Analyzing Latent State-Trait And Multiple-Indicator Latent Growth Curve Models As Multilevel Structural Equation Models, Christian Geiser, Jacob Bishop, Ginger Lockhart, Saul Shiffman, Jerry L. Grenard

Latent state-trait (LST) and latent growth curve (LGC) models are frequently used in the analysis of longitudinal data. Although it is well-known that standard single-indicator LGC models can be analyzed within either the structural equation modeling (SEM) or multilevel (ML; hierarchical linear modeling) frameworks, few researchers realize that LST and multivariate LGC models, which use multiple indicators at each time point, can also be specified as ML models. In the present paper, we demonstrate that using the ML-SEM rather than the SL-SEM framework to estimate the parameters of these models can be practical when the study involves (1) a large ...


Temporal Contingency, C. R. Gallistel, Andrew R. Craig, Timothy A. Shahan Aug 2013

Temporal Contingency, C. R. Gallistel, Andrew R. Craig, Timothy A. Shahan

Psychology Faculty Publications

Contingency, and more particularly temporal contingency, has often figured in thinking about the nature of learning. However, it has never been formally defined in such a way as to make it a measure that can be applied to most animal learning protocols. We use elementary information theory to define contingency in such a way as to make it a measurable property of almost any conditioning protocol. We discuss how making it a measurable construct enables the exploration of the role of different contingencies in the acquisition and performance of classically and operantly conditioned behavior.


Acceptance And Commitment Therapy For The Treatment Of Posttraumatic Stress Among Adolescents, Michelle R. Woidneck, Kate L. Morrison, Michael P. Twohig Aug 2013

Acceptance And Commitment Therapy For The Treatment Of Posttraumatic Stress Among Adolescents, Michelle R. Woidneck, Kate L. Morrison, Michael P. Twohig

The number of individuals who meet diagnostic criteria for posttraumatic stress disorder (PTSD) is a small percentage of those exposed to trauma; many youth who do not meet criteria for PTSD continue to experience problematic posttraumatic stress (PTS) symptomology. Acceptance and commitment therapy (ACT) has shown preliminary effectiveness in the treatment of adult PTSD, but its effectiveness in treating PTS in youth is unknown. Using a multiple-baseline design, this study investigated the effectiveness of 10-weeks of ACT to treat PTS in youth. Four adolescents from a community sample and three adolescents from a residential sample participated. The Clinician Administered PTSD ...
