Abstract Purpose To develop an Arabic version of the CPQ8–10 and test its validity and reliability for use among Arabic-speaking children. Methods The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8–10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test–retest reliability were assessed using Spearman’s rank correlation coefficients, Cronbach’s alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed. Results CPQ8–10 scores and global ratings were positively correlated. CPQ8–10 scores were highest in group II, followed by groups I and III, respectively. CPQ8–10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach’s alpha was 0.95 and the intraclass correlation coefficient was 0.97. Conclusions The Arabic CPQ8–10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.

Heart Failure Questionnaire

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) has been developed to measure health-related quality of life (HRQoL) status of Heart Failure (HF) patients. The aim of this study was to translate MLHFQ into the Persian version and assess the validity and reliability of the translated version. We used a forward-backward procedure for translation. In a cross-sectional study, 105 HF patients and 50 healthy subjects were selected to assess the reliability and construct validity of the instrument. The face and content validity were used to assess the questionnaire validity. Validity was examined on the HF patients group, using the Persian version of the Short form-36 health survey (SF-36) Questionnaire. In order to assess the questionnaire’s reliability, the Intraclass correlation coefficient (ICC) and Cronbach’s alpha were calculated. Test-retest reliability was examined by re-administering the MLHFQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all 2 domains were higher than 0.91, P≤0.000). Internal consistency for Physical domain (PD), emotional domain (ED) and total scores using Cronbach’s alpha were 0.90, 0.84 and 0.92, respectively. ICC for PD, ED and total scores were 0.95, 0.94, and 0.97, respectively. Good and very good Pearson's Correlation Coefficient was seen between MLHFQ and SF-36 (r= -0.47 to -0.775, P≤0.000 for PD; r= -0.47 to -0.65, P≤0.000 for ED). The Persian version of the MLHFQ had satisfactory reliability and validity for assessing HRQoL status of Iranian HF patients. © 2019 Tehran University of Medical Sciences. All rights reserved.

Abstract Background: Occupational back pain is the most prevalent health problem among nurses and needs to be assessed by a valid and multi-factorial questionnaire. The purpose of the present study was to design and develop an instrument based on the PRECEDE-PROCEED model for assessing job-related behaviors that cause low back pain. Methods: First an item pool of 49 items was generated. Then, content and face validity was carried out. Consequently, a cross-sectional study was conducted in Mazandaran, Iran. The questionnaire was distributed among a sample of nurses working in hospitals affiliated to Mazandaran University of Medical Sciences. Exploratory factor analysis was used to determine the factor structure of the questionnaire. The Cronbach’s alpha was estimated to assess the reliability and the intraclass correlation coefficient was calculated to examine stability. Results: In all 155 nurses participated in the study. The mean age of respondents was 34.1 (SD = 7.66) years, and 83.2% were female. Six factors with 30 items emerged from the exploratory factor analysis: knowledge, attitude, self-efficacy, reinforcing factors, enabling factors and behavior that jointly accounted for %66.5 of behavior change variance observed. The Cronbach’s alpha coefficient showed excellent internal consistency (alpha=0.92). The intraclass correlation coefficient with 2-weeks interval also indicated that the questionnaire has satisfactory stability (ICC = 0.97). Conclusions: The findings showed that the Occupational Back Pain Prevention Behavior Questionnaire is a reliable and valid instrument for measuring occupational back pain and prevention behaviors among nurses.

Abstract Background Given the importance of the childbirth experience, its effects on women’s life and society, and the need for its assessment by accurate instruments, this study aimed to determine the psychometric properties of the Questionnaire for Assessing the Childbirth Experience (QACE) in an Iranian women population. Methods The validity of the Farsi edition of the questionnaire was assessed using the opinions of eight experts. Its construct validity was assessed by studying 530 mothers, at 1–4-month postpartum, who delivered in health centers of Tabriz, Iran. The exploratory factor analysis (EFA) was performed to identify its factors. Then, the confirmatory factor analysis (CFA) was performed for the structural assessment of the extracted factors. Spearman’s correlation coefficient was used to investigate the correlation between factors. Cronbach’s alpha and intraclass correlation coefficient (ICC) were used to obtain the internal consistency and test-retest reliability. Results In total, four factors were extracted from the EFA: “relationship with staff” (4 questions), “first moments with the newborn” (3 questions), “feelings at one-month postpartum” (3 questions), and “emotional status” (3 questions). According to the CFA, the model achieved desired fit level (RMSEA < 0.08, GFI, CFI, IFI > 0.90, and x2/df < 5.0). Cronbach’s alpha (0.77–0.82) and intraclass correlation coefficient index (0.83–0.98) were desirable for all factors. Conclusion The short edition of the QACE, as a standard tool, can be used by future studies to measure the experience of Iranian women.

