  Background A higher sense of mastery of doctors’ clinical work could benefit not only their own mental health but also their work performance and patient care. However, we know little about factors associated with perceived mastery of clinical work among physicians. Our aim was therefore to study characteristics of those with stable low levels and of those with increased levels of mastery over a period of ten years of medical practice. Methods N = 631 doctors were surveyed in their final year of medical school in 1993/94 (T1) and 10 (T2), 15 (T3) and 20 (T4) years later. Low and increased perceived mastery of clinical work were measured between T2, T3 and T4. Response rates for all items measuring low and increased mastery were 238/522 (46%) and 256/522 (49%) respectively. The following explanatory variables were included: demographics, medical school factors, personality and contextual work-related and non-work-related factors. Results N = 73 (31%) of the doctors reported stable low mastery from T2 to T4. The following variables were significantly associated with low mastery in the adjusted analyses: vulnerability (OR: 1.30, P < .000, CI: 1.12 to 1.50), drinking alcohol to cope with stress during medical school (OR: 2.66, P = .04, CI: 1.03 to 6.85) and social support (OR: 0.78, P = .002, CI: 0.66 to 0.91). N = 39 (15%) reported increased mastery during the ten-year period from T2 to T4. Perceived job demands (OR: 0.66, P = .02, CI: 0.45 to 0.98) and taking up a leading position (OR: 3.04, P = .01, CI: 1.31 to 7.07) were associated with increased mastery after adjustment. Conclusions Stable low sense of mastery over time is associated with having a vulnerable personality, a history of having used alcohol to cope with stress during medical school and lack of contemporary social support. Conversely, increased sense of mastery is associated with taking up a leading position and having the perception that job demands are decreasing over time. These findings indicate that perceived mastery of clinical work may not be a trait, but a state modifiable over time

  Background Lifestyle changes are important for prevention and treatment of many common diseases, and doctors have an important role in the lifestyle counselling of patients. It is important to know more about factors influencing lifestyle counselling. Aim To investigate the frequency of counselling about physical activity compared to that about alcohol habits; the impact of doctors’ own physical activity and alcohol habits on patient counselling about these lifestyle dimensions; and whether perceived mastery of clinical work or vulnerable personality have a confounding or moderating effect on these associations. Design & setting In this nationwide cohort survey, a total of 978 doctors in Norway were surveyed by postal questionnaires in 1993/94 and 2014. The response rate was 562/978 (57%). Method The outcome variables were questions on frequency of asking about alcohol and exercise habits. Explanatory variables were questions on doctors’ own exercise habits, drinking habits (using Alcohol Use Disorders Identification Test [AUDIT]), perceived mastery of clinical work, vulnerable personality, and specialty. Associations were studied by linear regression analysis. Results Of the 526 responders, 307 (58%) reported asking usually/often about exercise habits, while n = 140/524 (27%) usually/often asked about alcohol habits. A doctor's own physical activity level was associated with frequency of asking about physical activity (unstandardised regression coefficient [B] = 0.07; 95% confidence intervals [CI] = 0.01 to 0.13). There were no significant associations between doctors' own lifestyle habits and counselling on alcohol habits. Doctors with low levels of vulnerability asked more frequently about physical activity, regardless of their own physical activity habits (F = 2.41, P = 0.048). Conclusion Doctors’ own lifestyles influenced their preventive counselling about physical activity, but not about alcohol. Vulnerability moderated these effects, indicating the importance of early interventions to help doctors with a vulnerable personality to handle negative criticism from patients

