The impact of item order on the factor structure of the PTSD Checklist for DSM-5.

The PTSD Checklist for DSM-5 (PCL-5) is the most widely used self-report measure of posttraumatic stress disorder (PTSD) and is frequently modeled as having four correlated factors consistent with the DSM-5 symptom structure. Some researchers have argued that item order may influence factor structure. Although two studies have examined this, they were both based on DSM-IV criteria, and neither utilized a randomized design.

Massed written exposure therapy delivered to veterans with posttraumatic stress symptoms on an acute inpatient mental health unit.

Written exposure therapy (WET) is a brief, manualized trauma-focused treatment typically delivered in five individual weekly sessions. Given the brevity and effectiveness of WET, researchers have begun to focus on its delivery in a massed format. However, only one case study examining massed delivery has been published to date.

Aza-Cibalackrot: Turning on Singlet Fission Through Crystal Engineering.

Singlet fission is a photophysical process that provides a pathway for more efficient harvesting of solar energy in photovoltaic devices. The design of singlet fission candidates is non-trivial and requires careful optimization of two key criteria: (1) correct energetic alignment and (2) appropriate intermolecular coupling. Meanwhile, this optimization must not come at the cost of molecular stability or feasibility for device applications.

Acceptability, feasibility, and utility of a safety aid reduction treatment in underserved veterans: a pilot investigation.

Access to mental health services, particularly for veterans residing in underserved communities, remain scarce. One approach to addressing availability barriers is through the use of group-based transdiagnostic or unified treatment protocols. One such protocol, Safety Aid Reduction Treatment (START), previously termed False Safety Behavior Elimination Treatment (FSET), has received increasing empirical support.

Racism in Australia: a protocol for a systematic review and meta-analysis.

Background: Racism has been identified as a major source of injustice and a health burden in Australia and across the world. Despite the surge in Australian quantitative research on the topic, and the increasing recognition of the prevalence and impact of racism in Australian society, the collective evidence base has yet to be comprehensively reviewed or meta-analysed. This protocol describes the first systematic review and meta-analysis of racism in Australia at the national level, focussing on quantitative studies.

Posttraumatic stress and substance use among military veterans: Associations with distress intolerance and anxiety sensitivity.

The co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUD) is highly prevalent among military veterans and represents a difficult-to-treat comorbidity. Distress intolerance (DI; i.e.

Magnetic sensitivity of cryptochrome 4 from a migratory songbird.

Night-migratory songbirds are remarkably proficient navigators. Flying alone and often over great distances, they use various directional cues including, crucially, a light-dependent magnetic compass. The mechanism of this compass has been suggested to rely on the quantum spin dynamics of photoinduced radical pairs in cryptochrome flavoproteins located in the retinas of the birds.

Benefits and Risks: A Systematic Review of Information and Communication Technology Use by Autistic People.

Background: Communication via the internet is a regular feature of everyday interactions for most people, including autistic people. Researchers have investigated how autistic people use information and communication technology (ICT) since the early 2000s. However, no systematic review has been conducted to summarize findings.

Anxiety sensitivity and substance use: Differential levels across individuals primarily using opioids, cannabis, or stimulants.

Background: The purpose of the current study was to compare levels of anxiety sensitivity (AS) across a treatment-seeking sample of individuals primarily using opioids, stimulants, or cannabis. Consistent with the idea that individuals high in AS may be motivated to use substances with real or perceived anxiolytic properties, it was hypothesized that individuals primarily using opioids or cannabis would evidence higher levels of AS compared to individuals primarily using stimulants.

Methods: The sample consisted of 110 veterans (including 29 individuals primarily using opioids, 42 primarily using cannabis, and 39 primarily using stimulants) presenting for psychological services to a Posttraumatic Stress Disorder (PTSD) and Substance Use Disorder (SUD) specialty clinic at a large southeastern Veteran Affairs (VA) hospital.

Social Capital and Autism in Young Adulthood: Applying Social Network Methods to Measure the Social Capital of Autistic Young Adults.

Social isolation is a core challenge associated with autism. Interpersonal relationships and the resources and support embedded in the social networks of autistic young adults could impact key adult outcomes, including quality of life, mental health, employment, and independence. However, little research systematically measures the networks of autistic young adults and network impact on key adult outcomes.

Intolerance of uncertainty and DSM-5 PTSD symptoms: Associations among a treatment seeking veteran sample.

Intolerance of uncertainty (IU), defined as an inability to tolerate the unpleasant response triggered by the observed absence of information, has received increased empirical attention in recent years. The contribution of this cognitive behavioral construct to the etiology and maintenance of various anxiety disorders has become increasingly recognized. However, the relationship between IU and other affective disorders, including posttraumatic stress disorder (PTSD), remains largely unexplored.

Using a Clinician-Administered Interview to Examine the Overlap in Posttraumatic Stress Disorder Criteria D and E.

Although the diagnosis of posttraumatic stress disorder (PTSD) is often criticized for including symptoms that overlap with one another, only one study has explored the impact of symptom reporting. Using a clinician-rated interview for PTSD (N = 558), the current study examined overlap between PTSD criteria D1, D2, and D3 ("target D symptoms") and criterion E symptoms of similar content (i.e.

