[Quality assurance in therapy of chronic pain. Results obtained by a taskforce of the German Section of the Association for the Study of Pain on psychological assessment of chronic pain : VI. Instruments for the assessment of disability VII. Psychological instruments for the assessment of pain relevant aspects of social interaction and communication.]

Disability is a central aspect in the assessment of chronic pain patients. Disability questionnaires in German (developed or adapted) are examined and selected for different purposes. The "Funktionsfragebogen Hannover" and the "Pain Disability Index" are recommended for both research and clinicalapplication while the "Sickness Impact Profile" is suitable only for research purposes.Four different German questionnaires for the assessment of social interaction and communication in pain patients and their significant others are examined in part VII. There are some empirical data for three of them. Only the "Inventory of Familial Adaptability and Cohesion" has achieved a certain degree of empirical maturity. Further research and developmental activity in this area of pain assessment are urgently needed.