Disgust Propensity

Η αηδία έχει αναγνωριστεί ως ένα από τα βασικά συναισθήματα από αρκετούς ερευνητές και σε διάφορους πολιτισμούς. Τα τελευταία χρόνια το βασικό συναίσθημα της αηδίας έχει προσελκύσει έντονο ερευνητικό ενδιαφέρον. Ορίζεται ως ο αποτροπιασμός που προκαλείται στην προοπτική ενσωμάτωσης από το στόμα ενός απεχθούς αντικειμένου και από εξελικτική σκοπιά θεωρείται πως έχει εξελιχθεί ως ένα ψυχολογικό σύστημα προστασίας του οργανισμού από μόλυνση μέσω της αποφυγής πιθανών πηγών μόλυνσης. Η συχνότητα και ευκολία κατά την οποία κάποιος μπορεί να νιώσει αηδία ορίζεται ως Τάση για Αηδία (Disgust propensity). Η τάση για αηδία έχει συνδεθεί με διάφορες μορφές ψυχοπαθολογίας όπως η Ιδεοψυχαναγκαστική Διαταραχή με ιδεοληψίες μόλυνσης, Ειδικής Φοβία Αράχνης, Ειδική Φοβία Αίματος Τραύματος-Ένεσης, Διαταραχές Πρόσληψης Τροφής, Σχιζοφρένεια και Μετατραυματική Διαταραχής Στρες μεταξύ άλλων. Ως εκ τούτου, ένα έγκυρο εργαλείο μέτρησης της τάσης για αηδίας καθίσταται αρκετά χρήσιμο στη κλινική πράξη καθώς μπορεί να χρησιμοποιηθεί στην περεταίρω διερεύνηση των συμπτωμάτων. Η Αναθεωρημένη Κλίμακα της Αηδίας (DS-R) (Olatunji et al., 2007) έχει κατασκευαστεί για την μέτρηση της τάσης για αηδία και αποτελείται από τρεις διαστάσεις: την Πυρηνική Αηδία, την Αηδία Μόλυνσης, και την Υπενθύμιση Ζώων. Καθώς έχει αρκετά ικανοποιητικές ψυχομετρικές ιδιότητες και έχει χρησιμοποιηθεί σε μελέτες που εξετάζουν την σχέση της αηδίας με συμπτώματα ψυχοπαθολογίας και άλλα χαρακτηριστικά, η συγκεκριμένη κλίμακα επιλέχθηκε για στάθμιση στον Ελληνικό πληθυσμό. Στόχος της παρούσας διατριβής ήταν να διερευνήσει το συναίσθημα της αηδίας στον Ελληνικό πληθυσμό και να εξετάσει τις ψυχομετρικές ιδιότητες της ελληνικής εκδοχής της DS-R. Συνολικά 754 συμμετέχοντες από όλα τα μέρη της Ελλάδας έλαβαν μέρος στη μελέτη. Επίσης, 363 από τους συμμετέχοντες συμπλήρωσαν, επίσης, την Αναθεωρημένη Κλίμακα Ψυχοπαθολογίας (SCL-90-R) και το ερωτηματολόγιο προσωπικότητας του Eysenck (EPQ), ώστε να εξεταστεί η συντρέχουσα εγκυρότητα. Η παραγοντική δομή της κλίμακας εξετάστηκε με την εφαρμογή της Διερευνητικής και της Επιβεβαιωτικής Παραγοντικής Ανάλυσης. Επίσης, πραγματοποιήθηκε χρήση του μοντέλου πολλαπλών δεικτών και πολλαπλών αιτιών (MIMIC) προκειμένου να διερευνηθούν οι επιδράσεις του φύλου και της ηλικίας στα ερωτήματα. Οι διαφορές των μέσων όρων των βαθμολογιών μεταξύ ομάδων των δημογραφικών στοιχείων αξιολογήθηκαν με t-test ανεξάρτητων δειγμάτων (μέχρι δύο ομάδες) και ανάλυση διακύμανσης μονής κατεύθυνσης, one-way ANOVA (πάνω από δύο ομάδες). Τέλος, για την εξέταση της αξιοπιστίας της κλίμακας χρησιμοποιήθηκαν ο δείκτης εσωτερικής συνέπειας Cronbach’s alpha και ο συντελεστής ενδοσυσχέτισης (intraclass correlation coefficient, ICC) για την αξιοπιστία επαναλαμβανόμενων μετρήσεων. Η Διερευνητική παραγοντική ανάλυση ανέδειξε δύο μοντέλα, ένα δι-παραγοντικό και ένα τρι-παραγοντικό που θυμίζουν αρκετά εκείνα που έχουν προταθεί από την βιβλιογραφία. Ωστόσο, παρατηρήθηκαν κάποιες διαφορές μεταξύ του τρι-παραγοντικού μοντέλου της παρούσας μελέτης με εκείνο που προτάθηκε από τη βιβλιογραφία καθώς οι δύο παράγοντες συμπεριλάμβαναν ερωτήματα από την Πυρηνική αηδία και αηδία μόλυνσης. Η Επιβεβαιωτική Παραγοντική ανάλυση έδειξε πως το τρι-παραγοντικό μοντέλο έχει καλή εφαρμογή στα δεδομένα ενώ η ανάλυση του διττού αντίστοιχου μοντέλου ανέδειξε τη σημαντικότητα του γενικού παράγοντα της αηδίας. Το φύλο και η ηλικία είχαν επιδράσεις σε κάποια ερωτήματα. Επίσης, η αξιοπιστία της κλίμακας ήταν αρκετά ικανοποιητική. Όσον αφορά τα δημογραφικά χαρακτηριστικά, οι γυναίκες είχαν μεγαλύτερες βαθμολογίες σε όλες τις υποκλίμακες της DS-R ενώ ο βαθμός της θρησκευτικότητας συσχετίζονταν με τις βαθμολογίες στην κλίμακα. Τέλος, οι συσχετίσεις μεταξύ της DS-R και των υποκλιμάκων των EPQ και SCL-90-R στηρίζουν την αποκλίνουσα και συγχρονική εγκυρότητα της κλίμακας. Η παρούσα μελέτη έδειξε πως η ελληνική εκδοχή της DS-R έχει ικανοποιητικά ψυχομετρικά χαρακτηριστικά. Επομένως, αυτή η κλίμακα μπορεί να χρησιμοποιηθεί για κλινική και ερευνητική χρήση στον Ελληνικό πληθυσμό. Ωστόσο, η μελέτη ανέδειξε κάποια πιθανά προβλήματα της παραγοντικής δομής της κλίμακας και την ανάγκη για περαιτέρω διερεύνηση και αναθεώρηση από μελλοντικές μελέτες.

