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.

Background and aim Expenditure on adolescents' health promotion is critical to enhancing quality of life and fundamental for the prosperity of countries. This study tried to investigate the relationships between information-motivation-behavioral skills (IMB) model constructs as predictors of high school student's health-promoting lifestyle (HPL) in Southwest Iran. Methods This cross-sectional descriptive-analytic study was conducted on 400 students in Southwest Iran. Sample size required for this study was obtained using Soper's structural equation modeling (SEM) calculator. The stratified random sampling method was used in this study. A path analysis was taken to evaluate the HPL main determinants utilizing SEM. Results Information only had a significant indirect relationship with adolescents' HPL. But, both motivation and behavioral skills constructs had significant direct and indirect relationship with adolescents' HPL. The behavioral skill construct was the most imperative predictor variable. In general, behavioral skills construct (75%), motivation (66%) and knowledge (50%) constructs had the highest impact on HPL. The IMB model was able to explain 71% of the variance in adolescents' HPL. Conclusion The findings of the study showed that the IMB model was appropriate for explaining adolescents' HPL. It is necessary that actions are taken to improve behavioral skills and promote adolescents' HPL.

IntroductionAnticipating effective factors in information system acceptance by using persuasive messages, is one of the main issues less focused on so far. This is one of the first attempts at using the elaboration-likelihood model combined with the perception of emotional, cognitive, self-efficacy, informational and normative influence constructs, in order to investigate the determinants of intention to continue use of the hospital information system in Iran.MethodsThe present study is a cross-sectional survey conducted in 2014. 600 nursing staff were chosen from clinical sectors of public hospitals using purposive sampling. The questionnaire survey was in two parts: Part one was comprised of demographic data, and part two included 52 questions pertaining to the constructs of the model in the study. To analyze the data, structural equation model using LISREL 8.5 software was applied.ResultThe findings suggest that self-efficacy (t= 6.01, β= 0.21), affective response (t= 5.84, β= 0.23), and cognitive response (t= 4.97, β= 0.21) explained 64% of the variance for the intention of continuing to use the hospital information system. Furthermore, the final model was able to explain 0.46 for self-efficacy, 0.44 for normative social influence, 0.52 for affective response, 0.55 for informational social influence, and 0.53 for cognitive response.ConclusionDesigning the necessary mechanisms and effective use of appropriate strategies to improve emotional and cognitive understanding and self-efficacy of the nursing staff is required, in order to increase the intention of continued use of the hospital information system in Iran.

IntroductionWe aimed to assess quality of life related to oral health in narcotic or stimulant users those were referred to maintenance methadone therapy (MMT) centers in Ahvaz City, Iran.MethodsIt was a cross-sectional study based on exploratory approach which has conducted on 187 narcotic and stimulant users in Ahvaz city; during 15th May till September 2020. Data was selected by available non-random sampling method. The data collection tools included the demographic variables and the standard OHIP-14 questionnaires. All tests were used as descriptive statistics, Kolmogorov-Smirnov tests, independent t-test, one-way analysis of variance. P-values of less than 0.05 was considered significant.ResultsThe mean and standard deviation of the participants' age was 36.03 ± 8.98 years. The quality-of-life scores related to oral health were totally 34.89 ± 6.50 as well as 37.37 and 33.96 in narcotic and stimulant users, respectively. The total quality of life related to OHIP-14 did not have a significant relationship with variables of age, life companions, level of education, number of children, economic status, employment status, insurance status, underlying disease, toothbrush use status, last dentist visit, and number of missing teeth (P &gt; 0.05). However, a significant difference was found between the quality of life related to oral health based on the type of substance used (narcotic or stimulant), so that the mean quality of life related to oral health was higher in narcotic than stimulant users (P &lt; 0.05).ConclusionQuality of life related to OHIP-14 was more unfavorable in stimulant users than narcotic users. So, policy makers and authorities are required to focus their interventions and research programs to improve health-related quality of life in users, especially stimulant.
