The probably most frequently cited model in sport injury prediction from a psychological perspective is Williams and Andersen's (1998) “stress injury model”. In the model it is suggested three categories of psychological factors, i.e. personality, history of stressors and coping will influence the athletes’ response to a potentially stressful situation. Most research attention the last 10 years has focused on the category history of stressors. This category includes different types of stressors such as negative life event stress, positive life event stress, hassle and previous injuries. Given that history of stressors has gained most attention in sport injury research the aim of the study was to, in meta-analysis, investigate the joint as well as separate effects of published studies aimed to investigate history of stressors impact on injury occurrence. The literature review resulted in 49 included articles. Of these 49 articles, 36 provided sufficient information for calculation for an r to z-transformation. In the total sample of selected studies, 67 different effect sizes could be calculated. The overall correlation effect size for the relationship between Stressors and injury occurrence were .129 (p<.001), 95 % CI (.096,-.161) using a random effect model. The results indicated heterogeneity between studies (Q = 214.41, df = 66, p < .001). Moreover, the results showed that negative life event stress (r = .184) and previous injuries (r = .225) displayed the strongest correlation with injury occurrence while positive life event stress showed the weakest (r = .023). Last, the result from a meta-regression confirmed that high methodological quality was related to higher correlational effects (β = .018 (.005), p < .001, 95 % CI = .009 - .03). Even if the correlational coefficient only showed a low to moderate overall effect it is suggested that stressors have an important impact on injury risk. This line of argument is for example supported by the calculated fail-and safe number indicating that 3,196 studies with zero effect results would be necessary to decrease the effect to zero. Given that stress seems to influence injury risk athletes are recommended to take part in life style interventions (e.g. mindfulness), to develop effective strategies for decrease their stress levels.
