Considerations

Motor items in the FIM instrument have been shown to have cross-diagnostic Differential Item Functioning (DIF), indicating varying level of difficulty of items pending diagnosis which reduces comparison between patients. (Lundgren-Nilsson, 2006; Kucukdeveci A, 2001)
Subjective reports of pain (15.5%) and loss of strength (17.9%) were most frequently identified as causes of change in FIM instrument activities and quality of life for individuals with chronic SCI (Price et al. 2004)
For assessment of individuals with SCI, Rasch analysis indicates a four-category rating scale vs. the original seven-category scale has increased reliability (Nilsson, et al. 2005)
With Rasch analysis, the FIM instrument had decreased cross-cultural validity of raw motor scores with 7 of 13 items suggesting that FIM Motor Subscale scores should not be pooled in their raw form or compared between countries. (Lawton et al, 2006)
Rasch analysis indicates decreased correlation for difficulty of bladder and bowel management and individuals’ ease of performing tasks. (Lundgren-Nilsson, 2006)
“The FIM instrument does not contain key activity or participation elements of patient recovery important for measuring outcome and burden of illness (e.g., return to work, relationships, social and recreational pastimes, etc.)”( Nichol et al., 2011)
The FIM instrument is appropriate for patients at all levels of EDSS; rating reflects limited responsiveness data, training required, and copyright issues (MS EDGE task force)
The FIM instrument must be administered by a trained and certified evaluator and ideally scored by consensus with a multi-disciplinary team. Although the FIM instrument was originally developed to address issues of sensitivity and comprehensiveness for Barthel Index (BI), subsequent studies demonstrated that psychometric properties of the FIM instrument and BI are similar (Hsueh et al, 2002; Stroke EDGE task force)

Rasch Analysis of FIM

Questions on the uni-dimensionality of the FIM Motor Scale have been raised. Thus, data from 340 patients involved in post stroke rehabilitation were fitted to a Rasch model. The FIM Motor Scale satisfied Rasch model expectations including the uni-dimensionality assumption without requiring deletion of any of the 13 items. This analysis reinforces that the FIM Motor Scale contains clinically important items. (Lungren Nilsson et al 2011)

A secondary Rasch analysis combning the FIM and the Nottingham Extended Activities of Daily Living (NEADL) assessment was done on 188 participants (average of 19.45 ± 15.96 months post-stroke) from an upper extremity intervention trial. The scoring on the FIM was recoded to a 3-point scale to indicate degrees of independence and the final model (from both assessments) contained 36-items, the bowel management item was removed as it was highly correlated (0.81) with the bladder management item (Chen, 2013).

Barthel Index is commonly administered by nursing and medical staff to measure functional recovery following an inpatient stay for patients post stroke or neurologic disorders while the rehabilitation staff use the FIM. Barthel Index can be measured directly or estimated from the Northwick Park Dependency Scale (NPDS) or the FIM. Following hospital discharge of 717 patients (TBI and stroke), there was excellent agreement of intra-class correlations between the total scores on the FIM and the NPDS (0.93; P<0.001; 95% CI 0.92-0.94). Item by item agreement ranged from adequate ( 0. 41;dressing) to excellent (0.77;mobility) with the average absolute item % agreement from 7l.l% (Dressing) to 90.6% (transfers). (Turner et al, 2010)

Comments from StrokEdge Task Force Members

The FIM instrument must be administered by a trained and certified evaluator and ideally scored by consensus with a multi-disciplinary team. Although the FIM instrument was originally developed to address issues of sensitivity and comprehensiveness for Barthel Index (BI), subsequent studies demonstrated that psychometric properties of the FIM instrument and BI are similar (Hsueh et al, 2002; Stroke EDGE task force)

“The FIM instrument does not contain key activity or participation elements of patient recovery important for measuring outcome and burden of illness (e.g., return to work, relationships, social and recreational pastimes, etc.)”( Nichol et al., 2011) The FIM instrument is appropriate for patients at all levels of EDSS; rating reflects limited responsiveness data, training required, and copyright issues (MS EDGE task force)