Examining various subthreshold definitions of PTSD using the Clinician Administered PTSD Scale for DSM-5.

Background: The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5; American Psychiatric Association [APA], 2013) includes Other- and Unspecified- Trauma and Stressor-Related Disorders to capture subthreshold Posttraumatic Stress Disorder (PTSD) symptoms. However, the DSM-5 does not specify the number or type of symptoms needed to assign them. The purpose of the current study was to extend our understanding of subthreshold PTSD by comparing four commonly used definitions adapted to the DSM-5 PTSD criteria in an outpatient treatment-seeking sample.

27 ways to meet PTSD: Using the PTSD-checklist for DSM-5 to examine PTSD core criteria.

Posttraumatic stress disorder (PTSD) has been criticized for including symptoms that substantially overlap with other depression and anxiety disorders. To address this concern, Brewin et al. (2009) reformulated the diagnosis around a core symptom set.

The relationship between DSM-5 PTSD symptom clusters and alcohol misuse among military veterans.

Background And Objectives: Prior research has revealed a strong relationship between Posttraumatic Stress Disorder (PTSD) and alcohol misuse. However, previous attempts to understand nuanced associations between PTSD symptom clusters and alcohol misuse within military veteran samples have produced mixed results. In an attempt to better understand the associations between PTSD and alcohol misuse, the current study examined the unique relationships between the newly classified Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) PTSD symptom clusters and alcohol misuse in an outpatient sample of military veterans seeking treatment for PTSD and Substance Use Disorders.

Pilot study comparing telephone to in-person delivery of cognitive-behavioural therapy for trauma-related insomnia for rural veterans.

Introduction It is estimated that 70% of patients with posttraumatic stress disorder (PTSD) have chronic insomnia. A recent meta-analysis examined cognitive-behavioural therapy for insomnia (CBT-I) in veterans with and without PTSD, and suggested that most studies had questionable methodology, but generally supported its effectiveness in this population. Further, while CBT-I via telehealth (i.

Sometimes Less is More: Establishing the Core Symptoms of PTSD.

Historically, the symptoms of posttraumatic stress disorder (PTSD) have garnered attention and controversy due to symptom overlap with other disorders. To improve diagnostic specificity, researchers have proposed to reformulate PTSD symptoms into a parsimonious set of core criteria. The core symptoms consisted of recurrent distressing dreams or flashbacks; internal or external avoidance; and hypervigilance or exaggerated startle.

Associations between lower order anxiety sensitivity dimensions and DSM-5 posttraumatic stress disorder symptoms.

Anxiety sensitivity (AS), a well-established individual difference variable reflecting a tendency to fear bodily sensations associated with arousal, has been implicated in the development and maintenance of posttraumatic stress disorder (PTSD). Despite these associations, little research has examined the relations between AS subfactors (eg physical, cognitive, and social) and PTSD symptoms and none have examined these associations in the context of DSM-5 (Diagnostic Statistical Manual of Mental Disorders, Fifth Edition) PTSD clusters (ie intrusion, avoidance, negative alterations in cognitions/mood, and arousal). Participants included 50 veterans presenting to an outpatient Veteran Affairs Clinic for psychological services.

Examining potential overlap of DSM-5 PTSD criteria D and E.

The Diagnostic and Statistical Manual, Fifth Edition-5 (DSM-5) has adopted a four-factor symptom model for Posttraumatic Stress Disorder (PTSD) that includes new symptom additions in criterion D (D2, D3, D4), negative alterations in cognition and mood. This article examines potential overlapping endorsement of these symptoms amongst one another and with the behavioral symptoms within PTSD criterion E (E1 and E3; alterations in arousal and reactivity), through the lenses of cognitive-behavioral theory. Responses of veteran participants (N=320) completing the PTSD Checklist-5 were used to determine overlap in symptom reporting.

Face to face but not in the same place: A pilot study of prolonged exposure therapy.

This pilot study examined use of smartphone technology to deliver prolonged exposure (PE) therapy to patients with posttraumatic stress disorder (PTSD) with geographic limitations hindering in-person therapy. The primary goal was to examine the feasibility and acceptability of using video teleconferencing (i.e.

Changing stigmatizing perceptions and recollections about mental illness: the effects of NAMI's in Our Own Voice.

In Our Own Voice (IOOV) is a 90-min anti-stigma program that comprises face-to-face stories of challenges of mental illness and hopes and dreams commensurate with recovery. We pared down IOOV to a 30-min version, using information from two focus groups. In this study, effects of 90- versus 30-min IOOV are contrasted with 30 min of education.

What lessons do coming out as gay men or lesbians have for people stigmatized by mental illness?

Goffman (Stigma: Notes on the management of spoiled identity, Prentice-Hall Inc., Englewood Cliffs, NH, 1963) distinguished stigmatized groups as discredited (with relatively obvious marks such as people of color or gender) or discreditable (without obvious marks, causing stigma to be largely hidden). Like gay men and lesbians, people with various mental illnesses can opt to stay in the closet about these conditions in order to avoid corresponding prejudice and discrimination.
