Two hearts, one fear? Dyadic fear-of-progression and quality of life among Thai gynecologic-cancer survivors and caregivers

Among Thai gynecologic-cancer dyads, fear-of-progression erodes the individual's own quality of life but does not appear to does not appear to exert a cross-partner influence. Psycho-oncology programs should therefore screen and treat FoP in both survivors and caregivers, yet expect QOL gains to arise chiefly from direct, rather than cross-partner, relief of fear. Because the design was cross-sectional, temporal ordering cannot be inferred; FoP-QOL associations may be bidirectional (e.g., poorer QOL amplifying FoP and vice versa). Longitudinal, multi-wave APIM is needed to establish directionality. Future work should test domain-level QOL outcomes and longitudinal APIM to determine whether subtle cross-partner effects emerge in specific life domains.
