About this trial

Since May 2024, New Caledonia has been experiencing a period of crisis. The organisation of the work of military personnel on the ground has been heavily impacted, with longer working hours, shorter rest periods and increased stress levels (uncertainty about the situation, lack of visibility, etc.).

Prolonged exposure to stress is accompanied by neuronal damage (Ramdani et al., 2024) and operational fatigue, a mindset that results from reversible neuronal damage and appears to be distinct from exhaustion. The aim of this study is to assess the impact of the crisis on the level of operational fatigue. In addition, identifying the organisational and human factors (Jaspers et al., 2024) that may have been protective against operational fatigue could help to optimise the way in which these factors are taken into account in the event of future crises, in order to promote resilience.

Trial outcomes

Primary outcomes

1

Assessing operational wear and tear linked to the crisis

Difference in the Burn-out Assesment Tool (Schaufeli et al., 2019) questionnaire score between exposed and control groups. This questionnaire consists of 23 items, each scored from 1 to 5. The sum of the scores for each item is then divided by 23 to give a final score of between 1 and 5. Subjects can then be classified as green (score \< 2.59), orange (2.59 to 3.02) and red (score \>3.02). The questionnaire contains sub-scores for 'exhaustion', 'mental distance', 'cognitive impairment', 'emotional impairment', 'psychological complaints' and 'psychosomatic complaints'.

Time frame
the questionnaire will be completed by the military in April 2025, i.e. 23 months after the start of the crisis for the exposed group

Secondary outcomes

1

Assessing the impact of the crisis on Burn-out Assesment Tool sub-scores

Comparison of variations in Burn-out Assesment Tool sub-scores (Schaufeli et al., 2020) between the 'exposed' and 'unexposed' groups and the first and second questionnaire two month later. This questionnaire consists of 23 items, each scored from 1 to 5. The sum of the scores for each item is then divided by 23 to give a final score of between 1 and 5. Subjects can then be classified as green (score \< 2.59), orange (2.59 to 3.02) and red (score \>3.02). The questionnaire contains sub-scores for 'exhaustion', 'mental distance', 'cognitive impairment', 'emotional impairment', 'psychological complaints' and 'psychosomatic complaints'.

Time frame
Military personnel will complete the questionnaires in April 2025 and June 2025, i.e. there will be a two-month gap between the two sessions.
2

Assessing the benefits of raising awareness of organisational and human factors on operational wear and tear

Comparison of variations of the scores of the Burn-out Assesment Tool between the group sensitised to organisational and human factors and the group not sensitised to organisational and human factor on the first and second questionnaires. This questionnaire consists of 23 items, each scored from 1 to 5. The sum of the scores for each item is then divided by 23 to give a final score of between 1 and 5. Subjects can then be classified as green (score \< 2.59), orange (2.59 to 3.02) and red (score \>3.02). The questionnaire contains sub-scores for 'exhaustion', 'mental distance', 'cognitive impairment', 'emotional impairment', 'psychological complaints' and 'psychosomatic complaints'.

Time frame
Military personnel will complete the questionnaires in April 2025 and June 2025, i.e. there will be a two-month gap between the two sessions.
3

Determining the protective and vulnerability factors (such as Psychosocial Risks) to operational wear and tear

Search for correlations between scores on the Copenhagen Psychosocial Questionnaire (Kristensen et al., 2005) and Burn-out Assesment Tool scores. Burn-out Assesment Tool questionnaire consists of 23 items, each scored from 1 to 5. The sum of the scores for each item is then divided by 23 to give a final score of between 1 and 5. Subjects can then be classified as green (score \< 2.59), orange (2.59 to 3.02) and red (score \>3.02). The questionnaire contains sub-scores for 'exhaustion', 'mental distance', 'cognitive impairment', 'emotional impairment', 'psychological complaints' and 'psychosomatic complaints'. The Copenhagen Psychosocial Questionnaire consists of 22 items, each scored from 1 to 5. The sum of the scores for each item is then divided by 22 to give a final score of between 1 and 5. 1 is the best outcome, 5 is the worth outcome.

Time frame
Military personnel will complete the questionnaires in April 2025