Introduction:Disasters are situations of complexity and unpredictability that require the performance of teams from various instances with preparation and qualification to assist the victims, recover the environment, and restore living conditions. Health services are essential in the response to a disaster, and nurses all over the world play a significant role in these disasters.Aim:To develop a valid and reliable scale to identify nursing competencies in disasters.Methods:Competencies were selected from those related to the framework developed by the International Council of Nurses. A methodological study was developed in two stages: I) validity of content and appearance verification and II) verification of applicability and reliability with test-retest. The participants of stage I were eight specialists in emergencies and disasters in Brazil. In stage II, 326 nurses from the Emergency Mobile Assistance Service in Southern Brazil participated. Data analysis utilized the Content Validity Index and Interest Reliability Index. Psychometric properties of the instrument were measured with Cronbach’s alpha coefficient; applicability and test-retest reliability with the use of the t-test and intraclass correlation coefficient and factorial validity.Results:Forty-one competencies of 51 were organized in three domains according to Factor Analysis. Cronbach’s alpha values showed good internal consistency. There was no significant difference between the test and retest scores. The intraclass correlation coefficient values were adequate. The instrument showed reproducibility and adequate applicability.Discussion:This tool will assess nurses’ competencies for disaster response and provide evidence for the development of educational policies in disasters, creating a reliable and prepared workforce to respond more effectively during a disaster.

AbstractThis study aimed to translate and adapt the Intermittent and Constant Osteoarthritis Pain questionnaire into the Arabic language and evaluate the validity and reliability of this scale for participants with knee or hip osteoarthritis. This questionnaire was translated based on the Manufacturers Alliance for Productivity and Innovation protocol. The test-retest reliability was calculated using the Intraclass Correlation Coefficient. Then, Cronbach’s alpha was used to assess the internal consistency of Intermittent and Constant Osteoarthritis Pain questionnaire. After that, the criterion validity was evaluated against the Knee injury and Osteoarthritis Outcome Score. A total of 90 participants were included in this study, of which 29 participants were re-evaluated for reliability testing. The Intraclass Correlation Coefficient of the Knee Intermittent and Constant Osteoarthritis Pain questionnaire were 0.841, 0.923 and 0.911 for the total, constant, and intermittent knee pain, respectively. Cronbach’s alpha was 0.88, 0.93 and 0.94 for the total score, the intermittent knee pain and the constant knee pain, respectively. Eventually, criterion validity was r=0.24(P<0.05). Intermittent and Constant Osteoarthritis Pain in Arabic is a valid and reliable instrument to be used in Arabic-speaking patients with knee/hip osteoarthritis.