Diversity Sensitivity of FIM

The FIM instrument was examined in white, black, and Hispanic people post-stroke that were admitted to inpatient rehabilitation. FIM scores were tracked at admission, discharge, three and 12 months after discharge. At three months, black and Hispanic patients had lower FIM totals when compared to whites. In addition, total FIM ratings increased for all three group form discharge to three months post, but then showed little change after. Racial/ethnic group, age, length of stay and medical comorbidities were significant predictors of total FIM ratings over the four time points. (Berges et al, 2012; Stroke EDGE task force)

FIM converted to other Languages

et al, 2015). Internal consistency and reliability were measured with the Japanese FIM+FAM-J in 42 patients a mean 30.2 (± 21.2) days post CVA .

Excellent internal consistency was observed for the FIM+FAM-J (full scale [0.968], motor scale [0.954] and cognitive subscales [0.949])
Excellent intra rater reliability was observed within the FIM+FAM-J full scale, motor subscale and cognitive subscale ((0.83, 0.80 and 0.98 respectively).
Excellent criterion validity was measured between the FIM+FAM-j full scale and the Motor Scale with the Barthel Index [ BI], the National Institutes of Health Stroke Scale [NIHSS], modified Rankin Scale [mRS] and Brunnstrom Recovery State [BRS L/E] (r=0.83, -0.75, -0.82 and 0.79 respectively with the total scale and 0.88, -0.77, -0.87, and 0.83 respectively for the motor scale)
Adequate criterion validity of the FIM+FAM-J cognitive scale with the BI, NIHSS, mRS and BRSL/E (0.56, -0.53,-0.54 and 0.53 respectively)
Adequate correlations with the Mini Mental Status Examination [MMSE] and the Frontal Assessment Battery [FAB] ( 0.60 and 0.58) but a floor effect with the Catherine Bergego Scale [CBS].

(Naghdi et al, 2016) Two raters administered the Persian FIM and the Barthel Index to 40 patient, mean age of 60 (±14.9) years old and an average of 21 (± 23) months post first stroke .

Excellent intra-rater reliability was measured {0.88-0.98)
Internal consistency of the PFIM was excellent, ranging from 0.70 to 0.96
Construct validity was supported by a significant Pearson Correlation between the PFIM and the Persian Barthel Index (r=0.95)

Systematic Reviews

In a systematic review of outcome measures used with patients post stroke participating in robot-assisted exercise trials (RAET), the FIM^TM Motor Scale was used as a measure of activity level in 9 of 28 RAET trials. With scores ranging from 13-91, the MCID was 11. The FIM Motor Scale had high/excellent reliability (test-retest and inter-rater reliability) and high/excellent validity (>0.75) However, the FIM Motor Scale had only moderate responsiveness (0.4-0.74), with chronic stroke survivors with severe impairments (persisting beyond 6 months) demonstrating little change on the FIM Motor Scale. As a measure of global physical activities, the FIM Motor Scale may be impacted by many other factors beyond specific arm function. The CAHAI or the ARAT may be a more appropriate arm outcome measure for stroke survivors with severe impairments. (Sivan et al, 2011)

Minimally Clinically Important Difference (MCID)

Stroke:

(Beninato et al, 2006; n = 113; mean age = 63.9 (14.3) years; mean FIM score at admission = 63.4 (24.4) points, Acute Stroke)

FIM Total Score = 22 points
FIM Motor Subscale = 17 points
FIM Cognitive Subscale = 3 points

Normative Data

Stroke:

(Inouye et al, 2001; n = 243; mean age = 64 (11) years; assessed at admission and discharge, Acute Stroke)

FIM scores of > 73 at admission were significantly younger (58 + 11 [SD] yr) than patients with FIM scores of 37 to 72 (64 + 11 yr) or scores < 36 (66 + 12 yr)
FIM total scores of 37 to 72 at admission showed higher gains (37 + 15) than patients who scored > 73 (20 + 10) or < to 36 (29 + 23)

