The adolescence witnesses a rapid physical, psychological and emotional development which is known as a period of storm and stress (Arnett, 1999; Scales, Benson, & Roehlkepartain, 2001). The puberty, sexuality, self-image, self-esteem, eating problems, egocentrism, moral growth, social identity development, relations with parents, siblings and peers, are only few of the aspects of the development at this stage, against which the adolescents respond through various behaviours. Such behaviours may be inappropriate, unsuitable, and wrong or may even harm the health of the adolescents.
