Background and PurposeThe Breastfeeding Relationship Scale (BFRS) was developed to measure mother–infant mutual responsiveness during breastfeeding. The purpose of this study was to develop and test the psychometric properties of the BFRS.MethodsConstruct validity of a 16-item three-factor model (Mother–Infant Breastfeeding Interaction, Perceived Adequate Milk Supply, and Breastfeeding Synchronicity) was assessed using confirmatory factor analysis (CFA) and reliability (Cronbach’s alpha) across two independent samples.ResultsCFA of the hypothesized three-factor model demonstrated good fit in both samples (comparative fit index > .90, root mean square error of approximation < .06, square root mean residual < .06l). Cronbach’s alpha for the constructs ranged between .73 and .83.ConclusionThe BFRS is a valid measure of breastfeeding relations between mother and infant. Reliability was acceptable for all constructs in both samples.

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.

<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.

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

Purpose: The purpose of this study is to translate the Perceived Therapeutic Efficacy Scale (PTES) into Korean and investigate its validity and reliability. Methods: The authors conducted a cross-sectional survey using baseline data from a randomized controlled study to psychometrically validate the PTES-Korean (PTES-K) among 108 adults with type 2 diabetes from an outpatient clinic at a university-affiliated hospital in Korea. The original PTES was forward-translated and back-translated to ensure translation equivalence of the PTES-K. Structured questionnaires were used for psychometric evaluation; exploratory and confirmatory factor analysis assessed validity, and Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability. Results: The interitem correlation analyses revealed that 5 items were redundant; thus, the scale was reduced to 5 items. A 1-factor model explained 76.85% of the variance; confirmatory factor analysis showed that this model adequately fit the data. The ICC for test-retest reliability was .78; Cronbach’s alpha was .92. The PTES-K showed significant associations with the scores of diabetes self-care activities for physical activity, quality of life, and depressive symptoms. Participants with good glycemic control and regular physical activity tended to have a higher score on the PTES-K than their counterparts, demonstrating known-groups validity. Conclusions: The cross-cultural applicability, reliability, and validity of the PTES-K were confirmed. The PTES-K may be used in clinical settings to examine the potential role of perceived therapeutic efficacy for physical activity in enhanced glycemic control among patients with diabetes.

Patient Enablement

Background: The purpose of our study was to develop and psychometrically test a German-language survey instrument that measures patient enablement generically and in greater detail than previous instruments. Methods: A multidisciplinary team developed 13 items to capture individual aspects of patient enablement (PEN-13). A pre-test with 26 subjects was followed by a random sample survey of N = 1168 subjects. An exploratory factor analysis was conducted in a random split-half sample of the data to explore PEN-13’s factor structure; a confirmatory factor analysis was conducted in the validation sample. The internal consistency of the factors was evaluated using Cronbach’s alpha, PEN-13’s construct validity was checked by means of additional hypothesis testing. Results: The two factors self-management and patient-practitioner interaction, detected in the exploratory analysis, were confirmed with a few modifications in the confirmatory factor analysis, with the comparative fit index (CFI) amounting to 0.903. The Cronbach’s alpha values of those two factors amounted to α = 0.90 and α = 0.82, respectively. The correlations of the PEN-13 score with the ’general self-efficacy’ and ’health literacy’ (HLS-EU-Q16) scores further confirmed its construct validity; the respective correlation coefficients amounted to 0.57 and 0.60. Conclusion: The German version of the survey instrument Patient Enablement Scale—13 items (PEN-13) shows acceptable psychometric properties. Practical implications: PEN-13 seems particularly suitable for health services research purposes. We recommend checking the results in another sample as well as evaluating its responsiveness to enablement-enhancing interventions.

Purpose: Self-transcendence, the ability to expand personal boundaries in multiple ways, has been found to provide well-being. The purpose of this study was to examine the dimensionality of the Norwegian version of the Self-Transcendence Scale, which comprises 15 items. Background: Reed’s empirical nursing theory of self-transcendence provided the theoretical framework; self-transcendence includes an interpersonal, intrapersonal, transpersonal, and temporal dimension. Design: Cross-sectional data were obtained from a sample of 202 cognitively intact elderly patients in 44 Norwegian nursing homes. Results: Exploratory factor analysis revealed two and four internally consistent dimensions of self-transcendence, explaining 35.3% (two factors) and 50.7% (four factors) of the variance, respectively. Confirmatory factor analysis indicated that the hypothesized two- and four-factor models fitted better than the one-factor model (c x2, root mean square error of approximation, standardized root mean square residual, normed fit index, nonnormed fit index, comparative fit index, goodness-of-fit index, and adjusted goodness-of-fit index). Conclusions: The findings indicate self-transcendence as a multifactorial construct; at present, we conclude that the two-factor model might be the most accurate and reasonable measure of self-transcendence. Implications: This research generates insights in the application of the widely used Self-Transcendence Scale by investigating its psychometric properties by applying a confirmatory factor analysis. It also generates new research-questions on the associations between self-transcendence and well-being.

Purpose: The purpose of this study was to assess the psychometric properties of the Barriers or Facilitators to Using Research in Practice (BARRIERS) scale for use in Korea. Methods: A cross-sectional study design was used with 364 nurses working in clinical settings. Item analysis was conducted and convergent and discriminant validity were evaluated using confirmatory factor analysis. Internal consistency reliability was evaluated using Cronbach’s alpha coefficients. Results: Confirmatory factor analysis revealed a 4-factor structure with 25 items that explained 62.9% of the variance. Convergent and discriminant validity were confirmed as examining the factor loading, average variance extracted, and composite reliability. The values of factor loading for 25 items were having higher estimate than criterion and the average variance extracted value for 4 factors ranged from .575 to .667. The Cronbach’s alpha was .90 for the 25 items. Conclusion: The Korean version of the 25-item BARRIERS scale was a reliable and valid scale to measure barriers to research use in Korean health care settings. Based on this psychometric evaluation, research barriers and its associated factors will be investigated using the Korean version of the BARRIERS scale in further study.
