Test-retest reliability of the Kuopio instrument for fathers (KIF): a questionnaire to assess fathers' feelings, experiences and preparation for their wife/partner's delivery.
OBJECTIVE
to assess the test-retest reliability of the Greek version of the Kuopio Instrument for Fathers (KIF) questionnaire that explores fathers' feelings, experiences and preparation for their wife/partner's delivery.


METHODS
the KIF questionnaire was translated into Greek, back translated and adapted to the Greek population. After a pilot test, it was administered to a sample of fathers. Originally, 149 fathers completed the KIF questionnaire, and they were asked to complete it once again 1-2 weeks later.


RESULTS
out of a sample of 149 fathers, 72 (48.3%) returned the retest questionnaire. Sixty-five of these fathers had completed all the items, and thus only these cases were included in the data analysis. The mean age of the sample was 35.42+/-7.55 years. For 34 (52.3%) fathers, this was their first child. The mean total test score of fathers for the 35-item scale that assessed the feelings related to their wife/partner's delivery was 99.09+/-11.88 and the mean total retest score was 102.30+/-9.99. The correlation coefficient between the two scores was 0.975 (p<0.001). The mean total test and retest scores for the 19-item scale that evaluated the experiences related to their wife/partner's delivery were 50.78+/-17.57 and 49.59+/-18.21, respectively. The correlation coefficient was 0.947 (p<0.001). The intraclass correlation coefficients for the items of both scales ranged from 0.73 to 0.99, exceeding 0.85 in most cases.


CONCLUSIONS
the test-retest properties of the KIF questionnaire in the Greek population proved to be very satisfactory. Future validation and longitudinal studies are necessary to refine the instrument.
