Background The National Institutes of Health Stroke Scale (NIHSS) is a validated tool for assessing the severity of stroke. It has been adapted into several languages; however, a Polish version with large-scale psychometric validation, including repeatability and separate assessments of anterior and posterior stroke, has not been developed. We aimed to adapt and validate a Polish version of the NIHSS (PL-NIHSS) while focusing on the psychometric properties and site of stroke. Methods The study included 225 patients with ischemic stroke (102 anterior and 123 posterior circulation stroke). Four NIHSS-certified researchers estimated stroke severity using the most appropriate scales to assess the psychometric properties (including internal consistency, homogeneity, scalability, and discriminatory power of individual items) and ultimately determine the reliability, repeatability, and validity of the PL-NIHSS. Results The PL-NIHSS achieved Cronbach’s alpha coefficient of 0.6885, which indicates moderate internal consistency and homogeneity. Slightly more than half of the individual items provided sufficient discriminatory power (r > 0.3). A favorable coefficient of repeatability (0.6267; 95% confidence interval: 0.5737–0.6904), narrow limits of inter-rater agreement, and excellent intraclass correlation coefficients or weighted kappa values (> 0.90), demonstrated high reliability of PL-NIHSS. Highly significant correlations with other tools confirmed the validity and predictive value of the PL-NIHSS. In posterior stroke, the PL-NIHSS achieved the required Cronbach’s alpha coefficient (0.71070). Additionally, stroke location did not affect other psychometric features or instrument reliability and validity. Conclusions We developed a valid and reliable tool for assessing stroke severity in Polish-speaking participants. Moderate psychometric features were emphasized without limiting its clinical applications.

Knowledge Scale

<b><i>Introduction:</i></b> Taking into account a progressive increase in the number of individuals affected by dementia and the importance of being knowledgeable about its symptoms, it has become crucial to develop well-validated instruments for measuring knowledge about dementia. The aim of this study was to translate and validate the Frontotemporal Dementia Knowledge Scale (FTDKS) in a Polish population. <b><i>Methods:</i></b> The FTDKS was translated into the Polish language based on the most highly recommended methodological approaches for translating and validating instruments for cross-cultural healthcare research. Psychometric properties were evaluated in a sample of 869 individuals (general population, healthcare professionals, and caregivers) who completed the questionnaire. The reliability of the FTDKS was tested as an internal consistency using both Cronbach’s alpha and McDonald’s omega factor analysis. The convergent and discriminant validity was assessed using the Heterotrait-monotrait Ratio of Correlation between scores of FTDKS, vocabulary intelligence, and Alzheimer’s Disease Knowledge Scale (AKDS). <b><i>Results:</i></b> The results indicate that the scale produces satisfactory psychometric properties (Cronbach’s alpha and McDonald’s omega over 0.80). The internal consistency was slightly higher in the population of healthcare professionals and caregivers than among the general population. <b><i>Discussion:</i></b> The internal consistency of the Polish version of FTDKS demonstrates a similar validity to the original version. The FTDKS can be used to evaluate the effectiveness of educational interventions among caregivers, healthcare professionals, and the general population.

The study aimed to carry on the process of the cultural adaptation of the Italian Spine Youth Quality of Life Questionnaire (ISYQOL) into Polish (ISYQOL-PL). The a priori hypothesis was: the ISYQOL-PL questionnaire is reliable and appropriate for adolescents with a spinal deformity. Fifty-six adolescents (mean age 13.8 ± 1.9) with idiopathic scoliosis (AIS) with a mean Cobb angle 29.1 (±9.7) and two with Scheuermann juvenile kyphosis (SJK) with a kyphosis angle 67.5 (±17.7) degrees were enrolled. All patients had been wearing a corrective TLSO brace for an average duration of 2.3 (±1.8) years. The Institutional Review Board approved the study. The cross-cultural adaptation of the ISYQOL-PL was performed following the guidelines set up by the International Quality of Life Assessment Project. The reliability was assessed using internal consistency (the Cronbach’s alpha coefficient) and test–retest reliability (intraclass correlation coefficient ICC2.1, CI = 95%); moreover, floor and ceiling effects were calculated. The internal consistency was satisfactory (Cronbach’s alpha coefficient 0.8). The test–retest revealed high reliability with the value of ICC2.1 for the entire group 0.90, CI (0.84 to 0.94). There was neither floor nor ceiling effect for the ISYQOL-PL overall score. The ISYQOL-PL is reliable and can be used in adolescents with spinal deformity.

