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.

Permissions/Where to Obtain: Not available.
