Development and psychometric testing of the Perceived Postoperative Care Competency Scale for Nursing Students: a methodological study.

Introduction: Impulsivity means acting with the least thought towards future behaviors or acting based on thoughts that are not the best option for a person or others. This study was conducted to investigate psychometric properties of the Persian version of the Impulsive Behavior Scale (IBS) of Barratt on pre-hospital personnel of Shiraz University of Medical Sciences in 2023. Materials and Methods: This methodological study was conducted 18 pre-hospital emergency centers of Shiraz University of Medical Sciences during 2022-2023. In this study, the Persian version of the IBS has been used. Face and content validity of the scale in this study was confirmed using qualitative and quantitative methods, and construct validity was confirmed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The reliability of the questionnaire was calculated by Cronbach's alpha and intra-class correlation coefficient (ICC) for each field and the scale. Results: The IBS had three unplanned, motor and attentional subscales with 23 items and the varimax rotation showed variance of 52.06%. In CFA, root mean square error of approximation (RMSEA) was equal to 0.093 and normalized fit index (NFI), comparative fit index (CFI), goodness of fit (GFI) and incremental fit index (IFI) were higher than 0.9. Cronbach's alpha coefficient in the scale was 0.85%, and the intra-subject correlation coefficient (ICC) was 0.84%. Conclusion: The study results showed that the scale for pre-hospital personnel had the required validity and reliability, and it can be used for the impulsive behavior in pre-hospital personnel.

Objectives: One of the fundamental responsibilities of nurses in care is to prevent harm to the patients and others. Many nurses use physical restraints to achieve this goal. Considering that the use of physical restraints in older patients is associated with physical and psychological complications and ethical issues, it is important to identify the nurses’ perceptions of using physical restraint in hospitalized older adults. This study aims to evaluate the psychometric properties of the Persian version of Perception of Physical Restraint Use Questionnaire (PRUQ) to be used in caring for hospitalized older adults in Iran. Methods & Materials: This is a methodological study with a descriptive cross-sectional design that was conducted in hospitals in Kermanshah (Western Iran) in 2019. After obtaining permission from the developers of PRUQ, translation to Persian was performed according to standard protocol of World Health Organization. Then, the Persian version was completed by 330 nurses who were selected by a convenience sampling method based on the inclusion criteria. Then, its face validity and content validity (qualitatively and quantitatively), construct validity using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), test-retest reliability, internal consistency and structural reliability were assessed. Statistical analysis was performed in SPSS v. 23 and AMOS v. 5 applications. Results: Results showed a Content Validity Index (CVR) of 0.78 and a scale CVI of 0.88. Based on the results of EFA and CFA, three factors were extracted including “prevention of fall”, “prevention of interruption or interference in treatment” and “providing safe environment”. The good fit of the three-factor model of the Persian PRUQ was approved based on the model fit indices (Chi square/degree of freedom=2.27, Goodness-of-Fit Index=0.83, Comparative Fit Index =0.91, Normed Fit Index=0.92, Root Mean Square Error of Approximation=0.08). The reliability of the questionnaire was confirmed by Cronbach's alpha coefficient (0.82), structural reliability (>0.70) and intraclass correlation coefficient (0.86). Conclusion: The Persian version of PRUQ has good validity and reliability to be used in nurses working in hospitals in Iran. It can be used in future studies in this population.

COVID-19 infection among pregnant women results in more severe symptoms and higher mortality rates. No comprehensive health literacy for protection against COVID-19 among pregnant women has been available for general use in Thailand. This cross-sectional study aimed to develop and examine an instrument for measuring health literacy of prevention COVID-19 infection among pregnant women (HLS-P). A total of 321 pregnant women aged older than 20 years were participated in this study, Selected through multistage cluster sampling, between September 2021 and January 2022. Data were collected using structured questions that included sociodemographic characteristics and the health literacy scale for protecting against COVID-19 (HLS-P) developed by the researchers. The content and construct validity of the health literacy scale were examined. Exploratory factor analysis performed with principal component analysis and Varimax rotation. Confirmatory factor analysis was conducted using IBM SPSS AMOS 26. The model fitting was evaluated using several indices namely root mean square error of approximation, normed fit index, comparative fit index, and goodness-of-fit index. The reliability of the scale was evaluated using Cronbach's alpha and item total correlation. As a results of exploratory factor analysis of the scale, 31 items were loaded which indicated a 6-factors for the scale that collectively explained 62.59% of total variance. Confirmatory factor analysis also indicated a good fit to the six latent structures with root mean square error of approximation 0.03, normed fit index 0.94, comparative fit index 0.97, and goodness-of-fit index 0.91. Internal consistency reliability was satisfactory with Cronbach's alpha coefficient of 0.94 and the item-total correlation between 0.34 and 0.86. The overall scale was sufficiently reliable. As a result, the HLS-P is a reliable and relevant measure for assessing health literacy in pregnant women. Thus, this scale is profoundly used as an evaluation tool for measuring health literacy among pregnant women, providing critical information for healthcare professionals and policymakers about the health literacy needs and capacity of service receivers.

