High levels of loneliness among construction workers in Western Australia is the most pertinent factor driving suicidal thoughts and highlights a need to strengthen social connection, according to a new study.
Published in Journal of Affective Disorders the research was led by Dr Michael Kyron from the School of Psychological Science at The University of Western Australia, and Dr Joseph Carpini, from UWA's Business School, through the WA Suicide Prevention and Resilience Research Centre, with industry partner MATES in Construction WA.
"The study found 11 per cent of WA construction workers indicated experiencing suicidal thoughts in the 12 months prior to being surveyed, while 4.7 reported plans and 1.1 per cent attempts," Dr Kyron said.
Researchers identified people in the LGBTQAI+ community, those with a recent relationship breakdown, apprentices and individuals working in a FIFO/DIDO (drive-in drive-out) arrangement as the most vulnerable groups.
"The most critical risk factor was loneliness followed by workplace bullying, work-family conflict and substance abuse," Dr Kyron said.
"Experiencing multiple risk factors at the same time can significantly increase vulnerability."
The findings call for evidence-based training, such as mental health first aid, which can help workers recognise early signs of distress and confidently support at-risk colleagues.
"Targeted suicide-prevention training for selected 'gatekeepers' can provide specialised skills for intervention," Dr Carpini said.
"Workers should be encouraged to regularly check in with peers, challenge stigma and seek help early through employee assistance programs, general practitioners or mental health professionals."
The study also found workplaces should adopt robust anti-bullying policies, clear reporting processes and timely investigations to ensure psychological safety.
"Regular toolbox meetings, mentoring programs and peer-support initiatives can enhance social cohesion, especially for apprentices who are at increased risk," Dr Carpini said.
"Addressing psychosocial hazards is now a legal responsibility, requiring employers to manage mental health risks with the same rigour as physical safety."
Researchers concluded industry-wide codes of conduct could set consistent expectations around behaviour, diversity and inclusion, and reduce bullying and other harmful practices.
"Encouraging open, stigma-free conversations about wellbeing — including safe sharing of personal experiences — can build healthier help-seeking pathways," Dr Kyron said.
