Rates of Intimate Partner Violence Perpetration and Victimization Among Adults With ADHD

Adult ADHD Symptoms in a Large Metropolitan Area From Brazil: Prevalence and Associations with Psychiatric Comorbidity, Bullying, Sexual Abuse, and Quality of Life

OBJECTIVE

The aim of this study was to investigate the prevalence and psychiatric correlates of symptomatic ADHD in a large metropolitan area of a middle-income country.

METHODS

An in-person household survey with randomly selected 2,297 adults aged 19 to 60 from Rio de Janeiro, Brazil, assessed by trained lay interviewers. The Adult Self-Rating Scale Screener (ASRS-6) was used. Chi-square and logistic regression were conducted.

RESULTS

ADHD prevalence was 4.59 (95% CI [3.56, 5.44]). Those with ADHD were younger and more often unemployed; they displayed more psychiatric symptoms (depression, anxiety, and alcohol abuse) and a history of bullying and sexual abuse. They also had worse physical health indicators. Findings remained significant when controlling for socioeconomic variables.

CONCLUSION

Adults with symptomatic ADHD from a large metropolitan area in Brazil show a pattern of findings consistent with what has been observed in higher-income countries.

Attention-deficit/hyperactivity disorder as a risk factor for being involved in intimate partner violence and sexual violence: a systematic review and meta-analysis

BACKGROUND

Intimate partner violence (IPV) and sexual violence (SV) are significant problems world-wide, and they affect women disproportionally. Whether individuals with attention-deficit/hyperactivity disorder (ADHD) are at an increased risk of being involved in these types of violence is unclear.

METHODS

We carried out a systematic review and meta-analysis (PROSPERO registration CRD42022348165) of the associations between ADHD and being the victim or perpetrator of IPV and SV. Ratios of occurrence of violence were pooled in random-effects models and study risk of bias was evaluated using the Newcastle-Ottawa Scale.

RESULTS

A search on multiple databases, carried out on 7 October 2022, yielded 14 eligible studies (1 111 557 individuals). Analyses showed a higher risk of ADHD individuals being involved in IPV as perpetrators (six studies, OR 2.5, 95% CI 1.51-4.15) or victims (four studies, OR 1.78, 95% CI 1.06-3.0). Likewise, individuals with ADHD were at increased risk of being perpetrators (three studies, OR 2.73, 95% CI 1.35-5.51) or victims of SV (six studies, OR 1.84, 95% CI 1.51-2.24). Results were overall robust to different analytical choices.

CONCLUSIONS

Individuals with ADHD are at an increased risk of being involved in cases of violence, namely IPV and SV, either as victims or perpetrators. Although the causal path or mediating variables for these results are still unclear, this increased risk should inform evidence-based psychoeducation with individuals with ADHD, their families, and partners about romantic relationships and sexuality.

Predictors of Sexual Victimization Among Autistic and Non-Autistic College Students

PURPOSE

This study examined predictors of sexual victimization among autistic and non-autistic college students. Specifically, we aimed to determine whether autistic students are more likely than non-autistic students to experience unwanted sexual contact and sexual assault, controlling for co-occurring diagnoses. We also aimed to determine whether students with other disabilities, specifically ADHD, learning disability (LD), and psychological disorders, are more likely than students without these disabilities to experience unwanted sexual contact and sexual assault.

METHODS

Autistic students (n=270) and non-autistic students (n=270) who had participated in a nationwide survey were matched on demographic characteristics and co-occurring diagnoses. Logistic regression analyses were conducted to address the research questions and evaluate predictors of unwanted sexual contact and sexual assault.

RESULTS

Autistic students were as likely as non-autistic students to have experienced unwanted sexual contact and sexual assault, controlling for co-occurring diagnoses. Regardless of autism diagnostic status, students with ADHD were more likely than students without ADHD to have experienced unwanted sexual contact and sexual assault.

CONCLUSIONS

Although autism diagnostic status was not a significant predictor of unwanted sexual contact or sexual assault, other factors associated with increased risk of sexual victimization, such as co-occurring ADHD, are likely to be found in autistic populations. This study highlights the importance of educational, social, and institutional supports to decrease sexual victimization among college students with neurodevelopmental disabilities.

"For Me, 'Normality' is Not Normal": Rethinking Medical and Cultural Ideals of Midlife ADHD Diagnosis

According to psychiatry, Attention-Deficit/Hyperactivity Disorder (ADHD) is a chronic condition beginning in early life. Psychiatry advocates for early diagnosis to prevent comorbidities that may emerge in untreated cases. "Late"-diagnosis is associated with various hazards that might harm patients' lives and society. Drawing on fieldwork in Israel, we found that 'midlife-ADHDers,' as our informants refer to themselves, express diverse experiences including some advantages of being diagnosed as adults rather than as children. They share what it means to experience "otherness" without an ADHD diagnosis and articulate how being diagnosed "late" detached them from medical and social expectations and allowed some to nurture a unique ill-subjectivity, develop personal knowledge, and invent therapeutic interventions. The timeframe that psychiatry conceives as harmful has been, for some, a springboard to find their own way. This case allows us to rethink 'experiential time'-the meanings of timing and time when psychiatric discourse and subjective narratives intertwine.

