Turkish Validity–Reliability of Breast Cancer Beliefs Scale and the Effect of Socio-Demographic Factors on Breast Cancer Beliefs

Background and Objective. The Moore Index of Nutrition Self-Care (MIN-SC) questionnaire has been used widely in both English and Spanish languages. The purpose of this study is to convert MIN-SC into the Arabic language and to test the translated tool for validity and reliability among adolescents in Saudi Arabia. Method. The psychometric characteristics of MIN-SC were assessed using college freshman students at King Saud University in Riyadh, Saudi Arabia. The validity and reliability were examined using Cronbach’s alpha coefficient. The construct validity was examined through principal component analysis. Results. The MIN-SC instrument was shown to be internally consistent with reliable scoring (Cronbach’s alpha = 0.910). Exploratory factor analysis resulted in 42 items loading on three main components: estimative, production, and transitional, with a factor loading of eigenvalues >2. The final model explained 38% of the variance. Conclusion. The Arabic version of MIN-SC was shown to be a valid and reliable tool for assessing attitude toward nutrition among adolescent students.

Abstract: Introduction: Motivation contributes greatly to learning, being a predictor of student performance. Thus, instruments that assess motivation after exposure to different teaching strategies and materials can contribute to the analysis and decision on its effectiveness. In this sense, the Instructional Materials Motivation Survey (IMMS) instrument measures students’ motivation after instructional activities. Objective: This study aimed to evaluate the evidence of validity of the IMMS, previously translated and cross-culturally adapted to Brazilian Portuguese. Method: Cross-sectional study used to evaluate the psychometric properties of the IMMS questionnaire, applied to 211 students from the first, third and fourth semesters of the medical course at José do Rosário Vellano University (Unifenas - Campus Belo Horizonte). The principal component analysis (PCA) with Varimax rotation and Cronbach’s alpha coefficient were used to assess the validity and reliability of the instrument. Results: The PCA reduced the instrument’s items from 36 to 25 items, distributed in four dimensions. The saturation of the items in the dimensions ranged from 0.529 to 0.790 and the total explained variance was 63.12%. The reliability of the modified IMMS (IMMS-BRV), measured by Cronbach’s alpha, ranged from 0.76 (Attention dimension) to 0.93 (Interest dimension). Conclusion: The IMMS application in the remote education scenario, through asynchronous video lectures of human anatomy, resulted in an alternative instrument (IMMS-BRV), with fewer items (more parsimonious) and good internal consistency, demonstrating preliminary evidence of its validity and reliability adequacy.

Objectives: This study was designed to investigate the role of cultural beliefs on weaning. Therefore, the obtained results can be used for health policymakers who design strategies to prevent physical and mental damage to mothers and their children. The main objective of this study was to design a questionnaire probing the role of cultural beliefs on weaning. Materials and Methods: The sequential combination exploratory mixed methods design was used to develop the questionnaire format in two sections. The qualitative section was designed to probe the role of cultural beliefs on weaning, which included a literature and related tools review and fieldwork (semi-structured interviews with mothers). Twenty-two studies were examined in the literature review and 14 mothers were selected and interviewed by a purposive sampling technique. The interviews continued up to data saturation as well. In addition, data analyses for both steps were conducted using conventional and textual content analyses. The quantitative section was a methodology study that was accomplished in two parts. Questionnaire items were formed using the data and item pool obtained from the first part. Finally, the psychometric properties of the questionnaire were checked using face, content, and construct validity, followed by probing reliability using Cronbach’s alpha reliability in the second part. Results: Qualitative data analysis results were organized according to the foundational issues regarding the need for weaning, attitude toward weaning, awareness about weaning, society’s culture, health literacy, self-action, others’ experiences, professional help, family members’ support, and the outcomes. The item pool was formed using literature reviews and interviews. A 49-item questionnaire was developed after the completion of the psychometric process. The Kaiser-Meyer-Olkin Index of Sampling Adequacy and Bartlett’s test of sphericity showed good results in this regard. Five components from the exploratory content analysis encompassing contexts, solutions, searching for help, maternal outcomes, and child-related outcomes demonstrated a 62.112% variance. Further, the Cronbach’s alpha was 0.88 and the interclass correlation coefficient was 0.89 based on responses to the items over two administrations of the questionnaire (P < 0.001). Thus, these results showed a high level of tool stability. Conclusions: For this study, a questionnaire was developed for understanding the role of cultural beliefs on weaning. It can be used for educational, research, and treatment purposes as a tool with appropriate validity and reliability, as well as short, easy, and grammatically simple items. Eventually, the questionnaire is useful for examining mothers’ false beliefs about weaning and their educational needs since false beliefs could cause destructive and health-threatening behaviors.

