Abstract
Laboratory and field interview methods for studying the effect of changing shift schedules on sleep patterns of American workers were evaluated. Under laboratory conditions four groups of workers defined by shift worked, sex, and physical work load were studied. Initially all were asked to complete personality tests to determine which workers were suited for laboratory study. Participation was agreed on by 72 workers who came to the laboratory 4 consecutive days in a week for laboratory sleep periods monitored with recording electrodes. Standard instruments and methods were used to evaluate performance at designated tasks, mood, and sleep. At all stages procedures were carefully explained and the workers' impressions were recorded. At completion of the study workers received a cash bonus. The field interview component of the study involved interviews of up to 3 hours at a time and place convenient to the worker. Two interviewers alternately interviewed each of 61 workers participating. An interview preceded a structured questionnaire concentrating on descriptive information. Subjects were not paid for the field interview. Both processes appeared effective. All workers except one in poor health completed the laboratory sessions, a much higher degree of cooperation than expected. The integration of the field interview into the entire work/sleep study apparently contributed to the efficiency of the whole study. The authors conclude that the multiple method approach allows a high degree of reliability. The high degree of cooperation was in part due to the careful preparation of study subjects.
