Let's Set Up Some Subgoals: Understanding Human-Pedagogical Agent Collaborations and Their Implications for Learning and Prompt and Feedback Compliance

International audienceResearch on collaborative learning between humans and virtual pedagogical agents represents a necessary extension to recent research on the conceptual, theoretical, methodological, analytical, and educational issues behind co-and socially-shared regulated learning between humans. This study presents a novel coding framework that was developed and used to describe collaborations between learners and a pedagogical agent (PA) during a subgoal setting activity with MetaTutor, an intelligent tutoring system. Learner-PA interactions were examined across two scaffolding conditions: prompt and feedback (PF), and control. Learners' compliance to follow the PA's prompts and feedback in the PF condition were also examined. Results demonstrated that learners followed the PA's prompts and feedback to help them set more appropriate subgoals for their learning session the majority of the time. Descriptive statistics revealed that when subgoals were set collaboratively between learners and the PA, they generally lead to higher proportional learning gains when compared to less collaboratively set goals. Taken together, the results provide preliminary evidence that learners are both willing to engage in and benefit from collaborative interactions with PAs when immediate, directional feedback and the opportunity to try again are provided. Implications and future directions for extending co-and socially-shared regulated learning theories to include learner-PA interactions are proposed

The Mental Health of Young People in Ireland: A report of the Psychiatric Epidemology Research across the Lifespan (PERL) Group

There is increasing concern about the mental health of young people in Ireland. Reports of psychological distress, substance abuse and suicide among Irish youths have become common. While we know that many young people in Ireland are experiencing mental distress, little research has been done to determine the actual number of young people who are experiencing a diagnosable mental disorder. This report goes some way towards addressing this issue by presenting findings from two research studies that have used clinical interview assessments to establish the rate of diagnosable mental disorders among Irish adolescents and young adults. These studies, funded by the Health Research Board, are part of a broader programme of research by the Psychiatric Epidemiology Research across the Lifespan (PERL) Group in the Department of Psychiatry, Royal College of Surgeons in Ireland (RCSI). The findings in this report have relevance for young people, parents, teachers, health professionals, allied health professionals and any other individuals or groups who are concerned about the mental health of young people. They provide essential information to inform healthcare policy and to guide the development of high quality, accessible and responsive mental health services for any young person who needs them. They also highlight the need to ensure that we, as a society, are committed to the protection and promotion of young people’s mental health

Psychotic symptoms in adolescence index risk for suicidal behavior: findings from 2 population-based case-control clinical interview studies.

CONTEXT: Recent evidence from both clinical and population research has pointed to psychotic symptoms as potentially important markers of risk for suicidal behavior. However, to our knowledge, there have been no epidemiological studies to date that have reported data on psychotic symptoms and suicidality in individuals who have been clinically assessed for suicidal behavior. OBJECTIVES: To explore associations between psychotic symptoms in nonpsychotic adolescents and risk for suicidal behavior in (1) the general population, (2) adolescents with psychiatric disorder, and (3) adolescents with suicidal ideation. DESIGN Two independently conducted case-control clinical interview studies. SETTING Population-based studies in Ireland. PARTICIPANTS Study 1 included 212 adolescents aged 11 to 13 years. Study 2 included 211 adolescents aged 13 to 15 years. Participants were recruited from schools. MAIN OUTCOME MEASURES: Suicidal behavior and psychotic symptoms, assessed by semi-structured diagnostic clinical interview. RESULTS Psychotic symptoms were associated with a 10-fold increased odds of any suicidal behavior (ideation, plans, or acts) in both the early and middle adolescence studies (odds ratio [OR], 10.23; 95% CI, 3.25-32.26; P \u3c .001 and OR, 10.5; 95% CI, 3.14-35.17; P \u3c .001, respectively). Adolescents with depressive disorders who also experienced psychotic symptoms were at a nearly 14-fold increased odds of more severe suicidal behavior (suicide plans and suicide acts) compared with adolescents with depressive disorders who did not experience psychotic symptoms (OR, 13.7; 95% CI, 2.1-89.6). Among all adolescents with suicidal ideation, those who also reported psychotic symptoms had a nearly 20-fold increased odds of suicide plans and suicide acts compared with adolescents with suicidal ideation who did not report psychotic symptoms (OR, 19.6; 95% CI, 1.8-216.1). CONCLUSIONS: Psychotic symptoms are strongly associated with increased risk for suicidal behavior in the general adolescent population and in adolescents with (nonpsychotic) psychiatric disorder. In both studies, an absolute majority of adolescents with more severe suicidal behavior (suicidal plans and acts) reported psychotic symptoms when directly questioned about this as part of a psychiatric interview. Assessment of psychotic symptoms should form a key part of suicide risk assessment

Identification and characterization of prodromal risk syndromes in young adolescents in the community: a population-based clinical interview study.

While a great deal of research has been conducted on prodromal risk syndromes in relation to help-seeking individuals who present to the clinic, there is a lack of research on prodromal risk syndromes in the general population. The current study aimed first to establish whether prodromal risk syndromes could be detected in non-help-seeking community-based adolescents and secondly to characterize this group in terms of Axis-1 psychopathology and general functioning. We conducted in-depth clinical interviews with a population sample of 212 school-going adolescents in order to assess for prodromal risk syndromes, Axis-1 psychopathology, and global (social/occupational) functioning. Between 0.9% and 8% of the community sample met criteria for a risk syndrome, depending on varying disability criteria. The risk syndrome group had a higher prevalence of co-occurring nonpsychotic Axis-1 psychiatric disorders (OR = 4.77, 95% CI = 1.81-12.52; P \u3c .01) and poorer global functioning (F = 24.5, df = 1, P \u3c .0001) compared with controls. Individuals in the community who fulfill criteria for prodromal risk syndromes demonstrate strong similarities with clinically presenting risk syndrome patients not just in terms of psychotic symptom criteria but also in terms of co-occurring psychopathology and global functioning

Nonsuicidal self-injury, suicidal thoughts and suicide attempts among sexual minority youth in Ireland during their emerging adult years.