(Tur et al, 2003; n = 102; mean age = 61.6 (10.9) yeas; 45-60 minutes of daily physical and occupational therapy, speech therapy daily as needed; Turkish sample, Acute Stroke)

	Admission Mean (SD)	Median	Discharge Mean (SD)	Median
FIM Total Score	69.2 (27.4)	69	83.2 (25.7)	86
FIM Motor	43.8 (20.7)	40	55.9 (20.3)	60
FIM Cognitive	25.9 (10.7)	31	27.2 (9.5)	32.5

Internal Consistency

Stroke:

(Hsueh et al, 2002; n = 118; mean age = 67.5 (10.9) years; measured at inpatient rehab admission and discharge, Acute Stroke)

Excellent internal consistency (FIM Motor Subscale) (Cronbach's alpha = 0.88 admission; 0.91 discharge)

Criterion Validity (Predictive/Concurrent)

Predictive Validity Evidence:

Stroke:

(Inouye et al, 2001; n = 243; mean age = 64 (11) years; assessed at admission and discharge, Acute Stroke)

Patients with FIM total scores of 37 to 72 at admission showed higher gains (37 + 15) than patients who scored > 73 (20 + 10) or < to 36 (29 + 23)

(Denti et al. 2004; n = 359; mean age = 80.8 (4.7) years; time between stroke onset and admission = 22.3 (14.6) days, Acute Stroke)

FIM total scores at admission were found to be the most powerful predictor of Montebello Rehabilitation Factor Scores (Beta coefficient = 0.42)

Concurrent Validity Evidence:

Stroke:

(Hsueh et al, 2002; Acute Stroke)

Excellent correlation between the FIM Motor Subscale and the 10-item version of the Barthel Index (BI) (r = 0.92 (at admission) - 0.94 (at discharge))
Excellent agreement between the FIM Motor Subscale and 5-item version of BI (r = 0.74 (at admission) - 0.94 (at discharge))

(Salter et al, 2010) 134 patients, a mean age of 68.64 (± 14.2) years old, and an average of 31.84 (± 59.2) days post-stroke, receiving care in an inpatient rehabilitation setting, were tested with the FIM at admission and discharge.

There was excellent, positive and significant correlations with performance at admission and discharge on the FIM (total and motor) with the Clinical Outcome Variables Scale [COVS] (0.823 and 0.771 respectively).
The COVS and FIM had excellent correlation (-0.61,-0.69)) with length of stay (P<0.01), such that lower scores at admission meant shorter length of stay.

(Ward et al, 2011) Thirty inpatients with first ischaemic stroke were evaluated with the FIM, the SIS-16 and the STREAM at admission:

The FIM score was significantly (P<0.001) and highly correlated (excellent) with the predicted length of stay (-0.9438 ) and the actual length of stay (-0.6846)
The validity of the FIM for predicting the LOS was higher (-0.9438) than the SIS-16 (-0.6743) and the STREAM (-0.8011)
The validity of the FIM associated with the actual LOS was lower (-0.6846) compared to the SIS-16 (-0.7953) and the STREAM Total (-0.7972).

(Yang et al, 2013). In a prospective observational study of 122 patients with a first time stroke admitted to a rehabilitation center over a 12 month period:

The FIM score on admission and discharge significantly predicted the Pittsburgh Rehabilitation Participation Scale [PRPS] (0.53; P<0.0001 and 0.40; P<0.001 respectively)
The level of participation on discharge (PRPS score) was predicted by functional status on admission (FIM; 0.309), cognitive impairment (Elderly Cognitive Assessment Questionnaire-ECAQ; 0.249) and fatigue (Fatigue Severity Scale-FSS; -0.304) .
Patients with lower levels of participation were more likely to be functionally dependent, cognitively impaired and have more fatigue.

