Feasibility of Implementing the Internet-Delivered Stress Recovery Intervention FOREST for Healthcare Staff in a Real-World Healthcare Setting

The aim of the study is to assess the feasibility of implementing the internet-delivered stress recovery intervention FOREST for healthcare staff in a real-world healthcare setting and to obtain preliminary estimates of changes in stress recovery and mental health outcomes.

The feasibility of implementing the evidence-based, internet-delivered stress recovery intervention FOREST for healthcare staff in a real-world healthcare setting will be evaluated using a single-arm pre-post study design. The study aims to assess the feasibility of implementing the intervention within a hospital setting and to obtain preliminary estimates of changes in stress recovery and mental health outcomes to inform broader implementation across healthcare settings. Information about the intervention and the study will be disseminated within participating healthcare settings. Interested healthcare staff will complete an online eligibility screening. Individuals who meet the inclusion criteria will be invited to provide informed consent and complete the baseline assessment before being enrolled in and granted access to the FOREST intervention.

The FOREST intervention consists of six sessions (Introduction, Psychological Detachment, Distancing, Mastery, Control, and Keeping the Change Alive) delivered over a four-week period. Each session includes psychoeducational content presented through text and video materials, as well as practical stress recovery exercises. Participants will also have access to support from a trained psychologist on demand throughout the intervention.

Assessments will be conducted at baseline, immediately after the four-week intervention, and at a 12-week follow-up after baseline. The study's primary outcomes will assess implementation at the individual level, guided by Proctor et al.'s Implementation Outcomes Framework to evaluate acceptability and appropriateness, alongside intervention uptake (initiation), and complemented by feasibility and process indicators capturing reach, recruitment, engagement, and retention. Secondary outcomes will provide preliminary estimates of changes in stress recovery and other mental health outcomes.

Inclusion Criteria:

• being at least 18 years old
• working in a healthcare setting;
• understanding Lithuanian;
• living in Lithuania;
• having access to an internet-enabled device.

Exclusion Criteria: No additional exclusion criteria will be applied in order to maximize inclusiveness and reflect real-world implementation.