This study aims to develop a new scale to measure treatment adherence in rheumatic diseases and to measure participants' attitudes towards treatment adherence. The data were obtained using the "treatment adherence scale for rheumatic diseases," which was developed to measure treatment adherence in rheumatic conditions. The research sample comprised 402 patients, and demographic variables were collected. During the scale development process, the Pearson correlation coefficient, Bartlett's test, the Kaiser-Meyer-Olkin value, and exploratory and confirmatory factor analysis methods were used. In confirmatory factor analysis, the validity of the model was evaluated using root mean square error of approximation, non-normed fit index/Tucker-Lewis indices, comparative fit index, normed fit index, and chi-square goodness-of-fit test. In reliability analyses, composite reliability and Cronbach's alpha coefficient were calculated. For descriptive analyses, frequency distributions, measures of dispersion and central tendency, and multiple linear regression analyses were employed. Findings related to the scale development phase: The developed "treatment adherence scale for rheumatic diseases" consists of four factors: behavioral adherence to the treatment process, collaboration and communication with healthcare professionals, medication awareness and consciousness, and medication treatment commitment. The scale comprises 20 items and is scored on a Likert scale. The scale's reliability was 0.92, explaining 55.7% of the total variance. According to confirmatory factor analysis results, the fit indices were found to be χ2/df ratio of 1.99; root mean square error of approximation = 0.07; comparative fit index = 0.99; normed fit index = 0.99; non-normed fit index = 0.99. The multiple linear regression analysis indicated that the model was significant (F = 5.930; p = 0.001) and that approximately 8% of the variation in treatment adherence scores could be explained (R2 = 0.083). The findings reveal that the researchers' treatment adherence scale for rheumatic diseases is a reliable and valid assessment instrument. Using this scale may enhance patient care and treatment management in rheumatic disorders. Furthermore, understanding characteristics that influence treatment adherence might improve treatment efficacy and help lower the total societal burden. Key Points • This study reveals that a newly developed scale for assessing treatment adherence in rheumatic patients is valid and reliable. • The scale offers a thorough assessment by examining patients'' treatment approaches from multiple perspectives, including behavioral, communicative, and drug awareness. • Age and particular individual factors can influence treatment adherence; therefore, customized encouragement and interventions are important..

Science, technology, engineering, mathematics (STEM) education is critical for fostering medical students’ scientific research capabilities, innovative thinking, and interdisciplinary problem-solving skills, which are essential for adapting to technology-driven medical advancement. The aim is to construct a STEM competence assessment scale applicable to students majoring in clinical medicine in medical colleges and universities, and to investigate the current situation of students’ STEM competence through this scale, so as to provide methods and tools for the improvement of STEM teaching in medical education. Through literature review and expert consultation, the dimensions and items of the scale were designed. Exploratory factor analysis, confirmatory factor analysis, root mean square error of approximationOf Approximation and Cronbach α coefficient were adopted to evaluate the reliability and validity of the scale. The finally constructed assessment scale encompasses 4 dimensions, namely knowledge, attitude, behavior and competence, with a total of 45 items in all. The survey results of 1010 students majoring in clinical medicine showed that the Cronbach α coefficient of the scale was 0.933, indicating good internal consistency. Confirmatory factor analysis demonstrated that the model had an excellent fit (χ2/df = 3.646, Root Mean Square Error Of Approximationroot mean square error of approximation = 0.051), and each dimension had relatively high structural validity. The STEM competence assessment scale developed in this research has relatively high reliability and validity, which can effectively reflect the comprehensive performance of medical students in STEM education, and provides an important tool for the evaluation of the effect of STEM education and the improvement of medical education.

