The objective of the study was to test the influence of Attention-Deficit/Hyperactivity Disorder (ADHD) and its associated problems. The focus of the study was college students in the city of Mexico. The methodology was quantitative and survey based. Data is collected from two selected college students and sample size was 327. Correlation results shows that there is positive and significant relationship between ADHD and psychological problems. Accordingly, attention deficit is positively associated with internet addiction (r=.33, P<.05); depression (r=.29, P<.05); anxiety (r=.26, P<.05); stress (r=.41, P<.05); and social phobia (r=.27, P<.05). The other variable is hyperactivity/impulsivity which is also positively associated with internet addiction (r=.34, P<.05); depression (r=.29, P<.05); anxiety (r=.29, P<.05); stress (r=.27, P<.05); and social phobia (r=.26, P<.05). The canonical correlation results shows that attention deficit disorder is associated with dependent variables including internet addiction (Fstat=6.09, P<.05); depression (Fstat=4.78, P<.05); anxiety (Fstat=2.89, P<.05); stress (Fstat=7.92, P<.05); and social phobia (Fstat=4.94, P<.05). Similarly, hyperactivity/impulsivity is positively associated with internet addiction (Fstat=8.27, P<.05); depression (Fstat=5.30, P<.05); anxiety (Fstat=6.69, P<.05); stress (Fstat=20.61, P<.05); and social phobia (Fstat=3.51, P<.05). Overall, our results implies that ADHD is positively leading to other psychological problems among the college students and hence need suitable intervention
