Objective

The Shoulder Pain and Disability Index (SPADI) is a patient completed questionnaire with 13 items assessing pain level and extent of difficulty with ADLs requiring the use of the upper extremities. The pain subscale has 5-items and the Disability subscale has 8-items.

The original version[1] was published in 1991 and has its items scored on the Visual analogue scale while the second version scores its items on the Numerical rating scale(NRS)

SPADI has been translated in many languages including Spanish, Greek, Dutch, Hindi, Thai and Italian each with its own validity and reliability.

Intended Population

SPADI can be used in the following patient population:

Method of Use

The patient is instructed to choose the number that best describes their level of pain and extent of difficulty using the involved shoulder. The pain scale is summed up to a total of 50 while the disability scale sums up to 80. The total SPADI score is expressed as a percentage.

A score of 0 indicates best 100 indicates worst. A higher score shows more disability.

In scoring SPADI, any question missed should be taken out of the total score of each subscale. i.e if 1 question is omitted in the pain section, the total score is divided by 40.

Evidence

Reliability

SPADI was found to have reliability coefficients of ICC ≥ 0.89 in a variety of patient populations.[4] Internal consistency is high with Cronbach α typically exceeding 0.90[4]  

Validity

The SPADI demonstrates good construct validity, correlating well with other region-specific shoulder questionnaires.[5][4][6] It has been shown to be responsive to change over time, in a variety of patient populations and is able to discriminate adequately between patients with improving and deteriorating conditions.[7][8][4]

Responsiveness

The minimal clinically important difference has been reported to be 8 points; this represents the smallest detectable change that is important to the patient.[5] However, when SPADI is used repeatedly on the same subject the minimal detectable change is 18 points.[9][10]
