Breast Cancer Related Lymphedema

The purpose of study was to develop the Breast Cancer Related Lymphedema Self-Care Scale to evaluate the self-care practices of women with breast cancer-related lymphedema (BRCL); and to examine the psycholinguistic and psychometric characteristics of this scale. The item pool of the scale was created based on the literature in this descriptive study. Content validity, explanatory and confirmatory factor analyses used in evaluation of the validity; and item analyzes, the Cronbach’s Alpha and Split Half analyzes were made for reliability in the study. The content validity index was found to be above 0.80. In the Explanatory Factor Analysis, a four-factor structure was obtained. In Confirmatory Factor Analysis, fit indices were found to be acceptable. Cronbach’s Alpha coefficients of the sub-dimensions of the scale varied between 0.62 and 0.86. It was determined the Breast Cancer Related Lymphedema Self-Care Scale was a valid and reliable scale for women with BRCL.

The purpose of this study was to evaluate the psychometric properties of the Brazilian Scale for the Assessment of Self-Care Behaviors with Arteriovenous Fistula in Hemodialysis. Cross-sectional validation study, followed the recommendation provided by Sousa and Rojjanasrirat. Content validity, explanatory and confirmatory factor analyses used to check validity and Cronbach’s alpha was the reliability measure. Three hundred hemodialysis patients with arteriovenous fistula were included in the study. The expert committee assessed the content validity. Exploratory factor analysis confirmed the same two-factor structure found for the original scale, explaining 60.10% of the variance. Such solution was checked by confirmatory factor analysis with Cronbach’s alpha equal to 0.920, 0.810, and 0.884 for the overall scale, the self-care in management of signs and symptoms and the self-care in prevention of complications subscales respectively. The scale has good psychometric properties to assess self-care behaviors and can be used with Brazilian patients on hemodialysis with arteriovenous fistula.

<b><i>Background:</i></b> The incidence of dementia is increasing dramatically worldwide. It is important to determine knowledge about the dementia for it’s prevention, early diagnosis, treatment, and care. The psychometric properties of the Turkish version of the Dementia Knowledge Assessment Scale (DKAS-T) were evaluated in this study. <b><i>Methods:</i></b> The psychometric study was conducted. A total of 1592 participants were recruited between November 2019 and March 2020. The data were collected using a sociodemographic form and DKAS-T. The language and content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were used to assess the validity of the scale. The scale’s reliability was obtained using Cronbach’s alpha coefficient, a paired sample <i>t</i>-test, item-total score correlation, and Hotelling’s <i>T</i>-squared test. <b><i>Results:</i></b> The mean age of the sample was 29.38 (±11.50) years; 66.8% (<i>n</i> = 1064) were female, and 54.1% (<i>n</i> = 861) reported their income status as income equal to expenditure. The DKAS-T demonstrated content validity and adequate sensitivity (Kendall <i>W</i> = 0.155, <i>p</i> = 0.093). The scale consisted of seventeen items and was unidimensional, which explained 28.705% of the variance. All the factor loadings were found to be &#x3e;0.30 in factor analysis. In CFA, all of the fit indexes were &#x3e;0.95 and root mean square error of approximation (RMSEA) was 0.033. A Cronbach’s alpha value of 0.836 was obtained for the entire scale. It was determined that the scale has invariance according to time (<i>t</i> = −1.362, <i>p</i> = 0.181). Homogeneity of the scale was 3.26%, and there was no absence of reaction bias (Hotelling’s <i>T</i>-squared = 2573.681, <i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> The results demonstrated that the instrument is reliable and generates valid data for the Turkish sample. This scale can be used to determine knowledge about dementia and planning educational interventions in the issue.

Duke Health Profile

Background: Duke health profile (DHP) is a 17-item questionnaire that measures six health scales (physical, mental, social, general, perceptual, and self-confidence) and four dysfunction scales of anxiety, depression, pain, and disability. Objectives: To systematically translate DHP to Persian language and measure the validity and reliability of the translated version. Methods: We used the forward-backward method for translation of DHP from English to Persian. After linguistic matching and pilot review, a cross-sectional study was carried out on 239 individuals aged over 18 to measure the psychometric characteristics of the Persian version of DHP. The reliability of the questionnaire was assessed using Cronbach’s alpha and test-retest analysis. Content validity, face validity, and construct validity were evaluated by an expert panel, interviewing a sample of the general population, and confirmatory factor analysis, respectively. Results: Item content validity indexes (I-CVI) for relevance and clarity were between 88 and 100. Scale content validity index (S-CVI) for relevance and clarity were 96% and 94%, respectively. The calculated item content validity ratio (I-CVR) was between 0.78 and 1.0. The confirmatory factor analysis showed that the data fit the model, and the indicators of fitness were acceptable. The Cronbach’s alpha was 0.77 for the total tool and varied between 0.47 and 0.69 for different subscales. The reliability of the test-retest was 0.64 - 0.88, which was good after two weeks. Conclusions: The Persian version of DHP is a valid and reliable tool for measuring health profile.

