Psychometric properties of the original and short Hungarian version of the Iowa infant feeding attitude scale

Abstract Background The Iowa Infant Feeding Attitude Scale (IIFAS) is a widely used tool to assess attitudes towards infant feeding. Attitudes towards breastfeeding are one of the main influencing factors of feeding choice and breastfeeding duration. Adaptation of the IIFAS to the Hungarian context provides an opportunity for cross-cultural comparisons and helps to target breastfeeding support interventions. The growing number of shortened scales in various fields of research, demonstrates the necessity to adapt to a changing context of data collection to avoid fatigue and dropout among respondents. However, international comparisons are difficult due to the lack of a consensual shortened form of the scale. The aim of our study was to examine the psychometric properties of the Hungarian version of the IIFAS (IIFAS-H) and propose an 8-item short version that has appropriate construct validity. Methods The original IIFAS was translated into Hungarian and then translated back to English. A cross-sectional study based on an internet survey in 2019 was conducted among 553 mothers whose most recent child’s age was between 6 and 36 months. Psychometric properties of the Hungarian IIFAS were determined and compared with international results. In order to obtain a shorter version of the Hungarian scale, we preferably kept those items that are common with other international abbreviated IIFAS versions and deleted items with a corrected item-total correlation or factor loading of less than 0.3, where factor loadings came from a principal component analysis forcing the extraction of one principal component (factor). Results The 17-item IIFAS-H showed good psychometric properties with a Cronbach’s alpha of0.73. Further analyses proved that the examined three shortened versions of the IIFAS consisting of 11, 9, and 8 items also showed good properties (Cronbach’s alpha = 0.79, 0.79, 0.76, respectively). Conclusions The Hungarian version of the original 17-item long IIFAS proved to be a good measurement tool with good psychometric properties. Based on our analyses, we suggest the use of the 8-item short version (IIFAS-H8) of the scale.

Abstract Background: The Iowa Infant Feeding Attitude Scale (IIFAS) is a widely used tool to assess attitudes toward infant feeding methods. Attitudes toward breastfeeding are one of the main influencing factors of feeding choice and breastfeeding duration. Adaptation of IIFAS to Hungarian provides an opportunity for cross-cultural comparisons and helps targeting breastfeeding support interventions.Methods: The original IIFAS was translated into Hungarian and back-translated to English. A cross-sectional study was conducted among 553 mothers whose latest child’s age was between 6 and 36 months. In addition to the Hungarian IIFAS, infant feeding status and socioeconomic properties were self-reported in the online survey. Psychometric properties, validity and internal consistency were determined and compared with international results.Results: The 17 item IIFAS-H showed good psychometric properties with that of Cronbach alpha=0.733. Further analyses proved that two shortened versions of the IIFAS-17 consisting of 11 and 9 items also showed good properties (Cronbach’s alpha=0.789, 0.787). After comparing our results to the international short versions of IIFAS, we found that they share 8 identical items. These common 8 items have similar good properties with the Cronbach’s alpha=0.763.Conclusions: The benefits of possible use of international comparisons of the 8-item version outweigh its slightly lower reliability compared to the 9 or 11-item versions. Based on our analyses, we suggest the use of the 8-item-long, shortened version (IIFAS-H8) of the scale.

Background Considering the extensive debate that is currently taking place in Spain regarding euthanasia, it is important to examine the attitude of professionals who perform most of their duties at the bedside of these patients and their families. Objectives The aim of the present study was to present an adaptation and validation of the Euthanasia Attitude Scale and to evaluate its psychometric properties among a sample of nursing students in Spain. Research design A cross-sectional study design was conducted. Participants and research context Non-probabilistic sampling was used to recruit 396 Spanish nursing students. Methods A self-report questionnaire, including socio-demographic data and the Euthanasia Attitude Scale, were used for data collection. The psychometric properties of the Euthanasia Attitude Scale were assessed, including reliability and validity. Fit indices of the overall model were computed. Ethical considerations This study was approved by the Hospital Ethical Committee. Students were informed of the aims and procedures and provided written informed consent prior to data collection. Results The factorial solution comprised four domains and the scale demonstrated adequate internal consistency (Cronbach’s alpha = .878). For the exploratory factor analysis, the Kaiser–Meyer–Olkin index of sampling adequacy was .905 and the Bartlett’s Test of Sphericity was 2972.79 (p < .001). The initial factorial solution revealed four factors with eigenvalues of 6.78 for the first factor, 1.90 for the second one, 1.29 for the third, and 1.10 for the fourth factor. Moreover, there was a significant relationship between religiosity and the domains of the Euthanasia Attitude Scale. Discussion This study obtained a Cronbach’s alpha coefficient of .88 which is in consonance with the findings reported by other studies whereby none of the items were removed and the initial structure based on four domains was conserved, with a factorial solution that explains 52.79% of the total variance. The displacement of some items of the domain may be explained by certain religious and/or cultural components as, in accordance with other studies, people with firm religious beliefs are more inclined to refuse euthanasia. Conclusion According to the findings of this study, the Euthanasia Attitude Scale is a reliable and valid instrument to measure the attitudes toward euthanasia in a sample of Spanish nursing students. This Spanish adaptation will be valuable in future studies examining the attitude and implication of nurses, understanding that nurses are key figures in the euthanasia debate.

