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.
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.
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 > or =14 for the K10 and between > or =9 and > or =11 for the K6 for identifying women at high risk of depression. At > or =14, the K10 has 59% sensitivity, 91% specificity; at > or =10, the K6 has 59% sensitivity and 85% specificity.
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.
K10和K6是简短的评定量表，旨在检测有或无焦虑的抑郁症风险个体。尽管被广泛使用，但它们尚未经过检测产后抑郁症的验证。我们描述了这些量表在布基纳法索检测产后抑郁症的有效性。
K10问卷的英文版本被翻译成西非法语和当地语言，用于布基纳法索。将61名女性的得分与当地精神科医生在实施K10后3天内进行的诊断访谈结果进行比较。
临床评估发现，27名（44%）女性可能患有抑郁症。由克朗巴哈α系数定义的K10和K6得分的内部一致性分别为0.87和0.78，表明可靠性令人满意。得分的表现没有显著差异，K10和K6的曲线下面积分别为0.77和0.75。为了估计抑郁症的患病率，我们建议K10的临界值为≥14，K6的临界值在≥9和≥11之间，以识别抑郁症高风险女性。在≥14时，K10的灵敏度为59%，特异度为91%；在≥10时，K6的灵敏度为59%，特异度为85%。
本研究表明，K10和K6是布基纳法索产后女性抑郁症的合理有效测量方法，可作为发展中国家估计产后抑郁症患病率的相对廉价工具。
