In a frequentist framework, the exact fit of structural equation model (SEM) is typically evaluated with chi-square test and at least one index approximate fit.Current Bayesian SEM (BSEM) software provides measure overall fit: posterior predictive p value (PPP 2).Because noted limitations PPP 2, common practice for evaluating instead focuses on comparison, using information criteria or Bayes factors.Fit indices developed under maximumlikelihood estimation have not been incorporated into...
The current study explored parental processes associated with children's global self-esteem development. Eighty 5- to 13-year-olds and one of their parents provided qualitative quantitative data through questionnaires, open-ended questions, a laboratory-based reminiscing task. Parents who included more explanations emotions when writing about the lowest points in lives were likely discuss experienced negative past events child, which was child attachment security. Attachment concurrent...
Latent class analysis (LCA) refers to techniques for identifying groups in data based on a parametric model. Examples include mixture models, LCA with ordinal indicators, and latent growth analysis. Despite its popularity, there is limited guidance respect decisions that must be made when conducting reporting LCA. Moreover, lack of user-friendly open-source implementations. Based contemporary academic discourse, this paper introduces recommendations which are summarized the SMART-LCA...
Acknowledging that the parent-child attachment is a dyadic relationship, we investigated differences between pairs of parents and preschool children based on gender configurations in association problem behavior. We looked at mother-daughter, mother-son, father-daughter, father-son dyads, but also compared mothers fathers, daughters sons, same versus different pairs. employed multigroup structural equation modeling to explore moderation effects sample 446 independent (2-5 years old) from...
Abstract This study explores retirement processes. State pension age is gradually increasing in many countries, including the Netherlands. The traditional pathway where individuals have a cliff-edge transition from full-time job with permanent contract to full appears be applicable an ever-smaller group of employees. Hence, more recently, ‘retirement’ viewed not as single out labour force but rather process determined by several intertwined contractual and financial aspects market. Research...
Background: Prebiotic fiber has been examined as a way to foster gut bacteria less associated with obesity. Tests of prebiotic in reducing obesity have occurred mainly animals, adults, and Caucasians when the highest rates are African American Latinx youth. Response is determined by pre-existing intestinal microbiota. The type microbiota varies based on diet physical activity (PA), so it important examine acceptability response those most at risk for Methods: This cluster randomized...
Factorial invariance is critical for ensuring consistent relationships between measured variables and latent constructs across groups or time, enabling valid comparisons in social science research. Detecting factorial becomes challenging when varying degrees of heterogeneity are present the distribution factors. This simulation study examined how changes means variances influence detection noninvariance, comparing Bayesian maximum likelihood fit measures. The design factors included sample...
Suicide has been the second leading cause of death for 18- to 24-year-olds in United States since 2011. The stress experienced by undergraduate college students potential increase one’s risk suicide. Resilience theory was used as a theoretical framework examine interplay between and protective factors. A cross-sectional correlational design assess mediating effects positive thinking and/or social support on suicide resilience 131 18 24 years old who completed an online survey. study found...
Ordinal missing data are common in measurement equivalence/invariance (ME/I) testing studies. However, there is a lack of guidance on the appropriate method to deal with ordinal ME/I testing. Five methods may be used testing, including continuous full information maximum likelihood estimation (FIML), robust FIML (rFIML), probit links (pFIML), logit (lFIML), and mean variance adjusted weight least squared combined pairwise deletion (WLSMV_PD). The current study evaluates relative performance...
This study explored the impact of race/ethnicity on three four essential characteristics self-determination—autonomy, self-realization, and psychological empowerment—directly assessed in National Longitudinal Transition Study-2. Specifically, was examined with six disability groups established previous research: high incidence disabilities (learning disabilities, emotional disturbances, speech language impairments, other health impairments), sensory (visual hearing cognitive (autism,...
Most dementia care is provided at home by family members. This caregiving places an additional burden on the members, which can negatively impact their physical and psychological well-being. The caregivers’ also contribute to behavioral problems in care-recipients. purpose of this study was examine mediating/moderating effects positive thinking (PT) relationship between (embarrassment/anger, patient’s dependency, self-criticism) care-recipients’ (memory, depression, disruption) a sample 100...
We examine longitudinal extensions of the two-method measurement design, which uses planned missingness to optimize cost-efficiency and validity hard-to-measure constructs. These designs use a combination two measures: “gold standard” that is highly valid but expensive administer, an inexpensive (e.g., survey-based) measure contains systematic bias response bias). Using simulated data on four occasions, we compared where gold standard measured at one or more occasions. manipulated nature...

Thirty-nine participants progressed PDD 25 remained normal.Bayesian-estimated disease-state models described an individual's across 12 subtests with a change point.Subtests measuring working memory, visuospatial processing ability, crystalized memory changed significantly 3 5 years before their nonzero...
Using register data from Statistics Netherlands (2009–2019), this paper examines whether the first employment contract is related to early career outcomes for a cohort of young workers who entered Dutch labour market in period late 2009–2013. Instead looking at timing isolated transitions between states, 6-year-long trajectories are considered identify differences paths. Applying Mixture Hidden Markov Model, eight distinct states quality characterized by different types and incomes...
Secondary data analysis using the National Longitudinal Transition Study-2 set was conducted to examine degree which autonomy, psychological empowerment, and self-realization (3 of 4 essential characteristics self-determination) play a mediating role in relationship between school-based factors postschool outcomes. The results suggest that large significant With over 50% indirect effects (i.e., aggregated on outcome constructs through self-determination constructs) significant, this provides...
It is often unrealistic to assume normally distributed latent traits in the measurement of health outcomes. If normality violated, item response theory (IRT) models that are used calibrate questionnaires may yield parameter estimates biased. Recently, IRT were developed for dealing with specific deviations from normality, such as zero-inflation (“excess zeros”) and skewness. However, these have not yet been evaluated under conditions representative bank development outcomes, characterized by...
This study conducted secondary analysis of data from the National Longitudinal Transition Study-2 (NLTS2) to examine degree which student, family, and school constructs predicted self-determination outcomes. Multi-group structural equation modeling was used predictive relationships between 5 4 7 developed NLTS2 outcomes (autonomy, psychological empowerment, self-realization) across disability groups. The pattern relationship groups complex. Only one construct—self-concept—showed a positive...
