Quadriplegia Index of Function Modified (QIF-Modified)

Download Clinical Summary PDF

Tool Description

  • Comprised of 3 of the 10 domains originally included in the QIF.
  • Includes the categories of grooming, bathing and feeding.
  • This version of the QIF includes the categories that relate directly to the upper extremity motor score assessment of ASIA.

ICF Domain:

Activity – subcategory: Self-Care.

Number of Items:

14

Brief Instructions for Administration & Scoring

Administration:

  • clinician-administered; interview format
  • administration time is approximately 10 minutes
  • The functional performance categories are scored 0-4 in order of increasing independence.

Equipment: None

Scoring:

  • Each category of functional performance is calculated according to weighted scores

Interpretability

MCID: not established for the SCI population
SEM: not established for the SCI population
MDC: not established for the SCI population

  • Scores are provided to give credit for being able to complete a portion of the task rather than the entire task.
  • The scores represent functional performance in activities rather than performance in component parts.

Clinical Considerations

  • Designed specifically for SCI population.
  • ASIA motor scores are strongly correlated to performance improvement on QIF scores
  • It is not a comprehensive measure of upper extremity function or predictor of independence in ADLs upon discharge.
  • The QIF reflects small gains in function

Measurement Property Summary

# of studies reporting psychometric properties: 1

Reliability:

  • Inter-correlations of items within the same category for each domain:

o   Grooming: r=0.65-0.70

o   Bathing: r=0.67-0.93

o   Feeding: r=0.44-0.88

Marino et al. 1993

Validity:

  • Correlation of the modified QIF and its subscales with the Functional Independence Measure (FIM) subscales and the Upper Extremity Motor Score (UEMS) subscales measuring the constructs were High

o   QIF-modified and FIM: r=0.93

Subscale – Grooming: r=0.94

§  Subscale – Bathing: r=0.92

§  Subscale – Feeding:  r=0.75

o   QIF-modified and UEMS: r=0.91

§  Subscale – Grooming: r=0.90

§  Subscale – Bathing: r=0.84

§  Subscale – Feeding: r=0.90

  • Feeding ability was assessed by the QIF significantly better than by the FIM (P<.01)

Marino et al. 1993

Responsiveness:

No data on responsiveness was available for the QIF-modified.
