A Preregistered Longitudinal Analysis of Aggressive Video Games and Aggressive Behavior in Chinese Youth Abstract Whether aggressive video games (AVGs) promote aggression in youth remains a matter of debate despite decades of research. Longitudinal studies to date have provided mixed results, with effect sizes, overall, being quite low. However, few longitudinal studies have preregistered their analyses. The current article presents a preregistered analysis of AVG influences on later youth aggression. With several other variables controlled (age, sex, family income, moral disengagement, Time 1 aggression) AVG exposure did not predict Time 2 aggression. Evidence from this sample did not support the common belief that AVG exposure is a risk factor for future aggression in youth.

A Further Test of the Impact of Online Gaming on Psychological Wellbeing and the Role of Play Motivations and Problematic Use Abstract The impact of increased online gaming play time on psychological wellbeing was examined focusing on the Multiplayer Online Battle Arena (MOBA) game genre. This relationship was explored with respect to motivators for playing and resilience factors. A cross-sectional, online questionnaire design was employed with participants (N = 165) to examine the relationship between weekly average hours played and psychological wellbeing. Five previously reported motivators for playing were tested as mediating variables. In addition, exploratory analyses were conducted to determine the moderating effects of self-esteem and self-efficacy on ‘escapist’ gaming and psychological wellbeing. Results revealed a significant correlation with higher levels of play time associated with poorer psychological wellbeing. This relationship was partially mediated by ‘escapist’ motivation. Self-esteem was found to moderate the negative impact of ‘escapist’ gaming on psychological wellbeing. Research and the associated clinical implications are discussed.

Oppositional Defiant Disorder Dimensions: Associations with Traits of the Multidimensional Personality Model among Adults Abstract The occurrence of Oppositional Defiant Disorder (ODD) behaviours among adults has been supported by a proportion of scholars. The current work examines potential ODD dimensions and their associations with the primary personality traits of Tellegen’s [57] multi-dimensional conceptualization during adulthood. Two independent, general community, adult groups [Group 1: N = 214; mean age (SD) = 35.74 (16.60); Group 2: N = 205; mean age (SD) = 29.00 (12.42)] completed the Current Symptom Scale involving the eight ODD criteria. Group 2 additionally addressed the Multidimensional Personality Questionnaire –Brief Form (MPQ-BF). A series of Confirmatory Factor Analyses (CFA) were implemented. The three-dimensional ODD conceptualization of Burke and colleagues [14] referring to “Negative Affect”, “Oppositional Behavior”, and “Antagonistic Behavior” was confirmed. Considering personality traits, valuable associations were revealed between Oppositional Behavior and Aggression, Antagonistic Behavior and Social Potency as well as Harm Avoidance, and finally, Negative Affect and Stress Reaction, as well as Aggression. The dimensionality of ODD behaviours in adulthood and its correspondence with particular personality traits is approached in the context of psychological practice.

Enhancing Access to Psychiatric Care for Posttraumatic Stress Disorder in Veterans with Mild Traumatic Brain Injury through Integrated Services Abstract (i) To describe an integrated model of psychiatric care for the treatment of posttraumatic stress disorder (PTSD) in veterans with mild traumatic brain injury (mTBI). (ii) To evaluate access to and engagement in psychiatric care among veterans with comorbid PTSD and mTBI after implementation of an Integrated Care (IC) model compared to the previous Usual Care (UC). 100 randomly selected charts, 50 from each of UC and IC were reviewed in this non-concurrent case- control study. Polytrauma Network Site (PNS), an outpatient rehabilitation clinic, for veterans who suffered from brain and other traumatic injuries at an urban VA Polytrauma Rehabilitation Center. Veterans receiving treatment for mTBI symptoms by the rehabilitation team were referred for medication management for PTSD to UC and IC. Co-located access to psychiatric care for medication management as part of the interdisciplinary team with the goal of expediting rehabilitation and functional recovery. Number of consults for psychiatric care for medication management scheduled and completed within 30 days, and number of veterans offered, initiating, and completing evidence-based psychotherapies for PTSD in UC compared to IC. After implementation of IC there were significant improvements in timely completion of consults and patient engagement with a psychiatrist. There also were improvements in number of referrals, initiation, and completion of evidence-based psychotherapies for the treatment of PTSD. IC within the PNS shows promise as an effective care model for increasing access and engagement in care for veterans with comorbid PTSD/mTBI. Future research is needed to examine the utility of this model in other sites.

