Title of Assessment

FACILITATOR AND BARRIERS SURVEY of environmental influences on participation among people with lower limb MOBILITY impairments and limitations 

Acronym

FABS/M

Instrument Reviewer(s)

Summary Date

 

Purpose

Assesses mobility limitations among people with lower limb impairments

Description

Activities and domains are computed for 7 questions on participation:
  • Frequency / time spent
  • Importance, choice, and satisfaction
  • Health-related limitations
  • Personal assistance and environmental accommodations, adaptations, or special equipment.


Five self-care activities do not include an assessment of importance. The maximum possible score for all participation questions for the 20 activities is 135

Criterion Validity (Predictive/Concurrent)

Not Established

Construct Validity (Convergent/Discriminant)

People with Mobility Impairment: (Gray, et al, 2006)
  • Excellent canonical correlation between the Reintegration to Normal Living (RNL) and the PARTS/M (r = .71 (p < .001)

Discriminant validity of the FABS/M was supported by the differences in scores for environmental features by diagnostic category and assitive device groups.  See Gray et al (2008) for more information.

Content Validity

Interviews used to develop the measure were based on the International Classification of Functioning, Disability and Health as a conceptual framework.

Face Validity

The PARTS/M was developed with the help of persons with mobility limitations. The views of these participants were captured through personal interviews, concept focus groups, and content focus groups

Professional Association Recommendations

Considerations

  • The hard copy version requires approximately 60 to 90 minutes to complete; the web based version takes about 40 to 60 minutes to complete
  • Unlike the Measure of the Quality of the Environment (MQE) and The Craig Hospital Inventory of Environmental Factors, the FABS/M was designed specifically for people with mobility limitations.
