Utrecht Gender Dysphoria Scale - Gender Spectrum (UGDS-GS): Construct validity among transgender,nonbinary, and LGBQ samples

Abstract

Background: Researchers combined both versions of the original Utrecht Gender Dysphoria Scale (UGDS) to create a single gender spectrum version (UGDS-GS) which measures dissatisfaction with gender identity and expression over time as well as comfort with affirmed gender identity.

Aim: This study examined the construct validity of the newly revised, UGDS-GS.

Method: Tests of measurement invariance were conducted in stages to assess measurement invariance of the UGDS-GS across three groups: cisgender, binary transgender, and nonbinary/genderqueer.

Results: Findings indicate that the UGDS-GS functions acceptably in all three gender groups (configural and metric invariance). Also, across binary transgender and nonbinary/genderqueer groups, the measure functions very similarly with all four types of invariance. Item level findings highlight the specificity of the measure to distinguish experiences of binary transgender and nonbinary/genderqueer persons differently from cisgender LGBQ individuals.

Conclusions: The UGDS-GS demonstrates a large degree of invariance across binary transgender, nonbinary/genderqueer, and cisgender LGBQ subgroups; and therefore, findings indicate this revision to be a substantial improvement. This 18-item self-report, Likert-type scale measure is a) inclusive of all gender identities and expressions (e.g., transfeminine spectrum, transmasculine spectrum, genderqueer, nonbinary, cisgender); b) appropriate for use longitudinally from adolescence to adulthood; and c) administered at any point in the social or medical transition process, if applicable, or in community-based research focused on gender dysphoria that examines cisgender and transgender persons.     

Enhancing mental health and well-being outcomes for psychotherapy and counselling through idiographic analysis: A four-quadrant approach

Mental health and well-being outcomes in psychotherapy and counselling have largely been studied through the use of standardised nomothetic measurement. A key limitation is that nomothetic measurement and current statistical analyses do not necessarily capture the outcomes of the complicated and individual psychotherapy processes. There is an increased interest in the use of idiographic patient-reported outcome measures (I-PROMs), which are uniquely useful because they may explore areas of importance that are unexplored by nomothetic outcome measures. We argue that to optimise the value of I-PROMs, it is necessary to consider their contribution alongside standardised nomothetic measures. However, there are important considerations with respect to whether or not I-PROMs from different clients, or indeed from the same client, can be meaningfully explored at a team/service level, and alongside standardised nomothetic outcomes. We provide worked examples on real client data to show that delineating four quadrants of analysis is important to explore the breadth of information: (a) individual progress on single items, (b) individual progress by aggregated scores, (c) team/service-level progress by goal item/theme and (d) team/service-level progress by aggregated scores.     

Testing Differential Item Functioning in Small Samples

Abstract

Differential item functioning (DIF) is a pernicious statistical issue that can mask true group differences on a target latent construct. A considerable amount of research has focused on evaluating methods for testing DIF, such as using likelihood ratio tests in item response theory (IRT). Most of this research has focused on the asymptotic properties of DIF testing, in part because many latent variable methods require large samples to obtain stable parameter estimates. Much less research has evaluated these methods in small sample sizes despite the fact that many social and behavioral scientists frequently encounter small samples in practice. In this article, we examine the extent to which model complexity—the number of model parameters estimated simultaneously—affects the recovery of DIF in small samples. We compare three models that vary in complexity: logistic regression with sum scores, the 1-parameter logistic IRT model, and the 2-parameter logistic IRT model. We expected that logistic regression with sum scores and the 1-parameter logistic IRT model would more accurately estimate DIF because these models yielded more stable estimates despite being misspecified. Indeed, a simulation study and empirical example of adolescent substance use show that, even when data are generated from / assumed to be a 2-parameter logistic IRT, using parsimonious models in small samples leads to more powerful tests of DIF while adequately controlling for Type I error. We also provide evidence for minimum sample sizes needed to detect DIF, and we evaluate whether applying corrections for multiple testing is advisable. Finally, we provide recommendations for applied researchers who conduct DIF analyses in small samples.     

