Functional Status Examination

Last Updated

Purpose

The Functional Status Examination was designed to evaluate change in the activities of everyday life as a function of a sudden event or illness. It compares outcomes from current functional status to pre-injury status in physical, social, and psychological domains (Staudenmayer, Diaz-Arrastia, de Oliveira, Gentilello, & Shafi, 2007).

Key Descriptions

  • The full-length FSE = 10 items
  • The test is administered by way of interview.
  • If an individual with a TBI is unavailable or has a severe cognitive impairment, then a person who knows the individual well, such as a significant other, may be interviewed in place of the individual (Wise et al., 2010).
  • Severity within each area is measured along a four-category ordinal scale:
    0) No change from preinjury
    1) Difficulty in performing the activity, but still total independencefor areas
    2) Dependence on others some of the time to perform activities in that area
    3) Completely dependent on others or that the individual does not perform that activity at all
  • Ratings from each domain are summed to give an FSE total score.
  • A lower score denotes a more independent individual and a higher score denotes a more dependent individual.
  • The ratings are summed from each domain to give a score between 0-30. Individuals who have passed away before the completion of the assessment are given a score of 31 (Shukla, Devi, & Agrawal, 2011).
  • Scores across 10 functional domains:
    1) Executive functioning (cognitive competency)
    2) Social integration (behavioral competency)
    3) Personal care
    4) Ambulation
    5) Standard of living
    6) Home management
    7) Travel
    8) Financial independence
    9) Major activity involving work or school
    10) Leisure and recreation

Considerations

  • The FSE has demonstrated good reliability, validity, and sensitivity, and appears to be a promising instrument for monitoring recovery and assessing functional status in clinical trials (Dikmen et al., 2001).

  • The FSE is based on a structured interview and includes levels of functioning that accommodate the full spectrum of possible outcomes, from death through recovery to pre-injury functioning. (Nichol et al., 2011).

  • Functional Status Examination (FSE); a new measure of change in activities of everyday life as a function of an event or illness, has demonstrated reliability, validity, and sensitivity for monitoring recovery and assessing functional status in TBI, even long after the injury and in a mostly moderately injured group, particularly family burden and depression (Dikmen, et al 2001) and quality of life and psychosocial function (Temkin, et al 2003). 

  • In the literature, there is conflicting information on how the measure is scored. Some authors report that the total score for the FSE ranges between 0-30 with 31 denoting death (Skula et al, 2011). The reviewers have not been able to obtain a copy of the measure to help resolve this discrepancy.

Traumatic Brain Injury: (Nichol et al, 2011; Dikmen et al, 2001)

  • “the FSE has good test-retest reliability and is responsive to changes over the first 6 months following injury”

 

Traumatic Brain Injury: (Hudak et al, 2005; n=177)

  • The FSE has been demonstrated to be reliable and sensitive in monitoring recovery after TBI.
  • The Functional Status Examination (FSE) and the Glasgow Outcome Scale (GOS-E) are reliable outcome measures for TBI survivors, and FSE may offer some advantages over GOS-E due its ability to provide a more detailed description of deficits (Hudak et al, 2005).

 

Traumatic Brain Injury: (Hudak et al, 2012, n=471)

  • Excellent test-retest reliability (ρ = 0.8)

Internal Consistency

Traumatic Brain Injury: (Nichol et al, 2011; Hudak et al. 2005; Dikmen et al., 2001)

  • The FSE has demonstrated good reliability, validity, and sensitivity, and appears to be a promising instrument for monitoring recovery and assessing functional status in clinical trials.

Criterion Validity (Predictive/Concurrent)

Traumatic Brain Injury: (Powell et al., 2007; n= 164 rehabilitation inpatients (mean age 35.4 years, 77% men, 75% white) with moderate to severe TBI were examined in relation to demographics, injury severity, neuropsychological functioning, and living situation)

  • Home management performance: 59% reported more difficulty or more assistance with home management at 1 year. 

  • Nonperformance of individual activities before injury ranged from 16% to 76%. Age (p = .001), living situation after injury (p = .002), and neuropsychological function at 1 year (p = .001) were associated with more limited home management performance after injury as compared to premorbid function.

Construct Validity

Traumatic Brain Injury: ( Dikmen et al., 2001; n= 105; mean age= 33.15, 5 were un-testable)

Traumatic Brain Injury:

  • Sensitive to the range of recovery at 6–12 months post-injury (Dikmen, Machamer, Powell, & Temkin 2003).
  • FSE and GOS-E scores correlate well with each other (r= -0.38, P = ≤ 0.001 (Dikmen et al., 2001).
  • FSE scores and GOS-E scores showed a strong correlation of 0.83 (Hudak et al., 2005).

Content Validity

Traumatic Brain Injury:

  • The FSE is a self-report measure thus, it will have biased perceptions. (Wise et al., 2010)

Face Validity

Designed to cover domains of everyday functioning as defined by the World Health Organization. Also, creators of the FSE chose items based on their experiences with outcome measures and clinical research involving individuals with traumatic brain injury. (Dikmen et al, 2001)
The FSE is shown to demonstrate face validity (Temkin, Machamer, and Dikmen 2003; n=209).

Floor/Ceiling Effects

Traumatic Brain Injury: (Dikmen et al, 2001) 

  • Excellent: Total FSE did not show any floor or ceiling effects 

 

Traumatic Brain Injury: (Shukla, 2011; Hudak, 2005; n=177)

  • Excellent: FSE scores are distributed throughout the range, indicating that ceiling and floor effects are not present.

Responsiveness

Traumatic Brain Injury: (Nichol et al., 2011; Dikmen et al., 2001)
 

  • “The FSE has good test-retest reliability and is responsive to changes over the first 6 months following injury” 

 

Traumatic Brain Injury: (Dikmen et al., 2003; n=210; TBI patients)

  • 3 to 5 years post severe brain injury: “The results of the FSE indicate substantial functional limitations in every area of everyday life examined. Recovery to preinjury levels, as perceived by the subjects, ranges from a high of 65% of the cases in personal care to lows of 40% in cognitive competency, major activity, and leisure and recreation. Not being able to perform the activity or needing help from others partially or totally occurs in all areas, but particularly in major activity (work, school), financial independence, cognitive competency, social integration, and leisure and recreation”.
