Examining academic self-concept as a mediator of the relationship between anxiety and depression: A longitudinal study
Background
Self-concept plays a role as a mediator in the development and maintenance of internalizing symptoms but mechanisms through which the early presence of anxiety symptoms is associated with the subsequent development of depression is unknown. The aim of this longitudinal study was to analyze the mediating role of different areas of self-concept in the relationship between the early development of anxiety symptoms and the later appearance of depressive symptoms.
Methods
A longitudinal study with 3 time-points was conducted, including baseline, 2 months and 12 months from the baseline assessment. A total of 217 children aged 8–12 years participated. Mediation analyses were conducted using PROCESS Macro for SPSS.
Results
Academic self-concept (Time 2) mediated the relationship between Anxiety (Time 1) and Depression (Time 3) when controlling for children's sex and, age, baseline value of the mediator, anxiety (at Times 2 and 3), and depression (at Times 1 and 2). Children with self-reports of higher anxiety symptoms (Time 1) presented lower Academic self-concept (Time 2). Children who reported lower levels of Academic self-concept and Family self-concept (Time 2) were more likely to develop depressive symptoms (Time 3).
Conclusions
Feeling competent in the school environment may be considered a protective factor against the development of depression in childhood. The identification of risk factors facilitates the development and implementation of preventive programs
A protocol to assess cell cycle and apoptosis in human and mouse pluripotent cells
Embryonic stem cells (ESC) and induced pluripotent stem cells (iPSCs) present a great opportunity to treat and model human disease as a cell replacement therapy. There is a growing pressure to understand better the signal transduction pathways regulating pluripotency and self-renewal of these special cells in order to deliver a safe and reliable cell based therapy in the near future. Many signal transduction pathways converge on two major cell functions associated with self-renewal and pluripotency: control of the cell cycle and apoptosis, although a standard method is lacking across the field. Here we present a detailed protocol to assess the cell cycle and apoptosis of ESC and iPSCs as a single reference point offering an easy to use standard approach across the field
Early intervention for obsessive compulsive disorder : An expert consensus statement
© 2019 Elsevier B.V.and ECNP. All rights reserved.Obsessive-compulsive disorder (OCD) is common, emerges early in life and tends to run a chronic, impairing course. Despite the availability of effective treatments, the duration of untreated illness (DUI) is high (up to around 10 years in adults) and is associated with considerable suffering for the individual and their families. This consensus statement represents the views of an international group of expert clinicians, including child and adult psychiatrists, psychologists and neuroscientists, working both in high and low and middle income countries, as well as those with the experience of living with OCD. The statement draws together evidence from epidemiological, clinical, health economic and brain imaging studies documenting the negative impact associated with treatment delay on clinical outcomes, and supporting the importance of early clinical intervention. It draws parallels between OCD and other disorders for which early intervention is recognized as beneficial, such as psychotic disorders and impulsive-compulsive disorders associated with problematic usage of the Internet, for which early intervention may prevent the development of later addictive disorders. It also generates new heuristics for exploring the brain-based mechanisms moderating the ‘toxic’ effect of an extended DUI in OCD. The statement concludes that there is a global unmet need for early intervention services for OC related disorders to reduce the unnecessary suffering and costly disability associated with under-treatment. New clinical staging models for OCD that may be used to facilitate primary, secondary and tertiary prevention within this context are proposed.Peer reviewe

The article presents those selected therapeutic advances judged to be of utmost relevance to the treatment of OCD, based on new and emerging evidence from clinical and translational science. Areas covered include refinement in the methods of clinical assessment, the importance of early intervention based on new staging models and the need to provide sustained well-being involving effective relapse prevention. The relative benefits of psychological, pharmacological and somatic treatments are reviewed and novel treatment strategies for difficult to treat OCD, including neurostimulation, as well as new areas for research such as problematic internet use, novel digital interventions, immunological therapies, pharmacogenetics and novel forms of psychotherapy are discussed.Peer reviewe
Comparative analysis of distinct phenotypes in gambling disorder based on gambling preferences
Background: Studies examining gambling preferences have identified the importance of the type of gambling
practiced on distinct individual profiles. The objectives were to compare clinical, psychopathological and personality
variables between two different groups of individuals with a gambling disorder (strategic and non-strategic
gamblers) and to evaluate the statistical prediction capacity of these preferences with respect to the severity of the
disorder.
Method: A total sample of 2010 treatment-seeking patients with a gambling disorder participated in this
stand-alone study. All were recruited from a single Pathological Gambling Unit in Spain (1709 strategic and 301
non-strategic gamblers). The design of the study was cross-sectional and data were collected at the start of
treatment. Data was analysed using logistic regression for binary outcomes and analysis of variance (ANOVA) for
quantitative responses.
Results: There were significant differences in several socio-demographic and clinical variables, as well as in
personality traits (novelty seeking and cooperativeness). Multiple regression analysis showed harm avoidance and
self-directedness were the main predictors of gambling severity and psychopathology, while age at assessment and
age of onset of gambling behaviour were predictive of gambling severity. Strategic gambling (as opposed to
non-strategic) was significantly associated with clinical outcomes, but the effect size of the relationships was small.
