The Portuguese version of the PHQ-9 had satisfactory internal consistency (Cronbach's alpha = 0.86) and showed moderate convergent validity with the HADS anxiety (r = 0.61; p &lt; 0.01) and HADS depression (r = 0.59; p &lt; 0.01), and strong convergent validity with the BDI (r = 0.85; p &lt; 0.01).<\/jats:p><\/jats:sec><jats:sec id=\"S0924933800122837_abst0006\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>The PHQ-9 has good psychometric properties amongst Portuguese university students.
