Mixed-sided individuals with neuroticism sustain more unintentional injuries in India.

Previous research has shown a positive association between unintentional injury liability and non-right-handedness (especially mixed-handedness). Research has also shown neuroticism to be one of the main predictors of unintentional injuries. In the present study we investigated the relationship of the three variables--frequency of unintentional injuries, side bias, and neuroticism. Further, the study aimed at extending the findings of previous studies establishing a relationship between non-right-handedness and unintentional injuries to a similar pattern in other domains of side bias--footedness, eyedness, and earedness. Data were collected from a large sample (N = 3474) using the side bias questionnaire, the shorter version of Maudsley's Personality Inventory, and an unintentional injury checklist. Results revealed positive correlations between the frequency of unintentional injuries and mixed-sidedness, followed by left-sidedness and right-sidedness in each of the four domains of side bias. Furthermore, an increase in the frequency of unintentional injuries was observed for mixed-sided and left-sided individuals with higher levels of neuroticism.
