Valued Outcomes in the Cancer Experience (VOICE)™: Development and validation of a multidimensional measure of perceived control.

ABSTRACT

OBJECTIVE: Enhancing cancer patients' sense of control can positively impact psychological well-being. We developed and assessed the psychometric properties of Valued Outcomes in the Cancer Experience (VOICE)TM, a measure of patients' perceived control over key personal priorities within their cancer experience. METHODS: VOICE construction and testing were completed in three phases with separate participant samples (1) item generation and initial item pool testing (N = 459), (2) scale refinement (N = 623), and (3) confirmatory validation (N = 515). RESULTS: A 21-item measure was developed that captures cancer patients' sense of control in seven key domains (1) Purpose and Meaning, (2) Functional Capacity, (3) Longevity, (4) Quality Care, (5) Illness Knowledge, (6) Social Support, and (7) Financial Capability. VOICE demonstrated adequate internal consistency (full-scale α = 0.93; factor α = 0.67-0.89) and adequate to strong convergent and discriminatory validity. SIGNIFICANCE OF RESULTS: VOICE measures cancer patients' perceived control across a diverse range of personal priorities, creating a platform for elevating patient perspectives and identifying pathways to enhance patient well-being. VOICE is positioned to guide understanding of the patient experience and aid the development and evaluation of supportive care interventions to enhance well-being.
