Quality of life in adulthood (ages 27-47) was investigated; age, marital status and sex were considered the primary variables. Attention was given to the consideration of the current crises-oriented theory of adult development. The interrelationship of the variables was of principle interest in assessing life satisfaction and personality development. An interview questionnaire form assessed 15 components considered important in determining the quality of life, and included sections on assessment of feeling and rank order lists of current concerns and sources of help. Subjects included 150 men and women, married and single; age groups were clustered around the 30, 35, 40 and 45 year milestones. Results suggest few differences on the relative importance of the 15 components; however, on most of the components, this population considered their needs inadequately met. Although age and sex did not influence life satisfaction; marital status did. Ranking of concerns and sources of help indicated age trends, affected by both sex and marital status. The results suggest that adult development should not be viewed solely as a series of age-related crises; rather, age interacts with the socially-related variables. Indicated trends over age suggest continued personality development through the adult period that appears somewhat consistent across subjects. (Author/BMW)
