Traumatic Brain Injury: (Levine et al., 2000; n= 12 (mild), 16 (moderate-severe); mean age 32.3 (4.2) for mild, 31.0 (7.4) for mod/severe; time since injury 3.9(0.53) for mild, 3.6 (0.80) for mod/severe; participants tested 3-4 years post-injury; used the original SIP) 

• Revised Strategy Application Test (R-SAT) significantly related to SIP total score r(38) = -0.4, p <.05 for mod/severe group; correlations for controls and mild group were not significant 
• The R-SAT R-SAT performance was related to the SIP psychosocial summary score, r(38) = -.34, p < .05 and a significant relationship between the physical summary score and R-SAT performance, r(38) = -.50, p < .002

Niemann-Pick type C: (Koens et al, 2016; n = 8; age range 19-61 years; measured either directly after diagnosis up to 4 years post diagnosis);

• A Strong correlation was found between the severity of the movement disorder as measured by the Global Clinical Impressions Scale and the Physical and Psychosocial Dimension of the SIP 68.

*Global Impressions Scale-scale of 1-7, 1=no movement disorder, 7=most affected by movement disorder. Range for this population 2-5.

**Spearman’s rho

• The original SIP assesses three critical aspects of health recommended by the World Health Organization:

  • Physical Health

  • Mental Health

  • Social Health

• The SIP-68 is a shortened subset of this original set of items.

Literature Review: (de Bruin et al., 1997; n = 7; studies composed of different diagnoses) 

• Responsiveness for the SIP-68 = 0.62

• Responsiveness for the SIP-136 = 0.64

Acute Stroke: (Kwakkel et al, 2002; n = 37; mean age = 64.1 (15.0) years, (level of consciousness assessed within 24 hours of stroke onset) median Glasgow Coma Scale 15 (IRQ = 15–15), median Mini Mental State Examination score 26 (24–28) Dutch sample)

• SIP-68 baseline score = 41.2 (11.7)

Respiratory function in those with spinal cord injury: (Postma et al, 2016; n = 147; mean age 45.5 (13.8); 6.6 (0.8) years post initial inpatient rehabilitation stay; American Spinal Injury Association Impairment Scale (AIS) lesion level as shown:

• Mean (SD) SIP 68 Social Dimension for combined lesion levels 6.7 (4.7).

Chronic SCI : (Post et al., 1996, n = 315, mean age 39.4 years, AIS A-D, 1-7 years post injury) 

• Excellent internal consistency (r = 0.92)

Chronic SCI: (Post et al., 1996)

Chronic SCI: (Post et al., 1999; n = 318; mean age = 43.0 (range = 18 to 65) years; time since injury = 4.5 years; Dutch sample)

SIP-68 Correlations between demographic variables and Social Support:

*  p < 0.05; ** p < 0.01; SIPSOM = Physical dimension of functional health; SIPPSY = Psychological dimension of functional health; SIPSOC = Social dimension of functional health; all correlations have a strength of poor except age/SIPSOC

Chronic SCI: (Post et al., 1996)

Wheelchair-dependent Individuals: (Post et al., 2001; n = 111, Athletes = 49, SCI = 32 & Rheumatic diseases = 30; average ages range from 36.5 to 69.9 years)

Wheelchair-dependent Individuals : (Post et al., 2001)

Wheelchair-dependent Individuals: (Post et al., 2001)

* Correlations 0.19 or higher significant at p < 0.05 ; correlations 0.26 or higher significant at p < 0.01

Correlation Strength:

• > .60 = Excellent (IN BOLD)

• .31-.59 = Adequate
