RESUMEN
Psychological stress has a profound effect on infertility and its treatment. The aim of this study was to develop a specific scale to determine distress levels among Iranian infertile women. In this cross-sectional study the samples included 300 women [145 fertile and 155 infertile] who completed the Infertility Distress Scale [IDS] form. Data was analysed using correlation method and main component analysis. These results show that all 21 items had a high correlation with the overall scale. Cronbach's alpha value was 0.91 for the entire list. Factor analysis results with 5 element extraction could identify 88% of overall variance with a special value higher than 1. According to results, the IDS questionnaire has enough admissibility and validity in the measurement of the infertility distress scale in Iranian infertile women
