Objective: Research shows that alcohol use is linked to suicidal ideation (SI), while depression is strongly associated with SI. Protective behavioral strategies (PBS) are safe drinking strategies. PBS are broadly protective across alcohol-related problems; however, it is unclear if these effects extend to those at risk for SI. We hypothesized…

Background: Accumulating evidence suggests that sleep disordered breathing (SDB) is under-recognized in youth and adults with ADHD. SDB may contribute to exacerbating pre-existing ADHD symptoms and may play a role in the development of cognitive deficits that may mimic ADHD symptoms. Method: We conducted a focused review of publications on…

Developmental language disorder (DLD) is a language deficit affecting approximately 7% of the general population and does not associate with any hearing impairment, neurological damage, or mental disorder. In DLD, the complications arise over time due to the learning difficulties experienced, which causes eventual cognitive delay compared to…

Adults with Down syndrome (DS) experience high risk for Alzheimer's disease (AD), but there is variability in the timing of transition from a cognitively stable state to prodromal AD and dementia. The present study examined the association between a modifiable lifestyle factor, employment complexity, and cognitive decline across two time points in…

The current study investigated longitudinal associations between parent-rated temperament, observed exuberance and accelerometer activity level at 18-months and symptoms of ASD and ADHD at 36-months in a sample of 54 children at elevated likelihood for ASD. For the specific parent-rated temperament scales, most observed significant associations…

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

Victimization during school years can have detrimental effects on individuals' adjustment, lasting even into adulthood. In the current study, we examine whether there is an indirect effect of victimization on adult depression and aggression, via sad and angry rumination about past victimization. Participants included 1,319 Finnish individuals…

Background: Research has demonstrated that parent-child attachment security and school connectedness (SC) are protective factors against substance use, depression, and suicidality during adolescence. However, past research has examined these factors independently, and little is known about how attachment security and SC work in conjunction to…

Objective: Adolescents and young adults are at risk for non-suicidal self-injury (NSSI) and suicidal behavior. This study examined intrapersonal (depressive symptoms, self-criticism) and family (perceived family functioning, parenting style, parental attachment) factors associated with reported history of NSSI in a college sample. Method:…

An emerging literature base suggests that symptoms of oppositional defiant disorder (ODD) persist beyond adolescence and are associated with unique psychosocial impairment for adult populations. The purpose of this study is to examine the clinical characteristics of ODD symptoms in a young adult population. Three-hundred and five young adult…

Objective: To test associations between viewing "13 Reasons Why," Season 1 and past week suicide ideation severity, behavior risk, stigma, and knowledge in college students. To explore whether personal exposure to suicide and depressive symptom severity moderated these associations. Participants: Eight-hundred and eighteen college…

Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally…

Research attempting to identify pathways from childhood maltreatment to adulthood posttraumatic stress symptoms (PTSS) implicates cognitive vulnerabilities that may increase risk for mental health concerns. The present study examined two cognitive vulnerabilities and their relation to PTSS amongst individuals with and without childhood…

Previous research assessing consequences of interpregnancy intervals (IPIs) on child development is mixed. Utilizing a population-based US sample (n = 5339), we first estimate the associations between background characteristics (e.g. sociodemographic and maternal characteristics) and short ([less than or equal to]1 year) and long (>3 years)…

Background: Dialectical behaviour therapy for adolescents (DBT-A) has recently been adapted and tested as an intervention for suicidal youth in randomized trials. Although studies have demonstrated the efficacy of this intervention for suicidal behaviours, research examining which youth get offered DBT-A in clinical practice is lacking. Objective:…
