Abstract
ABSTRACTObjective:to evaluate the validity of the Competence Scale of Actions of Nurses in Emergencies based on internal structure, internal consistency, and external criteria. Methods:methodological study to verify new evidence of validity of the Scale, with contents previously validated. The Scale has 81 measurable actions at five levels of competence and can be applied both for self- and/or hetero-evaluation. Results:one hundred and forty seven nursing assistants and 41 managers from the five regions of Brazil participated in the study. They were linked to mobile prehospital emergency service, fixed prehospital emergency service, or hospital emergencies. Dimensionality was evidenced by exploratory factorial analysis of the 81 items, pointing out seven factors that explained 66.5% of the total data variance. Cronbach’s alpha ranged from 0.79 to 0.98. The Kaiser-Meyer-Olkin 0.988 indicated that the correlations between the items were significant. In the external criterion, Pearson’s correlations between hetero-evaluation competence scores and the manager’s subjective classification were significant (p < 0.001), as well as differences in the means of these competencies by criterion group. In addition, scores by characteristics were evaluated to detect statistically different means. Conclusion:through the adopted Statistical Procedures, with multi-methods and multi-informants, different psychometric properties were analyzed. A summary of evidence was generated showing that the Scale is valid and reliable.
Highlights
In the process of evaluating professional competence, several elements are taken into consideration in the creation of a research tool capable of extracting from the respondents the best response to the alternatives offered
Proposed instrument can be used for self-evaluation of staff nurses, independently of their time working in emergency services, and for evaluation by other professionals, the instrument was tested in a university hospital
Two groups of nurses participated: 407 staff nurses and 41 nurse managers, who worked in 11 hospitals from the five regions of Brazil and in one Ambulatory Medical Care (AMC) unit and one SAMU unit, both located in São Paulo
Summary
In the process of evaluating professional competence, several elements are taken into consideration in the creation of a research tool capable of extracting from the respondents the best response to the alternatives offered. In Psychometrics, the concept of validity can be generically defined as the degree to which theoretical-empirical evidence supports inferences and interpretations about people’s psychological characteristics. This is done based on behaviors observed/measured by a measuring instrument, always considering the relevance and usefulness of the uses proposed in certain contexts(2-5). There are no Brazilian studies published on the creation of technology capable of measuring the professional competence of nurses working in emergencies. As there is no instrument available, it is essential to create one to measure the professional competence of nurses who act in emergencies based on the profile of the professional, the client, the institution and the public policy of the Brazilian emergency care
