Aims: 1.To develop and employ computer-based assessment to more accurately and timely detect patient depression in PC settings; 2.To evaluate the feasibility and effectiveness of a care support program developed in conjunction with the PC-based assessment for patients suffering from depression, as based on two main objectives: 2a.To support GP decisions with treatment algorithms and improve the quality of GP and mental health service collaboration; 2b.To improve patient compliance and treatment adherence by using appropriate telecommunication tools and technologically advanced tools to conduct systematic routine assessment. Although much of this system will be computer-based, live telephonic and in-person contacts will also be included as needed.
