Crossover randomized controlled trial of the electronic version of the Chinese SF-36 / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVES</b>to verify the feasibility and reliability of the electronic version of Chinese SF-36 based on the Quality-of-Life-Recorder.</p><p><b>DESIGN</b>A crossover randomized controlled trial, comparing a paper-based and an electronic version of the Chinese SF-36, was conducted. According to generated random numbers, interviewees were asked to fill out either the electronic version or the paper version first. The second version was filled in after a pause of at least 10 min.</p><p><b>SETTINGS AND PARTICIPANTS</b>One group of 100 medical students at the School of Medicine of Zhejiang University and the other group of 50 outpatients at a clinic for general practice in Hangzhou City (China) were eventually recruited in this study.</p><p><b>RESULTS</b>The acceptance of the electronic version was good (60% of medical students and 84% of outpatients preferred the electronic version). At the level of eight-scale scores, the mean-difference for each scale (except for general health) between the two versions was less than 5%. At the level of 36 questions, the percentage of "exact agreement" ranged within 64%-99%; the percentage of "global agreement" ranged within 72%-99%; 77% of the kappa coefficients demonstrated "good/excellent agreement" and 23% of the kappa coefficients demonstrated "medium agreement".</p><p><b>CONCLUSION</b>This study, for the first time, can provide empirical basis for the confirmation of the feasibility and reliability of the electronic version of the Chinese SF-36 and may provide an impulse towards widespread deployment of the Quality-of-Life-Recorder in Chinese populations.</p>

Evaluation of the "Jiangsu/WHO 100% condom use programme in China" / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the effect and to explore the feasible model of 100% condom use programme (100%CUP) under existing policy and law milieu, so as to provide information for the adjustment of HIV/AIDS policy and intervention strategies.</p><p><b>METHODS</b>Information on knowledge, attitude and behavior of female sex workers (FSWs) in entertainment establishments were collected and followed by qualitative and quantitative analysis including: samples tested for Chlamydia; a repeated cross-investigation and the final evaluation on the effect of the programme.</p><p><b>RESULTS</b>The reported rate of condom use at the last sex activity with clients increased from 74.9% to 92.2% while the rate of sexually transmitted disease (STD) prevalence droped from 25.1% to 14.1% after three year's intervention program. The number of condoms distributed increased from 50,000 per quarter of a year in 2001 to over 100,000 in 2003. The rates of awareness on the knowledge of STD/AIDS prevention increased obviously.</p><p><b>CONCLUSION</b>The 100%CUP was proved to be feasible and effective in the pilot site, and should be expanded in entertainment establishments.</p>
