Dyad interventions after stroke show mixed but potentially moderate to large benefits on health-related quality of life for both survivors and caregivers.
Purpose To characterize the effects of dyad interventions on stroke survivor and caregiver health-related quality of life (HRQOL), participation, and activity outcomes.Methods Five databases were searched using: stroke AND social support/dyad relationships AND intervention. No date or language restrictions were applied. Title/abstract/full-text review and data extraction were conducted by two independent raters. Studies that tested between-group or within-group effects of an intervention that engaged both dyad members together in at least one intervention session and measured at least one outcome of interest (HRQOL, participation, or activity) in both dyad members were included.Results Among 64,988 records, 401 full-text articles were reviewed, and 17 studies were included. Three dyad intervention types were identified: stroke education and caregiver training, joint psychosocial interventions, and caregiver-mediated exercise. Effects on HRQOL were mixed. Among five studies that favored the intervention group on HRQOL, effects ranged from moderate to large among stroke survivors (Cohen’s d = 0.51 to 7.03) and caregivers (Cohen’s d = 0.66 to 7.90). Measures of caregiver activity and participation were rarely included.Conclusions There is emerging evidence for certain types of dyad intervention after stroke. Future research should examine the effectiveness and mechanisms of these dyad interventions and include measures of caregiver activity and participation.

Kringle et al. (2024) conducted a systematic review in stroke (n=17). Dyad interventions was evaluated on health-related quality of life (HRQOL), participation, and activity (Cohen's d 0.51-7.03 (survivors), 0.66-7.90 (caregivers)). Dyad interventions after stroke had mixed effects on health-related quality of life, with 5 studies showing moderate to large positive effects for survivors (Cohen's d 0.51-7.03) and caregivers.
