    Input: Introduction Return to work ( RTW ) of employees on sick leave for common mental disorders may require a multidisciplinary approach . This article aims to assess time to RTW after a psychiatric consultation providing treatment advice to the occupational physician ( OP ) for employees on sick leave for common mental disorders in the occupational health ( OH ) setting , compared to care as usual ( CAU ) . Methods Cluster r and omized clinical trial evaluating patients of 12 OPs receiving consultation by a psychiatrist , compared to CAU delivered by 12 OPs in the control group . 60 patients suffering from common mental disorders and ≥ six weeks sicklisted were included . Follow up three and six months after inclusion . Primary outcome measure was time to RTW . Intention- to-treat multilevel analysis and a survival analysis were performed to evaluate time to RTW in both groups . Results In CAU , referral was the main intervention . Both groups improved in terms of symptom severity and quality of life , but time to RTW was significantly shorter in the psychiatric consultation group . At three months follow up , 58 % of the psychiatric consultation group had full RTW versus 44 % of the control group , a significant finding ( P = 0.0093 ) . Survival analysis showed 68 days earlier RTW after intervention in the psychiatric consultation group ( P = 0.078 ) compared to CAU . Conclusion Psychiatric consultation for employees on sick leave in the OH setting improves time to RTW in patients with common mental disorders as compared to CAU . In further research , focus should be on early intervention in patients with common mental disorders on short sick leave duration  . Psychiatric consultation might be particularly promising for improvement of RTW in those patients . Trial registration number IS RCT N : Background To reduce the duration of sick leave and loss of productivity due to common mental disorders ( CMDs ) , we developed a return-to-work programme to be provided by occupational physicians ( OPs ) based on the principles of exposure in vivo ( RTW-E programme ) . This study evaluates this programme 's effectiveness and cost-effectiveness by comparing it with care as usual ( CAU ) . The three research questions we have are : 1 ) Is an RTW-E programme more effective in reducing the sick leave of employees with common mental disorders , compared with care as usual ? 2 ) Is an RTW-E programme more effective in reducing sick leave for employees with anxiety disorders compared with employees with other common mental disorders ? 3 ) From a societal perspective , is an RTW-E programme cost-effective compared with care as usual ? Methods / design This study was design ed as a pragmatic cluster-r and omized controlled trial with a one-year follow-up and r and omization on the level of OPs . We aim ed for 60 OPs in order to include 200 patients . Patients in the intervention group received the RTW-E programme .  Patients in the control group received care as usual .  Eligible patients had been on sick leave due to common mental disorders for at least two weeks and no longer than eight weeks . As primary outcome measures , we calculated the time until full return to work and the duration of sick leave . Secondary outcome measures were time until partial return to work , prevalence rate of sick leave at 3 , 6 , 9 , and 12 months ' follow-up , and scores of symptoms of distress , anxiety , depression , somatization , and fatigue ; work capacity ; perceived working conditions ; self-efficacy for return to work ; coping behaviour ; avoidance behaviour ; patient satisfaction ; and work adaptations . As process measures , we used indices of compliance with the intervention in the intervention group and employee-supervisor communication in both groups . Economic costs were calculated from a societal perspective . The total costs consisted of the costs of consuming health care , costs of production loss due to sick leave and reduced productivity , and out-of-pocket costs of patients for travelling to their OP . Discussion The results will be published in 2009 . The strengths and weaknesses of the study protocol are discussed . Trial registration IS RCT OBJECTIVE High levels of work-related stress are associated with increased absenteeism from work and reduced work ability . In this study , we investigated the effects of a stress management intervention on absenteeism and return to work . METHODS We r and omized 102 participants into either the intervention or wait-list control ( WLC ) group . The intervention group received the intervention in weeks 1 - 16 from baseline , and the WLC group received the intervention in weeks 17 - 32 . Self-reported data on absenteeism ( number of days full- or part-time absent from work within the previous three months ) were obtained at 16 , 32 , and 48 weeks follow-up . Register-based data on long-term absence from work were drawn from the Danish public transfer payments ( DREAM ) data base from baseline and 48 weeks onwards . The DREAM data base contains weekly information on long-term sickness absence compensation . The threshold to enter DREAM is sick leave for two consecutive weeks . RESULTS At follow-up in week 16 , self-reported absenteeism in the