To determine the face, content and construct validity of the Persian version of SCREENIVF for the infertile Iranian population.
This was a methodological study of the psychometric properties of SCREENIVF. This report describes process and principles used in translation and cultural adaption of SCREENIVF on 20 infertile couples.
During the process, cultural differences were quantified and taken into account. Results from qualitative face validity indicated that all items have equal or higher effect scores than 1.5(1.5 score effect), which shows the importance of these cases in infertile couples. In measuring the content validity ratio, all cases' scores were higher than 51% in Lawsche table (51% for 14 experts). The content validity ratio scores for all cases were equal or greater than 0.57, so items were identified as "essential". The entire instrument's internal correlation was estimated by using alpha Cronbach 0.89, which shows significant reliability. Results from construct validity represents that five factor structure of SCREENIVF has a good fit to the observe data.
The researchers must be aware of the culture-based constraints for data collected through the questionnaire. Therefore, further studies are highly recommended with the larger sample size.
It seems that the Persian version of SCREENIVF is valid and reliable and can be used to screen for emotional risk factors in infertile couples under treatment in infertility clinics in Iran.
