The demands for medical care of patients with chronic non-specific lung disease (CNSLD) and the prevalence of CNSLD will increase. The need, therefore, for behavioural research on CNSLD will also grow. In order to steer behavioural research in CNSLD, research programming is of great importance. Forty-seven Dutch and 13 foreign expert medical and behavioural scientists were asked via an interview about the most prominent topics and conditions for future research in this field. In addition a literature survey with the same aim was carried out. Important topics for future research include: quality of life of CNSLD patients, patient needs, psychophysiological investigation, social and psychosocial aspects of CNSLD, compliance, problems at work and school, and the education of those involved in patient care.
