Evaluating a scale of excessive mind wandering among males and females with and without attention-deficit/hyperactivity disorder from a population sample

Recent studies highlight the role of excessive mind wandering in attention-deficit/hyperactivity disorder (ADHD) and its association with impairment. We believe assessing mind wandering could be especially relevant to individuals, including many females, who present with less externalising manifestations of ADHD. Using a new measure based on ADHD patient reports, the Mind Excessively Wandering Scale (MEWS), we previously found adults with ADHD had elevated levels of mind wandering that contributed to impairment independently of core ADHD symptoms. Using data from an online general population survey, the current study assessed the factor-structure, reliability, validity and measurement invariance of the MEWS. We also investigated sex differences in mind wandering, as well as ADHD symptoms, impairment and wellbeing in those with and without ADHD. The MEWS had a unidimensional structure, was invariant across sex, age and ADHD status, and accounted for unique variance in impairment and wellbeing beyond core ADHD symptoms. Among those with ADHD, we found no evidence for sex differences in mind wandering and among those without ADHD males had higher scores. We also found similar levels of hyperactivity/impulsivity, emotional lability, and impairment in males and females with ADHD, but males reported greater inattention and lower wellbeing. Results suggest the MEWS is a reliable and valid instrument measuring the same construct across sex, age and ADHD status, which could aid diagnosis and monitoring of outcomes

Bullying behaviours and other conduct problems: longitudinal investigation of their independent associations with risk factors and later outcomes

Purpose Bullying behaviours and other conduct problems often co-occur. However, we do not yet know whether bullying behaviours are associated with early factors and later poor outcomes independently of conduct problems. While there are difering, specifc interventions for bullying behaviours and for conduct problems, it is unclear if such specifcity is justifed given parallels between both behaviours. Methods We used prospective data from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative sample of 2232 children. Mothers and teachers reported on children’s bullying behaviours and conduct problems at ages 7 and 10. We collected measures of risk factors, including temperament and family factors, when children were age 5. We assessed behavioural, emotional, educational and social problems when participants reached the ages of 12 and 18. Results Bullying behaviours and conduct problems co-occurred in childhood. Our fndings indicated that bullying behaviours and other conduct problems were independently associated with the same risk factors. Furthermore, they were associated with the same poor outcomes at both ages 12 and 18. Despite this, bullying behaviours were uniquely associated with behavioural, emotional, educational and social problems at age 18. Conclusions Our fndings suggest that anti-bullying programmes and interventions aimed at reducing conduct problems could beneft from greater integration. Furthermore, our study highlights the mental health problems children who bully may face in later years and the need to consider those in intervention plans

The intergenerational association between parents' problem gambling and impulsivity-hyperactivity/inattention behaviors in children

Despite the well-established association between problem gambling and ADHD core categories of impulsivity-hyperactivity and inattention, the link between parents’ problem gambling and impulsivity-hyperactivity/inattention (IH/I) behaviors in children has not been investigated. This study investigated the association between parents’ problem gambling and children’s IH/I behaviors while controlling for potential confounding variables. A population-based prospective cohort followed-up from kindergarten to age 30, the Quebec Longitudinal Study of Kindergarten Children (QLSKC), provided data over three generations. Among 1358 participants at age 30, parents with a child aged 1 year or older (N=468; Mean age=4.65 years; SD=2.70) were selected. Generalized Linear Models included measures of grandparents’ and parents’ problem gambling, parents’ IH/I behaviors in childhood, and a host of risk factors and comorbidities to predict IH/I in children. Intergenerational bivariate associations were observed between grandparents’ problem gambling, parents’ IH/I in childhood and problem gambling at age 30, and between parents’ IH/I, problem gambling, and children’s IH/I behaviors. Parents’ problem gambling predicted children’s IH/I behaviors above and beyond the effects of covariates such as family and socioeconomic characteristics, alcohol and drug use, depression symptoms and parents’ gambling involvement. Parents’ IH/I behaviors in childhood also predicted children’s IH/I and had a moderating, enhancing effect on parents’ problem gambling association with their offspring’s IH/I behaviors. Problem gambling is a characteristic of parents’ mental health that is distinctively associated with children’s IH/I behaviors, above and beyond parents’ own history of IH/I and of typically related addictive, psychopathological or socioeconomic risk factors and comorbidities

