Professional Association Recommendation

Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Considerations

The author states that the PADLS provides health professionals a reliable index of self-rated ADL, which takes little time to complete. The PADLS provides a single global rating and does not allow the individual to rate the severity of specific problems. The PADLS is not suitable for use in isolation and must complement existing measures in order to provide the health professional with more comprehensive information on how patients perceive their illness.

Normative Data

Parkinson’s Disease:

(Hobson, Edwards and Meara, 2001; n = 132 with clinically probable PD; mean age: 73.4(9.5); gender (male %): 55; onset of PD (years) 7.8(6.9); disease duration (years): 7.8 (6.9))

Mean PADLS score: 3.0 (1.2)

Test/Retest Reliability

Parkinson’s Disease:

(Hobson, Edwards and Meara, 2001) 

  • Excellent test-retest reliability (r = 0.89)

Construct Validity

Parkinson’s Disease:

(Hobson, Edwards and Meara, 2001) 

  • Excellent correlation between the PADLS and the Webster Scale, a measure of disease severity with higher scores indicating greater disease severity (0.65, p < 0.001). 
  • Adequate correlation between the PADLS and the CAMCOG, the cognitive section of the Cambridge examination for mental disorders of the elderly (-0.41, p < 0.001) 
  • Adequate correlation between the PADLS and the Geriatric Depression Scale (GDS-15) a 15 item self report of depressive symptoms (0.43, p < 0.001) 
  • Poor correlation between the PADLS and age of patient (0.24, p < 0.05) 
  • Poor correlation between the PADLS and whether the individual’s family visits (0.02) 
  • Adequate correlation between the PADLS and whether the individual’s friends visit (-0.43, p < 0.001) 
  • Adequate correlation between the PADLS and whether the individual is able to visit family (-0.32, p < 0.05) 
  • Adequate correlation between the PADLS and whether the individual is able to visit friends (-0.44, p < 0.001) 
  • Higher total and subset Parkinson’s Disease Quality of Life Questionnaire (PDQL) (better perceived quality of life) were negatively associated with higher PADLS scores
