The Survey of Pain Attitudes (SOPA) and Chronic Pain Coping Inventory - 42 (CPCI- 42) on Portuguese Population

Abstract

The study presents the psychometric characteristics of the Portuguese version of The Survey of Pain Attitudes (SOPA, Jensen & Karoly, 2000) and Chronic Pain Coping Inventory-42 (CPCI-42, Romano, Jensen & Turner, 2003). In Study 1, Factorial Analysis of both measures was studied in 651 Portuguese adults, who attended a Health Care Centre. For SOPA, a 9 factor’s structure explained 61.319% of the variance (Control - Strategies of Self Control, Incapacity, Emotion, Solicitation, Medication; Control - Learning Strategies, Medical Healing, and Damage). Concerning CPCI-42, 6 factor’s structure explained 60.835% (Relaxing, Prevention, Search of Support, Self declarations, Takes Persistency and Exercise). The measure factors were adequate to the original model, presenting values of internal consistency highly superiors to those obtained originally.

A second study analyse the convergent and divergent validities of the obtained versions of SOPA and CPCI-42, in a 151 adult’s sample. Contributes of these measures were approached through the analysis of multiple regression, therefore explaining the symptoms of anxiety, depression and stresse. Results are discussed considering existing literature.
