Depression is one of the most common mental disorders in older adults and a major cause of years lived with disability. Depression does not always respond to antidepressants, and non-pharmacological interventions are recommended by international guidelines. The Metacognitive Training for Depression in Later Life (MCT-Silver) is a creative and innovative group intervention that aims to reduce depressive symptoms by challenging the cognitive and metacognitive beliefs characteristic of this disorder, that intends to enable participants to recognize and correct their automatic and dysfunctional thinking patterns and behavior. It was developed by the partner institution's team, and has already demonstrated positive results. This project aims to extend the research study to Portugal, through cultural adaptation, pilot study, and a Randomized Controlled Trial (RCT). To this end, we defined the following aims: To plan and conduct a pilot study to assess the efficacy of the MCT-Silver in the Portuguese population; To conduct a multicenter randomized controlled trial (RCT).

MCT-Silver consists of eight modules, each of which begins with psychoeducational and "normalizing" elements. A mastery is presented through examples and exercises, and the fallibility of human cognition is discussed and illustrated. In a second phase, the pathological extremes of each cognitive bias are highlighted and the participant is shown how the exacerbation of (normal) thinking biases can lead to problems in daily life. It is intended with this exercise that participants learn how to identify and mitigate cognitive "traps". Dysfunctional coping strategies (social isolation and negative thoughts) are highlighted, and suggestions for replacing them with adaptive strategies are given. Homework assignments are distributed at the end of each session (Schneider et al., 2018).

RECRUITINGHamilton Depression Rating Scale (HRSD-24)
The 24-item version of the Hamilton Depression Rating Scale is an established clinician-rated assessment of depressive symptom severity and assesses psychological as well as somatic symptoms (scores range from 0-2 or 0-4) of depression. The clinician rates the severity of these symptoms based on the patient's report and his or her own observation. Scores range from 0-54. Based on the first 17 items, a score of 8-13 indicates mild depression, 14-18 indicates moderate depression, 19-22 indicates severe depression and scores greater than 23 indicate very severe depression. The scale has demonstrated good sensitivity and specificity among older adults (Mottram, Wilson \& Copeland, 2001). The reliability and validity among older adult samples has also been confirmed (Korner et al., 2006). In terms of assessing change for the current trial, a greater reduction in depressive symptoms (i.e., change score) indicates better outcome.

Time frame: Follow-up (6 months after the intervention)
Patient Health Questionnaire 9 (PHQ-9)
9-item scale developed to assess depressive symptoms and to evaluate the symptoms of depression.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Beck-Depressions-Inventar II (BDI-II)
Change in self-assessed depression as measured by the Beck Depression Inventory (BDI) total score from baseline to post-assessment (8 weeks) and baseline to follow-up (5 months). The BDI is a 21-item self-report measure of depression symptoms. Total scores range from 0-63 with higher scores indicating more severe levels of depression.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Mini Mental State Examination (MMSE)
Developed by Folstein et al, 1975 to assess cognitive deficits.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Dysfunctional Attitudes Scale Form 18B (DAS-18B)
Change in dysfunctional attitudes as measured by change in the Dysfunctional Attitudes Scale Form 18B (DAS-18B) total score and subscale scores from baseline to post-assessment (8 weeks) and baseline to follow-up (5 months). Each item is endorsed on a 7-point scale (Range: 0-7) such that a total score of 126 is possible with higher scores indicating dysfunctional beliefs which are held more strongly. The total score is comprised of two subscales (perfectionism (Range 0-56); need for social approval (Range 0-21)), which are summed along with 7 other items to calculate the total scale score.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Metacognitions Questionnaire (MCQ-30)
Change in metacognitive beliefs as measured by change in the Metacognitions Questionnaire (MCQ-30) total score and subscale scores from baseline to post-assessment (8 weeks) and baseline to follow-up (5 months). The 30-item scale has a range of 30-120. The scale is comprised of five subscales (range for each = 6-24): (1) Positive Beliefs (PB) about worry (6 items); (2) Negative Beliefs (NB) about thoughts concerning uncontrollability and danger (6 items), and (3) beliefs about the need to control thoughts (Need for Control \[NFC\],6 items); (4) Cognitive Confidence (6 items) and Cognitive Self-Consciousness (6 items). Higher scores indicate more strongly held metacognitive beliefs.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Rosenberg Self-Esteem Scale
Change in self-esteem as measured by change in the Rosenberg Self-Esteem scale total score from baseline to post-assessment (8 weeks) and baseline to follow-up (5 months). The scale is comprised of 10 items and scores range from 10-40 with higher scores indicating higher self-esteem.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Ruminative Responses Scale
Change in rumination as measured by the Ruminative Responses Scale total score from baseline to post-assessment (8 weeks) and baseline to follow-up (5 months). The scale is comprised of 10 items and scores range from 10-40 with higher scores indicating higher self-esteem.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
Attitudes to Ageing Questionnaire (AAQ)
The attitudes to ageing questionnaire (AAQ) \[12\] was developed to provide a standard way of measuring attitudes to ageing from the perspective of older people.
Time frame: Total Time Frame is 7 months. Outcome is assessed at three points: baseline; post-intervention and Follow-up (6 months after the intervention)]
ICF Core Set for Depression
was developed through the WHO International Classification of Functioning, Disability and Health (Cieza et al., 2004), and criteria are being developed to make the assessment more objective, through the modified e-Delphi technique.