This methodological study was conducted to develop a scale to measure communication self-efficacy in nurses and examine its validity and reliability. We selected 54 initial items from literature reviews and interviews with 10 clinical nurses. Thirty-two preliminary items were derived from consultations with 10 experts. To verify the scale's factor structure, we conducted exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) among 469 nurses. Data were analyzed using item analysis, EFA, CFA, discriminant validity, convergent validity, and internal consistency using IBM SPSS Statistics ver. 29.0 (IBM Corp.) and IBM SPSS AMOS ver. 20.0 (IBM Corp.). The scale consisted of 18 items with three factors (ability to apply therapeutic communication skills, crisis management capabilities, and communication competence), which explained 46.1% of the total variance. Convergent validity and discriminant validity were confirmed for the factors. CFA supported the fit of the measurement model comprising three factors (standardized root mean square residual=.04, root mean square error of approximation=.03, goodness of fit index=.92, Tucker-Lewis index=.97, comparative fit index=.98, normed fit index=.89, critical N=216). Internal consistency was confirmed by a Cronbach's α coefficient of .91. The communication self-efficacy scale for nurses is expected to measure communication self-efficacy among nurses. It will be useful for improving nurses' professional communication abilities.

BackgroundOne effective model for studying cigarette smoking cessation is the transtheoretical model (TTM). In order to assess to what degree interventions can make variations in individuals’ behavior, several questionnaires have been developed based on the TTM. This study aims to describe the development of the Persian version of the Decisional Balance Inventory (DBI) for smoking cessation in Iran and to evaluate its psychometric properties.Design and methodsThe forward-backward technique was used to translate the DBI from English into Persian. After linguistic validation and a pilot test among 30 male smoking young adults, a cross-sectional study was performed, and psychometric properties of the Persian version of the DBI were assessed. Using a convenience sampling method, 120 male smokers between 16 and 24 years of age were recruited from three factories in Nowshahr, Iran. In order to assess the reliability of the DBI, internal consistency and test–retest methods were performed. Additionally, face and content validity were assessed, and the construct validity of the DBI was calculated by performing both exploratory and confirmatory factor analysis. Data were analyzed using SPSS and AMOS.ResultsThe mean age of the sample (n = 120) was 20.19 (SD = 2.13) years. The mean scores for the content validity index (CVI) and the content validity ratio (CVR) were .94 and .89, respectively. The results of exploratory factor analysis (EFA) showed a three-factor solution for the DBI that accounted for 55.4% of observed variance. The results achieved from the confirmatory factor analysis (CFA) displayed that the data fit the model: the relative chi-square (×2/df) = 1.733 (p < .001) and the root mean square error of approximation (RMSEA) = .07 (90% CI = .05–.105). All comparative indices of the model including GFI, AGFI, CFI, NNFI, and NFI were more than .80 (.87, .83, .91, .89, and .81, respectively). The Cronbach’s alpha ranged from .78 to .83, indicating an acceptable reliability. Furthermore, the intraclass correlation coefficient (ICC) ranged from .72 to .89, confirming a satisfactory result.ConclusionsThe results from the present study indicate that the Persian version of the DBI has good psychometric properties and is suitable to measure smoking behaviors among Iranian adolescent and young adult smokers. Consequently, the instrument could be used in planning cigarette smoking cessation interventions among Iranian adolescents and young adults.

To test the psychometric characteristics of a five-item Chinese Contraceptive Behavior Scale (CBS) among female adolescents in Taiwan. Improving contraceptive practice is important for reducing adolescent pregnancy. A scale for measuring contraceptive behaviour of sexually active female adolescents will help nurses promote contraceptive practices to sexually active female adolescents. A cross-sectional design. Based on literature review and interview with female adolescents, a five-item CBS was developed. Using convenience sampling, 525 sexually active female adolescents were invited to complete the (anonymous) CBS. Exploratory factor analysis, confirmatory factor analysis (CFA), contrasting group validity and concurrent validity were tested to examine the validity of CBS. A multiple-group analysis was used to test the cross-validation of the structure of CBS in two groups. Cronbach's α and test-retest reliability were used to examine the reliability of CBS. One factor was produced by exploratory factor analysis. Each item significantly loaded on the CBS by CFA. A multiple-group analysis indicated that the structure of CBS was reliable across two different samples. The overall chi-square and model fit indices were χ(2)=13.554, df=8, p=0.094, normed fit index=0.992, comparative fit index=0.994 and root mean square error of approximation=0.036 (90% CI=0.001, 0.069). The scores of CBS significantly correlated with subscales of perceptions of benefits to contraception (r=0.47, p<0.001) and subscales of perceptions of barriers to contraception (r=-0.29, p<0.001). CBS mean scores significantly differed between the participants who used and did not use contraceptives at first sexual intercourse (t=10.00, p<0.001). Cronbach's α for the CBS was 0.81. The intraclass correlation coefficient was 0.94. Conclusions. The CBS had satisfactory validity and reliability. Relevance to clinical practice. Nurses can use CBS to initiate discussions with sexually active female adolescents about their contraceptive practices and provide them with useful strategies to improve their contraceptive practices.

