Received and perceived support subscales of the Berlin Social Support Scales in women diagnosed with breast cancer attending the breast clinic at Tygerberg hospital: structure and correlates

Abstract

Research in the field of psycho-oncology in South Africa is increasing, and there is a need for validated measures that assess factors associated with cancer, such as social support. The Berlin Social Support Scales are a battery of instruments that measure various types and functions of social support. The measure was originally developed for use among adult cancer patients, and their partners but has also been used among other clinical populations and healthy adults. We investigated the psychometric properties of the English version of the perceived and received sub-scales, Berlin Social Support Scales. Our sample included South African women ( N = 201) who were diagnosed with breast cancer and receiving treatment at a public health care facility. We administered several measures, including a demographic questionnaire, the Berlin Social Support subscales, the Duke-UNC Functional Social Support Questionnaire, and The Functional Assessment of Cancer Therapy to participants. Validity and reliability analyses were conducted. Factor analysis resulted in the retention of 17 items that clustered on two factors, namely received support and perceived support. The 17-item version of the Berlin Social Support Scale demonstrated strong reliability and validity in the sample. The two subscales are quick to administer, easy to interpret, and are a reliable measure of social support among breast cancer patients in South Africa.
