The aim of this study was to develop a screening questionnaire that could distinguish individuals at high risk of smartphone overuse from casual users. The reliability, validity, and diagnostic ability of the Smartphone Overuse Screening Questionnaire (SOS-Q) were evaluated. Preliminary items were assessed by 50 addiction experts on-line, and 28 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. The SOS-Q, Young's internet addiction scale, Korean scale for internet addiction, and Smartphone Scale for Smartphone Addiction (S-Scale) were used to assess the concurrent validity...

Insecure attachment is associated with suicidal behavior. This relationship and its possible mediators have not been examined in high-risk psychiatric inpatients with respect to the critical high-risk period following hospital discharge. Attachment styles and perception of entrapment were assessed in 200 high-risk adult psychiatric inpatients hospitalized following suicidal ideation or suicide attempt. Suicidal behaviors were evaluated with the Columbia Suicide Severity Rating Scale at 1-2 months post-discharge...

Marijuana use is associated with psychosis, but its effects are understudied in individuals with preexisting risk for psychotic disorders. This preliminary study examined the acute psychological and physiological effects of smoked marijuana (0.0% or 5.5% Δ(9)-THC) in marijuana users at clinical high-risk (CHR; n = 6) to develop a psychotic disorder, and those not at risk (n = 6), under controlled laboratory conditions. CHR marijuana users exhibited temporary increases in psychotic-like states and decreases in neurocognitive performance during marijuana intoxication but control marijuana smokers did not...

Distinct cognitive deficits have been described in Bipolar disorder (BD), including executive impairments, commonly attributed to frontal dysfunction. However, recent attention has been paid to the heterogeneity of cognitive functioning in this population, suggesting that the executive deficits observed in BD might be due to a loss in fluid intelligence (g). Following our previous line of investigation in multiple neurological and psychiatric conditions we aimed at determining the role of g in frontal deficits in BD...

TNF-related weak inducer of apoptosis (TWEAK) and TNF-related apoptosis-inducing ligand (TRAIL) are members of TNF superfamily, which has various roles in immunologic and inflammatory reactions in the organism. Pathophysiology in bipolar disorder is still under investigation and altered serum levels of cytokines are often encountered. Aim of this study is to detect serum TWEAK and TRAIL levels of patients with bipolar disorder and healthy controls. For this purpose, 55 patients with bipolar disorder -27 manic episode (ME), 28 remission (RE) and 29 healthy controls (HC) were included...

Laura C Wilson, Angela Scarpa
It is well documented in the sexual assault literature that more than half of rape survivors do not label their experience as rape. This is called unacknowledged rape. Although this phenomenon is common and undoubtedly has huge implications for psychotherapy, the impact of acknowledgment status on psychological adjustment is unclear. The present study aimed to delineate the unique impact of rape acknowledgment on psychopathology by examining PTSD symptoms at the cluster level. To examine this, 178 female college students who reported rape completed an online survey, including an assessment of PTSD symptoms in the past month...

The current study aimed to prove the antidepressant-like effects and the probable mechanisms of Schisandrin on depression, which induced by chronic unpredictable mild stress (CUMS) in mice. Four weeks of CUMS exposure resulted in depressive-like behavior, as indicated by the significant decrease in sucrose consumption and increase the immobility time in the forced swim test, but without any influence on the locomotor activity. Further, there were significant downregulations of GDNF/ERK1/2/ROS and PI3K/AKT/NOX signaling pathways in the hippocampus and prefrontal cortex in depressed mice...

The aim of this study was to evaluate the impact of psychoeducation in serum levels of BDNF, NGF and GDNF in young adults presenting bipolar disorder (BD). This is a randomized clinical trial including 39 young adults (18-29 years) diagnosed with BD through the Structured Clinical Interview for DSM-IV (SCID-CV). Participants were randomized in two treatment groups: usual treatment (medication) and combined intervention (medication plus psychoeducation). Depressive symptoms were assessed using the Hamilton Depression Rating Scale (HDRS) and severity of manic and hypomanic symptoms was evaluated through the Young Mania Rating Scale (YMRS)...

The current study explored the relationship between non-suicidal self-injuries (NSSI) and students' perceptions of school among adolescents. A sample of 594 high-school students (54.4% male; mean age 14.96) completed validated self-reported measures. Students were divided into three groups: repetitive-NSSI (more than 6 occasions), occasional-NSSI (at least once but less than 6), and no-NSSI. Multi-nominal regression, controlling for gender, age, and depression symptoms, indicated that teachers' psychological support, a sense of school belongingness, and negative perceptions of peer climate were significantly different between repetitive-NSSI and non-NSSI groups...

REVIEW
Caren J Blacker, Charles P Lewis, Mark A Frye, Marin Veldic
Glutamatergic dysregulation is implicated in the neuropathology of bipolar disorder (BD). There is increasing interest in investigating the role of metabotropic glutamate receptors (mGluRs) in BD and as a target for treatment intervention. Bipolar mGluR studies (published January 1992-April 2016) were identified via PubMed, Embase, Web of Science, and Scopus. Full-text screening, data extraction, and quality appraisal were conducted in duplicate, with strict inclusion and exclusion criteria. The initial literature search for mGluRs in BD, including non-bipolar mood disorders and primary psychotic disorders, identified 1544 articles...

