Error-processing is increasingly examined using the error-related negativity (ERN) and error positivity (Pe) - event-related potentials (ERPs) that demonstrate trait-like properties and excellent reliability. The current study focuses on construct validity by applying a multitrait-multimethod approach, treating error-related ERPs (i.e., ERN, Pe and the difference between error minus correct, re...

This study replicates and extends prior studies of the dimensionality, convergent, and external validity of African Self-Consciousness Scale scores with appropriate exploratory factor analysis methods and a large gender balanced sample (N = 348). Viable one- and two-factor solutions were cross-validated. Both first factors overlapped significantly and were labeled "Embracing African Heritage." ...

The aim of this study was to translate the Dula Dangerous Driving Index (DDDI) into Chinese and to verify its reliability and validity. A total of 246 drivers completed the Chinese version of the DDDI and the Driver Behavior Questionnaire (DBQ). Specific sociodemographic variables and traffic violations were also measured. A confirmatory factor analysis confirmed the internal structure of the D...

The Addiction Severity Index--Multimedia Version (ASI-MV) is a CD-ROM-based simulation of the interviewer-administered Addiction Severity Index (ASI). Clients in treatment (N = 202) self-administered the ASI-MV to examine the test-retest reliability, criterion validity, and convergent-discriminant validity of the ASI-MV. Excellent test-retest reliability was observed for composite scores and se...

OBJECTIVES To assess the reliability and validity of the Brazilian version of the Attentional Function Index. METHOD Methodological study. The sample was made up of 138 students from an undergraduate nursing course. The psychometric properties were assessed through the convergent construct validity, using the Brazilian version of the Attentional Function Index and the Portuguese-language vers...

This report examines the construct of information systems quality. It is measured with the use of four questionnaire items that elicit perceptions of quality from the end users of the information system. These items query the level of functionality, information sufficiency, response time, flexibility, ease of use and overall quality of the system. The representational assumptions of the instrum...

This article describes the development and validation of a brief self-report scale for diagnosing anorexia nervosa, bulimia nervosa, and binge-eating disorder. Study 1 used a panel of eating-disorder experts and provided evidence for the content validity of this scale. Study 2 used data from female participants with and without eating disorders (N = 367) and suggested that the diagnoses from th...

This study evaluated the Beliefs about Medicine Questionnaire to explore adherence to adjuvant endocrine therapy after treatment for breast cancer (BMQ-AET). Factor structure of the BMQ-AET was explored alongside internal consistency, convergent validity and acceptability. The BMQ-AET Specific Scale fitted the original 10 item model. Internal consistency of the BMQ-AET was much improved compare...
