Test-retest reliability of the Short Form Survivor Unmet Needs Survey.
Asia-Pacific Journal of Oncology Nursing, 5 (2), 165-171.
Objective: Reliable and valid needs assessment measures are important assessment tools in cancer survivorship care. A new 30‑item short‑form version of the Survivor Unmet Needs Survey (SF‑SUNS) was developed and validated with cancer survivors, including hematology cancer survivors; however, test–retest reliability has not been established. The objective of this study was to assess the test–retest reliability of the SF‑SUNS with a cohort of lymphoma survivors (n = 40).
Methods: Test–retest reliability of the SF‑SUNS was conducted at two time points: baseline (time 1) and 5 days later (time 2). Test–retest data were collected from lymphoma cancer survivors (n = 40) in a large tertiary cancer center in Western Australia. Intraclass correlation analyses compared data at time 1 (baseline) and time 2 (5 days later). Cronbach’s alpha analyses were performed to assess the internal consistency at both time points.
Results: The majority (23/30, 77%) of items achieved test–retest reliability scores 0.45–0.74 (fair to good). A high degree of overall internal consistency was demonstrated (time 1 = 0.92, time 2 = 0.95), with scores 0.65–0.94 across subscales for both time points. Conclusions: Mixed test–retest reliability of the SF‑SUNS was established. Our results indicate the SF‑SUNS is responsive to the changing needs of lymphoma cancer survivors. Routine use of cancer survivorship specific needs‑based assessments is required in oncology care today. Nurses are well placed to administer these assessments and provide tailored information and resources. Further assessment of test–retest reliability in hematology and other cancer cohorts is warranted.
