Abstract

OBJECTIVE:

In primary care populations in Western countries, high somatic symptom severity (SSS) and low quality of life (QoL) are associated with adverse psychobehavioural characteristics. This study assessed the relationship between SSS, QoL and psychobehavioural characteristics in Chinese general hospital outpatients.

METHODS:

This multicentre cross-sectional study enrolled 404 patients from 10 outpatient departments, including Neurology, Gastroenterology, Traditional Chinese Medicine [TCM] and Psychosomatic Medicine departments, in Beijing, Shanghai, Chengdu and Kunming. A structured interview was used to assess the cognitive, affective and behavioural features associated with somatic complaints, independent of their origin. Several standard instruments were used to assess SSS, emotional distress and health-related QoL. Patients who reported low SSS (PHQ-15<10, n=203, SOM-) were compared to patients who reported high SSS (PHQ-15≥10, n=201, SOM+).

RESULTS:

As compared to SOM- patients, SOM+ patients showed significantly more frequently adverse psychobehavioural characteristics in all questions of the interview. In hierarchical linear regression analyses adjusted for anxiety, depression, gender and medical conditions (SSS additionally for doctor visits), high SSS was significantly associated with "catastrophising" and "illness vulnerability"; low physical QoL was associated with "avoidance of physical activities" and "disuse of body parts"; low mental QoL was associated with "need for immediate medical help."

CONCLUSION:

In accordance with the results from Western countries, high SSS was associated with negative illness and self-perception, low physical QoL with avoidance behaviour, and low mental QoL with reassurance seeking in Chinese general hospital outpatients.
