Perceived social support moderates relationship between (folded) Functional Status Score (FSS) and Center for Epidemiologic Studies Depression Scale (CES-D).
The negative relationship between (folded) FSS and CES-D scores is attenuated by level of perceived social support: solid straight line with steepest downward slope represents relationship in caregivers with lower than average (mean = 1 SD) social support; fine broken line with moderate downward slope represents relationship in caregivers with average social support (mean); broad broken line with mildest downward slope represents relationship in caregivers with higher than average (mean + 1 SD) social support.
