- Description: Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial or complete cessation of breathing during sleep and increased effort to breathe. This study examined patients who underwent overnight polysomnographic studies in a major sleep laboratory in Saudi Arabia. The study aimed to determine the extent to which intermittent hypoxia, sleep disruption, and depressive symptoms are independently associated with cognitive impairments in OSA. In the sample of 90 participants, 14 had no OSA, 30 mild OSA, 23 moderate OSA, and 23 severe OSA. The findings revealed that hypoxia and sleep fragmentation are independently associated with impairments of sustained attention and reaction time (RT). Sleep fragmentation, but not hypoxia, was independently associated with impairments in visuospatial deficits. Depressive symptoms were independently associated with impairments in the domains of sustained attention, RT, visuospatial ability, and semantic and episodic autobiographical memories. Since the depressive symptoms are independent of hypoxia and sleep fragmentation, effective reversal of cognitive impairment in OSA may require treatment interventions that target each of these factors. © Sleep Research Society 2020.

- Description: Asylum seekers are susceptible to chronic non-communicable diseases pre- and post-arrival due to poor living conditions, unhealthy lifestyles and restrictive and poor access to health services. Despite their need for constant and continuous health care access due to poor health, they face healthcare services access restrictions dependent on their visa conditions in Australia. Some visas only allow access to hospital services with restrictions on primary health services access such as GPs and free or discounted pharmaceutical products. In comparison, disadvantaged host populations have access to free/discounted pharmaceutical products and unrestricted access to primary and secondary health care. Ten professionals who constantly engage with asylum seekers in three large asylum seeker centres in Melbourne were interviewed either face-to-face or over the phone. The interviews were essential to understand how health inequities may be addressed for asylum seekers. Interviews were audio-recorded, transcribed verbatim and analysed using a thematic analysis framework. Their recommendations, based mainly on their experience and evaluation of programs, were: (1) cultural competence training (2) use of interpreters (3) free access to health services and medications (4) use of English learning to promote health literacy and community integration (5) robust chronic non-communicable diseases screening and (6) health promotion and accessible food programs. © 2021 La Trobe University.

- Description: Paramedics face many challenges while on duty, one of which is working different types of shifts. Shift work has been linked to a number of health issues such as insomnia, depression, and anxiety. Besides shift work, Saudi paramedics, a group that has not been investigated for sleep or mental health issues previously, may be facing more demands than Australian paramedics due to lower numbers of paramedics in comparison to the general population. The aim of this study was to investigate the prevalence of sleep and mental health disorders among paramedics in Saudi Arabia and Australia. Paramedics were invited to complete a survey to assess stress, post-traumatic stress disorder (PTSD), depression, anxiety, daytime sleepiness, insomnia, sleep quality, shift work disorder, obstructive sleep apnoea, fatigue, and general health. A total of 104 males Saudi paramedics (M age = 32.5 +/- 6.1 years) and 83 males paramedics from Australia (M age = 44.1 +/- 12.1 years) responded to the survey. Significantly higher rates of depression, PTSD, insomnia, and fatigue, along with significantly poorer physical functioning were observed among Saudi paramedics in comparison with Australian paramedics. However, Australian paramedics reported significantly poorer sleep quality and general health in comparison to Saudi paramedics. After removing the effect of driving and working durations, outcomes were no longer significant. The higher burden of depression and PTSD among Saudi paramedics may be explained by longer hours spent driving and longer work durations reported by this group. Taking into consideration the outcomes reported in this study, more investigations are needed to study their possible effects on paramedics' cognition, performance, and safety.

