AI Insight
This study validated the Perinatal Grief Scale (PGS) for use in fathers who experienced stillbirth or miscarriage, analyzing data from 276 Italian men. Researchers identified a score threshold of 92 or higher that effectively identifies fathers at high risk for trauma-related symptoms, with 81% sensitivity and specificity. The PGS showed strong validity when compared against three established trauma assessment instruments, with fathers scoring above the threshold having 19 times higher odds of experiencing significant trauma symptoms.
Why it matters
This is the first validation of a grief screening tool specifically for fathers after pregnancy loss, addressing a significant gap in perinatal mental health research. The identified threshold provides clinicians with an evidence-based screening cutoff to identify bereaved fathers who may need additional psychological support or intervention.

Background. The Perinatal Grief Scale (PGS) is a widely used instrument for assessing grief following pregnancy loss, yet no study has validated it specifically in men despite documented use in several studies. This gap is critical given fathers’ persistent underrepresentation in perinatal bereavement research and the absence of empirically supported screening thresholds for this population. Methods. This cross-sectional validation study used data from the OPALE project (Observatory on PerinatAL hEalth) conducted by the CiaoLapo Foundation in Italy. Among 276 fathers who experienced stillbirth or miscarriage, we examined criterion validity by testing the association between PGS scores and trauma-related symptomatology assessed via three validated instruments: the Revised Impact of Event Scale (RIES, n=103), National Stressful Events Survey Short Scale (NSESSS, n=95), and SCL-90 (n=173). We systematically tested multiple threshold combinations to identify optimal discriminative performance. Results. The PGS demonstrated excellent criterion validity. The optimal threshold (PGS >=92) showed sensitivity 81.0%, specificity 81.8%, and Youden’s J index 0.628. Fathers scoring >=92 had 19.12 times the odds of high trauma symptoms (95% CI: 9.35 to 39.14, p<0.001). ROC analysis yielded AUC=0.829 (95% CI: 0.778 to 0.880). Associations remained robust across all three trauma instruments in stratified analyses and after adjusting for time since loss, father’s age, living children, and loss type. Conclusion. This is the first men-specific validation of the PGS, demonstrating strong criterion validity and establishing a clinically meaningful screening threshold (>=92) for identifying fathers at elevated risk following perinatal loss.