  Background: Doctor –certified sick leave is prevalent in the health and social sector. We examined whether the higher risk of doctor-certified sick leave in women in health and social occupations compared to women in other occupations was explained by particular work-related psychosocial and mechanical risk factors. Methods: A randomly drawn cohort aged 18–69 years from the general population in Norway was surveyed in 2009 (n = 12,255, response at baseline = 60.9 %), and was followed up in the national registry of social transfer payments in 2010. Eligible respondents were women registered with an active employee relationship for ≥100 actual working days in 2009 and 2010 (n = 3032). Using this sample, we compared health and social workers (n = 661) with the general working population (n = 2371). The outcome of interest was long-term sick leave (LTSL) ≥21 working days during 2010. Eight psychosocial and eight mechanical factors were evaluated. Results: After adjusting for age, previous LTSL, education and working hours/week, women in health and social occupations had a higher risk for LTSL compared with women in the general working population (OR = 1.42, 95 % CI = 1.13–1.79; p = 0.003). After adjusting for psychosocial and mechanical factors, 70 % of the excess risk for LTSL was explained compared with the initial model. The main contributory factors to the increased risk were threats of violence and violence, emotional demands and awkward lifting. Conclusions: Psychosocial and mechanical factors explained much of the excess risk for LTSL in women in health and social occupations compared with working women in general. Psychosocial risk factors were the most important contributors.

  BAKGRUNN Norske sykehusleger fremholder verdien av å jobbe hardt og effektivt og ha stor grad av tilstedeværelse på jobb. Dette bidrar til å skape sosiale normer som virker styrende for atferd innen profesjonskulturen. Det er viktig å undersøke hvilke konsekvenser disse verdiene kan få, når legen også skal ivareta egne behov. MATERIALE OG METODE Vi gjennomførte åtte fokusgruppeintervjuer og tre individuelle intervjuer blant til sammen 48 overleger og leger under spesialisering, som jobbet innen kirurgi, psykiatri og indremedisin ved to ulike sykehus. Totalt N = 48, 56 % kvinner. Intervjuene ble analysert med systematisk tekstkondensering. RESULTATER Når norske sykehusleger ønsker å fremstå som gode leger, opplever de at det får konsekvenser for samspillet med legekollegiet, ledelsen og balansen mellom hjem og jobb. Interessekonflikter fremkom mellom overleger og leger i spesialisering. Ledelsesinitiativ for å håndtere fravær, livsfasetilpasning av legejobben og økt lederengasjement blant leger var tiltak som ble foreslått. FORTOLKNING Bedre gjensidig kunnskap mellom leger og ledelse om hverandres verdier og ansvarsområder vil være viktige premisser for å kunne gjøre strukturelle endringer, for eksempel bedre planlegging av fravær og mulighet for livsfasetilpasning i arbeidsplaner.

  BAKGRUNN Legene i dagens samfunn møter mange kryssende interesser fra blant andre kolleger, pasienter og arbeidsgivere. Det er forsket mye på utvikling og regulering av den medisinske profesjonen. Imidlertid er det forsket mindre på legers egne opplevelser av hva det innebærer å være en god lege. MATERIALE OG METODE Vi gjennomførte åtte fokusgruppeintervjuer og tre individuelle intervjuer blant overleger og leger i spesialisering som jobbet innenfor kirurgi, psykiatri og indremedisin, ved to ulike sykehus. Totalt N = 48, 56 % kvinner. Intervjuene ble analysert med systematisk tekstkondensering. RESULTATER «Faglig dedikasjon» vist ved «høy grad av tilstedeværelse på jobb» og «stor arbeidskapasitet» var sentrale temaer for gode leger. Stor arbeidskapasitet ble definert som viljen til å strekke seg langt, jobbe overtid og jobbe effektivt. Overlegene opplevde det å være lege mer som en «livsstil», mens leger i spesialisering i større grad så på det som en «jobb». FORTOLKNING Norske sykehusleger ønsker å fremstå som faglig dedikerte. Dette kan de vise gjennom en sterk vilje til å jobbe hardt og effektivt med pasientarbeid og samtidig strekke seg langt for å være til stede utover regulær arbeidstid.

