Background: Primary dysmenorrhea is one of the most prevalent disorders in women which results in their decreased efficacy. The aim of this study is to evaluate the effect of pressure on the third liver point on involved liver channel symptoms in patients with primary dysmenorrhea. Materials and Methods: This clinical trial was conducted on 194 students that met the inclusion criteria. In the first cycle, symptoms of involved liver channel were identified. Accordingly, participants were randomly allotted to either treatment or control groups. In the second, third and fourth cycles, acupressure was applied to the third liver point and placebo point for 20 minutes 3-7 days before menstruation. With bleeding in the fourth cycle, the symptoms of involved liver channel were determined. Results: In the first cycle, there were no significant differences in symptoms of involved liver channel between the two groups however, in the fourth cycle, the results of Chi2 test showed significant differences between the two groups in all symptoms of involved liver channel except the tongue with red spots (p<0.05). In the treatment group, a comparison of the first and the fourth cycle revealed significant differences in all symptoms of involved liver channel except for tongue with red spots (p<0.05). Conclusion: In this study, applying pressure to the third liver point was effective in the improvement of the majority of involved liver channel symptoms therefore, acupressure is suggested as a practical, effective, non-expensive, and available method in the treatment of primary dysmenorrhea.

Background: International AIDS questionnaire allows for making cross-cultural comparisons between individual’s levels of awareness and attitudes towards AIDS. This study assessed the reliability and validity of international AIDS questionnaire for Iranian student population. Materials and Methods: In this cross-sectional study, 448 students studying in non-medical sciences at universities in Qom were selected through convenience sampling. The participants completed the international AIDS questionnaire–Persian version (IAQ-P). Confirmatory and explanatory factor analysis, Pearson correlation, and Cronbach's Alpha were used in order to examine construct and concurrent validities, respectively. Independent t-test was run to compare the questionnaire scores between male and female participants. Results: The CFA supported the four-factor model, and the normative data showed patterns similar to previous research. Four dimensions of the questionnaire data were satisfactory (AGFI=0.91, GFI=0.93 and RMSEA=0.04, P<0.001). The total IAQ-P had a high internal consistency (Cronbach’s alpha=0.80). Cronbach’s alphas for the sub-scales were 0.78 (myths), 0.78 (attitudes), 0.79 (personal risk), and 0.60 (facts). After one month, test-retest study on a sub-sample of 41 students revealed Pearson correlation coefficient ranges from 0.36 to 0.75 (P<0.001). Conclusion: The IAQ-P was shown to be a valid and reliable instrument and the results of this study are similar to other versions of IAQ in other languages.
