Evidences of validity based on the internal structure and the relations with other variables for the brazilian adaptation of the Index of Premature Ejaculation

The present research has studied the validity evidences for the Brazilian adaptation of the Index of Premature Ejaculation (IPE). The IPE is a self-report questionnaire which content of 10 items evaluating the Premature Ejaculation (PE) in the dimensions: sexual satisfaction, ejaculatory control and distress. Therefore, it has been recruited; 163 men whose ages were between 18 and 58 years old. The applications in the samples occurred at different times with the fulfillment of the ethical criteria required in the research. The factor analysis by the main components with varimax rotation extracted 3 dimensions capable of explaining 72.66% of the variance. The criteria for domain identification and item retention were eigenvalue>1.0 and items with factor loadings >0.4. The internal consistency by alpha Cronbach estimated the reliability of the instrument in .89; the dimensions remained between .84 and .90. Temporal stability corresponded .89 for the instrument and the dimensions remained between .83 and.90. As it was expected this result, for the instruments not evaluating the function as specifically, on the other hand, they evaluate behaviors contributing to it, as an example of the maintenance of sexual activity and its satisfaction. The solution and the data presented were consistent with the proposal of creation of the instrument and met theoretical expectations for the evaluation of PE. For this set of analysis, the results were provided to the Brazilian adaptation of the IPE evidence of validity based on the internal structure.
