Health literacy and mental health: a national cross-sectional inquiry.

Health literacy and mental health are among the most important issues in the modern health and era of public health. This study aimed to investigate the association between health literacy and mental health status. This was a national cross-sectional study that was conducted in Iran. A sample of literate individuals aged 18-65 was entered into the study using multistage sampling. The data were collected by the Health Literacy Instrument for Adults (HELIA) and the 12-item General Health Questionnaire (GHQ-12). Logistic regression and path analysis were used for data analysis. A total of 20,571 individuals completed the questionnaires. The mean(± SD) age of participants was 34.9(± 11.8) years old, 51% were female, and 38.1% had higher education. The mean(± SD) health literacy score was 68.3(± 15.2), and 29.8% of the respondents reported some mental health problems. Logistic regression analysis showed that limited health literacy was associated with poor mental health status (OR 2.560, 95% CI 2.396-2.735, P = 0.001). The path analysis showed that an increase in health literacy could reduce psychological and social dysfunction (the effect of health literacy on reducing psychological distress is more profound). It is recommended to carry out interventions that strengthen adult's cognitive and communication skills to improve their ability to access and use health information to make healthy choices.

Exposure to the COVID-19 news on social media and consequent psychological distress and potential behavioral change.

Exposure to coronavirus disease 2019 (COVID-19) news pandemic is inevitable. This study aimed to explore the association between exposure to COVID-19 news on social media and feeling of anxiety, fear, and potential opportunities for behavioral change among Iranians. A telephone-based survey was carried out in 2020. Adults aged 18 years and above were randomly selected. A self-designed questionnaire was administered to collect information on demographic variables and questions to address exposure to news and psychological and behavioral responses regarding COVID-19. A multivariate logistic regression analysis was performed to assess the relationship between anxiety, fear, behavioral responses, and independent variables, including exposure to news. In all, 1563 adults participated in the study. The mean age of respondents was 39.17 ± 13.5 years. Almost 55% of participants reported moderate to high-level anxiety, while fear of being affected by COVID-19 was reported 54.1%. Overall 88% reported that they had changed their behaviors to some extent. Exposure to the COVID-19 news on social media was the most influencing variable on anxiety (OR 2.21, 95% CI 1.62-3.04; P < 0.0001), fear (OR 1.95, 95% CI 1.49-2.56; P < 0.0001), and change in health behaviors (OR 2.02, 95% CI 1.28-3.19; P = 0.003) in the regression model. The fear of being infected by the COVID19 was associated with the female gender and some socioeconomic characteristics. Although exposure to the COVID-19 news on social media seemed to be associated with excess anxiety and fear, it also, to some extent, had positively changed people's health behaviors towards preventive measures.

Development and psychometric properties of the HBM-based substance abuse prevention questionnaire (HBM-SAPQA) among Afghanian students.

In Afghanistan, adolescents and young people are the most important at risk groups for substance abuse. Considering the importance of model-based interventions in this group, this study aims to design and validate a questionnaire based on the Health Belief Model (HBM) for assessing the beliefs of Afghan students regarding substance abuse prevention behavior. This study was conducted in two stages. In the first stage, the items of the questionnaire were designed by conducting a combined documentary literature review and qualitative study. In the next step, its psychometric properties were evaluated through qualitative and quantitative face and content validity (CVR & CVR) and structural validity (exploratory factor analysis). Finally, internal consisitency through Cronbach's alpha as well as reliability was assessed. To above steps, the SPSS version 18 was applied. 57 items were obtained for the questionnaire by performing a qualitative study and using existing scientific sources for literature review. In checking the face validity of the questionnaire items quantitatively (calculating the impact score), the impact score of all items was above 1.5. The CVR of each item was more than 0.8 and their CVI was more than 0.79. In EFA (using the information of 408 students with average age of 23 years old), the final model was confirmed with 38 related to the main HBM constructs in 5 factors, which covered about 40% of the variance. Acceptable values of Cronbach's alpha between 0.71 and 0.81 for all factors confirmed the reliability of the questionnaire. The HBM-SAPQA obtained the acceptable validity/reliability to apply the beliefs of Afghan students regarding substance abuse preventive behavior.

An internet-based educational intervention for mothers targeting preschoolers' weight management promotion (PWMP): a pilot study.

