Community Integration Measure

Acquired Brain Injury: (McColl, et al, 2001; total n=92, acquired brain injury=41, college students=15, family members=36; mean age of ABI=35.4 (10.7); gender=male 58%, female 42%)

• Excellent internal consistency (Cronbach’s alpha=0.87)
• Excellent internal consistency for ABI (Cronbach’s alpha=0.83)
• Adequate for College students (Cronbach’s alpha=0.78)
• Excellent internal consistency for Family members (Cronbach’s alpha=0.92)
• All items correlated positively with each other and with the total score
• Adequate internal consistency for item to total correlations (0.416-0.714)

Acquired Brain Injury (CVA, TBI, tumor, encephalitis, aneurysm): (Reistetter et al, 2005; total n=91, ABI n=51, normal n=40; ABI mean age=38.82 (14.99); ABI gender=male 72.5%, ABI time since injury=1 years, 41.2%, 2 years: 37.3%, > 3 years: 21.6%)

• Excellent internal consistency (Cronbach’s alpha=0.81)
• Slightly higher internal consistency for individuals who sustained a brain injury −0.83, as compared to 0.72 for individuals without brain injury
• By living arrangement: living independently, Cronbach’s alpha=0.80; residing in family homes, Cronbach’s alpha=0.82
• Across gender: male, Cronbach’s alpha=0.82; female, Cronbach’s alpha=0.81 

Acquired Brain Injury (MVA, aneurysm/CVA, Trauma, Other): (Minnes et al, 2003; n=64; mean age=36.7)

• All ten items correlated positively with each other, and item-total correlations were between 0.28–0.66 

Traumatic Brain Injury: (Griffen et al, 2010; n=279; mean age at time of assessment=44.9 (13.60); gender: male 80.6%)

• Internal consistency estimate (Cronbach’s aplha) for the entire sample was .87.
• Internal consistency by time since injury (Cronbach’s alpha): 1 year = .86, 2 years = .85, 5 years =.87, 10 years =.86, and 15 years = .90.

Acquired Brain Injury: (McColl et al, 2001; total n=92, acquired brain injury=41, college students=36, family members=15; mean age of ABI=35.4 (10.7); gender=male 58%, female 42%)

• A positive correlation between the Community Integration Questionnaire (CIQ) and CIM (r=0.34) 
• There is some common variance between the 2 measures (12%) but do not duplicate each other’s content; authors suggest that CIQ emphasizes on independence while the CIM does not

Acquired Brain Injury: (McColl, et al, 2001; total n=92, acquired brain injury=41, college students=36, family members=15; mean age of ABI=35.4 (10.7); gender=male 58%, female 42%)

• A significant difference between groups (F 91,2 : 5.5, p < .006), with most marked difference between the participants with ABI and college students 
• A significant correlation between CIM and Interpersonal Support Evaluation List (ISEL) total, ISEL informational and ISEL emotional (See table below)

*p<.05; + p<.01

Acquired Brain Injury (CVA, TBI, tumor, encephalitis, aneurysm): (Reistetter et al, 2005; total n=91, ABI n=51, normal n=40; ABI mean age=38.82 (14.99); ABI gender=male 72.5%, ABI time since injury=1 years, 41.2%, 2 years: 37.3%, > 3 years: 21.6%)

• Community Integration Questionnaire (CIQ-R): significant positive correlation was found (r = 0.343, n = 91, p = 0.001), indicating that there is 12% shared variance between the two community integration instruments 
• Satisfaction With Life Scale (SWLS): 27% shared variance was found with the SWLS (r = 0.515, n = 91, p < 0.001), showing a good correlation between the CIM and life satisfaction as measured by the SWLS 
• Of the ten items for the CIM, eight produced significant positive correlations with the SWLS total score
• Significantly discriminate between samples (t(89) = 2.30, p = 0.024, CI 5.5–0.40)
• The factor loading solution revealed a three-factor model that explained 63.72 % of the variance

**p<0.01; *p<.05; p>0.05

Acquired Brain Injury (MVA, aneurysm/CVA, Trauma, Other): (Minnes et al, 2003; n=64; mean age=36.7; gender=male 79.7%)

• The one factor principal components factor solution explained 35% of the variance
• Correlations among reduced sub-scales and quality of life: The Assimilation, Integration, Marginalization, Segregation (AIMS) is negatively correlated with the two other scales, although only significantly with the CIQ-R; remaining correlations are all positive, but not statistically significant; none of the scales correlated with quality of life

Traumatic Brain Injury: (Griffen et al, 2010; n=279; mean age at time of assessment=44.9 (13.60); gender: male 80.6%)

• Most strongly correlated with the SPS, a measure of social support (r = .51, p <.01)
• Poor to Adequate correlations observed between the CIM and psychological and affective distress, the BSI-18 (rs from –.23 to –.37, p <.01), the SF-12 mental composite score (r =.37, p< .01), and the SWLS (r =.32, p <.01)
• Poor correlations with the subscales of the CHART including Social Integration (r =.18, p <.01), Cognitive Independence (r = .14, p <.05), Mobility (r =.14, p< .05), and Occupation (r= .23, p <.01), as well as with the SF-12 physical composite score (r =.14, p < .05)
• Not significantly correlated with the Physical Independence subscale of the Craig Handicap Assessment and Reporting Technique—short form (CHART) (r = .04, p<.49)
• Poor to Adequate correlations at one year post-injury between the Occupation and Social Integration subscales of the CHART and the CIM (r = .44, p <.01; r = .33, p <.01, respectively); no significant correlations existed between the CIM and the Cognitive Independence and Mobility subscales
• At 2 years post-injury: CIM did not correlate significantly with any of the CHART subscales, similarly, at 5 and 10 years
• Post-injury, the CIM did not significantly correlate with the CHART, with the exception of the Cognitive Independence subscale (r =.31, p < .05; r =.28, p <.05, respectively)
• At 5 and 15 years post-injury: the CIM was not significantly correlated with the SWLS, but it was at every other year. 
• CIM was significantly correlated with the SF-12 mental composite score for each year except year 5. 
• SF-12 physical composite score was significantly correlated with the CIM in years 2 and 5. 
• Until year 10, the CIM significantly correlated with each of the subscales and GSI of the Brief Symptom Inventory-18 (BSI-18) 
• At 15 years post-injury: the significant correlations with the CIM were the Mobility and Occupation subscales of the CHART, the SF-12 mental composite score, and the Social Provision Scale (SPS) 
• The CIM had significant correlations with the Social Provision Scale (SPS) at each time frame post-injury.

Acquired Brain Injury: (McColl et al, 2001; total n=92, acquired brain injury=41, college students=36, family members=15; mean age of ABI=35.4 (10.7); gender=male 58%, female 42%)

• The empirical, qualitative process leading to model development was well conceived and exhaustive 
• The items on the CIM have a 1-to-1 relationship with concepts in the model 
• The items on the CIM were constructed by using the words of participants themselves, ensuring authenticity and credibility authenticity and credibility.
