Abstract
Abstract
Background
Infertility history may have important implications for clinical practice and scientific discovery. Previous research on the validity of self-reported infertility measurements has been limited in scope and duration (< 5 years). In this study, we validated self-reported infertility history measures 15–23 years after fertility treatment initiation among women who utilized assisted reproductive technology (ART).
Methods
Women who received ART treatments from three Boston infertility clinics and who enrolled in a prior study (1994–2003) were re-contacted in 2018 for the AfteR Treatment Follow-up Study (ART-FS). Infertility history was collected from clinical records and two self-report questionnaires (at ART initiation and at ART-FS enrollment). Treatment history included specific details (fresh or frozen embryo transfers, number of cycles) and treatment recall prior to ART initiation. Self-reported infertility diagnoses included polycystic ovary syndrome (PCOS), endometriosis, uterine factor infertility, tubal factor infertility, diminished ovarian reserve/advanced maternal age, male factor infertility, and other/unknown. We compared self-reported measures from 2018 to self-reported and clinical data from prior study initiation, using Cohen’s kappa, sensitivity, specificity, and 95% confidence intervals.
Results
Of 2644 women we attempted to recontact, 808 completed the ART-FS, with an average follow-up of 19.6 years (standard deviation: 2.7). Recall of fertility treatment usage had moderate sensitivity (IVF = 0.85, Clomiphene/Gonadotropin = 0.81) but low specificity across different infertility treatment modalities (IVF = 0.63, Clomiphene/Gonadotropin = 0.55). Specific IVF details had low to moderate validity and reliability with clinical records. Reliability of recalled infertility diagnosis was higher when compared to self-report at ART initiation (PCOS K = 0.66, Endometriosis K = 0.76, Tubal K = 0.73) than when compared to clinical records (PCOS K = 0.31, Endometriosis K = 0.48, Tubal K = 0.62) and varied by diagnosis.
Conclusions
The ability of women to recall specific IVF treatment details was moderately accurate and recall of self-reported infertility diagnosis varied by diagnosis and measurement method.
