Social support and adjustment in patients with sarcoma: the moderator effect of the disease phase.

This study examined the association between different types of perceived social support and adjustment of patients with sarcoma, and if these relationships would differ depending on the outcome measure and phase of disease. Forty-nine patients in the diagnostic phase, 43 in the treatment phase, and 59 in the follow-up phase were recruited. Participants completed the Medical Outcomes Study Social Support Survey Questionnaire, the Hospital Anxiety and Depression Scale, and World Health Organization Quality of Life Assessment. Positive social interaction, emotional/informational, affectionate, and tangible supports were significantly associated with depression scores, but not with anxiety. Except for affectionate support, all the associations with overall quality of life were significant. A moderating effect of the phase of the disease was also found in the association between tangible support and anxiety, and between affectionate support, depression, and overall quality of life. In clinical practice it is important to implement phase-specific psychosocial interventions and to take into consideration other factors beyond perceived social support while handling patients with sarcoma.
