Department of Guidance and Counselling University of Calabar, Calabar Nigeria Abstract The study investigated cyber harassment, cyber denigration and social adjustment among secondary school students in Calabar Education Zone of Cross River State, Nigeria. To achieve the purpose of this study which was to find out the influence of cyber harassment and cyber denigration on social adjustment of secondary school 1 (SS1) students, two hypotheses were formulated. The ex-post facto research design was adopted for this study. The population of the study comprised 8,829 public secondary school students. Purposive sampling technique was used to select 530 students for the study. Cyber bullying Assessment Questionnaire (CAQ), designed by the researchers was used to elicit responses for the study. It was constructed on a four-point Likert scale of strongly agreed, agreed, disagreed and strongly disagreed. The reliability coefficient of the instrument which was found using Cronbach Alpha Reliability method was between 0.71 and 0.79. One-way Analysis of Variance (ANOVA) was used as the statistical tool for data analysis. The two hypotheses were tested at 0.05 level of significance. The findings of the study revealed that cyber harassment and cyber denigration have negative influence on the social adjustment of secondary school students in Calabar Education Zone of Cross River State, Nigeria. It was therefore recommended that government should formulate policies that would effectively assist in the eradication of harmful online communications. Social Welfare Agencies should device means of implementing and consolidating effective cyber frame works that will protect students from being harassed, and Guidance Counsellors should counsel students against cyber-crimes.
