The current study is one of the experimental studies that seeks to test the relationship between two independent variables: One of which is cognitive-behavioral therapy, and the other is a dependent variable (i.e. the addiction of university youth to social media). The experimental design provides an opportunity for an accurate measurement of hypotheses. The main objective of the study is determined as follows: Testing the effectiveness of cognitive-behavioral therapy in alleviating social media addiction among university youth groups. The following sub-objectives emerge from this major objective: 1. determining the effectiveness of cognitive-behavioral therapy in alleviating low social media addiction among university youth groups; 2. determining the effectiveness of cognitive-behavioral therapy in alleviating mean social media addiction among university youth groups; 3. determining the effectiveness of cognitive-behavioral therapy in alleviating high social media addiction among university youth groups. The researcher used a scale of university youth social media addiction that the researcher prepared, and the results of the study show no statistically noticeable differences at the level of significance (0.05) between the mean ranks of the members in the control and experimental groups in the pre-measurement of the level of social media addiction.
