The purpose of this study was to compare self-efficacy and self-regulation between the students with SRB and students with NSRB, and the relationship of these variables to academic performance. Using a random stratified sampling technique 60 girl students who had school refusal behavior (SRB) and 60 of students without SRB were selected from 8 high schools. The general self efficacy scale (GSE; Schwarzer & Jerusalem, 1995), the Kearney, Cook, and Chapman, 2007's school refusal criterions; self-regulation inventory (Kanlapan & Velasco, 2009), and the student's current academic performance scores as a measure of academic performance were used for collecting the data. Independent t-Test showed that there are significant differences between self-efficacy, self-regulation and academic performance among two groups (p<0.05). Finally results showed that self-efficacy and self-regulation have simple and multiple significant correlation with academic performance in two groups (p<%5).
