RESUMEN

Previous investigations on the causal neural mechanisms underlying intertemporal decision making focused on the dorsolateral prefrontal cortex as neural substrate of cognitive control. However, little is known, about the causal contributions of further parts of the frontoparietal control network to delaying gratification, including the pre-supplementary motor area (pre-SMA) and posterior parietal cortex (PPC). Conflicting previous evidence related pre-SMA and PPC either to evidence accumulation processes, choice biases, or response caution. To disentangle between these alternatives, we combined drift diffusion models of decision making with online transcranial magnetic stimulation (TMS) over pre-SMA and PPC during an intertemporal decision task. While we observed no robust effects of PPC TMS, perturbation of pre-SMA activity reduced preferences for larger over smaller rewards. A drift diffusion model of decision making suggests that pre-SMA increases the weight assigned to reward magnitudes during the evidence accumulation process without affecting choice biases or response caution. Taken together, the current findings reveal the computational role of the pre-SMA in value-based decision making, showing that pre-SMA promotes choices of larger, costly rewards by strengthening the sensitivity to reward magnitudes.

RESUMEN

BACKGROUND: Numerous studies have demonstrated the effectiveness of digital interventions for improving the mental health of university students. However, low rates of engagement with these interventions are an ongoing challenge and can compromise effectiveness. Brief, transdiagnostic, web-based video interventions are capable of targeting key mental health and related issues affecting university students and may be more engaging and accessible for this population. OBJECTIVE: This study used a 2-arm randomized controlled trial to evaluate the effectiveness of Uni Virtual Clinic-Lite (UVC-Lite), a fully automated, transdiagnostic, web-based video intervention, relative to an attention-control condition. The primary outcomes were symptoms of depression and generalized anxiety disorder. The secondary outcomes included psychological distress, social anxiety symptoms, body appreciation, quality of life, well-being, functioning, general self-efficacy, academic self-efficacy, and help seeking. Program use (intervention uptake and engagement) and satisfaction were also assessed. METHODS: University students (n=487) with mild to moderate symptoms of distress were recruited from universities across Australia and randomly allocated to receive access to the UVC-Lite intervention or an attention-control condition targeting general health for a period of 6 weeks. UVC-Lite includes 12 modules, each comprising a brief animated video and an accompanying exercise. Of the 12 modules, 7 also included a brief symptom screening quiz. Outcomes were assessed at baseline, postintervention, and 3- and 6-months postintervention. RESULTS: The primary and secondary outcomes were analyzed on an intention-to-treat basis using mixed models repeated measures ANOVA. The intervention was not found to be effective relative to the control condition on any of the primary or secondary outcomes. While 67.9% (114/168) of participants accessed at least 1 module of the intervention, module completion was extremely low. Subgroup analyses among those who engaged with the program (completed at least 1 video) and those with higher baseline distress (Distress Questionnaire-5 score ≥15) did not reveal any differences between the conditions over time. However, uptake (accessing at least 1 video) and engagement (completing at least 1 video) were higher among those with higher baseline symptoms. Satisfaction with the intervention was high. CONCLUSIONS: The UVC-Lite intervention was not effective relative to a control program, although it was associated with high satisfaction among students and was not associated with symptom deterioration. Given the challenges faced by universities in meeting demand for mental health services, flexible and accessible interventions such as UVC-Lite have the potential to assist students to manage symptoms of mental health problems. However, low uptake and engagement (particularly among students with lower levels of symptomatology) are significant challenges that require further attention. Future studies should examine the effectiveness of the intervention in a more highly symptomatic sample, as well as implementation pathways to optimize effective engagement with the intervention.

