Duchenne/Becker muscular dystrophy (DBMD) is a disorder of progressive muscle weakness that causes an increasing need for assistance with activities of daily living. Our objective was to assess the psychosocial health and contributing factors among female caregivers in families with DBMD. We conducted a survey of adult women among families with DBMD in the United States (US) from June 2006 through January 2007, collecting data related to the care recipient, perception of caregiving demands, personal factors, and socio-ecologic factors.
