Background: Food insecurity has a considerable impact on the social, physical, and psychological well-being of people and there is no food security assessment tool specific for Iranians. This study aimed to develop and assess the validity and reliability of an Iranian-specific food security questionnaire. Methods: The food security questionnaire was developed by five food security specialists by evaluating all available questionnaires (not specific to Iranians) in terms of applicability to Iranians. Furthermore, questions were developed from interviews conducted with ten families who were below the poverty threshold to understand how they described their food status. This questionnaire was administered to 200 households from different parts of Isfahan, Iran. Households were selected by multi-stage cluster randomized sampling. Households were categorized into 4 groups based on their score on the questionnaire; food secure (total score 0), mildly (total score 1-2), moderately (total score 3-7) and severely food insecure (total score 8-18). In the second stage of the study, 25 households were selected from each food security status group to evaluate the reliability and validity of the questionnaire by assessing sociodemographic, anthropometric, nutritional and biochemical parameters. Results: The prevalence of food security and mildly, moderately and severely food insecure were 24%, 33%, 27% and 16%, respectively. Content and face validity of the questionnaire was evaluated by experts, and latent class analysis confirmed construct validity. The developed questionnaire had good internal consistency (Cronbach's α = 0.91) and showed significant differences in hypothesized directions in food security status for sociodemographic factors. The prevalence of mothers, but not fathers or children, who had hemoglobin, mean corpuscular volume (MCV) and hematocrit less than the normal ranges increased (P = 0.04, P = 0.02, P = 0.02; respectively) with food insecurity. Conclusion: Our findings indicated that the developed questionnaire was a valid and reliable instrument to measure household food insecurity of Iranian families. [ABSTRACT FROM AUTHOR]

Background: Lack of accurate menstrual knowledge, attitude, and practices leave female adolescents ignorant of the necessary health behaviors during menstruation. This study aimed to develop a menstrual health-seeking behavior questionnaire based on the theory of planned behavior to evaluate its psychometric properties in female adolescents in Tehran. Methods: This study was conducted on 578 female adolescents aged 12-15 years in Tehran. The first draft of the menstrual health-seeking behavior questionnaire containing 52 items was developed based on the theory of planned behavior (TPB). The content and face validity of the questionnaire was assessed by a panel of experts. Construct validity was also assessed using exploratory factor analysis (KMO=0.73) with varimax rotation. Cranach's alpha and test-retest were used to examine the reliability of the questionnaire. All statistical analysis was performed using SPSS 23.0 and AMOS 23.0. Results: The content and face validity of the 42 items were finally confirmed. Content validity index was greater than 0.73 for all six TPB constructs. Explanatory factor analysis yielded an acceptable fit for the six-factor model (RMSE=0.053, 95% CI 0.042-0.064). These factors jointly explained 65% of the variance in the outcome variables. Cranach's alpha coefficients ranged from 0.79 to 0.91, demonstrating an excellent internal consistency and high reliability of the questionnaire. Test-retest reliability was also satisfactory for all items (ICC=0.86-0.94). Conclusion: The results illustrate that the menstrual health-seeking behavior questionnaire is psychometrically adequate and highly reliable. This theoretically grounded questionnaire can be well applied in future interventions for female adolescents to assess their menstrual health-related knowledge, attitude, and practices.

