Prevalence of Suicidal Behavior and Associated Clinical Correlates in Patients with Behavioral Addictions

The usefulness of an intervention with a serious video game as a complementary approach to cognitive behavioural therapy in eating disorders: A pilot randomized clinical trial for impulsivity management

OBJECTIVE

The aim of the present study was to test the usefulness of an add-on serious video game approach (i.e., Playmancer) to treatment as usual (TAU) on reducing impulsive behaviours and psychopathology in individuals diagnosed with an eating disorder (ED).

METHOD

Thirty-seven patients diagnosed with an ED according to the DSM-5 were included in the present randomized clinical trial (RCT; study record 35,405 in ClinicalTrials.gov) and were randomly assigned to either the TAU or TAU + Playmancer group. All participants completed a clinical interview. Impulsivity (UPPS-P self reported questionnaire and Stroop task) and general psychopathology (SCL-90-R) measures were assessed at: baseline, 4 weeks into treatment, at the end of TAU (after 16 weeks), and follow-up (2 years). In addition, patients in the experimental group underwent a total of nine sessions with Playmancer over the span of 3 weeks.

RESULTS

Patients in both treatment groups (TAU + Playmancer or TAU) improved on Stroop task performance and psychological distress. Additionally, patients in TAU-Playmancer improved on the impulsive trait domain of lack of perseverance. No statistical differences were found regarding treatment outcomes (i.e., treatment adherence and remission of eating symptomatology) when comparing the two treatment groups.

CONCLUSION

Our results suggest that the impulsivity associated with EDs should be addressed and could be modified, as some facets of trait impulsivity improved after Playmancer add-on treatment. Yet, there were no significant differences in treatment outcomes when comparing the two groups and further research needs to be conducted.

Mapping the links between sexual addiction and gambling disorder: A Bayesian network approach

Contemporary literature and recent classification systems have expanded the field of addictions to include problematic behaviours such as gambling and sexual addiction. However, conceptualisation of behavioural addictions is poorly understood and gender-based differences have emerged in relation to how these behaviours are expressed. The current research conducted partial-correlation and Bayesian network analyses to assess the symptomatic structure of gambling disorder and sexual addiction. Convenience community sampling recruited 937 adults aged 18 to 64 years (315 females, Mage = 30.02; 622 males, Mage = 29.46). Symptoms of problematic behaviours were measured using the Online Gambling Disorder Questionnaire (OGDQ) and the Bergen Yale Sex Addiction Scale (BYSAS). Results indicate distinct gender-based differences in the symptom networks of sexual addiction and gambling disorder, with a more complex network observed amongst men for both conditions. Addiction salience, withdrawal and dishonesty/deception were important components of the addictive network. Interpersonal conflict was more central for women while intrapsychic conflict a more prominent issue for men. Differences in the two symptom networks indicate separate disorders as opposed to a single underlying construct. Treating practitioners and community initiatives aimed at addressing sexual addiction and disordered gambling should consider gender, when designing educational or therapeutic interventions.

Suicidal Behaviors and Associated Factors Among Individuals with Gambling Disorders: A Meta-Analysis

The risk for suicidal behaviors including suicide ideations and attempts among individuals with gambling disorder (IWGDs) is high compared to the general population. Little is known about the interplay of mood disorders, alcohol use disorders, and suicidal behaviors among IWGDs. The study aimed to determine the prevalence, sociodemographic characteristics, risky behaviors, mental health disorders, and alcohol use disorders associated with suicide behaviors among IWGDs. Studies published between January 1 1995 and September 1 2022 were obtained from following databases: PubMed, Scopus, Web of Science and Cochrane Library databases. PECOS (population, exposures, comparison, outcome, and study design) criteria were used for selecting studies. The Newcastle-Ottawa Scale (NOS) was used for assessing risk of bias and rated each study in terms of exposure, outcome, and comparability. After initial assessment of 10,243 papers, a total of 39 studies met the eligibility criteria. Among IWGDs, the findings indicated a life-time pooled prevalence rate of 31% for suicide ideations (95% CI, 23-39%), 17% for suicide plans (95% CI, 0-34%), and 16% for suicide attempts (95% CI, 12-20%). Generally, suicide ideations among IWGDs were associated with having any financial debt and having chronic physical illnesses, as well as experiencing depression, mood disorders, and alcohol use disorders. Suicide attempts among IWGDs were associated with being older and having a childhood history of sexual abuse, as well as experiencing depression, mood disorders and alcohol use disorders. Interventions can help to facilitate seeking support among IWGDs by de-stigmatizing mental health disorders as well as improving the quality of care presented to individuals with psychiatric conditions.

