The Prevalence of Impulse Control Disorders and Behavioral Addictions in Eating Disorders: A Systematic Review and Meta-Analysis

Aim: Individuals with eating disorders (EDs) may present with impulse control disorders (ICDs) and behavioral addictions (BAs), which may result in additional suffering and treatment resistance. However, the prevalence of ICDs and BAs in EDs has not been systematically examined. Therefore, this systematic review and meta-analysis aimed to assess the prevalence of ICDs and BAs in ED samples.Methods: A comprehensive electronic database search of the peer-reviewed literature was conducted in the following online databases: MEDLINE, PsycINFO, Embase, and CINAHL from their inception to May 2021. We restricted review eligibility to research studies reporting prevalence for ICDs or BAs in individuals with diagnosed EDs. The outcome for this review was the prevalence of ICDs or BAs in individuals with EDs. A series of random-effects meta-analyses were performed on eligible studies to estimate the pooled proportions and 95% confidence intervals (CIs).Results: Thirty-five studies met the inclusion criteria, including a total of 9,646 individuals identified as having an ED, 18 of these studies specifically examined ICDs/BAs in AN, BN, and BED. Random-effects pooled estimates demonstrated that the comorbid prevalence of any ICD was 22%. The prevalence of comorbid pathological/compulsive buying was highest (19%), followed by kleptomania (18%), pathological internet use (12%), intermittent explosive disorder (4%), trichotillomania (3%), and gambling disorder (2%). In addition, the prevalence of stealing/shoplifting behaviors was 30% in those with EDs.Conclusion: This is the first meta-analysis on the comorbid prevalence of EDs and ICDs/BAs. We found a moderate prevalence for these comorbid conditions, with approximately one out of five individuals with an ED also displaying a comorbid ICD/BA. Although causal inferences cannot be drawn, the numbers strongly suggest that clinical screening/monitoring of ICDs/BAs should be part of the clinical routine in cohorts with EDs. ED settings need either the capacity to manage these disorders or adequate access to relevant services. Further investigations are needed to reveal common underlying pathomechanisms.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/, identifier: CRD42020202044.

STRATEGI REGULASI EMOSI DAN RESILIENSI PADA IBU YANG MENDAMPINGI ANAK STUDY FROM HOME (SFH) DI MASA PANDEMI COVID-19

Penelitian ini bertujuan untuk mengetahui dan menguji secara empiris hubungan antara strategi regulasi emosi terhadap resiliensi pada Ibu yang sedang mendampingi anak Study from Home (SFH) di masa pandemi Covid-19. Hipotesis dari penelitian ini adalah adanya perbedaan tingkat resiliensi Ibu yang mendampingi anak SFH ditinjau dari strategi regulasi emosi yang dimiliki. Alat ukur yang digunakan adalah skala strategi regulasi emosi sejumlah 10 aitem yang mengacu pada teori Gross (2002) dengan dua dimensi, yaitu Suppression dan Cognitive Reappraisal. Kemudian skala yang kedua adalah skala resiliensi sebanyak 47 aitem yang mengacu pada aspek resiliensi dari teori Reivich & Shatte (2002) dengan tujuh dimensi, yaitu : emotion regulation, impulse control, optimism, causal analysis, empathy, self efficacy, dan reaching out. Pemilihan subjek dilakukan dengan cara purposive sampling, yaitu teknik penentuan sampel dengan pertimbangan tertentu yang diterapkan berdasarkan tujuan dari penelitian. Partisipan dalam penelitian ini adalah Ibu yang sedang mendampingi anak belajar dari rumah (Study from Home) di masa pandemi Covid-19, baik itu Ibu yang bekerja maupun yang Ibu yang tidak bekerja atau Ibu Rumah Tangga. Berdasarkan analisis One Way Anova, hasilnya menunjukkan bahwa adanya perbedaan tingkat resiliensi ditinjau dari strategi regulasi emosi yang dimiliki oleh ibu yang mendampingi anak SFH dengan nilai signifikansi sebesar 0,002 (p < 0,05) dengan nilai F hitung 7,349.

Forensic Value of Genetic Variants Associated with Anti-Social Behavior

Insanity defense is sometimes invoked in criminal cases, and its demonstration is usually based on a multifactorial contribution of behavioural, clinical, and neurological elements. Neuroradiological evidence of structural alterations in cerebral areas that involve decision-making and moral reasoning is often accepted as a useful tool in these evaluations. On the other hand, the genetic predisposition to anti-social behavior is still controversial. In this paper, we describe two cases of violent crimes committed by young carriers of genetic variants associated with personality disorder; both the defendants claimed to be insane at the time of the crime. We discuss these cases and review the scientific literature regarding the relationship between legal incapacity/predisposition to criminal behavior and genetic mutations. In conclusion, despite some genetic variants being able to influence several cognitive processes (like moral judgement and impulse control), there is currently no evidence that carriers of these mutations are, per se, incapable of intentionally committing crimes.

Trait Anxiety as a Risk Factor for Impulse Control Disorders in de novo Parkinson’s Disease

Background: In addition to the well-known motor symptoms, patients with Parkinson’s disease (PD) also frequently experience disabling non-motor symptoms including impulse control disorders (ICDs). ICDs are characterized by a loss of voluntary control over impulses, drives, or temptations regarding excessive hedonic behavior. Objective: The present study examined whether depression and anxiety in de novo PD patients predict the prospective development of ICDs. Methods: We selected 330 de novo PD patients from the Parkinson’s Progression Markers Initiative database who were free of ICDs at the start of the study. ICD presence at baseline and follow-up assessments was evaluated via the shortened version of the Questionnaire for Impulsive-Compulsive Disorders (QUIP-S). Baseline depression and anxiety were measured via the Geriatric Depression Scale (GDS-15) and State-Trait-Anxiety Inventory (STAI-Y), respectively. Results: A total of 149 participants (45.2%) developed an ICD at follow-up and average time of ICD onset was 35 months after baseline. Results of a Cox regression analysis showed that STAI-Y scores but not GDS-15 scores significantly predicted ICD presence. Specifically, scores reflecting higher trait anxiety were associated with an increased risk of developing an ICD. This effect was not confounded by age, gender or UPDRS motor score. We also replicated the well-established result that dopamine agonist use is predictive of ICDs. Conclusion: Our findings indicate that higher anxiety levels in de novo PD patients represent a risk factor for ICD development during the course of the disorder. This highlights the need for early and routine based anxiety screening in these patients.

School Entry Plays an Insignificant Role in Attention Performance, Impulse Control, and Motor Activity of Same-Aged Children from Preschool and Elementary School

The transition from preschool to elementary school places demands on children to pay attention, control their impulses, and avoid fidgeting. However, to the best of our knowledge, no studies have investigated whether these characteristics are influenced by elementary school entry. The current study compares same-aged preschool and elementary-school children regarding their attention performance, impulse control, and motor activity. A total of 60 children (30 preschool and 30 elementary school; 6 years old) underwent the Quantified Behavior (Qb) Test. The children’s parents responded to a conventional questionnaire for measuring attention-deficit/hyperactivity disorder. We found that formal schooling (mean: 3 months) did not significantly affect the examined variables ( p > .05). The results imply that improvements in questionnaire and computer test scores shown by previous studies are rather caused by maturation than the educational context. The assumption that inattention ratings increase after school entry because inattention can be better observed in an academic setting could not be verified either. Our study substantiates that the normative data used in clinical practice need not consider the educational context.
