Résumé
Practical brief measures are needed for clinicians and researchers to identify and effectively manage cognitive impairment in cancer patients. 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). 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. 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 < .001) and moderately correlated with a fatigue measure (r = -0.52, P < .001). In known-group validity, female and patients undergoing treatment experienced more severe impairment than did male patients and patient awaiting treatment (P = .05, P = .08, respectively). The BPCIS-K is valid and reliable for assessing cancer patients' perceived cognitive impairment, particularly in concentration, memory, and executive functions. This study introduces a practical brief measure to clinicians and researchers.

BACKGROUND
Practical brief measures are needed for clinicians and researchers to identify and effectively manage cognitive impairment in cancer patients.
OBJECTIVE
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 < .001) and moderately correlated with a fatigue measure (r = -0.52, P < .001). In known-group validity, female and patients undergoing treatment experienced more severe impairment than did male patients and patient awaiting treatment (P = .05, P = .08, respectively).
CONCLUSION
The BPCIS-K is valid and reliable for assessing cancer patients' perceived cognitive impairment, particularly in concentration, memory, and executive functions.
IMPLICATION FOR PRACTICE
This study introduces a practical brief measure to clinicians and researchers.