Conclusions: It is possible to identify distinct phenotypes depending on the preference of gambling. While these
phenotypes differ in relation to the severity of the gambling disorder, psychopathology and personality traits, they
can be useful from a clinical and therapeutic perspective in enabling risk factors to be identified and prevention
programs targeting specific individual profiles to be developed
ADHD symptomatology in eating disorders : a secondary psychopathological measure of severity?
Background: Attention-deficit/hyperactivity disorder (ADHD) has commonly been described in psychiatric disorders. Although several studies have found positive associations between abnormal eating patterns during childhood and ADHD, there is a lack of studies on ADHD and Eating Disorders (ED). The aims of this exploratory study were 1) to assess the ADHD symptoms level in ED and to ascertain whether there are differences among ED subtypes; 2) to analyze whether the presence of ADHD symptoms is associated with more severe eating disorder symptoms and greater general psychopathology; and 3) to assess whether the ADHD symptoms level is associated with specific temperament and character traits. Methods: 191 female ED patients were included. Assessment was carried out with the EDI-2, ASRS-v1.1, the SCL-90-R and the TCI-R. Results: The ADHD symptoms level was similar in bulimia, eating disorder not otherwise specified and binge eating subtypes, and lower in anorexic patients. Obsessiveness and Hostility were significantly positively associated with ADHD symptoms. A path model showed that ADHD was associated with high Novelty Seeking and low Self-Directedness, whereas ED severity was influenced by ADHD severity and low Self-Directedness. Conclusions: Bingeing/purging ED subtypes have a high ADHD symptoms level, also related with more severe eating, general and personality psychopathology
Cognitive behaviour therapy response and dropout rate across purging and nonpurging bulimia nervosa and binge eating disorder : DSM-5 implications
Background: With the imminent publication of the new edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), there has been a growing interest in the study of the boundaries across the three bulimic spectrum syndromes [bulimia nervosa-purging type (BN-P), bulimia nervosa-non purging type (BN-NP) and binge eating disorder (BED)]. Therefore, the aims of this study were to determine differences in treatment response and dropout rates following Cognitive Behavioural Therapy (CBT) across the three bulimic-spectrum syndromes. Method: The sample comprised of 454 females (87 BED, 327 BN-P and 40 BN-NP) diagnosed according to DSM-IV-TR criteria who were treated with 22 weekly outpatient sessions of group CBT therapy. Patients were assessed before and after treatment using a food and binging/purging diary and some clinical questionnaires in the field of ED. "Full remission" was defined as total absence of binging and purging (laxatives and/or vomiting) behaviors and psychological improvement for at least 4 (consecutive). Results: Full remission rate was found to be significantly higher in BED (69.5%) than in both BN-P (p < 0.005) and BN-NP (p < 0.001), which presented no significant differences between them (30.9% and 35.5%). The rate of dropout from group CBT was also higher in BED (33.7%) than in BN-P (p < 0.001) and BN-NP (p < 0.05), which were similar (15.4% and 12.8%, respectively). Conclusions: Results suggest that purging and non-purging BN have similar treatment response and dropping out rates, whereas BED appears as a separate diagnosis with better outcome for those who complete treatment. The results support the proposed new DSM-5 classification
Manifesto for a European research network into Problematic Usage of the Internet
The Internet is now all-pervasive across much of the globe. While it has positive uses (e.g. prompt access to information, rapid news dissemination), many individuals develop Problematic Use of the Internet (PUI), an umbrella term incorporating a range of repetitive impairing behaviours. The Internet can act as a conduit for, and may contribute to, functionally impairing behaviours including excessive and compulsive video gaming, compulsive sexual behaviour, buying, gambling, streaming or social networks use. There is growing public and National health authority concern about the health and societal costs of PUI across the lifespan. Gaming Disorder is being considered for inclusion as a mental disorder in diagnostic classification systems, and was listed in the ICD-11 version released for consideration by Member States ( http://www.who.int/classifications/icd/revision/timeline/en/ ). More research is needed into disorder definitions, validation of clinical tools, prevalence, clinical parameters, brain-based biology, socio-health-economic impact, and empirically validated intervention and policy ap- proaches. Potential cultural differences in the magnitudes and natures of types and patterns of PUI need to be better understood, to inform optimal health policy and service development. To this end, the EU under Horizon 2020 has launched a new four-year European Cooperation in Science and Technology (COST) Action Programme (CA 16207), bringing together scientists and clinicians from across the fields of impulsive, compulsive, and addictive disorders, to advance networked interdisciplinary research into PUI across Europe and beyond, ultimately seeking to inform regulatory policies and clinical practice. This paper describes nine critical and achievable research priorities identified by the Network, needed in order to advance understanding
of PUI, with a view towards identifying vulnerable individuals for early intervention. The network
shall enable collaborative research networks, shared multinational databases, multicentre
studies and joint publications