Aim: To develop a nutritional screening tool and examine its reliability and validity in elementary school children with malnutrition based on PRECEDE--PROCEED model, in Shiraz, Iran. Methods: A questionnaire was designed and its reproducibility was analysed via test--retest design among students with malnutrition. The students were in the fourth to sixth grades. Validity was assessed using face validity, content validity, construct validity, item difficulty and item discrimination. Reliability was measured by Cronbach's alpha (internal consistency), the intra-class correlation coefficient (ICC) and κ statistics (test--retest reliability). Results: A total of 165 primary school students (mean age of 11.21 ± 1.08 years, 65.5% females) participated in the study. The PRECEDE--PROCEED theoretical model for health education was adapted for this questionnaire. The questionnaire was divided into four main sections: predisposing, reinforcing, enabling factors and behaviour. Coefficient κ reliability estimate was above 0.9 for most scales. The ICCs for different scales of the questionnaire were within the range of 0.402-0.800. Values for κ ranged from 0.412 to 0.785 for most scales. Conclusions: The results showed reasonable validity, excellent reliability and moderate to substantial reproducibility for all scales of the questionnaire except two questions for κ statistics. The present study is of great importance, as there are no psychometrically evaluated tools (based on health behaviour models) with accepted validity and reliability for the evaluation of such factors in children with malnutrition. The questionnaire developed in the present study can be used to assess the effect of intervention among primary school students with malnutrition. [ABSTRACT FROM AUTHOR]

Therapy-related symptom checklist for children (TRSC-C) was developed as a symptom assessment tool in children receiving chemotherapy. The objective of the present study was to evaluate the validity and reliability of the Persian version of TRSC-C. This cross-sectional study was conducted in 2013-2014 in Tehran, Iran. TRSC-C was translated using backward-forward approach. The content validity, face validity, and comprehensiveness were investigated based on the opinion of experts. The item content validity index (I-VI) and scale content validity index (S-VI) were calculated by the mean approach and inter-rater agreement. The scale was revised based on the comments from a team of five experts, after which it was evaluated by an additional group of four experts. To assess the inter-rater reliability, two raters filled the scale with 29 and 30 patients in the outpatient clinic of Hara-e Ali Ashlar Hospital. The Coronach's alpha was calculated and factor analysis was performed. The scores of content validity were analyzed in Excel. Other statistical analyses were performed using the SEPSES software version 20.0. Based on the initial assessment, the S-VI with less conservative approach was 60% for clarity, 33% for relevancy, and 60% for simplicity. After revising the scale, the S-VI reached 100%. The comprehensiveness and face validity of the scale were appropriate. The scale was inter-rater reliable and the Coronach's alpha was 0.803. Eleven subscales were found in the TRSC-C. It is concluded that the Persian TRSC-C is a valid and reliable tool for measuring children symptoms. Availability of a valid and reliable checklist is a fundamental step in monitoring the symptoms of patients while receiving chemotherapy. [ABSTRACT FROM AUTHOR]

Introduction: Ethical conflict is one of ICU nurses’ main problems, which rise for several reasons that must be measured. Unfortunately, there is no native instrument for measuring ethical conflicts for ICU nurses in Iran. One of the more suitable and new tools for the measurement of ethical conflict is called the “Ethical Conflict in Nursing Questionnaire: Critical Care Version (ECCNQ-CCV).” This study was aimed to translate and investigate psychometric properties of the ECCNQ-CCV in Iranian nurses. Methods: In this methodological study, after translation and cultural adaptation, face validity, content validity, and construct validity were assessed. Then, internal consistency and stability were measured for reliability. Two software programs (SPSS version 20 and AMOS) were used for data analysis. Result: Face and content validities were acceptable. Confirmatory factor analysis was not fitted. Thus, exploratory factor analysis was done, which showed five factors. However, some of the scenarios in a factor were not compatible with each other, and choosing the fit name for factors was not possible. Thus, all the scenarios were put into one factor, which has been proposed by the developer in the original version. The alpha Cronbach was 0.92 for the total scale. Conclusions: Findings show that the one factor Persian version of the ECNQ-CCV has acceptable psychometric properties. It can be used to evaluate ethical conflicts in Iranian ICU nurses.

