| Purpose: The aim of the present study was to compare personality characteris cs in injured motorcyclists
and uninjured motorcyclists.

pa ents along with 91 control pa ents admi ed to Shohada and Imam Reza university hospitals as the two
referral specialty centers in East Azarbyjan Province of Iran in 2013. The Persian version of the motorcycle
Riding behavior ques onnaire (MRBQ) was used to assess riding behavior. Also, Millon Clinical Mul axial
Inventory-III was used to access personality disorders and psychiatric syndromes. Mul variate binary
logis c regression was used as the main analysis method to es mate the adjusted odds ra os of subscales
of Millon-III and risky behavior scales. The sta s cal analysis was conducted using Stata version 11
sta s cal so ware package.
Results: Mean/median scores of the personality subscales of schizoid, alienated, obsessive-compulsive,
self-abusing, schizotypal, paranoid, post-trauma c stress, thought disorders, major depression, delusional
disorder in the injured group were higher than in the control group (P<0.05). However, histrionic
personality disorder was observed less in the injured group than the control group (P <0.01). According
to the logis c regression models obsessive-compulsive and paranoid disorders were considered to be risk
factors in motorcycle injuries.
Conclusion: According to the results of this study, obsessive-compulsive personality was a risk factor for
motorcycle traffi c injuries. |