BACKGROUND: The prevalence of overweight and obesity among children has raised public health concerns. This study aimed to design and evaluate a behaviour change intervention program to promote weight management among Tehranian preschoolers. METHODS: The PRECEDE-PROCEED model is one of the most popular models in health education used to develop and evaluate most educational interventions. In this one-group pre and post-pilot study, 13 mothers of preschoolers were recruited from preschools in Tehran (the capital of Iran), in August 2020. Mothers received a six-week educational intervention, including text messages and educational videos via WhatsApp, to increase their self-efficacy to overcome barriers changing their children's lifestyle. Mothers reported preschoolers' height and weight to assess Body Mass Index and filled out the Food Frequency Questionnaire, the Persian version of the children's health-related quality of life questionnaire, and demographic features. The "Children's physical activity and sedentary behaviors checklist," newly designed by the researchers, was also filled out by mothers. These behaviors were measured according to the minutes that children were involved in these activities in a day, and the days they spent in a week for them. All variables were measured at baseline, immediately after the intervention and three months later. Data analysis was performed using SPSS IBM statistics version 22. Friedman test was used to evaluate changes over time. RESULTS: The findings demonstrated that the mean BMI z-score stayed steady between baseline, immediately after the intervention and after three months (P = 0.60). Besides, after three months, the intervention programme led to a decrease in soft drink consumption (P = 0.001), and an increase in parental perception of their child's general health (P = 0.05), the parental concern regarding their child's emotional and physical health (P = 0.002) and minutes of physical activity per day (P = 0.02). However, fruit intake decreased (P = 0.01), and simple sugar, such as cube, increased (P = 0.03). CONCLUSION: Results from this study are promising but should be interpreted with caution and should be replicated on a larger scale and compared with a control group to evaluate whether effects are maintained in a larger sample.

Measuring health literacy: A systematic review and bibliometric analysis of instruments from 1993 to 2021.

BACKGROUND: It has been about 30 years since the first health literacy instrument was developed. This study aimed to review all existing instruments to summarize the current knowledge on the development of existing measurement instruments and their possible translation and validation in other languages different from the original languages. METHODS: The review was conducted using PubMed, Web of Science, Scopus, and Google Scholar on all published papers on health literacy instrument development and psychometric properties in English biomedical journals from 1993 to the end of 2021. RESULTS: The findings were summarized and synthesized on several headings, including general instruments, condition specific health literacy instruments (disease & content), population- specific instruments, and electronic health. Overall, 4848 citations were retrieved. After removing duplicates (n = 2336) and non-related papers (n = 2175), 361 studies (162 papers introducing an instrument and 199 papers reporting translation and psychometric properties of an original instrument) were selected for the final review. The original instruments included 39 general health literacy instruments, 90 condition specific (disease or content) health literacy instruments, 22 population- specific instruments, and 11 electronic health literacy instruments. Almost all papers reported reliability and validity, and the findings indicated that most existing health literacy instruments benefit from some relatively good psychometric properties. CONCLUSION: This review highlighted that there were more than enough instruments for measuring health literacy. In addition, we found that a number of instruments did not report psychometric properties sufficiently. However, evidence suggest that well developed instruments and those reported adequate measures of validation could be helpful if appropriately selected based on objectives of a given study. Perhaps an authorized institution such as World Health Organization should take responsibility and provide a clear guideline for measuring health literacy as appropriate.

Exploring the facilitators and barriers to high-risk behaviors among school transportation drivers: a qualitative study.

BACKGROUND: School transportation (ST) crashes are associated with serious adverse consequences, particularly for students in developing countries. High-risk behaviors (HRBs) of ST drivers are a major factor contributing to ST crashes. This study aimed at exploring the facilitators and barriers to HRBs among ST drivers. METHODS: This qualitative study was conducted in 2019-2020. Participants were ST drivers, students, parents, and school staff purposively selected from Tehran, Iran. Data were collected through in-depth semi-structured interviews and focus group discussions and were concurrently analyzed through conventional content analysis. FINDINGS: Participants were fifteen ST drivers with a mean age of 45 ± 10.2 years and 24 students, parents, and school staff with a mean age of 28.62 ± 16.08 years. The facilitators and barriers to HRBs came into five main categories, namely previous experiences of HRBs, perceived gains and risks of HRBs, motivating and inhibiting feelings and emotions, positive and negative subjective norms, and perceived mastery in driving. CONCLUSION: A wide range of facilitators and barriers can affect HRBs among ST drivers. Strategies for preventing HRBs among ST drivers should be multidimensional and individualized and should focus on strengthening the barriers and removing the facilitators to HRBs.

