Learning Objective 1: The learner will be able to compare and contrast impact of cancer treatment on actual and desired functional status.

Learning Objective 2: The learner will be able to identify individual characteristics that impact functional status during cancer treatment.

A major focus of oncology nursing is maintaining quality of life including ability to perform daily activities (functional status) in individual’s undergoing cancer treatment.  Research has shown that functional status declines during both radiation therapy and chemotherapy. Treatment-related side effects, age, race/ethnicity, education, employment, and living situation are associated with functional status during cancer treatment. Vulnerable populations such as the elderly with multiple co-morbidities are especially susceptible to decline in functional status during cancer treatment.

Current focus on patient-centered care requires that patient preferences (desires), needs, and values guide clinical decisions. Many studies have examined actual functional status in individuals undergoing cancer treatment. Few studies have measured desired functional status or those activities that patients prefer to do during their treatment. The Comprehensive Inventory of Functioning-Cancer (CIF-CA), derived directly from the role function mode of the Roy Adaptation Model, is a novel instrument that measures both actual and desired functional status.

A study will be initiated to examine the relationship between individual characteristics and desired functional status in approximately 100 men and 100 women with stage I-III solid tumors currently receiving adjuvant chemotherapy or radiation therapy. Further development and testing of the CIF-CA will be undertaken.

Data will be obtained once during an individual’s chemotherapy or radiation therapy. Participants will be asked to complete a demographic data questionnaire and the CIF-CA.  Psychometric tests of validity and reliability will be conducted on the CIF-CA. Differences in functional status by individual characteristics will be explored using x2, t –test, or ANOVA. Multiple regression analysis will be used to model desired functional status as a function of individual characteristics.

Information gained from this study will provide nurses with information to identify patients who are particularly vulnerable to decline in functional status and intervene early on in treatment to support desired activities.
