Integrating Item Accuracy And Reaction Time To Improve The Measurement Of Inhibitory Control Abilities In Early Childhood, Brooke E. Magnus, Michael T. Willoughby, Clancy B. Blair, Laura J. Kuhn

Psychology Faculty Research and Publications

Efforts to improve children’s executive function are often hampered by the lack of measures that are optimized for use during the transition from preschool to elementary school. Whereas preschool-based measures often emphasize response accuracy, elementary school-based measures emphasize reaction time (RT)—especially for measures inhibitory control (IC) tasks that typically have a speeded component. The primary objective of this study was to test in a preschool-aged sample whether the joint use of item-level accuracy and RT data resulted in improved scoring for three IC tasks relative to scores derived from accuracy data alone. Generally, the joint use of item-level accuracy and …

Objective

To evaluate the psychometric properties of questions that assess patient perceptions of patient-provider communication and design measures of patient-centered communication (PCC).

Methods

Participants (adults with colon or rectal cancer living in North Carolina) completed a survey at 2 to 3 months post-diagnosis. The survey included 87 questions in six PCC Functions: Exchanging Information, Fostering Health Relationships, Making Decisions, Responding to Emotions, Enabling Patient Self-Management, and Managing Uncertainty. For each Function we conducted factor analyses, item response theory modeling, and tests for differential item functioning, and assessed reliability and construct validity.

Results

Participants included 501 respondents; 46% had a high …

Invariant Two-Component Structure Of The Repeatable Battery For The Assessment Of Neuropsychological Status (Rbans), Elisabeth M. Vogt, Gregory D. Prichett, James Hoelzle

Psychology Faculty Research and Publications

The Repeatable Battery for the Assessment of Neuropsychological Status is a brief neurocognitive instrument used to evaluate cognitive functioning in clinical settings. Prior investigations of the factor structure have revealed subtle differences across samples. It was hypothesized that these differences are primarily the result of methodological decisions made by researchers. The present study utilized empirically supported extraction criteria (parallel analysis; minimum average partial procedure) and uniformly investigated 5 samples. RBANS data from 4 previously published studies (Carlozzi, Horner, Yang, & Tilley, 2008; Duff, Hobson, Beglinger, & O'Bryant, 2010; Duff et al., 2006; Wilde, 2006) were reanalyzed, and a new clinical …