Introduction: Modified Euro Quest questionnaire to assess neurological and psychiatric effects caused by exposure to organic solvents is used. This study investigates the validity, reliability, and usability of the modified Euro Quest questionnaire in Iran. Materials and Methods: This cross-sectional descriptive study was conducted on 206 workers of color and textile industries. Modified Euro Quest questionnaire was translated into Persian by using the forward-backward translation standard method. To evaluate the content validity, convergent validity, internal consistency, and reliability of the questionnaire were used the index CVI, Pearson correlation coefficient, Cronbach's alpha, and test-retest. The convergent validity was compared, results of the questionnaire, with results of mini-mental state examination (MMSE) and Multidimensional Fatigue Inventory (MFI). Results: The relationship between the modified Euroquest questionnaire was compare with the MMSE test and the MFI's questionnaire, Pearson correlation coefficients, and the results showed in order - 0.86 and 0.65, which represents a significant inverse correlation between this questionnaire with MMSE test(p>0.001) And a moderate correlation with the MFI's questionnaire(p>0.001). Content validity index (CVI) and intraclass correlation coefficient (ICC) were obtained in order amounts of ≤0.79 and 0.92, which was acceptable. The final questionnaire, Cronbach's alpha coefficient, was calculated (α =0.84).  Conclusion: The modified Euroquest Persian version is a valuable tool to assess the neurological and psychological effects caused by exposure to organic solvents in Iranian workers.

Oxford Elbow Score (OES) is a patient-reported questionnaire used to assess outcomes after elbow surgery. The aim of this study was to validate and adapt the OES into Persian language. After forward-backward translation of the OES into Persian, a total number of 92 patients after elbow surgeries completed the Persian OES along with the Persian DASH and SF-36. To assess test-retest reliability, 31 randomly selected patients (34%) completed the Persian OES again after three days while abstaining from all forms of therapeutic regimens. Reliability of the Persian OES was assessed by measuring intraclass correlation coefficient (ICC) for test-retest reliability and Cronbach’s alpha for internal consistency. Spearman’s correlation coefficient was used to test the construct validity. Cronbach’s alpha coefficient was 0.92 showing excellent reliability. Cronbach’s alpha for function, pain, and social-psychological subscales was 0.95, 0.86, and 0.85, respectively. Intraclass correlation coefficient (ICC) was 0.85 for the overall questionnaire and 0.90, 0.76, and 0.75 for function, pain, and social-psychological subscales, respectively. Construct validity was confirmed as the Spearman correlation between OES and DASH was 0.80. Persian OES is a valid and reliable patient-reported outcome measure to assess postsurgical elbow status in Persian speaking population.

Objectives To validate the systemic lupus activity questionnaire (SLAQ) in Spanish language. Methods The SLAQ questionnaire was translated and adapted in Spanish. Consecutive SLE patients from 8 centers in Argentina were included. A rheumatologist completed a Systemic Lupus Activity Measure (SLAM), Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K, and a physician’s assessment. Reliability was assessed by internal consistency (Cronbach’s alpha), stability by test–retest reliability (intraclass correlation coefficient), and construct validity by evaluating the correlation with clinically relevant scores. Sensitivity and specificity for clinically significant disease activity (SLEDAI ≥6) of different S-SLAQ cut-off points were evaluated. Results We included 97 patients ((93% female, mean age: 40 years (SD14.7)). Internal consistency was excellent (Cronbach’s alpha = 0.84, p < 0.001), and the intraclass correlation coefficient was 0.95 ( p < 0.001). Mean score of S-SLAQ was 8.2 (SD 7.31). Correlation of S-SLAQ was moderate with Patient NRS (r= 0.63 p< 0.001), weak with SLAM-no lab ( r = 0.42, p <0.001) and SLAM ( r = 0.38, p < 0.0001), and very weak with SLEDAI-2K ( r = 0.15, p =0.1394). Using the S-SLAQ cutoff of five points, the sensitivity was 72.2% and specificity was 37.9%, for clinically significant disease activity. Conclusions The S-SLAQ showed good validity and reliability. A good correlation, similar to the original instrument, was observed with patient´s global disease activity. No correlation was found between S-SLAQ and gold standard disease activity measures like SLEDAI-2K and SLAM. The S-SLAQ cutoff point of 5 showed a good sensitivity to identify the active SLE population and therefore could be an appropriate screening instrument for disease activity in clinical and epidemiological studies.