Aim To develop an instrument for the assessment of safe nursing care ( ASNC) within the Iranian context and psychometrically evaluate its reliability and validity. Background There is a need for a valid and reliable instrument to assess how nurses employ the components of safe nursing care in clinical practice in non-Western countries. Method This methodological study was conducted in two phases: (1) a qualitative phase of instrument development, and (2) a quantitative phase of psychometric evaluation of the assessment of safe nursing care ( ASNC). The instrument's content validity was assessed by experts in the field of safe nursing care. The reliability of this instrument was examined using internal consistency reliability and intra-rater reliability analysis. Exploratory factor analysis was then conducted to establish the instrument's initial construct validity. Results The instrument developed was a questionnaire with 32 items. The Cronbach's alpha of the scale was 0.92, and Intra-class Correlation Coefficient for intra-rater reliability was 0.78. Exploratory factor analysis resulted in a four-factor solution: (1) evaluation of nursing skills, (2) assessing the patient's psychological needs, (3) assessing the patient's physical need, and (4) Assessing nurses' teamwork. The four factors accounted for 63.54% of the observed variance. Conclusion The ASNC can be applied to a wide variety of settings because of the broad range of methods utilised to generate items and domains, its comprehensive consideration of the principles of safe care, and its initial reliability and validity. Implications for nursing management The ASNC can help nurse managers assess whether clinical nurses are prepared to apply their safe care skills in clinical practice. It can also be used by clinical nurses to assess their own and peers' practice to detect potential areas for improvement in nursing care and help nurse managers with planning appropriate quality improvement programmes.

Background: The aim of this study was to translate and evaluate the validity and reliability of the Nepean Dyspepsia Index (NDI), as a disease-specific quality of life scale in patients with functional dyspepsia. Materials and Methods: Forward-backward translation was done. 80 patients with dyspepsia from the outpatient department of Imam Reza Hospital were assessed. Data were analyzed using SPSS software version 20 and face validity, content validity (CVR)(pls spell out), construct validity (Spearman's rrho), and reliability (test-retest and Cronbach's Alpha) were evaluated. Results: CVR was between 0.80-1, which demonstrated good content validity. Test-retest reliability was good with correlation coefficient of 0.89 and intraclass correlation coefficient of 0.96. Internal consistency revealed α value of 0.93, which was well above the agreeable value of 0.70. These both indicate a good reliability. Spearman's correlation coefficient was 0.48. between all NDI items and subscales which indicates moderate to good construct validity.(it seems that this sentence is not complete because in this format it is meaningless) Conclusion: This study demonstrates that the Persian translation of SF-NDI (pls spell out the highlighted part) is a valid and reliable instrument to measure health related quality of life (HRQoL) in Iranian patients with dyspepsia. It also shows that HRQoL is significantly higher in patients with high school diploma or higher educational levels. [ABSTRACT FROM AUTHOR]

Self-efficacy is an important indicator of a woman's successful transition to her maternal role and an important predictor of a mother's infant care behavior. This study aimed to evaluate the validity of the maternal self-efficacy scale in Iranian mothers. This cross-sectional study was conducted on 437 newly delivered mothers who were referred to health care centers in Bonab, Iran. A simple random sampling was performed. The research instrument included maternal self-efficacy. Translation validity was performed using the forward and backward translation method. Content validity was determined in qualitative (assessment of experts' opinions) and quantitative areas using the content validity ratio (CVR) and Content Validity Index (CVI). Face validity was determined on 30 newly delivered mothers. To determine the construct validity, exploratory factor analysis was used. The reliability was determined in terms of reproducibility via Intra-class correlation coefficient (ICC) by test-retest and internal consistency (Cronbach's alpha). CVI and CVR were 0.91 and 0.94 respectively. Further, the reliability was approved both in terms of reproducibility (ICC = 0.98) and internal consistency (α = 0.89). Construct validity was confirmed using exploratory factor analysis (KMO = 0.90, Bartlett's test p < 0.001) for the scale. The findings supported the validity and reliability of the research instrument. Therefore, it is recommended that the instrument can be used in both clinical practice and research.

