Zoomed out: digital media use and depersonalization experiences during the COVID-19 lockdown.

Depersonalisation is a common dissociative experience characterised by distressing feelings of being detached or 'estranged' from one's self and body and/or the world. The COVID-19 pandemic forcing millions of people to socially distance themselves from others and to change their lifestyle habits. We have conducted an online study of 622 participants worldwide to investigate the relationship between digital media-based activities, distal social interactions and peoples' sense of self during the lockdown as contrasted with before the pandemic. We found that increased use of digital media-based activities and online social e-meetings correlated with higher feelings of depersonalisation. We also found that the participants reporting higher experiences of depersonalisation, also reported enhanced vividness of negative emotions (as opposed to positive emotions). Finally, participants who reported that lockdown influenced their life to a greater extent had higher occurrences of depersonalisation experiences. Our findings may help to address key questions regarding well-being during a lockdown, in the general population. Our study points to potential risks related to overly sedentary, and hyper-digitalised lifestyle habits that may induce feelings of living in one's 'head' (mind), disconnected from one's body, self and the world.

Impact on mental health of the COVID-19 outbreak among community pharmacists during the sanitary lockdown period.

OBJECTIVES: COVID-19 outbreak can impact mental health including health care workers. The aim of this study was to assess the psychological impact of COVID-19 in French community pharmacists. MATERIAL AND METHODS: We carried out a postal-based survey to assess the psychological impact of COVID-19 in French owner community pharmacists based on three validated self-report questionnaires: Perceived Stress scale, Impact of Event Scale-revised and Maslach Burnout Inventory. RESULTS: The sample consists of 135 community pharmacists. Twenty-three pharmacists reported significant post-traumatic stress symptoms (17%). High burnout symptoms were found in 33 (25%), 46 (34.9%) and 4 (3%) participants. Females scored higher than males for all questionnaires (P=0.01). CONCLUSIONS: This study is the first study which showed the psychological impact of COVID-19 in community pharmacists. Based on validated self-report questionnaires, up to 35% of pharmacists reported psychological disturbances. Interventions to promote psychological well-being of healthcare workers need to be developing.

Factors Associated With Orthopaedic Resident Burnout: A Pilot Study.

INTRODUCTION: Burnout is an occupational hazard for physicians at all stages of training and medical practice. The purpose of the current study was to determine whether residency factors, with the use of an activity monitor, including the amount of exercise, have any impact on burnout among orthopaedic surgery residents in varying years of training. METHODS: Orthopaedic residents at a single institution were recruited immediately before beginning a new clinical rotation and followed for four weeks. On enrollment, the participants were given a wrist-worn activity monitor (Fitbit Flex) and instructed on its use for tracking physical activity. REDCap was used to collect burnout levels (as assessed by using the Maslach Burnout Inventory and the Patient Health Questionnaire-9), which were completed a total of five times, once at enrollment and weekly during the study period. RESULTS: Twenty-seven residents were enrolled, including 13 junior residents (interns and second years) and 14 senior residents (third, fourth, and fifth years). Seven residents were on fracture rotations, whereas 20 were not. As measured by using the Maslach Burnout Inventory, juniors were more emotionally exhausted (P = 0.01) and depersonalized (P = 0.027). No difference in the objective physical activity data as measured by using the Fitbit Flex and no difference in the self-reported hours of sleep were observed. Residents on orthopaedic trauma rotations also reported significantly higher rates of emotional exhaustion and depersonalization (P < 0.001) than other residents and were more physically active on average (P < 0.030). DISCUSSION: Although depersonalization and depression are common symptoms seen among orthopaedic surgery residents, this study demonstrated that quality of life improves markedly as they progress through their residency training. Residents on orthopedic trauma rotations have greater levels of emotional exhaustion and depersonalization. This pilot study suggests that burnout prevention programs should begin at the start of training to provide residents with strategies to combat and then reinforced while on orthopaedic trauma rotations. LEVEL OF EVIDENCE: Level III Diagnostic Study.

Burnout among Interventional Radiologists.

