This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement …

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 …

Photographic Assessment Of Change In Trichotillomania: Psychometric Properties And Variables Influencing Interpretation, David C. Houghton, Maddison R. Franklin, Michael P. Twohig, Martin E. Franklin, Scott N. Compton, Angela M. Neal-Barnett, Stephen M. Saunders, Douglas W. Woods

Although photographic assessment has been found to be reliable in assessing hair loss in Trichotillomania, the validity of this method is unclear, particularly for gauging progress in treatment. The current study evaluated the psychometric properties of photographic assessment of change in Trichotillomania. Photographs showing hair loss of adults with Trichotillomania were taken before and after participating in a clinical trial for the condition. Undergraduate college students (N = 211) rated treatment response according to the photos, and additional archival data on hair pulling severity and psychosocial health were retrieved from the clinical trial. Photographic assessment of change was found …
