چکیده
Background: Needs based biopsychosocial distress instrument for cancer patients (CANDI) is a scale based on needs arising due tothe effects of cancer.Objectives: The aim of this research was to determine the reliability and validity of the CANDI scale in the Turkish language.Patients and Methods: The study was performed with the participation of 172 cancer patients aged 18 and over. Factor analysis(principal components analysis) was used to assess construct validity. Criterion validities were tested by computing Spearman correlationbetween CANDI and hospital anxiety depression scale (HADS), and brief symptom inventory (BSI) (convergent validity) andquality of life scales (FACT-G) (divergent validity). Test-retest reliabilities and internal consistencies were measured with intraclasscorrelation (ICC) and Cronbach- .Results: A three-factor solution (emotional, physical and social) was found with factor analysis. Internal reliability ( = 0.94) andtest-retest reliability (ICC = 0.87) were significantly high. Correlations between CANDI and HADS (rs = 0.67), and BSI (rs = 0.69) andFACT-G (rs = -0.76) were moderate and significant in the expected direction.Conclusions: CANDI is a valid and reliable scale in cancer patients with a three-factor structure (emotional, physical and social) inthe Turkish language.