(O’Brien et al, 2013). A sample of 371,211 Medicare beneficiaries who were receiving services in an inpatient rehabilitation facility (IRF) within 60 days post stroke (> 65 years of age, 43.7% male, 41.7% right sided impairment, 796% white) were evaluated with the FIM at admission and discharge. In addition, the change in LOS at the IRF and community discharge was compared over time with the implementation of a prospective payment system (PPS) for individuals on Medicare.

Average LOS decreased a total of 3.8 days (from 17.9 in 2002 to 16.1 days in 2007)
Mean admission FIM scores decreased a total of 4.4 points ( from 57.2 to 53.8 points)
The mean discharge FIM sores decreased a total of 3.6 points ( from 80.1 to 76.5 points) in 4 of 5 years with no significant decline in 2004.
Frequency of community discharges declined steadily with an average overall decrease of 5.4 % (from 6.6% to 61.2%) over the 5.5 years of study
Controlling for study year and covariates, each day in IRF was associated with an increase of 0.50 discharge points (95% CI = 0.48, 0.52)
The association between LOS and discharge destination was excellent, averaging 0.997 (95% CI = 0.994, 0.999) based on the co-variates of admission FIM, age, gender, ethnicity, side of lesion, complications and year.

(Van Heugten et al, 2015) Systematic review of studies (51) investigating convergent, criterion and predictive validity of cognitive dysfunction in patients in the acute phase (4 weeks) post stroke using multi-domain instruments.

The Conistat, Montreal Cognitive Assessment [MOCA] and Functional Independence Measure-Cognitive showed adequate predictive validity

(Bates, 2015-Part 1) A retrospective analysis of 4020 veterans receiving consultative or comprehensive rehabilitation care post-stroke. The study examined initial characteristics of veterans predictive of grade IV achievement on the FIM.

The final model contained the following variables: age, initial physical grade, initial cognitive stage, renal failure, nutritional compromise, type of rehabilitation services, and recovery time between admission and discharge assessments. A point system was assigned to each of the above variables, such that the clinician could enter in the above information and determine the likelihood of a patient achieving a grade IV. The area under the ROC curve was adequate of the derivation and validation cohorts (0.84 and 0.83, respectively). The Hosmer-Lemeshow statistic was not significant (ρ = 0.93).

(Bates, 2015-Part 2)

The above model (Bates, 2015-Part1) was enhanced to become a prognostic index, predicting likelihood of recovery to or above the grade VI benchmark (Modified Independent). There was adequate fit with a nonsignificant Hosmer-Lemeshow statistic of P = 0.38 and Adequate area under the curve of 0.83 in the derivation cohort and 0.82 in the validation cohort. A similar predictive equation was derived with the sum score quartiles slightly modified.
(Huang, 2010) Fifty-eight participants an average of 17.85 (range, 7-88) months post-stroke participated in distributed constraint induced therapy two hours per day, five days a week for three weeks. Assessments were administered prior and after therapy, and a Chi-squared Automatic Interaction Detector method was used to identify the strongest predictors of change on the Stroke Impact Scale. Participants with an initial Total FIM score ≤ 109 at admission, improved significantly more (P = 0.006) on the Stroke Impact Scale and on measures of activities of daily living and instrumental activities of daily living at completion of the intervention.

(Lin, 2010) Seventy-four participants an average age of 54.11 (± 11.44) years old and 17.46 (± 17.67) months post-stroke were seen for upper extremity intervention. Participants received constraint-induced movement therapy, bilateral arm training, or conventional rehabilitation for two hour sessions, five times per week for three weeks. Assessments were done at baseline and post-intervention.
Poor to excellent predictive validity was found between the domains of the Stroke Impact Scale and the FIM (0.26-0.70, p < 0.05)
Poor to excellent predictive validity was found between the domains of the Stroke Specific Quality of Life Scale and the FIM (0.22-0.63, p < 0.01). The language, personality, thinking, and vision domains were not significant.

