Abstract
Background:
Disparities in breast cancer care are a worsening problem, requiring effective interventions that seek to address the delivery of high quality cancer care. Evidence from interventions designed to improve timeliness of care routinely identify lack of social support as one of the biggest barriers to care. And, social support is associated with adherence to treatment and survival. This study explores predictors of social support in a diverse population of cancer patients.
Patients and Methods:
This is a secondary analysis of baseline preliminary data from participants enrolled in Project SUPPORT, a randomized controlled comparative effectiveness trial designed to evaluate the impact of patient navigation with or without legal support and services, among women diagnosed with Stages 0-4 breast cancer between 2014-2016. Upon enrollment (within one month of a cancer diagnosis) we administered the Medical Outcomes Survey (MOS) of social support to all participants. This validated survey tool addresses functional support, including an overall score (range 0-95) and 4 distinct domains: Emotional/Informational, Tangible, Affectionate and Positive Social Interaction. Using chi-squared and t-tests we compared MOS scores across socio-demographic variables: age, race, language, insurance, health literacy and marital status.
Results:
Of the 103 participants, mean age is 54.5 (SD = 10.6); 56% Hispanic, 19% Black, and 22% White and 2% identified as other; the majority had public insurance 76%; 66% speak English, 21% Spanish and 13% Haitian Creole. Only 36% have adequate health literacy as measured by the BRIEF. Only 32% are currently partnered. The overall mean total score for social support is 75.8 (+/- 23.6), median of 78.9 (range 60.5 – 98.7). Participants scored lowest in tangible support (mean score 67.7 +/- 33.1) and highest in affective support (83.5 +/- 25.8). Non-White participants scored significantly lower across all domains (mean overall MOS score 73.3 +/- 2.6) when compared with Whites (mean overall MOS score 84.5 +/- 4.8, p value = 0.04). There were no differences in MOS scores by language, insurance, literacy or marital status.
Conclusion:
This is the first study to describe social support scores (overall and specific domains) from the validated MOS survey tool among a racially diverse, urban cancer patient population. We found significant differences by race. Studies to identify risks for low social support can help inform future targeted interventions.
