Summary: This study found that problem gamblers experience more and more severe harms compared to problem gamers, with gamblers more likely to suffer financial and work-related harms, while gamers tend to experience physical harms. Gaming disorder seems to be associated with a less severe profile of harm, primarily related to neglect of personal wellbeing and obligations, compared to problem gambling.

Summary: This study evaluated and compared the effects of three cognitive boosting intervention approaches on impulsive action and impulsive choice, finding that cognitive remediation, especially goal management training, may be an effective treatment for addressing impulsive choice in addiction. Preliminary evidence does not support the use of computerised cognitive training or pharmacological enhancers to boost impulse control in addiction.

Summary: This study investigated the impact of impulsive choice, as measured by delay discounting tasks, on treatment outcomes in patients with gambling disorders (GD). The results showed that impulsive choice was associated with GD severity and personality traits, and it also predicted a higher risk of relapses and dropout in different groups of GD patients. The findings highlight the importance of considering impulsive choice in the treatment of GD to improve treatment outcomes.

Summary: The aim of this study was to explore the factors that can influence problematic gambling, specifically focusing on attachment, alexithymia, dissociation, and impulsivity. The sample consisted of 368 regular gamblers who completed an online survey. The results showed that fearful and preoccupied attachment patterns were significantly and positively associated with problematic gambling, and these associations were mediated by alexithymia, dissociation, and impulsivity. These findings provide valuable information for clinical practice and preventive intervention.

Summary: The aim of this study was to compare evidence of a one-factor structure to evidence of a two-factor structure representing two subdomains. Overall, there was stronger support for the two-factor structure. However, the two factors were highly correlated with one another, with most predictors being shared except for one. We recommend continued use of the one-factor structure of the PGSI unless one aims to better understand the relationship between problematic behaviors and adverse consequences.

Summary: Gambling problems are prevalent among homeless individuals, with clinically significant problem gambling and gambling disorder rates ranging from 11.3% to 31.3%. A substantial proportion of homeless individuals also experience subclinical problem gambling. Early detection and treatment models should be implemented to address this issue and provide social support and healthcare services for the homeless.

Summary: This umbrella review and meta-analysis evaluated the methodological rigor of existing meta-analyses on cognitive-behavioral treatment (CBT) for gambling harm. Five meta-analyses met the inclusion criteria, with one rated high rigor, two moderate, and two critically low. By including only moderate- to high-quality meta-analyses, the results showed that CBT significantly reduced gambling disorder severity, frequency, and intensity. This evidence supports clear treatment recommendations for individuals, clinicians, managed care companies, and policymakers.

Summary: This study examined sustained attention problems across a range of psychiatric disorders and found that impaired attention is not specific to ADHD. Several other disorders, such as social phobia, obsessive-compulsive disorder, bulimia nervosa, and intermittent explosive disorder, were associated with significantly larger deficits in sustained attention. Clinicians should screen for a variety of disorders when people report attentional problems, instead of assuming they are due to ADHD.

Summary: This study examined the relationship between religiosity and impulsive and compulsive tendencies among university students. The results showed that higher levels of religiosity were associated with better self-esteem, lower rates of alcohol and drug problems, and lower impulsivity in terms of attention and planning. However, compulsivity did not differ between groups. These findings highlight the importance of understanding the impact of religiosity on mental health.

Summary: Non-suicidal self-injury (NSSI) is more common among women, possibly due to their higher levels of psychological distress. Women also show significant differences in sensation seeking and positive urgency compared to men. Psychological distress partially mediates the relationship between gender and NSSI.

Summary: Compulsivity is relevant to various psychiatric disorders, but it lacks characterization and validated measures at large scale. This study used the Cambridge-Chicago Compulsivity Trait Scale to describe the multidimensional latent structure of self-reported compulsivity in a population-based sample. The results revealed a two-factor model consisting of Perfectionism and Reward Drive dimensions, with discriminant validity and acceptable test-retest reliability. The scale, validated at a large scale, is suitable for studying compulsivity in clinical and nonclinical participants, and normative data are provided for future interpretation.

Summary: Previous research has shown a correlation between the age at which an individual first gambles and problematic behavior later in life, but little is known about how age of gambling onset, particularly as a child or young adult, affects future gambling. This study analyzed data from young adults in the United States and found that an earlier age of gambling onset was associated with betting a higher proportion during a neurocognitive task. There were no significant associations between age of gambling onset and severity of recent pathological gambling, gambling expenditure in the past year, or gambling frequency in the past week.

Summary: This study examines the presence of illegal behaviors in individuals with gambling disorders and their impact. The results show that 43.3% of individuals with gambling disorders reported gambling-related illegal behaviors, which were associated with earlier symptom onset, higher levels of depressive symptoms, worse quality of life, and higher impulsivity. However, these illegal behaviors did not have an impact on treatment response or symptom severity.

Summary: Autistic individuals are more prone to problematic alcohol and substance use compared to the general population. Research shows that around one in three autistic adults may have an alcohol or substance use disorder, while the evidence for behavioral addictions is less clear. Substance use and addictive behaviors may be used by autistic individuals as a way to cope with social anxiety and challenges. However, the lack of literature on the intersection between autism and these conditions hinders progress in health policy, research, and clinical practice.

Summary: The purpose of this study was to validate a gamified battery of neurocognitive tasks for assessing addictive behaviors. The findings showed that the gamified tasks were sufficiently valid for assessing key neurocognitive processes related to addiction. This validation has significant implications for risk detection and the successful deployment of next-generation assessment tools for substance use or misuse and other mental disorders characterized by neurocognitive anomalies.
