Protocol - Cognitive Function

Description

The PROMIS® Cognitive Function v.2.0 - Short Form 6a is a six-item sub-set scale of the PROMIS® Cognitive Function item bank that assesses patient-perceived cognitive deficits.

Specific Instructions

Instruct participants to answer all of the items (i.e., questions or statements) presented. Some administrators may prefer to ask the same question of all respondents or of the same respondent over time, to enable a more direct comparability across people or time

All scores must be presented as t-scores not raw scores. The T-score is the standardized score with a mean of 50 and standard deviation of 10.

T-scores can be generated in three ways:

Use a data collection tool that automatically calculates scores
Use the free on-line HealthMeasures Scoring Service
Score by hand using the Cognitive Function Scoring Manual Short Form 6a look-up table (see protocol)

Other notes:

Score-based Percentiles can be included as additional but not replacement information.
Higher scores indicate higher Cognitive Function.

The PhenX Working Group recommends this PROMIS® protocol.

Personnel and Training Required

None

Equipment Needs

The PhenX Working Group acknowledges that the questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil instrument). Computer software is needed to administer the instrument.

Requirements

Requirement Category	Required
Major equipment	No
Specialized training	No
Specialized requirements for biospecimen collection	No
Average time of greater than 15 minutes in an unaffected individual	No

Mode of Administration

Self-administered questionnaire

Lifestage

Adult

Participants

Adults (ages 18+)

Selection Rationale

The PROMIS® protocols were tested and found to be reliable and comparable to established measures of these same content areas. Additionally, they are quick and easy to administer, either via paper and pencil or as a computer-based instrument. The cognitive function instrument is universal rather than disease specific. The Cancer Outcomes and Survivorship Working Group chose this protocol because it is a short, valid, reliable general instrument. The Functional Assessment of Cancer Therapy—Cognition (FACT-Cog), is a longer alternative specific to cancer populations.

Definition

The PROMIS^® (Patient-Reported Outcomes Measurement Information System) Cognitive Function item bank assess patient-perceived cognitive deficits. Facets include mental acuity, concentration, verbal and nonverbal memory, verbal fluency, and perceived changes in cognitive functions. The extent to which cognitive impairments interfere with daily functioning, whether other people observe cognitive impairments, and the impact of cognitive dysfunction on quality of life are also assessed.

Purpose

This measure can be used to assess patient-perceived cognitive deficits and its impact on daily functioning.

Keywords
