Trauma characteristics, post-traumatic symptoms, psychiatric disorders and suicidal behaviours: Results from the 2007 Australian National Survey of Mental Health and Wellbeing

Objective: The current study examined whether trauma characteristics such as the type and number of traumatic events were associated with three suicidal behaviours (i.e. ideation, plan and attempt) after adjusting for sociodemographic factors, post-traumatic symptoms and history of psychiatric disorders. Method: Data came from the 2007 Australian National Survey of Mental Health and Wellbeing (N = 8841). Respondents were asked about exposure to 28 traumatic events that occurred during their lifetime.

The classification of body dysmorphic disorder symptoms in male and female adolescents

Background Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created ‘obsessive-compulsive and related disorders’ chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models.

Therapeutic Alliance, Client Need for Approval, and Perfectionism as Differential Moderators of Response to eHealth and Traditionally Delivered Treatments for Comorbid Depression and Substance Use Problems

Purpose: This study sought to undertake an exploratory analysis of the impact of therapeutic alliance and dysfunctional attitudes (perfectionism and need for approval) on outcomes for participants receiving therapist-delivered and eHealth interventions for comorbid depression and alcohol/cannabis use problems. These factors have been shown in previous research to moderate response to psychological treatment for depression and related disorders.

The general relationship between internalizing psychopathology and chronic physical health conditions: a population-based study

Studies have consistently demonstrated a reciprocal relationship between internalizing disorders and several chronic physical health conditions. Yet, much of the extant literature fails to take into account the role of comorbidity among internalizing disorders when examining the relationship with poor physical health.

Associations of objective and subjective sleep disturbance with cognitive function in older men with comorbid depression and insomnia

To examine whether poor objective and subjective sleep quality are differentially associated with cognitive function. Participants were recruited from primary and secondary care, and directly from the community, in Sydney, Australia. The sample consisted of 74 men 50. years and older (mean [SD], 58.4 [6.2] years), with comorbid depression and above-threshold insomnia symptoms, participating in a trial of online cognitive behavioral therapy for insomnia.

A Network Approach to Modeling Comorbid Internalizing and Alcohol Use Disorders

Internalizing disorders co-occur with alcohol use disorder (AUD) at a rate that exceeds chance and compromise conventional AUD treatment. The "vicious cycle" model of comorbidity specifies drinking to cope (DTC) as a link between these disorders that, when not directly addressed, undermines the effectiveness of conventional treatments. Interventions based on this model have proven successful but there is no direct evidence for how and to what extent DTC contributes to the maintenance of comorbidity.

Conduct Disorder and Alcohol Use Disorder Trajectories, Predictors, and Outcomes for Indigenous Youth

Objective: The aim of this study was to identify separate and joint trajectories of conduct disorder (CD) and alcohol use disorder (AUD) . DSM-IV diagnostic symptoms among American Indian and First Nation (Indigenous) youth aged 10 to 18 years, and to characterize baseline profiles and later outcomes associated with joint trajectory group membership.


Network approach to the symptom-level association between alcohol use disorder and posttraumatic stress disorder

Purpose: The high prevalence of alcohol use disorder among individuals with a history of trauma and posttraumatic stress disorder is well documented. The current study applied network analysis to map the structure of symptom associations between these disorders.


Unique Associations between Childhood Temperament Characteristics and Subsequent Psychopathology Symptom Trajectories from Childhood to Early Adolescence

Existing research suggests that temperamental traits that emerge early in childhood may have utility for early detection and intervention for common mental disorders. The present study examined the unique relationships between the temperament characteristics of reactivity, approach-sociability, and persistence in early childhood and subsequent symptom trajectories of psychopathology (depression, anxiety, conduct disorder, and attention-deficit hyperactivity disorder; ADHD) from childhood to early adolescence.