The relationship between happiness and self-rated health: A population-based study of 19499 Iranian adults.

BACKGROUND: Health is one of the most important factors that affect happiness. This study aimed to assess the association between happiness and self-rated health among the Iranian adult population. METHODS: This cross-sectional study was conducted on a sample of adults aged 18-65 In Iran in 2020. Demographic information, the Oxford Happiness Questionnaire, and a single item on self-rated health were used to collect the data. The relationship between happiness with demographic variables and self-rated health was examined by performing logistic regression analyses. RESULTS: In all, 19499 were studied (9845 males and 9654 females). The mean age of participants was 36.38± 8.17 years. The mean happiness score was 4.1± 0.57 (out of 6) and this for self-rated health was 3.66±1.2 (out of 5). The results obtained from logistic regression analysis showed that very poor health status (OR: 5.114, 95% CI, P = 4.490-5.824, p <0.001), poor or very poor income status (OR: 1.553, 95% CI, P = 1.406-1.716, p <0.001), unemployment (OR: 1.704, 95% CI, P = 1.432-2.029, p <0.001), being aged 25-34 years (OR: 1.190, 95% CI, P = 1.088-1.302, p <0.001), and years of education (OR for 10-12 years of education: 1.271, 95% CI = 1.174-1.377, p< 0.001) were significant contributing factors to a lower happiness. CONCLUSION: The results showed that self-rated health was the most significant factor that affected happiness even after adjustment for socioeconomic variables, including age, income, employment, and education. Indeed, improving population health might be an effective measure to improve happiness among Iranians.

Explaining the concept of maternal health information verification and assessment during pregnancy: a qualitative study.

BACKGROUND: Pregnant women use information sources for their own health and health of their children. However, despite the importance of trusting the information sources, pregnant women may not have the ability to verify the maternal health information, which could have negative consequences for their health. The purpose of this study was to explain the concept of maternal health information verification and assessment in pregnant women according to their experiences and perception. METHODS: This is a qualitative study that was conducted in 2017 in Tehran, Iran. The participants in this study consisted of 19 pregnant women who were selected by purposeful sampling. To collect data, semi-structured, in-depth and face to face interviews were conducted with participants and continued until saturation of data. Conventional content analysis method was used to analyze the data and to identify concepts and synthesize them into general classes. MAXQDA software version 10 was used to manage the data. RESULTS: In the process of data analysis, the concept of verification and assessment of maternal health information in pregnancy was explained in two main categories, including "Validity of information resources" and "Reliance on information resources." The category of Validity of information resources had two subcategories of valid and invalid sources, and the main category of Reliance on information resources had two subcategories of indicators of assurance, and confusion and trying to obtain assurance. CONCLUSION: The results indicated that pregnant women used various sources and indicators, as well as different evaluation methods to obtain information and verify it, especially when they are confused. Thus, health authorities and healthcare professionals should provide appropriate programs to familiarize mothers with credible sources, train pregnant women on standards and practices for judging the accuracy of information, and create a safe margin of information.

A mobile-based educational intervention on STI-related preventive behavior among Iranian women.

While rates of sexually transmitted infections (STIs) in Iran are alarming, little is known about preventive sexual behaviors. The purpose of this article was to assess the effect of a mobile-based educational program to promote preventive behaviors regarding STIs in Iranian women. Using Roger's protection motivation theory, the following measures were developed as the study's conceptual framework: STI knowledge, STI vulnerability, STI prevention self-efficacy and STI prevention intentions. These variables were measured by the Persian version of a valid Korean four-scale tool. Data from 76 women were analyzed: 37 women in the smartphone application (Experimental) group and 39 in the control group. Health Education Sexually Transmitted Infections Application was developed as a smartphone application training program. Participants were tested at three-time points: pre-test (baseline), post-test 1 (immediately after the program's completion) and post-test 2 (16 weeks after the program's completion). Significant group differences were found at different times in STI knowledge, vulnerability, prevention self-efficacy and prevention intentions. The smartphone application was effective in sustaining the effects of the educational program in the experimental group. The development of appropriate teaching materials on sensitive public health issues, such as STIs to promote individual self-learning skills is suggested.

Development and psychometric properties of maternal health literacy inventory in pregnancy.

