Using confirmatory factor analysis to identify symptom clusters in individuals with acquired disabilities
Acquired disabilities, such as spinal cord injury, traumatic brain injury, limb loss (or other major limb injury/illness), or stroke, are typically accompanied by an array of physical and emotional symptoms and social challenges that interfere with recovery and affect quality of life (QOL). Despite advances in personalized medicine, interrelationships between symptoms remain unclear, and clinicians often treat individual symptoms in isolation. Th…
Measurement invariance of physical, mental, and social health PROMIS measures across individuals with spinal cord injury and traumatic brain injury
The Psychometric Properties of the Prioritizing Positivity Scale
The tendency to use pleasant states as a key criterion for how to structure daily life is called prioritizing positivity and has been measured with a 6-item scale. The Prioritizing Positivity Scale (PPS) is increasingly being used by researchers, but a comprehensive examination of its psychometric quality remains absent from the literature. Using three independent samples of adults (study 1: n = 176, study 2: n = 226, study 3: n = 240), we tested…
Psycholinguistic features, design attributes, and respondent-reported cognition predict response time to patient-reported outcome measure items
Completing a PROM requires multiple cognitive skills (e.g., memory, executive functioning) and appraisal processes. Response time is a means of operationalizing the amount or difficulty of cognitive processing, and this report indicates several aspects of PROM design that relate to a measure's cognitive burden. However, future research with better experimental control is needed

Determining a transitional scoring link between PROMIS® pediatric and adult physical health measures
Analyzing Skewed Continuous Outcomes With Many Zeros
Prevention researchers often analyze nonnegative continuous outcomes that are skewed and contain many zero observations. Variables with these features can arise when investigators measure low-base-rate behaviors (e.g., bullying, substance use) or use measurement tools that cannot differentiate individuals with low standing on the target construct. Common analytic procedures such as linear regression are often inappropriate for such data and may r…
Determining Power and Sample Size for Simple and Complex Mediation Models
Mediation analyses abound in social and personality psychology. Current recommendations for assessing power and sample size in mediation models include using a Monte Carlo power analysis simulation and testing the indirect effect with a bootstrapped confidence interval. Unfortunately, these methods have rarely been adopted by researchers due to limited software options and the computational time needed. We propose a new method and convenient tool…
Transitions between subclasses of bullying and victimization when entering middle school
We examined the effects of depressive symptoms, antisocial attitudes, and perspective-taking empathy on patterns of bullying and victimization during the transition from late elementary (4th grade to 5th grade) to middle school (6th grade) among 1,077 students who participated in the Youth Matters (YM) bullying prevention trial. Latent transition analysis was used to establish classes of bullying, victimization, bully-victimization, and uninvolve…
Effects of the KiVa Antibullying Program on Cyberbullying and Cybervictimization Frequency Among Finnish Youth
Cyberbullying among school-aged children has received increased attention in recent literature. However, no empirical evidence currently exists on whether existing school-based antibullying programs are effective in targeting the unique aspects of cyberbullying. To address this important gap, the present study investigates the unique effects of the KiVa Antibullying Program on the frequency of cyberbullying and cybervictimization among elementary…
Individual and Contextual Predictors of Cyberbullying
Classification of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome by Types of Fatigue
Persons with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) often complain of fatigue states (eg, postexertional malaise, brain fog) that are qualitatively different than normal, daily fatigue. Given the heterogeneous nature of ME/CFS, it is likely that individuals with this illness experience these fatigue types differently in terms of severity and frequency. It is also possible that meaningful subgroups of patients exist that exhib…