Abstract: Introduction: Clinical teaching is based on a real work environment, in professional practice settings, such as health services and units, under the supervision of the preceptor. Providing medical teachers with an assessment of their teaching skills is a powerful tool for improving clinical learning for students in training. In this context, the EFFECT (Evaluation and Feedback for Effective Clinical Teaching) questionnaire was developed by Dutch researchers in 2012 for teacher evaluation, being validated based on the literature about medical teaching in the workplace and incorporates the skills of the Canadian competency-based medical curriculum. Objective: To translate and cross-culturally adapt into Brazilian Portuguese and to validate the EFFECT questionnaire for teacher evaluation by Medical students. Method: Cross-cultural adaptation with the following steps: initial translation of the English version, synthesis of translated versions, back-translation, creation of a consensual version in Brazilian Portuguese, with adaptation, review, and analysis of content validity by an expert committee, pre-test with retrospective clarification interview, and reliability analysis by factorial analysis and internal consistency test (Cronbach’s alpha coefficient). Result: In the translation and back-translation stages, the disagreements were related to the use of synonyms and none of the items were modified in terms of their understanding, but in terms of adaptation into the Brazilian context. The evaluation of the expert committee showed the versions maintained the semantic and idiomatic equivalences of the content. Eighty-nine students participated in the pre-test. The internal consistency of the EFFECT questionnaire in Brazilian Portuguese was excellent for all domains, with Cronbach’s alpha coefficient ranging from 0.82 to 0.94. Conclusion: The translated and adapted version of the EFFECT questionnaire into Brazilian Portuguese is equivalent to the original instrument and has evidence of high validity and reliability, being able to constitute a national tool to evaluate the efficiency of clinical medicine teaching.

Abstract Introduction. The paper presents the adaptation of the Iowa Satisfaction with Anesthesia Scale to the conditions in Polish hospitals.Methods. The process of cultural adaptation of the Iowa Satisfaction with Anesthesia Scale was divided into three stages. The first stage was to formulate the Polish version of the ISAS. Secondly, the scale was used in the group of patients who were diagnosed with a maxillofacial injury and underwent surgical procedure. The final stage evaluated the psychometric features of the Polish version of the ISAS.Results. 195 questionnaires were completed correctly and they were subject to further analysis. The questionnaires were collected from patients residing at the Maxillofacial Surgery Clinical Ward who were operated under a general anaesthesia due to a maxillofacial trauma. The average result of the satisfaction with anaesthesia in a studied group was 0.77 (scale from -3 to +3) M=2, SD=2.41. The Cronbach’s alpha coefficient calculated for 11 multiple choice questions was 0.598. It would be possible to increase the Cronbach’s alpha coefficient if question no. 1 (I vomited or felt nauseous) was eliminated from the test (maximum 0.601). Every item on the scale had significant influence on the general result (p=0.0001).Conclusions. Polish version of the Iowa Satisfaction with Anesthesia Scale meets the criteria of the psychometric equivalence with the original version. It is necessary to continue research using Polish version of the ISAS to provide a constant verification of reliability and accuracy of the research tool.

