Aims/background: Assessing the intensity of perinatal grief is very important for identifying the more complex cases in mothers and fathers. Despite this, there are few assessment tools available. The aim of this study was to analyse the psychometric properties (factorial structure, reliability, and validity) of the Spanish version of the Perinatal Grief Intensity Scale (PGIS).
Design/methods: An online survey was completed by 291 mothers and fathers who had suffered perinatal loss in the previous six years.
Results: The results showed adequate fit indexes for the three-factor model of the PGIS: reality, confront others, and congruence. Reliability values for the overall scale and subscales were adequate. Finally, with regard to validity, significant (p < .05) and positive relationships were found with levels of complicated grief, event centrality, guilt, anxiety, and depression. There were also differences depending on whether participants exhibited high or low levels of complicated grief, and on the number of weeks of pregnancy at the time of the loss.
Conclusion: In conclusion, the Spanish adaptation of the PGIS has adequate reliability and validity scores and a factorial structure consistent with the original version.