Influences of Emotional Information on Response Inhibition in Gaming Disorder: Behavioral and ERP Evidence from Go/Nogo Task

BACKGROUND

Gaming disorder (GD) may impair executive functions such as response inhibition. According to the tripartite neurocognitive model, the interoceptive system generates a state of craving that exacerbates the dysfunction of GD. We speculate that emotional information may play an important role in the mechanism, which leads to impaired response inhibition in people with GD.

METHODS

A three-factor mixed experimental design was adopted in this go/nogo task. The between-subject factor was group (GD or control group), and the within-subject factors were two types of emotional information, task relevance (related or unrelated) and emotional valence (negative or positive).

RESULTS

The GD group had lower nogo accuracies than the control group in the task-unrelated condition and also in the negative condition. Parallelly, the GD group showed faster reactions and lower accuracy in the go trials than the control group under task-unrelated negative conditions. At the neural level, the GD group had smaller amplitudes of nogo-N2 and larger amplitudes of nogo-P3 than the control group in the task-unrelated condition.

CONCLUSIONS

The findings prove the hypothesis of this study that emotional information could be a factor leading to impaired response inhibition in GD individuals. The response inhibition abilities of GD are weakened when processing task-unrelated or negative information, which may be caused by failure of behavioral inhibition and weakened conflict control, resulting in more cognitive resources to complete response suppression under specific conditions. This study provides evidence for weaker response inhibition in GD individuals from the perspective of cognitive-emotional interaction and provides more detailed information for interventions for GD.

Co-Occurring Obsessive-Compulsive Disorder and Compulsive Sexual Behavior: Clinical Features and Psychiatric Comorbidities

Obsessive-compulsive disorder (OCD) commonly co-occurs with other psychiatric conditions. Though research is limited, there is preliminary evidence that OCD also co-occurs with compulsive sexual behavior (CSB). Yet, few studies have investigated the demographic, clinical, and psychiatric comorbidities associated with co-occurring OCD and CSB. To address this gap, the current study aimed to evaluate rates of co-occurring OCD and CSB, identify demographic and clinical factors associated with comorbid OCD and CSB, and assess associated psychiatric comorbidity. Participants (N = 950) were patients of a large multisite treatment for OCD. Standardized self-report measures were used to assess demographic and clinical characteristics such as anxiety, depression, and severity and dimensions of OCD. Semi-structured interviews including the SCID were used to assess psychiatric comorbidities. A total of 36 (3.8%) of participants met the criteria for CSB. Binary logistic regression analysis revealed that males were significantly more likely to present with CSB than females and CSB was associated with greater psychiatric comorbidity, particularly impulse control disorders. These findings suggest that individuals with co-occurring OCD and CSB may have more complex treatment needs, and more tailored interventions may be necessary.

