Background: The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives: The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to assess the reliability and validity of the translated version. Material & Methods: 110 patients participated in this survey. The internal consistency tests were calculated using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects, and responsiveness were calculated. Bland-Altman Plot and forest plots were done to measure the level of agreement. Results: Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively).

Abstract Background The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to further assess the reliability and validity of translated version Material & Methods 110 patients participated in this survey. The internal consistency tests were performed using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects and responsiveness was also calculated. In order to measure the level of agreement, Bland-Altman Plot, forest Plots are performed. Results Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively). This only proves that WOMAC is an instrument with good reliability. Same calculation of Cronbach’s alpha was essential to testing the reliability of the Harris Hip Score. For each of the three testing occasions the reliability was very good or excellent – α 1 = 0.92, α 2 = 0.91, and α 3 = 0.90. Intra-class correlation coefficient was good with the score of 0.76 (95% CI 0.44-0.88). Conclusion Overall, Arabic version of HOOS could be used as diagnostic tool for patients with hip problems, when it comes to information about the overall condition of the patient, especially about the improvement or deterioration, however, it is important to be cautious using HHS when the change magnitude of patient’s condition is investigated, since there is a potential probability that the level of improvement of the patient’s condition will be overestimated by HHS.

Abstract Background: Parents of children with autism spectrum disorder (ASD) are known to poorer quality of life. The Quality of Life in Autism Questionnaire (QoLA) is a commonly used instrument for measuring the quality of life in parents of children with ASD. The aim of this study was to evaluate the reliability and validity of the QoLA in Iranian mothers of children with ASD.Methods: The sample of this methodological study consisted of 88 mothers of children with ASD in Arak, Iran. The data were collected using convenience sampling method between September 2019 and January 2020. A battery of questionnaires was administered to mothers which included the QoLA, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale-4 (PSS-4). Factor structure and internal consistency of the QoLA were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with WHOQOL-BREF, PHQ-9, GAD-7 and PSS-4.Results: The mean total scores of QoLA Part A and Part B were 86.50 (SD=13.89) and 61.41 (SD=18.21), respectively. Both subscales exhibited good internal validity (with Cronbach’s alpha of 0.899 and 0.950 for Part A and Part B, respectively). The convergent validity of both subscales of QoLA was proved via moderate to strong correlations with measure of the WHOQOL-BREF. In addition, both QoLA Part A and Part B scores were negatively correlated with measures of PHQ-9, GAD-7, and PSS-4. The confirmatory factor analyses provided evidence for unidimensionality of both subscales of QoLA.Conclusion: The Persian version of QoLA displays satisfactory reliability and validity in Iranian mothers of children with ASD.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.

Multiplanar Reconstructions

Background: Intracerebral hemorrhage (ICH) volume calculation using ABC/2 method is well established and is widely used. Modifications of the method have been proposed which can make hematoma volume measurement faster. Helical computed tomographic (CT) techniques with multiplanar reconstructions allow direct measurement of the antero-posterior (AP), transverse (TV) and craniocaudal (CC) diameters, thereby allowing calculation of the hematoma volume using a modified ABC/2 method. We investigated the reliability of the modified ABC/2 technique of ICH volume measurement. Method: Forty-one consecutive patients with ICH were identified from a 6-month period following review of the medical records. A board-certified neurologist used the established ABC/2 formula, while a board-certified neuroradiologist used the modified ABC/2 formula to calculate the ICH volumes. The neuroradiologist took the AP measurements off the axial section while TV as well as CC measurements off the coronal images. Statistical analysis was performed. Results: The neuroradiologist took significantly less time (9 ± 3seconds) in measuring the volumes as opposed to the neurologist (44 ± 12 seconds), p<0.001. The average ICH volume as measured by the neurologist (13.2 ± 16.4 cc) was significantly smaller than the neuroradiologist measured ICH volume (19 ± 32 cc), p <0.001. When hematoma volume was dichotomized with 30 cc as the cutoff, the examiners agreed on volumes of < 30 cc more often (95%) than the volumes of > 30 cc (66%). The volumes measured using the two methods were significantly correlated (r= 0.85, p<0.001) with a high inter-rater reliability (Cronbach’s alpha= 0.82, ICC= 0.8). For individual dimensions, the agreement was least for TV diameters (Cronbach’s alpha = 0.7, ICC= 0.7) and highest for AP diameters (Cronbach’s alpha = 0.95, ICC= 0.95). Conclusion: The modified ABC/2 formula can quickly and reliably measure the hematoma volume based on our findings. We plan to test reliability and validity further with a larger examiner pool before its routine clinical application is suggested.

Nurses Perceptions

Every year approximately 4 million women in the United States experience childbirth. This event has been cited as pivotal in a woman’s life. Labor support is an important part of this experience since it influences the woman’s classification of the birth experience as positive or negative. Therefore, understanding how intrapartum nurses perceive the role of supportive care during labor is paramount. The purpose of this study was to develop a reliable and valid instrument that measures intrapartum nurses’ perceptions concerning the importance of professional labor support in their practice. The sample included 146 intrapartum nurses from Texas. Cronbach’s alpha, Pearson’s r, and descriptive statistics were used for data analysis. Cronbach’s alpha for the Labor Support Questionnaire (LSQ) was 0.90. Convergent validity with the Caring Behavior Inventory was .57 (p < .001). Findings indicated beginning support for the reliability and validity of the LSQ. Further development and psychometric testing is recommended to ascertain the dimensionality of the LSQ.