AIM: This study aimed to examine whether or not sexual minority youth constitute an at-risk group for nonsuicidal self-injury, suicidal ideation or suicide attempts during their emerging adult years. METHODS: Using data from the Challenging Times Study, a population-based study of psychopathology and suicide in Ireland, analyses were conducted to test the associations between sexual minority status and the odds of any lifetime experience of nonsuicidal self-injury, suicidal thoughts or suicide attempts among Irish youth aged 19-24 years. RESULTS: Sexual minority youth had 6.6-fold (95% CI 1.7-24.7) increased risk of nonsuicidal self-injury, a 5.0-fold (95% CI 1.3-18.3) increased risk of suicidal ideation, a 7.7-fold (95% CI 1.8-32.0) increased risk of suicide intent and a 6.8-fold (95% CI 1.6-27.6) increased risk of a suicide attempt during their lifetime compared to their heterosexual peers. CONCLUSIONS: This study shows that emerging adulthood is a period of risk for suicide and nonsuicidal self-injurious behaviour among sexual minority youth

Evaluation of the Music Engagement Program for people with Alzheimer's disease and dementia: Study protocol for a pilot trial

Background Alzheimer's disease and dementia are prevalent conditions globally. People with Alzheimer's disease and dementia commonly experience mental health problems, negative emotional states, and behavioural disturbance. Music therapy has previously been used in this population to improve symptoms of mental health problems; however, there is a paucity of evidence-based programs that also explore positive outcomes such as overall quality of life, social outcomes, as well as the acceptability and sustainability of these programs. Aims This project aims to evaluate the effectiveness of the specialised Music Engagement Program (MEP) in improving quality of life, wellbeing, and depression symptoms, in aged-care residents with Alzheimer's disease and dementia. The project also aims to explore how the MEP could be applied and maintained on a broader level throughout the aged-care community. Methods The intervention will take place over 8 weeks in an aged-care facility for people living with dementia in Canberra, Australia. Weekly 45-60-min group singing sessions will be led by a music facilitator. Results The results of the study will be submitted for publication in relevant academic journals and mental health conferences, disseminated to participants on request, to the residential care facility, and via the lead researcher's website. Conclusions This study can provide an indication of the feasibility of the MEP in enhancing the mental health and wellbeing of individuals with Alzheimer's disease and dementia. Further investigation will be required to establish the MEP's ability to be maintained on an ongoing basis with minimal costs and administrative support.This project is supported by a 2017 Excellence in Population Health Research Award, Research School of Population Health, ANU (AG, MP), and by funding provided by ACT Health for ACACIA: The ACT Consumer and Carer Mental Health Research Unit. The project is also supported by in-kind resources from the Centre for Mental Health Research, ANU.

Prevalence of psychotic symptoms in childhood and adolescence: a systematic review and meta-analysis of population-based studies.

BACKGROUND: Psychotic symptoms occur more frequently in the general population than psychotic disorder and index risk for psychopathology. Multiple studies have reported on the prevalence of these symptoms using self-report questionnaires or clinical interviews but there is a lack of consensus about the prevalence of psychotic symptoms among children and adolescents.MethodWe conducted a systematic review of all published literature on psychotic symptom prevalence in two age groups, children aged 9-12 years and adolescents aged 13-18 years, searching through electronic databases PubMed, Ovid Medline, PsycINFO and EMBASE up to June 2011, and extracted prevalence rates. RESULTS: We identified 19 population studies that reported on psychotic symptom prevalence among children and adolescents. The median prevalence of psychotic symptoms was 17% among children aged 9-12 years and 7.5% among adolescents aged 13-18 years. CONCLUSIONS: Psychotic symptoms are relatively common in young people, especially in childhood. Prevalence is higher in younger (9-12 years) compared to older (13-18 years) children

Differences in Life-Saving Obstetric Hemorrhage Treatments for Women with Abortion Versus Nonabortion Etiologies in Tanzania.

Complications from unsafe abortion are among the major causes of preventable maternal morbidity and mortality, which may be compounded by delays and disparities in treatment. We conducted a secondary analysis of women with symptoms of hypovolemic shock secondary to severe obstetric hemorrhage in Tanzania. We compared receipt of three lifesaving interventions among women with abortions versus other maternal hemorrhage etiologies. Interventions included: non-pneumatic anti-shock garment (NASG) (N = 393), blood transfusion (N = 249), and referral to a higher-capacity facility (N = 131). After controlling for severity of disease and other confounders, women with abortion-related hemorrhage and shock had 78 percent decreased odds of receiving NASG (p < 0.001) and 77 percent decreased odds of receiving a blood transfusion (p < 0.001) compared to women with hemorrhage and shock from other etiologies. Our findings suggest that, in Tanzania, women with abortion-related hemorrhage received lower quality of care than women with other hemorrhage etiologies

Prenatal Exposure to Organophosphate Pesticides and IQ in 7-Year-Old Children

Context: Organophosphate (OP) pesticides are neurotoxic at high doses. Few studies have examined whether chronic exposure at lower levels could adversely affect children’s cognitive development
