Duty hours and incidents in flight among commercial airline pilots.

INTRODUCTION: Working long duty hours has often been associated with increased risk of incidents and accidents in transport industries. Despite this, information regarding the intermediate relationship between duty hours and incident risk is limited. This study aimed to test a work hours/incident model to identify the interplay of factors contributing to incidents within the aviation industry. METHODS: Nine hundred and fifty-four European-registered commercial airline pilots completed a 30-item survey investigating self-report attitudes and experiences of fatigue. Path analysis was used to test the proposed model. RESULTS: The fit indices indicated this to be a good fit model (χ(2) = 11.066, df = 5, p = 0.05; Comparative Fit Index = 0.991; Normed Fit Index = 0.984; Tucker-Lewis Index = 0.962; Root Mean Square of Approximation = 0.036). Highly significant relationships were identified between duty hours and sleep disturbance (r = 0.18, p < 0.001), sleep disturbance and fatigue in the cockpit (r = 0.40, p < 0.001), and fatigue in the cockpit and microsleeps in the cockpit (r = 0.43, p < 0.001). DISCUSSION: A critical pathway from duty hours through to self-reported incidents in flight was identified. Further investigation employing both objective and subjective measures of sleep and fatigue is needed.

The Design and Implementation of a Novel Mental Health Literacy Educational Intervention Program in Gaelic Footballers.

CONTEXT: Lack of education, stigma, and negative self-attitudes are key barriers to help-seeking in Gaelic footballers. With the prevalence of mental health issues in Gaelic footballers and the increased risk of experiencing mental health challenges after injury, mental health literacy (MHL) interventions are necessary. OBJECTIVES: To design and implement a novel MHL educational intervention program in Gaelic footballers. DESIGN: Controlled laboratory study. SETTING: Online. PATIENTS OR OTHER PARTICIPANTS: Elite and subelite Gaelic footballers divided into intervention (n = 70; age = 25.1 ± 4.5 years) and control (n = 75; age = 24.4 ± 6.0 years) groups. In the intervention group, 85 participants were recruited, but 15 dropped out after completing baseline measures. INTERVENTIONS: A novel educational intervention program, "GAA [Gaelic Athletic Association] and Mental Health-Injury and a Healthy Mind," was designed to address the key components of MHL and was underpinned by the Theory of Planned Behavior and the Help-Seeking Model. The intervention was implemented online via a brief 25-minute presentation. MAIN OUTCOME MEASURES: Measures of stigma, help-seeking attitudes, and MHL were completed by the intervention group at baseline, immediately after viewing the MHL program, and at 1 week and 1 month after the intervention. The control group completed the measures at similar time points. RESULTS: Stigma decreased, and attitudes toward help-seeking and MHL increased in the intervention group from baseline to after the intervention (P < .05), with significant differences sustained at 1-week and 1-month follow-ups. Our results showed differences in stigma, attitudes, and MHL between groups across time points. Intervention participants provided positive feedback, and the program was appraised as informative. CONCLUSIONS: Remote online delivery of a novel MHL educational program can effectively decrease mental health stigma, improve attitudes toward help-seeking, and increase the recognition and knowledge of mental health issues. Gaelic footballers with improved MHL may be better equipped to manage their mental health and cope with stressors, leading to improved mental health outcomes and overall mental well-being.

Do our movement skills impact our cognitive skills? Exploring the relationship between cognitive function and fundamental movement skills in primary school children.

OBJECTIVES: The literature suggests that there is a relationship between motor function and cognitive development however, few studies have explored the specific role of Functional Movement Skills on cognitive function. This research aimed to determine if Functional Movement Skills predict cognitive function, when accounting for confounding factors, in a sample of primary school children in Ireland. DESIGN: Cross-sectional. METHODS: Sixty primary school children (51.7 % girls, age range 7-12 years, mean age 9.9 ±â€¯1.28) were assessed in their Functional Movement Skill proficiency using the Test of Gross Motor Development-3rd Edition and a subtest of the Bruininks-Oseretsky Test of Motor Proficiency 2 Short Form (to assess balance). Participants also completed a series of cognitive tests which formed part of the Cambridge Neuropsychological Test Automated Battery. RESULTS: A series of hierarchical regression analyses were conducted whilst controlling for covariates (Age; Gender; Socio Economic Status). Attention Switching, Reaction Time, and Emotional Recognition were found to be associated with Overall Functional Movement Skills (Locomotor, Object Control, Stability). Overall Functional Movement Skills significantly accounted for 4.7 % of the variance in Simple Reaction Time (ΔR2 = 0.032; p = 0.13) whilst Stability significantly accounted for 5.5 % (ΔR2 = 0.055; p = 0.04) and 12.9 % (ΔR2 = 0.129; p = 0.00) of the variance in Simple Reaction Time and Emotional Recognition, respectively, after controlling for covariates. CONCLUSIONS: Overall Functional Movement Skills may be more related to reaction time than attention and spatial working memory, whilst stability may be more associated with emotional recognition. Further research is warranted. Greater comprehension of the impact of Functional Movement Skills on cognitive function in children can contribute to the development of more effective and efficient physical activity programmes, which can in turn contribute to and promote holistic child development.