Abstract Background There are major changes in education strategies as higher education institutions urgently need to adopt distance education tools and practices due to the Covid-19 pandemic. Medical education is also trying to get out of this emergency using distance education. In this study, we aimed to develop a reliable and valid scale in order to evaluate the perceptions of medical students towards distance education. Methods The students taking part in the study were in the first five academic years of the medical faculty in Bursa in Turkey. At first, 57 items were determined to evaluate students’ perceptions. Content validity was examined according to the assessment of the expert team. Construct validity of these items was examined by exploratory and confirmatory factor analysis. Also, Cronbach’s alpha coefficients were calculated for reliability analysis. The medical students’ responses were scored using a five-point Likert scale. Results When the content validity was examined, the number of items was determined to be 38 items. Construct validity of these items was examined by exploratory and confirmatory factor analysis. Because of the exploratory factor analysis performed on the responses of 429 medical students, 22 items were included in four factors. This four-factor model was applied to 286 medical students and validated by confirmatory factor analysis. Also, Cronbach’s alpha coefficients were calculated for reliability analysis and values were between 0.713 and 0.930. Conclusions This study demonstrated validation and reliability of perceptions of distance education for medical students. We suggest a 22-item model with a four-factorial scale.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.

Abstract Purpose The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. Methods AQoL-8D was translated into Polish. 463 patients (age18–80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach’s alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. Results The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker–Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] Conclusion AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

Breastfeeding Attitudes

Positive attitudes towards breastfeeding in health professionals/students have been associated with increasing their confidence to provide support and accompaniment to mothers. In Mexico, there is no valid/reliable tool to assess attitudes towards breastfeeding in this population. The Australian Breastfeeding Attitudes (and Knowledge) Questionnaire (ABAQ) measures attitudes in the Australian population. We aimed to adapt and validate the ABAQ in Mexican health students. We included 264 health students (nursing, nutrition, and medicine) from the University of Guadalajara. Bilingual translators carried out the Spanish adaptation with a reverse translation into English. Experts evaluated the content validity. Reliability was evaluated through an internal consistency analysis (Cronbach’s alpha) and construct validity through convergent–divergent validation, item–total correlation, exploratory factor analysis (by principal components), and confirmatory factor analysis. According to the exploratory factor analysis, only one component was identified. Seven items were removed (low correlation between items ≤0.2 and low factor load ≤0.3). The Cronbach’s alpha was 0.78. According to the confirmatory factor analysis, the one-factor solution of the ABAQ-13Mx showed a good model fit (X2 = 98.41, G = 62, p = 0.02, CFI = 0.940, and RMSEA = 0.048). The ABAQ-13Mx is a reliable and valid instrument for evaluating attitudes towards breastfeeding in Mexican health degree students.

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

Abstract BACKGROUND: This study aimed to translate and validate the Motivation to Change Lifestyle and Health Behaviours for Dementia Risk Reduction (MCLHB-DRR) scale in the Dutch general population.METHODS: A random sample of Dutch residents aged between 30 and 80 years old were invited to complete an online questionnaire including the translated MCLHB-DRR scale. Exploratory and confirmatory factor analyses (EFA and CFA) were conducted to assess construct validity. Cronbach’s alpha was calculated to assess internal consistency.RESULTS: 618 participants completed the questionnaire. EFA and Cronbach’s alpha showed that four items were candidate for deletion. CFA confirmed that deleting these items led to an excellent fit (RMSEA = 0.043, CFI = 0.960, TLI = 0.951, χ²/df = 2.130). Cronbach’s alpha ranged from 0.69 to 0.93, indicating good internal consistency.CONCLUSION: The current study demonstrated that the Dutch MCLHB-DRR scale is a valid scale for assessing health beliefs and attitudes towards dementia risk reduction among Dutch adults aged between 30 and 80 years old.
