Assessing anger and irritability in children: psychometric evaluation and normative data for the German version of the PROMIS® Parent Proxy Anger Scale

Purpose Anger and irritability are common and impairing symptoms in children. The PROMIS Anger scales assess self- and parent-reported irritable and angry mood over the past 7 days. The aim of this study was to evaluate the psychometric properties of the German version of the PROMIS Parent Proxy Short Form v1.0—Anger and to provide normative data. Methods To evaluate the psychometric properties, data from the study ADOPT Epidemiology were used. In this study, the PROMIS Anger Scale was administered to a population-based sample of n = 8746 parents of children aged 8–12 years. Psychometric analyses were carried out including the investigation of distribution characteristics, factor structure, model fit, internal consistency, and congruent validity. Normative data were calculated as percentile ranks and T-scores. Results The PROMIS Anger Scale demonstrated good psychometric properties, including satisfactory distribution characteristics, unidimensionality, good internal consistency as well as congruent validity. German normative data for the PROMIS Anger Scale are presented. Conclusion Based on first psychometric analyses, the German version of the PROMIS Anger Scale can be recommended for use in research and practice; however, further investigations using clinical data are needed. The normative data will allow researchers and clinicians an interpretation of the test scores in future applications.

Development and psychometric exploration of a semi-structured clinical interview for Misophonia

Misophonia is a newly described disorder associated with significant emotional distress, functional impairment, and a wide range of mental health problems (e.g., mood, anxiety, and personality disorders). Although recent studies have begun to validate self-report measures of misophonia, no psychometrically validated interviews have been developed. To advance a scientific understanding of misophonia, rigorously developed structured interviews are needed as a complimentary measurement approach to self-report inventories. Accordingly, the aim of this study was to develop and begin preliminarily validating a semi-structured clinical interview for misophonia. We took an iterative, grassroots approach to item generation and interview development involving key stakeholders (i.e., misophonia sufferers, experts in the field). Initial psychometric analyses from the current sample (n = 30) evidenced excellent preliminary estimates for internal consistency, convergent, discriminant, and predictive validity. Results from this study provide preliminary support for the Duke Misophonia Interview, and we recommend that this interviewer-rated measure be iteratively developed and refined using larger and more diverse samples.

An Attention-Based Diffusion Model for Psychometric Analyses

The emergence of computer-based assessments has made response times, in addition to response accuracies, available as a source of information about test takers’ latent abilities. The development of substantively meaningful accounts of the cognitive process underlying item responses is critical to establishing the validity of psychometric tests. However, existing substantive theories such as the diffusion model have been slow to gain traction due to their unwieldy functional form and regular violations of model assumptions in psychometric contexts. In the present work, we develop an attention-based diffusion model based on process assumptions that are appropriate for psychometric applications. This model is straightforward to analyse using Gibbs sampling and can be readily extended. We demonstrate our model’s good computational and statistical properties in a comparison with two well-established psychometric models.

Comprehensive Evaluation of the Functional Activities Questionnaire (FAQ) and Its Reliability and Validity

The Functional Activities Questionnaire (FAQ) is a collateral-report measure of difficulties in activities of daily living. Despite its widespread use, psychometric analyses have been limited in scope, piecemeal across samples, and limited primarily to classical test theory. This article consolidated and expanded psychometric analyses using tools from generalizability and item response theories among 27,916 individuals from the National Alzheimer’s Coordinating Center database who completed the FAQ. Reliability was evaluated with internal consistency, test–retest, and generalizability analyses. Validity was assessed via convergence with neurocognitive measures, classification accuracy with impairment stage, and confirmatory factor and item response theory analyses. Demographics did not impact scores and there was strong evidence for reliability (0.52-0.95), though coefficients were attenuated when restricted in range to diagnostic groups (e.g., normal cognition). There were strong correlations with neurocognitive measures ( rs: −.30 to −.59), strong classification accuracy (areas under the curve: .81-.99), and a single-factor model had excellent fit. All items evidenced strong item response theory discrimination and provided significant information regarding functional disability, albeit within a relatively restricted range. The FAQ is a reliable and valid measure of activities of daily living concerns for use in clinical/research settings. It best assesses mild levels of functional difficulty, which is helpful in distinguishing normal cognition from mild cognitive impairment and dementia.

The Revised Mood Rhythm Instrument: A Large Multicultural Psychometric Study

Background: Recent studies with the mood rhythm instrument (MRhI) have shown that the presence of recurrent daily peaks in specific mood symptoms are significantly associated with increased risk of psychiatric disorders. Using a large sample collected in Brazil, Spain, and Canada, we aimed to analyze which MRhI items maintained good psychometric properties across cultures. As a secondary aim, we used network analysis to visualize the strength of the association between the MRhI items. Methods: Adults (n = 1275) between 18–60 years old from Spain (n = 458), Brazil (n = 415), and Canada (n = 401) completed the MRhI and the self-reporting questionnaire (SRQ-20). Psychometric analyses followed three steps: Factor analysis, item response theory, and network analysis. Results: The factor analysis indicated the retention of three factors that grouped the MRhI items into cognitive, somatic, and affective domains. The item response theory analysis suggested the exclusion of items that displayed a significant divergence in difficulty measures between countries. Finally, the network analysis revealed a structure where sleepiness plays a central role in connecting the three domains. These psychometric analyses enabled a psychometric-based refinement of the MRhI, where the 11 items with good properties across cultures were kept in a shorter, revised MRhI version (MRhI-r). Limitations: Participants were mainly university students and, as we did not conduct a formal clinical assessment, any potential correlations (beyond the validated SRQ) cannot be ascertained. Conclusions: The MRhI-r is a novel tool to investigate self-perceived rhythmicity of mood-related symptoms and behaviors, with good psychometric properties across multiple cultures.

Stress for Success: Potential Benefits of Perceived and Actual Stress While Cruising

Understanding the effects of travel on the health of travelers could have profound effects on the tourism industry and behaviors of tourists. While psychometric analyses have suggested travel has the ability to relieve stress and improve one’s overall well-being, scant research has utilized physiological data to examine the effects of travel on health. The current study, guided by the cognitive activation theory of stress (CATS), compared self-reported diaries and physiological data (using heart rate monitors) to examine the effects cruising has on both perceived and actual stress. Results empirically validate the use of CATS as a theoretical framework for understanding travelers’ perceived and actual stress. Findings also inform specific guidance to both cruise management, on how to engineer cruise experiences based on stress, and individuals, on how to experience positive stress while traveling.