Replies to comments on "Which method delivers greater signal-to-noise ratio: Structural equation modelling or regression analysis with weighted composites?" by Yuan and Fang (2023)

Observational data typically contain measurement errors. Covariance-based structural equation modelling (CB-SEM) is capable of modelling measurement errors and yields consistent parameter estimates. In contrast, methods of regression analysis using weighted composites as well as a partial least squares approach to SEM facilitate the prediction and diagnosis of individuals/participants. But regression analysis with weighted composites has been known to yield attenuated regression coefficients when predictors contain errors. Contrary to the common belief that CB-SEM is the preferred method for the analysis of observational data, this article shows that regression analysis via weighted composites yields parameter estimates with much smaller standard errors, and thus corresponds to greater values of the signal-to-noise ratio (SNR). In particular, the SNR for the regression coefficient via the least squares (LS) method with equally weighted composites is mathematically greater than that by CB-SEM if the items for each factor are parallel, even when the SEM model is correctly specified and estimated by an efficient method. Analytical, numerical and empirical results also show that LS regression using weighted composites performs as well as or better than the normal maximum likelihood method for CB-SEM under many conditions even when the population distribution is multivariate normal. Results also show that the LS regression coefficients become more efficient when considering the sampling errors in the weights of composites than those that are conditional on weights.     

Classifying the variability in impact and active peak vertical ground reaction forces during running using DFA and ARFIMA models

The vertical ground reaction force (VGRF) during rear-foot striking running typically exhibits peaks referred to as the impact peak and the active peak; their timings and magnitudes have been implicated in injury. Identifying the structure of time-series can provide insight into associated control processes. The purpose here was to detect long-range correlations associated with the time from first contact to impact peak (TIP) and active peak (TAP); and the magnitudes of impact (IPM) and active peaks (APM) using a Detrended Fluctuation Analysis, and Auto-Regressive Fractionally Integrated Moving Average models. Twelve subjects performed an 8 min trial at their preferred running speed on an instrumented treadmill. TIP, TAP; IPM, and APM were identified from the VGRF profile for each footfall. TIP and TAP time-series did not demonstrate long-range correlations, conversely IPM and APM time-series did. Short range correlations appeared as well as or instead of long range correlations for IPM. Conversely pure powerlaw behaviour was demonstrated in 11 of the 24 time series for APM, and long range dependencies along with short range correlations were present in a further 9 time series. It has been hypothesised that control mechanisms for IPM and APM are different, these results support this hypothesis.     

Development and validation of a measure for emotion regulation at work: Introducing the Workplace Emotion Regulation Preference Inventory (WERPI)

Emotion regulation preference varies from person to person. However, the emotion regulation literature has mostly dichotomized preference to cognitive change and response modulation. The current investigation focused on development and validation of a comprehensive measure of workplace emotion regulation and examined the relationship between all emotion regulation strategies using a well-known taxonomy (Gross, 1998) and customer service performance. Preliminary evidence supports the validity of the new measure. The four groups identified in this analysis showed significant differences on customer service performance, suggesting that individual differences in regulation preference may be important to consider. Theoretical and practical implications of findings are discussed.

Staying and Returning dynamics of young children's attention

In this paper, we decompose selective sustained attending behavior into components of continuous attention maintenance and attentional transitions and study how each of these components develops in young children. Our results in two experiments suggest that changes in children's ability to return attention to a target locus after distraction (“Returning”) play a crucial role in the development of selective sustained attention between the ages of 3.5–6 years, perhaps to a greater extent than changes in the ability to continuously maintain attention on the target (“Staying”). We further distinguish Returning from the behavior of transitioning attention away from task (i.e., becoming distracted) and investigate the relative contributions of bottom-up and top-down factors on these different types of attentional transitions. Overall, these results (a) suggest the importance of understanding the cognitive process of transitioning attention for understanding selective sustained attention and its development, (b) provide an empirical paradigm within which to study this process, and (c) begin to characterize basic features of this process, namely its development and its relative dependence on top-down and bottom-up influences on attention.

Research Highlights

• Young children exhibited an endogenously ability, Returning, to preferentially transition attention to task-relevant information over task-irrelevant information.
• Selective sustained attention and its development were decomposed into Returning and Staying, or task-selective attention maintenance, using novel eye-tracking-based measures.
• Returning improved between the ages of 3.5–6 years, to a greater extent than Staying.
• Improvements in Returning supported improvements in selective sustained attention between these ages.

     

“To work,or not to work,that is the question” – Recent trends and avenues for research on presenteeism

ABSTRACT

This position paper brings together recent and emerging developments in the field of presenteeism. A critical synthesis of the evidence is needed due to persisting conceptual and methodological challenges as well as the increased volume of research in the field. This paper integrates emerging evidence and critical thinking into three areas: (1) concept, (2) measurement and methodological issues, and (3) the context of presenteeism. First, due to the variety of existing definitions, competing understandings, as well as the notion of positive presenteeism, it is important to reconsider the notion of presenteeism. Second, it is important to reflect on the measurement of the act of presenteeism and the productivity loss associated with that. Third, following the call to investigate presenteeism in specific contexts, it is important to explain the social, occupational, cross-cultural aspects, as well as the contemporary workplace changes. Based on this critical synthesis, we conclude by identifying recommendations for future research on presenteeism.
