2.3. Statistical analysis
Descriptive statistics and statistical analyses were performed with computerized statistical package (SPSS 17.0,
Inc., Chicago, USA) software. The internal consistency of the scale was examined using Cronbach's alpha.
Descriptive statistics were used on all variables. Differences between groups were identified with Student’s t-test and correlations were performed using Pearson coeficient. Multiple linear regression analyses were performed
utilizing perceived severity, perceived susceptibility, perceived benefits, perceived barriers and self-efficacy as
independent variables in the study group. All reported P-values are two-tailed; moreover, those P-values less than
0.05 were considered statistically significant.
