[[alternative]]The effects of health educational intervention on women’s intention and behavior of breast cancer screening

[[abstract]]本實驗型研究(Experimental research)主要探討不同衛教介入措施對婦女乳癌篩檢行為及意向之影響。研究對象來自台北縣某地區40歲以上之國中夜補校婦女，以隨機分派將其分為實驗組Ⅰ(n=31)、實驗組Ⅱ(n=31)及對照組(n=32)進行為期三個月的研究。實驗組Ⅰ採團體衛教，實驗組Ⅱ採團體衛教加提醒法的介入，對照組採事後之衛教。研究工具包括：乳癌及乳癌篩檢知識、健康信念量表、乳癌篩檢意向及行為量表，以專家效度及內部一致性信度建立工具之信效度，量表之Cronbach’s alpha介於0.54~0.86。前測於團體衛教前一週實施，二次後測分別於團體衛教介入後一週及三個月舉行。總共有84人(n=27 vs. n=29 vs. n=28)完成所有資料收集(完成率：87.09﹪vs.93.55﹪vs.87.50﹪)；統計方式包括描述性統計、卡方檢定、獨立樣本t檢定、一方分類變異數分析及廣義估計函數模式(GEE)等方式來進行分析。研究對象平均年齡為52.74(±6.19)歲，大多數曾接受乳癌篩檢相關資訊(45.24-64.29﹪)，不到一半的人曾經有過乳癌篩檢(20.69-44.83%)，初次乳癌篩檢年齡約40.53- 49.83歲，且大多數人表示沒有得到社會支持來做乳癌篩檢。本研究結果顯示，藉由團體衛教的介入能增進婦女的乳癌及乳癌篩檢知識、乳房自我檢查健康信念、乳房攝影檢查健信念及乳房自我檢查行為，若再加入提醒法的策略，更能有效提昇婦女執行乳房自我檢查的規律性及乳房攝影檢查行為意向。未來衛教相關研究，可進一步的探討社會支持對於規律性的乳癌篩檢行為提昇之果效。[[abstract]]The purpose of this research was to explore the effectiveness of different health education intervention programs for breast cancer screening intention and behavior. The participants were selected among women aged 40 and older from three junior high schools’ night division in Taipei county. They were randomly assigned to experimental group I , experimental group Ⅱ and control group. Women in experimental group I group received group health education, women in experimental groupⅡ received group health education and reminder intervention, and Women in control group received post group health education. Research instruments included knowledge of breast cancer and screening, health belief scale, intention of breast cancer screening, and breast cancer screening behavior (Cronbach’s alpha: 0.54~0.86 ) . Data were collected during pre-test (before the group health education intervention), post-test (after the group health education intervention one week), and after-posttest (after the group health education intervention three month). There were 84 women completing all data collection. The collected data were analyzed by descriptive, chi-square, independent samples t-test, One-way ANOVA, Generalized estimating equations with SPSS 11.0 and SAS 9.1 for windows. The average age of participants was about 52.74(±6.19). Most of the participants had ever received the information on breast cancer and screening (45.24-64.29﹪), and less than half of them had the experiment of breast screening(20.69-44.83﹪). The age of first time breast screening was about 40.53-49.83 years old, and most of them indicated thatthey received low social support for breast screening. Overall, the importance of this research results are: group health education can enhance the knowledge of breast cancer and screening, health beliefs in BSE, and health beliefs in mammography and BSE behavior. In addition, reminder strategy can be used effectively to enhance the regularity of BSE behavior and the intention to approach mammography. Any future researches concerning health education should investigate the topic of effectiveness of social support about enhancing regularity of breast cancer screening
