Long-duration spaceflight impacts human physiology, including well documented immune system dysregulation. The space food system has the potential to serve as a countermeasure to maladaptive physiological changes during spaceflight. However, the relationship between dietary requirements, the food system, and spaceflight adaptation requires further...
The Artificial Gravity Bed Rest with European Space Agency (AGBRESA) study involved 2 campaigns of 60-day bed rest at 6° head down tilt in the:envihab facility in Cologne, Germany, in 2019. The objective was to determine whether centrifugation of supine subjects mitigates physiological changes that occur due to the exposure to the spaceflight analo...
Long-duration space exploration missions will pose significant risks to the physical and behavioral health and performance of the crew. We documented the presence and frequency of (1) behavioral health and performance (BHP)-relevant symptoms for each condition in NASA's Exploration Medical Conditions List (EMCL), (2) the BHP-relevant effects of app...
Objective: Complete prenatal cerebellar infarction is rare and few reports exist documenting developmental outcomes. We report outcome data on a child who sustained a stroke to the bilateral cerebellar hemispheres at 25 weeks gestation, and was subsequently seen for follow-up neuropsychological evaluations at ages 5 years, 5 months and 7 years, 9 m...
Introduction:
Caring for children with oncological and hematological disorders may lead to caregiver emotional distress and caregiver burden; however, little work has examined the relationship between children's symptoms and caregiver's distress and burden.
Method:
This study used self-report survey data from caregivers (N = 96) and a cross-sect...
A paucity of research on thought suppression exists among adolescents. The present study describes the preliminary psychometrics of the Adolescent Thought Control Questionnaire (TCQ-A) and its relationships with internalizing symptomatology in adolescents. Adolescents between 12 and 18 years of age completed the TCQ-A and other self-report instrume...
Intolerance of uncertainty (IU) is thought to underlie several internalizing disorders; however, it has only begun to be explored within social anxiety (SA). This study extends previous findings by examining IU's relation to performance and interaction SA subtypes and by accounting for obsessive-compulsive symptoms.
A total of 472 undergraduates co...
Social phobia is a frequent co-occurring diagnosis with obsessive-compulsive disorder (OCD); however, co-occurring OCD in those with social phobia is less common. Genetic, environmental, and cognitive traits are common risk factors for anxiety disorders broadly. It is plausible that shared variables related to OCD and/or social phobia could provide...
Background:
Intolerance of uncertainty (IU) and perfectionism have both been shown to predict severity of obsessive-compulsive disorder (OCD) symptoms in populations diagnosed with OCD, as well as analogue samples. According to cognitive models of OCD, symptoms are maintained by dysfunctional beliefs including IU and perfectionism. The purpose of...
There is a scarcity of research looking at how comorbid psychological disorders impact the assessment of children with autism spectrum disorders (ASD). The present study aimed to extend the literature in this area by evaluating rates of comorbid symptoms in both children with ASD and those with attention-deficit/hyperactivity disorder (ADHD). Child...
This study (n = 304) examined the relationship between somatic symptoms and social anxiety. Significant differences in the experience of somatic symptoms were found among four groups (i.e. performance anxious, interaction anxious, generalized socially anxious, and controls). Post hoc analyses revealed that those who exceeded the clinical cutoff for...
Behavioral avoidance tasks (BATs) have been used for decades in the assessment of specific phobias, but they also involve a number of prohibitive difficulties. This study investigated a new imaginal/self-report instrument, the Behavioral Avoidance Task Using Imaginal Exposure (BATIE), and evaluated whether it was an efficient paper-and-pencil alter...
Autism spectrum disorders (ASD) have been shown to be highly comorbid with other psychological disorders. Currently, there is a dearth of research examining how comorbidity impacts the assessment of core symptoms and co-occurring problem behaviors in children with ASD. The present study evaluated the rates of comorbid symptoms in children with ASD...
Objective:
Investigated the use of a combined scale (Worry/Depressed and Avoidant scales) from the Autism Spectrum Disorders-Comorbidity for Children (ASD-CC) as a measure of anxiety. Alternative methods of measuring anxiety were examined using the ASD-CC in an ASD population.
Methods:
Participants included 147 children, age 2-16 years, evincing...
To inspect the presence and severity of deficits in restricted and/or repetitive behaviours and interests (RRBIs) in children with cerebral palsy (CP) and autism spectrum disorders (ASDs).
Children studied (18-35 months of age) belonged to one of three diagnostic groups: children with CP and autism (n = 11), children with CP and Pervasive Developme...
Unfortunately, childhood anxiety disorders are prevalent and cause a great deal of difficulty and interference in the lives of those children affected. The following chapter provides a brief overview of the outcome of almost two decades of research into the development and dissemination of efficacious treatments to alleviate the symptoms of these a...
Research on treatments for childhood anxiety disorders has increased greatly in recent decades. As a result, it has become increasingly necessary to synthesize the findings of these treatment studies into reviews in order to draw wider conclusions on the efficacy of treatments for childhood anxiety. Previous reviews of this literature have used var...
This study evaluated the effectiveness and treatment costs associated with a stepped care protocol of exposure and response prevention (EX/RP) for obsessive-compulsive disorder (OCD). In the current open trial, patients (N=14) began with self-directed EX/RP and minimal therapist guidance over the course of six weeks (Step 1). During this phase of t...
The following multiple baseline case series examines school refusal behavior in 4 male adolescents. School refusal symptom presentation was ascertained utilizing a functional analysis from the School Refusal Assessment Scale (Kearney, 2002). For the majority of cases, treatment was conducted within a 15-session intensive format over a 3-week period...
