The Diagnostic and Statistical Manual of Mental Disorders (5th edition) Alcohol Use Disorder (DSM-5 AUD) criteria have been modified to reflect a single, continuous disorder. It is critical that we develop brief assessment measures that can accurately assess for DSM-5 AUD criteria in college students to assist in screening, referral, and brief intervention services implemented on college campuses. The present study sought to develop and assess for the psychometric properties of a brief 13-item measure designed to capture the full spectrum of the DSM-5 AUD criteria in a sample of college students...

BACKGROUND: Huntington disease is a fatal inherited neurodegenerative disease. Because the end result of Huntington disease is death due to Huntington disease-related causes, there is a need for better understanding and caring for individuals at their end of life. AIM: The purpose of this study was to develop a new measure to evaluate end of life planning. DESIGN: We conducted qualitative focus groups, solicited expert input, and completed a literature review to develop a 16-item measure to evaluate important aspects of end of life planning for Huntington disease...

BACKGROUND: Measuring the extent a behavioral treatment is sustained in usual care practice settings after initial support for implementation ends is challenging. Oftentimes dichotomous self-report measures are used to measure health program sustainment, but these measures may not adequately capture the quality or extent of behavioral treatment delivery. Using data collected from community based organizations that received support to implement the Adolescent Community Reinforcement Approach (A-CRA), a measure of the extent of sustainment was derived...

BACKGROUND: Current quality of life assessment tools for thyroid cancer survivors are not clinically useful due to the length of available questionnaires. Computerized adaptive tests are easily administered electronically and can achieve highly accurate and efficient results in minimal time. We aimed to develop a quality of life computerized adaptive tests (ThyCAT) for thyroid cancer survivors. METHODS: A bifactor item response theory model was fit to questionnaire responses from 1,078 North American Thyroid Cancer Survivorship Study participants-a longitudinal cohort study of quality of life in thyroid cancer survivors...

The Fitness-to-Drive Screening Measure(©) (FTDS) enables proxies to identify at-risk older drivers via 54 driving-related items, but may be too lengthy for widespread uptake. We reduced the number of items in the FTDS and validated the shorter measure, using 200 caregiver responses. Exploratory factor analysis and classical test theory techniques were used to determine the most interpretable factor model and the minimum number of items to be used for predicting fitness to drive. The extent to which the shorter FTDS predicted the results of the 54-item FTDS was evaluated through correlational analysis...

Recognising the identity of conspecifics is an important yet highly variable skill. Approximately 2 % of the population suffers from a socially debilitating deficit in face recognition. More recently the existence of a similar deficit in voice perception has emerged (phonagnosia). Face perception tests have been readily available for years, advancing our understanding of underlying mechanisms in face perception. In contrast, voice perception has received less attention, and the construction of standardized voice perception tests has been neglected...

J Peter Leeds
The theory of cognitive acuity (TCA) treats the response options within items as signals to be detected and uses psychophysical methods to estimate the respondents' sensitivity to these signals. Such a framework offers new methods to construct and score situational judgment tests (SJT). Leeds (2012) defined cognitive acuity as the capacity to discern correctness and distinguish between correctness differences among simultaneously presented situation-specific response options. In this study, SJT response options were paired in order to offer the respondent a two-option choice...

BACKGROUND: Progress testing is an assessment tool used to periodically assess all students at the end-of-curriculum level. Because students cannot know everything, it is important that they recognize their lack of knowledge. For that reason, the formula-scoring method has usually been used. However, where partial knowledge needs to be taken into account, the number-right scoring method is used. Research comparing both methods has yielded conflicting results. As far as we know, in all these studies, Classical Test Theory or Generalizability Theory was used to analyze the data...

INTRODUCTION: This research aims to estimate the relative risks of responsibility for a fatal accident linked to driving under the influence of cannabis or alcohol, the prevalence of these influences among drivers and the corresponding attributable risk ratios. A secondary goal is to estimate the same items for three other groups of illicit drugs (amphetamines, cocaine and opiates), and to compare the results to a similar study carried out in France between 2001 and 2003. METHODOLOGY: Police procedures for fatal accidents in Metropolitan France during 2011 were analyzed and 300 characteristics encoded to provide a database of 4,059 drivers...

In recent years, network models have been proposed as an alternative representation of psychometric constructs such as depression. In such models, the covariance between observables (e.g., symptoms like depressed mood, feelings of worthlessness, and guilt) is explained in terms of a pattern of causal interactions between these observables, which contrasts with classical interpretations in which the observables are conceptualized as the effects of a reflective latent variable. However, few investigations have been directed at the question how these different models relate to each other...

