Eudaemonic positive psychological health (PPH), such as purpose in life (PIL), may be maintained more than hedonic PPH, such as quality of life (QOL), for patients with amyotrophic lateral sclerosis (ALS) and their caregivers across the disease course. Furthermore, patients' and caregivers' PPH may impact one another. The present study examined (a) PIL and QOL variance structures; (b) PIL and QOL trajectories from diagnosis, approaching death, with disease severity; and (c) between-dyad and within-dyad relationships for PIL and QOL in patients with ALS and their caregivers.
