To assess the extent to which family physicians (FPs) involve women in decisions about prenatal screening for Down syndrome.
Based on transcripts of consultations between 41 FPs and 128 women, two raters independently assessed clinician's efforts to involve women in decisions about prenatal screening for Down syndrome using the French-language version of OPTION. Descriptive statistics of OPTION scores were calculated. Construct validity was assessed by performing a principal factor analysis and by measuring association with consultation duration and FPs sociodemograhics. Internal consistency was assessed with Cronbach's alpha and inter-rater reliability with the intraclass correlation coefficient.
The overall mean OPTION score was low: 19 +/- 7 (range = 0 [no involvement] to 100 [high involvement]). One factor accounted for 80% of the variance. Both internal consistency and inter-rater reliability were very good (Cronbach's alpha = 0.73; ICC = 0.76). OPTION scores were lower for residents than for licensed FPs (17 +/- 5 vs 21 +/- 4; p = 0.02) and were positively associated with duration of consultation (r = 0.56; p < 0.001).
Based on the French-language version of OPTION, which showed satisfactory psychometric properties, FPs studied put minimal efforts to involve women in decisions about prenatal screening for Down syndrome.
评估家庭医生(FP)在多大程度上让女性参与唐氏综合征产前筛查决策。
基于 41 名 FP 和 128 名女性咨询的转录本,两名评估员使用 OPTION 的法语版本独立评估临床医生在参与唐氏综合征产前筛查决策方面的努力。计算 OPTION 评分的描述性统计数据。通过进行主成分分析和测量与咨询时间和 FP 社会人口统计学的关联来评估结构有效性。使用 Cronbach's alpha 评估内部一致性,使用组内相关系数评估组内一致性。
总体平均 OPTION 得分为低:19 +/- 7(范围为 0 [无参与]至 100 [高参与])。一个因素占方差的 80%。内部一致性和组内一致性都非常好(Cronbach's alpha = 0.73;ICC = 0.76)。住院医师的 OPTION 评分低于持照 FP(17 +/- 5 与 21 +/- 4;p = 0.02),与咨询时间呈正相关(r = 0.56;p < 0.001)。
基于 OPTION 的法语版本,其表现出令人满意的心理测量特性,研究中的 FP 仅在最小程度上努力让女性参与唐氏综合征产前筛查决策。
