Individual variation is increasingly recognized as important to psychopathology research. Concurrently, new methods of analysis based on network models are bringing perspectives mental (dys)function. This current work analyzed idiographic multivariate time series data using a novel methodology that incorporates contemporaneous and lagged associations in mood anxiety symptomatology. Data were taken from 40 individuals with generalized disorder (GAD), major depressive (MDD), or comorbid GAD...
Abstract Physiologic investigations of generalized anxiety disorder (GAD) have skewed toward assessment the autonomic nervous system, largely neglecting hypothalamic‐pituitary‐adrenal (HPA) axis variables. Although these systems coordinate—suggesting a degree symmetry—to promote adaptive functioning, most studies opt to monitor either one system or other. Using ratio salivary alpha‐amylase (sAA) over cortisol, present study examined symmetry between sympathetic (SNS) and HPA in individuals...
Clinical psychological science has seen an exciting shift toward the use of person-specific (idiographic) approaches to studying psychopathology and change in treatment at level individual.One commonly used method idiographic research is ecological momentary assessment (EMA).EMA offers a way sample individuals intensivelyoften multiple times per dayas they go about their lives.While these methods offer benefits such as greater validity streamlined data collection, many share concerns...
Abstract Although the application of network theory to posttraumatic stress disorder (PTSD) has yielded promising insights, lack equivalence between inter‐ and intraindividual variation limits generalizability these findings any one individual with PTSD. Instead, a better understanding how PTSD symptoms occur vary over time within an requires exploring idiographic structure To do so, present study used intensive repeated‐measures design estimate networks on person‐by‐person basis....
Expanding on recently published methods, the current study presents an approach to estimating dynamic, regulatory effect of parasympathetic nervous system heart period a moment-to-moment basis. We estimated second-to-second variation in respiratory sinus arrhythmia (RSA) order estimate contemporaneous and time-lagged relationships among RSA, interbeat interval (IBI), respiration rate via vector autoregression. Moreover, we modeled these at lags 1 s 10 s, evaluate optimal latency for dynamic...
Most sexual assault survivors disclose to informal supporters and receive both negative positive social reactions. Converging evidence suggests that the first months after are a period of increased support-seeking may be uniquely important survivors’ recovery, especially among at risk chronic post-traumatic stress alcohol misuse. However, no research has examined when how often talk about their what reactions they during this time. As such, goal study was characterize day-to-day...
Research on the link between respiratory sinus arrhythmia (RSA) and posttraumatic stress disorder (PTSD) has largely focused average levels of RSA. However, given that rapid shifts in parasympathetic tone are necessary to maintain adaptive cardiac variability, exclusive focus these tonic estimates provides an incomplete quantification regulation. The present study is a secondary analysis previously published data. This aimed address this limitation by examining dynamic regulatory effect...
