Validity and Reliability Study of the Prolonged Grief Disorder- Caregiver Turkish Form

The aim of this study was to adapt the Prolonged Grief Disorder - Caregiver Form (PG-12), which is used to measure grief symptoms of caregivers providing care to their relatives with a chronic diseases that cause functional disability to Turkish and to investigate its psychometric properties. We also aimed to investigate the prevalence of prolonged grief disorder in the caregiver sample.

The sample consisted of 120 adult participants (70.8% female) who acted as caregivers. The participants were administered Prolonged Grief Disorder-Caregiver Form, Zarit Caregiver Burden Scale, Beck Depression Inventory and Life Satisfaction Scale.

The results of confirmatory factor analysis showed that the single-factor structure of PG-12, consistent with the original form, was supported. PG-12 scores showed a positive correlation with depression and caregiver burden scores and a negative correlation with life satisfaction scores. The internal consistency coefficient of the scale was 0.85. The prevalence of prolonged grief disorder calculated using PG-12 was found to be 31.66%.

The results showed that PG-12 is a valid and reliable tool for assessing the grief symptoms of people who provides care for a relative. In addition, the prevalence of prolonged grief disorder in our study population was high. Additional studies are needed in Turkey to confirm this rate and develop new strategies for caregivers.
