Using structural equation modeling to study traits and states in intensive longitudinal data
No full textTraditionally, researchers have used time series and multilevel models to analyze intensive longitudinal data. However, these models do not directly address traits and states which conceptualize the stability and variability implicit in longitudinal research, and they do not explicitly take into account measurement error. An alternative to overcome these drawbacks is to consider structural equation models (state-trait SEMs) for longitudinal data that represent traits and states as latent variables. Most of these models are encompassed in the latent state-trait (LST) theory. These state-trait SEMs can be problematic when the number of measurement occasions increases. As they require the data to be in wide format, these models quickly become overparameterized and lead to nonconvergence issues. For these reasons, multilevel versions of state-trait SEMs have been proposed, which require the data in long format. To study how suitable state-trait SEMs are for intensive longitudinal data, we carried out a simulation study. We compared the traditional single level to the multilevel version of three state-trait SEMs. The selected models were the multistate-singletrait (MSST) model, the common and unique trait-state (CUTS) model, and the trait-state-occasion (TSO) model. Furthermore, we also included an empirical application. Our results indicated that the TSO model performed best in both the simulated and the empirical data. To conclude, we highlight the usefulness of state-trait SEMs to study the psychometric properties of the questionnaires used in intensive longitudinal data. Yet, these models still have multiple limitations, some of which might be overcome by extending them to more general frameworks. (PsycInfo Database Record (c) 2021 APA, all rights reserved).</p
Mixed-Effects Trait-State-Occasion Model:Studying the Psychometric Properties and the Person–Situation Interactions of Psychological Dynamics
No full textThe trait-state-occasion model (TSO) is a popular model within the latent state-trait theory (LST). The TSO allows distinguishing the trait and the state components of the psychological constructs measured in longitudinal data, while also taking into account the carry-over effects between consecutive measurements. In the present study, we extend a multilevel version of the TSO model to allow for the combination of fixed and random situations, namely the mixed-effects TSO (ME-TSO). Hence, the ME-TSO model is a measurement model suitable to analyze intensive longitudinal data that allows studying the psychometric properties of the indicators per individual, the heterogeneity of psychological dynamics, and the person–situation interaction effects. We showcase how to use the model by analyzing the items of positive affect activation of the crowdsourcing study HowNutsAreTheDutch (HoeGekisNL).</p
Does Functional Somatic Symptoms Measurement Differ Across Sex and Age? Differential Item Functioning in Somatic Symptoms Measured With the CIDI:Differential Item Functioning in Somatic Symptoms Measured With the CIDI
No full textFunctional Somatic Symptoms (FSS) are physical symptoms that cannot be attributed to underlying pathology. Their severity is often measured with sum scores on questionnaires; however, this may not adequately reflect FSS severity in subgroups of patients. We aimed to identify the items of the somatization section of the Composite International Diagnostic Interview that best discriminate FSS severity levels, and to assess their functioning in sex and age subgroups. We applied the two-parameter logistic model to 19 items in a population-representative cohort of 962 participants. Subsequently, we examined differential item functioning (DIF). "Localized (muscle) weakness" was the most discriminative item of FSS severity. "Abdominal pain" consistently showed DIF by sex, with males reporting it at higher FSS severity. There was no consistent DIF by age, however, "Joint pain" showed poor discrimination of FSS severity in older adults. These findings could be helpful for the development of better assessment instruments for FSS, which can improve both future research and clinical care.</p
Psychomotor therapy for individuals with mild intellectual disabilities or borderline intellectual functioning presenting anger regulation problems and/or aggressive behaviour:A qualitative study on clients' experiences
No full textBackground Psychomotor therapy (PMT) is often applied in Dutch clinical practice to address aggressive behaviour in individuals with mild intellectual disabilities or borderline intellectual functioning. However, the literature on clients' experiences is lacking. Methods An interpretative phenomenological analysis was used to analyse the semi-structured interviews of seven participants (19-60 years; four male, three female) who completed PMT targeting anger regulation problems. Results According to the participants, becoming aware of increasing tension and/or learning to downregulate the tension were the main goals of PMT. They emphasised both the possibility to learn by doing and the therapeutic alliance as essential to create a safe context, where participants can experiment with alternative behaviour. After completing PMT, participants perceived fewer aggressive outbursts and an increased self-esteem. Conclusions Participants in our sample experienced PMT as being helpful in targeting anger regulation problems and aggressive behaviour. The experiential nature of the program was perceived as a valuable aspect of PMT.</p
Early-life seasonal, weather and social effects on telomere length in a wild mammal
No full textEarly-life environmental conditions can provide a source of individual variation in life-history strategies and senescence patterns. Conditions experienced in early life can be quantified by measuring telomere length, which can act as a biomarker of survival probability in some species. Here, we investigate whether seasonal changes, weather conditions and group size are associated with early-life and/or early-adulthood telomere length in a wild population of European badgers (Meles meles). We found substantial intra-annual changes in telomere length during the first 3 years of life, where within-individual effects showed shorter telomere lengths in the winter following the first spring and a trend for longer telomere lengths in the second spring compared to the first winter. In terms of weather conditions, cubs born in warmer, wetter springs with low rainfall variability had longer early-life (3–12 months old) telomeres. Additionally, cubs born in groups with more cubs had marginally longer early-life telomeres, providing no evidence of resource constraint from cub competition. We also found that the positive association between early-life telomere length and cub survival probability remained when social and weather variables were included. Finally, after sexual maturity, in early adulthood (i.e., 12–36 months) we found no significant association between same-sex adult group size and telomere length (i.e., no effect of intrasexual competition). Overall, we show that controlling for seasonal effects, which are linked to food availability, is important in telomere length analyses, and that variation in telomere length in badgers reflects early-life conditions and also predicts first year cub survival.</p
CHILDREN'S THEME IN THE PIANO WORKS OF CHINESE COMPOSERS
No full textThe author of the article focuses on the children's theme in the work of Chinese composers, which is gaining more and more popularity in piano performance, also due to the fact that music addressed to a children's audience is an integral part of Chinese animation, which is conquering the world space now. The author draws attention to the figurative spheres characteristic of children's music, including the natural world, the world of society, children's characters and moods, the world of philosophy and folklore, as well as the specifics of the compositional forms that prevail today, the laconicism of which is related to Chinese miniature directly. The latter one is the expression of consciousness through an art form, whether it be carving a fruit stone, painting on glass, or drawing on rice paper.http://mediamusic-journal.com/Issues/13_6.htm
The impact of second- and third-language learning on language aptitude and working memory
No full textAn increasing number of adults learn more than one foreign language simultaneously. While the cognitive benefits of using multiple languages from birth have been studied extensively, little is known about possible cognitive benefits of learning multiple languages simultaneously in adulthood. Among the cognitive abilities which play a role in language learning, language aptitude (LA) and working memory (WM) are argued to be crucial. Traditionally considered relatively stable, recently they are advocated to be changeable. For example, one could imagine that learning new sounds, words, and structures in a language might both enhance the ability to temporarily hold and manage information (WM) and improve the ease with which subsequent languages are learnt (LA). Therefore, this study investigates whether LA and WM change while learning languages, and whether language learning intensity, i.e. learning one versus two foreign languages simultaneously, modulates this effect. Participants consisted of first-year and second-year Chinese university students majoring in English or English & Japanese/Russian. Data were collected twice with an interval of one academic year. The results show that all learners improved in certain aspects of LA and WM, and that among the first-year students, the two-foreign-languages learners outperformed their counterparts in WM improvement. The implications are discussed.</p
