Sentences with phrase «latent factor»

However, most of this research has not included measures of disorders that appear in childhood [e.g., attention - deficit / hyperactivity disorder (ADHD) or oppositional defiant disorder (ODD)-RSB-, nor has it considered the full range of possibilities for the latent structure of externalizing behaviors, particularly factor mixture models, which allow for a latent factor to have both continuous and categorical dimensions.

To avoid over - or underestimating the importance of each biometric latent factor, we restricted latent genetic (A), shared (C) and nonshared (E) environmental factors to 0 only when their factor loadings were estimated to be close to zero and not based on likelihood ratio tests as is common practice in the behavior genetics literature.

The indirect effects are either through just the wave 6 reckless driving latent factor or through both wave 4 sensation seeking and then the wave 6 reckless driving factor (double indirect).

Even so, from a more rigorous point of view, whether there is a single latent factor, or even a small group of principal components seems unlikely (Hojka et al. 2016).

Second, we assumed that all wave 1 and wave 4 effects on the unsafe driving items were indirect through the two wave 6 latent factors.

Upon identifying the latent factors of RBC via exploratory factor analysis, confirmatory factor analysis was performed on another sample of three hundreds and twenty - five students in a psychology course in order to validate the factors found.

All latent factors were significantly correlated, and all parameters estimated in the three - dimensional model of RBC were significant at p <.01, with standardized coefficients ranging from.20 to.78.

The unsafe driving items were connected to the wave 6 latent factors via probit or logistic regressions.

Conventionally, latent factors are represented by circles, errors as small arrows pointing on rectangles that represent manifest variables.

Other criteria of Goodness of - fit index (GFI) was used which represented the latent factors.

A confirmatory factor analysis (CFA) with the three dimensions as latent factors and items as observed variables was conducted separately for the version referring to father and the one referring to mother.

Thus, we tested a CFA in which items referred to both father and mother loaded, for each dimension, on the same latent factors (χ 2 (22) = 184.36, p =.000; CFI =.96; RMSEA =.06 -LRB-.05 — .07)-RRB-.

If (a) a structural equation model indicates that the direct - estimation items and the traits load on separate latent factors, and (b) these two latent factors both predict romantic interest, we would be persuaded that the direct - estimation items are measuring (and predicting) something important.

We estimated three conditional growth models by sequentially adding behavior problem latent factors.

The behavior problem measurement model (externalizing & internalizing symptoms) was tested before adding these latent factors as predictors to our two - part growth models.

Using data from the NLSY and structural equation models, we have constructed five latent factors (cognitive stimulation, parenting style, physical environment, child's ill health at birth, and ill health in childhood) and have allowed these factors, along with child care, to mediate the effects of poverty and other exogenous variables.

There was significant variance in both latent factors (ps < 0.05), and R2 for the indicators ranged from 0.46 to 0.86.

A measurement model is a model that examines the relationship between the latent factors and items related to them.

We found support for a model positing two latent factors (internalizing and externalizing).

First we determined the appropriate latent factors for child abuse and poor mental health and IPV perpetration through fitting separate measurement models.

The study used a structural equation modeling (SEM) framework, enabling the constructions of the latent factors EF and ToM derived from multiple measures, and therefore controlling the specific influences of each task or cognitive subdomain.

All six latent factors were significantly correlated with each other, with the exception of lack of emotional awareness and difficulties engaging in goal - directed behavioral when distressed.

We as Appraisers had to factor in to our opinions, as much as possible, potential latent factors as well when rendering opinions of value.

Other psychosocial factors, including a nonsupportive school environment, marital crises or psychological problems arising between parents, and poor parent - child attachment can also transform a latent tendency into a full - blown disorder.

By developing blood biomarkers and «immunologic signatures» related to antigen - specific T - cell responses, the researchers hope to identify individuals with latent TB infection who are at greatest risk for progression to active disease, allowing development of prevention strategies to target those at highest risk in areas with high rates of infection (usually low - and middle - income countries), as well as high income countries such as the U.S., where factors such as recent infection and HIV co-infection are associated with an increased risk of progression to active TB.