PURPOSE: To characterize burnout, as defined by high emotional exhaustion (EE) or depersonalization (DP), among interventional radiologists using a validated assessment tool. MATERIALS AND METHODS: An anonymous 34-question survey was distributed to interventional radiologists. The survey consisted of demographic and practice environment questions and the 22-item Maslach Burnout Inventory-Human Services Survey (MBI). Interventional radiologists with high scores on EE (≥ 27) or DP (≥ 10) MBI subscales were considered to have a manifestation of career burnout. RESULTS: Beginning on January 7, 2019, 339 surveys were completed over 31 days. Of respondents, 263 (77.6%) identified as male, 75 (22.1%) identified as female, and 1 (0.3%) identified as trans-male. The respondents were interventional radiology attending physicians (298; 87.9%), fellows (20; 5.9%), and residents (21; 6.2%) practicing at academic (136; 40.1%), private (145; 42.8%), and hybrid (58; 17.1%) centers. Respondents worked < 40 hours (15; 4.4%), 40-60 hours (225; 66.4%), 60-80 hours (81; 23.9%), and > 80 hours (18; 5.3%) per week. Mean MBI scores for EE, DP, and personal achievement were 30.0 ± 13.0, 10.6 ± 6.9, and 39.6 ± 6.6. Burnout was present in 244 (71.9%) participants. Identifying as female (odds ratio 2.4; P = .009) and working > 80 hours per week (odds ratio 7.0; P = .030) were significantly associated with burnout. CONCLUSIONS: Burnout is prevalent among interventional radiologists. Identifying as female and working > 80 hours per week were strongly associated with burnout.

PTSD and its dissociative subtype through the lens of the insula: Anterior and posterior insula resting-state functional connectivity and its predictive validity using machine learning.

Individuals with post-traumatic stress disorder (PTSD) typically experience states of reliving and hypervigilance; however, the dissociative subtype of PTSD (PTSD+DS) presents with additional symptoms of depersonalization and derealization. Although the insula is critical to emotion processing, its association with these contrasting symptom profiles is yet to be fully delineated. Accordingly, we investigated insula subregion resting-state functional connectivity patterns among individuals with PTSD, PTSD+DS, and healthy controls. Using SPM12 and PRONTO software, we implemented a seed-based resting-state functional connectivity approach, along with multiclass Gaussian process classification machine learning, respectively, in order to evaluate unique patterns and the predictive validity of insula subregion connectivity among individuals with PTSD (n = 84), PTSD+DS (n = 49), and age-matched healthy controls (n = 51). As compared to PTSD and PTSD+DS, healthy controls showed increased right anterior and posterior insula connectivity with frontal lobe structures. By contrast, PTSD showed increased bilateral posterior insula connectivity with subcortical structures, including the periaqueductal gray. Strikingly, as compared to PTSD and controls, PTSD+DS showed increased bilateral anterior and posterior insula connectivity with posterior cortices, including the left lingual gyrus and the left precuneus. Moreover, machine learning analyses were able to classify PTSD, PTSD+DS, and controls using insula subregion connectivity patterns with 80.4% balanced accuracy (p < .01). These findings suggest a neurobiological distinction between PTSD and its dissociative subtype with regard to insula subregion functional connectivity patterns. Furthermore, machine learning algorithms were able to utilize insula resting-state connectivity patterns to discriminate between participant groups with high predictive accuracy.

Abnormal Space Experiences in Persons With Schizophrenia: An Empirical Qualitative Study.

Abnormal space experience (ASE) is a common feature of schizophrenia, despite its absence from current diagnostic manuals. Phenomenological psychopathologists have investigated this experiential disturbance, but these studies were typically based on anecdotal evidence from limited clinical interactions. To better understand the nature of ASE in schizophrenia and attempt to validate previous phenomenological accounts, we conducted a qualitative study of 301 people with schizophrenia. Clinical files were analyzed by means of Consensual Qualitative Research, an inductive method for analyzing descriptions of lived experience. Our main findings can be summed up as follows: (1) ASEs are a relevant feature in schizophrenia (70.1% of patients reported at least 1 ASE). (2) ASE in schizophrenia are characterized by 5 main categories of phenomena (listed from more represented to less represented): (a) experiences of strangeness and unfamiliarity (eg "Everything appeared weird. Face distorted, world looks terrible, nasty"); (b) experiences of centrality/invasion of peripersonal space (eg "Handkerchief on scaffolding: message telling him something"); (c) alteration of the quality of things (eg "Buildings leaning down"); (d) alteration of the quality of the environment (eg "Person sitting six feet away seemed to be at an infinite distance"); and (e) itemization and perceptive salience (eg "All patients [in ward] have bright eyes"). (3) ASEs are much more frequent in acute (91.9%) than in chronic (28.15%) schizophrenia patients. Moreover, our findings further empirical support for phenomenological accounts of schizophrenia, including those developed by Jaspers, Binswanger, Minkowski, and Conrad, among others and provide the background for translational research.

