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.

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.

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.

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: 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.

Background: Diagnostic questionnaires play a great role in accelerating the diagnosis of mental disorders. Objectives: This study aimed to provide a cross-cultural adaption form of Self-report oppositional defiant behavior inventory (SR-ODBI) in Persian and assess the validity and reliability of this Persian form. Methods: The present study was done on two research samples, including a sample of 294 students who were selected in the school year of 2019 - 2020 (girls and boys) from high schools of Dezful city by multi-stage random sampling method and a sample of 320 parents. The validity of the oppositional defiant behavior inventory was assessed by two methods of confirmatory factor analysis and convergent validity, and the reliability of the inventory was assessed using Cronbach's alpha and split-half methods. Results: Cronbach's alpha was obtained at 0.73 (0.87) for the whole self-report scale (parent version), 0.72 (0.74) for the subscale of irritability, and 0.81 (0.80) for the subscale of stubborn and resentful behavior. The correlation between SR-ODBI and Achenbach Youth Mental Health Test was 0.56 (P < 0.01). The results of confirmatory factor analysis (RMSEA = 0.06 and 0.08) also indicated a relatively good fit of structures of the oppositional defiant behavior inventory. Conclusions: The results of the research indicated that the Persian version of the Oppositional Defiant Behavior Inventory in Iran has good reliability and validity.

Abstract Background: The Family Crisis Oriented Personal Evaluation Scales (F-COPES) is a widely used instrument to evaluate family coping behaviours. However, no Chinese version of this scale have been developed and validated in China. This study aimed to develop a Chinese version of the F-COPES and evaluate its psychometric properties in the families of patients with dementia who have heavy stress and care burdens.Methods: A cross-sectional study in the specialist memory and geriatric psychiatric clinics of four hospitals in Beijing, China. The English version of the F-COPES was translated into Chinese according to the standard translation guideline. An expert panel was invited to evaluate the content validity index of the Chinese version of this scale. This study included 215 families of patients with dementia. The item homogeneity analysis was conducted by using corrected item-total correlation, corrected item-subscale correlation, and changes of Cronbach’s alpha coefficient of subscales after deleting each item. The factor structure was analysed by using a confirmatory factor analysis. The convergent validity was tested by correlating the F-COPES to the Multidimensional Scale of Perceived Social Support (MSPSS). The internal consistency was assessed by using Cronbach's alpha coefficients of the whole scale and subscales.Results: The content validity index of the Chinese version of the F-COPES was 0.98, with that of each item ranging from 0.83 to 1.00. The result of item homogeneity analysis was satisfactory except for the items in the subscale of passive appraisal. The confirmatory factor analysis identified six subscales; namely, acquiring relatives’ support, acquiring friends’ support, acquiring neighbours’ or others’ support, reframing, seeking spiritual support, and passive appraisal, with acceptable model fit indices (χ2/df = 1.65, CFI = 0.91, GFI = 0.85, TLI = 0.90, PGFI = 0.69, RMSEA = 0.06). The convergent correlation between the F-COPES and the MSPSS was strong (r = 0.50, P < 0.01). The Cronbach's alpha coefficients of the whole scale was 0.86.Conclusion: The Chinese version of the F-COPES showed satisfactory psychometric properties. It may serve as a useful scale for assessing the coping behaviours in families of patients with dementia in China.
