Measurement Properties of the Anticipatory Grief Scale in a Sample of Family Caregivers in the Context of Palliative Care

• Background: The Anticipatory Grief Scale (AGS) consists of 27 items and was developed to measure grief before the death of a loved one. Although it was originally developed to be used in the context of demen- tia, the instrument is relevant in palliative care where family caregivers often face a complex and difficult situation before the patient’s death. Because family caregivers with high levels of anticipatory grief might have need for more support both during ongoing palliative care and in bereavement, it is important to use valid instruments to measure grief reactions in anticipation of the patient’s death. Aim: The aim was to evaluate the measurement properties of the AGS in a sample of family caregivers in palliative care. Methods: In this psychometric study, data were collected in the context of ongoing palliative care and 270 family caregivers were included in the study. The family caregivers completed a questionnaire, including the AGS and demographic questions. The factor structure (construct validity) of the scale was evaluated using exploratory factor analysis for ordinal responses. Ordinal alpha (α) was used to estimate internal consistency. Results: The results of the exploratory factor analysis suggested that there were measurement problems and inconsistencies concerning the original AGS. Further analysis supported that the number of items should be reduced from 27 to 13 items. Analysis of the remaining items sug- gested a two-factor solution. The two dimensions captured the Behavioral reactions and Emotional reactions of grief in family caregivers in pallia- tive care. Internal consistency was satisfactory for both scales, α=0.83 and α=0.84 respectively. Conclusions: This study resulted in a revised 13 item version of the AGS, including two dimensions. The instrument appears to be promising for use in palliative care and in research but the measurement properties of the revised AGS needs to be confirmed in further studies. Funding This study was supported by the Swedish Cancer Society.