In this study, 398 Iranian cancer patients completed the 15-item Templer's Death Anxiety Scale (TDAS). Tests of internal consistency, principal components analysis, and confirmatory factor analysis were conducted to assess the internal consistency and factorial validity of the Persian TDAS. The construct reliability statistic and average variance extracted were also calculated to measure construct reliability, convergent validity, and discriminant validity. Principal components analysis indicated a 3-component solution, which was generally supported in the confirmatory analysis. However, acceptable cutoffs for construct reliability, convergent validity, and discriminant validity were not fulfilled for the three subscales that were derived from the principal component analysis. This study demonstrated both the advantages and potential limitations of using the TDAS with Persian-speaking cancer patients. [ABSTRACT FROM AUTHOR]

• The Persian-translated version of the safety behaviours questionnaire is valid and reliable. • Persian adults who stutter (AWS) frequently use various safety behaviors. • We used a cultural perspective to analyze and interpret the data. • We compared the safety behaviors used by AWS from Anglo and South Asian cultures. Adults who stutter (AWS) are reported to have higher social anxiety compared to those who do not stutter. Previous studies have suggested that safety behaviors, which are cognitive or behavioral strategies used by people with anxiety to prevent negative consequences, are important factors in maintaining anxiety. However, the frequency and types of such behaviors might vary in different cultures. Therefore, the aim of the present study was to develop a transcultural adaptation of Safety Behaviors Questionnaire (Helgadottir et al., 2014) for Persian-speaking AWS and assess its validity and reliability. In the first step, the original English questionnaire was translated into Persian using the International Quality of Life Assessment (IQOLA) method. Then, 17 speech and language pathologists (SLPs) and 5 AWS evaluated all questionnaire items using Likert scales to determine face validity. Finally, 167 Persian-speaking AWS completed the questionnaire to assess its construct validity and reliability. Their responses were analyzed using factor analysis and Cronbach's Alpha. Some items of the original questionnaire were modified or combined with other similar items after assessing the face validity of the Persian-translated questionnaire. Construct validity analysis categorized the remaining 29 questionnaire items into four factors: general avoidance, practice and control, rehearsal, and choosing safe and easy people. The high Cronbach's Alpha of 0.89 for all items confirmed the internal reliability of the Persian-translated questionnaire. The results confirmed the psychometric characteristics of the Persian- translated version of the Safety Behaviors Questionnaire (Helgadottir et al., 2014); therefore, speech pathologists can apply it in future clinical and research settings. Similar to Australian AWS, Persian participants of this study self-reported use of various types of safety behaviors frequently. [ABSTRACT FROM AUTHOR]

Syntax has a high importance among linguistic parameters, and syntax-related problems are the most common in language disorders. Therefore, the present study aimed to design a Photographic Expressive Persian Grammar Test for Iranian children in the age group of 4–6 years and to determine its validity and reliability. First, the target morphosyntactic structures among Persian-speaking 4–6-year-old children were extracted, and items related to each structure were designed. After both content and face validity were determined and modifications were applied, the initial version of the test was performed on 100 children. The final version of the test was performed on 400 eligible, typically-developing children selected using the random (cluster) method. Psychometric properties investigated in this study include construct validity (convergent validity and age and gender discriminative validity) and reliability (test–retest, inter-rater, and internal consistency). Content validity of each item was between 0.8 and 1, and content validity of the whole scale was 0.86. Exploration of construct validity suggested that age and gender affect the test scores. Convergent validity was found to be significant. Results of test–retest, and inter-rater reliability were significantly correlated and the test was found to have high internal consistency. The Photographic Expressive Persian Grammar Test with 40 items is the first reliable and valid scale that exclusively and accurately evaluates morphosyntactic characteristics of 4–6-year-old Persian-speaking children.