Functional Impairments Associated With ADHD in Adulthood and the Impact of Pharmacological Treatment

OBJECTIVE

Among untreated adults, functional impairments associated with ADHD are widespread and cumulative, and can include social, educational, and professional impairments, increased risk of accidents and mortality, and reduced quality of life. Here, we review the most prominent functional impairments in adults with ADHD and summarize evidence describing the potential role of medication in improving outcomes.

METHOD

Articles related to the search terms "ADHD," "adult," and functional impairments were identified through Google Scholar and PubMed and selected for inclusion based on four criteria: strength of evidence, relevance to current challenges in adult ADHD, impact on the field, and recency of the results.

RESULTS

We identified 179 papers to support the conclusions on the relationship between ADHD and functional impairments, and the impact of pharmacological therapy on functional impairments.

CONCLUSION

This narrative review provides evidence that pharmacological treatment can be effective in minimizing not only the symptoms of ADHD, but its functional consequences as well.

Neurodevelopmental disorders and subsequent risk of violent victimization: exploring sex differences and mechanisms

BACKGROUND

Neurodevelopmental disorders (NDs) are associated with experiences of victimization, but mechanisms remain unclear. We explored sex differences and the role of familial factors and externalizing problems in the association between several NDs and violent victimization in adolescence and young adulthood.

METHODS

Individuals born in Sweden 1985-1997, residing in Sweden at their 15th birthday, were followed until date of violent victimization causing a hospital visit or death, death due to other causes, emigration, or December 31, 2013, whichever came first. The exposures were diagnoses of attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), intellectual disability (ID) and other NDs. We used three different Cox regression models: a crude model, a model adjusted for familial confounding using sibling-comparisons, and a model additionally adjusted for externalizing problems.

RESULTS

Among 1 344 944 individuals followed, on average, for 5 years, 74 487 were diagnosed with NDs and 37 765 had a hospital visit or died due to violence. ADHD was associated with an increased risk of violent victimization in males [hazard ratio (HR) 2.56; 95% confidence interval (CI) 2.43-2.70) and females (HR 5.39; 95% CI 4.97-5.85). ASD and ID were associated with an increased risk of violent victimization in females only. After adjusting for familial factors and externalizing problems, only ADHD was associated with violent victimization among males (HR 1.27; 95% CI 1.06-1.51) and females (HR 1.69; 95% CI 1.21-2.36).

CONCLUSIONS

Females with NDs and males with ADHD are at greater risk of being victim of severe violence during adolescence and young adulthood. Relevant mechanisms include shared familial liability and externalizing problems. ADHD may be independently associated with violent victimization.

Online Crowdsourcing as a Quasi-Experimental Method for Collecting Data on the Perpetration of Alcohol-Related Partner Aggression

Cross-sectional survey, prospective, and experimental data have been evaluated to better understand the role of alcohol as a contributing cause of intimate partner aggression. Laboratory-based alcohol administration studies provide controlled data regarding causality, but the use of this methodology lacks ecological validity and has been hampered by rigorous procedural and financial demands. Online crowdsourcing is an emerging pseudoexperimental methodology with low costs, rapid data collection, access to diverse populations, greater ecological validity, and the potential to facilitate prolific research to supplement the chronic scarcity of experimental data. The current rapid review first summarizes prior methodological approaches to investigating the proximal influence of alcohol on partner aggression, then reviews prior crowdsourcing research in the disparate areas of alcohol and partner aggression, then describes aggression paradigms that may be readily adapted to online administration. We conclude by introducing recommendations for future quasi-experimental research investigating alcohol-related partner aggression research using the online crowdsourcing methodology. Initial evidence suggests that online crowdsourcing may yield appropriate samples and that existing paradigms may be adapted to rapidly, efficiently, and ethically supplement experimental alcohol-related partner aggression research.

Birds of a Feather: An Examination of ADHD Symptoms and Associated Concerns in Partners of Adults with ADHD

OBJECTIVE

Adults often select romantic partners who behave like they do (i.e. assortative mating). However, little is known about whether assortative mating is common among adults with attention-deficit/hyperactivity disorder (ADHD) and whether it is related to associated problems.

METHOD

About 94 adults without ADHD, 43 adults with childhood ADHD histories but without current symptoms or impairment (ADHD-Desist), 27 adults with childhood ADHD histories and elevated current symptoms and impairment (ADHD-Persist) rated their partners' ADHD symptoms and their own associated problems (e.g., intimate partner violence, financial difficulties).