intervention group [ median 11 days ( range 3 - 25 ) ] was lower ( P=0.02 ) than in the WLC group [ median 45 days ( range 19 - 60 ) ] , corresponding to a 29 % [ 95 % confidence interval ( 95 % CI ) 5 - 52 ] reduction . On register-based data ( cumulated weeks in DREAM , weeks 1 - 16 ) , the intervention group median [ 6 weeks ( range 0 - 11 ) ] was lower than that of the WLC group [ median 12 weeks ( range 8 - 16 ) ] , though not significantly ( P=0.06 ) , corresponding to a 21 % ( 95 % CI 0 - 42 ) reduction . For return to work , a hazard ratio of 1.58 ( 95 % CI 0.89 - 2.81 ) favoring the intervention group was found ( P=0.12 ) . CONCLUSIONS The intervention reduces self-reported absenteeism from work . A similar trend was found from register-based records . No conclusive evidence was found for return to work Background Considering the high costs of sick leave and the consequences of sick leave for employees , an early return-to-work of employees with mental disorders is very important . Therefore , a workplace intervention is developed based on a successful return-to-work intervention for employees with low back pain . The objective of this paper is to present the design of a r and omized controlled trial evaluating the cost-effectiveness of the workplace intervention compared with usual care for sick-listed employees with common mental disorders . Methods The study is design ed as a r and omized controlled trial with a follow-up of one year . Employees eligible for this study are on sick leave for 2 to 8 weeks with common mental disorders . The workplace intervention will be compared with usual care . The workplace intervention is a stepwise approach that aims to reach consensus about a return-to-work plan by active participation and strong commitment of both the sick-listed employee and the supervisor . Outcomes will be assessed at baseline , 3 , 6 , 9 and 12 months . The primary outcome of this study is lasting return-to-work , which will be acquired from continuous registration systems of the companies after the follow-up . Secondary outcomes are total number of days of sick leave during the follow-up , severity of common mental disorders , coping style , job content , and attitude , social influence , and self-efficacy determinants . Cost-effectiveness will be evaluated from the societal perspective . A process evaluation will also be conducted . Discussion Return-to-work is difficult to discuss in the workplace for sick-listed employees with mental disorders and their supervisors . Therefore , this intervention offers a unique opportunity for the sick-listed employee and the supervisor to discuss barriers for return-to-work . Results of this study will possibly contribute to improvement of disability management for sick-listed employees with common mental disorders . Results will become available in 2009.Trial registration IS RCT Background Workplace mental health promotion ( WMHP ) aims to prevent and effectively manage the social and economic costs of common mental illnesses such as depression . The mental health of managers and employees within small-medium enterprises ( SMEs ) is a neglected sector in occupational health research and practice , despite the fact that this sector is the most common work setting in most economies . The availability and propensity of SME staff to attend face-to-face training/therapy or workshop style interventions often seen in corporate or public sector work setting s is a widely recognised problem . The ' Business in Mind ' program employs a DVD mode of delivery that is convenient for SME managers , particularly those operating in regional and remote areas where internet delivery may not be optimal . The objective of the intervention program is to improve the mental health of SME managers , and examine whether employees of managers ' whose mental health improves , report positive change in their psychosocial work environment . The mechanisms via which we aim to improve managers ' mental health are through the development of their psychological capital ( a higher order construct comprised of hope , self efficacy , resilience and optimism ) and their skills and capacities for coping with work stress . Methods / Design The effectiveness of two versions of the program ( self administered and telephone facilitated ) will be assessed using a r and omised trial with an active control condition ( psychoeducation only ) . We aim to recruit a minimum of 249 managers and a sample of their employees . This design allows for 83 managers per group , as power analyses showed that this number would allow for attrition of 20 % and still enable detection of an effect size of 0.5 . The intervention will be implemented over a three month period and postal surveys will assess managers and employees in each group at baseline , intervention completion , and at 6 month follow up . The intervention groups ( managers only ) will also be assessed at 12 and 24 month follow-up to examine maintenance of effects . Primary outcomes are managers ' levels of psychological capital ( hope , resilience , self-efficacy and optimism ) , coping strategies , anxiety and depression symptoms , self-reported health , job satisfaction and job tension . Secondary outcomes are