The sample consisted of 24 female adolescents with complicated grief symptoms who had lost a parent to COVID-19 in 2022. Participants were purposefully selected from girls&rsquo; high schools in Bandar Abbas, Hormozgan Province, Iran, and after matching for age and gender, were randomly assigned to an experimental group (n = 12) and a control group (n = 12). The experimental group received eight sessions of supportive psychological intervention based on spiritual therapy, while the control group received no intervention. Data were collected at pretest, posttest, and three-month follow-up using the Spiritual Happiness Questionnaire (Afaroz, 2016) and the Resilience Scale (Connor & Davidson, 1984). Repeated measures ANOVA was used for data analysis.<br> <b>Results</b>: The results indicated a significant increase in mean scores of spiritual happiness and resilience in the experimental group at the posttest and follow-up stages compared to the pretest (p < 0.05). These improvements were maintained at the three-month follow-up, while no significant changes were observed in the control group.<br> <b>Conclusions</b>: Supportive psychological interventions based on spiritual therapy are effective in enhancing spiritual happiness and resilience among adolescents who have experienced parental loss due to COVID-19. These findings highlight the importance of incorporating spiritually oriented psychological interventions into mental health services for bereaved adolescents.</span></span></span></span></div> Supportive interventions, Spiritual therapy, Resilience, COVID-19, Spiritual happiness 0 0 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-735-1&slc_lang=en&sid=1 Mojdeh Khademali moj.khademali@gmail.com 0009-0009-8488-0415 No PhD student in educational psychology Kish International Campus, Tehran University, Tehran, Iran Gholamali Afrooz afrooz@ut.ac.ir 0000-0003-2386-3223 Yes Distinguished professor of Tehran University, Tehran, Iran Mansoureh Hajhosseini hajhosseini@ut.ac.ir 0000-0001-6937-1609 No Associate Professor, Department of Educational Psychology and Counseling, University of Tehran, Tehran, Iran Zahra Naghsh z.naghsh@ut.ac.ir 0000-0001-6065-7838 No Associate Professor, Department of Educational Psychology and Counseling, University of Tehran, Tehran, Iran
