Discriminant Validity

Traumatic Brain Injury: (Willer et al, 1993, n = 446)

• Patients with brain injury were significantly less integrated on all subscales of the CIQ than non-injured participants. However, injured and uninjured females were equally integrated into home activities. *p-values not reported 

Traumatic Brain Injury: (Willer et al, 1993 and 1994) 

• Significant between-group differences on CIQ scores were reported in groups of TBI vs non-injured respondents. 

Traumatic Brain Injury: (Burleigh et al, 1997 and Willer et al, 1994) 

• Significant between group differences on CIQ scores in groups of independent vs supported vs institutionalized living environment (Burleigh et al, 1997 and Willer et al, 1994). 
• A significant difference was found between the three residential groups on the home integration subscale scores (Burleigh et al, 1997) 
• Significant difference between participants living in supported apartments and a residential shared home on home integration subscale scores (Burleigh et al, 1997)

Traumatic Brain Injury: (Winkler et al, 2006; n=40; mean age at injury=28; mean age at time of study=36.77; mean length of PTA=65.18 days (35.05)) 

• Groups identified as high vs low integration via cluster analysis demonstrated significant differences on CIQ

Traumatic Brain injury: (Willer et al, 1993)

• Three groups of 14 rehabilitation experts created the pilot version of the CIQ. Each was then asked to focus on ones aspect of community integration (family integration, social networks and occupational integration). 
• Pilot version of the measure was tested on 49 TBI patients diagnosed with moderate to severe TBI. 
• Factor analysis resulted in 3 factors that largely mirrored those of the three groups of experts.

Traumatic Brain Injury: (Sanders et al, 1999; n = 312 TBI patients > 12 post-event; retrospective study)

Based on this data, the authors concluded:

• Subscale scores are sensitive at one year post injury 
• There does not appear to be a substantial floor effect one year post injury, although the "Productivity Activity" subscale may be more susceptible to floor effects than other subscales.
• There does not appear to be a substantial ceiling effect one year post injury, although the "social integration" subscale may be more sensitive to ceiling effects.

Traumatic Brain injury: (Gurka et al, 1999; n=88 at 6 months follow-up and n=79 at 24 month follow up; mean age=33 years (12) at 6 months follow up and mean age=39 (16) at 24 month follow up) 

• Scores are normally distributed; sensitive to a range of levels of community integration (6 and 24 months post-rehabilitation discharge) 

Traumatic Brain Injury: (Hall et al, 2001; n=48; mean age=37 years; mean years post injury=5 years) 

• Ceiling effects of 33%, 48% and 44% reported for productivity, social and home integration sub scales, respectively 

Traumatic Brain Injury: (Corrigan and Deming, 1995; n=461 individuals with TBI (n=104)and other disabilities (eg, stroke, SCI, non-traumatic brain injury, orthopedic injury, neurologic injury, other) (n=357)) 

• Normal distributions for CIQ total scores, home integration and social integration sub scales; productivity sub scale positively skewed with restricted variability in TBI samples

Change Over Time:

Traumatic Brain Injury:

• Significant change over time reported before and after rehabilitation interventions(Seale et al, 2002 and Willer et al, 1999); in pre-morbid to post-injury ratings (Corrigan and Deming, 1995)
• Smallest detectable difference (SDD) = 6.18, SDD%=20.6 (insufficient sensitivity to change (van Baalen et al, 2006; n=25 at discharge and n=14 patients one year post injury study)

Chronic SCI: (Gontkovsky et al, 2009; n = 28; AIS (% of sample), A = 32.1, B= 32.1, C= 14.4, D = 21.4; mean age = 42 (17) years, at least one year post injury)

Chronic SCI : (Gontkovsky et al, 2009)

• CIQ and CHART-SF total scores positively and significantly correlated 
• CHART-SF total score significantly correlated with all three CIQ subscales 
• CIQ total score significantly correlated with 4 of 6 CHART-SF subscales (no correlation with economic self-sufficiency and physical independence) 

Chronic SCI : (Jensen et al, 2005; n = 147; (% of sample) C1-4 = 15.6, C5-8 = 34.7, T1-5 = 10.2, T6-12 = 32.0, L1-S4/5 = 7.5; mean age = 48.8 (13.0) years; measured twice 2 to 6 years between assessments; mean time since injury 16.6 (10.4) years)

**Statistically significant differences in SF-36 MHI and social integration in individuals with and without pain suggest poorer psychological functioning and social integration among individuals who report pain.

Convergent Validity

Spinal Cord Injury: (Saffari et al, 2015; n= 220; Mean age= 58.18 (10.32); Time post injury (months)= 50.96 (35.05))

• CIQ subscale scores correlated with scores from the Spinal Cord Lesions Coping Strategies Questionnaire (SCL-CSQ) (r > 0.40)

•   Excellent test-retest reliability (ICC = 0.96)

Convergent Validity

Chronic Stroke with Aphasia: (Dalemans et al, 2010) 

• Poor correlation with the Dartmouth Coop Functional Health Assessment Charts (r = -0.16) 
• Adequate correlation with the Barthel Index (r = 0.41) and Life Satisfaction Questionnaire (r = 0.35)

• Excellent: ICC Home integration found to be .9830 for single raters and .9914 for average measures.

Geriatric Population: (Singh & Sharma, 2015) n= 30, Mean + S.D = 72.96 Cronbach¡¯s Alpha = .799, SD = 4.987, Mean = 22.90

Physical Disability: (Hirsh et al., 2011; Spinal Cord Injury (n=146), Multiple Sclerosis (n=174), Limb Loss (n=158), or Muscular Dystrophy (n=372); Mean Age=50.86(13.48); time post Injury not reported). 

• Total score, Cronbach¡¯s alpha = 0.75 (Adequate to Good)
• Home integration, Cronbach¡¯s alpha = 0.84 (Adequate to Good)
• Social integration, Cronbach¡¯s alpha = 0.51 (Poor) 
• Productive activities, Cronbach¡¯s alpha = 0.45 (Poor)

Burn Injury: (Gerrard et al., 2015; n=492; Mean Age=41(14); 6 months post injury) 

• CIQ-15 was changed to a 13 item questionnaire with two factors: Self/Family Care and Social Integration. 
• Total score, Cronbach¡¯s alpha = 0.79 (Adequate to Good)
• Self/Family Care (Items 1-3, 5-7), Cronbach¡¯s alpha = 0.80 (Adequate to Good): Response options ¡°yourself alone¡± and ¡°yourself with someone else¡± were combined to form only one option for items 1-3. The two original options were seen as personal preferences rather than community integration limitations. Dropping item #4 (childcare) improved the CIQ¡¯s psychometrics. Not all respondents had children. However, the item should not be removed altogether, so as to not lose potentially meaningful data from those with children. 
• Social integration (Items 7-10, 12-15), Cronbach¡¯s alpha = 0.77 (Adequate to Good): Item 7 was put in both Self/Family Care and Social Integration factors. Item 11 on the CIQ was also taken out of this statistic because it was deemed "not clinically meaningful.¡± No information is given why item 11 was not clinically meaningful.

Discriminant Validity

Physical Disability: (Hirsh et al., 2011; Spinal Cord Injury (n=146), Multiple Sclerosis (n=174), Limb Loss (n=158), or Muscular Dystrophy (n=372); Mean Age=50.86(13.48); time post Injury not reported). 

• Post Hoc comparisons indicated that MS group reported better functioning on Home Integration than the SCI group. However, the difference was modest (Cohen's d=.30) and no other significant differences were found.
• CIQ does not demonstrate measurement invariance across disability groups.
