Data were collected using &ldquo;The Connor-Davidson Resilience Scale (CD-RISC)&rdquo; and &ldquo;The Pintrich and De Groot&#39;s Motivated Strategies for Learning Questionnaire (MSLQ)&rdquo; in two stages of pre- and post-test and were analyzed using MANOVA and ANCOVA statistical tests, while P < 0.05 was considered significant.</span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="text-autospace:none"><span style="unicode-bidi:embed"><span calibri="" style="font-family:"><a name="_Hlk83282040"><b><span new="" roman="" style="font-family:" times="">Results</span></b></a><b><span new="" roman="" style="font-family:" times="">:</span></b><span new="" roman="" style="font-family:" times=""> In the present study, assertiveness training was effective on self-regulation and resilience building by modifying pre-test scores (P = 0.001). Stress management training was effective on self-regulation building by modifying pre-test scores (P = 0.003). However, in the variables of trust in individual instincts, negative emotion tolerance, positive acceptance of change and safe relationships, control and spiritual effects, there is a significant difference between the mean post-test score of the stress management group and control after controlling the pre-test scores, which indicates the effectiveness of stress management training on resilience building (P = 0.001). Furthermore, assertiveness and stress management training had an effect on self-regulation and resilience building (P < 0.05).</span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="text-autospace:none"><span style="unicode-bidi:embed"><span calibri="" style="font-family:"><a name="_Hlk85713844"><b><span new="" roman="" style="font-family:" times="">Conclusion</span></b></a><b><span new="" roman="" style="font-family:" times="">:</span></b><span new="" roman="" style="font-family:" times=""> Among junior high school students, assertiveness and stress management training has been effective on self-regulation and resilience building among adolescent girls. </span><b>&nbsp;</b><b><span style="font-family:"Times New Roman",serif"></span></b></span></span></span></span></span></div> School girls, Stress management, Assertiveness 43 51 http://jbrms.medilam.ac.ir/browse.php?a_code=A-10-539-2&slc_lang=en&sid=1 Fatemeh Shohani f.shohani68@yahoo.com 10031947532846007655 10031947532846007655 No Department of Psychology, Ilam Branch, Islamic Azad University of Ilam, Ilam, Iran Zeinab Mihandoost xozns2006@yahoo.com 10031947532846007656 10031947532846007656 Yes Department of Psychology, Ilam Branch, Islamic Azad University of Ilam, Ilam, Iran Sharam Mami Shahram.Mami@yahoo.com 10031947532846007657 10031947532846007657 No Department of Psychology, Ilam Branch, Islamic Azad University of Ilam, Ilam, Iran
