Pain Disability Index (PDI)
Description: A measure of the degree to which pain interferes with functioning [1].
Format: Respondents rate the degree to which pain interferes with functioning in 7 broad areas: family/home responsibilities, recreation, social activity, occupation, sexual behaviour, self-care, and life-support activity.
Scoring: Scores are assigned based on an 11-point scale ranging from 0 (no disability) to 10 (total disability). Scores range from 0 to 70. The higher the index the greater the person’s disability due to pain.
Administration and Burden: Self-administered.
Psychometrics for SCI: The PDI is valid and reliable, with an internal consistency of .88 [2].
Languages: English.
QoL Concept: The PDI is a measure of Social Participation in relation to pain, which corresponds to C(achievements) and E (subjective evaluations and reactions) of Dijker’s Model.