BACKGROUND: Pregnancy is one of the most sensitive and important stages of women's life. Maternal health literacy is the key to achieving a healthy pregnancy. It also affects pregnancy outcomes by improving the quality of health care in this period. The aim of this study was to develop and evaluate the psychometric properties of maternal health literacy inventory in pregnancy (MHELIP). METHODS: This sequential, exploratory and mixed study was carried out in two parts (qualitative study and psychometric evaluation of the tool) in Tehran in 2016-18. The first part involved a qualitative content analysis with a traditional approach using in-depth, semi-structured and personal interviews with 19 eligible pregnant women. Then, the pool of items extracted from the qualitative part was completed by reviewing the existing literature and tools. In the second part, the overlapping items were summarized and the tool was validated. In order to evaluate the construct validity, a cross-sectional study was conducted with the participation of 320 pregnant women. Data analysis was performed by SPSS-19 software using exploratory factor analysis and reliability tests (Cronbach's alpha and ICC). RESULTS: Findings of qualitative part produced a pool of 120 items that reached to 124 items after reviewing the literature. After confirming face and content validity by calculating CVI and CVR for each item, 53 items remained in the pool. Finally, the results of exploratory factor analysis confirmed a tool with 48 items in four factors, explaining 46.49% of the variance of total variables of the tool. Reliability of the tool was approved by Cronbach's alpha = 0.94 and test-retest with 2-weeks intervals, indicating an appropriate stability for the scale (ICC = 0.96). Finally, the tool was finalized with 48 items in 4 dimensions, including "Maternal Health Knowledge", "Maternal Health Information Search", "Maternal Health Information Assessment" and "Maternal Health Decision Making and Behavior". CONCLUSION: The designed tool is a multidimensional, reliable and validated scale for assessing maternal health literacy during pregnancy. This tool can be used to evaluate different aspects of maternal health literacy in pregnant women, which was prepared based on their experiences during a qualitative study.

Development and validation of a short and easy-to-use instrument for measuring health literacy: the Health Literacy Instrument for Adults (HELIA).

BACKGROUND: Health literacy is the ability to access to, understand, evaluate and use of essential health information to make basic health decisions. This study aimed to develop and psychometrically evaluate an instrument for measuring health literacy among adults (the Health Literacy Instrument for Adults - HELIA). METHODS: In addition to a literature review, a panel of specialists from different disciplines was formed to generate an item pool. Then, a framework was defined to develop the initial questionnaire based on a definition of health literacy and the most important global public health issues. The initial questionnaire contained 66 items. Next, 15 experts in public health were approached to assess content validity. Consequently, 19 items were removed and a provisional version of the questionnaire with 47 items was provided. Finally, a random sample of adults completed the questionnaire and psychometric properties of the instrument were assessed. RESULTS: Overall, 323 adults aged 18 to 65 years old completed the questionnaire. When the exploratory factor analysis was performed, 33 items were loaded, which indicated a 5-factor solution for the questionnaire that jointly explained 52.9% of the variance observed. The factors were as follows: access to information (6 items), reading (4 items), understanding (7 items), appraisal (4 items), and decision making/behavioral intention (12 items). Confirmatory factory analysis also indicated a good fit to the data for the five-latent structure (χ2/df = 1.60, SRMR = 0.049; RMSEA = 0.043; CFI = 0.98; NFI = 0.95; NNFI = 0.98 and GFI = 0.87). Additional analysis for internal consistency showed satisfactory results with Cronbach's alpha coefficients ranging from 0.72 to 0.89. Intraclass correlation coefficient (test-retest analysis) also showed acceptable stability for the questionnaire (ICC = 0.84). The mean score for health literacy as measured by the HELIA was 76.3 (SD = 15.1) out of 100 for the study sample. CONCLUSION: The findings suggest that the Health Literacy Instrument for Adults (HELIA) is a valid and reliable instrument for measuring health literacy. It is a short and easy-to-use instrument that could be applied in different settings.

A mobile-based educational intervention on sexo-marital life in Iranian men with spinal cord injury: a randomized controlled trial.

