Studies have shown that the prevalence of ADHD in children is 4 to 10 percent of the population, which is common    . And it is not just restricted to childhood but 50 to 80 percent of cases are in young adults  . Reports show that at least 35 percent of adolescents with ADHD have once been expelled from school and the percentage of normal adolescents is 8 to 10 percent  . There is evidence that higher levels of self- efficacy in students increase academic motivation  . In fact, such variables are likely to be low levels of self-efficacy in adolescents with ADHD. Self-understanding is a possibility of commitment to a work program and increases health-promoting behaviors  .  in separate studies has shown that ADHD will have a negative impact on the success of social, educational and emotional development   . This research is important. The aim of this study was to compare the efficacy of students with attention deficit/hyperactivity disorder and normal students   .
2. Material and Methods
This research is a comparative study and case-control. The population consisted of all male students in second and third high school in school year 2011-2012 in Delijan city. The sample consisted of 60 boys with ADHD who were selected from among 1,200 students through clinical interviews. In addition, 60 normal students in a way that matched (based on education, father, maternal education and birth) were selected. The following tools were used to collect data: 1
- Scale of Attention Deficit/Hyperactivity Adults: The scale has 26 items. The raw scores of the scale using proper norm table are converted to T scores. T-scores above 65 are clinically meaningful and T scores above 80 in addition to the pathology of the problem and the field shows they also raised the possibility of exaggeration of symptoms. Its reliability and validity of the questionnaire manufacturers vary from 850 to 0.95 to 0.37 from 0.37 reported (Conner et al., 1999). Internal consistency reliability of the scale, the Cronbach’s alpha coefficient (r = 0.81) and its content validity was confirmed through three specialty children.
- Self-Efficacy Scale: Scale is self-adolescents 24 article by Morris (2001) has been made. Subjects with a five-point scale (very bad to very good) response, this self-efficacy questionnaire with three subscales academic, social and emotional measures and alpha has been reported that 0.88. The correlation coefficient between this questionnaire and children’s questionnaire (0.40) is obtained (0.01
Before using multivariate analysis of variance to comply assumptions of parametric tests, the test box and cauliflower were used. Based on the test box was not significant for any of the variables, the condition of homogeneity of variance matrices/covariance is properly observed (P = 0.82, F-0.63, BOX = 8.13) (Table 1). According to Levene test and non-significant for all variables, the condition of equality between group variances was not met. Wilks Lambda test results showed that the combined effect of group self- efficacy component of academic, social and emotional is significant (0.001 > P, F = 3.26, Wilks Lambda = 0.106). The results showed that at least one of the studied variables there are significant differences between the two study groups.
Multivariate analysis showed that the mean scores for self-education (F = 112.99), social self-efficacy (F = 699.13) and emotional self-efficacy (F = 510.67) was significantly higher in normal school students ADHD (P > 0.001) (Table 2).
This study compared the efficacy of students with attention deficit/hyperactivity disorder and normal students. These findings are consistent with other research findings (for example, Pajars, 2000; Parry et al., 2002; Foreign et al., 2003; Johnson et al., 2008). Efficacy as an institution, is exercising control over the individual  . However, various studies have shown that teens with ADHD are facing academic difficulties  .

In terms of individuals and peers, teens with ADHD are more domineering and annoying; in fact, these young people ensure homogeneous react with intolerance and avoidance  . Rejection in class leads to social isolation, rejection by peers and ultimately to reduce the social efficacy. Finally we can say that emotional self-perception of their ability can control and manage feelings and negative thoughts  . They cannot get their excitement for the benefit of adjusting for other thrill and excitement, and this is what is called self-control. In general, these teenagers are lacking in emotional self- control and self-efficacy.
