BACKGROUND Telemedicine is both effective and can provide efficient care at lower costs. It also enjoys a high acceptance rate among users. The technology acceptance model proposed is based on the two main concepts of ease of use and perceived usefulness and comprises three dimensions: the individual context, the technological context, and the implementation or organizational context. There is not a short validated questionnaire to check the acceptance of telemedicine services amongst health care professionals using a technology acceptance model. OBJECTIVE To translate and validate a telemedicine acceptance questionnaire based in the technology acceptance model. METHODS The study included the following phases: adaptation and translation of the questionnaire into Catalan, and psychometric validation which include construct (exploratory and confirmatory factor analysis), consistency (Cronbach’s alpha) and stability (test-retest). Factor analysis was used to describe variability amongst observed variables. The Kaiser-Meyer-Olkin test of sampling was adequate (KMO = 0.818) and the Bartlett test of sphericity was significant (Chi-square 424.188; gl=28; P < .001), indicating that the items were appropriate for a factor analysis. The final confirmatory factor analysis conducted showed good fit index (RMSEA = 0.102, CFI = 0.93, TLI =0.90; CD =0.96). RESULTS After removing incomplete responses 144 responses where considered for analysis. The internal consistency measured with the Cronbach’s alpha coefficient was good with an alpha coefficient of 0.84 (95%, CI: 0.79-0.84). The intraclass correlation coefficient was 0.93 (95% CI: 0.852-0.964). CONCLUSIONS The questionnaire validated with this study has robust statistical features that potentially make it a good predictive model of professional’s satisfaction with telemedicine programs.

Relevance. Nowadays the researchers commonly use a limited set of standard procedures and statistical coefficients when develop psychometric instruments and investigate their structure. The routine using of such procedures without taking into account the specific features of the psychometric scales can lead to incomplete or even inadequate results. In this context detailed consideration of the structure of psychometric instruments seems to be important and it may demand various non-standard ways of statistical analysis. Objectives. To conduct detailed analysis of the results of two intelligent subtests at the item level and to assess the sufficiency and adequacy of using standard methods for estimation of reliability and structural validity for these subtests. Methods. We analyze the data collected in intelligence testing of a large sample of respondents (11335 young adults). The respondents passed the KR-3 battery. In this study we examine in detail the structure of the subtests “Syllogisms” and “Analogies”. Specifically, we estimated the reliability of the scales by the Cronbach’s alpha coefficient, and the structure at the item level using the confirmatory factor analysis. Results and conclusions. Estimation of the reliability of the scales by Cronbach’s alpha coefficient showed importance of taking into account the time limitation, which is commonly used in intelligence tests. On the other hand, a detailed analysis of each subtest items made it possible to find out an additional factor which was not originally proposed in the factor structure. This is factor of higher-order abilities of abstract analysis, whilst the subtest originally aimed at estimation of the special abilities. Confirmatory factor analysis showed improvement of fit when this factor was added. The results allow to conclude that the researcher may miss the important properties of scales if not making a detailed analysis of testing procedures and the structure of subtest at the item level, and so may draw incomplete or inadequate conclusions about their psychometric properties

Telemedicine is both effective and able to provide efficient care at a lower cost. It also enjoys a high degree of acceptance among users. The Technology Acceptance Model proposed is based on the two main concepts of ease of use and perceived usefulness and is comprised of three dimensions: the individual context, the technological context and the implementation or organizational context. At present, no short, validated questionnaire exists in Catalonia to evaluate the acceptance of telemedicine services amongst healthcare professionals using a technology acceptance model. This article aims to statistically validate the Catalan version of the EU project Health Optimum telemedicine acceptance questionnaire. The study included the following phases: adaptation and translation of the questionnaire into Catalan and psychometric validation with construct (exploratory factor analysis), consistency (Cronbach’s alpha) and stability (test–retest) analysis. After deleting incomplete responses, calculations were made using 33 participants. The internal consistency measured with the Cronbach’s alpha coefficient was good with an alpha coefficient of 0.84 (95%, CI: 0.79–0.84). The intraclass correlation coefficient was 0.93 (95% CI: 0.852–0.964). The Kaiser–Meyer–Olkin test of sampling showed to be adequate (KMO = 0.818) and the Bartlett test of sphericity was significant (Chi-square 424.188; gl = 28; p < 0.001). The questionnaire had two dimensions which accounted for 61.2% of the total variance: quality and technical difficulties relating to telemedicine. The findings of this study suggest that the validated questionnaire has robust statistical features that make it a good predictive model of healthcare professional’s satisfaction with telemedicine programs.

