Chronic Stroke: (van Straten et al., 2000; n = 407; mean = 70 (13) years; assessment at 6 months post stoke; Dutch sample)

• >33 Total or >40 Physical Dimension indicates impairment in ADLs, inability to live independently, difficulty with self-care, and difficulty with mobility and performing their main activity.

Chronic Stroke: (Taken from van Straten et al., 2000)

HRQL = Health Related Quality of Life; () = Percentage of patients correctly classified. Percentages  < 75% not shown; psychosocial dimension not shown because the percentage of patients correctly classified was < 75% on all ICIDH and HRQL measures

Chronic Stroke: (van Straten et al, 1997; n = 319; assessed 6 months post stroke; Dutch sample)

• Good to Excellent internal consistency

  • Total SA-SIP30, Cronbach's alpha = 0.85

  • Psychosocial Dimension, Cronbach's alpha = 0.78

  • Physical Dimension, Cronbach's alpha = 0.82

Chronic Stroke: (van de Port et al., 2004; n = 122; mean = 57 (12) years; assessed at 6 months and 1 year post stroke; Mean Barthel Index at inclusion = 12.7 (4.5); Dutch sample)

• Good to Excellent internal consistency

  • Total SA-SIP30, Cronbach's alpha = 0.82

  • Physical Dimension, Cronbach's alpha = 0.76

• Poor internal consistency

  • Psychosocial Dimension, Cronbach's alpha = 0.68

Acute Stroke: (Allen et al., 2002; n = 96; intervention group mean age = 69 (1.7) years, usual care group mean age = 72 (1.5) years; assessed 48 hours prior to discharge from acute stroke unit)

• Excellent internal consistency with removal of activities of daily living questions, Cronbach¡¯s alpha = 0.83

Chronic Stroke: (van de Port et al., 2004)

Mean scores (Standard Deviations) and Pearson correlation coefficients (r); *t-test, p < 0.05; 
**p < 0.01; Van Straten et al. (1997) created the Sickness Impact Profile (SA-SIP30) from the original SIP136

Convergent Validity:

Mild Stroke: (Edwards et al., 2006; n = 219; mean age = 64.74 (15.87) years; 6 months post-stroke)

• SA-SIP30 is a strong predictor of Reintegration to Normal Living (RNL) scores assessing life satisfaction

Severe Stroke: (Salter et al., 2005 ¨C critical review)

• The SIP-136 and SA-SIP-30 scale were shown to have lower levels of agreement when utilized with patients who have experienced a severe stroke. The SA-SIP30 does not assess pain, recreation, energy, general health perceptions, overall quality of life, or stroke symptoms.

Discriminant Validity:

Chronic Stroke: (Cup et al., 2003; n = 26; n = 24, six months post stroke onset; n = 2, two months post stroke onset; mean age = 68 (15) years)

• Poor correlations between the Canadian Occupational Performance Measure and SA-SIP30 (r = 0.102)

First-time chronic stroke: (Verhoeven et al., 2011; n = 209; mean age = 56.5 (11.3) years; one year and three years post-stroke)

• At one year post stroke, the Cambridge Cognitive Examination (CAMCOG) Orientation was a significant determinant of the SA-SIP-30 Psychosocial dimension, whereas CAMCOG Memory was a significant predictor of the SA-SIP-30 Physical dimension and CAMCOG Perception was a predictor of SA-SIP-30 Total score.

• At three years post-stroke, CAMCOG Perception was a significant determinant of SA-SIP-30 Total score and Physical dimension. CAMGOG Language was the only predictor of the SA-SIP-30 Psychosocial dimension.

• CAMCOG scores together explained 6.5% of the variance of the SA-SIP-30 Total score, 10.9% of the variance of the SA-SIP-30 Physical dimension, and 1.7% of the variance of the SA-SIP-30 Psychosocial dimension.

First-ever Supratentorial Stroke: (Schepers et al., 2006; n = 163; mean age = 56 (11) years; 6 and 12 months post-stroke)

• Comparison of the Barthel Index (BI), Functional Independence Measure (FIM), Frenchay Activities Index (FAI) and SA-SIP30:

  • Subacute phase (0-6 months post-stroke): recommended use of BI

  • Chronic phase (6-12 months post-stroke): the FAI and SA-SIP30 detected the most changes and had moderate effect sizes. Recommend use of the FAI and SA-SIP30 for chronic phase, especially for the stroke rehabilitation population

• FAI and SA-SIP30 focus more on instrumental ADL and social functioning - expected to show larger effect sizes in the chronic phase than the BI and FIM.

Stroke¡ªChronic Phase: (Schepers et al., 2006; n = 163; mean age = 56 (11) years; 6 and 12 months post-stroke)

• Because of its focus on IADLs and social functioning, larger effect sizes were shown in the chronic phase compared to the FIM and Barthel Index.

Poststroke Spasticity in the UE: (Doan et al., 2012; n = 279; mean age = 52.8 (NR) years)

• Greater disability scores in all problem domains on the Disability Assessment Scale were significantly associated with higher overall dysfunction scores on the SA-SIP30.

• Linear regression was used to assess the relevance of the 136 items with a forward selection strategy, using the F statistic with p = 0.5 as the criteria level for selection. 

• Item selection for each subscale was completed when the items in the regression model explained 80% of the variance in score of the original total subscale.

• Items listed within some of the subscales could potentially be included in other subscales (i.e., ¡®Stay home most of the time¡¯ and ¡®not going into town¡¯ is under mobility but could also be listed under social interaction) (Salter et al., 2008)

Chronic Stroke: (van de Port et al., 2004)

• Moderate Responsiveness; effect sizes (6 months to one year post-stroke):

  • Total SA-SIP-30 = 0.60

  • Physical Dimension = 0.56

  • Psychosocial Dimension = 0.65