(Ward et al 2011) On admission to the acute rehabilitation ward, the FIM and the STREAM were found to be highly correlated in thirty patients acute post ischemic stroke.(ρ=0.7766; P<0.0001)

(Shindo et al, 2015) To explore the concurrent validity of the FIM scale with the Simple Test of Evaluation Hand Function [STEF], 34 inpatients (33-86 years of age) sub acute post stroke (less than 60 days post episode) were evaluated at admission. The STEF had statistically significant, adequate correlations with the FIM^TM: FIM Total score (0.444;P<0.009), FIM motor (0.411;P<0.016) and FIM self care (0.402; P<0.019) .

et al, 2014) The aim of this study was to explore the validity of the Cognitive Behavioral Rating Sale ( CBRS) with the FIM discharge data on 100 patients, mean age of 72.2 (± 10.9) years old and 61.0 (±61.2) days post-stroke. The Spearman Rank Correlation Coefficient was excellent between the CBRS and the FIM total Score (-0.70; p<0.01), the Cognitive FIM (-0.72; P<0.01), and the Motor FIM (-0.63; p<0.01) for patients post stroke.

(Caglar, 2014) A retrospective analysis on 142 patients post-stroke that went to an IRF. A linear regression was run to determine which factors contributed to Motor-FIM (M-FIM) gain and Cognitive-FIM (C-FIM) gain.

The adjusted R² was 0.173 (p = 0.000) for M-FIM gain and the significant factors were the admission M-FIM (B = 0.809, SE = 0.199, β = -0.446, p = 0.000) and if the patient had diabetes Mellitus (B = 14.269, SE = 6.775, β = -0.177, p = 0.037).
The adjusted R² was 0.146 (p = 0.001) for C-FIM gain and the significant factors were the admission C-FIM (B = -4.068, SE = 1.048, β = -0.369, p = 0.000) and if the patient had diabetes Mellitus (B = 36.226, SE = 17.904, β = -0.175, p = 0.045).

(Cooke, 2010) One hundred and ninty-seven, first stroke participants were included an average of 45.4 ± 67.6 days post-stroke to examine the relationship of clock drawing post-stroke.

A significant relationship was found between the FIM-Motor and the Clock Drawing Test (Exp (B) = 0.984, p = 0.030).

Construct Validity

Convergent Validity Evidence:

Stroke:

(Tur et al, 2003; Acute Stroke)

Adequate correlation with length of hospital stay (r = -0.39)
Adequate to Excellent correlation with Brunnstrom’s motor recovery stages in upper extremity, lower extremity, and hand at admission and discharge (r = 0.51 - 0.68)

Discriminate Validity Evidence:

Stroke:

(Brock et al, 2002; Rasch analysis; n = 106; mean age = 68.7 (11.3) years; median time since onset = 11 days, Acute Stroke)

Difficult items on motor portion of the scale discriminated better among higher functioning patients
Raw FIM scores (as opposed to score subjected to Rasch analysis) may underestimate change

(Cavanagh et al, 2000; ischemic and hemorrhagic stroke patients, Stroke)

Simple 2-factor model of the FIM instrument may not be sufficient to describe disability following stroke (66% of variance)
May not adequately measure within patient change whereas a 3-factor model (self-care, cognition and elimination) accounted for more variance (74.2%)

No instrument (including the FIM) assessed all of the commonly affected cognitive domains after a stroke
Strong significant intercorrelations were found between the Occupational Therapy Cognitive Assessment (LOTCA), the MMSE and the FIM-Cognitive subscale

(Canbek, 2013) Fifty-five participants who experienced their first-ever stroke and went to an IRF an average of 8± 5 days post-stroke.

Poor to Excellent construct validity was seen between the FIM-Motor and the Tinetti POMA

	Tinetti POMA	Balance Domain	Gait Domain
Admission FIM-Motor	0.688	0.616	0.610
Discharge FIM-Motor	0.609	0.588	0.536
Change FIM-Motor	0.389	0.277	0.396

(Kucukdeveci, 2013) One hundred and eighty-eight community dwelling participants (mean age 63.1 ±12 years), a median of 27 (range 3-240) months post-stroke were evaluated on the FIM and the World Health Organization Disability Assessment Schedule (WHODAS-II).

