The Patient Roles and Responsibilities Scale (PRRS) was developed to enable a broader evaluation of the impact cancer treatment, measuring 'real world' roles responsibilities such as caring for others financial employment responsibilities. Here, we report development initial validation.The 29-item PRRS from thematic analysis two interview studies with patients caregivers. In study, participants completed alongside Social Difficulties Inventory (SDI), main criterion measure concurrent validity, Functional Assessment Cancer Therapy - General WHO Quality Life-BREF (WHOQOL-BREF) additional convergent validity data. Questionnaires were at baseline, 7-days (PRRS only) 2 months. Demographic data patient characteristics collected baseline.One hundred thirty-five stage III/IV breast, lung or gynaecological melanoma least once. Five items performed poorly removed scale. final 16 core selected comprised 3 dimensions: family well-being, social life, identified in principal component analysis, accounting 61.5% total variance.
