目的K10和K6是一种短量表，用于检测有或无焦虑抑郁障碍风险的个体。尽管它们被广泛使用，但尚未被证实用于检测产后抑郁症。我们描述了这些量表在布基纳法索产后抑郁症检测的有效性。方法将K10问卷的英文版本翻译成西非法语和当地语言，供布基纳法索使用。61名妇女的得分与当地精神科医生在给予K10后3天内进行的诊断性访谈进行比较。结果临床评估发现27例（44%）女性为可能的抑郁症病例。以Cronbach’s alpha系数定义的K10和K6评分的内部一致性分别为0.87和0.78，信度令人满意。K10和K6的得分表现无显著差异，曲线下面积分别为0.77和0.75。为了估计抑郁症的患病率，我们建议在K10的临界值为>= 14，在K6的临界值为>= 9和>= 11之间，以确定抑郁症的高风险女性。在>= 14时，K10的敏感性为59%，特异性为91%；在>= 10时，K6的敏感性为59%，特异性为85%。结论本研究表明，K10和K6是布基纳法索产后妇女抑郁的合理有效的测量方法，可以作为估计发展中国家产后抑郁患病率的相对廉价的工具。
OBJECTIVE The K10 and K6 are short rating scales designed to detect individuals at risk for depressive disorder, with or without anxiety. Despite being widely used, they have not yet been validated for detecting postnatal depression. We describe the validity of these scales for the detection of postnatal depression in Burkina Faso.METHOD The English language version of the K10 questionnaire was translated into West African French and local languages for use in Burkina Faso. Scores for 61 women were compared with the diagnostic interview made by a local psychiatrist within 3 days of administering the K10.RESULTS Clinical assessment found that 27 (44%) women were probable cases of depression. Internal consistency of K10 and K6 scores, defined by Cronbach's alpha coefficient, was 0.87 and 0.78, respectively, indicating satisfactory reliability. The performance of the scores was not significantly different, with areas under the curve of 0.77 and 0.75 for the K10 and K6, respectively. To estimate prevalence of depression, we suggest cut-offs of >= 14 for the K10 and between >= 9 and >= 11 for the K6 for identifying women at high risk of depression. At >= 14, the K10 has 59% sensitivity, 91% specificity; at >= 10, the K6 has 59% sensitivity and 85% specificity.CONCLUSION This study suggests that K10 and K6 are reasonably valid measures of depression among postpartum women in Burkina Faso and can be used as relatively cheap tools for estimating prevalence of postnatal depression in developing countries.
