Aim of this study was to evaluate the effect of counseling sessions on social phobia and self- esteem among secondary school female students. Research Design for conducting this study was a quasi-experimental. Setting: this study was conducted at El-Sinbilawien governmental secondary school for girls, Dakhalia governorate, Egypt, during the School Year 2018-2019. Subjects: a purposive sample of 260 females were selected randomly and enrolled in the assessment phase. Then the counselling sessions (pre-post test) were carried out on 187 participants based on the assessment phase's result. Tools of data collection were socio-demographic data sheet, social phobia inventory (SPIN) and Rosenberg self-esteem scale (RSES). Results revealed statistically significant difference between pre and post-test mean scores of SPIN and RSES.
