Abstract
The study investigated neuroticism and insecurity as predictors of school adjustment among secondary school students in Abia State. Two research questions guided the study and two null hypotheses were tested at 0.05 level of significance. The study adopted a correlation research design. A total of 600 respondents drawn through multi stage sampling technique from a population of 2500 senior secondary class two (SS2) students in the four Education Zones of Abia State were used for the study. The sample constituted 24% of the entire population. Three research instruments were developed by the researcher and were used for data collection namely “Neuroticism Personality Trait Assessment Questionnaire (NPTAQ), Students Insecurity Questionnaire (SIQ) and School Adjustment Questionnaire (SAQ)”. The SPTAQ consisted of ten (10) questionnaire items. The SIQ used in this study consisted ten (10) questionnaire items and the NPTAQ consisted of 10 questionnaire items. Each of the instruments was structured on a four- point scale ranging from Very High Extent (VHE) = 4 points, High Extent (HE) = 3 points, Low Extent (LE) = 2 points, Very Low Extent (VLE) = 1 point. The three instruments were face validated by three experts in Psychology and Counselling and Research, Measurement and Evaluation respectively from Michael Okpara University of Agriculture, Umudike. The internal consistency reliability was determined using Cronbach Alpha Procedure. The instruments had reliability coefficients of .83 for the NPTAQ, .84 for the SIQ, and .82 for the NPTAQ respectively. The instruments were administered to the students using direct delivery approach through the help of three (3) research assistants. All the copies of the questionnaires were returned. Pearson Product Moment Correlation Coefficient (Pearson r) was used to answer the research questions, while linear regression analysis was used to test the null hypotheses at 0.05 level of significance. The major findings of the study were that Neuroticism negatively predicted 52.4% of the school adjustment among secondary school students and neuroticism significantly and negatively predicted school adjustment among secondary school students in Abia State. Insecurity was a significant predictor of school adjustment among secondary school students as it negatively predicted 88.9% of the variance observed in the school adjustment among secondary school students’ in Abia State.