There is evidence supporting an association between the serotonin-transporter-linked polymorphic region (5-HTTLPR) and the Five Factor Model (FFM) of human personality. 5-HTTLPR has also been found to interact with stressful life events to increase risk of psychopathology. In the present study, by taking into account stressful life events in the form of childhood adversity, we examined the association between 5-HTTLPR and FFM traits using an adult Swedish cohort (N = 3112). We found that 5-HTTLPR was significantly associated with openness (to experience)...

Medication non adherence in schizophrenia is a major cause of relapse and hospitalization and remains for clinicians an important challenge. This study investigates the associations between insight, therapeutic alliance, perceived trauma related to psychiatric treatment and medication adherence in patients with schizophrenia. In this multicenter study, 72 patients were assessed regarding symptomatology, self-reported adherence with medication, insight, medication side-effects, therapeutic alliance and perceived trauma related to psychiatric treatment...

Suicidal patients are often excluded from clinical trials of psychiatric medications and from investigations using neurobiological techniques. To evaluate the presence, impact, and stability of active suicidal ideation (SI) across a range of antidepressant trials, we reviewed 14 clinical trials conducted in patients with either major depressive disorder (MDD) or bipolar disorder (BD) (N = 269). Active SI at any time point in the clinical trial was identified and linked to participation in other research procedures...

Emotional memory bias is considered to be an important base of the etiology of depression and can be reversed by antidepressants via enhancing the memory for positive stimuli. Another antidepressant treatment, electroconvulsive therapy (ECT), has rapid antidepressant effect and frequently causes short-term memory impairment. However, it is unclear about the short-term effect of ECT on memory bias. In this study, the incidental memory task with emotional pictures were applied to evaluate the emotional memory of twenty depressed patients at pre- and post-ECT (three days after ECT) compared to twenty healthy controls...

There has been an increased interest in the study of underlying autonomic correlates of emotions. This study tests the hypothesis that high levels of high-frequency heart rate variability (HF HRV) are associated with positive emotions. In addition, we hypothesize that this association will differ according to the type of positive emotion. Also, based on recent findings, we tested the hypothesis that this relationship would be nonlinear. Resting-state HRV was collected and self-report measures of different positive emotions were administered to a sample of 124 volunteers...

The neurotrophic hypothesis of depression is supported by consistent findings of lower serum BDNF levels in depressed patients. Increasing evidence shows different clinical characteristics of patients with psychotic major depression versus nonpsychotic major depression. However, the possible association between BDNF and psychotic symptoms in depression has not been investigated. We recruited 90 treatment-resistant depression (TRD) patients and 90 gender- and age-matched healthy control subjects and examined serum BDNF in both groups...

Lack of inhibitory control is present in impulsive and compulsive personality traits. The Go/No-Go task is one of the most effective means to assess response inhibition measured by the ability to appropriately withhold responding to No-Go stimuli. The aim of this work was to study whether differences in performance of Go/No-Go task predicts differences in personality traits related to inhibitory control. For this purpose 63 healthy participants divided into two groups based on the median split of false alarms on the Go/No-Go task completed Barratt Impulsiveness Scale (BIS-11) and the Maudsley Obsessional Compulsive Questionnaire (MOCI)...

Cognitive control impairments may contribute strongly to the overall cognitive deficits observed in patients diagnosed with schizophrenia. In the current study we explore a specific cognitive control function referred to as conflict adaptation. Previous studies on conflict adaptation in schizophrenia showed equivocal results, and, moreover, were plagued by confounded research designs. Here we assessed for the first time conflict adaptation in schizophrenia with a design that avoided the major confounds of feature integration and stimulus-response contingency learning...

Recent studies have shown that white matter lesions play an important role in the pathogenesis of schizophrenia. DHF-6 is a novel flavanone derivative synthesized in our laboratory. The purpose of the present study was to investigate the effects of DHF-6 on behavioral changes and white matter pathology in a 0.2% cuprizone-fed C57BL/6 mice model. The results showed that cuprizone induced a decrease in spontaneous alternations in the Y-maze test, an increase in locomotor activity in the open field test, demyelination determined by electron microscopy, a decline in the expression of myelin basic protein (MBP), a decrease in the differentiation of oligodendrocyte precursor cells (OPCs) into mature oligodendrocytes (OLs), and an activation of microglia and astrocytes in the corpus callosum measured by western blot and/or immunocytochemical analyses...

Different strategies may be spontaneously adopted to solve most navigation tasks. These strategies are associated with dissociable brain systems. Here, we use brain-imaging and cognitive tasks to test the hypothesis that individuals living with Schizophrenia Spectrum Disorders (SSD) have selective impairment using a hippocampal-dependent spatial navigation strategy. Brain activation and memory performance were examined using functional magnetic resonance imaging (fMRI) during the 4-on-8 virtual maze (4/8VM) task, a human analog of the rodent radial-arm maze that is amenable to both response-based (egocentric or landmark-based) and spatial (allocentric, cognitive mapping) strategies to remember and navigate to target objects...
