Assesses the overall impact of environmental barriers across 5 domains.
Calculated by both the frequency and the degree of problem encountered.
Domains assessed include:
1) Accessibility
2) Accommodation
3) Resource availability
4) Social support
5) Equality
CHIEF: Scores are calculated by multiplying each of the 25 items with the frequency score (range: 0 to 4 ) by magnitude (range: 1 to 2) to yield a an overall “impact” score (range: 0-8).
1) Frequency: frequency with which barriers are encountered
2) Magnitude: indicates the size of the problem the barrier presents
3) Frequency magnitude product: Product of frequency X magnitude to determine overall impact of the barrier
CHIEF-SF: 12 item version developed from original CHIEF maintains all 5 subscales. It is composed of those items with the highest scores, indicating greater barriers, highest correlations with subscale and total scores, greatest conceptual clarity and discriminant validity (differentiating between those with and without disability); Scores are calculated as stated for the CHIEF using only 12 items within the original 5 subscles instead of 25 items.
The following criteria were utilized to determine which items of the CHIEF long form should be retained for inclusion in the CHIEF-SF:
1) Items that had the highest frequency of barrier mean scores
2) Items that had the highest magnitude of barrier mean scores
3) Items that had the highest item score-subscale score correlations
4) Items that were the most frequently reported barriers
5) Items that best differentiated between people with and without disability
6) Items were also kept if the authors conceptually felt they should be included in the scale

Test/Retest Reliability

SCI and TBI : (Quoted from Whiteneck, Meade, et al, 2004; n = 103; 2 weeks between assessments)

Excellent CHIEF total score test-retest reliability (ICC > 0.90)
Excellent sub-scale test-retest reliability (ICC's ranged from 0.77 to 0.89)

Multiple Diagnosis (Spinal Cord Injury, Traumatic Brain Injury, Multiple Sclerosis, Amputee, Cerebral Palsy, Auditory/Visual impairments, Developmental Disabilities): (Whiteneck, Harrison-Felix, et al, 2004; n=125 (SCI=46; TBI=54; Others=25); 2 weeks between assessments; CHIEF long form was used in this study)

Subject-Proxy Agreement (family members/friends of the 125 participants: Adequate total score test retest reliability (ICC=.62)

Internal Consistency

SCI, TBI, MS, Amputation, or "other" impairment: (Whiteneck, Harrison-Felix et al, 2004; 2 samples n = 97 (50 with disabilities and 40 without disabilities), n= 409 with disabilities; mean age = 44)

Internal Consistency (Cronbach's alpha)
Scale:	Strength	alpha
Total scale	Excellent	0.93
Physical and structural barriers subscale	Adequate	0.77
Policy barriers subscale	Adequate	0.77
Work and school barriers subscale	Excellent	0.81
Attitude and support barriers subscale	Adequate	0.79
Services and assistance barriers subscale	Adequate	0.76

Construct Validity

Discriminant Validity

Multiple Diagnosis: (Whiteneck, Harrison-Felix, et al, 2004; n=409 (SCI=124; TBI=120; Multiple Sclerosis=55; Amputees=35; Auditory/Visual Impairments, developmental disabilities, cerebral palsy, multiple impairments=75 )

All CHIEF items, all subscales, and the total score produced statistically significant differences across the impairment groups
People with disabilities consistently reported an overall higher level of environmental barriers on all subscales and the total CHIEF score
People with severe disabilities in the disability sample (eg, those with SCI, TBI) generally scored higher on subscales and the total score than the full range of people reporting any disability in the BRFSS sample
People with TBI scored lower on physical barriers than those in the other 2 major disability groups (SCI, other diagnoses)
People with SCI reported more barriers related to personal equipment, but attitudes in the home were more problematic for people with TBI

Multiple Diagnosis and population-based sample: (Whiteneck, Harrison-Felix, et al, 2004; n=409 (SCI=124; TBI=120; Multiple Sclerosis=55; Amputees=35; Auditory/Visual Impairments, developmental disabilities, cerebral palsy, multiple impairments=75; BRFSS sample=2269; development of the CHIEF-SF )

Correlations between CHIEF subscales and total score from the long form and short form ranged from .794 to .960
Mean score findings are consistent with the CHIEF long form findings

Content Validity

Spinal Cord Injury, Traumatic Brain Injury, MS, amputation or “other” impairment : (Whiteneck, Harrison-Felix, et al, 2004; n = 97 (50 with disabilities and 40 without disabilities), 409 = with disabilities; mean age = 44)

All CHIEF items, all subscales, and the total score produced statistically significant differences across the impairment groups
People with disabilities consistently reported an overall higher level of environmental barriers on all subscales and total CHIEF score than those without disabilities
People with severe disabilities generally scored higher on subsclaes and the total score than the full range of people reporting any disability.

Content validity was demonstrated through the consensus of 4 Subject Matter Experts (SME's) charged. The SME panel created 4 instruments that largely overlapped with each other. These instruments were then synthesized into a single measure (see Whiteneck et al, 2004 for more information).

Test/Retest Reliability

SCI and TBI : (Quoted from Whiteneck, Meade, et al, 2004; n = 103; 2 weeks between assessments)

Construct Validity

Population based sample (in Colorado): ( Whiteneck, Harrison-Felix et al., 2004 (n=2269; (mean age=44; gender=57% male; with and without disabilities)

Initial principle components factor analysis of the CHIEF’s 25 item product scores: 6 factors with eigenvalues over 1.0.
After varimax rotation, the 5-factor solution (accounting for 48% of the cumulative variance) was far more interpretable.
The 5 factors formed logical constructs, which were labeled “attitude and support barriers,” “services and assistance barriers,” “physical and structural barriers,” “policy barriers,” and “work and school barriers.”
