The objective of this study was to design and develop the Perception Scale of Barriers to Contraceptive Use (PSBCU) as a measurement tool for the qualitative assessment of the barriers and obstacles women perceived with regard to contraceptive use or low rates of contraceptive use in women using family planning services.
The data for this methodological study were collected using the face-to-face interview technique from 320 married women between the ages of 15-49 who were attending clinics at the Hafsa Sultan Hospital, CBU. The data collection tools used in the study, which was carried out from May to September 2014, were the "Introductory Information Form" and the "Perception Scale of Barriers to Contraceptive Use". Language validity and construct validity (explanatory factor analysis) were applied in order to test the validity of the Perception Scale of Barriers to Contraceptive Use.
Kaiser Meier Olkin (KMO) analysis was performed to determine the availability of the scale for the size of participants. The sample adequacy calculated as the KMO value was 0.916 and the Bartlett's Test of Sphericity (X = 6721.793 < 0.000) sample size analysis value was found to be sufficient for factor analysis. The total Cronbach's Alpha coefficient of 34 items which included three factors explaining 54.95% of the variance after Varimax rotation was calculated to be 0.95. The largest factor was the "cognitive domain" explaining 18.89% of the variance, followed by the "emotional domain" explaining 18.05% of the variance, and finally the "social domain" explaining 18.01% of the variance. Item-total score correlation coefficients of scale items were found to be between 0.54 and 0.83.
The study demonstrateded that the "Perception Scale of Barriers to Contraceptive Use" was valid and reliable. We believe that the scale is suitable for use by women in a family planning education and training programs in order to evaluate their situation. It should also be assessed for validity and reliability for different groups (adolescents, men, etc.).
本研究的目的是设计并开发避孕使用障碍感知量表（PSBCU），作为一种测量工具，用于定性评估女性在使用计划生育服务时对避孕使用或低避孕使用率所感知到的障碍和阻碍。
本方法学研究的数据通过面对面访谈技术，从320名年龄在15 - 49岁之间、在恰纳卡莱布伦大学哈夫萨·苏丹医院诊所就诊的已婚女性中收集。2014年5月至9月进行的该研究中使用的数据收集工具为“基本信息表”和“避孕使用障碍感知量表”。为检验避孕使用障碍感知量表的有效性，应用了语言效度和结构效度（解释性因素分析）。
进行了凯泽 - 迈耶 - 奥尔金（KMO）分析，以确定该量表对于参与者规模的适用性。计算得出的作为KMO值的样本充足性为0.916，巴特利特球形检验（X = 6721.793 < 0.000）样本量分析值被发现足以进行因素分析。在方差最大化旋转后，包括解释54.95%方差的三个因素的34个条目的总克朗巴哈系数计算为0.95。最大的因素是“认知领域”，解释了18.89%的方差，其次是“情感领域”，解释了18.05%的方差，最后是“社会领域”，解释了18.01%的方差。量表条目的项目 - 总分相关系数在0.54至0.83之间。
该研究表明“避孕使用障碍感知量表”是有效且可靠的。我们认为该量表适用于计划生育教育和培训项目中的女性，以评估她们的情况。对于不同群体（青少年、男性等），也应评估其效度和信度。
