Latent variable models of alcohol-related constructs.

چکیده
This study examines the improvement in validity coefficients and structural relationships derived from formally modeling latent variables of adverse alcohol-related constructs. Results of a confirmatory factor analysis of responses from 8,755 participants in the 1988 National Household Survey of Drug Abuse support a three-factor model of alcohol abuse, dependence, and adverse consequences. A comparison of construct intercorrelations shows latent variables to be superior to measurement approaches using unweighted sums, quantity x frequency calculation, and single-item measurement.

RUNNING HEAD: Multilevel Analysis of Climate Effects Doubly Latent Multilevel Analyses of Classroom Climate: An illustration
Many classroom climate studies suffer from two critical problems. They: (a) treat climate as a studentlevel (L1) variable in single-level analyses instead of a classroom-level (L2) construct in multilevel analyses; and (b) rely on manifest-variable models rather than latent-variable models that control measurement error at L1 and L2, and sampling error in the aggregation of L1 ratings to form L...
متن کاملUsing multivariate generalized linear latent variable models to measure the difference in event count for stranded marine animals
BACKGROUND AND OBJECTIVES: The classification of marine animals as protected species makes data and information on them to be very important. Therefore, this led to the need to retrieve and understand the data on the event counts for stranded marine animals based on location emergence, number of individuals, behavior, and threats to their presence. Whales are g...
متن کاملSensation seeking explains the relation between behavioral disinhibition and alcohol consumption.
Research using latent variable analysis revealed a strong relation between behavioral disinhibition, as measured by the MacAndrew and Socialization scales, and drinking habits (Earleywine, Finn, & Martin, 1990). Theoretical reasons for this link remain unclear. Each of these constructs could relate to a third variable that could account for the covariation between them. Sensation seeking seemed...
متن کاملGeneralized Linear Latent Variable Models for time dependent data
Latent variable models are a fundamental tool for the analysis of multivariate data. The importance of such models is due to the crucial role that latent variables play in many fields, e.g. psychological and educational, socioeconomic, biometric, where often constructs are not directly observable. In these contexts, the different nature of the observable variables often causes theoretical and p...
متن کاملIntegrating Person-Centered and Variable-Centered Analyses: Growth Mixture Modeling With Latent
Background: Many alcohol research questions require methods that take a person-centered approach because the interest is in finding heterogeneous groups of individuals, such as those who are susceptible to alcohol dependence and those who are not. A person-centered focus also is useful with longitudinal data to represent heterogeneity in developmental trajectories. In alcohol, drug, and mental ...
