Actor-partner interdependence model (APIM) of perceived distress-social support interaction (buffering effect) regressed on health-related quality of life.

<p>Actor-partner interdependence model (APIM) of perceived distress-social support interaction (buffering effect) regressed on health-related quality of life.</p

The stress-buffering effect of perceived social support on health-related quality of life separately for patients and their caregiving partners (Hypothesis 2).

<p>The solid line with diamond symbols represents predicted values from the adjusted mixed model of low perceived social support (one standard deviation below the mean); the dashed line with square symbols represents predicted values of high perceived social support (one standard deviation above the mean). Low perceived distress refers to values of one standard deviation below the mean; high perceived distress refers to values one standard deviation above the mean. All variables were centered with a mean value of zero (z-standardization).</p