participating managers subordinates ' perceptions of manager support , relational justice , emotional climate and job tension . In order to provide an economic evaluation of the intervention , both employees and manager rates of absenteeism and presenteeism will also be assessed . Discussion The intervention being trialled is expected to improve both primary and secondary outcomes . If proven efficacious , the intervention could be disseminated to reach a much larger proportion of the business community . Trial registration Current controlled trials IS RCT N Background Major depressive disorder is among the medical conditions with the highest negative impact on work outcome . However , little is known regarding evidence -based interventions targeting the improvement of work outcomes in depressed employees . In this paper , the design of a r and omized controlled trial is presented in order to evaluate the effectiveness of adjuvant occupational therapy in employees with depression . This occupational intervention is based on an earlier intervention , which was design ed and proven effective by our research group , and is the only intervention to date that specifically targets work outcome in depressed employees . Methods / Design In a two-arm r and omized controlled trial , a total of 117 participants are r and omized to either ' care as usual ' or ' care as usual ' with the addition of occupational therapy . Patients included in the study are employees who are absent from work due to depression for at least 25 % of their contract hours , and who have a possibility of returning to their own or a new job .  The occupational intervention consists of six individual sessions , eight group sessions and a work-place visit over a 16-week period . By increasing exposure to the working environment , and by stimulating communication between employer and employee , the occupational intervention aims to enhance self-efficacy and the acquisition of more adaptive coping strategies . Assessment s take place at baseline , and at 6 , 12 , and 18-month follow-ups . Primary outcome measure is work participation ( hours of absenteeism and time until work resumption ) . Secondary outcome measures are work functioning , symptomatology , health-related quality of life , and neurocognitive functioning . In addition , cost-effectiveness is evaluated from a societal perspective . Finally , mechanisms of change ( intermediate outcomes ) and potential patient-treatment matching variables are investigated . Discussion This study hopes to provide valuable knowledge regarding an intervention to treat depression , one of the most common and debilitating diseases of our time . If our intervention is proven ( cost- ) effective , the personal , economic , and health benefits for both patients and employers are far-reaching . Trial registration Background Common mental disorders , such as depression , anxiety disorder , and adjustment disorder , have emerged as a major public and occupational health problem in many countries . These disorders can have severe consequences such as absenteeism and work disability . Different interventions have been developed to improve the return-to-work of employees with common mental disorders , but still a large proportion of employees experiences health and work problems after their return-to-work . For this reason , the SHARP-at work intervention is developed to prevent a relapse of sickness absence among employees who have returned to work after a period of sickness absence because of common mental disorders . We aim to evaluate the effectiveness , cost-benefit and process of the intervention compared to care as usual . Methods / Design The study is design ed as a cluster-r and omised controlled trial with r and omisation at the level of the occupational physician . Employees who have returned to work after a period of sickness absence because of a common mental disorder are included in the study . Employees in the intervention group will receive the SHARP-at work intervention . The intervention focusses on active guidance of employees by occupational physicians  during the first weeks of work after sickness absence . Employees in the control group  will receive care as usual . Outcomes will be assessed at baseline and at 3 , 6 , and 12 months follow-up . The primary outcome is cumulative recurrent sickness absence days . Secondary outcome measures are mental health , work functioning , and coping . Adherence to the protocol , communication between stakeholders , and satisfaction with the treatment are the process measures assessed in both study groups . Cost-benefit is calculated from a societal perspective . Finally , prognostic factors for a relapse of sickness absence are investigated . Discussion This study goes beyond return-to-work by focussing 
    Output:
    
We found moderate- quality evidence that CBT did not significantly reduce time until partial RTW and low- quality evidence that it did not significantly reduce time to full RTW compared with no treatment .
Moderate- quality evidence showed that PST significantly enhanced partial RTW at one-year follow-up compared to non- guideline based care but did not significantly enhance time to full RTW at one-year follow-up .