STUDY DESIGN: A randomized controlled trial. OBJECTIVE: To assess the effectiveness of a mobile-based educational intervention on sexo-marital life in Iranian men with spinal cord injury (SCI). SETTING: Foundation of Martyrs and Veterans Affairs', "Spinal Cord Injury Association", and the "Protection Center of Spinal Cord Disables". METHODS: Participants were men with SCI aged at least 18 years old. The effectiveness of a mobile App was evaluated on 70 married men with SCI. Sexual adjustment, sexual satisfaction, marital adjustment, and marital satisfaction were assessed by valid and reliable questionnaires at baseline, 4 and 8 weeks after the intervention. RESULTS: The between-group mean difference (95% CI) of sexual adjustment (4.2, CI: 3.6-4.8) after 4 weeks as well as 8 weeks (8.6, CI: 7.6-9.5) after baseline was significant (P < 0.001). The between-group mean difference (95% CI) of sexual satisfaction (6.9, CI: 8-11.2) after 4 weeks as well as 8 weeks (16.4, CI: 14.1-18.7) after baseline was significant (P < 0.001). There were significant increases in all the domains of marital satisfaction's between-group mean differences after 4 weeks as well as 8 weeks after baseline (P < 0.001). Repeated measures ANOVA showed there was no statistically significant increase in marital adjustment's between-group mean difference (95% CI) after 4 weeks (-0.1, CI: -0.1- 0, P < 0.16) as well as 8 weeks (0.4, CI: -0.3-1.1, P < 0.25) after baseline. CONCLUSION: The application-based educational intervention showed the positive effect of education on sexo-marital life in men with SCI. We recommend the rehabilitation team's healthcare providers embrace this educational strategy for individuals with SCI.

Evaluating the impact of HBM-based education on exercise among health care workers: the usage of mobile applications in Iran.

BACKGROUND: Mechanical life made us witness the growing increase of chronic diseases despite the prominent scientific developments in the field of health, treatment and control. The aim of this study was to evaluate the impact of educational intervention based on Health Belief Model (HBM) using mobile applications (Telegram messenger) on doing exercise among the health care workers of Ilam university of medical sciences in 2017. METHODS: In this interventional study, 114 people working in Ilam University of medical sciences participated in two groups of intervention and control (employed at two different cities) after providing the informed consent form. HBM-ISCS questionnaire was used to collect the required data and its reliability was approved using Cronbach's alpha. Descriptive statistics, chi square, t test, repeated measures ANOVA (RMANOVA) and structural equation model (SEM) were used. RESULTS: Half of the participants were men, 58.77% of them were undergraduate. The mean and SD of their age was 37.61 ± 4.88 years. Based on the results of the repeated measures analysis of variance test (before and after the intervention) in the intervention group, there were significant difference in all of the HBM constructs (perceived barriers was excepted), daily and weekly exercises, blood biochemical markers of the participants (P > 0.05). The above changes were not significant in the control group (P ≥ 0.05). CONCLUSION: Exercise is closely related to the beliefs of people, so implementing educational interventions based on Telegram messenger with emphasis on health beliefs and using HBM can lead to have exercise. Therefore, this application can be a suitable tool to deliver trainings, especially when holding in-person classes is difficult.

Risk factors associated with self-medication among women in Iran.

BACKGROUND: Self-medication is a public health concern that may create several problems such as increase in drug resistance, raise in drug use per capita, and creating side effects. This study was conducted to determine predictors of self-medication based on the theory of planned behavior (TPB) among the Iranian women. METHODS: This was a cross sectional study. A sample of married women completed a validated, anonymous, self-administered questionnaire. The questionnaire included items on demographic variables, knowledge, and TPB structures, and the checklist of women's self-medication practices. The study was conducted in six urban health centers of Shush and Zarandieh in Iran during January to July 2016. Data were analyzed using SPSS 23.0 applying t-test and logistic regression. RESULTS: A total of 360 women took part in the study. The results showed that 76% of women had a history of self-medication and 98.9% stored drugs at home. The most important reasons for self-medication were perceived self-medication harmless (41%), having history of a disease (35.5%), and availability of medications at home (34%). The most frequent diseases for self-medication were fatigue, weakness, and anxiety (24%), and fever (20%). The results obtained form logistic regression analysis indicated that age, place of residence, education level, health insurance status, as well as all constructs of the TPB were significant predictors for self-medication. CONCLUSION: The findings indicated that the prevalence of self-medication among Iranian women was high. Since women have important role in shaping the family health, the issue of high prevalence among this population should be considered as a serious problem in Iran. In this regard, it is recommended to consider factors affecting self-medication among women to reduce this health threatening factors.

Evaluation of Mackey Childbirth Satisfaction Rating Scale in Iran: What Are the Psychometric Properties?

