The study method was a quasi-experimental pretest-posttest with a control group. The statistical population of the present study included all female high school students in Bushehr (Iran) in 2021. The research sample included 30 students selected by the accessible sampling method and randomly assigned to experimental and control groups. The Social Adjustment Scale by Kim (1999) and School Engagement Scale by Wang et al. (2011) were used to collect data. Group hope training based on Snyder&rsquo;s theory was performed in 9 sessions in the experimental group. The control group did not receive any intervention during this period. The results exhibited that group hope training based on Snyder&rsquo;s theory significantly increased the components of academic engagement (i.e., behavioral, emotional, and cognitive) and social adjustment in the experimental group. Overall, the research findings support the effectiveness of educational programs based on positive psychology on learners&rsquo; motivational and emotional outputs.</span></span></span></span></span></div> Group hope training, academic engagement, social adjustment, high school students 256 266 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-497-1&slc_lang=en&sid=1 Ali mohammad Ahmadi Gharacheh علی محمد احمدی قراچه amag2004@gmail.com 10031947532846006022 10031947532846006022 Yes Assistant Professor, Department of Psychology and Educational Sciences, Payame Noor University (PNU),Tehran, Iran استادیار گروه روانشناسی و علوم تربیتی، دانشگاه پیام نور، تهران، ایران Salimeh Rava سلیمه روا salimeh.rava@yahoo.com 10031947532846006023 10031947532846006023 No Department of Educational Administration, Boushehr Branch, Islamic Azad University, Boushehr, Iran گروه مدیریت آموزشی، واحد بوشهر، دانشگاه آزاد اسلامی، بوشهر، ایران Ladan Khodadadi لادن خدادادی ladan_khodadadi@yahoo.com 10031947532846006024 10031947532846006024 No Department of Clinical Psychology, Boushehr Branch, Payame Noor University, Boushehr, Iran گروه روان شناسی بالینی، واحد بوشهر، دانشگاه پیام نور، بوشهر، ایران Khalil Nabavi خلیل نبوی khalil.nabavi.43@gmail.com 10031947532846006025 10031947532846006025 No Department of General Psychology, Asaluyeh International Branch, Payame Noor University, Asaluyeh, Iran گروه روان شناسی عمومی، واحد بین الملل عسلویه، دانشگاه پیام نور، عسلویه، ایران Roya Hayati nia رویا حیاتی نیا royahayatiii@gmail.com 10031947532846006026 10031947532846006026 No Department of Psychology, Boushehr Branch, Islamic Azad University, Boushehr, Iran گروه روانشناسی، واحد بوشهر، دانشگاه آزاد اسلامی، بوشهر، ایران Mahsoom Ranjbar Bastaki معصوم رنجبر بستکی mahsoomranjbar.bastaki@gmail.com 10031947532846006027 10031947532846006027 No Department of Psychology, Bandar Abbas Branch, Islamic Azad University, Bandar Abbas, Iran گروه روانشناسی، واحد بندرعباس، دانشگاه آزاد اسلامی، بندرعباس، ایران