Abstract Background The absence of Respectful Maternity Care (RMC) deters mothers from seeking maternity care services. Given the importance of RMC and the lack of a standard tool for its assessment in Iran, the present study was conducted to translate and assess the psychometric properties of the RMC questionnaire in Iranian women. Methods Forward-backward method was used for translating the questionnaire from English into Persian. A total of 265 postpartum women entered the study by simple random sampling from public and private hospitals in Tabriz, Iran. The validity of the questionnaire was confirmed through the face, content and construct validity. Construct validity was assessed through exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were used to confirm the reliability of the questionnaire. Internal consistency was examined by measuring the Cronbach’s alpha in a sample of 20 mothers, and test-retest stability by calculating the Intraclass Correlation Coefficient (ICC) in the same group of mothers, who had completed the questionnaire twice with a two-week interval. Results The exploratory factor analysis led to the extraction of one factor. Item 12 was eliminated due to its low factor loading. X2/df was less than 5, and RMSEA was less than 0.08, which confirms the validity of this model. The Cronbach’s alpha coefficient was obtained as 0.93 and ICC (with 95% confidence interval) as 0.98 (0.96 to 0.99). Conclusion The results of the study demonstrated that the Iranian RMC scale can be used as a valid and reliable instrument to assess RMC in Iran.

Background: Stroke causes a wide variety of clinical manifestations that may have a negative impact on quality of life. Therefore, it is very important to use specific instruments for measuring quality of life in individuals who suffered a stroke. The aim of this study was to develop a psychometrically validated Spanish version of the Newcastle stroke-specific quality of life measure (NEWSQOL). Methods: A psychometric validation of the Spanish version of the NEWSQOL questionnaire was carried out in 159 patients. The reliability (intraclass correlation coefficient and Cronbach’s alpha coefficient), validity (factorial analysis and Spearman’s coefficient), feasibility (response rate), and the ceiling and floor effects were calculated. Results: Internal consistency showed that Cronbach’s alpha coefficient was 0.93. The test–retest reliability was high or excellent for all domains (range 0.71–0.97 p < 0.001). The response rate of the questionnaire was 100% and the average administration time was 20.5 (±7.2) min. No ceiling effect was detected and two domains (pain and vision) may have a significant potential for floor effect. Construct validity showed that all the variables are important enough to keep them all in the questionnaire. Concerning convergent construct validity, a high correlation was found with the Nottingham Health Profile, the Barthel Index, and the Modified Rankin Scale. Conclusion: The Spanish version of the NEWSQOL questionnaire is reliable, valid, and feasible to evaluate quality of life in the Spanish population.

Background: Maintaining dignity is important for successful aging, but there is lack of validated research instruments in the nursing literature to investigate dignity as perceived by the old people. Objective: This is a methodological study aiming to investigate the psychometric properties of the Greek version of Jacelon Attributed Dignity Scale as translated in the Greek language. Research design: A methodological approach consisting of translation, adaptation, and cross-cultural validation. A sample of 188 Greek-speaking old Cypriot persons drawn from the Hospital outpatient departments was asked to complete the Greek versions of Jacelon Attributed Dignity Scale and the Instrumental Activities of Daily Living. Data analyses included internal consistency reliability (Cronbach’s alpha coefficient), item analysis, and exploratory factor analysis using principal component method with orthogonal varimax rotation. Ethical considerations: The study protocol was approved by the National Bioethics committee according to the national legislation. Permission to use the research instrument was granted from the author. Information about the aim and the benefits of the study was included in the information letter. Findings: Cronbach’s alpha for Greek version of Jacelon Attributed Dignity Scale was 0.90. Four factors emerged explaining 65.28% of the total variance, and item to total correlation values ranged from 0.25 to 0.74 indicating high internal consistency and homogeneity. Mean item score in Instrumental Activities of Daily Living was 5.6 (standard deviation = 1.7) for men and 6.7 (standard deviation = 1.7) for women, and the correlations between demographics, Instrumental Activities of Daily Living, and the four factors of the Greek version of Jacelon Attributed Dignity Scale were low; also in multiple linear regression, the values of R2 are presented low. Discussion: Demographic characteristics and degree of functionality seem to be associated with some of the dimensions of dignity but with low correlations; therefore, they cannot predict attributed dignity. Conclusion: The Greek version of Jacelon Attributed Dignity Scale is a valid and reliable tool to measure attributed dignity in Greek-speaking older adults, but further testing of the psychometric properties and other potential factors that may affect the attributed dignity is needed.

