Cross-Cultural Adaptation and Psychometric Validation of the French Version of the FAMCARE-Patient (FFP-16) Questionnaire for Outpatients With Advanced-Stage Cancer.

Context: Satisfaction is known to be correlated with the quality of care; it indicates the adequacy of the caregivers' responses in meeting the needs and expectations of patients. The FAMCARE-Patient questionnaire has been used to quantify satisfaction level in outpatients with advanced-stage cancers.

Objectives: To translate and cross-culturally adapt the FAMCARE-Patient questionnaire for French patients and to evaluate the psychometric properties of this version.

Methods: The original questionnaire was translated into French and adapted to French cultural context by an expert committee. The French FAMCARE-Patient Version 16 (FFP-16) was then pilot tested among 51 patients. Subsequently, psychometric properties were evaluated in a cross-sectional study by administrating the new tool to 176 adult outpatients with advanced-stage cancer who underwent oncological care at our university hospital.

Results: We performed a confirmatory factor analysis and assessed the reliability and validity of the questionnaire. The one-factor structure was confirmed, and it had an acceptable fit with a comparative fit index and root mean square error of approximation of 0.93 and 0.07, respectively. Internal reliability was high as shown by Cronbach's alpha (α = 0.95). Reproducibility was very good (intraclass correlation coefficient 0.91). The FFP-16 score was independent of the Eastern Cooperative Oncology Group and the overall Edmonton Symptom Assessment Scale distress scores. It was significantly but weakly correlated with anxiety, well-being, and overall quality of life (Spearman's correlation coefficient = -0.18, -0.20, and 0.30, respectively; P < 0.05).

Conclusion: We found the FFP-16 questionnaire to be a reliable and valid instrument for the assessment of satisfaction in French outpatients with advanced-stage cancer.
