Psychosocial distress in rural palliative care: Preliminary longitudinal findings using the DADDS.

Abstract

Objectives: Palliative care enhances life, but rural Australia faces significant inequities, and psychosocial distress, an important yet often overlooked aspect, is under-recognized in these settings. This study examines how psychosocial distress evolves in rural palliative patients using the Death and Dying Distress Scale (DADDS).

Methods: A longitudinal study was conducted with palliative care patients in rural hospitals on Australia's east coast. Distress levels were measured using DADDS at multiple timepoints. Mixed-effects models assessed distress trajectories, while survival analyses (Weibull model) examined whether average distress changes predicted survival duration. For comparability, DADDS scores in mixed-effects models were standardized (0-100%), whereas survival analyses used raw total score changes.

Results: Adjusted mean total DADDS was 37.14 ± 22.67, with highest distress in fear of suffering and pain (49.95 ± 26.56) and lowest in fear of sudden death (30.26 ± 30.24). Distress followed a U-shaped trajectory: peaking early (52.68), declining mid (29.85) and late stages (28.26), then rising near death (53.05) (EMMs). Statistically significant changes included declines from early to mid-stage (β = -22.84, p = 0.007) and increases from late to near-death (β = 24.79, p = 0.003). Distress increased most from late to near-death in fear of suffering and death (β = 27.38, p = 0.006) and declined most from early to mid-stage in fear of dying (β = 28.01, p = 0.007). Higher distress correlated with shorter survival; each one-point increase in distress linked to a 6.97% survival reduction (time ratio = 0.930, β = -0.070, p < 0.001).

Significance of results: Psychosocial distress peaks in early palliative care and near death and is associated with reduced survival. Support should prioritize fears of suffering and pain during these stages, address fear of the dying process earlier, and remain attentive to persistent concerns such as loss of time and opportunity.
