title: Factors influencing quality of life in Chinese patients with persistent somatoform pain disorder.
abstract: This cross-sectional survey aimed to explore quality of life (QoL) and its correlated factors in Chinese patients with persistent somatoform pain disorder (PSPD) and their related correlation factors in Shanghai, China. A total of 60 patients were assessed with Short Form (36) health survey (SF-36) for QoL, medical outcomes study pain measurement (MOSPM) for pain symptoms, Hamilton depression scale - 17 items (HAMD) for depression and Hamilton anxiety scale (HAMA) for anxiety. Results were as follows: (1) Patients scored significantly lower on all SF-36 subscales' scores ( p < .01) apart from the mental health and vitality subscales; (2) With the exception of the general health subscale, SF-36 subscales' scores were negatively correlated with the total score of MOSPM, three factor scores of MOSPM, and total scores of HAMD and HAMA; (3) PSPD patients with severe depression had significantly lower scores (p < .01) on SF-36 subscales' scores (except for GH subscale) and component summary scores as compared to PSPD patients with none or moderate depression; and (4) Multiple linear stepwise regression revealed that SF-36's physical component summary (PCS) subscale correlated with patients' age and MOSPM total score while SF-36's mental component summary (MCS) subscale correlated with total scores of HAMD and MOSPM total score. In sum, PSPD patients had a lower QoL as compared to general population. Pain, depression, and anxiety were significantly correlated with QoL of PSPD patients while age, pain, and depression were important factors influencing PCS and MCS.
