Efficacy impacts of psychological factors on primary dysmenorrhea treated with acupuncture / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between psychological factors and efficacy of acupuncture on primary dysmenorrhea.</p><p><b>METHODS</b>Sixty cases of primary dysmenorrhea were observed. Before acupuncture treatment, the self-designed confidence questionnaire was used to assess patients' confidence in acupuncture efficacy. Visual Analogue Scale (VAS) was adopted to assess patients' tension level during acupuncture. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were applied to assess the situations of patients' anxiety and depression. Eysenck's personality questionnaire (EPQ) and Cattell sixteen personality factors questionnaire (16PF) were provided to assess the personal characters of patients. Pain intensity, pain duration and accompanied symptoms were recorded before and after acupuncture treatment so as to assess the efficacy. Canonical correlation analysis was used to analyze the relationship between the psychological factors and acupuncture efficacy on primary dysmenorrhea.</p><p><b>RESULTS</b>There were significant differences in grading of dysmenorrhea, pain intensity score and pain duration after treatment as compared statistically with those before treatment (all P<0.001). The standardized coefficients of dominance (r=0.6797) and anxiety (r=-0.5906) in personality factors and the reduction of pain duration (r=0.9042) among efficacy indices were the highest. The overall correlation coefficients were all lower between the indices of psychological factors and canonical variables of dysmenorrhea efficacy.</p><p><b>CONCLUSION</b>Acupuncture efficacy on primary dysmenorrhea has a certain correlation with dominance and anxiety of patients' personality factors. But, the psychological factors do not play a leading role in acupuncture treatment.</p>
