Characteristics and well-being of informal caregivers: Results from a nationally-representative US survey.

Objectives: Given ongoing concerns about high levels of burden reported among some informal caregivers, the goal of this study was to characterize their sociodemographics, health, and well-being.

Methods: Using cross-sectional data from a large nationally representative survey in the United States (N = 438,712) we identified adults who provided informal care to friends or family members with a health problem, long-term illness, or disability. Descriptive statistics and propensity matching were used to characterize caregivers and compare their health and social support to sociodemographically-similar adults who were not caregivers.

Recruitment and retention rates in behavioral trials involving patients and a support person: a systematic review.

Background: Recruitment and retention challenges impede the study of behavioral interventions among patient-support person dyads.

Purpose: The aim of the study was to characterize recruitment and retention rates of behavioral interventions involving dyads.

Methods: Using PRISMA guidelines and with the guidance of a medical librarian, we searched Medline, EMBASE, Cochrane Controlled Trials, PsycInfo, and CINAHL from inception until July 2011.
