The Brief Perceived Cognitive Impairment Scale–Korean: A Validation Study

This study evaluated the reliability (ie, internal consistency reliability) and validity (ie, construct, convergent, concurrent, and known-group validity) of the Brief Perceived Cognitive Impairment Scale–Korean (BPCIS-K). Methods From a university hospital, 249 cancer patients participated. The BPCIS-K was constructed with 6 items evaluating key aspects of cognitive impairment in cancer patients. For internal consistency reliability, Cronbach's α and item-total correlations were evaluated. For construct validity, confirmatory factor analysis was performed. For convergent validity, Pearson correlations were tested with the Functional Assessment of Cancer Therapy–Cognitive Function. For concurrent validity, Pearson correlations were tested with the Functional Assessment of Chronic Illness Therapy–Fatigue. For known-group validity, t tests were performed. Results The BPCIS-K showed high internal consistency reliability (Cronbach's α = .92; item-total correlations ranged from 0.76 to 0.81). Factor analysis confirmed the scale is unidimensional. It is highly associated with another validated cognitive impairment measure (r = -0.91, P
