[Adaptation and validation of a brief screening questionnaire of depressive disorders in patients with cancer: Q2i study].

Background: Depression is a sustainable state of deep sadness and abatement. It is frequently identified in patients with cancer and often undervalued by oncologists. The reduced PRIME-MD questionnaire is a questionnaire of 2 items validated in French. However, it has been neither translated nor validated in French. The objective of our study is to translate the PRIME-MD and validate it into French.

Method: The PRIME-MD questionnaire was translated into French by using the recommendations of the EORTC and compared to the French gold standard questionnaire Mini-International Neuropsychiatric Interview (MINI).

Results: Two hundred and ninety-nine patients were included in our study. With a 98% filling rate, the Q2i questionnaire has been well accepted. The prevalence of depression in our population was measured at 7.4%. With a sensitivity of 89.47%, a specificity of 58.85%, found percentages are equal to those of the questionnaire in English. The negative predictive value was measured at 98.52%.

Conclusion: This study demonstrates that the Q2i questionnaire is a quick and easy screening tool, requiring less than 2minutes to target patients likely to benefit from psychological support.
