Objective.:
To design and analyze the evidence of content validity, internal structure, and reliability of a questionnaire of preventive practices for hantavirus in an endemic community in the Panamanian context.
Material And Methods.:
Quantitative study of instrumental design. This research was conducted in four phases: Literature review, content validity through expert judgment with the individual aggregate method and the calculation of the V Aiken, pilot test and psychometric validation, through exploratory factor analysis (EFA) and reliability analysis of instrument scores with ordinal alpha.
Results.:
Content validity was evidenced and V Aiken values higher than 0.70 were reported in the lower limit of 95% CI. In the internal structure we identified that the 8 items underlie a single factor that explains 60.70% of the total variance of the test and with factor loadings greater than 0.40; during the reliability analysis, we obtained an ordinal alpha value of 0.84, which is considered good.
Conclusions.:
The Hantavirus preventive practical questionnaire is a brief instrument that shows acceptable psychometric properties to measure the activities or behaviors that people carry out to prevent hantavirus.
