“…Numerous factors have been shown to adversely influence adherence, including increased complexity of the medication regimen (McDonald, Garg, & Haynes, 2002), longer duration of therapy (Haynes, McDonald, & Garg, 2002), unpleasant medication side effects (Partridge, Avorn, Wang, & Winer, 2002), and impaired cognitive functioning (Logan, Zelikovsky, Labay, & Spergel, 2003). Additional factors that influence adherence include health beliefs (Elliott, Morgan, Day, Mollerup, & Wang, 2001), family structure and dynamics (Fiese & Everhart, 2006; Gayer & Ganong, 2006; Leonard, Garwick, & Adwan, 2005), socioeconomic status (Blais, Beauchesne, & Levesque, 2006), cultural beliefs and practices (Rose & Garwick, 2003; Sidelinger et al, 2005), and communication with and trust in health care providers (Dimatteo, 2004).…”
