RESUMO
BACKGROUND: Given the limitation of pharmacological treatments to treat cognitive symptoms in patients with Major Depressive Disorder (MDD), cognitive remediation programs has been proposed as a possible procognitive intervention but findings are not conclusive. This study investigates the efficacy of an INtegral Cognitive REMediation (INCREM) that includes a combination of a Functional Remediation (FR) strategy plus a Computerized Cognitive Training (CCT) in order to improve not only cognitive performance but also the psychosocial functioning and the quality of life. METHODS: A single blind randomized controlled clinical trial in 81 patients with a diagnosis of MDD in clinical remission or in partial remission. Participants will be randomized to one of three conditions: INCREM (FR + CCT), Psychoeducation plus online games and Treatment As Usual (TAU). Intervention will consist in 12 group sessions, of approximately 110 min once a week. The primary outcome measure will be % of change in psychosocial functioning after treatment measured by the Functional Assessment Short Test (FAST); additionally, number of sick leaves and daily activities will also be recorded as pragmatic outcomes. DISCUSSION: To our knowledge, this is the first randomized controlled clinical trial using a combination of two different approaches (FR + CCT) to treat the present cognitive deficits and to promote their improvements into a better psychosocial functioning. TRIAL REGISTRATION: Clinical Trials NCT03624621 . Date registered 10th of August 2018 and last updated 24th August 2018.

BACKGROUND: Despite achieving clinical remission, patients with depression encounter difficulties to return to their premorbid psychosocial functioning. Cognitive dysfunction has been proposed to be a primary mediator of functional impairment. Therefore, the new non-pharmacological procognitive strategy INtegral Cognitive REMediation for Depression (INCREM) has been developed with the aim of targeting cognitive and psychosocial functioning. METHODS: This is a single-blind randomized controlled clinical trial with three treatment arms. Fifty-two depressed patients in clinical remission, with psychosocial difficulties and cognitive impairment, were randomly assigned to receive INCREM intervention, Psychoeducation programme, or treatment as usual. Patients were assessed before and after the study period, and six months after. The primary outcome was the change from baseline of patients' psychosocial functioning. Changes in cognitive functioning and other variables were considered secondary outcomes. RESULTS: The analysis showed a significant improvement in psychosocial functioning in the INCREM group, especially six months after the intervention, compared to patients who received the psychoeducation programme. An improvement in cognitive performance was also observed in the INCREM group. LIMITATIONS: This study includes a small sample size due to the anticipated end of the clinical trial because of the COVID-19 pandemic. DISCUSSION: These results provide preliminary evidence on the feasibility and potential efficacy of the INCREM program to improve not only cognitive performance but also psychosocial functioning in clinically remitted depressed patients, and such improvement is maintained six months after. It can be speculated that the maintenance is mediated by the cognitive enhancement achieved with INCREM.

Although pharmacotherapy is considered the first-line treatment for bipolar disorders (BD), adjunctive psychoeducation has proven its effectiveness in improving self-management of the disease and reducing relapse rates. Few studies have evaluated the effect of brief group psychoeducation on pragmatic variables, such as the number of hospitalizations. The aim of the present study was to assess the mid-term effect of a four-session group psychoeducation on course-related variables in BD. Thirty-two individuals with BD were included in the study. Sixteen were exposed to psychoeducation and were matched to sixteen nonexposed individuals who received their usual treatment. Both groups were compared on insight, treatment adherence, change in the number of hospitalizations and visits to the emergency services, occurrence rate after intervention, and time to the first psychiatric hospitalization and the first urgent attendance. There was a significant reduction in the mean number of hospitalizations and urgent attendances in the exposed group in comparison to the nonexposed group. The first urgent attendance was significantly sooner in the nonexposed cohort. There were no differences between groups in any of the other variables. This intervention has shown benefits for pragmatic variables of the disease course and may be a feasible and cost-effective intervention to routinely implement in the management of BD.