Background: Moderate increase in physical activity (PA) may be helpful in preventing or postponing the complications of type 2 diabetes mellitus (T2DM). The aim of this study was to assess the psychometric properties of a health action process approach (HAPA)-based PA inventory amongT2DM patients. Methods: In 2015, this cross-sectional study was carried out on 203 participants recruited by convenience sampling in Isfahan, Iran. Content and face validity was confirmed by a panel of experts. The comments noted by 9 outpatients on the inventory were also investigated. Then, the items were administered to 203 T2DM patients. Construct validity was conducted using exploratory and structural equation modeling confirmatory factor analyses. Reliability was also assessed with Cronbach alpha and interclass correlation coefficient (ICC). Results: Content validity was acceptable (CVR = 0.62, CVI=0.89). Exploratory factor analysis extracted seven factors (risk- perception, action self-efficacy, outcome expectancies, maintenance self-efficacy, action and coping planning, behavioral intention, and recovery self-efficacy) explaining 82.23% of the variation. The HAPA had an acceptable fit to the observations (χ² = 3.21, df = 3, P = 0.38; RMSEA = 0.06; AGFI = 0.90; PGFI =0.12).The rangeof Cronbach alpha and ICC for the scales was about 0.63 to 0.97 and 0.862 to 0.988, respectively. Conclusion: The findings of the present study provided an initial support for the reliability and validity of the HAPA-based PA inventory among patients with T2 DM. [ABSTRACT FROM AUTHOR]

Background: At present, there are no comprehensive validated instruments for measuring adolescents' beliefs regarding tobacco smoking in the Iranian society. This study aimed to evaluate the validity, reliability and feasibility of the belief- based tobacco smoking scale using the Theory of Planned Behavior's (TPB) constructs as a theoretical framework. Methods: This cross-sectional validation study was carried out on 410 male adolescents of Hamadan, west of Iran, recruited through multi-stage random sampling method. Reliability was assessed by internal consistency and Intraclass Correlation Coefficient (ICC). In addition, Confirmatory Factor Analyses (CFA) and Exploratory Factor Analyses (EFA) were performed to test construct validity. Content validity was examined using Content Validity Index (CVI) and Content Validity Ratio (CVR). Results: Results obtained from factor analysis showed that the data was fit to the model (χ²=391.43, P<0.001) and TPB consisted of 22 items measuring seven components which explaining 69.7% of the common variance. The mean scores for the CVI and CVR were 0.89 and 0.80; respectively. Additional analyses indicated acceptable results for internal consistency reliability values ranging from 0.55 to 0.92. Conclusion: The belief-based tobacco smoking questionnaire is a reliable and valid instrument and now is acceptable and suitable and can be used in future studies. [ABSTRACT FROM AUTHOR]

Background: Designing cancer prevention programs needs information on knowledge, attitude, and practice of the community. Unfortunately, this information is not available in Iran. Materials and Methods: We developed a questionnaire (NUTCANKAPQ) to assess the knowledge, attitude, and practice of Iranian women regarding cancer prevention dietary habits. We recruited women who had referred to public health-care centers in Tehran, Iran. To assess validity, we applied face, content, and construct validity methods. We performed test–retest approaches to assess reliability, and internal consistency of the questionnaire was assessed through Cronbach's alpha and intraclass correlation coefficients (ICCs). Results: Qualitative content validity was carried out by an expert panel, and internal consistency was deemed satisfactory (Cronbach's alpha, >0.6). We also observed high reliability in the questionnaire (ICC = 0.85). The mean (± standard deviation) scores for knowledge, attitude, and practice of study participants were 28.3 (±14.1), 67.1 (±18.9), and 53.7 (±8.3), respectively. The result of exploratory factor analysis, Kaiser–Meyer–Olkin (KMO), implied that the model was reasonably fit (KMO > 0.6). The final questionnaire included seventy items. Conclusion: NUTCANKAPQ is a valid and reliable tool for the assessment of cancer-related nutrition knowledge, attitude, and practice among the Iranian population. Application of NUTCANKAPQ may provide important clues for policy-making and improvement of cancer prevention programs among the Iranian population. [ABSTRACT FROM AUTHOR]
