VL is effective in significantly improving all aspects of HPL, namely nutrition, physical activity, life appreciation, social support, health responsibility, and stress management among single-parent adolescent girls. Therefore, healthcare authorities are recommended to use VL to promote health and prevent illnesses among vulnerable adolescents. Future studies are recommended to compare the effects of face-to-face and virtual logotherapy in different vulnerable populations such as individuals with specific diseases, addicts, and homeless individuals, as well as healthy individuals.
