  • The study aimed to analyze how sleep discrepancy has been understood in previous research and evaluate the methods used to measure it.
  • A thorough search across multiple databases in April 2022 identified 244 relevant studies, revealing significant variability in how sleep was measured both subjectively and objectively.
  • The findings highlight that sleep discrepancy is often viewed as a mismatch in sleep states or time, with several methodological challenges needing attention, including issues with measurement definitions and statistical analysis.

Objective: This study aimed to gather opinions and establish consensus among audiologists and patients on supporting individuals with mental health concerns in audiology settings.

Design: Utilising a modified electronic Delphi survey, a panel of 25 experts engaged in three rounds of data collection over 12 weeks. Participants provided open-text responses in Round 1 describing "clinical practices that can be employed to support to patients presenting with mental health concerns", and the research team combined these with relevant clinical practices from literature searches.

Background: Resilience refers to the process of demonstrating better outcomes than would be expected based on the adversity one experienced. Resilience is increasingly measured using a residual approach, which typically assesses adversity and mental health outcomes over a longitudinal timeframe. It remains unknown to what extent such a residual-based measurement of resilience is sensitive to variation in acute stress resilience, a candidate resilience factor.

This was the first study to use cluster analysis to characterise sleep discrepancy (the discordance between self-reported and objective sleep) across multiple sleep parameters, in community-dwelling older adults. For sleep efficiency, negative discrepancy (the tendency to self-report worse sleep than objectively-measured) was associated with poorer memory, independent of insomnia severity, depressive symptoms and objective sleep. This suggests a unique role for sleep discrepancy as a possible risk factor for future cognitive decline, and warrants the need for further research.

Introduction: Obstructive sleep apnoea (OSA) is a multisystem, debilitating, chronic disorder of breathing during sleep, resulting in a relatively consistent pattern of cognitive deficits. More recently, it has been argued that those cognitive deficits, especially in middle-aged patients, may be driven by cardiovascular and metabolic comorbidities, rather than by distinct OSA-processes, such as are for example ensuing nocturnal intermittent hypoxaemia, oxidative stress, neuroinflammation, and sleep fragmentation.

Methods: Thus, we undertook to define cognitive performance in a group of 27 middle-aged male patients with untreated OSA, who had no concomitant comorbidities, compared with seven matched controls (AHI mean ± S.

Objectives: The ask, inform, manage, encourage, refer (AIMER) program is a behavior change intervention designed to increase the frequency with which hearing healthcare clinicians (HHCs) ask about and provide information regarding mental wellbeing within adult audiology services. The objective of this study was to systematically evaluate the first iteration of the AIMER program to determine whether the intervention achieved the changes in HHC behaviors anticipated and to evaluate feasibility of implementing the AIMER program based on the implementation protocol.

Design: The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to guide this evaluation.

Background: Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often experience sleep difficulties such as difficulty initiating and maintaining sleep. Problem sleep may impact children's daily functioning and behaviors and exacerbate ADHD symptoms. Most effective behavioral interventions to improve sleep are conducted in person, limiting accessibility to treatment for individuals in remote or rural communities or those who are unable to attend a clinic.

Introduction: The short version of the Conners' Adult ADHD Rating Scales (CAARS-S:S) is a self-report measure used to identify symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) during adulthood. However, its psychometric properties specifically in emerging adults, or the transitional age group between adolescence and adulthood, remain understudied. This study aimed to validate the factor structure of the CAARS-S:S in a sample of emerging adults.

Study Objectives: There is currently no way to estimate the period of time a person has had obstructive sleep apnoea (OSA). Such information would allow identification of people who have had an extended exposure period and are therefore at greater risk of other medical disorders; and enable consideration of disease chronicity in the study of OSA pathogenesis/treatment.

Method: The 'age of OSA Onset' algorithm was developed in the Wisconsin Sleep Cohort (WSC), in participants who had ≥2 sleep studies and not using continuous positive airway pressure (n = 696).

Study Objectives: Despite the negative impact of poor sleep on mental health, evidence-based insomnia management guidelines have not been translated into routine mental healthcare. Here, we evaluate a state-wide knowledge translation effort to disseminate sleep and insomnia education to graduate psychology programs online using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) evaluation framework.

Methods: Using a non-randomized waitlist control design, graduate psychology students attended a validated 6-hour online sleep education workshop delivered live as part of their graduate psychology program in Victoria, Australia.

Introduction: Anomalous perceptions are characterised by the subjective experience of a range of distorted and/or hallucinatory percepts. Whilst considerable attention has been paid to the neurocognitive processes contributing to anomalous perceptions amongst older adults, less is known about the social factors (e.g.

Article Synopsis
  • The Sleep Psychology Workshop was created to teach trainee psychologists about the impact of sleep on mental health, addressing a gap in current psychology training.
  • After attending the workshop, trainees significantly improved their sleep knowledge and felt more confident in using sleep assessment tools, with 91% rating the workshop as "excellent."
  • Follow-up six months later showed that all trainees started regularly asking clients about sleep, and many reported their own sleep improved as well.

Objective: Brain reserve, cognitive reserve, and education are thought to protect against late-life cognitive decline, but these variables have not been directly compared to one another in the same model, using future cognitive and functional decline as outcomes. We sought to determine whether the influence of these protective factors on executive function (EF) and daily function decline was dependent upon Alzheimer's disease (AD) pathology severity, as measured by the total tau to beta-amyloid (T-τ/Aβ) ratio in cerebrospinal fluid (CSF).

Method: Participants were 1201 older adult volunteers in the Alzheimer's Disease Neuroimaging Initiative (ADNI) study.

Background: The residual approach to measuring cognitive reserve (using the residual reserve index) aims to capture cognitive resilience conferred by cognitive reserve, but may be confounded by factors representing brain resilience. We sought to distinguish between brain and cognitive resilience by comparing interactions between the residual reserve index and amyloid, tau, and neurodegeneration ["AT(N)"] biomarkers when predicting executive function. We hypothesized that the residual reserve index would moderate at least one path from an AT(N) biomarker to executive function (consistent with cognitive resilience), as opposed to moderating a path between two AT(N) biomarkers (suggestive of brain resilience).
