There has been significant disruption to the lives and mental health of adolescents during the COVID-19 pandemic. The purpose of this study was to assess the psychological and lifestyle impact of the pandemic on Australian adolescents, using an online survey, administered during the outbreak. Self-report surveys were administered online to a sample of 760 Australian adolescents aged 12–18 years assessing impact on a range of domains including behaviour, education, relationships, lifestyle factors (exercise, technology use, and sleep), and mental health outcomes (psychological distress, loneliness, health anxiety and well-being). Results showed that three quarters of the sample experienced a worsening in mental health, since the pandemic began, with negative impacts reported on learning, friendships and family relationships. There were also high higher levels of sleep disturbance, psychological distress and health anxiety, relative to normative samples. Effects on mental health were worse among those who reported a previous diagnosis of depression and/or anxiety relative to those without no such history. Adolescents are already vulnerable to the onset of mental illness at this developmental stage, and the current research underscores the need to find rapid and accessible ways to support adolescent mental health during times of crisis.

E-mental health programmes have great potential to provide young people with access to mental health support. However, it is commonly reported that adherence to these programmes is low. Low adherence can be problematic, particularly if young people do not receive the full benefits of a programme. In a research trial setting, non-adherence to treatment recommendations can prevent researchers from drawing strong conclusions about effectiveness. Although adherence has been recognised as an issue in need of attention, many of the reviews available are focused on adults and lack clear direction towards what strategies to employ. This paper presents a broad review of the adherence literature, focusing on factors associated with improving adherence to e-mental health among youth. Our view on the key elements to improve adherence identified from the existing literature are presented, and key recommendations for e-mental health intervention design are provided. These include: developing and communicating adherence guidelines based on individuals’ needs and symptom severity, including customisable features to provide a tailored experience and promote a sense of agency, including engagement checks and adopting a user-centred approach by utilising strategies such as co-design. This paper provides guidance to intervention designers and researchers by outlining recommendations and considerations for intervention development and research design.

A series of experiments studied the effects of the interval between extinction trials on the loss of context conditioned freezing responses. Rats were shocked in one context (A) but not in another (B) and subjected to extinction trials in context A. In Experiment 1, massed trials produced more rapid loss than spaced trials. A shift from spaced to massed trials maintained this loss, but the shift from massed to spaced trials restored lost responses. Experiments 2-5 examined this effect of massed trials on responding across spaced trials. They provided evidence that (a) a single trial was as effective as multiple daily massed trials, (b) learning occurred on the first of the massed trials but not on later ones, and (c) the first trial reduced the amount learned across subsequent massed trials. Finally, alternating extinction trials in A and B produced more response loss across spaced trials than blocks of trials in A and B. The results were discussed in terms of the role accorded to self-generated priming in the models developed by A. R. Wagner (1978, 1981).

The programmed cell death 1 (PD-1) pathway represents a major immune checkpoint, which may be engaged by cells in the tumor microenvironment to overcome active T-cell immune surveillance. Pembrolizumab (Keytruda ® , MK-3475) is a potent and highly selective humanized monoclonal antibody of the IgG4/kappa isotype designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2. This blockade enhances the functional activity of T-cells to facilitate tumor regression and ultimately immune rejection.

Background Since the COVID-19 outbreak, few studies have investigated the positive psychological consequences on young people. This study examined resilience, positive experiences, and coping strategies reported by Australian adolescents during COVID-19. Methods Self-report surveys were administered online to a sample of 760 Australian adolescents aged 12–18 years. Quantitative and qualitative methods were used to assess resilience, positive experiences, and coping strategies. Exploratory regression analyses were conducted to explore the relationship between resilience and demographics and mental illness history, as well as between resilience and positive experiences. Results Overall, adolescents were somewhat resilient (M = 20.93, SD = 8.29). They reported positive experiences during COVID-19, including increased empathy, compassion, gratitude, and connection with others, and reported using a range of active coping strategies. Having a mental illness history and identification as female or non-binary gender were associated with lower resilience (Bs > 2.82, ps < 0.001). Further, resilience was associated with decreased psychological distress (OR = 0.89, p < 0.001) and with increased positive experiences (ORs > 1.03, ps < 0.001). Conclusions Our results indicate that Australian adolescents commonly reported positive experiences and used active coping strategies during COVID-19. Some young people demonstrated higher levels of resilience and were able to make the most out of an unpredictable situation that severely disrupted their daily routine. However, further prospective research using longitudinal methods is necessary to examine causal relationships between variables. An implication of our findings is that resilience-building programs for adolescents may be effective in increasing adaptability after adversity (e.g., climate change, bushfires, pandemics).
