Parental depressive symptoms and marital intimacy as predictors of parent-child interaction: a family systems perspective
… interaction concurrently (at 54 months) and longitudinally (at first grade). In addition, interactions among the above variables assessed: (1) the association between actor depression and parent-child interaction as a function of partner depression, (2) marital intimacy as a buffer against …

Modeling longitudinal data with interval censored anchoring events
In many longitudinal studies, the time scales upon which we assess the primary outcomes are anchored by pre-specified events. However, these anchoring events are often not observable and they are randomly distributed with unknown distribution. Without direct observations of the anchoring events, …

Examining The Longitudinal Impact Of Assets And Income On Immigrant Health Behaviors
… a steady numerical increase. This study uses longitudinal data to determine the effects of culture and acculturation on the health behaviors of the foreign born. Drawing from the behavioral model of health service utilization for vulnerable populations: Gelberg, Andersen, & Leake, 2000), the …

Cognitive diagnosis modeling and applications to assessing learning
Chapter 1: Cognitive diagnosis models (CDMs) are restricted latent class models designed to assess test takers' mastery on a set of skills or attributes. With a wide range of applications in education and in psychopathology, various CDMs have been proposed and fitted to response data from different …

The role of genetic and environmental variation in the respiratory phenotype of alpha 1 antitrypsin deficiency
… significantly to gas transfer in regression models, and anti elastin antibodies were higher in HLA-DRB1*04 and HLA-DQA1*0301 homozygotes. Ozone levels contributed to the burden of disease in cross sectional and longitudinal models of pollution exposure, whilst PM10, NO2 and SO2 were …

Emotion regulation transmission in the context of parenting behaviors as predictors of adolescent substance use
… In the present study, cross-sectional and longitudinal structural equation modeling analyses were utilized to determine the relationship among these variables. In the cross-sectional analyses (n = 219), the sample was 55% male and were between the ages of 12 to 18 years (M = 15.12). In the …

Development and Feasibility Trial of a Cognitive Behavioural Self-Management Program for Inflammatory Bowel Disease
… (HRQoL) were examined using cross-sectional and longitudinal mediation models to identify intervention targets. In a cross-sectional mediation model, pain catastrophizing and illness-focused coping mediated the relationship between pain and HRQoL. In longitudinal models with pain at time 1, pain …

Approaches for Handling Time-Varying Covariates in Survival Models
Survival models are used in analysing time-to-event data. This type of data is very common in medical research. The Cox proportional hazard model is commonly used in analysing time-to-event data. However, this model is based on the proportional hazard (PH) assumption. Violation of this assumption …