- Description: Objectives: Two experimental studies were conducted to test and compare whether different pre-performance routines (i.e., left-hand dynamic handgrip and an extensive routine) can improve (and potentially have a combined effect on) accuracy in closed, self-paced motor tasks. Design/method: Study 1 used a standardised laboratory task to measure motor performance, while Study 2 was a field experiment measuring tenpin bowling accuracy and in-game performance as outcome variables. Both studies consisted of a pretest phase followed by one or two test phases using a group-specific pre-performance routine (PPR), or control, condition. Results: Results of both studies indicated that the inexperienced students (Study 1) and experienced athletes (Study 2) within the intervention groups were more accurate when using the intervention than a control group (not provided an intervention). Using a combined (i.e., left-hand dynamic handgrip and extensive) PPR may not have additive performance effects. Furthermore, using a PPR intervention did not equate to better in-game performance in Study 2. Conclusions: These studies indicate that the element of left-hand dynamic handgrip as a PPR may be comparable to control groups, but further research is needed to determine if it is comparable to extensive PPR interventions that promote concentration on the task for increased performance generally (and under pressure).

- Description: This study tested the hypothesis that adverse events are associated with increased risk of onset of anxiety disorders. Data from Waves 1 (N = 43,093; 2001–2002) and 2 (N = 34,653; 2004–2005) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) were used to assess whether adverse events at baseline are associated with increased risk of anxiety disorder onset over three years of follow up. Sixty-six percent (SE: 1.0) of respondents with an anxiety disorder in the intervening period between Waves 1 and 2 had experienced an adverse life event in the year prior to the Wave 1 interview. In logistic regression models adjusted for sociodemographic and psychiatric characteristics, adverse life events at baseline were associated with anxiety disorder onset within the three-year follow up period. The pattern of association between adverse events and anxiety disorder onset was similar across sub-types, and injury, illness or death of family or close friends consistently had the strongest association with anxiety disorder onset. These findings suggest that adverse life events play a role in the onset of anxiety disorders.

- Description: Background: Electronic methods are increasingly being used to manage health-related data among sporting populations. Collection of such data permits the analysis of injury and illness trends, improves early detection of injuries and illnesses, collectively referred to as health problems, and provides evidence to inform prevention strategies. The Athlete Management System (AMS) has been employed across a range of sports to monitor health. Australian combat athletes train across the country without dedicated national medical or sports science teams to monitor and advocate for their health. Employing a Web-based system, such as the AMS, May provide an avenue to increase the visibility of health problems experienced by combat athletes and deliver key information to stakeholders detailing where prevention programs May be targeted. Objective: The objectives of this paper are to (1) report on the feasibility of utilizing the AMS to collect longitudinal injury and illness data of combat sports athletes and (2) describe the type, location, severity, and recurrence of injuries and illnesses that the cohort of athletes experience across a 12-week period. Methods: We invited 26 elite and developing athletes from 4 Olympic combat sports (boxing, judo, taekwondo, and wrestling) to participate in this study. Engagement with the AMS was measured, and collected health problems (injuries or illnesses) were coded using the Orchard Sports Injury Classification System (version 10.1) and International Classification of Primary Care (version 2). Results: Despite >160 contacts, athlete engagement with online tools was poor, with only 13% compliance across the 12-week period. No taekwondo or wrestling athletes were compliant. Despite low overall engagement, a large number of injuries or illness were recorded across 11 athletes who entered data—22 unique injuries, 8 unique illnesses, 30 recurrent injuries, and 2 recurrent illnesses. The most frequent injuries were to the knee in boxing (n=41) and thigh in judo (n=9). In this cohort, judo players experienced more severe, but less frequent, injuries than boxers, yet judo players sustained more illnesses than boxers. In 97.0% (126/130) of cases, athletes in this cohort continued to train irrespective of their health problems. Conclusions: Among athletes who reported injuries, many reported multiple conditions, indicating a need for health monitoring in Australian combat sports. A number of factors May have influenced engagement with the AMS, including access to the internet, the design of the system, coach views on the system, previous experiences with the system, and the existing culture within Australian combat sports. To increase engagement, there May be a requirement for sports staff to provide relevant feedback on data entered into the system. Until the Barriers are addressed, it is not feasible to implement the system in its current form across a larger cohort of combat athletes.