Background: Minimal research has examined utility of PC-PTSD-5 in family members of frontline medical workers. The aims of our study were to develop and elucidate the psychometric properties of the Chinese version of the PC-PTSD-5 and to determine its usefulness in screening for possible PTSD in relatives of Chinese healthcare workers during the COVID-19.Methods: We conducted a cross-sectional research in the relatives of medical staffs working in a general hospital during the COVID-19. Descriptive analysis was used to characterize demographic information of family members to find factors associated with PTSD symptoms. For reliability test, the internal consistency of PC-PTSD-5 was accessed using Cronbach's alpha coefficient. A validity test was assessed by Pearson's correlation between scales. A receiver operating characteristic (ROC) curve was used to evaluate the optimal cutoff score with the maximum Youden Index in this study.Results: The result of demographic information indicated that gender and the type of work undertaken by medical staff in the family have a potential impact on the PTSD symptoms of medical staff's family members. Cronbach's alpha coefficient of PC-PTSD-5 was 0.83, indicating the high reliability. Good validity was also demonstrated by Pearson coefficient. By calculating the Youden index, a cutoff score of 2 was found to be optimal in our study, with sensitivity of 80.74% and specificity of 88.43%.Conclusions: Our study has demonstrated the robust psychometric strengths of the PC-PTSD-5, introducing a reliable tool for screening PTSD among vulnerable and neglected families of these medical workers.

Abstract Background: The assessment of sex addiction among different populations requires a valid and reliable tool. Since the Bergen–Yale Sex Addiction Scale (BYSAS) was not available in Iran, this study aimed to evaluate the validity and reliability of the Persian version of BYSAS. Method: After translation/back-translation procedure, a total of 756 Iranian men and women completed the BYSAS. The structural validity of this tool was evaluated by exploratory and confirmatory factor analysis. An expert panel review also examined content validity of the items. Psychometric properties of the scale including validity, reliability (internal consistency [Cronbach’s alpha]) and test-retest) and factor structure were assessed. Results: Content Validity Index (CVI) and Content Validity Ratio (CVR) scores for BYSAS were 0.75 and 0.62, respectively. Data analysis demonstrated satisfactory internal consistency (Cronbach’s alpha ranging from 0.88 to 0.89). Discussion: Study findings suggest that the BYSAS is a valid and reliable instrument for assessing sex addiction among Persian speaking adults. Replication of research findings is needed to expand the BYSAS for clinical and non-clinical Iranian populations.

Background/Objective The purpose of this study was to cross-culturally adapt the Body Perception Questionnaire Short Form (BPQ-SF) into Italian and to assess its psychometric properties in a sample of Italian subjects. Methods A forward-backward method was used for translation. 493 adults were recruited for psychometric analysis. Structural validity was assessed with confirmatory factor analysis and a hypothesis testing approach. Internal consistency was assessed by Cronbach’s alpha and McDonald’s omega. Measurement invariance analysis was applied with an age-matched American sample. Results The single-factor structure fit the awareness subscale (RMSEA = .036, CFI = .983, TLI = .982). Autonomic reactivity (ANSR) was well-described by supra- and sub-diaphragmatic subscales (RMSEA = .041, CFI = .984, TLI = .982). All subscales were positively correlated (r range: .50-.56) and had good internal consistency (McDonald’s Omega range: .86-.92, Cronbach’s alpha range: .88-.91). Measurement invariance analysis for the Awareness model showed significant results (p<0.001) in each step (weak, strong and strict) whereas the ANSR showed significant results (p<0.001) only for the strong and strict steps. Conclusions Our results support the Italian version of the BPQ as having consistent psychometric properties in comparison with other languages.