Gambling-related suicides and suicidality: A systematic review of qualitative evidence

The relationship between gambling and suicides or suicidality has received much research attention in recent years. Review studies have already mapped the quantitative occurrence of suicide attempts, suicides, and self-harm among gamblers, and found a positive association. Related comorbidities and conditions have also been charted in previous reviews. However, there is still a gap in knowledge regarding the actual processes that connect gambling and suicidal behavior. To understand these processes, the current paper conducts a systematic review of qualitative evidence on gambling-related suicides and suicidality. The aim was to identify the role of gambling as well as of confounding factors in suicidality, and what kind of support suicidal individuals have received or would need. We searched for relevant literature in seven scientific databases. We included all studies that presented empirical qualitative evidence on gambling-related suicide, suicidality and/or self-harm (N = 20). The results show two main processes that connect gambling and suicidal behavior: indebtedness and shame. At the same time, suicide is a multifactorial phenomenon, and related to other confounding factors. These include psychiatric conditions, personality traits, and life conditions. In many cases, these appear to emerge as a consequence of gambling. Treatment for suicidality has been effective in some cases, but indebtedness and shame may also function as barriers to help-seeking. We conclude that effective prevention is needed by adapting a more comprehensive public health approach and population-level interventions.

Therapeutic management of buying/shopping disorder: A systematic literature review and evidence-based recommendations

The prevalence of buying/shopping disorder (B/SD) has been increasing in the last two decades, and this disorder has a substantial negative impact on general functioning and quality of life. Therefore, a systematic review of the studies dedicated to the efficacy and tolerability of therapeutic interventions, both psychological and pharmacological, might help clinicians to decide on the most evidence-based treatment for these patients. In order to further increase the clinical usefulness of the current review, GRADE-based recommendations were formulated, where enough evidence was found to support such an approach. A number of five electronic databases were searched for single case reports, case series, open-label and double-blind, placebo/active intervention-controlled trials, but other secondary reports (i.e., systematic reviews and meta-analyses) were also included in this analysis. Studies with unspecified designs or those that do not report either qualitatively or quantitively the evolution of B/SD core manifestations were excluded. All data included in the secondary analysis were evaluated using the Joanna Briggs Institute critical appraisal checklists. A total number of 24 manuscripts (i.e., 12 clinical trials, eight case reports, and four reviews) were included. Most of the reviewed studies were of moderate quality, representing a certain limitation of this review and preventing the formulation of high-validity recommendations. Psychotherapy, especially cognitive behavioral therapy (CBT) seems to be the main intervention supported by the current evidence, followed by the combination of antidepressants and CBT, and serotoninergic antidepressants as monotherapy. There is an obvious need to further develop good-quality trials with a more significant number of participants with B/SD and longer follow-up periods.

Shame and guilt activations: Associations and sociodemographic differences among ploysubstance abusers

OBJECTIVES

Shame and guilt in polysubstance abusers are still understudied despite their significance in substance use disorders (SUD). The goal of the current study is to develop a better understanding of how shame and guilt interact among polysubstance abusers who are receiving residential treatment.

METHODS

The sample of two hundred four males with SUD admitted to five rehabilitation centers from two cities in Pakistan participated in this study. For comparison, 215 age-matched healthy individuals were recruited (control). All participants reported their scores on the state shame and guilt scale (SSGS) and demographic form. A cross-sectional study design was adopted.

RESULTS

The group with SUD reported greater activations on SGSS (r = 0.79, p < 0.001) as compared to healthy (control) individuals (r = 0.48, p < 0.001). Further, multivariate analysis indicated that people with SUD who were of older age, unemployed, living in a nuclear family system, with a higher level of education, and low income, experienced higher levels of shame and guilt. Multinomial logistic regression analysis revealed that people with SUD in the age group 41-60 years (OR 5.2, 95%CI 2.4-6.8), unemployed (OR 4.4, 95%CI 3.2-4.7), nuclear family system (OR 5.9, 95%CI 4.5-6.4) and low monthly income group (OR 5.4, 95%CI 3.5-5.8) had a significantly high risk of shame and guilt than the control group.

CONCLUSION

Findings of the current study indicate an association between shame and guilt activation and SUD. These results suggest that polysubstance users may benefit from therapeutic interventions to avoid a generalization of shame and guilt toward their substance use. Reducing shame and guilt should be considered a priority in treating adults with multiple SUD.
