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.

Abstract Background Patients receiving hemodialysis (HD) often experience multiple symptoms concurrently and these symptoms may impact their quality of life. A valid and reliable tool is needed to assess the symptom distress of patients receiving HD in terms of the perspective of symptom clusters. Although many studies have explored symptom clusters related to patients receiving HD, the clusters formed had problems with overlapping, vagueness, lack of cluster-specificity, and difficulty in discerning their common mechanism under the cluster. Aims To develop reliable measurement tool to identify the symptom clusters of patients undergoing HD. Design A cross-sectional descriptive study. Methods To examine the physiological properties of the HD symptom distress (HSD) scale, 216 participants were recruited from a HD center of a medical university hospital in southern Taiwan from February 2019 to April 2019. Construct validity was evaluated by exploratory factor analysis (EFA), and the internal consistency and test–retest reliability were estimated by Cronbach’s alpha and intraclass correlation coefficient (ICC). Results The CVI value of the HSD was 0.89. The HSD scale was composed of five factors with 22 items, including insufficient energy/vitality, cardiac–pulmonary distress, sleep disturbance, musculoskeletal distress, and gastrointestinal distress, with factor loading ranging from 0.62 to 0.87, explaining 65.5% of the total variance. Cronbach’s alpha coefficient of the HSD total scale was 0.93, and five subscales ranged from 0.73 to 0.89. The test-retest reliability was 0.92 (p < 0.001) by using the intraclass correlation coefficient (ICC) for the HSD-22 scale. Conclusion / implication Theoretical testing from our study indicated that the HSD-22 scale had satisfactory validity and reliability. Therefore, this assessment tool can be employed to identify the symptom clusters of patients receiving HD in the clinical setting. Such identification enables healthcare professionals to provide interventions to release patients’ symptom distress efficiently.

Abstract OBJECTIVE The purpose of this study was to develop and test the psychometric properties of the Self-efficacy Scale for the Establishment of Good Relationships with Families in Neonatal and Pediatric Hospital Settings. METHOD Methodological study grounded on self-efficacy theory was conducted in three phases: conceptual and operational definition (review of the literature and interviews with the target population), content validity (opinion of five experts e three clinical nurses), and exploratory factor analysis and internal consistency reliability (cross-sectional survey with a valid sample of 194 nurses). RESULTS A ten-point Likert scale with 40-item was designed and one item was excluded after review by experts. Three factors emerged from the exploratory factor analysis. The Cronbach's alpha for all items was 0.983 with item-total correlations in the range 0.657 to 0.847. Cronbach's alpha value if item deleted were less than or equal to 0.983. CONCLUSION The final version of the scale demonstrated psychometric adequacy. It is a useful tool to be administered in the clinical, educational and research nursing fields to measure nurses’ self-efficacy beliefs concerning the establishment of good relationships with families.

Abstract Addressing physical activity (PA) barriers is an essential component of increasing PA among the 56-73% of community-dwelling adults 50 years and older who are not performing the recommended 150 minutes of moderate-to-vigorous PA. As there is no feasible, multi-factorial tool to assess PA barriers among this population, we developed and validated a PA barrier assessment tool called the Inventory of Physical Activity Barriers (IPAB). We collected cross-sectional data on 503 adults (mean age 70.1), with 79 participants completing the scale twice for test-retest reliability and 64 completing a cross-over design examining the ability to use two administration formats interchangeably. Our analyses consisted of exploratory and confirmatory factor analysis, Cronbach alpha, intraclass correlation coefficient, Bland-Altman Plot, and t-tests. Using factor analysis, we identified and confirmed an eight-factor solution consisting of 27 items. The 27-item IPAB is internally consistent (alpha= 0.91), has a high test-retest reliability (intraclass correlation coefficient=0.99), and can differentiate between individuals who meet the recommended levels of PA and those who do not (p &lt; 0.001). The IPAB scores ranged between 1.00-3.11 for the paper format (mean=1.78) and 1.07-3.48 for the electronic format (mean=1.78), with no statistical difference between the paper and electronic administration formats (p=0.94), resulting in the conclusion that the two administration formats can be used interchangeably. Participant feedback illustrates that the IPAB is easy to use, has clear instruction, and is an appropriate length. The newly validated IPAB scale can be used to develop individualized PA interventions that address PA barriers among patients 50 years and older.

Background and objectives Nurses’ caring behaviors, professional activities, and behaviors for the benefit of patients, influence patients’ perception of care and satisfaction with the quality of care provided. Caring behaviors of nurses are contextual and various factors such as patients’ social structure, lifestyle, culture, and interests, as well as their biographical, social, and physiological characteristics, can influence perceptions of caring behaviors of nurses, as caring behaviors are an interactive and mental process between patients and nurses. This study was conducted to provide a transcultural translation and psychometric analysis of Caring Behaviors Inventory (CBI) among nurses in Iran. Methodology Transcultural translation of the 16-item CBI was performed. Then, face validity (qualitative), content validity (quantitative and qualitative), and construct validity were examined in a cross-sectional study of 509 patients. A demographic questionnaire and the 16-item CBI were sent to enrolled patients via online questionnaires. The reliability of the instrument was assessed by internal consistency using Cronbach’s alpha. Then, construct validity of the single factor CBI was assessed using Confirmatory Factor Analysis (CFA). Since one factor CBI was not confirmed, construct validity was examined using Exploratory Factor Analysis (EFA). The final number of factors was confirmed using CFA. Results The internal consistency of the instrument was good with Cronbach’s alpha 0.89. Based on EFA, the CBI were loaded on two factors, eigenvalues >1, no item was removed. The emergent factors were named "Communicating respectfully" and "Professional knowledge and skill". These two factors explained 50.197% of the total variance. Then, CFA showed an acceptable fit for the two factors CBI. Conclusion The results showed that the Persian version of the 16-item CBI had adequate validity and reliability. Accordingly, this instrument can be used to study nurses’ caring behaviors.

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.

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.
