Childhood adversity (CA) is commonly associated with an increased risk of subsequent psychopathology. It is important to identify potential mediators of this relationship which can allow for the development of interventions. In a large population-based cohort study we investigated the relationship between CA and late adolescent psychopathology and early adolescent candidate mediators of this relationship.

We used data from three waves (n = 6039) of Cohort 98′ of the Growing up in Ireland Study (age 9, 13 and 17). We used doubly robust counterfactual analyses to investigate the relationship between CA (reported at age-9) with psychopathology (internalizing and externalizing problems), measured using the Strengths and Difficulties Questionnaire at age-17. Counterfactual and traditional mediation was used to investigate the mediating effects of the parent-child relationship, peer relations, self-concept, computer usage and physical activity.

CA was associated with an increased risk of internalizing and externalizing problems at age-17. Parent-child conflict mediated 35 and 42% of the relationship between CA and late adolescent externalizing problems and internalizing problems, respectively. Self-concept and physical activity mediated an additional proportion of the relationship between CA and internalizing problems. These results were robust to unmeasured confounding.

Parent-child conflict explains more than a third of the relationship between CA and later psychopathology. Self-concept and physical activity explain the additional proportion of the relationship between CA and internalizing problems. This suggests that these factors may be good targets for intervention in young people who have experienced CA to prevent subsequent psychopathology.

Assessment of risks of illnesses has been an important part of medicine for decades. We now have hundreds of ‘risk calculators’ for illnesses, including brain disorders, and these calculators are continually improving as more diverse measures are collected on larger samples.

We first replicated an existing psychosis risk calculator and then used our own sample to develop a similar calculator for use in recruiting ‘psychosis risk’ enriched community samples. We assessed 632 participants age 8–21 (52% female; 48% Black) from a community sample with longitudinal data on neurocognitive, clinical, medical, and environmental variables. We used this information to predict psychosis spectrum (PS) status in the future. We selected variables based on lasso, random forest, and statistical inference relief; and predicted future PS using ridge regression, random forest, and support vector machines.

Cross-validated prediction diagnostics were obtained by building and testing models in randomly selected sub-samples of the data, resulting in a distribution of the diagnostics; we report the mean. The strongest predictors of later PS status were the Children's Global Assessment Scale; delusions of predicting the future or having one's thoughts/actions controlled; and the percent married in one's neighborhood. Random forest followed by ridge regression was most accurate, with a cross-validated area under the curve (AUC) of 0.67. Adjustment of the model including only six variables reached an AUC of 0.70.

Results support the potential application of risk calculators for screening and identification of at-risk community youth in prospective investigations of developmental trajectories of the PS.

On-call and crisis psychiatry is a very challenging aspect of psychiatric training. This study aimed to describe the experiences of psychiatric trainees on-call in hospitals, emergency departments and psychiatric units in Ireland.

In total, 193 psychiatric trainees in Ireland were emailed a survey in 2017. The survey included questions regarding the duties expected of the trainee, frequency of on-call obligations, un-rostered hours worked, level of senior support, assessment facilities available and doctors’ satisfaction with the on-call experience.

Overall, 68 trainees responded to the survey. In total, 35% of respondents reported dissatisfaction with their experience of on-call and crisis psychiatry, 46% reported that they were not provided with training in risk assessment and 21% of respondents stated that there was not a suitable room available to perform their assessments.

This survey has raised important issues facing those on the frontline of psychiatric services in Ireland. Of particular concern are resource issues faced by trainees and the need for further training and support related to risk assessment when on-call. Remedying these issues may lead to a decreased rate of dropout as well as a safer and better environment for patients and doctors alike.

There is a high rate of psychiatric comorbidity in patients with epilepsy. However, the impact of surgical treatment of refractory epilepsy on psychopathology remains under investigation. We aimed to examine the impact of epilepsy surgery on psychopathology and quality of life at 1-year post-surgery in a population of patients with epilepsy refractory to medication.

This study initially assessed 48 patients with refractory epilepsy using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life in Epilepsy Inventory 89 (QOLIE-89) on admission to an Epilepsy Monitoring Unit (EMU) as part of their pre-surgical assessment. These patients were again assessed using the SCID-I, QOLIE-89 and HADS at 1-year follow-up post-surgery.

There was a significant reduction in psychopathology, particularly psychosis, following surgery at 1-year follow-up (p < 0.021). There were no new cases of de novo psychosis and surgery was also associated with a significant improvement in the quality of life scores (p < 0.001).

This study demonstrates the impact of epilepsy surgery on psychopathology and quality of life in a patient population with refractory surgery. The presence of a psychiatric illness should not be a barrier to access surgical treatment.

To determine if the initial COVID-19 societal restrictions, introduced in Ireland in March 2020, impacted on the number and nature of psychiatry presentations to the emergency department (ED) of a large academic teaching hospital.

We examined anonymised clinical data of psychiatry presentations to the ED during the initial 8-week period of COVID-19 restrictions. Data from corresponding 8-week periods in 2018 and 2019 were also extracted for comparison.