Comparing the Effectiveness of a Guide Booklet to Simulation-Based Training for Management of Acute Agitation Abstract Simulation-based training may be an effective teaching modality for psychiatry residents; however, simulation-based training is an unstudied and underutilized aspect of psychiatry resident training. The objective of this study was to compare the teaching effectiveness of a simulation-based training to reading a resident on-call psychiatry guide booklet in improving the self-confidence and knowledge of residents that is necessary for managing acutely agitated patients. Pre-intervention self-confidence and knowledge were measured for all residents using a Likert scale questionnaire and a clinical vignette questionnaire, respectively. Residents (n = 23) were randomly assigned to either the simulation group (n = 12) or the guide booklet group (n = 11). Residents in the simulation group completed the simulation-based training, and residents in the guide booklet group were instructed to read the corresponding pages of the booklet regarding management of acute agitation. The comparative teaching effectiveness of the guide booklet and simulation-based training was measured with a post-intervention self-confidence questionnaire and a clinical vignette questionnaire. The study spanned approximately one academic year (July 2016– Sept 2017). Residents who participated in the simulation-based training showed significantly greater improvement in self-confidence (simulation median improvement = 1.458 vs. guide median improvement = 0.033, p = 0.002) and knowledge (simulation median improvement = 0.135 vs. guide median improvement = 0.021, p = 0.0124). Simulation-based training was more effective at improving residents’ self-confidence and knowledge compared to the on-call psychiatry booklet for the management of acutely agitated patients. Though simulation is being used in other specialties, it is a very underutilized tool in the field of psychiatry. This finding underscores the potential for simulation-based training in residency programs to improve resident learning.

Losses and Gains of Psychosocial Resources: Effects on Stress Among Women Undergoing Infertility Treatments and Participating in Social Network Systems Abstract This theory-driven study assessed the association between infertility-related stress and perceived losses of psycho-social resources; and the buffering effect of resource gains and type of infertility (primary/secondary) on this relationship, among women who participate in online infertility-related social network systems (SNS). Ninety women participating in infertility-related SNS completed online questionnaires assessing resource losses and gains and stress levels. Results: Resource loss significantly predicted stress (β = .66, p < .001). Resource loss and the number of children were correlated negatively (r = −.22, p < .05). Residency was significantly related to resource loss (r = −.23, p < .05) and perceived stress (r = −.23, p < .05). Israeli participants reported lesser resource loss and lesser perceived stress, compared to participants from other countries. Surprisingly, neither resource gains related to SNS participation nor infertility-type served as moderators in the relationship between resource loss and stress. The association between resource loss and stress supports COR theory formulation of stress etiology. However, while participants noted significant resource gains from use of SNS, these did not buffer the effects of resource loss on stress. Thus, although it may be enticing to turn to SNS for social support, individuals with infertility need to be encouraged to use face-to-face social support too.

Does Change over Time in Delusional Beliefs as Measured with PDI Predict Change over Time in Belief Flexibility Measured with MADS? Abstract Delusional beliefs and their behavioral consequences are predominant symptoms in patients with psychosis and play an important role in the treatment. Delusional beliefs are a multidimensional concept which can be divided into three components: distress, preoccupation and conviction of delusions. These can be measured using Peters delusions inventory (PDI-21). We question, whether changes in delusional beliefs over time during treatment measured with the PDI-21 can predict changes in belief flexibility measured with the Maudsley assessment of delusions schedule (MADS). We used a group of patients from a randomized controlled trial for a cognitive intervention for psychosis or psychotic symptoms. Aside standard treatment for psychosis, half of the patients took part in a group treatment “Michael’s game”. Patients were assessed at baseline (T1), at 3 months (T2), and at 9 months (T3). We measured delusional beliefs using PDI-21 and belief flexibility with the MADS. One hundred seventy-two patients were included in the analysis. We measured a main effect of PDI-21scores on belief flexibility measured with MADS. PDI-21 Conviction scores predicted outcomes for all measured MADS items. Increasing PDI Distress and Preoccupation scores were predictors for being more likely to dismiss beliefs and change conviction. Time itself was a predictor for changing conviction and being able to plan a behavioral experiment. Overall the changes in PDI scores predicted outcomes for belief flexibility measured with MADS items. The PDI-21 could be a simple and effective way to measure progress in treatment on delusional beliefs.

