Many psychological concepts are unobserved and usually represented as latent factors apprehended through multiple observed indicators. When multiple-subject multivariate time series data are available, dynamic factor analysis models with random effects offer one way of modeling patterns of within- and between-person variations by combining factor analysis and time series analysis at the factor level. Using the Dirichlet process (DP) as a nonparametric prior for individual-specific time series parameters further allows the distributional forms of these parameters to deviate from commonly imposed (e...

INTRODUCTION: It has been argued that as smoking prevalence declines, the remaining smokers represent a "hard core" who are unwilling or unable to quit, a process known as hardening. However, as recently shown, the general smoking population is softening not hardening (i.e., as prevalence falls, more quit attempts and lower consumption among continuing smokers). People with psychological distress smoke more, so they may represent hard-core smokers. METHODS: Using cross-sectional time series analysis, in 2016-2017 changes in quit attempts and cigarette consumption were evaluated over 19 years among smokers with serious psychological distress (Kessler-6 score ≥13) based on the National Health Interview Survey (1997-2015), controlling for sociodemographic variables...

Student musicians are at risk for noise-induced hearing loss (NIHL) as they develop skills and perform during instructional activities. Studies using longitudinal dosimeter data show that pedagogical procedures and instructor behaviors are highly predictive of NIHL risk, thus implying the need for innovative approaches to increase instructor competency in managing instructional activities without interfering with artistic and academic freedom. Ambient information systems, an emerging trend in human-computer interaction that infuses psychological behavioral theories into technologies, can help construct informative risk-regulating systems...

Heart-rate variability (HRV) is frequently introduced as mirroring imbalances within the autonomous nerve system. Many investigations are based on the paradigm that increased sympathetic tone is associated with decreased parasympathetic tone and vice versa. But HRV is probably more than an indicator for probable disturbances in the autonomous system. Some perturbations trigger not reciprocal, but parallel changes of vagal and sympathetic nerve activity. HRV has also been considered as a surrogate parameter of the complex interaction between brain and cardiovascular system...

BACKGROUND: Patients who have granulomatosis with polyangiitis (GPA, syn. M. Wegener) often develop an external nose deformity which may have devastating psychological effects. Therefore, reconstruction of nasal deformities by rhinoplasty may become necessary to achieve a normal appearance. OBJECTIVE OF REVIEW: The aim of this systematic review was to investigate the efficacy and safety of surgical reconstruction in external nasal deformities and septal perforation in GPA patients...

Although William James never again reprised his lectures on psychology for teachers at Harvard, he spent most of the 1890s presenting them throughout the country. For all his complaints about them, this was a fine source of income and he used the opportunity to revise and refine them over the rest of the decade. By the end of the 1890s, he was prepared to put the talks down in book form, and turned to his long-time publisher, Henry Holt. The two men first became acquainted with each other when James agreed to write a volume for Holt's American Science series...

RATIONALE: Supplemental oxygen is prescribed to patients with pulmonary fibrosis to normalize oxygen saturations, decrease symptoms and improve quality of life. Along with potential benefits, patients face challenges as they incorporate oxygen into their lives. OBJECTIVE: Our aim was to better understand the perceptions and experiences of patients with pulmonary fibrosis as they confronted the possibility and realities of using supplemental oxygen. METHODS: We performed a mixed-methods study in which we conducted a series of four structured telephone interviews with five patients with pulmonary fibrosis enrolled in a longitudinal observational study...

Preventative psychological interventions to aid women after traumatic childbirth are needed. This proof-of-principle randomized controlled study evaluated whether the number of intrusive traumatic memories mothers experience after emergency caesarean section (ECS) could be reduced by a brief cognitive intervention. 56 women after ECS were randomized to one of two parallel groups in a 1:1 ratio: intervention (usual care plus cognitive task procedure) or control (usual care). The intervention group engaged in a visuospatial task (computer-game 'Tetris' via a handheld gaming device) for 15 min within six hours following their ECS...

Heart rate (HR) and electrodermal activity (EDA) are often used as physiological measures of psychological arousal in various neuropsychology experiments. In this exploratory study, we analyze HR and EDA data collected from four participants, each with a history of suicidal tendencies, during a cognitive task known as the Paced Auditory Serial Addition Test (PASAT). A central aim of this investigation is to guide future research by assessing heterogeneity in the population of individuals with suicidal tendencies...

Psychophysiological interaction (PPI) is a widely used regression-based method to study connectivity changes in different experimental conditions. A PPI effect is generated by point-by-point multiplication of a psychological variable (experimental design) and a physiological variable (time series of a seed region). If the psychological variable is non-centered with a constant component, the constant component will add a physiological variable to the PPI term. The physiological component would in theory be accounted for by the physiological main effect in the model...

In the Kuwait context, from January 1991 to December 1991, there were a series of chemical and psychological Gulf War-era exposures that left persistent, long-term damage. Extreme stress from a critical event speeds up the usual disease latency period, and may be part of a synergistic effect that leads to higher disease rates over a shorter period of time. I am interested in the impact of armed conflict on health outcomes over the life course in Kuwait, and particularly the pathways through which armed conflict causes changes in health on a population level...

Recent work has highlighted that process-outcome relationships are likely to vary depending on the client, yet there is little direct evidence regarding specific intervention effects in individual clients. This study attempted to address the hypothesis that some clients reveal more than others regarding the impact of specific interventions. Intensive case study analyses were applied to 2 clients with principal major depressive disorder and comorbid anxiety disorders receiving transdiagnostic psychotherapy. Clients completed a battery of symptom and psychological assessments of mindfulness, cognitive reappraisal use, and emotion avoidance on many occasions throughout treatment...

BACKGROUND: Maltreatment of older people (elder abuse) includes psychological, physical, sexual abuse, neglect and financial exploitation. Evidence suggests that 10% of older adults experience some form of abuse, and only a fraction of cases are actually reported or referred to social services agencies. Elder abuse is associated with significant morbidity and premature mortality. Numerous interventions have been implemented to address the issue of elder maltreatment. It is, however, unclear which interventions best serve to prevent or reduce elder abuse...

We introduce a novel method for delineating context-dependent functional brain networks whose connectivity dynamics are synchronized with the occurrence of a specific psychophysiological process of interest. In this method of context-related network dynamics analysis (CRNDA), a continuous psychophysiological index serves as a reference for clustering the whole-brain into functional networks. We applied CRNDA to fMRI data recorded during the viewing of a sadness-inducing film clip. The method reliably demarcated networks in which temporal patterns of connectivity related to the time series of reported emotional intensity...

BACKGROUND: The importance of supportive social relationships for psychological well-being has been previously recognized, but the direction of associations between both dimensions and how they evolve when adolescents enter adulthood have scarcely been addressed. The present study aims to examine the gender-specific associations between self-reported friendship network quality and psychological well-being of young people during the transition from late adolescence to young adulthood by taking into account the direction of association...
