As part of a suite of early intervention training and support services, Mates in Construction (MATES) provide two general awareness programs to promote mental health and suicide awareness and encourage help-offering and help-seeking in construction workers. General awareness training (GAT) is a one-hour session delivered to all construction workers on large to medium worksites, while MATES awareness training (MAT) maintains similar content but is of shorter duration and delivered informally to small workplaces. This study aimed to compare the effectiveness of the two programs using a before, after and follow-up design. Construction workers undertaking MAT or GAT training completed a short survey before and after their training and again at follow-up. Linear mixed-effect modelling indicated that GAT and MAT training provided similar results in improving suicide awareness and help-seeking intentions. Some variables showed a significant increase from pre-intervention to the three-month follow-up, indicating the long-term impact of some aspects of the training. The findings demonstrating the effectiveness of MAT training have important implications for MATES, as the training can be delivered to much smaller workplaces, making the program more widely available to the construction industry.

The Mates in Construction (MATES) program was developed to address the issue of high suicide rates among males in the Australian construction industry. The program delivers early intervention training and support to construction workers. This mixed-methods study aimed to (1) examine the effectiveness of training for MATES connectors and (2) examine the barriers, motivations and pathways to help-seeking and help-offering for both MATES connectors and clients. A total of 104 volunteers completed a short survey before and after connector training sessions. Quantitative data analysis showed significant increases in connectors’ self-reported suicide awareness, and willingness to offer help to workmates and seek help themselves. For the qualitative component, 27 connectors and clients participated in focus groups and individual interviews. Thematic analysis identified six themes from the connectors’ data: awareness, skills and confidence; removing stigma; making a difference; simplicity of the model; understanding the industry; and visibility, camaraderie and passion. For clients, three key themes emerged: barriers and pathways to help-seeking; speaking the same language; and flow-on effects. The results provide evidence for the effectiveness of connector training and indicate that MATES’s peer support model is enabling workers to overcome traditional barriers and attitudes to seeking and offering help.

There is evidence indicating that traditionally male-dominated occupations are associated with greater risk of suicide. In Australia, MATES in Construction was developed as an occupational health initiative to prevent suicides in the industry. The program has recently been applied to the energy industry; however, little is known regarding exposure to suicide and suicide prevention interventions in this sector. The study aimed to examine the effectiveness of MATES in Energy general awareness training (GAT), and estimate the prevalence of recent suicidal ideation and exposure to suicidal behaviors in workers. A before and after design was used to examine the effectiveness of GAT training. Data were collected from 4887 participants undertaking GAT training at energy sites across Queensland, Australia. In total, 2% (97) of participants reported recent suicidal thoughts, 65% of participants reported they had known someone who had attempted suicide, and 69% had known someone who died by suicide. Significant improvements were found on all suicide literacy items after GAT training. Younger people were more likely to be positively affected by the intervention. The results indicate that the MATES in Energy program is successfully transitioning from the construction industry, and offers the first empirically supported suicide intervention tailored to the energy sector.

Status obtained via dominance is a phylogenetically ancient feature of human social systems. Yet empirical evidence that men’s secondary sexual traits reliably predict success in intra-sexual contests has been hard to demonstrate. The present work provides the first test of whether masculine craniofacial structures in men predicts aggressiveness in contest competition and whether people accurately assess such aggressiveness from masculine facial cues. After placing 32,447 facial landmarks on the facial stimuli of 457 male fighters, multivariate geometric morphometric analyses extracted 142 distinct facial metrics and revealed that men with better developed masculine facial traits (e.g., large jaw, large browridge, deep-set eyes) attempted more strikes and successfully struck their opponents, including targeting the face. When rating the facial stimuli of these male fighters, participants (N = 500) used men’s masculine facial traits to accurately predict these same components of aggressiveness, including targeting the face. These findings remained robust after accounting for the fighter’s age, total fights, weight division, height, fight duration, and their opponent’s striking frequency. Our findings provide the first evidence that humans accurately forecast men’s agonistic behavior from variation in facial morphology, suggesting perceptual systems have evolved to perceive physical formidability among contemporaries and competitors.