RESULTS

The ADHD-Persist group reported that their partners exhibited more ADHD symptoms than the ADHD-Desist group and those without ADHD. Adults in the ADHD-Persist group who had partners with elevated ADHD symptoms endorsed high intimate partner violence and financial difficulties.

CONCLUSION

Assortative mating appears to be common among adults with ADHD, especially those with persistent symptoms, and to increase risk of additional problems.

Examining Link Between Childhood ADHD and Sexual Assault Victimization

Objective: Adults with ADHD are often victims of psychological and physical violence by romantic partners, but less is known regarding whether ADHD is associated with sexual assault victimization. Method: Adults with (n = 97) and without childhood histories of ADHD (n = 121) rated their experiences with sexual assault victimization and additional risk factors (i.e., alcohol abuse, illicit drug use, and experiencing child abuse). Results: Adults with ADHD histories were more likely to report being victims of sexual assault, especially attempted rape or rape, than adults without ADHD histories. The rate of rape victimization was not greater for adults with ADHD histories and persistent symptoms or additional risk factors. Conclusion: Research is needed to investigate potential mechanisms explaining the link between ADHD and sexual victimization. Clinicians seeking to prevent at-risk populations from becoming victims, or to provide services for victims, should consider screening adults for ADHD histories.

Adult ADHD and romantic relationships: What we know and what we can do to help

It has been widely maintained that enduring and healthy romantic relationships are critical to quality of life in adulthood, and can buffer the impact of adversity, including psychological disorder. Unfortunately, much research points toward adults with attention-deficit hyperactivity disorder (ADHD) having short-lived and discordant romantic relationships. Despite this ample evidence, relatively little research has focused on identifying specific factors that may strengthen or explain their relational difficulties, which would have obvious relationship distress prevention and intervention implications. The current study reviews the state of the literature on romantic relationships in adults with ADHD, including differences that have been established between ADHD and non-ADHD populations as well as distal and proximal factors that appear to increase risk of relationship distress of adults with ADHD. Finally, notable gaps in the literature are identified and implications are raised with regards to prevention and intervention efforts designed to address functional impairment in adults with ADHD.

The association between reinforcement sensitivity and substance use is mediated by individual differences in dispositional affectivity in adolescents

BACKGROUND

Adolescence marks the onset of substance use experimentation and adolescents are particularly vulnerable to certain negative effects of substances. Some evidence indicates reinforcement sensitivity is associated with substance use, though little is known about mechanisms underlying such association.

AIMS

in the current study were to examine, (1) associations between behavioral activation (BAS) and behavioral inhibition (BIS) system sensitivity, positive (PA) and negative affectivity (NA), and alcohol use and alcohol problems as well as tobacco, and marijuana use, and whether (2) associations are mediated by PA or NA.

METHODS

Participants were a community sample of N = 125 adolescents (M_age = 15.67 years; SD = 0.93; 52% boys) who completed self-report measures.

RESULTS

evinced associations, generally as expected, across variables (all ps < 0.05). In mediation analyses, an association emerged between BIS sensitivity and alcohol use, mediated by NA (95%CIs [0.034; 0.390]); greater BIS sensitivity was associated with greater NA and greater NA was associated with greater alcohol use. These findings were replicated with alcohol problems. An association also emerged between BAS sensitivity and marijuana use, mediated by PA (95%CIs [-0.296; -0.027]); greater BAS sensitivity was associated with greater PA and greater PA was associated with lower marijuana use. Finally, BIS sensitivity was associated with tobacco use through NA (95%CIs [0.023; 0.325]) and PA (95%CIs [0.004; 0.116]), with NA linked to greater, but PA linked to lower tobacco use. BAS sensitivity was also associated with tobacco use through PA (95%CIs [-0.395; -0.049]), with PA linked again to lower tobacco use.

CONCLUSIONS

There are unique and shared effects of domains of reinforcement sensitivity on adolescent substance use and these vary with index of dispositional affectivity and type of substance considered.

Investigating Self-Control Resource Depletion as a Situational Risk Factor for Aversive Interpartner Communication by Young Adults With ADHD

Objective: Adults with attention-deficit hyperactivity disorder (ADHD) have more conflictual relations with their romantic partners than adults without ADHD. This study investigated whether adults with ADHD are differentially susceptible to conflict when self-control resources are depleted. Method: Heterosexual adult couples (20 including at least one adult with ADHD; 12 including no adults with ADHD) were randomly assigned to have resources temporarily depleted or not. Positive and negative communication was assessed during a subsequent problem-solving task with their partners. Results: Adults with ADHD whose self-control resources were depleted communicated less positively and more negatively with their romantic partners than adults without ADHD whose resources were depleted. Conclusion: Adults with ADHD appear to have a differential susceptibility to interpartner discord when their self-control resources have been depleted. Clinicians seeking to remediate discordant romantic relationships of adults with ADHD should consider evaluating how often their resources needed to manage their impulses are depleted.

Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress

Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to that of controls (non-violent and unaffected), and we also assessed the presence of alexithymia traits and their role in emotional regulation. Our data point out that ADHD IPVAW perpetrators presented higher SCL and negative affect than controls, particularly during the recovery period. Moreover, ADHD IPVAW perpetrators showed higher self-reported alexithymia, and this variable was a good predictor of autonomic and psychological state dysregulations, even after controlling for the effects of alcohol and drug misuse. Therefore, our study reinforces the need to consider psychophysiological measurements when screening the therapeutic needs of IPVAW perpetrators, due to their relatively low cost and the significant contents of their results. Finally, we also highlight the key role of alexithymia in this violent population, which should be considered when designing cognitive intervention training coadjutant to current psychotherapies for IPVAW perpetrators.

Are Mechanical Turk worker samples representative of health status and health behaviors in the U.S.?

Introduction

Amazon’s Mechanical Turk (MTurk) is frequently used to administer health-related surveys and experiments at a low cost, but little is known about its representativeness with regards to health status and behaviors.

Methods

A cross-sectional survey comprised of questions from the nationally-representative 2014 Behavioral Risk Factor Surveillance System (BRFSS) and 2014 National Health and Nutrition Examination Survey (NHANES) was administered to 591 MTurk workers and 393 masters in 2016. Health status (asthma, depression, BMI, and general health), health behaviors (influenza vaccination, health insurance, smoking, and physical activity), and demographic characteristics of the two MTurk populations (workers and masters) were compared to each other and, using Poisson regression, to a nationally-representative BRFSS and NHANES samples.

Results

Workers and master demographics were similar. MTurk users were more likely to be aged under 50 years compared to the national sample (86% vs. 55%) and more likely to complete a college degree than the national sample (50% vs. 26%). Adjusting for covariates, MTurk users were less likely to be vaccinated for influenza, to smoke, to have asthma, to self-report being in excellent or very good health, to exercise, and have health insurance but over twice as likely to screen positive for depression relative to a national sample. Results were fairly consistent among different age groups.

Conclusions

MTurk workers are not a generalizable population with regards to health status and behaviors; deviations did not follow a trend. Appropriate health-related uses for MTurk and ways to improve upon the generalizability of MTurk health studies are proposed.

Crowdsourcing as a method for collecting data pertaining to the effects of alcohol on perceptions of partner aggression

BACKGROUND

Efforts designed to investigate the effects of recent alcohol use on the perception of intimate partner aggression have been stultified by significant financial and logistical barriers that warrant the development of supplemental research methods that may result in more prolific investigation of the phenomenon.

OBJECTIVES

The current study explored the viability of using online crowdsourcing to assess the effects of recent alcohol use on the perception of partner aggression.

METHOD

Mechanical Turk was used to recruit a convenience sample of 60 males who were asked to provide information on their own use of partner aggression, their most recent episode of alcohol use, and their perception of the behaviors and characters depicted in a written partner aggression vignette. Data were evaluated using five separate hierarchical multiple regression models predicting participant perception.

RESULTS

Analyses revealed that 35% of the sample had used partner aggression in the past year and that 22% of the sample had consumed alcohol in the past day. Nonviolent participants perceived the aggressor and the behavior more negatively than partner violent participants. Some indicators revealed that recent alcohol use was associated with more positive perceptions of partner aggression.

CONCLUSION

Expected associations among prior partner aggression, recent alcohol use, and perception of partner aggression vignettes were observed. Crowdsourcing may represent a source for data evaluating the effects of recent alcohol use on perceptions of aggression. Methodological refinement will benefit research and, ultimately, clinical prevention and intervention.

Psychometric Properties of the Impairment Rating Scale in Samples of Adults With Attention Deficit Hyperactivity Disorder

Adults with attention deficit hyperactivity disorder (ADHD) are impaired in numerous domains. However, psychometrically sound measures assessing broad-ranging impairment, particularly brief scales for diagnostic purposes, are scarce. The Impairment Rating Scale (IRS), originally developed to assess ADHD-related impairment in children, has been adapted to a 12-item self-report measure of impairment in adults. In this study, the psychometric properties of the adult IRS were examined in three samples. In Studies 1 and 2, the adult IRS demonstrated good convergent, divergent, and incremental validity among college students and an online sample of adults, respectively. In the same studies, an appropriate clinical cutoff score was identified (IRS item score ≥1) using diagnostic tests. In Study 3, the adult IRS demonstrated good interrater reliability between ratings provided by romantic partners. Overall, findings support the clinical utility of the adapted IRS for assessing the impairment diagnostic criterion for ADHD in adults.
