Prospective effects of work-time control on overtime, work-life interference and exhaustion in female and male knowledge workers
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Aims: Employee-based flexible working hours are increasing, particularly among knowledge workers. Research indicates that women and men use work–time control (WTC; control over time off and daily hours) differently: while men work longer paid hours, women use WTC to counteract work–life interference. In a knowledge-worker sample, we examined associations between WTC and overtime, work–life interference and exhaustion and tested if gender moderates the mediating role of overtime.Methods: The sample contained 2248 Swedish knowledge workers. Employing hierarchical regression modelling, we examined effects of control over time off/daily hours on subsequent overtime hours, work–life interference and exhaustion in general and in gender-stratified samples. Using conditional process analysis, we tested moderated mediation models.Results: Control over time off was related to less work–life interference (βmen=-0.117; CI95%: -0.237 to 0.003; βwomen=-0.253; CI95%: -0.386 to -0.120) and lower exhaustion (βmen=-0.199; CI95%: -0.347 to -0.051; βwomen=-0.271; CI95%: -0.443 to -0.100). For control over daily hours, estimates were close to zero. While men worked more overtime (42 minutes/week), we could not confirm gender moderating the indirect effect of control over time off/daily hours on work–life interference/exhaustion via overtime. Independent of gender, effects of control over time off on work–life interference were partly explained by working fewer overtime hours.Conclusion: Control over time off was related to lower exhaustion and better work–life balance (in particular for women). We found no evidence for men’s work–life interference increasing with higher WTC due to working more overtime. Knowledge workers’ control over time off may aid to prevent work–life interference and burnout.

Sleep disturbances : Consequences and comorbidities
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Sleep disorders are common in the general population, with insomnia and sleep-related breathing disorders being the most common disorders. Since sleep has many important functions, such as a role in consolidation of memories and learning, energy conservation, cardiovascular and immune system regulation, it is not surprising that the disruption of normal sleep may lead to negative health effects and various comorbidities. Aim: The overall aim of this thesis was to investigate the impact of disturbed sleep on various consequences and comorbidities. Methods and results: Papers I and II were based on the Sleep and Health in Women (SHE), a population-based prospective study of women, where a questionnaire was sent to women in 2000 and 2010. In paper I, the study cohort comprised 4,320 women <67 years of age who answered both questionnaires and had worked during the follow-up period. In women, having a long history of insomnia symptoms was associated with an increased risk of self-reported occupational accidents.In paper II, the 4,882 participants who answered the questions regarding nocturnal gastroesophageal reflux and snoring in both questionnaires were included in the study cohort. Women with nocturnal gastroesophageal reflux and snoring were at an increased risk of developing daytime sleepiness and to involuntarily fall asleep during the day. Paper III was based on the RHINE-cohort with participants from seven Northern European centers. The study cohort in paper III comprised the 2,568 smokers in the baseline study that also reported being smokers or former smokers in the follow-up study. It was found that having insomnia symptoms or excessive daytime sleepiness decreases the chance of long-term smoking cessation, and that smoking increases the risk of incident difficulties inducing sleep. Paper IV was the population-based, cross-sectional GA2LEN-survey which was conducted in four major Swedish cities. Paper IV included the 25,901 participants who answered questions regarding both snoring and insomnia symptoms. The combination of snoring and insomnia symptoms was associated with an increased risk of hypertension, asthma, chronic obstructive pulmonary disease, and daytime sleepiness. Conclusions: Disturbed sleep, due to varying causes, influences the risk of occupational accidents, on the chance of successful smoking cessation, on the risk of daytime sleepiness, hypertension, and obstructive lung disease. In clinical consultation, it is important to always inquire about disturbed sleep as it can have an impact on many aspects of health.

Tidskriftsartikel (refereegranskat)abstract
- We investigated whether self-ratings of health are affected by a symptom rating. A diary including a one-item self-rating of health ("pre-self-rated health"; 1 = excellent, 7 = very poor), a subsequent 26-item rating of symptoms, and thereafter a second (identical) health rating ("post-self-rated health") was completed by 820 persons 21 times. Self-rated health worsened significantly ( p < .0001) after the symptom rating, from 2.72 pre-self-rated health (95% confidence interval: 2.70-2.74) to 2.77 post-self-rated health (95% confidence interval: 2.75-2.79) and more so in persons who reported more symptoms ( b = .058, p < .05). The results support the notion that subjective health perception is influenced by attending to symptoms, especially so in persons with a high symptom burden.

- Bodily signals and how these are interpreted affect self-ratings of health. It is thus reasonable that appraisals of health are affected by imminent exposures and disease primes. We aimed to investigate whether self-ratings of health are affected by a symptom rating and if changes are substantiated in persons who report more symptoms. We used data from 813 persons who completed a questionnaire daily for 21 consecutive days. The questionnaire included a one-item self-rating of health (“pre-SRH”; 1 = excellent, 7 = very poor), a subsequent 26-item rating of physical and mental symptoms and thereafter a second (identical) self-rating of health (“post-SRH”). Paired t-tests were used to test for differences between pre-SRH and post-SRH. Mixed effect regression models were used to calculate the interaction effect of pre-SRH and symptom score on post-SRH adjusted for gender, age and if the person had been working that day (13545 observations). SRH worsened significantly (p <<.0001) after the symptom rating, from 2.72 pre-SRH (95%CI:−2.70–2.74) to 2.77 post-SRH (95%CI:2.75–2.79). There was a significant interaction between pre-SRH and symptoms on post-SRH so that persons who reported more symptoms changed their post-SRH rating to a higher degree than those who reported fewer symptoms, irrespective of their subjective health status. The results support the notion that subjective health perception is affected by focus of attention, and that the effect depends on level of symptoms.

