A significant proportion (approximately 10-30%) of adult-onset asthma is related to workplace exposure. The scope of the burden associated with asthma is multifactorial; asthma’s health, personal, social and economic impacts have been well established. However, living with asthma may also have significant psychosocial impacts. For example, studies have linked symptoms of psychological distress (e.g., anxiety, depression) to increased asthma severity, increased use of emergency services, increased symptom reporting, poorer pulmonary function, lengthier hospital stays, and increased use of reliever medication. Despite strong associations between psychosocial stress, psychological disorders, and “non-occupational” asthma morbidity, these associations remain virtually unexplored in patients with OA. The primary objectives of the present study are (1) to estimate the prevalence of comorbid psychological disorders and psychosocial distress in patients referred for evaluation of OA; and (2) to assess the influence of psychosocial factors (e.g., psychological disorders, levels of psychosocial distress) on occupational status, asthma symptomatology, health service utilization, and quality of life 12 months post-evaluation in patients receiving eventual diagnoses of OA and various differential diagnoses (e.g., Hyperventilation Syndrome, Panic Disorder, other psychological disorder).