Abstract Background A blended learning environment is multifaceted and widely used in medical education. However, there is no validated instrument for exploring students’ learning in a blended learning environment in medical programs. This study aimed to develop and validate an instrument for exploring how medical students learn in an undergraduate medical program that employs a blended learning approach. Method Using Artino’s seven step approach, we developed a questionnaire to investigate how medical students learn in a blended learning environment. For pilot testing, 120 students completed this 19-item questionnaire. These 19-items were evaluated for construct and convergent validity across an expert medical education panel. Further item testing was analysed with principal component analysis (PCA) with varimax rotation for item reduction and factor estimation. Hence, validity was thoroughly addressed to ensure the questionnaire was representative of the key focus questions. Cronbach’s Alpha was used for item reliability testing, and Spearman’s Rho was used for the correlation between the questionnaire items and the extensively used MSLQ. Hence, validity and reliability were systematically addressed. Results Exploratory Factor analysis identified four factors F1 and F3: Resources: Accessibility & Guidance (14-items), F2: Learning behaviours: Social and Contextual (5-items), and F4: Motivational factors: Intrinsic and Extrinsic Motivation (4-items). Internal consistency and reliability tests were satisfactory (Cronbach’s Alpha ranged from 0.764 to 0.770). Conclusions The resulting Blended Learning Questionnaire (BLQ) was determined to be a reliable instrument to explore undergraduate medical students’ learning in a blended learning environment.

Background: Hope is essential for patients with acute myocardial infarction, which is often regarded as an active coping for those with life-threatening diseases. Higher hope consistently is related to better health outcomes. However, the instrument for assessing hope has not been previously tested among Thai patients. Objective: This study aimed to assess the validity and reliability of the Hope Scale among Thai patients with acute myocardial infarction patients. Methods: This was an instrument validation study conducted from March to December 2020. A total of 213 patients with acute myocardial infarction were included and selected using a simple random sampling. The back-translation method was used to translate an English version to a Thai version of the scale. Principal Component Analysis (PCA) and Cronbach’s alpha were used for construct validity and reliability. Results: The findings showed that the Cronbach’s alpha of the Thai version of the Hope Scale was acceptable (.75), and the scale consists of four factors, which explained 63.36 % of the total variance. Communalities in each factor ranged from .45 to .84. Overall, the appearance of the factor structures was reasonable and understandable. Conclusion: The reliability and validity of the Thai version of the Hope Scale were suitable for the measurement of hope in Thai patients. This scale can be used by nurses and others to assess hope in Thai patients with acute myocardial infarction. Funding: This study received funding from the 90th anniversary of Chulalongkorn University Fund (Ratchadaphiseksomphot Endowment Fund), Chulalongkorn University, Bangkok, Thailand (GCUGR1125633058M).