Identifying and evaluating field indicators of urogenital schistosomiasis-related morbidity in preschool-aged children

BACKGROUND:Several studies have been conducted quantifying the impact of schistosome infections on health and development in school-aged children. In contrast, relatively little is known about morbidity levels in preschool-aged children (≤ 5 years) who have been neglected in terms of schistosome research and control. The aim of this study was to compare the utility of available point-of-care (POC) morbidity diagnostic tools in preschool versus primary school-aged children (6-10 years) and determine markers which can be used in the field to identify and quantify Schistosoma haematobium-related morbidity. METHODS/PRINCIPAL FINDINGS:A comparative cross-sectional study was conducted to evaluate the performance of currently available POC morbidity diagnostic tools on Zimbabwean children aged 1-5 years (n=104) and 6-10 years (n=194). Morbidity was determined using the POC diagnostics questionnaire-based reporting of haematuria and dysuria, clinical examination, urinalysis by dipsticks, and urine albumin-to-creatinine ratio (UACR). Attributable fractions were used to quantify the proportion of morbidity attributable to S. haematobium infection. Based on results of attributable fractions, UACR was identified as the most reliable tool for detecting schistosome-related morbidity, followed by dipsticks, visual urine inspection, questionnaires, and lastly clinical examination. The results of urine dipstick attributes showed that proteinuria and microhaematuria accounted for most differences between schistosome egg-positive and negative children (T=-50.1; p<0.001). These observations were consistent in preschool vs. primary school-aged children. CONCLUSIONS/SIGNIFICANCE:Preschool-aged children in endemic areas can be effectively screened for schistosome-related morbidity using the same currently available diagnostic tools applicable to older children. UACR for detecting albuminuria is recommended as the best choice for rapid assessment of morbidity attributed to S. haematobium infection in children in the field. The use of dipstick microhaematuria and proteinuria as additional indicators of schistosome-related morbidity would improve the estimation of disease burden in young children

COVID-19 and Perceived Changes to Quality of Life, Anxiety, Depression, and Loneliness in Autistic and Other Neurodivergent U.K. Adults

BACKGROUND: In the United Kingdom, we have experienced many changes to our daily lives as a result of COVID-19. Autistic and other neurodivergent (ND, e.g., those with attention-deficit hyperactivity disorder) adults may be more vulnerable to negative effects of the pandemic due to pre-existing mental health disparities and unmet support needs. Furthermore, there is little research, either pandemic related or otherwise, which considers how the experiences of autistic adults with additional intersecting ND identities might differ from those without. METHODS: We collected data from an online survey during June 2020 to September 2020 to explore the psychological impact of the coronavirus pandemic on U.K. adults (N = 286, age 18-72 years). Participants included neurotypical (NT) adults (N = 98), autistic adults (N = 73), other ND adults (N = 53), as well as autistic adults with an additional intersecting ND identity (N = 63). We measured and compared levels of quality of life (QoL), depression, anxiety, and loneliness across groups as well as perceived change in these as a result of the pandemic. RESULTS: Autistic adults, with and without additional ND identities, had consistently low QoL and high anxiety, depression, and loneliness compared with NT adults. We found no differences in these areas between autistic adults with and without additional intersecting ND identities. In some areas, non-autistic ND participants were also doing poorly compared with their NT peers. Many participants felt that their QoL, mental health, and loneliness had worsened due to the pandemic, and this was largely similar across groups. CONCLUSIONS: These results highlight that COVID-19 may have led to increased need and demand for mental health services across the U.K. adult population. Both autistic and ND adults may be in particular need of increased (and improved) mental health and well-being support. This is likely because of pre-existing differences in mental health and well-being as well as individuals facing further difficulties as a result of the pandemic
