 60 years of age, who were covered by city health centers of Ramhormoz in 2017. The subjects were selected through the multistage random sampling method. The aged people participated in the motivational interviewing classes for 1 month each week, 2 sessions in 30-45 minutes. Data were collected using social support, perceived barriers, self-efficacy, self-care, and quality of life questionnaires, before and after the educational intervention. The data were analyzed using the Wilcoxon signed-rank test, Pearson and Filon's z test and path analysis through LISREL 8.5 and SPSS 22 software. Findings After the educational intervention, the mean of systolic, diastolic blood pressure, and the average scores of social support, perceived barriers, self-efficacy, self-care and quality of life was improved significantly (p<0.001). Also, after the educational intervention, the variance of self-care and quality of life increased from %13 and %8 to %40 and %31, respectively. Conclusion Motivational interviewing has led to a better explanation of the health belief model in self-care and the quality of life by modifying the mental beliefs of aged people.
