The study examined the Parental Attitude towards Adolescent Sexual Behaviour in Akoko Edo and Estako--West Local Government Areas, Edo State, Nigeria. A descriptive survey research design was adopted for the study. The sample size of 600 parents--350 (58.39%) fathers and 250 (41.7%) mothers--was purposively selected from the two local government areas for the study. This was complemented with focus group discussion conducted with 20 (twenty) parents currently teaching in 8 secondary schools in the local government area of the study. Four research hypotheses were generated based on attitudinal topical areas. A self-developed questionnaire and validated for its reliability at R = 0.86 was used to elicit responses from the participants. Data collected were coded and analyzed using descriptive statistics. The study revealed that some the four variables were significant. Based on the findings of the study, parents should be groomed on the importance of having interest in the adolescent sexuality issue. This should be done through mass media, conferences and workshops. Government should make the course on adolescent reproductive health compulsory in all schools. Enlightenment campaign by NGO by other stake holders should be encouraged by the government--at both federal and state level.
