Psychometric Evaluation of the Nursing Outcome “Pain: Adverse Psychological Response” in Patients With Chronic Pain

PURPOSE To culturally adapt into Spanish and validate the outcome “Pain: Adverse psychological response” (code 1306) in patients with chronic pain. METHODS A three‐stage study was conducted: (a) translation and cultural adaptation, (b) content validation, and (c) clinical validation. FINDINGS The Spanish version of the outcome “Pain: Adverse psychological response” has high content validity ( 0.91). Fourteen indicators were organized into two factors. This version offers good reliability in both inter‐observer agreement (kappa = 0.72) and internal consistency (alpha = 0.89). CONCLUSIONS The Spanish adaptation of “Pain: Adverse psychological response” is a reliable and valid instrument for the measurement of emotional aspects of chronic pain. IMPLICATIONS FOR NURSING PRACTICE The Spanish adaptation of this outcome offers nurses a set of structured indicators to measure the adverse emotional impact of chronic pain.
