简要总结
The objective of the present project is to study the differential effectiveness of three brief self-applied via the Internet interventions for mild to moderate depression: a global protocol composed of several therapeutic components (psychoeducation, cognitive restructuring, behavioral activation, positive psychology, and relapse prevention), a protocol just based on behavioral activation (BA), and a protocol just based on positive psychology (PP). The purpose is to know the specific contribution of each therapeutic components in the treatment of depression.
详细描述
Depression is one of the most important health problems worldwide, which generates important costs, both from the economic point of view as from the social and personal one. If not properly treated, it may become chronic and therefore interferes significantly in all areas of operation. Hence, one of the most important challenges within this scope is the design of new ways to apply treatments in a way that maximizes its therapeutic efficiency. Information and Communication Technologies (ICTs) have proven their utility as they are very useful in order to provide help to all those in need. It is a field of study very novel which will become more important in the short term. Several internationally renowned research groups have launched self-applied treatment programs through the Internet in order to address this issue. Results obtained so far are consistent and promising, and show these treatments as effective. However, these treatments have different therapeutic components and it is important to identify the specific contribution of each of them. Therefore, the objective of the present project is to study the differential effectiveness of three brief self-applied via the Internet interventions for mild to moderate depression: a global protocol composed of several therapeutic components (psychoeducation, cognitive restructuring, behavioral activation, positive psychology, and relapse prevention), a protocol just based on behavioral activation (BA), and a protocol just based on positive psychology (PP). A minimum of 192 participants diagnosed with mild to moderate depression symptoms will be randomly assigned to one of the three experimental conditions: an Internet-based global protocol composed of several therapeutic components (n=64); a Internet-based protocol based on BA (n=64), and an Internet-based program based on PP (n=64). Our hypothesis is that it is possible to progress and improve in the treatment of depression through intervention strategies applied through the Internet.

结局指标
主要结局
Change in the Beck Depression Inventory II (BDI-II) (Beck, Steer, & Brown, 1996) at pre, post intervention and at 3 and 12 months follow-ups.
时间窗: Up to 12 months
The BDI-II is one of the most widely used questionnaires to evaluate the severity of depression in pharmacological and psychotherapy trials. It consists of 21 items about the different symptoms characterizing the major depression disorder, summed to obtain the total score, which can be a maximum of 63 points. The instrument has good internal consistency (Cronbach's alpha of 0.76 to 0.95) and a test-retest reliability of around 0.8.
