Abstract
The study examined emotional intelligence as a predictor of counsellors' effectiveness in Secondary Schools in Imo State. The study adopted descriptive research design of correlational type. The population was 110 Registered Guidance Counsellors in 1450 public and private schools. The sample size was 85 Guidance Counsellors selected based on two stage sampling involving simple random sampling and purposive sampling. Two instruments were used in collecting the data for the study, namely, Emotional intelligence Questionnaire (EIQ) and Counsellors' effectiveness questionnaire (CEQ). The two instruments were face validated by three experts. The internal consistencies of the instruments yielded reliability coefficient indices of 0.78 (EIQ) and 0.84 (CEQ). The research question was analysed using Pearson Product Moment Correlation while the hypothesis was tested using linear regression at 0.05 level of significance. The result indicated that emotional intelligence to a high extent predicted effectiveness of Guidance Counsellors in secondary schools among others. It was recommended among others that emotional intelligence should be considered in the hiring and training of Guidance Counsellors.
