Development and validation of oral chemotherapy self-management scale

With the increase of oral chemotherapy drugs, patients receiving cancer treatment prefer oral chemotherapy versus intravenous, given equal efficacy and toxicity. However, they need to take an active part in their care, which is vital with home-based oral therapy, therefore the self-management is important for patients with oral chemotherapy. Unfortunately, the development of self-management assessment tools for oral chemotherapy still lags behind.

The OCSMS item pool was formulated based on literature review and semi-structured interviews, An initial scale containing 5 dimensions and 38 items was constructed through research seminar, Delphi survey and pilot testing. To assess the validity and reliability, We recruited 261 patients from cancer hospital in China.

A 36-item scale was developed with five dimensions identified through factor analysis: daily life management, symptom management, medication management, emotional cognitive management and social support. Cronbach's coefficient Alpha, split-half coefficient, test-retest reliability and S-CVI/UA scores were 0.929, 0.773, 0.966 and 0.833, respectively, indicating that OCSMS has good reliability and validity.

The OCSMS is a valid, reliable measurement method of the self-management ability of patients with oral chemotherapy. The OCSMS shows potential as a tool to ensure the safety of patients with cancer. The OCSMS may help evaluate the effectiveness of interventions to improve the self-management ability of patients.