- Description: Introduction: “Body swapping” illusions have been used to explore factors contributing to the experience of “owning” an artificial body. Preliminary research indicated that those people diagnosed with schizophrenia experience more vivid illusions of this kind than do “normal” individuals. Objectives: Here, we explored whether participants who rated themselves “high” on the cognitive-perceptual factor of the Schizotypal Personality Questionnaire (SPQ) experienced a more compelling sense of immersion in a variation of the body swapping illusion: The Barbie Doll Illusion. We also hypothesised that these individuals would experience a change in size perception when immersed in the illusion. Method: Forty-four participants wore a pair of Head-Mounted Display goggles connected to a video-camera, and thus a doll’s body replaced their own body in their visual field. In two conditions, touch was either applied synchronously or asynchronously to the doll’s and each participant’s leg. After each condition, participants filled out a questionnaire relating to their experience in the illusion. When both conditions were completed, they filled out the SPQ. Results: Our first hypothesis was confirmed, which suggested that people with higher cognitive-perceptual SPQ scores do indeed experience a more compelling Barbie Doll Illusion; however, our second hypothesis was not supported. Conclusion: Our study demonstrated, for the first time, that proneness to the positive and interpersonal factors of schizotypy in a normal population is sufficient to produce a compelling sense of swapping bodies.

- Description: The Internet Gaming Disorder Scale Short-Form (IGDS9-SF) has been extensively used worldwide to assess Internet Gaming Disorder (IGD) behaviors. Therefore, investigating cultural limitations and implications in its applicability is necessary. The cross-cultural feasibility of a test can be psychometrically evaluated with measurement invariance analyses. Thus, the present study used Multigroup Confirmatory Factor Analysis (MGCFA) to examine the IGDS9-SF measurement invariance across garners from the United States of America (USA), India, and the United Kingdom (UK). A total of 1013 garners from the USA (n = 405), India (n = 336), and the UK (n = 272) were recruited. Although the one-factor structure of the IGD construct was supported, cross-country variations were demonstrated considering the way that this was reflected on items assessing preoccupation/salience, tolerance, deception, gaming escapism/mood modification, as well as daily activities' impairment related to gaming. Furthermore, the same scores on items assessing withdrawal symptoms, tolerance, lack of control over gaming engagement, escapism/mood modification and daily activities impairment associated to gaming, have been found to reflect various levels of IGD severity across the three groups. The implications of these results are further discussed in the context of existing evidence regarding the assessment of IGD.

- Description: Purpose: Point duration in competitive tennis is becoming shorter, highlighting a greater emphasis on performance of the first strokes of each point, in particular, the performance of the server. Methods: Descriptive measures of the video-based analysis included stroke type, point outcome and stroke position of the first two strokes of the server (service and first shot) during 10 randomly selected sets of competition on hard court. All participants (male; n=8) were of the age group 14 years and below and competed in national level events. Results: The performance of the first serve is characterized by an “in-percentage” of 54.6% and an improved chance of winning the point (for the server) following a first serve (55.9%; P<0.001) compared to a second serve (42.9%). The majority of stroke positions for first-shot winners were located in the central zone of the court (52.1%; P<0.01). In comparison to the error rate of all examined strokes, we observed an increased error rate of the first shot (16.5% vs. 22.4%; P<0.01). Conclusion: Contrasting to professionals, juniors produce more first-serve errors and win fewer points directly via the serve. Success in junior tennis relies in minimizing errors within short rallies specifically on the first shot of the server. Coaches of national level junior tennis players should focus on strategies to optimize court position following the serve and service percentage to increase competitive success rate. To achieve this, the server should utilize the serve as a “set-up” tool, dictating the direction of the returner’s return of serve within the central zones of the court. © The Author(s) 2017.

