Development of a Brief Self-Report Measure of Work-Related Cognitive Limitations in Breast Cancer Survivors

Abstract

Objective: To develop a brief, reliable self-report measure of work-related cognitive limitations using a cross-validation method and to assess the correlation of that measure with an established self-report measure of generic cognitive limitations in cancer survivors. Method: A pooled dataset of working (e.g., managerial, sales, services, professional/technical, clerical) breast cancer survivors (n = 228) completed a self-report measure of work-related cognitive limitations, the Cognitive Symptom Checklist-Work-59 (CSC-W59). A cross validation technique was employed such that the pooled participants were randomized into two separate groups in order to conduct exploratory factor analysis (EFA) of the CSC-W59 with one group and validate the results of the EFA with the other group. A subset of this pooled dataset (breast cancer survivors, n = 133) also completed a self-report measure of generic cognitive limitations, the Functional Assessment of Cancer Therapy-Cognition (FACT-Cog) which measures such dimensions as subjectively perceived cognitive impairment, others perception of cognitive impairment, and effects of cognitive impairment on quality of functioning. Results: The EFA of the 59 items in the CSC-W59 on randomized group 1 (n = 114) resulted in the identification of 21 items with a consistent factor loading of .4 or higher on three separate subscales (Memory, Executive Function, and Task Completion). The consistency of the factor structure on these 21 items was validated on randomized group 2 (n = 114) which demonstrated the same 21 items loading at .4 or higher on the same three subscales. These findings resulted in a brief 21-item, self-report measure referred to as the Cognitive Symptom Checklist-Work-21(CSC-W21). The CSC-W21 demonstrates good internal reliability ( = .88) and accounts for 68% of the variance in a measure of generic cognitive function ( < .001) suggesting the CSCW21captures some commonalities of limitations in global cognition.