Derealization symptoms according to the subjective visual vertical during unilateral centrifugation in patients with type 2 diabetes mellitus.

BACKGROUND: A recent study has shown variability on the perception of verticality during unilateral centrifugation among patients with type 2 diabetes mellitus; it is yet unknown if it is related to symptoms of unreality. OBJECTIVE: In patients with type 2 diabetes mellitus compared to age matched healthy volunteers, to assess depersonalization/derealization (DD) symptoms before and after unilateral centrifugation, according to the subjective visual vertical (SVV). METHODS: 47 patients with type 2 diabetes mellitus and 50 age matched healthy volunteers participated in the study. They replied to standardized questionnaires of symptoms related to balance, depression, and anxiety. Then, after neuro-otological evaluation, they completed a DD inventory before and after unilateral centrifugation (300°/s, 3.85 cm) with SVV estimation. RESULTS: Right/left asymmetric SVV during centrifugation was identified in 17 patients (36%) and no SVV change during centrifugation was identified in 6 patients (13%). Before centrifugation, patients with asymmetric SVV already reported some of the DD symptoms, while patients with no SVV change reported almost no DD symptoms. Unilateral centrifugation provoked an increase of DD symptoms in both healthy volunteers and the entire group of patients (repeated measures ANOVA, p < 0.01), except in the 6 patients with no SVV change. Before centrifugation, the DD score showed influence from the SVV subgroup and the evidence of depression (MANCoVA, p < 0.01); after centrifugation, which provoked asymmetry of the right/left utricular input, only the influence from depression persisted. No influence was observed from the characteristics of the subjects, including retinopathy, peripheral neuropathy (assessed by electromyography) or weight loss, or from the total score on the questionnaire of symptoms related to balance. CONCLUSIONS: In patients with type 2 diabetes mellitus and healthy volunteers, utricular stimulation by unilateral centrifugation may provoke DD symptoms, with an influence from depression. The results support that the aphysiological utricular input given by unilateral centrifugation may contribute to create a misleading vestibular frame of reference, giving rise to 'unreal' perceptions.

Relationship of Training in Acupuncture to Physician Burnout.

BACKGROUND: Physician burnout is an ongoing problem that affects both physician wellbeing and patient care. Burnout is characterized by emotional exhaustion and depersonalization. Studies have explored ways to prevent and alleviate burnout. Receiving training in acupuncture may reduce physician burnout. OBJECTIVE: The purpose of this study is to determine if acupuncture training is associated with less patient depersonalization and less emotional exhaustion among physicians. METHODS: These self-reported data were collected from a cross-sectional survey of family physicians at the Uniformed Services Academy of Family Physicians 2017 conference. Physicians answered questions regarding their level of acupuncture training as well as questions about burnout (depersonalization and emotional exhaustion). RESULTS: The overall response rate was 66% (325/492). Of these, 233 cases provided complete datasets. In a model controlling for years' practice and clinical pace, acupuncture training was significantly associated with decreased depersonalization, F (1, 194) = 5.82, P < .05. CONCLUSION: Study data show an association between decreased physician depersonalization and acupuncture training, suggesting acupuncture training may be a helpful strategy to reduce family physicians' depersonalization of patients.

Influence of medical shortage on GP burnout: a cross-sectional study.

BACKGROUND: Burnout is a common occurrence among GPs, decreasing quality of and access to care and impacting both physician and patient health. The link between burnout and low medical density has never been studied. OBJECTIVES: This study aimed to assess the prevalence of burnout and its related factors, including low medical density, among GPs. METHOD: We conducted a cross-sectional survey. A self-administered questionnaire was sent to all of the 1632 GPs in Normandy, France, in September 2015. The Maslach Burnout Inventory was used to assess the three burnout dimensions: emotional exhaustion (EE), depersonalization (DP) and low personal accomplishment (PA). RESULTS: In all, 501 GPs sent back their questionnaire (response rate: 30.7%); 487 questionnaires were analysed. Burnout had been experienced by 43.3% of the physicians in the sample. Nearly 24% of the respondents scored high EE, 27.3% scored high DP, and 13.3% scored low PA. Low medical density [odds ratios (OR): 2.16 (1.31-3.54)], and intent to quit [OR: 4.40 (2.59-7.47)] were strongly linked to the three burnout dimensions. Burnout was not linked with quantitative workload. CONCLUSION: Burnout among GPs was common. Low medical density and intent to quit were strong predictors of burnout. Given the current medical demographic crisis, these results highlight the relationship between burnout and medical shortage. Qualitative workload may have a more significant influence on burnout than quantitative workload. Recruiting more GPs is necessary, but may prove insufficient in fighting burnout. Preventive and curative actions are required, especially in areas with low medical density.

