Analyzing people’s opinions, attitudes, sentiments, and emotions based on user-generated content (UGC) is feasible for identifying the psychological characteristics of social network users. However, most studies focus on identifying the sentiments carried in the micro-blogging text and there is no ideal calculation method for users’ real emotional states. In this study, the Profile of Mood Stat...

Mosaic plots are state-of-the-art graphics for multivariate categor ical data in statistical visualization. Knowledge structures mathematical models that belong to the theory of knowledge spaces psychometrics. This paper presents an application mosaic psychometric arising from underlying structure models. In simulation trials and with empirical data, scope this graphing method space is investig...

Online media platforms are increasingly using algorithms to select and present relevant information their audiences. This highlights the importance of exploring whether people aware algorithmic content recommendations. Although some studies have already investigated awareness, no standardized instrument has been developed yet assess this construct. In study, we therefore validated Algorithmic M...

Because of increased stress conditions in college students, updated psychometrics of the Perceived Stress Scale, 10-item version (PSS-10; S. Cohen & G. Williamson, 1988) are necessary. Participants were 281 undergraduates at 3 public universities. An exploratory factor analysis revealed a 2-factor structure measuring Perceived Helplessness and Perceived Self-Efficacy. Normative results, interna...

The alignment of sound intensity is of great importance particularly in the field of psychometrics. When sounds have different spectral content, loudness alignment becomes a more suitable tool. However, traditional models assume the source either to reside in a free field at 0° azimuth or in a diffuse field. To assess or align sound source loudness at different locations or with different radia...

Access OJJDP publications online at www.ojp.usdoj.gov/ojjdp with inadequate psychometrics, the failure to consider comorbidity (i.e., co-occurring conditions), problems with identifying sample characteristics, and a lack of information regarding when the assessments were conducted. They note that previous studies often did not define the timeframe for symptoms. However, distinguishing between l...

Numerous studies have suggested that shyness and sociability may be orthogonal personality traits, each of which are associated with distinct behavioural and psychophysiological correlates. Shyness has been linked to a variety of adverse mental health outcomes, and individuals who are high on both shyness and sociability (conflicted subtype) may be particularly at risk. The current study first ...

Throughout the history of games, representing the abilities of the various agents acting on behalf of the players has been a central concern. With increasingly sophisticated games emerging, these simulations have become more realistic, but the underlying mechanisms are still, to a large extent, of an ad hoc nature. This paper proposes using a logistic model from psychometrics as a unified mecha...

Background Growing evidence indicates that if disruptive behavior is left unidentified and untreated, a significant proportion of these problems will persist and may develop into problems linked with delinquency, substance abuse, and violence. Research is needed to develop valid and reliable measures of disruptive behavior to assist recognition and impact of treatments on disruptive behavior. T...

BACKGROUND The Geriatric Anxiety Inventory is a 20-item geriatric-specific measure of anxiety severity. While studies suggest good internal consistency and convergent validity, divergent validity from measures of depression are weak. Clinical cutoffs have been developed that vary across studies due to the small clinical samples used. A six-item short form (GAI-SF) has been developed, and while ...
