The purpose of this study was to determine the influence of parental bonding on emotional stability of undergraduate students of Psychology and Sociology Departments of Nasarawa State University Keffi. The research adopted a cross sectional survey design. Purposive and simple random sampling was used to select a sample of 100 participants from the population of undergraduate of Psychology and Sociology Departments of Nasarawa State University Keffi. Data was collected via the administration of self-report questionnaire consisting of Modified Parental Bonding Instrument (MPBI) used to measure parental bonding and South African Personality Inventory (SAPI) used to measure emotional stability. Pearson correlation coefficient and independent sample t-test were used to test four research hypotheses at 0.05 significant level. The results showed that there is significant negative relationship between parental overprotection and emotional stability (r=-0.261, p<0.05). There is an insignificant positive relationship between parental care and emotional stability (r=0.161, p>0.05). Parental overprotection and parental care have no significant joint influence on emotional stability (R2 = .32; F (4, 74) = 2.04; p >0.05). Male students were found to be more emotionally stable than their female counterparts (t(98)= 2.77, P<.01). The study recommends that parents should practice positive parenting methods such as being less overprotective towards their wards as this reflects in the child’s emotional stability.
