Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide. The symptoms cause clinically signifcant distress or impairment in social, occupational, or other important areas of functioning. The episode is not attributable to the physiological efects of a substance or to another medical condition. Although such symptoms may be understandable or considered appropriate to the loss, the presence of a major depressive episode in addition to the normal response to a signifcant loss should also be carefully considered. This decision inevitably requires the exercise of clinical judgment based on the individuals history and the cultural norms for the expression of distress in the contest of loss.

University Center for Psychological Services and ResearchInstitute for Psychological Research University of Puerto Rico, Ro Piedras 2007 Based on the Group Therapy Manual for Cognitive-behavioral Treatment of Depression Ricardo F. Muoz, Sergio Aguilar-Gaxiola, John Guzmn, Jeannette Rossell & Guillermo Bernal. The original manual consisted of a group intervention model for adults with depression. This intervention was used with adult Hispanic populations in the San Francisco area. The main aims of this intervention are to decrease depressive symptoms, shorten the time the adolescent is depressed, learn new ways to prevent becoming depressed and feel more in control. The original manual was subjected to various changes in order to adapt it for use with Puerto Rican adolescents. To this end, the following changes were made: (1) The group format was adapted to an individual treatment modality. This makes for a more dynamic and interactive therapy, thus allowing the adolescent to assume a more active role. The formal "usted" was substituted for the familiar second person voice "tu" in order to eliminate the interpersonal distance associated with "usted" in a youth population. Therefore, the therapist has two choices: talk about the adolescents thoughts about the assignment, and/or complete the assignment at the beginning of the therapy session. This creates an open session to establish rapport with the adolescent and explore in detail his/her condition. After the original adaptation in the first clinical trial, the manual has continuously been refined based on our experiences with its use with Puerto Rican adolescents. Examples have been added based on real experiences that adolescents have brought up in therapy. More detailed instructions for therapists have been provided to facilitate the use of the techniques described in the manual. We also developed a manual for the participants that summarizes the main points from each session as well as worksheets to be used in-session and in between sessions. Most therapeutic interventions used with adolescents are the result of adaptations of interventions used with adults. Cognitive-behavioral therapy is based on the interrelationship of thoughts, actions, and feelings. In order to work with feelings of depression, this model establishes the importance of identifying the thoughts and actions that influence mood. Therapy sessions are divided into three topics or modules that consist of four sessions each. The initial session establishes the structure and purpose of the subsequent sessions. Also, the time and day of the sessions will be established as well as rules for therapy and limits of confidentiality. It is important that participants are clear on the limits and scope of confidentiality since this can have an effect on the type and quality of the therapeutic relationship. The first session begins a dialogue on depression: what it is and how the participant experiences it. The therapist also presents the purpose of the first module, which is to understand how our thoughts influence our mood. The next three sessions work with different types of thinking errors and dysfunctional thoughts associated with depression, as well as how they can be debated and modified to improve our mood.
