Instrument Reviewer(s) |
Initially reviewed by the Rehabilitation Measures Team; Updated by Wendy Romney, PT, DPT, NCS, Cara Weisbach, PT, DPT, and the SCI EDGE task force of the Neurology Section of the APTA in 2012; Updated by Sue Saliga PT, DHSc, CEEAA and the TBI EDGE task force of the Neurology section og the APTA in 2012

Summary Date |

|
Purpose |
Generic, patient-report measure designed to assess health-related quality of life
|
Description |
- 36 item measure divided into 8 subscales
- The 8 subscales are:
- (1) Physical Functioning
- (2) Role Limitations due to Physical Problems
- (3) General Health Perceptions
- (4) Vitality
- (5) Social Functioning
- (6) Role Limitations due to Emotional Problems
- (7) General Mental Health
- (8) Health Transition
- Respondents are asked to answers items referring to the past 4 weeks
- Recommended scoring system for the SF-36 is a weighted Likert system for each item
- Items within subscales are totaled to provide a summed score for each subscale or dimension.
- Each of the 8 summed scores is linearly transformed onto a scale from 0 (negative health) to 100 (positive health) to provide a score for each subscale.
- For each domain mean score = 50 and standard deviation = 10
- Version 2 norms are based on the 1998 National Survey of Functional Health Status (NSFHS); more information on version 2 can be found on the SF-36 website: http://www.sf-36.org/tools/sf36html

Chronic Spinal Cord Injury : (Anderson et al, 1999 n=181 veterans with SCI who were hospitalized within 6 months of assessment)
- Excellent to adequate correlations between SF-36 and Behavioral Risk Factor Surveillance System (BRFSS) subscales
- Mental Capacity Summary to all BRFSS subscales (r= -0.427—0.761 )
- Mental Health subscale to all BRFSS subscales (r= -0.446- -0.795)

- Poor to adequate correlations between SF-36 subscales Physical Functioning, Role Physical, Bodily Pain, General Health and Physical Summary and all BRFSS subscales (r= 0.065- 0.597)
- Poor to adequate correlations between SF-36 and Quality of Well Being (r= 0.044 to 0.417) (poor ≤0.03; adequate 0.31-0.59)
- Adequate to Poor correlation between SF-36 and IADLs (r= -0.159- to -0.454)

Traumatic Brain Injury: (Findler et al; n=597 (without disability, n=271; mild TBI, n=98; moderate-severe TBI, n=228); Mean age at interview=no disability, 38.5(12.7); mild TBI, 41.7(10.8), moderate-severe TBI, 35.7(9.8)
Mild TBI:
- Adequate to excellent correlations (-0.50 to -0.63) were found between SF-36 scales pertaining directly to physical functioning (General Health, Physical Functioning, Physical Role, Bodily Pain, Vitality) and the Physical symptoms scale of the Symptoms Checklist (SCL)
- Excellent correlations between SF-36 scales and participants’ Health Problems List (HPL) responses (-0.60 to -0.75)
- Emotional Role and Mental Health scores were more strongly related to psychological factors (Cognitive and Affective/Behavioral) than to physical factors on the Symptom Checklist (SCL)
Adequate to excellent correlations (-0.52 to -0.77) were found between Beck Depression Inventory second edition (BDI-II) scores and the SF-36 subscales
Moderate to Severe TBI:
- Correlations were lower and more uniform, strongest correlations found between the SF-36 Emotional Role scale and the SCL Affective/Behavioral scale (-0.53).
- Correlations between the Physical Functioning scale of the SF-36 and the Cognitive and Affective/Behavioural scales of the SCL were lower than other correlations between scales within this group (-0.11 and -0.19, respectively).
Multiple Neurologic Diagnosis (polio, acute stroke, and TBI): McNaughton et al., 2005; n=308, Polio n=38, Stroke n=181, TBI n=89; mean age=polio 62.5 (11.3), stroke=74.4 (12.0), TBI=34.0 (17.8); gender, female=polio 27%, stroke 96%, TBI 32%)
- examined validity of the mental component score (MCS) and physical component score (PCS)
- Principal component analysis (PCA) on the 12-month measures for subjects with stroke and TBI: 2 dimensions might account for a large proportion of the variability in the data set
- Varimax rotation shows that the 2-factor model has 85% of the variance of the underlying variables with 1 factor loading mainly onto the Barthel Index, Functional Independence Meausre (FIM), PCS,Community Integration Questionnaire (CIQ), and London Handicap Scale (LHS) and the other factor mainly onto the MCS
|
|
Traumatic Brain Injury: (Guilfoyle et al; n=514; mean age=36.6 (16.1) years; gender=male 76.3%)
- Principal component analysis (PCA) of the correlation matrix of the eight SF-36 domains extracted a single PC with an eigenvalue exceeding unity, which explained 59.2% of the variance in the data
- The second PC extracted had an associated eigenvalue of 0.75, and accounted for only 9.4% of the variance
Known Groups
Traumatic Brain Injury: (Findler et al; n=597 (without disability, n=271; mild TBI, n=98; moderate-severe TBI, n=228); Mean age at interview=no disability, 38.5(12.7); mild TBI, 41.7(10.8), moderate-severe TBI, 35.7(9.8)
- mild TBI and moderate to severe TBI groups reported significantly lower health status across all scales compared to the comparison group
- mild TBI group reported significantly lower scores (poorer health)on all scales compared to the moderate± severe TBI group, with the exception of Physical Function, where there were no differences between the two groups

