Background: Guidance on how different disciplines from the natural, behavioural and social sciences can collaborate to resolve complex public health problems is lacking. This article presents a checklist to support researchers and principle investigators to develop and implement interdisciplinary collaborations. Methods: Fourteen individuals, representing 10 disciplines, participated in in-depth interviews to explore the strengths and challenges of working together on an interdisciplinary project to identify the determinants of substance use and gambling disorders, and to make recommendations for future interdisciplinary teams...

The aim of this study was to identify predictors of treatment dropout in a sample of gamblers attending a specialist clinic for gambling disorder. We analysed data on 846 treatment-seeking pathological gamblers. Firstly, we investigated differences in socio-demographic and clinical variables between treatment completers and pre-treatment dropouts, as well as between treatment completers and during-treatment dropouts. Subsequently, variables were entered into a multinomial logistic regression model to identify significant predictors of pre-treatment and in-treatment dropout...

Attention-deficit/hyperactivity disorder (ADHD) is a common condition with comorbid insomnia reported in >70% of children and adults. These patients demonstrate delays in sleep-wake rhythms, nocturnal rise in melatonin, and early morning rise in cortisol. Given that standard psychopharmacologic treatments for ADHD often do not completely control symptoms in participants with circadian rhythm delay, we sought to test whether bright light therapy (BLT) advances circadian rhythms and further reduces ADHD symptoms over standard treatments...

Gambling has been associated with increased sympathetic nervous system output and stimulation of the hypothalamic-pituitary-adrenal axis. However it is unclear how these systems are affected in pathological gambling. This study aimed to investigate the effect of the Trier Social Stress Test (TSST) on cortisol and on cardiac interbeat intervals in relation to impulsivity, in a sample of male pathological gamblers compared to healthy controls. In addition, we investigated the correlation between the TSST, duration of the disorder and impulsivity...

BACKGROUND: Impulse control disorders/other compulsive behaviours ('ICD behaviours') occur in Parkinson's disease (PD), but prospective studies are scarce, and prevalence and clinical characteristics of patients are insufficiently defined. OBJECTIVES: To assess the presence of ICD behaviours over a 2-year period, and evaluate patients' clinical characteristics. METHODS: A prospective, non-interventional, multicentre study (ICARUS (Impulse Control disorders And the association of neuRopsychiatric symptoms, cognition and qUality of life in ParkinSon disease); SP0990) in treated Italian PD outpatients...

HIV-infected individuals (HIV+) has 2-3 times the rate of tobacco smoking than the general population, and whether smoking may lead to greater psychiatric symptoms or cognitive deficits remains unclear. We evaluated the independent and combined effects of being HIV+ and chronic tobacco-smoking on impulsivity, psychopathological symptoms and cognition. 104 participants [27 seronegative (SN)-non-Smokers, 26 SN-Smokers, 29 HIV+ non-Smokers, 22 HIV+ Smokers] were assessed for psychopathology symptoms (Symptom Checklist-90, SCL-90), depressive symptoms (Center for Epidemiologic Studies-Depression Scale, CES-D), impulsivity (Barratt Impulsiveness Scale, BIS), decision-making (The Iowa Gambling Task, IGT, and Wisconsin Card Sorting Test, WCST), and cognition (seven neurocognitive domains)...

This study aimed to examine associations between gambling level and clinically relevant measures, including psychiatric disorders and suicidality, in a nationally representative sample of U.S. veterans. Data on 3157 U.S. veterans were analyzed from the National Health and Resilience in Veterans Study. Chi square tests and analyses of variance were used to assess associations between gambling level, and demographic, military, and personality characteristics. Multinomial logistic regressions using stepwise selection were used to identify independent correlates of recreational gambling and at-risk/problem gambling (ARPG)...

BACKGROUND: Impulsivity is understood to be a multidimensional construct involving aspects such as impulsive choice and impulsive traits. Delay discounting, the tendency to place greater value in immediate rewards over larger, long-term rewards, has been associated with maladaptive choices in gambling disorder (GD). Delay discounting is known to evolve with age; though no study to date has evaluated the interactions between impulsivity, GD severity and age in treatment-seeking patients...

Virtual reality (VR) can be used in the treatment of gambling disorder to provide emotionally charged contexts (e.g., induce cravings) where patients can practice cognitive behavior therapy (CBT) techniques in the safety of the therapist's office. This raises practical questions, such as whether the cravings are sufficient to be clinically useful but also manageable enough to remain clinically safe. Pilot data are also needed to test the development of a treatment manual and prepare large randomized control trials...

