Objective: To design and validate an instrument to assess the level of knowledge of major depression in general practitioners in Chiclayo. Methods: A descriptive, cross sectional study for instrument validation. The first construct was developed in the year 2010 based on the theoretical framework and was subject to expert judgment. During the year 2011, the questionnaire was subjected again to 12 experts according to the Delphi methodology, yielding a construct of 14 questions: 7 for diagnosis and 7 for treatment. A pilot study was conducted to evaluate the relevance and understandability of the instrument The reliability of the instrument was evaluated with the Kuder-Richardson coefficient and the Cronbach’s Alpha. Construct validity was performed by factorial analysis. We used the statistical software SPSS v. 15. Results: We interviewed 34 general practitioners (90%) and 6 students (10%) who had completed the courses of Mental Health: 36 (90%) were male and the mean age was 37.5 ± 15 years. The percentiles 25, 50 and 75 of the total score of the instrument were: 4, 6 and 9, respectively. The Kuder-Richardson coefficient was 0.62, the Cronbach’s alpha for each questions was greater than 0.55. The Kaiser Meyer Olkin test and Bartlett’s sphericity showed that the instrument was one-dimensional. Conclusions: We obtained a valid, reliable and one-dimensional instrument to determine the level of knowledge of major depression in general practitioners.
