| Learning Objective #1: An enhanced understanding of the process involved in validation studies |
| Learning Objective #2: Describe the methodological procedures for cross-cultural validity |
Purpose: To describe the cross-cultural adaptation and psychometric properties of the Attentional Function Index (AFI) into Brazilian culture.
Methods: The AFI, developed by Cimprich (1992), measures perceived effectiveness in purposeful activity requiring attention, through a self-rating scale with 16 items. The process of cultural adaptation was based on a standardized guideline internationally recognized, which involves the following steps: translation of the instrument to the Portuguese language; back-translation, committee review and testing the pre-final version. The final version of the instrument was evaluated by its psychometrics properties: reliability and validity in a sample of 138 undergraduate nurses` student from a public university in the state of São Paulo. The reliability of the instrument was evaluated through the internal consistency and test-retest of the instrument. For the validity, it was used the convergent validity through the Portuguese version of the Profile of Mood States (POMS).
Results: The findings suggested that the translation of the AFI and initial estimates of internal consistency and construct validity were adequate. The data resulted in high internal consistency score with a Crombach`s alpha reliability of 0.89 and the intraclass correlation coefficient for test-retest reliability was 0.81. In relation to the validity of the instrument, it resulted in one moderate negative correlation (r= -0.64, p< .0001) for convergent validity with the POMS.
Conclusions: The results indicated that the cross cultural adaptation process were satisfactory, demonstrating that the Brazilian version of the attentional function index can be used to measure the person` perception of effectiveness in activities requiring direct attention. Further psychometric testing of the Brazilian version of the AFI with other populations is recommended.
