title: The korean version of the body image scale-reliability and validity in a sample of breast cancer patients.
abstract: OBJECTIVE
  The Body Image Scale (BIS) developed in collaboration with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Study Group is a brief questionnaire for measuring body image concerns in patients with cancer. This study sought to assess the reliability and validity of the Korean version of the Body Image Scale (K-BIS).
  
  
  METHODS
  The participants consisted of 155 postoperative breast cancer patients (56 breast conserving surgery, 56 mastectomy, and 43 oncoplastic surgery). Subjects were evaluated using the K-BIS, the Body-Esteem Scale for Adolescents and Adults (BESAA), the Rosenberg Self-Esteem Scale (RSES), the Hospital Anxiety and Depression Scale (HADS), and the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF). Test-retest reliability and internal consistency were examined as a measure of reliability and validity was evaluated by convergent validity, discriminant validity and factor analysis.
  
  
  RESULTS
  Cronbach's α value was 0.943. The total score of the K-BIS was negatively correlated with the BESAA (r=0.301, p<0.001) and the body image facet in the WHOQOL-BREF (r=0.315, p<0.001). The total score of K-BIS positively correlated with the HADS (HAD-A: r=0.501, p<0.001, HAD-D: r=0.466, p<0.001). As for determining discriminant validity, scores were compared between the BCS subgroup, mastectomy subgroup, and oncoplastic surgery subgroup. Difference between the mastectomy subgroup and oncoplastic surgery subgroup was statistically significant (p=0.017). Factor analysis resulted in a single factor solution in three out of four anlyses, accounting for >59% variance.
  
  
  CONCLUSIONS
  The K-BIS showed good reliability and validity for assessment of body image in Korean breast cancer patients.
