Data were collected through a validated 57-item questionnaire. Logistic regression analyses were performed to examine predictors of seatbelt non-use across three models incorporating behavioral, demographic, and background variables. Data were analyzed using SPSS 16.</span></span></span><br> <span style="line-height:normal"><b><span style="font-size:10.0pt"><span cambria="" style="font-family:"><span style="color:#4f81bd">Findings:</span></span></span></b> <span style="font-size:10.0pt"><span cambria="" style="font-family:">Only 24% of passengers consistently used seatbelts. In the final logistic regression model, significant predictors of seatbelt non-use included perceived barriers (OR=1.08; p=0.003), low supervision (OR=1.13; p=0.04), health locus of control (OR=1.18; p=0.05), and poor law adherence (OR=2.6; p<0.001). Conversely, subjective norms (OR=0.75; p<0.001) and environmental factors (OR=0.82; p=0.02) were associated with higher seatbelt use. The model demonstrated acceptable goodness of fit (Hosmer-Lemeshow p=0.08) and good discrimination (area under the curve=0.78; 95%CI: 0.74-0.87). </span></span></span><br> <span style="line-height:normal"><b><span style="font-size:10.0pt"><span cambria="" style="font-family:"><span style="color:#4f81bd">Conclusion:</span></span></span></b> <span style="font-size:10.0pt"><span cambria="" style="font-family:">Seatbelt use among intercity bus passengers in Iran is low and externally motivated.</span></span></span> Seat Belt,Behavioral Risk Factors,Transportation Facility,Passenger, 189 194 http://hehp.daneshafarand.org/browse.php?a_code=A-10-1-108&slc_lang=en&sid=4 J.
