This study investigated the predictive influence of personality factors, extraversion and
neuroticism, on life satisfaction judgements of educated adults in different age categories.
Employing a sample of 544 participants of educated adults in the age cohorts of 20 – 39
years (male = 75, female = 201), 40 – 59 years (male = 63. female = 116), and 60+ years
(male = 49, female = 40), selected through a multi-stage sampling, and administering on
them Life Satisfaction Index, Big Five Inventory, and a Personal Data Inventory,
analyses of data using Simple Linear Regression revealed that
(i) extraversion predicted life satisfaction among educated adults in age
category 20-39 years only, and not in adults in age categories 40-59 years
and 60+ years.
(ii) neuroticism predicted life satisfaction among educated adults in all the
different age categories.
Based on the finding, recommendations were made to Nigerian
Governments and many relevant others and agencies, in the lives of
Nigerian adults to use the opportunity of the knowledge of the importance of these factors
in life satisfaction judgements among adults to help Nigerian adults feel satisfied with
their lives.
