Common Genetic and Environmental Contributions to Anxiety Sensitivity, Anxiety, and Cognitive Symptoms of Eating Disorders in Adolescence.

Anxiety sensitivity may be associated with both anxiety and eating disorder symptoms, which could contribute to the frequent comorbidity of both syndromes. This study examined the common (i.e.

Temporal relations between alcohol use, posttraumatic stress disorder, and internalizing symptoms during the COVID-19 pandemic: An ecological momentary assessment investigation.

Objective: COVID-19 is a collective stressor associated with both increased mental health symptoms and increased frequency of alcohol use. These increases highlight the need for investigations into the functional relationships between traumatic stress symptoms and alcohol use in the wake of the pandemic. This study sought to use ecological momentary assessment to examine the temporal association of posttraumatic stress disorder (PTSD) with alcohol use during the COVID-19 pandemic.

Rumination, but not mood, predicts prospective memory performance: novel insights from a derived measure of trait rumination.

Prospective memory (PM) is the accurate execution of an intention in the future. PM may be negatively impacted by negative affect, but the underlying mechanisms remain unclear. Rumination may increase the frequency of task-irrelevant thoughts, which deplete attentional capacity and reduce performance.

A prospective longitudinal study of depression, perceived stress, and perceived control in resettled Syrian refugees' mental health and psychosocial adaptation.

This prospective study examined the psychosocial adaptation of a community sample of newly resettled Syrian refugees in Canada ( = 235). Specifically, depressive symptoms, perceived stress, and perceived control were collected in Arabic at baseline and 1-year follow-up. Two theory-informed, cross-lagged panel models demonstrated that higher baseline depressive symptoms predicted lower perceived self-efficacy and lower perceived control at 1-year follow-up.

Symptoms of borderline personality and related pathologies behave as temporal and contemporaneous networks.

In contrast to latent variable models suggesting a common etiology, network theory proposes that symptoms of psychopathology co-occur because of direct, dynamic associations among them. We examined how symptoms associated with borderline personality disorder, depression, and anxiety mutually reinforce one another over time, forming a network. We further identified symptoms that drove the network by exerting the most influence on other symptoms.

Monthly correlates of longitudinal child mental health during the COVID-19 pandemic according to children and caregivers.

Multiple reviews identify the broad, pervasive initial impact of the global COVID-19 pandemic on the mental health of children, who may be particularly vulnerable to long-term psychiatric sequelae of the ongoing pandemic. However, limited longitudinal research examines persistence of, or change in, children's distress or psychiatric symptomatology. From June 2020 through December 2021, we enrolled two cohorts of families of children aged 8-13 from Southwestern Ontario into a staggered baseline, longitudinal design that leveraged multi-informant report (N = 317 families).

Brief App-Based Cognitive Behavioral Therapy for Anxiety Symptoms in Psychiatric Inpatients: Feasibility Randomized Controlled Trial.

Background: Psychiatric inpatients often have limited access to psychotherapeutic education or skills for managing anxiety, a common transdiagnostic concern in severe and acute mental illness. COVID-19-related restrictions further limited access to therapy groups on inpatient psychiatric units. App-based interventions may improve access, but evidence supporting the feasibility of their use, acceptability, and effectiveness in psychiatric inpatient settings is limited.

Self-critical perfectionism, dependency and entropy during cognitive behavioural therapy for depression.

Objectives: This study examined whether 'personality vulnerability' (i.e., self-critical perfectionism or dependency) predicts the trajectory of change, as well as variability and instability (i.

Adolescent pain: appraisal of the construct and trajectory prediction-by-symptom between age 12 and 17 years in a Canadian twin birth cohort.

Adolescent pain is common and continues into adulthood, leading to negative long-term outcomes including substance-related morbidity: an empirical definition of its construct may inform the early detection of persistent pain trajectories. These secondary analyses of a classical twin study assessed whether headaches, back pains, abdominal pain, chest pains, stabbing/throbbing pain, and gastric pain/nausea, measured in 501 pairs across 5 waves between age 12 and 17 years, fit a unitary construct or constitute independent manifestations. We then assessed which symptoms were associated with a steady, "frequent pain" trajectory that is associated with risk for early opioid prescriptions.

Alternative model of personality disorders traits predict residential addictions treatment completion.

Background: Among people receiving residential treatment for a substance use disorder (SUD), premature treatment termination predicts poor post-treatment outcomes. We examined the utility of the alternative model for personality disorders (AMPD) for predicting premature residential SUD treatment termination, including interactions with age and gender.

Methods: Participants (N = 374) were receiving residential treatment for SUD and enrolled in a clinical trial with two conditions: Skills for Improving Distress Intolerance (SIDI) and Supportive Counseling (NCT01741415).

Children's Mental Health in Southwestern Ontario during Summer 2020 of the COVID-19 Pandemic.

Objective: COVID-19 presents an unprecedented global crisis. Research is critically needed to identify the impact of the pandemic on children's mental health including psychosocial factors that predict resilience, recovery, and persistent distress. The present study collected data in June-July 2020 to describe children's mental health during the initial phase of the pandemic, including the magnitude and nature of psychiatric and psychological distress in children, and to evaluate social support as a putative psychosocial moderator of children's increased distress.

