Reports findings from studies that used the Time Structure Questionnaire (TSQ), an instrument designed to measure the degree to which individuals perceive their use of time as structured and purposive. Results from 3 samples of university students showed that the TSQ has acceptable psychometric properties. They also showed that TSQ total scores were positively correlated with a sense of purpose in life, self-esteem, reported health, present standing and optimism about the future, Type A behavior, and more efficient study habits, and were negatively correlated with depression, psychological distress, anxiety, neuroticism, physical symptoms, hopelessness, and anomie. Perceived use of time also varied with role demands, such as whether a person was single or married, employed or unemployed, or a part-time or full-time student.