Background:Diabetes self-management questionnaire (DSMQ) is among the relatively new tools with comprehensive structure measuring various dimensions of self-care behaviors in diabetic patients. This study was carried out to evaluate psychometric properties of Persian version of DSMQ.Methods:A cross-sectional study was carried out from January to March 2017 among patients with type 2 diabetes mellitus (T2DM) referred to urban health centers, in Kerman, southeastern Iran. Data were collected from 589 patients using DSMQ. The DSMQ was translated into Persian by forward and backward translation method. Cronbach's alpha method and intraclass correlation coefficient (ICC) were used to measure internal consistency and test-retest reliability, respectively. In addition, construct validity was assessed by confirmatory factor analysis and exploratory factor analysis (EFA).Results:The sum-scale Cronbach's α of DSMQ was equal to 0.82 for 30 participants. The mean inter-item correlation and mean item-total correlation of “Sum Scale” (SS) were equal to 0.21 (standard deviation (SD) = 0.22) and 0.53 (SD = 0.19), respectively. All items had item-total correlations higher than 0.30 except items 7, 11, and 15. For “SS,” ICC was obtained as 0.93. EFA revealed a four-factor model accounting for 62.5% of the total variance. All indices were acceptable for the modified DSMQ with four factors (χ2 = 134.33, degrees of freedom = 89, P = 0.001, comparative fit index = 0.97, root mean square error of approximation = 0.044, Tucker-Lewis index = 0.96, and normal fit index = 0.92).Conclusions:The Persian version of DSMQ was found to have acceptable reliability and validity for assessing self-management among patients with T2DM.

This study aimed to investigate the validity and reliability of the Korean version of the Brief Irritability Test (BITe) and adapt it for Korean patients with psychiatric disorders. A total of 296 patients at the Department of Psychiatry of Hanyang University Guri Hospital completed the BITe, Korean Beck Depression Inventory-II, Korean Beck Anxiety Inventory, the Korean version of the State-Trait Anger Expression Inventory, and Barratt Impulsiveness Scale-11. Construct validity was confirmed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Reliability testing included assessments of internal consistency (Cronbach's α) and item-total correlations. Convergent validity was examined through correlational analyses with variables such as anxiety, depression, anger, and impulsivity. First, the scale had good internal consistency with a Cronbach's α of 0.88. Second, EFA indicated a single dimensionality of the BITe, and CFA demonstrated a reasonable fit for the single-factor model (comparative fit index=0.97, Tucker-Lewis Index=0.95, normed fit index=0.97, goodness-of-fit index=0.96, root mean square error of approximation=0.12, standardized root mean residual=0.03). Finally, the convergent validity analysis revealed a significant positive correlation with depression, anxiety, and anger, except for anger control, which is a sub-variable of anger. The results showed that the Korean version of the BITe had good psychometric properties, and might serve as a valuable tool for assessing irritability in Korean patients with psychiatric disorders.