Pediatric anxiety associated with altered facial emotion recognition.

Multiple psychiatric disorders are associated with difficulties in facial emotion recognition. However, generalized anxiety disorder may be associated with more accurate recognition of others' emotional expressions, particularly expressions of happiness and fear, which index safety and threat. Children aged 9-14 from a community sample (N = 601) completed a facial emotion labeling task.

Intraindividual association of PTSD symptoms with binge drinking among trauma-exposed students.

People, particularly undergraduate students, who report elevated symptoms of posttraumatic stress disorder (PTSD) are at elevated risk of binge drinking. The present study used ecological momentary assessment to (a) evaluate whether PTSD severity, specifically, or psychological distress, generally, are associated with binge drinking and (b) examine the self-medication and susceptibility models of the comorbidity of PTSD with binge drinking while accounting for shared liability (i.e.

Emotional and interpersonal mechanisms in community SSRI treatment of social anxiety disorder.

Background: Affective and interpersonal behavioural patterns characteristic of social anxiety disorder show improvement during treatment with serotonin agonists (e.g., selective serotonin reuptake inhibitors), commonly used in the treatment of social anxiety disorder.

Model Fit Estimation for Multilevel Structural Equation Models.

Structural equation modeling (SEM) provides an extensive toolbox to analyze the multivariate interrelations of directly observed variables and latent constructs. Multilevel SEM integrates mixed effects to examine the covariances between observed and latent variables across many levels of analysis. However, while it is necessary to consider model fit, traditional indices are largely insufficient to analyze model fit at each level of analysis.

Genetic and Environmental Predictors of Adolescent PTSD Symptom Trajectories Following a Natural Disaster.

Genes, environmental factors, and their interplay affect posttrauma symptoms. Although environmental predictors of the longitudinal course of posttraumatic stress disorder (PTSD) symptoms are documented, there remains a need to incorporate genetic risk into these models, especially in youth who are underrepresented in genetic studies. In an epidemiologic sample tornado-exposed adolescents ( = 707, 51% female, = 14.

Differential Associations of Distress Tolerance and Anxiety Sensitivity With Adolescent Internalizing Psychopathology.

Distress tolerance and anxiety sensitivity may differentiate among internalizing disorders, though few studies have examined differential associations of distress tolerance and anxiety sensitivity with depression and anxiety symptoms while adjusting for their intercorrelation. In an adolescent genetic epidemiological sample (ages 15-21), the present study ( = 848, 56.97% female) examined concurrent associations of distress tolerance and anxiety sensitivity with internalizing psychopathology (i.

Genetic underpinnings of callous-unemotional traits and emotion recognition in children, adolescents, and emerging adults.

Background: Callous-Unemotional (CU) and psychopathic traits are consistently associated with impaired recognition of others' emotions, specifically fear and sadness. However, no studies have examined whether the association between CU traits and emotion recognition deficits is due primarily to genetic or environmental factors.

Methods: The current study used data from 607 Caucasian twin pairs (N = 1,214 twins) to examine the phenotypic and genetic relationship between the Inventory of Callous-Unemotional Traits (ICU) and facial emotion recognition assessed via the laboratory-based Facial Expression Labeling Task (FELT).

A Multimodal Study of Childhood Trauma and Distress Tolerance in Young Adulthood.

Individuals with a history of childhood trauma experience deficits in emotion regulation. However, few studies have investigated childhood trauma and both perceived (i.e.

A Developmental Twin Study of Emotion Recognition and Its Negative Affective Clinical Correlates.

Objective: Youth with psychiatric disorders distinguished by irritability, including depression and associated trait neuroticism, show deficits in the ability to recognize facial expressions of emotion, particularly happiness. However, the contribution of genetic and environmental factors to this ability remains unknown. The present study examined this trait in twins to assess the genetic and environmental influences on face-emotion recognition abilities and their association with irritability, neuroticism, and depression.

Examination of Racial Differences in a Posttraumatic Stress Disorder Group Therapy Program for Veterans.

Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health diagnoses for veterans. Group therapy can be an effective and efficient means of treating PTSD, yet the literature exploring treatment outcomes for racial minorities is mixed and limited. The present study was an evaluation across racial groups of the PTSD Recovery Program, a manualized group therapy implemented at a Veterans Affairs hospital.

Adaptive Equilibrium Regulation: Modeling Individual Dynamics on Multiple Timescales.

Damped Linear Oscillators estimated by 2nd-order Latent Differential Equation have assumed a constant equilibrium and one oscillatory component. Lower-frequency oscillations may come from seasonal background processes, which non-randomly contribute to deviation from equilibrium at each occasion and confound estimation of dynamics over shorter timescales. Boker (2015) proposed a model of individual change on multiple timescales, but implementation, simulation, and applications to data have not been demonstrated.

A Population-Based Twin Study of Childhood Irritability and Internalizing Syndromes.

Childhood irritability exhibits significant theoretical and empirical associations with depression and anxiety syndromes. The current study used the twin design to parse genetic and environmental contributions to these relationships. Children ages 9-14 from 374 twin pairs were assessed for irritability and symptoms of depression, generalized anxiety, panic, social phobia, and separation anxiety using dimensional self-report instruments.