Is Balint training associated with the reduced burnout among primary health care doctors?

The aim of our study was to examine whether the participation in Balint group is associated with the reducing burnout syndrome among primary health care doctors. This investigation was conducted on a population of 210 doctors employed in primary health centers in Belgrade. Out of 210 doctors, 70 have completed Balint training for a period of at least 1 year, whereas 140 doctors have never attended this training (the Non-Balint group). The level of burnout among physicians was assessed with the Serbian translation of the original 22-item version of the Maslach Burnout Inventory - Human Services Survey which defines burnout in relation to emotional exhaustion, depersonalization and personal accomplishment. We found that 45.0% of the Non-Balint participants and 7.1% of the Balint-trained participants responded with symptoms of high level of emotional exhaustion, with a statistically significant difference (p < 0.001). In relation to depersonalization, 20% of the Non-Balint subjects were highly depersonalized compared to 4.4% of the Balint-trained subjects, with a statistically significant difference (p < 0.001). Regarding the personal accomplishment, 21.4% of the Non-Balint subjects and 7.1% of the Balint-trained subjects had a perception of low personal accomplishment, with a statistical significance (p < 0.001). In the multiple ordinal logistic model, with emotional exhaustion as a dependent variable, statistically significant predictor was female gender (OR = 2.51; p = 0.021), while Balint training was obtained as a protective factor (OR = 0.12; p < 0.001). Non-specialists were detected as a risk factor for depersonalization (OR = 2.14; p = 0.026) while Balint group was found as a protective factor (OR = 0.10; p < 0.001), according to the multiple ordinal logistic regression analysis. Regarding the reduced personal accomplishment, our results indicated that nonspecialists were at risk for this subdimension (OR = 2.09; p = 0.025), whereas Balint participants were protected (OR = 0.18; p < 0.001). Participation in Balint groups is associated with the reduced burnout syndrome among primary health care doctors.

Assessment of pediatric residents burnout in a tertiary academic centre.

OBJECTIVES: To study burnout among pediatric residents at King  Abdulazaiz University Hospital in Jeddah, Saudi Arabia. Methods: This is a cross-sectional survey that was administered to all pediatric residents enrolled in the Saudi Paediatric Board program (PGY1-PGY4) in a large tertiary academic hospital in the Western region of Saudi Arabia (King Abdulaziz University Hospital). The survey were sent via E-mail to 50 registered general pediatric residents.  Results: Seventy percent of the pediatric residents completed the survey. More than 70% of residents experiencing severe burnout. Forty-three percent suffering emotional exhaustion, 71.8% experiencing depersonalization and 40.6% suffering from low accomplishment. CONCLUSION: Burnout syndrome appear to be a serious threat to resident well-being in our program. Moreover, pediatric residents in our institute experienced higher levels of depersonalization than their peers nationally and internationally.

Quantification of burnout in emergency nurses: A systematic review and meta-analysis.

BACKGROUND: Previous studies showed increased levels of absenteeism, drug abuse, depression, and symptoms allied with burnout in emergency nurses. This meta-analysis aimed to quantify the three dimensions of burnout in emergency nurses and estimate the proportion of nurses who experience higher than tolerable levels of burnout. MATERIALS AND METHODS: A systematic search was conducted on PubMed, Scielo, Xueshu Baidu and Informa databases with a cut-off time between 1997 and 2017 to retrieve published papers in any language that had estimated the burnout levels in emergency nurses by using MBI scale. RESULTS: We identified a total of 11 eligible studies. The total mean estimate was moderate for emotional exhaustion (25.552), but clearly trending towards higher level, whereas depersonalization (10.383) and lack of personal accomplishment (30.652) showed higher burnouts levels. The proportion of emergency nurses suffering from high emotional exhaustion, high depersonalization, and low personal accomplishment was 40.5%, 44.3%, and 42.7%, respectively. CONCLUSION: Burnout is detrimental to achieving high-quality healthcare services and causes a loss of productivity. It is high time for nursing leader and management personnel to identify appropriate measures to counteract burnout.

