This randomized, controlled pilot trial evaluated the efficacy of a brief internet-based recovery training intervention targeting distressed employees. This pilot trial is one of the first to examine a brief recovery training program's efficacy, suggesting that employees across a wide range of professions could learn how to recover from elevated stress symptoms. This type of accessible and brief recovery intervention might shape the future of stress prevention, but more research is needed with larger samples before further conclusions can be drawn.

In recent years, work-related stress and burnout have received more attention, with a higher prevalence observed within the working population. Today, every fourth employee has experienced stress during most of their working days. Employees exposed to prolonged stress in their work situations experience more strain and suffer from poor well-being; higher risk of severe health implications, such as coronary artery disease; and problems in work participation, such as sickness absences, including long-term sick leave.

Empirical research suggests that recovery from work is important in reducing the negative effects on employees from stress and strain, as well as preserving their well-being and work performance. Recovery refers to the restoration processes during which a person's stress level returns to its pre-stress level. Recovery as a process refers to the activities and experiences that elicit change in stress and strain indicators. Recovery as an outcome captures a person's psychological or physiological state reached after a recovery period (e.g., at the end of a workday). Confirmatory factor analysis has proposed four distinct experiences in recovering from work processes: psychological detachment; relaxation; mastery; and control. Extant studies confirm that these experiences are related positively to well-being indicators such as the Recovery Experience Questionnaire.

Although extensive research has been devoted to stress intervention programs, and evidence suggest that these are effective in reducing stress within the working population, few studies have evaluated interventions aimed at stress prevention, e.g., by removing stressors and/or enhancing well-being factors, such as recovery. Most stress interventions have focused on reducing participants' cognitive, emotional, and behavioral symptoms when coping with stress. However, some promising results on stress prevention have been observed from recovery training programs.

Despite the evidence on the efficacy of stress management interventions and some promising results from recovery training interventions , only a small percentage of distressed employees actually receive stress interventions. This calls for further development and evaluation of interventions that are accessible and has the potential in preventing chronic stress in the working population.

The internet has the potential to disseminate interventions broadly, and a growing body of literature has demonstrated internet-based stress interventions' efficacy, with small to moderate effects on outcomes from stress, burnout, insomnia, depression, and anxiety.

The present, controlled pilot study aim to examine the efficacy of a brief, five-week, internet-based recovery training program for employees experiencing elevated symptoms of stress and/or a stress-related disorder burnout in a randomized, controlled pilot trial. We hypothesize that the internet-based recovery program would produce greater improvements in recovery experiences (primary outcome) compared with a wait-list control group. We also hypothesize that the intervention group will differ with regard to important health-related (perceived stress, burnout, exhaustion, depression, alcohol consumption, and quality of life) and work-related (work experience, work ability, sickness absences) outcomes. Finally, we investigate whether the initially achieved changes in the intervention group would remain stable at six- and 12-month follow-ups.
