Overview of PROMIS Network
University of Washington
This work was funded by the National Institutes of Health through the NIH Roadmap for Medical Research. Principal InvestigatorDeborah N. Ader, Ph.D.Director, Behavioral and Prevention Research ProgramNational Institute of Arthritis and Musculoskeletal and Skin DiseasesGoals, Network, TasksPresented by:Dagmar Amtmann, Ph.D.PI University of Washington Center for Outcomes in Rehabilitation Research
To improve assessment of self-reported symptoms and other health-related quality of life measures across disabilities.
The PROMIS is one of the key projects under the “Re-engineering the Clinical Research Enterprises” branch of the trans-NIH Roadmap Initiative. All NIH institutes contribute funds to the initiative.

Positive Impacts of Illness
Physical Function is defined as one's ability to carry out various activities, ranging from self-care (activities of daily living) to more challenging and vigorous activities that require increasing degrees of mobility, strength or endurance (Stewart & Kamberg, 1992; Haley, Coster & Binda-Sundberg, 1994; Haley, McHorney & Ware, 1994; Wilson & Cleary, 1995)*. Physical Function items, when considered as an outcome endpoint for clinical research in chronic illness, have a “capability” stem and a corresponding “capability” set of response items (e.g., “Are you able to…normally, with some difficulty, with moderate difficulty, with great difficulty, unable to do.”). This specifically excludes some items that may have great utility in other settings, as with “performance” items with the "Do you?" type of stem, which get at social or psychological issues, and “satisfaction” items (e.g., “How satisfied are you with your disability?”), which get at coping, stress, anxiety, etc. Also, since Physical Function/Disability is a much more fixed latent trait in chronic disease than Pain and some other domains, the response options will seldom be best expressed as "frequency" (“A little bit of the time”, etc.). Further, since many persons with a chronic disease will have more than one chronic disease and cannot distinguish the fraction of a problem attributable to each disease, Physical Function items attempt to quantitate the sum of these disease effects, leaving the teasing out of relative contributions to the analysis stage.
Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage (Sherbourne, 1992a; Merskey & Bogduk, 1994; Chang, 1999; Meuser, et al, 2001). Pain is what the patient says it is (that is, the "gold standard" of pain assessment is self-report).
Fatigue is defined as an overwhelming, debilitating and sustained sense of exhaustion that decreases one’s ability to carry out daily activities, including the ability to work effectively and to function at one’s usual level in family or social roles (Stewart, Hays & Ware, 1992; North American Nursing Diagnosis Association, 1996; Glaus, 1998).
Emotional distress refers commonly to unpleasant emotions or cognitions that may interfere with the ability to cope with a disease, its physical symptoms, and its treatment. It covers a wide range of feelings, including worry, powerlessness, sadness, fear, depression, anxiety and panic (Schag et al, 1994; Lawton, Parmellee, Katz & Nesselroade, 1996; van’t Spijker, et al, 1997; Bottomley, 1998a; 1998b; Stark, et al, 2002)*. Problems in mental health may also be manifested, however, in maladaptive behaviors less commonly associated with subjective distress. For example, research in psychiatric nosology (Krueger, 1999) suggests that the “structure of common mental disorders” (excluding psychosis) can be captured at a general (second-order) level by two dimensions of psychopathology: an internalizing dimension reflected in unipolar depression and anxiety disorders and an externalizing dimension reflected in alcohol and substance use and antisocial behavior.
Social Role Participation: Role participation refers to involvement in, and satisfaction with, one’s usual social roles, including marital relationships, parental responsibilities, work abilities and social activities (Sherbourne, 1992b; McDowell & Newell, 1996; Dijkers, Whiteneck & El-Jaroudi, 2000)*. This has also been referred to as social adjustment (McDowell & Newell, 1996).
