Brief summary

Firefighters are routinely exposed to potentially traumatic events, making them vulnerable to debilitating mental health problems. Consequently, promoting well-being and the ability to respond effectively and safely to work demands are vital. The FIRE is an innovative mindfulness, Acceptance and Commitment Therapy, and compassion-based manualized intervention encompassing eight weekly group sessions delivered at Fire Stations. A preliminary version of this program will be refined based on qualitative inputs from structured interviews with firefighters and emergency/civil protection sector stakeholders. The FIRE feasibility dimensions of adaptation, acceptability, implementation, practicality, integration, and limited efficacy will be evaluated in a two-arm, 1:1, non-blinded randomised controlled trial. The extent to which the FIRE contributes to the promotion of well-being and the decrease of psychopathological symptoms, and the causal theory underlying FIRE, will be explored through an examination of potential mechanisms of change.

Detailed description

The FIRE is an innovative mindfulness, Acceptance and Commitment Therapy, and compassion-based manualised intervention, encompassing 8-weekly group sessions delivered at Fire Stations. The FIRE implementation will occur outside the Charlie phase (fire critical season, from May to October), controlling for the potential seasonality impact on results. Two clinical psychologists with mindfulness, ACT, and compassion training will facilitate the FIRE sessions. Weekly gentle reminders will be sent to motivate participants to practice the between-sessions exercises. The current project aims to conduct a feasibility study, including the dimensions of adaptation, acceptability, implementation, practicality, integration, and limited efficacy. Regarding limited efficacy, it is hypothesised that participants in the experimental group (EG-FIRE) will reveal significant decreases in firefighters' psychopathological symptoms (depression, anxiety, PTSD) and will present higher levels of well-being, feelings of belonging, acceptance, and feelings of warmth from colleagues, and attention when compared to participants in the waiting-list control group (CG-WL). It is also hypothesised that these improvements will persist over a 3-month follow-up period. The ANEPC will invite Fire Stations in the centre region of Portugal to participate. The FIRE will be presented at each Fire Station enrolled in the study during an informative session, and a leaflet will also be distributed. Interested firefighters will be asked to register, assess eligibility, and give informed consent. Consenting participants will be randomly allocated to: a) experimental group-EG-FIRE receiving the intervention; b) wait-list control group-WL-CG. All ethical requirements for research with humans will be guaranteed. Participants will complete online standardised self-report measures at pre-intervention (M0), post-intervention (M1), and 3-month follow-up (M2). At M1, the EG-FIRE will complete a feasibility criteria questionnaire. Limited efficacy will be assessed using Intention-to-Treat and per-protocol analyses. Two-way mixed ANOVAs and MANOVAs will be computed on the study outcomes, with Group (EG-FIRE, WL-CG) as the between-subject variable and Time (M0, M1) as the within-subject factor. Repeated ANOVAs and MANOVAS with Time (M1, M2) as the within-subject factor will be computed to investigate changes in outcomes from M1 to M2 and at the 3-month follow-up in the EG-FIRE. Effect sizes will be analysed. To limit attrition rates, risks, and barriers to the FIRE implementation (interference with firefighters' assignments), it will be proposed that sessions be scheduled to avoid conflicts with participants' work shifts, held at the Fire Station (to avoid participants' burden). It will be negotiated to include the FIRE sessions in the national training hours plan for EG-FIRE participants. To ensure the program's rigorous implementation, weekly meetings will be held with the project supervisors. The FIRE is expected to be a feasible program that will advance, disseminate, and facilitate knowledge transfer, providing scientific evidence to inform mental health practices for the emergency and civil protection sectors. It is expected to promote well-being, feelings of connectedness, belonging, warmth, acceptance, and attention, and decrease firefighters' psychopathological symptoms. Mental health benefits are expected to result from improvements in mindfulness, psychological flexibility, and compassion skills, and from decreases in rumination, and to be sustained over a 3-month follow-up. Two self-report measures adapted to the firefighters' setting will be available, contributing to further investigate psychological aspects in this population.

Interventions

BEHAVIORALFIRE

The FIRE will include 8-weekly group sessions (10-15 participants per group; 90-minutes duration) delivered at Fire Stations. The FIRE implementation will occur outside the charlie phase (fire critical season, from May to October), controlling for the potential seasonality impact on results. Two clinical psychologists with mindfulness, ACT and compassion training will facilitate the FIRE sessions. Weekly gentle reminders will be sent to motivating participants to practice the between-sessions exercises.

Intervention model description

Fire Stations in the centre region of Portugal will be invited to participate by the National Emergency and Civil Protection Authority (ANEPC). Consenting Fire Stations will be randomly allocated (www.random.org) to: a) experimental group-EG-FIRE receiving the intervention; b) wait-list control group-WL-CG. FIRE will be presented to the EG-FIRE fire stations participating in the study at an information event, and a brochure will also be distributed. Interested firefighters will be asked to register, assess eligibility, and provide informed consent.

Design outcomes

Primary

MeasureTime frameDescription
Well-beingBaseline, 8 weeks and 3-month follow-upMeasured by the World Health Organization Well-Being Index 5 (WHO-5). The total raw score, ranging from 0 to 25, is multiplied by 4 to give the final score, with 0 representing the worst imaginable well-being and 100 representing the best imaginable well-being.

Secondary

MeasureTime frameDescription
DepressionBaseline, 8 weeks and 3-month follow-upMeasured with the depression subscale of the Patient Health Questionnaire 4 (PHQ-4). The subscale scores range between 0 and 6. Scores equal or higher than 3 are a reasonable cut-off point for detecting possible cases of depression.
AnxietyBaseline, 8 weeks and 3-month follow-upMeasured with the anxiety subscale of the Patient Health Questionnaire-4 (PHQ-4). The subscale scores range between 0 and 6. Scores equal to or higher than 3 are a reasonable cut-off point for detecting possible cases of anxiety.
PTSDBaseline, 8 weeks and 3-month follow-upMeasured with the PTSD Checklist-5. The total score ranges from 0 to 80, with higher scores indicating greater severity of post-traumatic stress disorder symptoms.
AttentionBaseline and 8 weeksMeasured with the Toulose Piéron Cancellation Test. Performance is assessed based on the number of correctly cancelled stimuli, errors of omission and commission, and indices of attention and concentration, with higher scores indicating better attentional performance.
MindfulnessBaseline, 8 weeks and 3-month follow-upMeasured with the Five-Facet Mindfulness Questionnaire (FFMQ; 18-item version). The total score for this scale ranges from 18 to 90, with higher scores indicating greater mindfulness skills.
CompassionBaseline, 8 weeks and 3-month follow-upMeasured with the Self-Compassion Scale - short form (SCS-SF). The total score for this scale ranges from 12 to 60, with higher scores indicating greater self-compassion.
Psychological FlexibilityBaseline, 8 weeks and 3-month follow-upMeasured with the Psy-Flex. The total score for this scale ranges from 5 to 30, with higher scores indicating greater psychological flexibility.
Social SafenessBaseline, 8 weeks and 3-month follow-upMeasured with the Social Safeness and Pleasure Scale - Firefighters (SSPS-F). The total score ranges from 11 to 55, with higher scores indicating greater perceived social safeness and pleasure.
