An Examination of the Extent of the Impact of Bibliotherapy on Increasing Self-Concept in Adolescent Girls Aged 11-16 Years Who Are Members of Public Libraries in Khorramabad

This is a research study examining the effect of bibliotherapy on positive self-concept in adolescent girls aged 11 to 16 who are members of public libraries in Khorramabad. The research used a quasi-experimental design with a pretest-posttest control group approach. The study population consisted of all girls aged 11 to 16 registered at Khorramabad's public libraries. From among library visitors, 50 adolescent girls who scored one standard deviation below the mean on Rogers' self-concept questionnaire were selected as the sample. The study investigates whether guided reading interventions can improve self-perception in this demographic.