Burnout syndrome in nurses working in palliative care units: An analysis of associated factors.

AIMS: To analyse the association between psychological, labour and demographic factors and burnout in palliative care nursing. BACKGROUND: There is a lack of published research evaluating burnout in palliative care nursing. METHODS: This observational cross-sectional study involved 185 palliative care nurses in Mexico. The primary variables were burnout defined by its three dimensions (emotional exhaustion, depersonalization and personal accomplishment). As secondary variables, psychological, labour and demographic factors were considered. A binary logistic regression model was constructed to determine factors associated with burnout. RESULTS: A total of 69 nurses experienced high emotional exhaustion (37.3%), 65 had high depersonalization (35.1%) and 70 had low personal performance (37.8%). A higher proportion of burnout was found in the participants who were single parents, working >8 hr per day, with a medium/high workload, a lack of a high professional quality of life and a self-care deficit. CONCLUSION: Our multivariate models were very accurate in explaining burnout in palliative care nurses. These models must be externally validated to predict burnout and prevent future complications of the syndrome accurately. IMPLICATIONS FOR NURSING MANAGEMENT: Nurses who present the factors found should be the focus of interventions to reduce work stress.

Public health and burnout: a survey on lifestyle changes among workers in the healthcare sector.

Burnout Syndrome is a condition which could most commonly be associated with negative effects on the quality of work and life. Some occupations are more likely to suffer from this syndrome, for example workers in the health sector. This survey was therefore conducted among hospital workers of the Marche Region in order to analyze levels of Burnout and any possible correlation of these levels with lifestyle changes. METHODS: The survey was carried out using a self-administered, anonymous questionnaire in two sections: the first consisted of the Maslach Burnout Inventory (MBI) and the second contained questions about the healthcare operator's lifestyle. The MBI investigates levels of Emotional Exhaustion (EE), Depersonalization (DP) and finally of Personal Accomplishment (RP) in respondents. Survey results were processed using descriptive statistics, applying the Chi-square statistic and an Odds Ratio (p<0.05). RESULTS: 53.4% of the questionnaire was duly completed. The scale with the highest incidence among interviewees was Depersonalization. Even though the high-level percentage for the DP and EE scale was equal to 22.3%, when adding the high-level percentage to the medium level percentage, the difference between low and medium-high level was found to be around 20% for all areas. Analyzing the correlation between lifestyle choices, and in particular the consumption of alcohol and smoking with Burnout Syndrome, a statistically significant Odds Ratio was observed in the DP scale vs alcohol (OR=4.67), the RP scale vs cigarette smoke (OR=2.50), and finally in the EE area vs cigarette smoke (OR=2.92). CONCLUSION: Our results are in line with other studies which show increasing levels of EE and DP in healthcare workers. Healthcare workers who have been in the same job for a considerable amount of time (15+ years) show the highest levels of EE and DP. Subjects with high levels of Depersonalization show a worrying exposure to alcohol abuse, while those with high levels of Emotional Exhaustion tend to make use of both alcohol and tobacco, demonstrating negative lifestyle choices; in spite of this, results for personal accomplishment being relatively low and therefore not cause for worry, subjects still show high levels of exposure to cigarette smoke.

Virtual reality improves embodiment and neuropathic pain caused by spinal cord injury.

