ABSTRACT

Historically, the analysis of stimulus-dependent time-frequency patterns has been the cornerstone of most electroencephalography (EEG) studies. The abnormal oscillations in high-frequency waves associated with psychotic disorders during sensory and cognitive tasks have been studied many times. However, any significant dissimilarity in the resting-state low-frequency bands is yet to be established. Spectral analysis of the alpha and delta band waves shows the effectiveness of stimulus-independent EEG in identifying the abnormal activity patterns of pathological brains. A generalized model incorporating multiple frequency bands should be more efficient in associating potential EEG biomarkers with first-episode psychosis (FEP), leading to an accurate diagnosis. We explore multiple machine-learning methods, including random-forest, support vector machine, and Gaussian process classifier (GPC), to demonstrate the practicality of resting-state power spectral density (PSD) to distinguish patients of FEP from healthy controls. A comprehensive discussion of our preprocessing methods for PSD analysis and a detailed comparison of different models are included in this paper. The GPC model outperforms the other models with a specificity of 95.78% to show that PSD can be used as an effective feature extraction technique for analyzing and classifying resting-state EEG signals of psychiatric disorders.

ABSTRACT

Children and adolescents diagnosed with an eating disorder often meet the diagnosis of another mental health disorder. In addition to eating disorders, individuals with comorbid disorders have higher suicide rates and more severe and chronic eating disorder symptoms. The present research aimed to investigate the influence of comorbid conditions on the treatment outcomes of children and adolescents that attended a public community mental health service. It was hypothesised that the patients with comorbidities would have a more extended treatment duration, slower rates of weight restoration, more hospital admissions for medical compromise, and poorer functioning than those without comorbidities. Data from 78 past patients at the Eating Disorder Program in Queensland, Australia, were analysed. Patients with comorbidities demonstrated similar recovery rates to those without comorbidities. However, those with comorbid conditions had longer episodes of treatment. The study's results support using Family Based Treatment for patients with and without comorbidities. The implications of the findings for public mental health services and directions for future research are discussed.

ABSTRACT

Day programs have received significant consideration within psychological literature as part of a continuum of mental health services. With increasing attention on the prevalence of eating disorders in children and adolescents, and the need for early intervention to minimize the costs and burden of the disorder, eating disorder day programs (also referred as partial hospitalization) have begun to emerge around the world. Despite their widespread use, no reviews to date have examined the efficacy of day programs for the treatment of eating disorders in children and adolescents. The current narrative literature review aims to describe and evaluate the efficacy of day programs for children and adolescents. The literature review was conducted according to the PRISMA guidelines and aimed to explore the outcomes and common program elements of day programs to guide clinical practice and service development. The review found variations amongst the day programs related to program elements, measures utilized and outcomes. Overall, the results suggest that day programs for children and adolescents are effective at restoring body weight, reducing eating disorder symptoms and addressing comorbid mental health concerns.

ABSTRACT

There is an increasing population of youths that report mental health issues. Research has shown that youths are reluctant to seek help for various reasons. A majority of those who do seek help are using digital mental health supports. Subsequently, efforts to promote youth mental health have focused on the use of digital applications as a means of overcoming barriers related to factors including stigma and lack of available services. The worldwide move toward recovery-oriented care led to emerging research on personal recovery amongst youths with mental health concerns. This study sought to address the need for recovery-oriented digital resources for youths. It utilised a qualitative design methodology to develop a rich interpretation of how youths are using digital interventions to support their mental health recovery journey. It sought to understand how existing digital applications are useful for youth recovery and identified characteristics associated with recovery and engagement. The content analysis generated five categories that represent facilitators of youth recovery and the thematic analysis identified key elements of digital applications that support youth recovery. The results offer complimentary support and guidance for recovery-oriented care and the use of digital mental health interventions in the promotion of personal recovery amongst youths.

ABSTRACT

Personal recovery represents a paradigm shift in how individuals are seen to benefit from mental health interventions, from a narrow view of symptom reduction to a holistic, multi-dimensional view of well-being, functional gains and rehabilitation. Although there is a large body of evidence supporting the use of recovery-oriented care in adults, research on personal recovery amongst youth with mental health concerns is an emerging area of research. Efforts to promote youth mental health have also focussed on the use of digital applications and platforms as a means of overcoming barriers related to factors including stigma and lack of available services. This systematic review aims to review the literature on existing internet-based, youth mental health interventions with regard to (a) identifying elements of the programs that align with the personal recovery and (b) outcome measures utilised in assessing personal recovery. Eleven papers were identified that met the inclusion criteria. Five of the programs reviewed from these eleven papers showed efficacy for recovery processes. The results offer preliminary support and guidance for the use of internet-based mental health interventions in the promotion of personal recovery amongst youth. Future research and practice are suggested to further develop understanding in this area.

ABSTRACT

AIM: To provide insight into the characteristics and treatment outcomes of children and adolescents accessing outpatient Child and Youth Mental Health Services (CYMHS), and to explore whether outcomes differ by age, sex, and ancestry background. This information can guide how to optimize the treatment delivered at these services. METHODS: An observational retrospective study was performed based on data from 3098 children and adolescents between age 5 and 18 who received treatment at Brisbane, Australia, community CYMHS between 2013-2018. Patient characteristics, service use, and clinician and parent rated Routine Outcome Measures (ROM) were extracted from electronic health records. RESULTS: Anxiety and mood disorders were the most common mental disorders (37% and 19%). In 1315 children and adolescents (42%), two or more disorders were diagnosed, and the far majority (88%) had experienced at least one psychosocial stressor. The ROM scores improved between start and end of treatment with Cohen's d effect sizes of around 0.9. However, ~50% of the children still scored in the clinical range at the end of treatment. Outcomes did not differ over gender and Indigenous status. CONCLUSIONS: Children and adolescents accessing CYMHS have severe and complex mental disorders as reflected by high rates of comorbidity, exposure to adverse circumstances and high symptom scores at the start of treatment. Despite the clinically relevant and substantial improvement, end ROM scores indicated the presence of residual symptoms. As this increases the risk for relapse, services should explore ways to improve treatment to further reduce mental health symptoms.

ABSTRACT

Difficulties in regulating feelings of shame is a risk factor for the onset and recurrence of mental health disorders. The present research investigated the impact of the individual differences in propensity to experience shame (or shame-proneness) on two emotion regulation strategies-perspective taking and positive reappraisal. A total of 228 participants, undergraduate students, were allocated randomly to one of the eight experimental conditions. The results revealed that for high shame-prone participants, the use of perspective taking, without positive reappraisal, led to a heightened experience of shame. In contrast, the combination of perspective taking and positive reappraisal led to reductions in shame among high shame-prone participants. The findings highlight the relationship between individual differences, and the separate and combined effects of affect regulation strategies on the experience of shame.