Fear Avoidance After Injury and Readiness to Return to Sport in Collegiate Male and Female Gaelic Games Players.

BACKGROUND: Injuries are common in collegiate Gaelic games, and negative psychological responses to injury, such as fear avoidance and a lack of psychological readiness to return to sport, can affect players during their rehabilitation and their subsequent return to sport. Thus, identifying these responses in players can allow clinicians to address these issues during rehabilitation. This study aimed to examine fear avoidance and psychological readiness to return to sport in collegiate Gaelic games players. HYPOTHESIS: Collegiate Gaelic games players will experience similar levels of fear avoidance and psychological readiness to return to sport as other adult athletes. STUDY DESIGN: Cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: Male (n = 150) and female (n = 76) players from 1 Irish collegiate institution were recruited. Players that were injured over 1 collegiate season completed the Athlete Fear Avoidance Questionnaire (AFAQ) immediately after the injury and the Injury-Psychological Readiness to Return to Sport (I-PRRS) Scale once cleared to return to sport. An injury report form was also completed. The overall AFAQ (sum of 10 items) and I-PRRS (sum of 6 items/10) scores were calculated. RESULTS: Seventy-three injuries (n = 73) occurred, and injured players had a mean overall AFAQ and I-PRRS score of 22.6 ± 5.3 and 46.4 ± 8.8, respectively. Just less than half (47.9%) of players were deemed psychologically unready to return to sport when cleared physically. After severe injuries, significantly higher overall AFAQ scores than mild injuries (P = 0.01) and lower overall I-PRRS than moderate injuries (P < 0.0001) was noted. For the overall scores, no gender differences were observed. CONCLUSION: Fear avoidance and lowered confidence levels before return to sport occurs in collegiate Gaelic games players similar to other student-athletes. CLINICAL RELEVANCE: Identification of fear avoidance or low readiness to return to sport, particularly after serious injury, is important to implement psychosocial support during their rehabilitation.

A Pilot Study Exploring the Effects of Sleep Deprivation on Analogue Measures of Pilot Competencies.

INTRODUCTION: Sleep loss can result in cognitive, motor, and neurobehavioral impairments. In an aviation context, this can cause a serious threat to flight safety. Therefore, the study aimed to investigate the effects of 24-h sleep deprivation on mood, fatigue, and airline pilot competencies. METHODS: Seven subjects attended two 24-h testing periods, one with an 8-h sleep opportunity, and the other with no sleep opportunity (i.e., sleep deprivation). Subjects were required to complete a battery of mood, fatigue, and analogue measures of pilot competency tasks every 8 h (0 h, 8 h, 16 h, 24 h) throughout each testing period. RESULTS: While total mood disturbance was found to significantly increase (83.42, SD = 25.7), both objective (352.71, SD = 42.00) and subjective (34.85, SD = 8.82) fatigue were found to significantly decrease following 24-h sleep deprivation. Cognitive flexibility (757.45, SD = 58.48) and hand-eye coordination (dominant hand only) (60.28, SD = 3.86) were also negatively impacted following 24-h sleep deprivation. However, working memory and situation awareness were not significantly negatively impacted by the bout of sleep deprivation. DISCUSSION: Some pilot-specific task-related factors such as subjective fatigue, cognitive flexibility, and working memory were found to be particularly susceptible to sleep loss, with significant declines in performance observed following 16-h continuous wakefulness, suggesting reductions in optimal functioning following this period of wakefulness. Further investigation using more regular testing time points, employing additional pilot competencies, and using more aviation-specific tasks is warranted.O'Hagan AD, Issartel J, McGinley E, Warrington G.

Flying Into Depression.

A growing body of evidence suggests long work hours adversely affect mental health across a variety of domains. Mental health issues have been found to negatively affect work performance. This finding was highlighted in the aviation industry by the 2015 Germanwings incident in which 150 people died. Further investigation into work hours and their associated factors (e.g., demographic characteristics and experiences of sleep and fatigue in the cockpit) contributing to mental health issues among pilots is warranted. A cross-sectional survey investigating attitudes and experiences of fatigue was developed and distributed to commercial airline pilots. Results found pilots who reported typically spending longer hours on duty per week were twice as likely to report feeling depressed or anxious. Pilots' experiences of job-related sleep disturbance and fatigue may explain why pilots who typically spend long hours on duty each week are more likely to report feeling depressed or anxious.