The objective of this study was to evaluate the construct validity and reliability of the Healthy Eating Food Index-2019 (HEFI-2019), which was developed to measure adherence to Canada’s Food Guide 2019 (CFG) recommendations on healthy food choices. Dietary intake data from 24-hour dietary recalls in the 2015 Canadian Community Health Survey - Nutrition were used for that purpose. Multidimensionality was examined using principal component analysis. Mean scores were compared among subgroups of the population. The association between scores and energy intake was assessed using Pearson correlations. Cronbach’s alpha was calculated to assess reliability. The estimated mean HEFI-2019 score (/80) was 43.1 (95%CI, 42.7 to 43.6) among Canadians 2 years and older. The first and 99th percentiles were 22.1 and 62.9 points. The mean HEFI-2019 score for smokers was 7.1 points lower than for non-smokers (95%CI, -8.4 to -5.8). The HEFI-2019 was weakly correlated with energy intake (r=-0.13; 95%CI, -0.20 to -0.06). The principal components analysis revealed at least 4 dimensions. Cronbach’s alpha was 0.66 (95%CI, 0.63 to 0.69). Evidence of construct validity and internal consistency support the use of the HEFI-2019 to assess adherence to CFG-2019’s recommendations on healthy food choices. Novelty: • Examination of the Health Eating Food Index (HEFI)-2019’s psychometric properties is needed prior to implementation • Analyses support the construct validity and internal consistency of the HEFI-2019 • Interpretation of the total HEFI-2019 score must be accompanied by its components’ scores, considering it assesses multiple dimensions of food choices

Abstract Background: Behavioral Activation (BA) is an evidence-based treatment that aims to help the individual to stay active and reduce avoidance behaviors, as a means to reduce depressive symptoms. This study aims to describe the adaptation process and evaluate the psychometric properties of the Behavioral Activation for Depression Scale Short Form (BADS-SF) in its Brazilian and Peruvian version.Methods: Data were collected as part of a randomized trial with 880 participants in Brazil and 432 in Peru. The content validity was assessed using the Content Validity Index (CVI). Principal Component Analysis (PCA) method was applied to evaluate the factorial distribution. Sampling adequacy was assessed by Bartlett’s test of Sphericity and Kaiser-Meyer-Olkin measure. Cronbach’s alpha coefficient was calculated to assess internal consistency.Results: CVI in Brazil was 0.92 and in Peru 0.87. The two-factor solution of the original scale is sustained (activation and avoidance), accounting for 50.6 and 54% of the total variance in Brazil and Peru, respectively. Cronbach’s alpha in Brazil was 0.55 and 0.66 in Peru for the overall scale. KMO was 0.769 and 0.790 for Brazil and Peru, respectively. Bartlett’s test of Sphericity had significance of 0.000 for both samples. Conclusion: Both studied versions of the BAD-SF showed coherent structure and internal consistency. We recommend different distribution of the items into the subscales.

Introduction: Women's screening beliefs play an important role in their performance. Since a short form questionnaire is necessary in the assessment of screening beliefs in Iranian society, this study was conducted with the aim of psychometric evaluation of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) among Iranian women. Methods: In this cross-sectional methodological study, 300 Iranian women who were aged 18 years or older, and who were attending healthcare centers of Shahid Beheshti University of Medical Sciences, were selected in 2017-18. After a backward-forward translation procedure of BCSBQ was carried out, the face, content and construct validity of breast cancer-screening beliefs questionnaire were evaluated. In addition, the reliability was measured using the Cronbach's alpha and intra class correlation coefficients. Results: The results of the exploratory and confirmatory factor analysis were used to extract three distinct factors, including: attitude, knowledge, and barriers to screening. The three-factor model fit was accepted for all factors based on standard indices (RMSEA = 0.12, χ2 = 2.832, GFI = 0.87, AGFI = 0.8, CFI = 0.94, NFI = 0.92). In addition, the instrument’s reliability was measured using the Cronbach's alpha coefficient. The instrument had an appropriate Cronbach alpha (0.78). The interclass correlation coefficient was obtained to be 0.93 within a range of 0.83-0.97. Conclusion: The three-factor structure of the BCSBQ-12 had appropriate validity and reliability among Iranian women. Considering its appropriate psychometric properties, this instrument can be employed in subsequent studies to measure women's breast cancer screening beliefs in Iran.