OBJECTIVE: To investigate changes in body ownership and chronic neuropathic pain in patients with spinal cord injury (SCI) using multisensory own body illusions and virtual reality (VR). METHODS: Twenty patients with SCI with paraplegia and 20 healthy control participants (HC) participated in 2 factorial, randomized, repeated-measures design studies. In the virtual leg illusion (VLI), we applied asynchronous or synchronous visuotactile stimulation to the participant's back (either immediately above the lesion level or at the shoulder) and to the virtual legs as seen on a VR head-mounted display. We tested the effect of the VLI on the sense of leg ownership (questionnaires) and on perceived neuropathic pain (visual analogue scale pain ratings). We compared illusory leg ownership with illusory global body ownership (induced in the full body illusion [FBI]), by applying asynchronous or synchronous visuotactile stimulation to the participant's back and the back of a virtual body as seen on a head-mounted display. RESULTS: Our data show that patients with SCI are less sensitive to multisensory stimulations inducing illusory leg ownership (as compared to HC) and that leg ownership decreased with time since SCI. In contrast, we found no differences between groups in global body ownership as tested in the FBI. VLI and FBI were both associated with mild analgesia that was only during the VLI specific for synchronous visuotactile stimulation and the lower back position. CONCLUSIONS: The present findings show that VR exposure using multisensory stimulation differently affected leg vs body ownership, and is associated with mild analgesia with potential for SCI neurorehabilitation protocols.

Burnout After Patient Death: Challenges for Direct Care Workers.

CONTEXT: Direct care workers in long-term care can develop close relationships with their patients and subsequently experience significant grief after patient death. Consequences of this experience for employment outcomes have received little attention. OBJECTIVES: To investigate staff, institutional, patient, and grief factors as predictors of burnout dimensions among direct care workers who had experienced recent patient death; determine which specific aspects of these factors are of particular importance; and establish grief as an independent predictor of burnout dimensions. METHODS: Participants were 140 certified nursing assistants and 80 homecare workers who recently experienced patient death. Data collection involved comprehensive semistructured in-person interviews. Standardized assessments and structured questions addressed staff, patient, and institutional characteristics, grief symptoms and grief avoidance, as well as burnout dimensions (depersonalization, emotional exhaustion, and personal accomplishment). RESULTS: Hierarchical regressions revealed that grief factors accounted for unique variance in depersonalization, over and above staff, patient, and institutional factors. Supervisor support and caregiving benefits were consistently associated with higher levels on burnout dimensions. In contrast, coworker support was associated with a higher likelihood of depersonalization and emotional exhaustion. CONCLUSION: Findings suggest that grief over patient death plays an overlooked role in direct care worker burnout. High supervisor support and caregiving benefits may have protective effects with respect to burnout, whereas high coworker support may constitute a reflection of burnout.

The bodily self: Insights from clinical and experimental research.

This review article summarizes neuropsychological descriptions of abnormal body representations in brain-damaged patients and recent neuroscientific investigations of their sensorimotor underpinnings in healthy participants. The first part of the article describes unilateral disorders of the bodily self, such as asomatognosia, feelings of amputation, supernumerary phantom limbs and somatoparaphrenia, as well as descriptions of non-lateralized disorders of the bodily self, including Alice in Wonderland syndrome and autoscopic hallucinations. Because the sensorimotor mechanisms of these disorders are unclear, we focus on clinical descriptions and insist on the importance of reporting clinical cases to better understand the full range of bodily disorders encountered in neurological diseases. The second part of the article presents the advantages of merging neuroscientific approaches of the bodily self with immersive virtual reality, robotics and neuroprosthetics to foster the understanding of the multisensory, motor and neural mechanisms of bodily representations.

Working hours and common mental disorders in English police officers.

BACKGROUND: There is a paucity of evidence on working hours and their psychological correlates in police officers of the federated ranks in England. AIMS: An exploratory study to establish the extent to which a sample of English police officers worked long hours and the association between long working hours and common mental disorder (CMD). METHODS: Officers of the federated ranks (constable, sergeant, inspector) from two English county forces completed a questionnaire to report their typical weekly working hours and symptoms of CMD. We also collected socio- and occupational-demographic data. We defined long working hours as ≥49 h in a typical week in accordance with 48-h weekly limit specified in the 1993 European Directive on the Organisation of Working Time. We established associations between long working hours and self-reported CMDs using binary logistic regression to generate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for potential confounding variables. RESULTS: Twenty-seven per cent (n = 327/1226) of respondents reported long working hours. The ORs for psychological distress (OR 2.05, 95% CI 1.57-2.68), emotional exhaustion (OR 1.99, 95% CI 1.52-2.59), and depersonalization (OR 1.30, 95% CI 1.00-1.71) were significantly increased for long working hours after adjustment for socio- and occupational-demographic characteristics. CONCLUSIONS: More than one quarter of sampled police officers reported working long hours and were significantly more likely to report CMD. National and longitudinal research is required to confirm these findings, which suggest management of working hours may effectively promote psychological well-being.