- Description: Chronic ill health has recently emerged as the most important health issue on a global scale. Rural communities are disproportionally affected by chronic ill health. Many health systems are centred on the management of acute conditions and are often poorly equipped to deal with chronic ill health. Cardiovascular disease (CVD) is one of the most prominent chronic ill health conditions and the principal cause of mortality worldwide. In this paper, CVD is used as an example to demonstrate the disparity between rural and urban experience of chronic ill health, access to medical care and clinical outcomes. Advances have been made to address chronic ill health through improving self-management strategies, health literacy and access to medical services. However, given the higher incidence of chronic health conditions and poorer clinical outcomes in rural communities, it is imperative that integrated health care emphasises greater collaboration between services. It is also vital that rural GPs are better supported to work with their patients, and that they use consumer-directed approaches to empower patients to direct and coordinate their own care. © La Trobe University 2016.

- Description: The evolution of venous access via peripheral cannulation, particularly in relation to the risks and the benefits of this procedure, is reported widely in the literature. However, there is limited research specific to the patient experience of undergoing venous access. The intent of this qualitative study was to understand patients' experience of venous access, with the aim of bringing forth their voices about the experiences of repeated venous access/cannulation attempts. This qualitative study used a hermeneutic phenomenological approach to explore the experiences of 15 participants in two rural oncology units in Australia. The participants had experienced repeated peripheral cannulation in order to receive chemotherapy. Study participants were asked to describe what it was like for them to be repeatedly cannulated. Data were collected via audiotaped individual interviews, the participants' stories were transcribed and analysed thematically. Themes emerged from the participants' stories that provided insights into their perceptions of the experience of being cannulated and the decision-making processes regarding how and where the procedure occurred. The findings suggest that a holistic approach to care was often missing causing the participants to feel vulnerable. Gaining insight into their experiences led to a greater understanding of the impact of this procedure on patients and the need to improve care through encouraging more collaborative decision-making processes between clinicians and patients. The implications for policy and practice focus on improving patient outcomes via procedural governance and education, with the intent of translating the findings from this research into evidence-based practice.

- Description: Objective: Children with Developmental Coordination Disorder demonstrate a lack of automaticity in handwriting as measured by pauses during writing. Deficits in visual perception have been proposed in the literature as underlying mechanisms of handwriting difficulties in children with DCD. The aim of this study was to examine whether correlations exist between measures of visual perception and visual motor integration with measures of the handwriting product and process in children with DCD. Method: The performance of twenty-eight 8-14 year-old children who met the DSM-5 criteria for DCD was compared with 28 typically developing (TD) age and gender-matched controls. The children completed the Developmental Test of Visual Motor Integration (VMI) and the Test of Visual Perceptual Skills (TVPS). Group comparisons were made, correlations were conducted between the visual perceptual measures and handwriting measures and the sensitivity and specificity examined. Results: The DCD group performed below the TD group on the VMI and TVPS. There were no significant correlations between the VMI or TVPS and any of the handwriting measures in the DCD group. In addition, both tests demonstrated low sensitivity. Conclusion: Clinicians should execute caution in using visual perceptual measures to inform them about handwriting skill in children with DCD. © 2016 The Authors.

- Description: This review explores the differences between agility in invasion sports (defined as including reactive decision-making) and change-of-direction speed (CODS), and highlights the implications for training. Correlations between agility tests and CODS tests indicate that they represent independent skills. Agility tests discriminate higher-from lower-standard athletes better than CODS tests, indicating that the cognitive element of agility is important to performance. Training studies have shown that the development of strength qualities can transfer to gains in CODS, but this has never been shown for agility. There is some evidence that the importance of physical qualities is greater for CODS than for agility. It was concluded that the reactive element should be included in agility training, testing and research. While there appears to be no research evidence for the benefits of strength and power training, there is some support for the use of small-sided games for improving agility.

