Unfortunately, there is a high percentage of undetected cases, due to underdiagnosis or overdiagnosis. An incorrect identification of these disorders leads to inaccurate referrals; 39% receive no treatment and only one in three patients treated follow a minimally evidence-based treatment. In the PsicAP clinical trial, the psychometric properties of the Patient Health Questionnaire (PHQ), its different modules of anxiety (GAD-7), depression (PHQ-9) and panic disorder (PHQ-PD), and an ultra-brief version derived from the PHQ for anxiety and depression (PHQ-4) have been analysed. A diagnostic and referral hierarchical model of common mental disorders is proposed based on the validation of these instruments among patients attending Spanish PC centres.  a1134-7937