Abstract Background The risk rate for the lifetime prevalence of any mental disorder is calculated as 50%, and the prevalence of mental disorders has an increasing trend. So, this study aimed to evaluate the Mental Health Literacy Scale (MHLS) among Iranian people. Methods This cross-sectional study was conducted with a multi-stage sampling method with 1273 people in the general population. After searching and reviewing various sources, the research team decided to use the questionnaire of MHLS with 35 items and six attributes that were measured and developed by O’Connor et al. The face, content, and construct validity (Confirmatory factor analysis) were used for validation of MHLS. McDonald’s omega coefficient and Cronbach’s alpha coefficient were used to calculate the reliability of MHLS. Confirmatory factor analysis was performed using AMOS software Version 24. Results In the CFA test, the six items were deleted. The final modified version of the MHLS included a total of 29 items with six attributes consisted of (a) knowledge of where to seek information (4 items), (b) ability to recognize disorders (8 items), (c) knowledge of self-treatment (2 items), (d) knowledge of risk factors and causes (2 items), (e) attitudes that promote recognition or appropriate help-seeking behavior (10 items), and (f) knowledge of professional help available (3 items). Based on the results of reliability, McDonald’s omega coefficient and Cronbach’s alpha coefficient for all attributes of MHLS were 0.797 and 0.789, respectively. Conclusion Due to the lack of appropriate instruments for measuring mental health literacy in the Iranian population, the modified version of MHLS with 29 items and six attributes can be considered as a valid and reliable instrument for this purpose.

Abstract Background Effective teamwork is essential for delivering safe health care. It is important to increase patient safety in healthcare by conducting interprofessional team training with both healthcare professionals and undergraduate students. Validated questionnaires that evaluate team training activities contribute to valuable knowledge regarding changes in attitudes toward teamwork. The aim of the study was to test the reliability and structural validity of the Swedish version of the TeamSTEPPS® Teamwork Attitudes Questionnaire (T-TAQ). Methods The study had a cross-sectional design. Four hospitals in three health care regions in Sweden participated in the study. In total, 458 healthcare professionals, response rate 39.4%, completed the questionnaire. The T-TAQ, which consists of 30 items and covers five dimensions (Team Structure, Leadership, Situation Monitoring, Mutual Support and Communication), was translated to Swedish. A paper version of the T-TAQ was distributed to healthcare professionals (physicians, registered nurses, midwives, nursing assistants and allied health professionals) from the hospitals. Reliability and validity were tested using Cronbach’s alpha and confirmatory factor analysis. Results Cronbach’s alpha was 0.70 for the total T-TAQ and ranged from 0.41 to 0.87 for the individual dimensions. The goodness-of-fit indexes in the confirmatory factor analysis (Model 2) revealed a normed chi-square of 2.96, a root mean square error of approximation of 0.068, a Tucker-Lewis index of 0.785 and a comparative fit index of 0.808. Conclusions The Swedish version of the T-TAQ has some potential to measure healthcare professionals’ general attitudes toward the core components of teamwork in hospital settings. Further validation studies of the Swedish version of the T-TAQ are required, with samples representing both healthcare professionals and students from various healthcare disciplines and educational levels.

Objective: To analyze the psychometric properties of the French version of the Weiss Functional Impairment Rating Scale–Self Report (WFIRS-S) in a large clinical sample of adults with ADHD. Method: Patients ( N = 363) were diagnosed with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria. Psychometric properties of the French version of the WFIRS-S were tested including construct validity with a confirmatory factor analysis, internal structural validity with Cronbach’s alpha coefficient, external validity by correlations with the Beck Depression Inventory–II (BDI-II), and the EuroQol five-dimension (EQ-5D) questionnaire. Results: The confirmatory factor analysis found the following: root mean square error of approximation (RMSEA) = 0.061, 90% confidence interval (CI) = [0.058, 0.063]; comparative fit index (CFI) = 0.67. Cronbach’s alpha coefficient was .91. Correlations with EQ-5D descriptive index, visual analogue scale (VAS) scores, and BDI-II scores were –0.48, –0.55, and 0.53, respectively. Conclusion: The French version of the WFIRS-S is a psychometrically acceptable self-reported questionnaire for the multi-domain evaluation of functional impairments in adults with ADHD, for research and clinical purposes.

Background: Substance users are among the most highly stigmatized individuals by both the public and health care providers. However, no multidimensional scale for measuring substance use stigma for substance use disorders (SUDs) currently exists in Turkey. Aims: The aim of this study was to determine the validity and reliability of the Turkish version of the Substance Use Stigma Mechanism Scale (SU-SMS). Method: The study was conducted at the AMATEM (Alcohol and Substance Addiction Treatment Center Clinic). The sample group of this methodological study consisted of 156 participants with SUDs who met the inclusion criteria. “Social-demographics Questionnaire,” “The Substance Use Stigma Mechanism Scale,” and “Internalized Stigma of Mental Illness Scale” were used for data collection. In the validity–reliability analysis of the scale, language and content validity, explanatory and confirmatory factor analysis, criterion-concurrent validity, Cronbach’s alpha coefficient, item–total score correlation, split-half reliability analysis, and test–retest reliability methods were used. Results: Using exploratory factor analysis, it was found that the SU-SMS has five factors. Its five-factor structure was confirmed using confirmatory factor analysis. Its Cronbach’s alpha coefficient was .828, and factor loading was between .402 and .971. Analyses indicated that each of the factors of the Turkish version of the scale had high internal consistency. The test–retest correlation value was .752, p = .000. Conclusions: It was concluded that the Turkish version of the SU-SMS is a reliable and valid instrument for assessing substance use-related stigma in individuals with SUDs.

