A Review of the Psychometrics of Perinatal Grief Instruments

The intense emotional and psychological consequences of pregnancy loss have been studied for decades. With the growing body of literature regarding women's experiences of pregnancy loss, there is an increased need for high quality evidence that underpins perinatal grief and bereavement support interventions. In this paper, we describe and analyze the psychometric properties of existing tools (the Perinatal Grief Scale, the Perinatal Bereavement Scale, the Perinatal Grief Intensity Scale) developed specifically to measure grief following perinatal loss. The psychometric properties of these instruments are presented along with an assessment of their trustworthiness. Of the three perinatal grief instruments, the PGS is the most well-established measure of perinatal grief. The PBS, although promising, has not been as extensively tested as the PGS. The PGIS has compared favorably with the PGS and is also a good choice for use in perinatal bereavement studies despite its shorter history of use and less extensive psychometric testing.
