Predicting mental health treatment outcomes using latent growth mixture models and machine learning in a real-world clinical setting.

Previous models of depression outcomes have been limited by symptom heterogeneity within populations. This study conducted a retrospective analysis using latent growth mixture models to identify heterogeneous trajectories within a clinical population, subsequently developing machine learning models to predict clinical outcomes based on baseline characteristics and symptom measures. The study analyzed approximately 15,000 clients aged 18-89 in a real-world clinical setting, treated for up to 180-days between 2015 and 2020.

Comparison of telehealth and in-person mental health care in military veterans and active-duty service members.

Telehealth services are increasingly utilized to improve mental health care access for active-duty service members (ADSM) and military veterans. This article examines mental health outcomes for veterans ( = 4,536) and ADSMs ( = 378) who met diagnostic criteria for depression, posttraumatic stress disorder, or generalized anxiety disorder ( = 4,914) and were treated at Cohen Veterans Network Clinics using either telehealth or in-person treatment modalities. Results demonstrate small but statistically significant advantages for telehealth in terms of discharge scores, rates of clinically significant change, and efficiency of treatment.

Change in Event Centrality and Posttraumatic Stress Disorder Symptoms During Intensive Treatment.

Event centrality, defined as the extent to which a traumatic event becomes a core component of a person's identity (Berntsen & Rubin, 2006), is both a correlate and predictor of posttraumatic stress disorder (PTSD) symptoms, over and above event severity. These findings suggest that decreasing the perceived centrality of a traumatic event to one's identity might result in decreases in PTSD symptom severity. To date, few studies have examined how centrality is affected by PTSD treatment.

A test of a resilience based intervention for mental health problems in Iraqi internally displaced person camps.

The mental health needs of those in internally displaced persons camps are significant and are compounded by a number of barriers to care. Traditional methods of mental health care are often not feasible and thus a need exists for interventions that can successfully meet these conditions. The current study introduces and tests a new positive-psychology intervention, GROW, which was designed specifically for use in internally displaced persons camps.

Blurred boundaries between Pro-Anorexia and Fitspiration media? Diverging cognitive and emotional effects.

Social media is an emerging source of body-focused messages affecting young women. This research investigated the diverging cognitive and emotional effects of Pro-Anorexia (Pro-Ana) and Fitspiration content using linguistic analysis. Undergraduate college women ( = 129) viewed one of six experimentally-created blogs: text or images of Fitspiration, Pro-Ana, or control (Home Décor) and completed an open-ended prompt with their reaction.

Moral decision making, religious strain, and the experience of moral injury.

Objective: Moral injury is the lasting psychological, spiritual, and behavioral effects of having perpetrated acts that transgress moral boundaries. Contemporary models of moral injury in military veterans examine the role of transgressive acts, moral appraisals of these acts, and the symptoms of moral injury. However, little research has examined potential pathways between these elements.

Measures of morally injurious experiences: A quantitative comparison.

A recent body of literature has examined the psychological effects of perpetrating or failing to prevent acts that violate one's sense of right and wrong. The objective of this study was to examine and compare correlations between the two most widely used instruments measuring this construct in a sample of military veterans and relevant psychosocial variables. Individuals (N = 182) who reported military combat experience completed the Moral Injury Events Scale and the Moral Injury Questionnaire-Military Version, along with measures of combat exposure, depression, posttraumatic stress disorder, alcohol concerns, anger, guilt, and shame.

Negative outcomes after morally injurious experiences: A replication and extension.

Objective: The current study replicates and extends a model of the relationship between morally injurious experiences, moral emotions, and posttraumatic stress disorder (PTSD; Jordan, Eisen, Bolton, Nash, & Litz, 2017). The current study builds on this earlier work by including broader measures of moral emotions and by including an assessment of symptoms of depression.

Method: An online survey, distributed using crowdsourcing software, was completed by 161 military veterans.

An Integrated Model of Posttraumatic Stress and Growth.

A number of recent models have examined cognitive predictors of posttraumatic stress and posttraumatic growth (S. Barton, A. Boals, & L.

Monitoring of an esterification reaction by on-line direct liquid sampling mass spectrometry and in-line mid infrared spectrometry with an attenuated total reflectance probe.

A specially designed thermal vaporiser was used with a process mass spectrometer designed for gas analysis to monitor the esterification of butan-1-ol and acetic anhydride. The reaction was conducted at two scales: in a 150 mL flask and a 1L jacketed batch reactor, with liquid delivery flow rates to the vaporiser of 0.1 and 1.

Longitudinal predictors of desire to re-enlist in the military among male and female national guard soldiers.

Given the cost and burden associated with training and recruitment of military members, identifying predictors of military retention remains an important goal. The aim of the current study was to examine predictors of male and female service members' likelihood of remaining in the National Guard following combat deployment in support of Operation Iraqi Freedom. Using a prospective, longitudinal design, this study assessed a wide range of predictors including mental health functioning, personality variables, deployment stressors, and various domains of quality of life.

Confirmatory factor and measurement invariance analyses of the emotion regulation questionnaire.

Emotion regulation is widely studied in many areas of psychology and the number of publications on emotion regulation has increased exponentially over the past few decades. Additionally, interest in the relationships between emotion dysregulation processes and psychopathology has drastically increased in recent years. The Emotion Regulation Questionnaire (ERQ) was developed to measure two specific constructs related to emotion control: reappraisal and suppression (Gross & John, 2003).

Path analytic examination of a cognitive model of PTSD.

Ehlers and Clark (2000) developed a cognitive model of posttraumatic stress disorder (PTSD) symptom maintenance which implicated the role of posttraumatic cognitions and aspects of the trauma memory in maintaining symptoms via an increased sense of current threat. The aim of the current study was to empirically test a variant of this model using path analysis. Participants in the current study were 514 undergraduates at a midwestern university who reported experiencing at least one traumatic event.

Social anxiety across ethnicity: a confirmatory factor analysis of the FNE and SAD.

Previous research has established that social anxiety occurs at different rates in African American and European American populations (Grant et al., 2005), while psychometric investigations of widely used measures of psychopathology show differences in factor structure based on ethnic background (Carter, Miller, Sbrocco, Suchday, & Lewis, 1999; Chapman, Williams, Mast, & Woodruff-Borden, 2009). The current study examined response characteristics of 1276 African American and European American undergraduates completing the Fear of Negative Evaluation and Social Avoidance and Distress Scales (Watson & Friend, 1969).

An examination of the differential effects of the experience of DSM-IV defined traumatic events and life stressors.

Recent evidence suggests that individuals exposed to traumatic events report similar, if not lower, levels of posttraumatic stress disorder (PTSD) symptoms than individuals exposed to nontraumatic stressful life events [J. Anxiety Disord. 19 (2005) 687-698; Br.

A factor analytic comparison of five models of PTSD symptoms.

This study examined the factor structure of PTSD symptoms in a sample of college students (n=344) reporting exposure to a range of traumatic events. The sample was randomly split and an exploratory factor analysis was conducted with half of the sample. The factor structure obtained in the exploratory analysis was evaluated against three other models using confirmatory factor analysis utilizing the second half of the sample.
