“…Gattellari et al (2001) observed that patients who perceived that they had shared the treatment decision with their physician were significantly more satisfied with the consultation, the amount of information and the emotional support received from their physician, than patients who perceived the treatment decision as having been made exclusively by themselves or their physician. Benefits that have been observed in patients with diseases other than cancer include: less stress, decreased levels of symptom distress and concern about illness, increased functional status, coping, control over illness, self-efficacy, understanding of and commitment to the treatment plan and satisfaction with their physician (Davison et al, 1995). Krupat et al (2000) observed that, in the case of surgical patients, more perception of control was related to more satisfaction with the care that patients had received during their hospital stay.…”
