1. Background In the UK, the NIHR vision sees ‘more patients and health professionals participating in health research’ [1]. Fundamental to health research is the testing of interventions through RCTs. Achieving high participation in RCTs has traditionally been difficult. Published data show that a minority of RCTs recruit successfully [2,3]. Recruitment problems reduce the total recruited samp...

Introduction Randomised Controlled Trials (RCTs) produce relative treatment effects that have high internal validity. However they may suffer from lack of external validity when used as inputs to cost-effectiveness analyses (CEA). If differences in RCT and CEA populations can be described by a set of observed covariates, then it is possible to adjust for these differences. A common approach is ...

Parents and adolescents often provide discrepant reports of adolescent and family behavior. Recent work indicates that scores from indirect measures of discrepancies between parent and adolescent reports, namely, statistical interactions between reports, longitudinally predict adolescent psychopathology. However, no previous work supports the criterion validity of interpreting scores from these...

The goal of this review is to highlight key elements underpinning excellent high-stakes summative assessment. This guide is primarily aimed at faculty members with the responsibility of assigning student grades and is intended to be a practical tool to help throughout the process of planning, developing, and deploying tests as well as monitoring their effectiveness. After a brief overview of th...

Using data from 468 parents and taking into account internal consistency, breadth of item content, within-scale factor analysis, and patterns of missing data, we developed short (94 items, 15 scales) and very short (36 items, 3 broad scales) forms of the Children's Behavior Questionnaire (CBQ; Rothbart, Ahadi, & Hershey, 1994; Rothbart, Ahadi, Hershey, & Fisher, 2001), a well-established parent...

Study objective: To examine the completion rate, internal reliability, and external validity of a home affluence scale based on adolescents’ reports of material circumstances in the home as a measure of family socioeconomic status. Design: Cross sectional survey. Setting: Data were collected from a school based study in seven schools in the north of England Cheshire over a five month period fro...

Four studies investigated the reliability and validity of thin slices of nonverbal behavior from social interactions including (a) how well individual slices of a given behavior predict other slices in the same interaction; (b) how well a slice of a given behavior represents the entirety of that behavior within an interaction; (c) how long a slice is necessary to sufficiently represent the enti...

Wisdom is a field of growing interest both inside and outside academic psychology, and researchers are increasingly interested in using measures of wisdom in their work. However, wisdom is a highly complex construct, and its various operationalizations are based on quite different definitions. Which measure a researcher chooses for a particular research project may have a strong influence on th...

This study examined the factor structure, reliability, and validity of the Antisocial Process Screening Device-Self-Report (APSD-SR), the Youth Psychopathic Traits Inventory (YPI), and the YPI-Short Version (YPI-SV) in detained female adolescents aged 12 to 17 years. The proposed three-factor structure of the YPI and YPI-SV was replicated, whereas the proposed three-factor structure of the APSD...
