A survey in the Santa Clara (California) direct supervision jail attempted to measure stress as well as other factors including job satisfaction, work attitudes, and officer effectiveness. The findings indicated that the main issue is not the amount of job-related stress, but the officer's effectiveness and how he feels about himself in his job. Compared to officers in traditional jails, officers in direct supervision jails were more satisfied with their jobs, reported lower levels of overall stress and job-related stress, and reported fewer instances of on-the-job hassles and stress-inducing events.
