Effects of "Three Good Things" Intervention on Dyadic Coping Among Young and Middle-Aged Stroke Survivors and Their Spousal Caregivers.

AIM: To evaluate the effectiveness of the "Three Good Things" (TGT) intervention in improving dyadic coping, mutuality, and well-being among young and middle-aged stroke survivors and their spousal caregivers. METHODS: A parallel-group quasiexperimental design was used. One hundred young and middle-aged stroke survivors and their spousal caregivers were recruited and assigned to either the intervention (n = 50) or control group (n = 50). The intervention group received eight sessions of the TGT intervention plus routine care. Outcomes were assessed at baseline, immediately postintervention, and at one- and three-month follow-up. Intervention effects over time and role differences were examined using multilevel modeling. RESULTS: The intervention group showed significantly higher overall levels of dyadic coping, mutuality, and subjective well-being than the control group (all p < 0.05). Role differences were observed in delegated dyadic coping (p < 0.001), with spouses reporting higher levels than patients. Changes over time in delegated dyadic coping differed between patients and spouses (p = 0.010), and the intervention effect on mutuality was stronger among patients than among spouses (p = 0.001). CONCLUSION: The TGT intervention was associated with improvements in psychological and relational outcomes in young and middle-aged stroke survivors and their spousal caregivers.