Objective: To examine aspects of the reliability and validity of the Reynolds Adolescent Depression Scale (RADS) in measuring depression in New Zealand adolescents of all major ethnic groups. Method: A sample of 9699 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey which included the RADS. Data from this survey have been used to assess some aspects of the reliability and validity of the RADS in the New Zealand context across different ethnic groups. Cronbach's alpha, itemtotal score correlations, correlation to other questions and a factor analysis were done in order to examine the internal reliability, content validity, convergent validity and construct validity of the data and compare to the original Reynolds validation study. Results: Tests of the scale resulted in scores over 0.90 on Cronbach's alpha and high itemtotal score correlations, with a median correlation of 0.62 and 25 of the 30 correlations measuring more than 0.5. The scores were found to have similar factor structure to the original scale and the correlations to other depression related questions indicate acceptable concurrent validity. Conclusions: On all of the tests conducted, the RADS was found to have acceptable reliability and validity for New Zealand adolescents across the major different ethnic groups, indicating that it is a valid and appropriate instrument to use with New Zealand adolescents.

Background: National Institute of Health Stroke Scale (NIHSS) and Modified National Institute of Health Stroke Scale (mNIHSS) are two valid and reliable questionnaires that assess stroke severity. This study aimed to examine and compare the validity and reliability of Persian versions of NIHSS and mNIHSS in hospitalized patients. Materials and Methods: The English versions of NIHSS and mNIHSS were translated to Persian (forward and backward), and three neurologists examined the face and content validity of both questionnaires. The Persian versions of NIHSS and mNIHSS were used in75 hospitalized stroke patients (hemorrhagic and obstructive) admitted to Namazi teaching hospital, Shiraz, Iran.The reliability and validity of the Persian versions were examined by Cronbach's alpha coefficient and convergent validity. Result: The values of Cronbach's alpha for Persian versions of NIHSS and mNIHSS were 0.81 and 0.86, respectively. The scaling success of convergent validity in NIHSS and mNIHSS were 80% and 100%, respectively. Conclusion: The Persian versions of NIHSS and mNIHSS were reliable and valid. However, mNIHSS was more valid and reliable than NIHSS. Persian version of mNIHSS can be suggested to be used for assessing stroke severity in hospitalized stroke patients by neurologists and researchers. [GMJ. 2019;8:e1188]

Background: Academic stress is one of the factors affecting the health of adolescents. The aim of present study was to design an academic stress questionnaire for Iranian adolescents with regard to the cultural and educational system of the country. Methods: After reviewing the literature and identifying available tools in 2018, Iranian adolescents' views on academic stress were extracted. Similar questions have been used in other tools. According to expert opinion, the results were overviewed and the initial version was designed. The steps of content validity and instrument reliability were carried out. Internal consistency was investigated with Cronbach's alpha (α) and repeatability with Intra Class Correlation (ICC). After dividing the data into two randomized samples, exploratory factor analysis (EFA) with 899 subjects and confirmatory factor analysis (CFA) with 717 subjects were performed. The association between this tool and the Morgan and Jink’s Self Efficacy Scale and the Strengths and Difficulties Questionnaire questionnaires was investigated. Data were analyzed using SPSS and Mplus softwares. Results: The Iranian Adolescent Academic Stress Questionnaire (IAASQ) was designed with 57 questions. Relevancy and clarity of the whole tool were obtained as 0.81 and 0.83, respectively. In different domains, Cronbach's alpha was in the range (0.58-0.85) and ICC (0.80 (95% CI:0.66-0.90)). In the EFA, 9 factors were extracted. CFA confirmed the suitability of the model in another sample. Discriminant and convergent validity tool was approved. Conclusion: The IAASQ questionnaire has acceptable reliability and validity. This tool is recommended for use in related studies in the Iranian community.

Introduction. The malocclusion index questionnaire (MIQ) is widely used in research and clinical practice. To our knowledge, there are no studies of its use in Moroccan patients. Aim. The objective of this study was to translate and culturally adapt the malocclusion impact questionnaire (MIQ) into Moroccan Arabic and to assess its reliability and validity among a sample of young Moroccan teenagers. The PIDAQ was cross-culturally adapted into Malay version by forward- and backward-translation processes, followed by psychometric validation. Materials and Methods. The MIQ was cross-culturally adapted into Moroccan Arabic by forward- and backward-translation processes, followed by psychometric validations. The MIQ was completed by a representative sample of 94 Moroccan adolescents aged 12–17 years selected randomly from five public schools of Casablanca. Internal consistency reliability was determined from Cronbach’s alpha, and the intraclass coefficient of the item scores was obtained in 1 month in a subset of 30 subjects. Data were analyzed using the Statistical SPSS software, version 16.0, SPSS Inc, Chicago, IL, USA. Results. The MIQ was completed twice by each participant at one-month interval to assess test reliability; the intraclass coefficient was r = 0.958, showing an excellent reproducibility. The internal consistency demonstrated the reliability of the questionnaire with Cronbach’s alpha coefficient of 0.917. The validity of the questionnaire was assessed by evaluation of the relationship between the total scores of the MIQ and normative need for orthodontic treatment according to ICON. The questionnaire showed an insignificant correlation (0.129, p<0.05). Conclusion. The Moroccan Arabic version of the MIQ was found to be reliable, whereas it has unacceptable validity according to ICON, and hence, it is unlikely to be a useful measure in orthodontic clinical trials for Moroccan adolescents.
