Discriminant validity is a valuable property of psychological scales that is usually investigated in the framework of the multitrait-multimethod approach. The establishment of discriminant validity demands the demonstration that the scale of interest representing a specific construct is unrelated to scales representing other constructs. The original implementation of the multitrait-multimethod ...

In a previous analysis of ImPACT scores relative to traditional neuropsychological tests (NP) and experimental tasks (Maerlender et al., 2010) we demonstrated convergent construct validity for the primary ImPACT test-score composites. A complete analysis of discriminant validity was not undertaken at that time. Here, test scores from the 54 collegiate football and hockey players were re-analyze...

Internal and external validity are threatened when subjects fail to complete an intervention and when they are lost at follow-ups. Accordingly, researchers and intervention staff continually strive to identify predictors of attrition and non-compliance. The present study investigated the success of models that incorporate program, family, and individual characteristic variables in predicting tr...

Confirmatory factor analysis was used to model a multitrait (attention deficit hyperactivity disorder [ADHD]-inattention, ADHD-hyperactivity/impulsivity, oppositional defiant disorder [ODD]) by multisource (mothers, fathers, and teachers) matrix to determine the convergent and discriminant validity of ratings by mothers, fathers, and teachers. Participants were 1,749 elementary school children ...

This study examined the factor structure, internal consistency, concurrent validity, discriminant validity, and discriminative validity of the Posttraumatic Cognitions Inventory (PTCI; E. B. Foa, A. Ehlers, D. M. Clark, D. F. Tolin, and S. M. Orsillo, 1999) in a sample of 112 individuals who had experienced a serious motor vehicle accident. Results generally supported the 3-factor structure of ...

Background: Oral feeding disorder is considered the disorder that most preterm infants experience. Sucking is the most appropriate way for oral feeding that may be immature in preterm infants. Regarding the increased risk of feeding problems in preterm infants investigating and monitoring the sucking patterns of preterm infants to present appropriate and timely intervention is recommended for t...

The main aim of this study was to establish the convergent and discriminant validity of a single-item measure of daily fatigue ("How fatigued do you currently feel?") in a daily diary context. Convergent validity of our measure was examined by relating it to a validated multiple-item measure of fatigue (Profile of Mood States; McNair, Lorr, & Droppelman, 1971) and to other daily (work-home inte...

We introduce a computer-based measure of ‘‘identity fusion,’’ a form of group alignment characterized by a visceral feeling of oneness with a group. Past measures of identity fusion (a single pictorial item and a 7-item verbal scale) have demonstrated a unique capacity to predict willingness to engage in extreme pro-group behaviors (e.g., fighting and dying for one’s group). The Dynamic Identit...