- Description: Objectives: Researchers have identified that pre-performance routines improve performance under pressure, yet have not investigated the effects of post-performance routines. Thus, the purpose of the current study was to examine whether the type of performance routine training could improve tenpin bowling accuracy and in-game performance. Design: A mixed-method design was adopted, whereby the impact of a performance routine intervention on performance accuracy and in-game performance was examined. This was followed by participants completing semi-structured interviews which explored the perceived effect of those routines. Method: Thirty-six experienced tenpin bowlers completed 30 accuracy shots pre- and post-intervention training, with league scores obtained for in-game performance comparison. Four groups (i.e., pre-performance routine [PPR], post-performance routine [POST], combined pre-post routine, and a control group) practiced 12 games across four weeks while listening to the group specific routine instruction on an IPod. Results: It was noted that accuracy improved (albeit non-significantly) for the PPR and combined pre-post routine group, but not the other groups. Critically, all intervention groups (PPR, POST & COMBO) improved in-game performance. The qualitative data indicated that both the PPR and POST was perceived to influence positively performance, attentional and emotional control, self-awareness, self-confidence, motivation. The PPR was also considered to enhance a state of readiness, and perceived control. Conclusions: Results indicate that the PPR training enhanced accuracy and in-game performance, with the POST training acting as a supportive role for in-game performance as evidenced by the qualitative and quantitative data. Future research should continue to investigate the effects of POSTs. (C) 2015 Elsevier Ltd. All rights reserved.

- Description: Background: Internet-based assessment has the potential to assist with the diagnosis of mental health disorders and overcome the barriers associated with traditional services (eg, cost, stigma, distance). Further to existing online screening programs available, there is an opportunity to deliver more comprehensive and accurate diagnostic tools to supplement the assessment and treatment of mental health disorders. Objective: The aim was to evaluate the diagnostic criterion validity and test-retest reliability of the electronic Psychological Assessment System (e-PASS), an online, self-report, multidisorder, clinical assessment and referral system. Methods: Participants were 616 adults residing in Australia, recruited online, and representing prospective e-PASS users. Following e-PASS completion, 158 participants underwent a telephone-administered structured clinical interview and 39 participants repeated the e-PASS within 25 days of initial completion. Results: With structured clinical interview results serving as the gold standard, diagnostic agreement with the e-PASS varied considerably from fair (eg, generalized anxiety disorder:kappa=.37) to strong (eg, panic disorder:kappa=.62). Although the e-PASS' sensitivity also varied (0.43-0.86) the specificity was generally high (0.68-1.00). The e-PASS sensitivity generally improved when reducing the e-PASS threshold to a subclinical result. Test-retest reliability ranged from moderate (eg, specific phobia:kappa=.54) to substantial (eg, bulimia nervosa:kappa=.87). Conclusions: The e-PASS produces reliable diagnostic results and performs generally well in excluding mental disorders, although at the expense of sensitivity. For screening purposes, the e-PASS subclinical result generally appears better than a clinical result as a diagnostic indicator. Further development and evaluation is needed to support the use of online diagnostic assessment programs for mental disorders.

- Description: Background Adjunctive psychosocial interventions are efficacious in bipolar disorder, but their incorporation into routine management plans are often confounded by cost and access constraints. We report here a comparative evaluation of two online programs hosted on a single website (www.moodswings.net.au). A basic version, called MoodSwings (MS), contains psychoeducation material and asynchronous discussion boards; and a more interactive program, MoodSwings Plus (MS-Plus), combined the basic psychoeducation material and discussion boards with elements of Cognitive Behavioral Therapy. These programs were evaluated in a head-to-head study design. Method Participants with Bipolar I or II disorder (n=156) were randomized to receive either MoodSwings or MoodSwings-Plus. Outcomes included mood symptoms, the occurrence of relapse, functionality, Locus of Control, social support, quality of life and medication adherence. Results Participants in both groups showed baseline to endpoint reductions in mood symptoms and improvements in functionality, quality of life and medication adherence. The MoodSwings-Plus group showed a greater number of within-group changes on symptoms and functioning in depression and mania, quality of life and social support, across both poles of the illness. MoodSwings-Plus was superior to MoodSwings in improvement on symptoms of mania scores at 12 months (p=0.02) but not on the incidence of recurrence. Limitations The study did not have an attention control group and therefore could not demonstrate efficacy of the two active arms. There was notable (81%) attrition by 12 months from baseline. Conclusion This study suggests that both CBT and psychoeducation delivered online may have utility in the management of bipolar disorder. They are feasible, readily accepted, and associated with improvement. © 2014 Elsevier B.V. All rights reserved.

