The purpose of this study was to determine the impact parental divorce has on adolescent students in Senior High Schools in Ghana and the type(s) of internalizing types of behaviours that mostly affect the adolescent student. The participants comprised adolescent students from four Senior High Schools in Obuasi Municipality in the Ashanti Region of Ghana. A purposive sample of 396 students consisting of 198 males and 198 females participated in the study. The cross-sectional descriptive survey, using a questionnaire, was adopted in collecting the data. The questionnaire had a Cronbach’s alpha of 0.84. The results of the study indicated that parental divorce greatly impacted adolescent students. The negative impacts manifest in the form of internalizing behaviours in adolescent students. The result also points out that adolescent students who have experienced divorce from Christian homes demonstrated more internalizing types of behaviour than those from Muslim homes. It is recommended that counselling be given to adolescent students in schools from divorced homes and that teachers should make efforts to identify such adolescent students. Christians should encourage their wards to follow their practices to enable them to overcome their externalizing and internalizing behaviours. Finally, parents should also be sensitized to the internalizing types of behaviour in their children.
