A daily diary investigation of self-regulation in gambling

OBJECTIVE

Limit-setting strategies have the potential to assist in reducing problem gambling, but there is little research on self-imposed gambling limits and factors that restrain self-regulation once gambling has been initiated. Using daily diary approach, we investigated individual difference and proximal factors associated with gambling limit violations.

METHOD

Participants were 103 individuals who gambled regularly and had set a goal to limit their gambling. Participants completed a baseline measure of trait self-control and questions about gambling and limit violations over 21 days. We examined factors associated with setting and maintaining limits across episodes of gambling as well as within-person factors associated with limit violations, including the moderating role of trait self-control.

RESULTS

We found that episodes of gambling where limits were set and violated were associated with riskier gambling and more negative emotional responses. In addition, gambling limits were more likely to be violated on days when temptations to violate limits were high and by people with low trait self-control, whereas urges to gamble were associated with a reduced likelihood of limit violations. Trait self-control moderated the relationship between daily stress/tension and limit violations. Low stress/tension was associated with greater limit violations for those with lower trait self-control, but the likelihood of violating limits increased on high stress days for those with higher trait self-control.

CONCLUSIONS

Individuals may benefit from greater awareness of temptations to violate gambling limits and the impact of daily stressors, particularly for those with high trait self-control who are most successful when stress/tension is low. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Estradiol Replacement as a Potential Enhancer of Working Memory and Neuroplasticity in Hypogonadal Trans Women

INTRODUCTION

The cognitive effects of cross-sex hormone therapy (CSHT) are not well understood. In cisgender individuals, sex hormone therapy can impact neurotransmitter levels and structural anatomy. Similarly, in gender-diverse persons, CSHT has been associated with neural adaptations, such as growth in brain structures resembling those observed in cisgender individuals of the same sex. Hormone-related changes in learning and memory, as seen in menopause, are associated with physiological hypogonadism or a decline in hormones, such as estradiol. The present study examined the effect of estradiol administration in humans on glutamate concentration in brain regions involved in semantic and working memory (i.e., the dorsolateral prefrontal cortex (DLPFC), the posterior hippocampus, and the pregenual anterior cingulate cortex (ACC)) and its relationship with memory.

METHODS

Eighteen trans women (male biological sex assigned at birth) ceased CSHT for 30-days for a washout phase (t1) upon study enrollment to reach a hypogonadal state. Working and semantic memory, cognition, hormonal assays, and brain imaging were assessed. Participants resumed CSHT for 60-days for a replacement phase (t2), after which the same evaluations from t1 were repeated.

RESULTS

Estradiol increased among trans women after 60-days of resumed CSHT with significant improvements in semantic memory compared to the hypogonadal phase. Working memory recall was significantly and positively correlated to glutamate in the DLPFC during the reinstatement phase, although the relationship was not moderated by levels of estradiol.

DISCUSSION

These results may have clinical implications for the therapeutic effects of estradiol replacement serving as a protective factor against cognitive decline and impairment for trans women post-gonadectomy.

Increased gray matter following mindfulness-based stress reduction in breast cancer survivors with chronic neuropathic pain: preliminary evidence using voxel-based morphometry

PURPOSE

To investigate the impact of Mindfulness-Based Stress Reduction (MBSR) on gray matter volume (GMV) in female breast cancer survivors who suffer from chronic neuropathic pain (CNP).

METHODS

Voxel-based morphometry (VBM) was used to explore differences in GMV in 13 MBSR trainees and 10 waitlisted controls, with MRI scans and self-report measures completed pre- and post-8 weeks of training.

RESULTS

Compared to controls, the MBSR group had greater GMV in the angular gyrus and middle frontal gyrus post-training. The MBSR group's right parahippocampal gyrus GMV increased from pre- to post-training, whereas the control group's left parahippocampal gyrus, precuneus, middle temporal gyrus, and right cuneus GMV decreased over the same time period. Pain interference was significantly reduced and mindfulness was significantly increased following MBSR for the intervention group only.

CONCLUSIONS

MBSR was associated with increased GMV in regions where GMV is known to (1) increase with mindfulness and reorientation of attention and (2) decrease with the experience of chronic neuropathic pain. By contrast, the control group's decreases in GMV may be due to the negative effects of CNP which potentially may be reduced with MBSR, though further research is needed.

IMPLICATIONS FOR CANCER SURVIVORS

Given the poor efficiency of pharmacotherapies in a high percentage of women with neuropathic pain following breast cancer treatment, adjunct methods are required. MBSR may affect the brain to help alter attention and perception of pain, thus playing a potentially important role in the path to wellness for breast cancer survivors.

A meta-analysis of emotional regulation outcomes in psychological interventions for youth with depression and anxiety

Difficulties in applying emotional regulation (ER) skills are associated with depression and anxiety symptoms, and are common targets of treatment. This meta-analysis examined whether improvements in ER skills were associated with psychological treatment outcomes for depression and/or anxiety in youth. A multivariate, random-effects meta-analysis was run using metafor in R. Inclusion criteria included studies that were randomized controlled trials (RCTs) of a psychological intervention for depression and/or anxiety in patients aged 14-24, were peer reviewed, were written in English, measured depression and/or anxiety symptoms as an outcome and measured ER as an outcome. Medline, Embase, APA PsycInfo, CINAHL and The Cochrane Library were searched up to 26 June 2020. Risk of bias (ROB) was assessed using the Cochrane Collaboration Risk of Bias 2.0 tool. The meta-analysis includes 385 effect sizes from 90 RCTs with total N = 11,652. Psychological treatments significantly reduced depression, anxiety, emotion dysregulation (k = 13, Hedges' g = 0.54, P < 0.001, 95% confidence interval (CI) = 0.30-0.78) and disengagement ER (k = 83, g = 0.24, 95% CI = 0.15-0.32, P < 0.001); engagement ER also increased (k = 82, g = 0.26, 95% CI = 0.15-0.32, P < 0.001). Improvements in depression and anxiety were positively associated with improved engagement ER skills, reduced emotion dysregulation and reduced disengagement ER skills. Sensitivity considered study selection and publication bias. Longer treatments, group formats and cognitive-behavioural orientations produced larger positive associations between improved ER skills and reduced symptoms. ER skill improvement is linked to depression and anxiety across a broad range of interventions for youth. Limitations of the current study include reliance on self-report measures, content overlap between variables and inability to test the directionality of associations.

A Multi-Method Investigation of Normative and Pathological Personality Across the Spectrum of Gambling Involvement

Pathological Gambling (PG) has been linked to both specific personality traits and personality disorders (PDs). However, previous studies have used a wide variety of research designs that preclude clear conclusions about the personality features that distinguish adults with PG from other groups. The current investigation seeks to advance this research by using a sample including adults who do not gamble, who gamble socially, and who exhibit PG, using self-report, informant-report, and interview-rated measures of personality traits and disorders. A total of 245 adults completed measures of gambling behaviour and problems, as well as normative and pathological personality over two assessment visits. A multivariate ANCOVA was conducted to investigate differences between groups. Analyses supported numerous group differences including differences between all groups on the Neuroticism facet of Impulsivity, and between non-gambling/socially gambling and PG groups on the Conscientiousness facet of Self-Discipline. Adults with PG exhibited more symptoms of Borderline, Paranoid, Schizotypal, Avoidant, and Dependent PDs than adults who gamble socially or not at all. The current investigation provides a comprehensive survey of personality across a wide range of gambling involvement, using a multi-method approach. Our findings help to clarify the most pertinent personality risk factors for PG.
