Two hundred and two nurses (95% female age M = 35.28 years ± SD = 12) participated (42% of eligible staff). Sick leave data were collected from archival records from the Human Resources Department. Staff completed an online survey comprising demographic questions, the Shift Work Disorder Questionnaire, Patient Health‐9 and the General Anxiety Disorder‐7 scale. This study aimed to evaluate the association between shift work disorder and mental health in hospital‐based nurses. Registry: Australian New Zealand Clinical Trials Registry Identifier: ACTRN12616000369426. Future intervention trials should consider including both sleep and mental health interventions, strategies to avoid between group contamination and the duration of programs for optimal behavioral modification. Improvements in sleep hygiene, insomnia, depression, and anxiety severity were seen for both groups.
Healthiest shift work schedule trial#
This SWD intervention trial did not reduce sick leave compared to the active control but there was an improvement. control p=.079) and FOSQ (p=.001 control p=.056) improved only for the intervention.
Improvements were seen in insomnia (p<.0001*), and depression (intervention, p=<.0001*, control, p=.023) in both groups, but were not significantly different between programs. There was no significant reduction in sick leave between intervention and control wards (mean difference=1.2 days, p=.063). A total of 149 nurses, across 16 wards (96% female, 34.66 ± 11.99 years) completed both baseline and follow-up questionnaires (23.9% were high risk SWD). Secondary outcomes were SWD risk, sleep hygiene, insomnia, depression, and anxiety. The primary outcome was ward-based sick leave. Participants identified as high risk for SWD underwent one of two 8-week programs a shift work individualized management program (S.W.I.M.) or an active control. The aim of this study was to deliver and evaluate a shift work individual management coaching program, focusing on sleep education, promoting good sleep hygiene, and providing individualized behavioral strategies to cope with shift schedules.Ī clustered randomized controlled trial of sleep education and sleep disorders screening was undertaken, based on hospital wards at a tertiary hospital in Melbourne, Australia. SWD can lead to impairments in cognitive function, physical and mental health, and reduced productivity and increased risk of workplace injury. While insomnia and sleepiness symptoms are common in shift workers, 20-30% experience more severe symptoms and meet the criteria for shift work disorder (SWD). Validation of a questionnaire to screen for shift work disorder. CITATION: Barger LK Ogeil RP Drake CL O'Brien CS Ng KT Rajaratnam SMW. This Shiftwork Disorder Screening Questionnaire may be appropriate for use in primary care settings to aid in the diagnosis of SWD. A final 4-item questionnaire has 89% positive predictive value and 62% negative predictive value (sensitivity = 0.74 specificity = 0.82).
Healthiest shift work schedule series#
Responses to the items in the questionnaire were entered into a series of discrimination function analyses to determine the diagnostic value of the items and the fewest number of questions with the best predictive value. The physician assessment of SWD was guided by a flow chart that operationalized the ICSD-2 criteria for SWD. Shift workers completed a 26-item questionnaire and were evaluated by a sleep specialist (physician) who diagnosed them as either positive or negative for SWD. We sought to develop and validate a questionnaire to screen for high risk of SWD in a shift working population. Shift work disorder (SWD), a primary (circadian rhythm) sleep disorder indicated by excessive daytime sleepiness and/or insomnia associated with a shiftwork schedule, is under-recognized by primary care physicians. Working during the overnight hours, early morning start times, and variable or rotating schedules present a challenge to the circadian system, and these shifts are associated with adverse health and safety consequences. At least 15% of the full-time work force is shift workers.