Psychiatry presentations to ED reduced by 21% during the COVID-19 restrictions, from 24/week to 19/week when compared with corresponding periods in 2018/2019 (Poisson’s Rate Test estimate of difference −5.2/week, 95% CI 1.3–9.1, p = 0.012). Numbers attending for out-of-hours assessment remained unchanged (81 v. 80), but numbers seeking assessment during normal hours decreased (71 v. 114). We observed increased presentations from the <18 age group, but decreased presentations from the 18 to 29 age group (Pearson’s Chi-Square 20.363, df = 6, p = 0.002). We recorded an increase in anxiety disorders during the initial COVID-19 restrictions (31 v. 23), and a reduction in alcohol disorders (28 v. 52). The proportion of presentations with suicidal ideation (SI) or self-harm as factors remained unchanged.

Rates of emergency presentation with mental illness reduced during the initial COVID-19 restrictions. This may represent an unmet burden of mental health needs. Younger people may be experiencing greater distress and mental illness during the current crisis. More people sought help for anxiety disorders during the COVID-19 restrictions compared with corresponding data from 2018 and 2019.

Abnormal body mass index (BMI) has been associated with development of psychopathology. This association in children is well documented, for both overweight and underweight children. However, the association between change in BMI and the development of psychopathology has been less investigated.

To investigate the association between change in BMI between childhood and adolescence and psychopathology in adolescence.

Data from the Growing Up in Ireland cohort were used. We investigated the ’98 cohort (also known as the child cohort) at age 9/13. BMI, defined using internationally recognised definitions as underweight, healthy or overweight, was used as the exposure, and abnormal Strength and Difficulties Questionnaire scores were used as the outcome. Logistic regression was undertaken for the analysis. All analyses were adjusted for confounders.

A change to overweight from healthy BMI was significantly associated with increased risk of psychopathology (adjusted OR 1.66; 95% CI 1.19–2.32). Both change from underweight to healthy (adjusted OR 0.12; 95% CI 0.03–0.43) or from overweight to healthy (adjusted OR 0.47; 95% CI 0.79–0.8) was associated with a significantly reduced risk of developing psychopathology.

As a child’s BMI returns to within the healthy range, their risk of adolescent psychopathology is reduced. Interventions to restore healthy BMI, in both underweight and overweight, children may reduce their risk of adolescent psychopathology.

Often referred to as psychotic experiences, unusual perceptual experiences, thoughts and beliefs (UPTBs) are not uncommon in youth populations. Phenomenological studies of these experiences are lacking. This study aimed to (1) describe the phenomenological characteristics of UPTBs in a sample of young adolescents and (2) explore how young people made sense of those experiences.

Participants were 53 young people aged 11–13 years from a population-based study of mental health. All met criteria for UPTBs following clinical interviews as part of the study. Documentary data on UPTBs in the form of transcribed notes, recorded during clinical interviews, were analysed using content analysis. Data on UPTBs were coded, organised into categorical themes and quantified using descriptive statistics. Qualitative themes on how participants made sense of their experiences were identified.

Participants reported UPTBs across four domains: auditory verbal, auditory non-verbal, non-auditory perceptual experiences and unusual thoughts and beliefs. UPTBs were phenomenologically rich and diverse. Young people sought to make sense of their experiences in multiple ways: normalising them, externalising them by attributing them to paranormal entities and distancing them from psychiatric explanations. Uncertainty about the source of UPTBs was identified as a superordinate theme.

Findings from this study offer new insights into the phenomenological qualities and characteristics of UPTBs in young adolescents. They also reveal that early adolescents may not make sense of their experiences within a psychiatric framework. These findings highlight the need to develop a more phenomenologically sensitive and nuanced approach to studying UPTBs in young people.

Individuals who report psychotic-type experiences are at increased risk of future clinical psychotic disorder. They constitute a ‘at-high risk’ group for studying the trajectory to schizophrenia and related illnesses. Psychotic disorders are a significant risk factor for suicide, especially young people. Previous research has used screening instruments to identify this high risk group but few studies have followed up by an in-depth clinical interview to assess the relationship between psychotic symptoms and suicidality or other psychopathology.

As part of a community study, a 50-minute self -reported screening questionnaire which included one item designed to assess psychotic symptoms (auditory hallucinations) was administered to 900 adolescents aged 14 years in community schools, in Cork, Ireland. The following question (“Have you ever heard voices or sounds that no one else can hear?”) was used as it has been shown previously to have best predictive power (Kelleher., 2009). Other screening questions assessed suicidality and other psychopathology. Detailed clinical interviews by experienced child and adolescent psychiatrists were subsequently carried out with some of these adolescents who endorsed a positive answer to screening questions.

We plan to calculate the sensitivity and specificity and positive predictive value for the specific screening symptom on auditory hallucinations and its relationship to psychopathology as verified on clinical interview.

Our results will be of value to those engaged in treating children and adolescents with psychiatric disorder and will inform on the clinical significance of a positive answer to a screening question on auditory hallucinations in adolescence.
