Abstrakt: Background: Training in the use of cost-conscious strategies for medical students may prepare new physicians to deliver health care in a more sustainable way. Recently, a role-modeling cost-conscious behaviors scale (RMCCBS) was developed for assessing students' perceptions of their teachers' attitudes to cost consciousness. We aimed to translate the RMCCBS into Brazilian Portuguese, adapt the scale, transculturally, and validate it.
Methods: We adopted rigorous methodological approaches for translating, transculturally adapting and validating the original scale English version into Brazilian Portuguese. We invited all 400 undergraduate medical students enrolled in the 5th and 6th years of a medical course in Northeast Brazil between January and March 2017 to participate. Of the 400 students, 281 accepted to take part in the study. We analyzed the collected data using the SPSS software version 21 and structural equation modeling (SEM) was performed using AMOS SPSS version 18. We conducted exploratory factor analysis (EFA), varimax rotation, with Kaiser Normalization and Principal Axis Factoring extraction method. We conducted confirmatory factor analysis (CFA), using the SEM. We used the following indexes of adherence of the model: Comparative fit index (CFI), Goodness-of-fit index (GFI) and Tucker-Lewis Index (TLI). We considered the Bayesian Information Criterion (BIC) for Sample-size adjusted. The root mean square error of approximation was calculated. Values below 0.08 were considered acceptable. Composite reliability analyzes were performed to evaluate the accuracy of the instrument. Values above 0.70 were considered satisfactory.
Results: Of the 281 undergraduate medical students, 195 (69.3%) were female. Mean age of participants was 25.0 ± 2.6 years. In the EFA, the KMO was 0.720 and the Bartlett sphericity test was significant (p < 0.001). We conducted the EFA into two factors: role-modeling cost-conscious behaviors in health (seven items) and health waste behaviors (six items). The 13 item-scale was submitted to composite reliability analyzes, obtaining values of 0.813 and 0.761 for the role-modeling cost-conscious behaviors and the health waste behaviors factors, respectively.
Conclusions: We concluded that the cost-conscious behaviors scale has good psychometric properties and is a valid and reliable instrument for evaluating medical students' perception of their teachers' cost-conscious behaviors.
