Adverse childhood experiences (ACEs) have been associated with a range of physical and mental health problems, and it is now understood that the developmental timing of ACEs may be critically important. Despite this, there is a distinct lack of methods for the efficient assessment of such timing in research and clinical settings. We report on the development and validation of a new measure, the Adverse Life Experiences Scale (ALES), that indexes such developmental timing within a format incorporating caregivers’ reports of ACEs in their own lives and those of their children. Participants were a nationally representative sample of Australian families (n = 515; Study 1), and a sample of clinic-referred families (n = 168; Study 2). Results supported the internal consistency and test–retest reliability of the ALES and indicated high levels of acceptability for the measure. In terms of validity, ALES scores were significantly associated with interview-based measures of child maltreatment and quality of the family environment, as well as measures of psychopathology across multiple informants (parents, teachers, clinician-rated). Furthermore, indices of ACEs occurring within specific age-based periods of childhood were found to explain unique variance in current symptoms of child and caregiver psychopathology, independent of the overall chronicity of those ACEs and current adversity.

Children with conduct problems and high callous-unemotional (CP+CU) traits are characterized by dampened emotional responding, limiting their ability for affective empathy and impacting the development of prosocial behaviors. However, research documenting this dampening in young children is sparse and findings vary, with attachment-related stimuli hypothesized to ameliorate deficits in emotional responding. Here we test emotional responsiveness across various emotion-eliciting stimuli using multiple measures of emotional responsiveness (behavioral, physiological, self-reported) and attention, in young children aged 2–8 years (M age = 5.37), with CP+CU traits (CP+CU; n = 36), CPs and low CU traits (CP−CU; n = 82) and a community control sample (CC; n = 27). We found no evidence that attachment-related stimulus ameliorated deficits in emotional responding. Rather, at a group level we found a consistent pattern of reduced responding across all independent measures of responsiveness for children with CP+CU compared to the CC group. Few differences were found between CP+CU and CP−CU groups. When independent measures were standardized and included in a regression model predicting to CU trait score, higher CU traits were associated with reduced emotional responding, demonstrating the importance of multimodal measurement of emotional responsiveness when investigating the impact of CU traits in young children.

High comorbidity and an overlap in symptomology have been demonstrated between dyslexia and visual stress. Several researchers have hypothesized an underlying or causal influence that may account for this relationship. The magnocellular theory of dyslexia proposes that a deficit in visuo-temporal processing can explain symptomology for both disorders. If the magnocellular theory holds true, individuals who experience symptomology for these disorders should show impairment on a visuo-temporal task, such as driving. Eighteen male participants formed the sample for this study. Self-report measures assessed dyslexia and visual stress symptomology as well as participant IQ. Participants completed a drive simulation in which errors in response to road signs were measured. Bivariate correlations revealed significant associations between scores on measures of dyslexia and visual stress. Results also demonstrated that self-reported symptomology predicts magnocellular impairment as measured by performance on a driving task. Results from this study suggest that a magnocellular deficit offers a likely explanation for individuals who report high symptomology across both conditions. While conclusions about the impact of these disorders on driving performance should not be derived from this research alone, this study provides a platform for the development of future research, utilizing a clinical population and on-road driving assessment techniques.