- Description: The main purpose of this study was to determine the association between leg power and sprint technique with 20-m sprint performance. Seventy-seven elite junior Australian Rules football players were assessed on a 20-m sprint test, a countermovement jump (CMJ) and a two bound test, and on a new method of quantifying sprint technique from simple video recordings. Technique assessment involved rating 14 points on a scale from 1-5. Players were median-split into faster and slower groups based on their 20-m times, and they were compared for differences in leg power and technique. The faster group was significantly better (p<0.05) in the two-bound test (5.2%) and the technique score (8.2%), but not in the CMJ (p>0.05). A multiple regression indicated that the two-bound test and technique accounted for 37.7% of the variance associated with the 20-m sprint time (p<0.05). It was concluded that the technique assessment tool captured some important characteristics of 20-m sprint performance and could potentially be used to profile or monitor athletes. Further the two-bound test is a more relevant test for developing athletes because of its specificity to sprinting, compared to the CMJ.

- Description: BACKGROUND: A relative newcomer to the field of psychology, e-mental health has been gaining momentum and has been given considerable research attention. Although several aspects of e-mental health have been studied, 1 aspect has yet to receive attention: the structure of comorbidity of psychological disorders and their relationships with measures of psychosocial adjustment including suicidal ideation in online samples. OBJECTIVE: This exploratory study attempted to identify the structure of comorbidity of 21 psychological disorders assessed by an automated online electronic psychological assessment screening system (e-PASS). The resulting comorbidity factor scores were then used to assess the association between comorbidity factor scores and measures of psychosocial adjustments (ie, psychological distress, suicidal ideation, adequate social support, self-confidence in dealing with mental health issues, and quality of life). METHODS: A total of 13,414 participants were assessed using a complex online algorithm that resulted in primary and secondary Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) diagnoses for 21 psychological disorders on dimensional severity scales. The scores on these severity scales were used in a principal component analysis (PCA) and the resulting comorbidity factor scores were related to 4 measures of psychosocial adjustments. RESULTS: A PCA based on 17 of the 21 psychological disorders resulted in a 4-factor model of comorbidity: anxiety-depression consisting of all anxiety disorders, major depressive episode (MDE), and insomnia; substance abuse consisting of alcohol and drug abuse and dependency; body image-eating consisting of eating disorders, body dysmorphic disorder, and obsessive-compulsive disorders; depression-sleep problems consisting of MDE, insomnia, and hypersomnia. All comorbidity factor scores were significantly associated with psychosocial measures of adjustment (P<.001). They were positively related to psychological distress and suicidal ideation, but negatively related to adequate social support, self-confidence, and quality of life. CONCLUSIONS: This exploratory study identified 4 comorbidity factors in the e-PASS data and these factor scores significantly predicted 5 psychosocial adjustment measures.

- Description: Marriage has been identified as a protective factor in relation to suicide among older adults. The current study aimed to investigate whether sense of belonging mediated the marital status-suicidal ideation relationship, and whether gender moderated the mediation model. It was hypothesized that the relationship between being widowed and lower levels of sense of belonging, and between lower levels of belonging and higher levels of suicidal ideation, would be stronger for older men than older women. A community sample of Australian men (n = 286) and women (n = 383) aged from 65 to 98 years completed the psychological subscale of the Sense of Belonging Instrument and the suicide subscale of the General Health Questionnaire. The results supported the moderated mediation model, with gender influencing the marital status-sense of belonging relation. For men, widowhood was associated with lower levels of belongingness, whereas for women, marital status was unrelated to sense of belonging. It would appear crucial to develop and implement interventions which assist older men to find new ways to feel important and valued after the death of their spouse.