  Objectives: The aim of the current study was to elucidate prospective effects of both shift schedules and work environment on mental distress. Methods: A total of 2059 nurses participated at baseline (38.1%), and 1582 nurses completed wave 2 of the survey (76.8%). Psychosocial work factors were measured by the General Nordic Questionnaire for Psychological and Social factors at work and the Swedish Demand–Control–Support Questionnaire. Mental distress was measured by Hospital Anxiety and Depression Scale. Results: Shiftwork was not associated with ‘‘caseness’’ anxiety or depression. Effects of shiftwork on mental distress were not moderated by psychosocial work factors. Mental distress predicted role clarity, role conflict, fair leadership, and social support. Job demands predicted symptoms of depression. Conclusions: Whether psychosocial working conditions buffer mental health effects of shiftwork remains undecided. Prospective studies with multiple measurement points are needed to elucidate potential mutual relationships between work factors and mental distress.

  Background: Doctor-certified sick leave differs substantially across sectors, and among health and social workers, in particular, there is an increased risk. Previous studies have shown that work environmental factors contribute to sick leave. Hence, the identification of specific organizational and psychosocial risk factors for long- term sick leave, taking into account potential confounding related to mechanical risk factors such as lifting and awkward body postures, will be of importance in the work of prevention. Methods: A randomly drawn population sample of Norwegian residents was interviewed about working conditions in 2009 (n = 12,255; response rate 60.9%). Female health and social care workers (n = 925) were followed in a national registry for subsequent sickness absence during 2010. The outcome of interest was doctor-certified sick leave of 21 days or more (long-term sick leave). Eleven work-related psychosocial and organizational factors were evaluated. Results: In total, 186 persons (20.1%) were classified with subsequent long-term sick leave. After thoroughly adjusting for competing explanatory variables, the most consistent predictors for long-term sick leave were violence and threats of violence (OR = 1.67; 95% CI 1.14–2.45). The estimated population attributable risk for violence and threats of violence was 13%. Conclusions: The present study among female health and social care workers revealed a substantial relationship between self-reported violence and threats of violence and subsequent long- term sick leave.

  This study investigated associations between individual and work-related factors and perceived mastery of work among offshore shift workers. 2,406 employees of a Norwegian petroleum company were invited to participate. A web-based survey was used and 1336 completed questionnaires were returned (56%). Mastery of work was assessed using QPS Nordic Mastery Scale and the results were compared with a sample from the QPS Nordic study. Individual factors adjusted for were age, gender, marital status and personality. The following work-related factors were included: demands, control, support, night work and shift work home interference. Female offshore shift workers reported higher levels of perceived mastery of work compared with women in the comparison sample. The following variables were independently associated with perceived mastery of work: female gender (β=0.10, p=0.008), decisional demands (β=0.13, p<0.001), control (β=0.05, p=0.009), social support (β=0.07, p<0.001), shift-work locus of control (β=0.04, p=0.005) and neuroticism (β=–0.29, p<0.001). Post hoc analyses showed no sex differences in perceived mastery in two separate work positions on the platforms. Work-related variables and personality explained 55% and 45% respectively of the total variance (R2=0.22) explained by the final model. Female petroleum offshore workers reported somewhat higher levels of mastery of work than their male colleagues, however, this may be due to different work positions. Work-related factors accounted for about half of the explained variance and decisional demands, control and support remained statistically significant after controlling for personality.

  Objective This study aimed to investigate the association between individual and psychosocial work factors and mental distress among offshore shift workers in the Norwegian petroleum industry. Methods All 2406 employees of a large Norwegian oil and gas company, who worked offshore during a two-week period in August 2006, were invited to participate in the web-based survey. Completed questionnaires were received from 1336 employees (56% response rate). The outcome variable was mental distress, assessed with a shortened version of the Hopkins Symptom Checklist (HSCL-5). The following individual factors were adjusted for: age, gender, marital status, and shift work locus of control. Psychosocial work factors included: night work, demands, control and support, and shift work–home interference. Results The level of mental distress was higher among men than women. In the adjusted regression model, the following were associated with mental distress: (i) high scores on quantitative demands, (ii) low level of support, and (iii) high level of shift work–home interference. Psychosocial work factors explained 76% of the total explained variance (adjusted R²=0.21) in the final adjusted model. Conclusions Psychosocial work factors, such as quantitative demands, support, and shift work–home interference were independently associated with mental distress. Shift schedules were only univariately associated with mental distress.