RESUMEN

Globally, tertiary education has been greatly affected by the Covid-19 crisis. In this essay we explore the impact of the pandemic on this educational sector in an Australian setting; specifically, we discuss how the Research School of Population Health at the Australian National University adjusted and adapted to the changing circumstances arising from the pandemic. In this respect, two adjustments (both described in detail in the text) in the way mental health education was delivered at the School were proposed to mitigate the impact of Covid-19 and enhance the university's capacity to provide quality public health education to students. Thus, this essay shows that it is possible to design educational interventions that surmount the challenges posed by the pandemic. In addition, educators may use the examples cited in this paper to guide them to respond appropriately to the challenges that have arisen in terms of health education due to Covid-19.

RESUMEN

BACKGROUND: University students experience high levels of mental health problems; however, very few seek professional help. Teaching staff within the university are well placed to assist students to seek support. AIMS: To investigate university teaching staff experiences of, and training needs around, assisting students with mental health problems. METHOD: A total of 224 teaching staff at the Australian National University completed an anonymous online survey (16.4% response rate from n ∼ 1370). Data on mental health training needs, and experiences of assisting students with mental health problems were described using tabulation. Qualitative data were analysed using thematic analysis. RESULTS: Most teaching staff (70.1-82.2%) reported at least moderate confidence in their ability to provide emotional support for students. However, many staff (60.0%) felt under-equipped overall to deal with student mental health problems; almost half (49.6%) reported they did not have access to formal training. Specific actions described in assisting students included referrals, offering support, or consulting others for advice. CONCLUSION: Given the high rates of students who approach staff about mental health problems, there is a critical need to provide and promote both formal mental health response training and explicit guidelines for staff on when, how, and where to refer students for help.

RESUMEN

Alzheimer's disease and dementia are common, highly disabling conditions frequently requiring residential care. This exploratory proof-of-concept study aimed to determine if the specialised Music Engagement Program (MEP) was sustainable, acceptable, and effective in improving quality of life, emotional wellbeing, and depression symptoms in this population. Sixteen residents, six staff members, and three family and community members took part in the evaluation of the MEP for people living with dementia in a residential aged-care nursing home in Canberra, Australia. Multiple methods were used. Quantitative evaluation assessed residents' depression symptoms (Cornell scale) at pre- and post-intervention, and emotional wellbeing pre- and post-session. Qualitative interviews with staff, and family and community members addressed the MEP's acceptability and potential sustainability. Results showed residents' mean depression scores were reduced from pre- to post-intervention (p = .039; dz = 0.72). Interviews established multiple benefits for residents including improved mood, calmness, and reduced aggression. However, staff did not believe it was feasible to continue the MEP sessions beyond the trial period without an external facilitator, citing potential difficulties in adhering to internal activities due to time constraints. This pilot study provides encouraging preliminary evidence for the MEP's acceptability and potential effectiveness for improving depression and wellbeing in this group.

RESUMEN

BACKGROUND: Of the millions of students enrolled in university, up to 50% will experience a mental disorder. Many of these students do not seek help, and for those who do, university-based services are often over-burdened. Anonymous, evidence-based, online interventions can improve students' access to mental health support. The Uni Virtual Clinic (UVC) is a transdiagnostic online mental health program designed specifically for university students. This paper reports on a randomised controlled trial examining the effectiveness of the UVC in a sample of Australian university students. METHODS: University students with elevated psychological distress (K10>15; n = 200) were randomised to the UVC intervention or a waitlist control condition for a period of 6 weeks. Baseline, post-intervention, and 3-month follow-up surveys assessed depression, anxiety, self-efficacy, quality of life, adherence, and satisfaction with the UVC intervention. RESULTS: Mixed models analysis demonstrated that use of the UVC was associated with small significant reductions in social anxiety and small improvements in academic self-efficacy. The program was not effective in reducing symptoms of depression, anxiety, or psychological distress compared to a control group. The majority of participants in the intervention condition who were retained at follow-up engaged with the program, and most of these participants reported satisfaction with the UVC. DISCUSSION: The results suggest that multi-component online interventions such as the UVC have utility in a university environment. Future trials of the UVC should examine the impact of guidance and/or tailoring on treatment efficacy, and the potential role of the UVC in a stepped care model incorporating on-campus services.

RESUMEN

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.
