RESTART: a stepped-care approach to facilitate return to work for employees with psychological distress: design of a randomized controlled trial.

BACKGROUND: Common mental health problems, such as stress, anxiety and depression, are highly prevalent among workers and often lead to long-term absenteeism and work disability. Effective elements found in previous researched interventions were to explicitly focus on return to work (RTW) and not solely on symptom reduction, to take into account the employees' cognition towards RTW and to include the workplace environment. Based on these elements, a stepped-care approach was developed. The aim of this paper is to present the study design of a randomized controlled trial (RESTART), evaluating the effectiveness of the stepped-care approach on lasting RTW and the implementation process. METHODS: RESTART is a randomized controlled trial with a 2 × 2 factorial design and a follow-up of one year. Employees eligible for this study are those who reported sick within 2 to 8 weeks with psychological distress based on a distress screener. Participants will be randomized to a group receiving a tailored e-Health app or usual care, as well as randomized to a group receiving a Participatory Approach (PA; conversational method) in the workplace or usual care. The PA will however only be provided in case of persistent sickness absence at 8 weeks. Measurements take place at baseline, after the e-Health intervention period (3 months), and after the PA intervention period (6 months) and 12 months. Primary outcome is lasting RTW, defined as full RTW in previous or equal work for at least four consecutive weeks. Secondary outcomes are (the severity of) stress-related symptoms, total number of sickness absence days, self-efficacy for RTW and self-reported health. A process evaluation including a realist evaluation will also be conducted. DISCUSSION: Early intervention that focuses on RTW, the cognition towards RTW despite symptoms and involves the workplace environment, plays a crucial role in managing sickness absence among employees with psychological distress. If effective, the stepped-care approach is relevant for employees, employers and society as a whole. TRIAL REGISTRATION: ISRCTN: 90663076. Registered on 5 October 2023.

The effect of the Progressive Goal Attainment Program on cognitions, perceptions, and work participation of workers with chronic health problems: study protocol for a randomized controlled trial.

BACKGROUND: Cognitions and perceptions of workers with chronic health problems, such as catastrophizing thoughts and fear-avoidance beliefs, can negatively influence work participation. The Progressive Goal Attainment Program (PGAP) is an intervention developed in Canada with the aim of decreasing limiting cognitions and perceptions and increasing work participation. The objective of this protocol article is to describe the design of a randomized controlled superiority trial to study whether PGAP is effective in decreasing limiting cognitions and perceptions and increasing workability and work participation of workers with chronic health problems in the Netherlands. METHODS: This study is a randomized controlled superiority trial with two (parallel) groups, in which workers on sick leave are randomly assigned to an intervention group (PGAP intervention) or to a waiting-list control group (care as usual). The PGAP intervention consists of a maximum of 10 weekly individual sessions provided by a trained PGAP professional in which the worker learns about staying active, planning activities, and setting goals. Participants in this risk-targeted behavioral activation intervention also learn to be more aware of their cognitions and perceptions and learn about solution-focused problem-solving skills in challenging situations. The primary outcome is the degree of catastrophizing. Secondary outcomes are other personal cognitions and perceptions (e.g., expectations regarding return to work, self-efficacy), health symptoms (e.g., fatigue, depression), work participation (e.g., sick leave status, work hours), and other work-related outcomes (e.g., workability, quality of working life). DISCUSSION: Although PGAP shows positive effects in Canada, we do not know whether this intervention is effective in the Netherlands. This study is the first randomized controlled trial to test the effect of PGAP on limiting cognitions and perceptions and on work participation of workers with chronic health problems in the Netherlands. If PGAP is effective it could be implemented in the Netherlands in order to stimulate workability and work participation of workers. TRIAL REGISTRATION: The protocol of this study is registered in the Netherlands Trial Register (NL9832) in October 2021.
