 Pre-Testing

 

PROMIS conducted three rounds of testing items before September, 2006.  This included 1) item pretesting, 2) a mode of testing study, and 3) most of the full bank testing.  All testing was conducted through an online panel company.

PROMIS Participant Accrual

PROMIS Accrual Summary  (08.31.06)

  Item Pretesting Study  Mode of Testing Study Full Bank Testing Study
Testing Period May, 2006 July, 2006 August, 2006
Number Tested 110 805 3,173

I. Item Pretesting Study
Emotional distress items were submitted to a general population sample. The goal was to use test data to help select the final item set that would undergo further testing.

 

II. Mode of Testing Study
In designing the testing platform there was uncertainty about (1) whether or not a participant should automatically be forwarded to the next item after providing an answer and (2) if a participant should be able to go back to the previous item. A study was conducted using one of the social role participation banks. The four test conditions included (1) automatic advance with a back button, (2) automatic advance without a back button, (3) use of a “next item” button after selecting an answer with a back button, and (4) use of a “next item” button after selecting an answer without a back button. Test data were analyzed to help decide on the final test platform, which auto advanced after response and enabled respondents to go back an item.

 

III. Full Bank Testing Study
The final item banks were submitted to testing in a general population sample. Each participant completed two full banks of items (e.g., the Emotional Distress-Depression bank and the Emotional Distress-Anxiety bank).

 Wave 1 Goals

 Wave 1 Testing

 Wave 2 Goals

Incorporating feedback and recommendations from the PROMIS NIH science officers as well as the Scientific Advisory Board regarding direction of the next wave (Wave 2) of PROMIS network research activity, the SC decided to focus on validation of existing banks for the five domains versus development of new banks. The SC established a strategy for deciding on Wave 2 activity, which included defining study design and validation criteria for Wave 2 network protocols, defining clinical populations for study, and initiating draft protocols in:

 

v      Depression and low back pain with a community sample comparison

v      Arthritis

v      Congestive heart failure (CHF)

v      Chronic obstructive pulmonary disease (COPD)

 

It is anticipated that protocols will be finalized before the end of 2007. Evaluation of available network resources as reconciled with the study plans detailed in the protocols will determine how many of these four protocols can be conducted within the PROMIS funding period.