BACKGROUND: With the integration of the evaluation of patient satisfaction in the overall assessment of healthcare services, authorities can be assured about the alignment of these services with patient needs and the suitability of care provided at the local level. OBJECTIVES: This study was conducted in 2013 in Zahedan, Iran, in order to assess the psychometric properties of the Iranian version of the mackey childbirth satisfaction rating scale (MCSRS). PATIENTS AND METHODS: For this study, a methodological design was used. After translating the MCSRS and confirming its initial validity, the questionnaires were distributed among women with uncomplicated pregnancies and no prior history of cesarean section. The participants had given birth to healthy, full-term, singletons (with cephalic presentation) via normal vaginal delivery at hospitals within the past six months. Cronbach's alpha and test-retest (via the intraclass correlation coefficient) were applied to analyze the internal consistency and reliability of the scale. Moreover, the validity of the scale was tested via exploratory factor analysis, confirmatory factor analysis, and convergent validity. RESULTS: The MCSRS consists of six subscales. Through the process of validation, two partner-related items ("partner" subscale) of the scale were excluded due to cultural barriers and hospital policies. Cronbach's alpha for the total scale was 0.78. It ranged between 0.70 and 0.86 for five subscales, and was 0.31 for the "baby" subscale. Factor analysis confirmed the subscales of "nurse," "physician," and "baby," which were identified in the original scale. However, in the translated version, the "self" subscale was divided into two separate dimensions. The six subscales explained 70.37% of the variance. Confirmatory factor analysis indicated a good fitness for the new model. Convergent validity showed a significant correlation between the MCSRS and the SERVQUAL scale (r = 0.72, P < 0.001). Moreover, the Farsi version of the MCSRS showed excellent repeatability (r = 0.81 - 0.96 for individual subscales and r = 0.96 for the entire scale). CONCLUSIONS: The study findings indicated the Farsi version of the MCSRS is a reliable and valid instrument. However, according to the reliability assessment and factor analysis, the "baby" and "self" subscales need further revisions.

Iranian Health Literacy Questionnaire (IHLQ): An Instrument for Measuring Health Literacy in Iran.

BACKGROUND: Promoting Health Literacy (HL) is considered as an important goal in strategic plans of many countries. In spite of the necessity for access to valid, reliable and native HL instruments, the number of such instruments in the Persian language is scarce. Moreover, there is no good estimation of HL status in Iran. OBJECTIVES: The aim of this study was to provide a valid, reliable and native instrument to measure and monitor community HL in Iran and also, to provide an estimation of HL status in two Iranian provinces. PATIENTS AND METHODS: By applying the multistage cluster sampling, 1080 respondents (540 from each gender) were recruited from Kerman and Mazandaran provinces of Iran, from February to June 2014 to participate in this cross-sectional study. The development of the Iranian Health Literacy Questionnaire (IHLQ) was initiated with a comprehensive review of the literature. Then, face, content and construct validity as well as reliability were determined. RESULTS: Internal consistency and test-retest reliability (ICC) of the factors was in the range of 0.71 to 0.96 and 0.73 to 0.86, respectively. In order to construct validity, Exploratory Factor Analysis (EFA) Kaiser-Meyer-Olkin (KMO) = 0.95 and Bartlett's test result of 3.017 with P < 0.001) with varimax rotation was used. Optimal reduced solution, including 36 items and seven factors, was found in EFA. Five of the factors identified were reading/comprehension skills, individual empowerment, communication/decision-making skills, social empowerment and health knowledge. CONCLUSIONS: It was concluded that IHLQ might be a practical and useful tool for investigating HL for Persian language speakers around the world. Since HL is dynamic and its instruments should be regularly revised, further studies are recommended to assess HL with application of IHLQ to detect its potential imperfections.

Psychometric analysis of the ambulatory care learning education environment measure (ACLEEM) in Iran.