Means of Sustainable Recruitment : The Importance of Selection Factors and Psychosocial Working Conditions in Predicting Work and Health Outcomes
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Research on selection factors often focuses on how to identify suitable candidates, while fewer studies have investigated the long-term effects of such selection factors once the suitable candidates have started working and faced the work situation. The overall aim of the present study was to examine the relative importance of selection factors (general intelligence, personality, and physical fitness), measured during recruitment, and psychosocial working conditions (e.g., workload, job control, and job challenge)for four different outcomes (job satisfaction, organizational citizenship behavior, occupational retention, and health). Data came from a longitudinal study of newly hired police officers in Sweden (N = 508), including information from both the recruitment process and a three-and-a-half year follow-up. Results of hierarchical multiple regression analyses show that psychosocial working conditions were far more important than the selection factors in predicting the four outcomes. The strong effects of psychosocial working conditions for new officers’ work-related attitudes and health suggest that employers, to ensure sustainability, need to focus on activities facilitating the organizational and professional entrance of newcomers by providing a sound work climate.

Tidskriftsartikel (refereegranskat)abstract
- Selection research has typically focused on how to identify suitable candidates, while less is known regarding the long-term effects of various selection factors once the suitable candidates have start-ed working. The overall aim of this study was to examine the relative importance of selection fac-tors (measured during recruitment), and psychosocial working conditions (once candidates started working) for four outcomes, namely (1) job satisfaction, (2) organizational citizenship behavior, (3) occupational retention, and (4) health. Data came from a longitudinal study of newly hired police officers in Sweden (N = 508), including recruitment data and a follow-up after 3.5 years. Results of hierarchical multiple regression analyses showed that psychosocial working conditions were more important than selection factors in predicting the four outcomes. The findings suggest that employers, to ensure sustainability, need to focus on activities that facilitate newcomers’ enter-ing in the organization and their professions by providing a sound work climate.

Tidskriftsartikel (refereegranskat)abstract
- Bus drivers often work irregular hours or split shifts and their work involves high levels of stress. These factors can lead to severe sleepiness and dangerous driving. This study examined how split shift working affects sleepiness and performance during afternoon driving. An experiment was conducted on a real road with a specially equipped regular bus driven by professional bus drivers.The study had a within-subject design and involved 18 professional bus drivers (9 males and 9 females) who drove on two afternoons; one on a day in which they had driven early in the morning (split shift situation) and one on a day when they had been off duty until the test (afternoon shift situation). The hypothesis tested was that split shifts contribute to sleepiness during afternoon, which can increase the safety risks. The overall results supported this hypothesis. In total, five of the 18 drivers reached levels of severe sleepiness (Karolinska Sleepiness Scale ≥8) with an average increase in KSS of 1.94 when driving in the afternoon after working a morning shift compared with being off duty in the morning. This increase corresponded to differences observed between shift workers starting and ending a night shift. The Psychomotor Vigilance Task showed significantly increased response time with split shift working (afternoon: 0.337. s; split shift 0.347. s), as did the EEG-based Karolinska Drowsiness Score mean/max. Blink duration also increased, although the difference was not significant. One driver fell asleep during the drive. In addition, 12 of the 18 bus drivers reported that in their daily work they have to fight to stay awake while driving at least 2-4 times per month. While there were strong individual differences, the study clearly showed that shift-working bus drivers struggle to stay awake and thus countermeasures are needed in order to guarantee safe driving with split shift schedules.

Bussförares arbetstider kopplat till trötthet
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Bussförare i kollektivtrafiken har ofta oregelbundna arbetstider och en arbetssituation som kan innebära hög stress. Dessa faktorer kan leda till allvarlig trötthet. Syftet med denna studie är att belysa hur arbetstiden påverkar sömn, stress, trötthet och körförmåga. Projektet omfattar fyra delstudier: enkätstudie, sömndagböcker och aktigrafi, analys av schemaläggning och ett experiment på riktig väg med bussförare. Hypoteserna var att tidiga morgonturer, delade skift, långa arbetsdagar och få timmars vila mellan arbetspassen bidrar till trötthet, stress och nedsatt körförmåga, som tillsammans kan leda till en sämre säkerhet. De övergripande resultaten stödjer dessa hypoteser. Generellt sett upplevs sömnighet och trötthet under körning som ett problem eftersom förarna anser att detta innebär nedsatt körförmåga, vilket ökar risken för incidenter och olyckor. Totalt 45 procent av förarna hade minst två gånger i månaden svårt att hålla sig vakna när de kör buss och 19 procent hade under det senaste decenniet varit inblandade i en incident där trötthet varit en bidragande orsak. Experimentet med delade skift med tidig start på morgonen stöder dessa rön. Rapporten avslutas med en lista med förslag.

Countermeasures for fatigue in transportation : a review of existing methods for drivers on road, rail, sea and in aviation
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim with this study was to gather knowledge about countermeasures for driver fatigue (including sleepiness) in road, rail, sea and air transportation. The knowledge has been used as an input for evaluating advantages and disadvantages with different countermeasures and to estimate their potential to be used regardless mode of transportation. The method used was a literature review and a workshop with experts from all transportation modes. At the workshop the effectiveness of countermeasures for a single mode, but also regardless mode were discussed and a ranking was done. The report discuss the potential of fighting fatigue among drivers for specific mode of transport but also from a more generic point of view, considering scheduling, model prediction of fatigue risk, legislation, a just culture, technical solutions, infrastructure, education, self-administered alertness interventions and fatigue risk management (FRM). The overall judgement was that a just culture, education, possibility to nap and schedules taking the humans limitations into consideration as the most effective countermeasures to fight fatigue, regardless mode of transportation.