The clinical diagnosis and symptoms of major depressive disorder (MDD) have been closely associated with impairments in reward processing. In particular, various studies have shown blunted neural and behavioral responses to the experience of reward in depression. However, little is known about whether depression affects individuals' valuation of potential rewards during decision-making, independent from reward experience. To address this question, we used a gambling task and a model-based analytic approach to measure two types of individual sensitivity to reward values in participants with MDD: 'risk preference,' indicating how objective values are subjectively perceived, and 'inverse temperature,' determining the degree to which subjective value differences between options influence participants' choices...

The modern gambling industry has, by-in-large, assumed a duty of care to minimize the risks associated with gambling, which has manifested in responsible gambling (RG) programming (e.g., educating players about the odds of success). The current study fills a void in gambling operators, regulators, and researchers ability to measure RG beliefs and behavior in their player-base, with the development and validation of the Positive Play Scale (PPS). In Study 1, we reviewed the literature and consulted 30 players as well as 10 RG experts to help generate a definition of RG beliefs and behavior that helped guide item generation...

BACKGROUND: Histone lysine demethylases (KDMs) are of interest as drug targets due to their regulatory roles in chromatin organization and their tight associations with diseases including cancer and mental disorders. The first KDM inhibitors for KDM1 have entered clinical trials, and efforts are ongoing to develop potent, selective and cell-active 'probe' molecules for this target class. Robust cellular assays to assess the specific engagement of KDM inhibitors in cells as well as their cellular selectivity are a prerequisite for the development of high-quality inhibitors...

REVIEW
Shae-Leigh Vella, Nagesh Pai
Recently interest in the phenomenon of food addiction has increased substantially since the inclusion of gambling disorder in the DSM-5. However the phenomenon of food addiction remains controversial and the designation continues to lack clear consideration. Few researchers have offered an explicit theoretical definition of the phenomenon which is fundamental; as it not only pertains to the aetiology it also directs research and management of the phenomenon. Therefore this review explores 'what is in a name'? Specifically possible aetiologies of food addiction, eating addiction and food addiction as an eating disorder are reviewed and the potential DSM-5 classification espoused...

INTRODUCTION: Gambling disorder (GD) is a prevalent psychiatric condition whose severity is typically defined by the number of DSM-5 criteria met out of a maximum of nine. The relationships between the levels of gambling severity, thus defined, and other measures of psychopathology and everyday functioning are clinically important. METHODS: Baseline data were collected in patients with GD, conducted from 2001 to 2016. Participants completed clinical interviews and questionnaires...

Adverse childhood experiences (ACEs), such as sexual and physical abuse, have been established as risk factors for the development of disordered gambling. The underlying mechanism by which ACEs influence disordered gambling, however, remains unknown. The aims of the present research were to comprehensively investigate ten types of childhood adversity and their relationships to disordered gambling in adulthood, and to test whether emotion dysregulation mediated the relationship between ACEs and disordered gambling...

Motor impulsivity, which is an impairment in withholding and cancelling inappropriate responses, may account for the inability for pathological gamblers (PGs) to inhibit their urges to gamble. The aim of this systematic review was to perform a quantitative and qualitative synthesis of existing studies in order to assess whether PGs without comorbid substance use disorder have elevated motor impulsivity, relative to healthy controls. An exhaustive literature search led to the identification of 20 studies which met inclusion criteria...

Most treatment for gambling disorder is provided on an outpatient basis. Only a small number of jurisdictions in North America provide higher levels of gambling treatment, such as residential or intensive outpatient (IOP) care, despite the potential need for these services. Further, there appear to be few guidelines for determining appropriate level of gambling treatment. The aim of the present study was to assess the appropriateness of higher levels of problem gambling care among clients receiving outpatient treatment...

Borderline Personality Disorder (BPD) is a disabling and difficult-to-treat mental disease. One of its core features is a significant difficulty in affect regulation, which is often accompanied by Non-Suicidal Self-Injury (NSSI). It is suggested that this type of behavior elicits positive emotions and mitigates emotional distress, and therefore can ultimately be reinforced and promoted. In spite of the high prevalence of NSSI behaviors (also in non-BPD samples), their role in modulating reward-related processes has not yet been investigated in BPD patients...

BACKGROUND AND OBJECTIVES: Exposure to traumatic events is common among patients with substance use disorders (SUD). In patients with non-substance-related disorders, especially with gambling disorders (GD) and internet addiction (IA), traumatic childhood experiences have not been investigated extensively. The objective of this study was to compare trauma histories in patients with GD and IA to patients with heroin dependence. METHODS: Cross-sectional surveys including the childhood trauma questionnaire (CTQ) and clinical data among 107 participants; 59 patients with non-substance-related disorders (GD [n = 39]; IA [n = 20]) were compared to 28 patients prescribed injectable heroin for opioid dependence in heroin-assisted treatment (HAT) and to a healthy control group (HC) (n = 20)...
