Quadriplegia Index of Function (QIF)
The QIF was developed in 1980 to provide a functional assessment that would be useful in documenting the small but clinically significant gains made by quadriplegics throughout in-patient rehabilitation (Gresham et al. 1986). This index assesses transfers, grooming, bathing, feeding, dressing, wheelchair mobility, bed activities, bowel program, bladder program and understanding of personal care. The first 9 areas represent functional performance activities and the final area is a questionnaire - designed to assess the client’s understanding of skin care, nutrition, equipment medications and infections.
Number of items: 37
Procedure/Administration: Information is collected in an interview format. Scores are provided to give credit for being able to complete a portion of the task rather than the entire task.
How scored: Each category of functional performance is calculated according to weighted scores - Functional performance categories: /180; Understanding of personal care: /20; Total: 200 /2 = /100. The functional performance categories are scored on a 5 point scale from 0 (dependent) to 4 (independent).
Interpretability: No information regarding interpretability of the scores (e.g.: norms or cut points) is provided.
Acceptability: The QIF was designed for the
Time to administer: Less than 30 minutes when the assessor is familiar with the measure.
Time to score: N/a
Training required: None
Equipment required: None
Inter O: Yellow light
Construct: Green light
Note: TR= Test re-test; IC= Internal Consistency; Inter-O= Inter-observer; Intra-O= Intra-observer; SS= Sensitivity/Specificity; N/a= No information.
Red light= A single study involving SCI subjects which has less than adequate findings of reliability, validity, and/or responsiveness.
Yellow light= A single study involving subjects with SCI which has adequate to excellent findings of reliability, validity, and/or responsiveness.
Green light= At least 2 studies involving subjects with SCI which have adequate to excellent findings of reliability, validity, and/or responsiveness.