Abstract Background Limited attention is devoted to the improvement of the quality of life of patients suffering from the negative consequences of Sickle cell disease (SCD). Our study focuses on the evaluation of the performance of the WHOQOL-BREF as a tool to measure the quality of life of SCD Patients in Bahrain. Methods We conducted a cross-sectional study that enrolled 273 SCD patients selected using a simple random sampling technique from primary health-care centers in Bahrain in 2019. A designed questionnaire including the WHOQOL-BREF was filled by the patients during face-to-face interviews in the health centers. The reliability of the WHOQOL-BREF was assessed by standardized Cronbach’s alpha coefficient, and the validity was measured by convergent validity, principal component analysis and confirmatory factor analysis. Results The WHOQOL-BREF had good internal consistency as Cronbach’s alpha coefficient for the overall scale was 0.91. The convergent validity results indicated that the correlation coefficients values for all scale domains are significantly correlated at α < 0.01. Confirmatory factor analysis found that the four-domain structure produced a robust fit to the data. Conclusions The WHOQOL-BREF tool has high internal consistency and validity in assessing the quality of life of Sickle Disease patients in Bahrain.

Objective: Planned for the purpose of determining the validity and reliability of Intercultural Awareness and Intercultural Effectiveness scales, which were developed abroad for measuring the intercultural communication competence of nurses taking care of patients from different cultures. The study is planned as methodological and descriptive.Material and Method: The data were filled by 204 nurses via Nurse Identification Form, Intercultural Awareness Scale and Intercultural Effectiveness Scale. Within the scope of the study, introductory characteristics of nurses were presented with percentiles, mean or median. During the examination of the reliability of Intercultural Awareness and Intercultural Effectiveness scales; internal consistency coefficient was calculated by using the cronbach’s alpha coefficient via test-retest correlation pearson product- moment correlation technique. During the validity examination; confirmatory factor analysis (CFA) was performed for evaluating the construct validity after performing language equivalence and content validity.Findings: In order to provide the language equivalence, the scale was primarily translated into Turkish and then back-translated. After receiving the expert opinion, Content Validity Index (CVI) values of scale items were calculated. Content Validity Index scores were calculated as 3,5 for the Intercultural Awareness Scale and 2,8 for the Intercultural Effectiveness Scale.  Examining reliabilities of the scales; it was determined that the Cronbach’s alpha coefficient was 0.73 for the Intercultural Awareness Scale and 0.85 for the Intercultural Effectiveness Scale, and the test-retest correlation coefficient was 0.89 for the Intercultural Awareness Scale and 0.71 for the Intercultural Effectiveness Scale. In the confirmatory factor analysis of the Intercultural Awareness Scale, the scale is collected under one lower dimension unlike the original scale and consists of totally 9 items like the original scale. Examining the general adhesion coefficients; /sd value 1.64; CFI: 1.00, RMSEA: .019 and SRMR index 0.053. Factor loads vary between .25 and .83. In the confirmatory factor analysis of the Intercultural Effectiveness Scale, the scale has the same number of lower dimensions as the original scale and consists of totally 24 items. Examining the general adhesion coefficients for the Intercultural Effectiveness Scale; /sd value 1.66; CFI: 0.98, RMSEA: .059 and SRMR index 0.077. Factor loads vary between .41 and .85. Items of both scales sufficiently represent their own factor dimensions.Conclusion: Intercultural Awareness Scale and Intercultural Effectiveness Scale are valid and reliable scales. Extended English abstract is in the end of PDF (TURKISH) file. ÖzetAmaç: Farklı kültürlerden gelen hastalara bakım veren hemşirelerin kültürlerarası iletişim yeterliliğini ölçmek amacıyla yurt dışında geliştirilen Kültürlerarası Farkındalık ve Kültürlerarası Etkililik ölçeklerinin güvenirlik ve geçerliğinin belirlenmesi amacıyla metodolojik ve tanımlayıcı olarak planlanmıştır.Gereç ve Yöntem: Veriler Hemşire Tanılama Formu, Kültürlerarası Farkındalık Ölçeği, Kültürlerarası Etkililik Ölçeği ile 204 hemşire tarafından dolduruldu.