Content Validity |
Items that compose the SF-36 were drawn from a number of prior measures including:
- The General Psychological Well-Being Inventory (GPWBI) (Dupuy, 1984)
- Physical and role functioning measures (Patrick, Bush, & Chen, 1973; Hulka & Cassel, 1973; Reynolds, Rushing, & Miles, 1974; Stewart, Ware, & Brook, 1981)
- The Health Perceptions Questionnaire (HPQ) (Ware, 1976)
- The Functioning and Well-Being Profile (FWBP) (Stewart & Ware, 1992)

Responsiveness |
Chronic spinal cord injury: (Lin et al, 2007)
- Highly sensitive (ES =0.60& 0.92) with respect to employment status with Physical Functioning and Role Physical domains.
- Moderately sensitive (ES =0.21-0.44) with respect to employment status with Social Functioning, Role Emotional and Mental Health domains
- Small responsiveness (ES= 0.00-0.16)with respect to employment status in Bodily Pain, General Health, and Vitality domains.

- The largest effect sizes were for sub-scales assessing social, emotional, and mental health, but there were moderate to large effects across all of the eight sub-scales, suggesting that TBI may have very broad effects across many different life parts.

Professional Association Recommendations |
|
Considerations |
Physical function domain: significant floor effects for patients with SCI and other disabilities due to inability to perform some of the physical tasks described. Recommend the SF-36 state “walkwheel” to improve responsiveness for patients with spinal cord injury. (Lee et al. ,2009)
Not recommended for:
- Patients who cannot understand written or spoken language
- Severely affected stroke survivors who require a proxy to complete the assessment
- To document patient change (Dorman et al., 1999)
- Some disadvantaged populations, slight declines in reliability may result (Turner-Bowker et al., 2002)
- Postal administration of the SF-36 is not recommended (O'Mahony et al, 1998)
- The Mental Health Subscale of SF-36 (MHI-5) VanLeeuwen, 2012 may be used in the future to determine mental health and severe mental health problems in persons with SCI. Cut off score ≤72 and ≤60 respectively.
- The SF-12 is a shorter version of the SF-36 containing 12 items; covers the summary physical health and mental health scales, but no information about each of the eight dimensions of the SF-36
- The SF-12 is beginning to be more commonly used in the TBI population however its psychometric properties in this population have not been specifically assessed (Nichol et al, 2011)