Abstract Background Patients’ competencies and resources to manage their own health, which is termed health literacy, is a necessity for better health outcomes. Thus, it is relevant to have a comprehensive health literacy measurement tool suitable for populations of interest. The Health Literacy Questionnaire (HLQ) is a tool useful for health literacy assessment covering nine dimensions/scales of health literacy. The HLQ has been translated and validated in diverse contexts but has so far not been assessed in any country in sub-Saharan Africa. We sought to translate this tool into the most common language used in Ghana and assess its validity. Methods We carried out a cross-sectional study using the HLQ concurrently with an assessment of a malaria programme for caregivers with children under 5 years. The HLQ was translated using a systematic translation procedure. We analysed the psychometric properties of the HLQ based on data collected by face-to-face interview of 1234 caregivers. The analysis covered tests on difficulty level of scales, composite reliability, Cronbach’s alpha and confirmatory factor analysis (CFA). Results Cognitive testing showed that some words were ambiguous, which led to minor rewording of the questionnaire. A nine-factor CFA model was fitted to the 44 question items with no cross-loadings or correlated residuals allowed. Given the very restricted nature of the model, the fit was quite satisfactory: χ2 DWLS (866 df) = 17,177.58, p < 0.000, CFI = 0.971, TLI = 0.969, RMSEA = 0.126 and SRMR = 0.107. Composite reliability and Cronbach’s alpha were > 0.65 for all scales except Cronbach’s alpha for scale 9, ‘Understanding health information well enough to know what to do’ (0.57). The mean differences between most demographic groups among health literacy scales were statistically significant. Conclusion The Akan-Twi version of HLQ proved relevant in our description of the health literacy levels among the caregivers in our study. This validated tool will be useful to conduct health literacy needs assessments to guide policies addressing such needs. Further work is needed to validate this tool for use in Ghana and similar contexts.

OBJECTIVES Translate and culturally adapt the short version of Copenhagen Psychosocial Questionnaire II (COPSOQ II) into Brazilian Portuguese (COPSOQ II-Br) and evaluate its psychometric properties. METHODS Translation and cultural adaptation followed the standardized guidelines. Structural validity was assessed using exploratory factorial analysis. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC3,1) and internal consistency by Cronbach’s alpha. Floor and ceiling effect was considered acceptable if less than 15% of participants reported the lowest or highest scores. Measurement error was assessed by standard error of measurement (SEM), while construct validity was tested by correlating the COPSOQ II-Br, the Job Content Questionnaire and the Nordic Musculoskeletal Questionnaire. RESULTS The study evaluated a total of 211 civil servants and service providers in the test and 157 in the retest. After cross-cultural adaptation, the COPSOQ II-Br structure comprised seven domains and 11 dimensions. Most dimensions showed acceptable floor and ceiling effects, excepting “Work family conflicts” (floor effect of 26.1%), and “Meaning and commitment” and “Job satisfaction,” with ceiling floor of 27.5% and 22.3%, respectively. Cronbach’s alpha values reached the recommended levels (varied between 0.70 and 0.87). Test-retest reliability indicated that all dimensions had ICC between 0.71 and 0.81. SEM ranged from 0.6 to 2.2 and the construct validity showed good results with the tested instruments (significant positive and negative correlations). CONCLUSIONS All psychometric properties of the short version COPSOQ II-Br are suitable for use in Brazil. The instrument is thus validated and can be used by occupational health and human resources professionals to evaluate psychosocial working conditions.

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.

Background: The Copenhagen Burnout Inventory (CBI) is a commonly used tool for evaluation of job burnout in three (personal, work-related and client-related) domains. The aims of this study were to translate and investigate the psychometric properties of the Iranian (Persian) CBI. Methods: A total of 750 employees of different occupations (from educational centres, healthcare, industrial settings, and social services) participated in this descriptive methodological study. Aforward-backward procedure was applied and content validity was evaluated by a panel of10 experts. Exploratory and confirmatory factor analyses were used for construct validity. The internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient – ICC), and feasibility (using ceiling and floor effect) were also assessed for this tool. Results: Content validity of the Persian CBI was established. Three-factor structure of the PersianCBI was supported by the factor analysis, and this confirmed the construct validity of the instrument. The internal consistency (Cronbach’s alpha ranged from 0.82 to 0.90) and test-retest reliability (ICC ranged from 0.85 to 0.95) were excellent and there was no ceiling or floor effect. Conclusion: The Persian CBI is a valid and reliable measurement tool for burnout in the Iranian context.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to < 6 (low), 6 to < 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.