BackgroundThere are some specific measures for the evaluation of postpartum quality of life, and each have some limitations.ObjectivesThis study investigated the validity and reliability of the Persian version of a postpartum women’s quality of life (PQOL) questionnaire at the eighth week of postpartum.Patients and MethodsThis was a methodological research, and subjects were 500 women, ages 18 - 42, eight weeks postpartum, randomly selected from half of the public centers in Tabriz, Iran, who completed questionnaires in a self-administered manner. Data was collected during a two-month period during 2014 - 2015. A standard forward - backward translation procedure was used to translate the English version of the PQOL into Persian. Content, construct, discriminant, and criterion validity was assessed. The reliability was evaluated by internal consistency and test-retest reliability.ResultsThe PQOL showed good content validity; content validity ratio (CVR) ranged from 0.67 to 1.00 and content validity index (CVI) ranged from 0.78 to 1.00. Construct validity evaluation by exploratory factor analysis (EFA) led to extraction of six factors from the data. Due to the lack of theoretical justification for items’ relocation in the extracted factors and poor-fitting indices obtained by confirmatory factor analysis (CFA), the exploratory model was eliminated, and the original model was presented and incorporated into the CFA, indicating an acceptable fit for the model (root mean square error of approximation [RMSEA] = 0.038 [0.034; 0.042]; comparative fit index [CFI] = 0.90; normed fit index [NFI] = 0.80; non-normed fit index [NNFI] = 0.90; incremental fit index [IFI] = 0.90). The intergroup differences in total and all dimensions of the PQOL, except for social support, indicated the discrimination ability of the questionnaire. The questionnaire indicated a medium correlation with the short form health survey (SF-12) questionnaire (r ≥ 0.50). Cronbach’s alpha coefficient (0.70 - 0.88) indicated a good internal consistency, and the intraclass correlation coefficients (0.87 - 0.92) showed good test - retest reliability.ConclusionsThe findings of this study confirmed the validity and reliability of the Iranian version of the PQOL questionnaire in Iranian women as a specific measure to evaluate the women’s quality of life.

Background: There is a critical need for tools to evaluate the quality of end-of-life care from the perspective of palliative care professionals. Currently, suitable instruments for this purpose are scarce in China. Objective: To translate the Quality of Death and Dying Index (QODDI) into Chinese and assess its reliability and validity among palliative care professionals. Design: A cross-sectional survey was conducted in November 2023 among 1174 health care professionals (doctors, nurses, social workers) in Shanghai, China. Following systematic translation and cultural adaptation, the Chinese QODDI's internal consistency was measured with Cronbach's alpha, and test-retest reliability was assessed with 49 responses over 6 months. Dimensionality was examined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while concurrent validity was assessed using correlations with the Good Death Inventory (GDI). Results: The Chinese QODDI showed high internal consistency (α = 0.979) and moderate test-retest reliability (intraclass correlation coefficient = 0.696, p < 0.001). The EFA revealed a three-factor structure (physical/holistic care, interpersonal support/communication, and informational support). The CFA showed overall good model fit (χ2/df = 4.8, root mean square error of approximation = 0.057, comparative fit index = 0.974, standardized root mean square residual = 0.017, normed fit index = 0.967). Convergent validity was strong, with average variance extracted values for all factors exceeding 0.82. Concurrent validity was supported by significant correlations between QODDI and the GDI (ρ = 0.506, p < 0.001). Conclusions: The Chinese-translated QODDI is a reliable and valid tool for assessing end-of-life care quality in China, with potential applications in research and clinical practice.

There is a lack of an acceptable, reliable, and valid survey instruments to differentiate levels of nursing teamwork on inpatient units in acute care facilities. The aim of this study was to test the psychometric soundness of the Nursing Teamwork Survey (NTS). The survey was administered to 1,758 inpatient nursing staff members using the NTS (return rate = 56.9%), and measures of content, predictive (concurrent), and construct (factorial, contrast, and convergent) validity were completed. Content validity was established by a panel of experts. Concurrent validity showed a significant correlation between teamwork scores and an imbedded question related to overall satisfaction with teamwork (r = .633, p < .001). The exploratory factor analysis on a random half of the sample predicted a 33-item five-factor solution, whereas the confirmatory factor analysis on the remaining half of the sample confirmed the factor structure (comparative fit index = .884, root mean square error of approximation = 0.055, standardized root mean square residual = 0.045). Contrast validity showed that staff in a non-inpatient unit did not answer the questions in the same way (rWG(J) = .25) as the inpatient unit staff (rWG(J) > .90). Convergent validity of the teamwork tool was measured by correlating the Teamwork subscale of the Safety Attitudes Questionnaire with the NTS (r = .76, p < .01). The NTS had good test-retest reliability (r = .92 for overall 33 items; r = .77 to.87 for the five subscales) and internal consistency (alpha = .94 for overall items; alpha = .74 to.85 for the subscales). Aggregation of individual-level responses to the unit level was supported by intraclass correlation coefficient 1 = .16 (p < .001), intraclass correlation coefficient 2 = .9 (p < .001), and mean rWG(J) = .98. The NTS was demonstrated to have good psychometric properties. Further NTS research should include testing the tool in hospitals with varying characteristics and exploring the links to clinical and operational outcomes.