Adequate to Excellent convergent validity was found. All correlations significant at p < 0.001.

	FIM Motor	FIM Cognitive
WHODAS-II understanding and communicating	-0.54	-0.74
WHODAS-II getting around	-0.86	-0.45

WHODAS-II -12 (work items removed)	-0.86	-0.65
WHODAS-II-10	-0.83	-0.65

(Ottiger et al A new multidisciplinary observation scale for inpatients post stroke based on the ICF model of activity and participation was created to document outcomes post stroke (LIMOS). This scale included four components of the ICF:1). interpersonal activities, [mobility and self-care,; 2}. Communication; 3} Knowledge and general tasks; 4) domestic life. The activities were rated as limitations or restriction in domains as: none, slight, moderate, severe or complete. This new scale was correlated with FIM scores.

Excellent convergent validity was found between the LIMOS and the FIM (r=0.89; P<0.0001)
An excellent association was reported between the FIM mobility subscale and the LIMOS mobility subscale (r=0.90; P<0.0001)
Adequate to excellant associations were found between the subscales of the LIMOS (self care, general tasks, domestic life) and the subscales of the FIM (r=0.36-0.79)

Floor/Ceiling Effects

Stroke:

(Brock et al, 2002; Acute Stroke)

Minimal ceiling effect: 16% achieved ceiling on FIM Motor Subscale during inpatient rehabilitation

(Dromerick et al, 2003; n = 95, Acute Stroke)

No floor or ceiling effects at either time using the FIM instrument

(Hsueh et al, 2002; Acute Stroke)

FIM Motor subscale:

Minimal floor effect at admission to inpatient rehab (5.8%) and at discharge from inpatient rehab (3.5%)
No ceiling effect at admission to inpatient rehab (0%) and at discharge from inpatient rehab (0%)

Responsiveness

Stroke:

(Hsueh et al, 2002; Acute Stroke)

Motor subscale:
- Large effect size with standardized response mean = 1.3

(Ward et al, 2011) A prospective cohort study of 30 subjects newly diagnosed with ischemic stroke (mean days since stroke onset 7.8 days (± 3.5)) was designed to demonstrate sensitivity of the FIM to change in an acute rehabilitation setting.

The FIM score on admission was significantly associated (adequate to excellent correlations) with discharge destination as well as predicted and actual length of stay.
The SRM (admission to discharge change score) was 2.34 for the motor FIM (P<0.0001). This FIM SRM was greater than the SRM for the SIS-16 and SRM for the STREAM.

(Salter et al, 2010) Following admission and discharge of 292 patients post stroke (134 with complete data and 158 with incomplete data, respectively an average of 31.8 and 67.3 days post stroke), FIM^TM scores improved significantly (P<0001) from admission to discharge from a mean of 73.86 (24.13) to 95.70 (24.65) . The SRM was 1.36.

Content Validity

The FIM instrument was based on the results of a literature review of published and unpublished measures as well as input provided by an expert panel. Face and content validity were determined using subject matter experts (Granger, Hamilton, Keith, Zielezny, & Sherwins, 1986).

Content validity was established through a pilot study done at 11 centers (n = 110 patients evaluated; Keith & Granger, 1987).

SCI:

(Jackson et al, 2008; n = 54 expert raters assessed locomotion measures as: 1) valid or useful, 2) useful but requires validation or changes/improvements, or 3) not useful or valid for research in SCI, SCI)

FIM – Locomotion item was rated as Valid/Useful by 6%, Useful But Requires Validation or Changes by36% , and Not Useful or Valid for Research in SCI by 58%

Face Validity

SCI:

(Grey and Kennedy, 1993; Chronic SCI)

Face validity was evaluated by asking clinicians specific questions addressing:
- Difficulty of understanding (88% had no difficulty)
- Unnecessary items (97% reported no unnecessary items
- Items that should be added (83% felt no extra items needed)