Treatment Rate for Major Depressive Disorder in China: a Meta-Analysis of Epidemiological Studies Abstract Major depressive disorder (MDD) is a common psychiatric disorder in China, but its reported treatment rate varies largely across different studies. The objective of this meta-analysis was to determine the pooled treatment rate for people with MDD in China and its associated factors. Both English (PubMed, Cochrane Library, PsycINFO, Web of Science) and Chinese (Chinese National Knowledge Infrastructure, WanFang and SinoMed) databases were searched from their commencement date to November 13, 2018. Epidemiological studies that reported the treatment rate of MDD were included and synthesized using a random effects model. Fifteen studies covering 609,054 participants were included. The pooled treatment rate for MDD in China was 19.5% (95% CI: 10.7%–28.4%). Among the 15 studies, 9 reported the number of patients who received treatments in psychiatric hospitals with a pooled treatment rate of 5.2% (95% CI: 2.8%–7.5%). Meta-regression found that study quality (β = 0.131, P = 0.028) and male gender (β = 0.006, P = 0.039) were significantly associated with a higher treatment rate for MDD. In China, the treatment rate for MDD, particularly in psychiatric hospitals, was low. Effective public education and increasing access to mental health services will probably increase the number of people seeking and receiving treatment.

Reasons for Emergency Department Use among Patients with Mental Disorders Abstract Disproportionate use of emergency departments (EDs) by patients with mental disorders suggests the need to evaluate factors associated with ED use. Based on the Andersen Behavioral model, this mixed-method study identified the contributions of predisposing, enabling and needs factors in ED use among 328 patients with mental disorders. We hypothesised that ED use for mental health (MH) reasons would be most strongly associated with need factors. The study was conducted in four EDs located in different territories of Quebec (Canada). ED teams assisted with patient recruitment. Participants completed a questionnaire including a qualitative component on reasons for using the ED and assessments of ED and MH services. Data were organised according to the Andersen model, and analysed thematically. ED users were generally single, with low socioeconomic status and inadequate knowledge of MH services (predisposing factors). Most had a regular source of care which facilitated ED referrals (enabling factors); although inadequate access to outpatient care contributed to ED use. Needs factors were the primary motivators in ED use among patients with mental disorders, especially self-rated importance of problems, and MH diagnoses including suicidal ideation/attempts, depression, anxiety, and substance use disorders. Results confirmed our hypothesis that ED visits were more strongly related to needs factors. The mixed methodology reinforced the importance of predisposing and enabling factors in ED use, particularly in more complex cases. Various strategies (e.g. shared care, recruitment of addiction liaison nurses for SUD screening) are suggested for improving access to other resources and reducing non-urgent ED use.

Neuropsychiatric Disorders as Erratic Attention Regulation – Lessons from Electrophysiology Abstract Attention related electrophysiological waves, such as P300, often deviate from norm in various populations of neuropsychiatric patients. For example, the amplitude is often smaller and the latency is often longer in major depressive disorder, in bipolar disorder and in schizophrenia. On the other hand, in other neuropsychiatric populations, it is often possible to note the opposite phenomena of larger P300 amplitude and shorter latency in comparison with norm, but only for a specific subset of stimuli. This is often reported in various anxiety disorders, substance abuse and various chronic pain syndromes. These findings in the various clinical populations, on their commonalities and differences, are presented in this work. The prevalence of these two types of deviations in the electrophysiological markers of attention, shared by multiple neuropsychiatric populations, raise interesting questions regarding the role of attention deviation and regulation in neuropsychiatry. We present these questions and outline a possible hypothesis in this regard. Furthermore, such potential sensitivity of the attention-related markers to clinical dynamics suggests they could be candidates for monitoring and, potentially, early-sensing of clinical dynamics. Therefore, we discuss the potential usability of such markers.
