The dimensionality of depression and anxiety instruments have recently been a source controversy.In European-wide sample patients after Traumatic Brain Injury (TBI), we aim to examine the factorial structure, validity, association Patient Health Questionnaire for (PHQ-9) Generalized Anxiety Disorder (GAD-7) instruments. This study is based on longitudinal observational data. We conducted analyses structure discriminant validity outcomes six-months TBI. also examined prevalence,...
The objective of this study was to provide a comprehensive examination the relation complicated and uncomplicated mild traumatic brain injury (mTBI) with multidimensional outcomes at three- six-months after TBI. We analyzed data from Collaborative European NeuroTrauma Effectiveness Research (CENTER-TBI) research project. Patients mTBI (Glasgow Coma scale (GCS) score 13-15) enrolled in were differentiated into two groups based on computed tomography (CT) findings: (presence any intracranial...
Abstract The present study examined the globally relevant predictors of adolescents’ subjective well-being (SWB) using data from Programme for International Student Assessment (PISA) 2015 Questionnaire. Guided by social-cognitive-behavior model (Suldo et al., 2008) and self-determination theory (Ryan & Deci, 2000), nine variables were selected subjected to a statistical procedure decision tree modeling (DTM). Our results showed that parent peer support most salient SWB across all eight...
Assessing outcomes in multinational studies on traumatic brain injury (TBI) poses major challenges and requires relevant instruments languages other than English. Of the 19 outcome selected for use observational Collaborative European NeuroTrauma Effectiveness Research TBI (CENTER-TBI) study, 17 measures lacked translations at least one target language. To fill this gap, we aimed to develop well-translated linguistically psychometrically validated instruments. We performed linguistic...
Traumatic brain injury (TBI) may lead to impairments in various outcome domains. Since most instruments assessing these are only available a limited number of languages, psychometrically validated translations important for research and clinical practice. Thus, our aim was investigate the psychometric properties patient-reported measures (PROM) applied CENTER-TBI study. The study sample comprised individuals who filled six-months assessments (GAD-7, PHQ-9, PCL-5, RPQ, QOLIBRI/-OS,...
Depression and anxiety are common following traumatic brain injury (TBI). Understanding their prevalence interplay within the first year after TBI with differing severities may improve patients' outcomes TBI. Individuals a clinical diagnosis of recruited for large European collaborative longitudinal study CENTER-TBI were screened patient-reported major depression (MD) generalized disorder (GAD) at three, six, twelve months post-injury (N = 1683). Data analyzed using autoregressive...
Post-concussion symptoms (PCS) are often reported as consequences of mild and moderate traumatic brain injury (TBI), but these not well documented in severe TBI. There is a lack agreement to which factors covariates affect the occurrence, frequency, intensity PCS among TBI severity groups. The present study therefore aims examine association between sociodemographic, premorbid, injury-related PCS. A total 1391 individuals (65% male) from CENTER-TBI were included analyses. frequency (number...
Abstract The transition to secondary school may negatively impact adolescents’ psychosocial and subjective well-being development. However, how develops during contextual factors, including aspects of ability grouping achievement composition, are associated with the development still require clarification. This study examined two measures well-being, life satisfaction satisfaction, investigate school. Moreover, context variations in form tracks school-level were analyzed examine extent which...
What shapes (occupational) success in later life? This study examines the differential importance of intelligence late childhood, socioeconomic background, and education across occupations. The quantity quality educational are thought to mediate other dimensions. We analyzed data from N = 4387 participants a German longitudinal large-scale multiple regression mediation models examine how childhood background predict income occupational status at different career stages. Both adulthood, with...
This study examined learning strategy use in mathematics among East Asian students educational systems. By employing latent class analysis on the Programme for International Student Assessment (PISA) 2012 data, we found four classes of types, namely memorization with metacognitive strategies (17.49%), (50.70%), elaboration only (10.33%), and (16.47%). The results showed that majority all seven systems belonged to 'metacognitive memorization' class, most adopted more than one type when...
For surveys of complex issues that entail multiple steps, reference points, and nongradient attributes (e.g., social inequality), this study proposes a new multiprocess model integrates ideal-point dominance approaches into treelike structure (IDtree). In the IDtree, an approach describes individual’s attitude then their tendency for using extreme response categories. Evaluation IDtree performance via two empirical data sets showed fit these better than other models. Furthermore, simulation...
Many education tests and psychological surveys elicit respondent views of similar constructs across scenarios (e.g., story followed by multiple choice questions) repeating common statements scales (one-statement-multiple-scale, OSMS). However, a respondent's earlier responses to the statement can affect later it (recursive carry-over effect), which violates local item independence assumption most measurement models. Ignoring this effect bias both estimated parameters for relations among...
Abstract Learning strategies have been recognized as important predictors of mathematical achievement. In recent studies, it has found that Asian students use combined learning strategies, primarily including metacognitive rather than rote memorization. To the best authors’ knowledge, there is only one prior study South Korea in investigations relationship between and mathematics achievement PISA 2012. study, were classified into groups using specific their achievements compared. There are...
Forber-Pratt and colleagues' Disability Identity Development Scale (DIDS) is the only disability identity measure that meets all criteria for rigorous scale development. Little known however about item fit DIDS.
A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from were selected for short-form (COPA-SF) based on cognitive diagnostic modeling (CDM) analyses. Both parametric nonparametric CDM correlational analyses conducted with responses 74 U.S. second-grade students COPA-SF. Results supported skills...
Learning behavior of East Asian students has been debated due to their striking performance on international large-scale assessments. This study was a comparative using latent class analysis examine students' perceptions learning strategies, reported strategy use, and the relationships between strategies self-efficacy across Taiwanese American in Program for International Student Assessment (PISA) 2012. The results indicate that items were perceived equivalently. (5%) less memorization than...
This study applied a three-step latent class analysis (LCA) approach to explore classes of learning strategy use and their moderation effects on the relationships between motivation mathematics performance.