Floor/Ceiling Effects

SCI:

(Grey and Kennedy, 1993; Chronic SCI)

92% of subjects and 88% of clinicians reported a max score on communication
75% of subjects and 73% of clinicians reported a max score on social cognition

(Hall et al, 1999; Acute SCI)

Percentage of Floor and Ceiling FIM Scores by Level of Injury
	Admission	Discharge	1 yr	2 yrs	5 yrs
High Tetraplegia: C1 (no motor ceiling effect)
Motor Floor effect(%)*	86	21	28	25	13

* Floor effect: Score of 1; Ceiling effect: Score of 6 or 7

Responsiveness

SCI:

(Spooren et al, 2006; n = 60; mean age = 38.9 years old; first measurement taken when subjects were first able to sit up in a chair for 3 hours, Acute SCI)

Large effect size for all subjects regardless of AIS classification between initial measurement (T1) and 3 months later (T2) as well as between initial measurement (T1) and discharge from rehab (T3)
Small to moderate effect size for subjects between T2 and T3 (ES = 0.37-0.79)

Interrater/Intrarater Reliability

TBI:

(Donaghy & Wass, 1998; TBI)

Excellent interrater reliability (ICC = 0.85 for total FIM Scores, 0.92 for FIM Motor, and 0.69 for FIM Cognitive)

Criterion Validity (Predictive/Concurrent)

(Heinemann et al, 1994; Rehabilitation Patients)

Admission FIM Motor Scores accounted for 52% of variance in discharge motor function among TBI patients, admission FIM Cognitive Scores accounted for 46% of variance in discharge cognitive function – admission motor FIM was the most significant predictor of length of stay

(Montecchi et al, 2013) In 59 patients with mean age of 48.90 (± 14.01) years old, admitted to the intensive care unit acutely post acquired brain injury (from trauma, hypoxia, haemorrhage or ischemia), a new Trunk Recovery Scale (TRS) was developed.

Excellent correlation between the FIM-Motor and the TRS (0.849)

Content Validity

Content validity was established through a pilot study done at 11 centers (n = 110 patients evaluated; Keith & Granger, 1987).

Traumatic Brain Injury:

(Hall et al, 2001; TBI)

Although the FIM instrument is reliable and key validity characteristics have been established, it has only 5 items directly addressing cognitive, behavioral, and communication issues, which limits its content validity for TBI

Responsiveness

Excellent internal consistency (Cronbach's alpha = 0.93 admission; 0.95 discharge)

Neurological Disorders:

(Hobart et al, 2001; Neurological Disorders)

Excellent internal consistency (Cronbach's alpha = 0.95 FIM Total Score; 0.95 FIM Motor; 0.89 FIM Cognitive)

Criterion Validity (Predictive/Concurrent)

Predictive Validity Evidence:

Neurologic Disorders:

(Ng, et al., 2007; n= 1502; mean age of total = 61.3 ± 15.0 years; mean acute LOS = 14.5 ± 17.5 days; mean inpatient rehab LOS = 21.5 ±19.0 days, Neurological Disorders)

Admission motor FIM scores (β = 0.55) and admission cognitive FIM scores (β = 0.38) had the highest impact on discharge total FIM scores

Construct Validity

Discriminate Validity Evidence:

Rehabilitative patients:

(Hobart et al, 2001; n = 169; neurological rehab patient: MS, stroke, TBI, other)

FIM total and FIM motor scores correlated more strongly with OPCS disability scores, LHS scores, SF-36 physical component scores and WAIS – verbal IQ, than with measures of mental health status or psychological distress (SF36 mental component, General Health Questionnaire)
FIM Cognitive Scores correlated most strongly with OPCS Disability scores and WAIS-verbal IQ scores and weakly with LHS, SF-36 physical and mental components, and the General Health Questionnaire (ABIEBR)

Floor/Ceiling Effects

Rehabilitation Patients:
