Construct validity and reliability of the BARRIERS scale in the Spanish context.

OBJECTIVE: To establish the construct validity of the Spanish version of the BARRIERS scale. METHOD: Methodological study of validation of a measurement instrument based on data from previously published studies. The study population consisted of nurses from the Basque Health Service and the Canary Health Service. The following variables were extracted and unified: Years of professional experience, possession of a specialist nursing degree, possession of a doctorate, type of activity performed by the professional and field of work. For construct validation, a confirmatory factor analysis (CFA) was performed based on the initial model proposed for the scale and RASCH analysis. A polychoric correlation matrix, factor extraction by unweighted least squares and PROMIN oblique rotation were used. For the RASCH analysis, the Joint Maximun Likelihood estimation (JMLE) method was used; the fit of the items and persons were estimated by means of outfit - Unweighted Mean Square fit statistic (UMS) and infit -Weighted Mean Square Fit Statistic (WMS), as well as the reliability and separation of items and persons. RESULTS: A total of 1200 nurses and midwives made up the final validation sample (n = 1200), with a mean professional experience of 21.22 ± 9.26 years. The CFA presented a good fit to the data (KMO = 0.935 [95% CI: 0.921-0.945]), changing the factorial assignment in 6 items, while 5 items received factorial scores in more than one factor. The fit values for the 4-factor solution were RMSEA = 0.026 [95% CI: 0.026-0.027] and GFI = 0.991 [95% CI: 0.986-0.991]. In the RASCH analysis most items presented infit-WMS and outfit-UMS values with a good fit. CONCLUSIONS: The Spanish version of the BARRIERS scale has adequate construct validity although there are changes in the assignment of items to the dimensions compared to the original model. The RASCH analysis indicates adequate fit for both persons and items.

Attitudes, capacities and perceived barriers in research of nurses of the Canary Health Service.

OBJECTIVE: To evaluate the attitudes, capacities and perceived barriers associated with research among nurses and midwives of the Canary Health Service (SCS). METHODS: Descriptive observational cross-sectional study with an analytical component carried out in the different SCS departments by means of an online survey in which sociodemographic and specific variables, the Spanish version of the Attitudes towards Research and Development within Nursing Questionnaire (ATRDNQ-e) instrument and the BARRIERS scale were collected. Authorisation was obtained from the two provincial ethics committees. A descriptive and inferential analysis (Mann-Whitney U test and Kruskal-Wallis test, post hoc contrast by Dwass-Steel-Critchlow-Fligne test) was performed with JAMOVI® v.2.3.24 software. RESULTS: A total of 512 nurses and midwives with a mean age of 41.82 years participated in the study. Regarding the scores with the ATRDNQ-e instrument, the dimension with the lowest score was «Language of research¼ (mean = 3.55/SD = 0.84) and the highest «Assessment of nursing research and development of the nursing discipline¼ (mean = 4.54/SD = 0.52). The total mean score with the BARRIERS scale was 54.33 (SD = 16.52), with «Organizational characteristics¼ being the highest scoring subscale (mean = 17.25/SD = 5.90). The two highest perceived barriers were «Not enough time at work to implement new ideas¼ (mean = 2.55/SD = 1.11) and «Nursing does not have time to read research¼ (mean = 2.46/ SD = 1.11). CONCLUSIONS: SCS nurses have a positive attitude towards research, although there are some barriers where improvement actions for nursing research should be implemented.