Background: Study objectives were to evaluate the Multiple Sclerosis Impact Scale (MSIS-29) and explore an optimized scoring structure based on empirical post-hoc analyses of data from the Phase III ADVANCE clinical trial. Methods: ADVANCE MSIS-29 data from six time-points were analyzed in a sample of patients with relapsing-remitting multiple sclerosis (RRMS). Rasch Measurement Theory (RMT) analysis was undertaken to examine three broad areas: sample-to-scale targeting, measurement scale properties, and sample measurement validity...

Behavioral momentum theory posits a paradoxical implication for behavioral interventions in clinical situations using Differential Reinforcement of Alternative Behavior (DRA): When alternative reinforcers are presented within the same context as the problem behavior, the added reinforcers may decrease the frequency of the behavior but also increase its persistence when the intervention ends. Providing alternative reinforcers in a setting that is distinctively different from that in which the target behavior occurs may avoid or reduce this increase in persistence...

Genotype by environment interaction in behavioral traits may be assessed by estimating the proportion of variance that is explained by genetic and environmental influences conditional on a measured moderating variable, such as a known environmental exposure. Behavioral traits of interest are often measured by questionnaires and analyzed as sum scores on the items. However, statistical results on genotype by environment interaction based on sum scores can be biased due to the properties of a scale. This article presents a method that makes it possible to analyze the actually observed (phenotypic) item data rather than a sum score by simultaneously estimating the genetic model and an item response theory (IRT) model...

Emerging adulthood is characterized by not only opportunity and transition but also a substantial increase in risk behaviors (Fosco et al. Journal of Family Psychology, 26(4), 565-575, 2012; Johnston et al. 2016). Building on prior research, we tested a mediational model hypothesizing that Family Check-Up (FCU) intervention effects on young adult risk would be mediated by increases in self-regulation, and that these changes would continue to affect risk behavior as high school youths transitioned to young adulthood...

Although psychiatric comorbidity in Parkinson's Disease (PD) has often been studied, the individual psychiatric symptoms have rarely been evaluated from a clinimetric point of view in an attempt to measure how much the symptoms have been bothering or distressing the PD patients. The current study is therefore aimed at evaluating from a clinimetric viewpoint the severity of psychiatric symptoms affecting PD patients by using the Hopkins Symptom Checklist (SCL-90-R) to show its measurement-driven construct validity (scalability)...

Background: The Body Awareness Rating Questionnaire (BARQ) is a self-report questionnaire aimed at capturing how people with long-lasting musculoskeletal pain reflect on their own body awareness. Methods based on classical test theory were applied to the development of the instrument and resulted in 4 subscales. However, the scales were not correlated, and construct validity might be questioned. Objective: The primary purpose of this study was to explore the possibility of developing a unidimensional scale from items initially collected for the BARQ using Rasch analysis...

OBJECTIVE: To develop a scale for emotional regulation using item response theory. METHOD: Eighteen Swanson Nolan and Pelham (SNAP-IV) items that loaded on an emotional dysregulation factor were submitted to Rasch analysis. After eliminating the items that violated Rasch criteria, the remaining items were examined for reliability and validated against the Conners' emotional lability index. RESULTS: A nine-item scale for emotional regulation was developed that satisfies the Rasch model and reliably distinguishes emotionally dysregulated/irritable children and adolescents...

This cross-sectional study analyzed social vulnerability, individual, and programmatic factors associated with low knowledge on HIV/AIDS among men who have sex with men (MSM). Respondent Driven Sampling (RDS) was used in 10 Brazilian cities. Knowledge scores on HIV/AIDS were estimated by Item Response Theory and categorized in three levels: high, medium, and low knowledge. Ordinal logistic regression was used for the analysis. Of the 3,746 MSM, 36.6%, 37.4%, and 26% showed high, medium, and low knowledge, respectively...

BACKGROUND: Healthy functioning relies on a variety of perceptual, cognitive, emotional, and behavioral abilities that are distributed throughout the normal population. Variation in these traits define the wide range of neurodevelopmental (NDD) and neuropsychiatric (NPD) disorders. Here, we introduce a new measure for assessing these traits in typically developing children and children at risk for NDD and NPD from age 2 to 18 years. METHOD: The Childhood Oxford-Liverpool Inventory of Feelings and Experiences (CO-LIFE) was created as a dimensional, parent-report measure of schizotypal and psychotic traits in the general population...

OBJECTIVE: The World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS) is intended to measure population prevalence of ADHD. The short version ASRS-6 has yet not been validated in a population setting. Our aim was to examine the validity of the ASRS-6 in a general population. METHOD: We used the Stockholm Public Health Cohort 2014. The convergent validity was assessed using item response theory (IRT). The discriminant validity was assessed by examining the correlation between the ASRS and known correlates...
