“…The present review also considered 12 non-RCT level III and IV studies, which did report positive results, across a range of domains. Psycho-education was reported to result in increased knowledge (Ferrell, Grant, Chan, Ahn, & Ferrell, 1995;Gagnon et al, 2002;Heinrich & Schag, 1985), improved self-efficacy in relation to coping (Lewis et al, 2008) or decision making (Gagnon et al, 2002), improved psychological well-being (Ferrell et al, 1995;Lewis et al, 2008) and reduction in caregiver burden (Pasacreta, Barg, Nuamah, & McCorkle, 2000). Problem solving interventions were reported to increase knowledge and problem solving ability (Bucher et al, 2001), and to reduce emotional tension (Cameron, Shin, Williams, & Stewart, 2004).…”
