Pain coping profiles in adolescents with chronic pain.

This study sought to evaluate the extent to which the pain coping profiles observed by Walker and colleagues in a sample of patients with chronic abdominal pain also were evident in a sample of adolescent patients who presented to a tertiary care clinic for evaluation of a variety of diverse pain conditions. In addition, we aimed to evaluate the relation of these pain coping profiles to patients' emotional and physical functioning. Participants (n=254) were adolescent patients aged 12-17 years. Patients completed the Pain Response Inventory (PRI) as well as measures of pain, somatic symptoms, anxiety and depressive symptoms, and functional disability. Using the PRI classification algorithm developed by Walker and colleagues, we successfully classified all the patients in our sample. We also found that the pain coping profiles successfully differentiated among patients with different levels of symptoms, disability, and emotional distress, further demonstrating the external validity of these profiles. Results have implications for tailoring pain treatment interventions to patients' particular coping profiles.

A typology of pain coping strategies in pediatric patients with chronic abdominal pain.

This study aimed to identify clinically meaningful profiles of pain coping strategies used by youth with chronic abdominal pain (CAP). Participants (n=699) were pediatric patients (ages 8-18 years) and their parents. Patients completed the Pain Response Inventory (PRI) and measures of somatic and depressive symptoms, disability, pain severity and pain efficacy, and perceived competence. Parents rated their children's pain severity and coping efficacy. Hierarchical cluster analysis based on the 13 PRI subscales identified pain coping profiles in Sample 1 (n=311) that replicated in Sample 2 (n=388). Evidence was found of external validity and distinctiveness of the profiles. The findings support a typology of pain coping that reflects the quality of patients' pain mastery efforts and interpersonal relationships associated with pain coping. Results are discussed in relation to developmental processes, attachment styles, and treatment implications.