BACKGROUND: Examining educational environment (academic and clinical) by means of a valid, reliable and comprehensive questionnaire is a major key in achieving a highly qualified student - oriented curricula. The Persian translation of Ambulatory Care Learning Education Environment Measure-ACLEEM questionnaire has been developed to support this goal, and its psychometrics has been explored in this administration in teaching hospitals affiliated to Tehran University of Medical Sciences. METHODS: This descriptive - analytical study involved medical residents in four major clinics. In this study, the ACLEEM Questionnaire was conducted after translating and retranslating the questionnaire and examine the face and content validity, construct validity, test retest reliability and internal consistency coefficient. RESULTS: In this study, 157 out of 192 residents completed the questionnaire (response rate 82%). The mean age of the residents was 31.81 years .The final mean of the questionnaire was calculated as 110.91 out of 200 (with 95% confidence interval). Test - retest stability of the questionnaire was between 0.322 and 0.968. The face validity of the questionnaire was confirmed. The content validity ratio was 0.64; and content validity Index was 0.78. In Exploratory factor analysis, eight factors were confirmatory that changed the orientation of some questions. The Cronbach's alpha coefficient of the whole questionnaire was 0.936. CONCLUSION: According to the data, the Persian version of the ACLEEM questionnaire has sufficient psychometric reliability and validity to be used for conducting research, teaching and practicing the educational learning environment in ambulatory care in Iran.

Substance use avoidance among Iranian male adolescents: a comparison of three versions of the theory of reasoned action.

The theory of reasoned action (TRA) is one of the most common models in predicting health-related behaviors and is used more often in health education studies. This study aimed to add two control constructs (perceived behavioral control - PBC and self-efficacy - SE) to the TRA and compare them using the structural equation modeling (SEM) for substance use avoidance among Iranian male adolescents in order to find out which model was a better fit in predicting the intention. This was a cross-sectional study carried out in Tehran, Iran. Data were collected from a random sample of high school male students (15-19 years of age) using a questionnaire containing items related to the TRA plus items reflecting two additional constructs (SE and PBC). In all, 433 students completed the questionnaires. The results obtained from SEM indicated a better fit to the data for the TRA with SE compared to the TPB (TRA with PBC) and TRA (χ2/df=2.55, RMSEA=0.072, CFI=0.96, NFI=0.94, NNFI=0.95, SRMR=0.058). Comparing SE and PBC, the results showed that self-efficacy was a better control construct in improving the TRA and predicting substance use avoidance intention (41%). The TRA with SE had a better model fit than TPB and the original version of the TRA.

The School Anxiety Scale-Teacher Report (SAS-TR): translation and psychometric properties of the Iranian version.

BACKGROUND: The School Anxiety Scale-Teacher Report (SAS-TR) was designed to assess anxiety in children at school. The SAS-TR is a proxy rated measure and could assess social anxiety, generalized anxiety and also gives a total anxiety score. This study aimed to translate and validate the SAS-TR in Iran. METHODS: The translation and cultural adaptation of the original questionnaire were carried out in accordance with the published guidelines. A sample of students participated in the study. Reliability was estimated using internal consistency and test-retest analysis. Validity was assessed using content validity. The factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses. RESULTS: In all 200 elementary students aged 6 to 10 years were studied. Considering the recommended cut-off values, overall the prevalence of high anxiety condition in elementary students was found to be 21 %. Cronbach's alpha coefficient for the Iranian SAS-TR was 0.92 and intraclass correlation coefficient (ICC) was found to be 0.81. The principal component analysis indicated a two-factor structure for the questionnaire (generalized and social anxiety) that jointly accounted for 55.3 % of variances observed. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure of the questionnaire. CONCLUSION: In general the findings suggest that the Iranian version of SAS-TR has satisfactory reliability, and validity for measuring anxiety in 6 to 10 years old children in Iran. It is simple and easy to use and now can be applied in future studies.

The 12-item medical outcomes study short form health survey version 2.0 (SF-12v2): a population-based validation study from Tehran, Iran.

BACKGROUND: The SF-12v2 is the improved version of the SF-12v1. This study aimed to validate the SF-12v2 in Iran. METHODS: A random sample of the general population aged 18 years and over living in Tehran, Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses (EFA and CFA). RESULTS: In all, 3685 individuals were studied (1887 male and 1798 female). Internal consistency for both summary measures was satisfactory. Cronbach's α for the Physical Component Summary (PCS-12) was 0.87 and for the Mental Component Summary (MCS-12) it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status (P < 0.05). Furthermore, as hypothesized the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12, while the vitality, social functioning, role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 59.9% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). CONCLUSION: Although the findings could not be generalized to the Iranian population, overall the findings suggest that the SF-12v2 is a reliable and valid measure of health related quality of life among Iranians and now could be used in future health outcome studies. However, further studies are recommended to establish its stability, responsiveness to change, and concurrent validity for this health survey in Iran.
