Background: Studies show the effectiveness of group psychoeducation in reducing symptoms in people with depression. However, few controlled studies that have included aspects of personal care and healthy lifestyle (diet, physical exercise, sleep) together with cognitive-behavioral techniques in psychoeducation are proven to be effective.The objective of this study is to assess the effectiveness of a psychoeducational program, which includes aspects of personal care and healthy lifestyle, in patients with mild/moderate depression symptoms in Primary Care (PC).Methods: In a randomized, controlled trial, 246 participants over 20 years old with ICD-10 major depression were recruited through nurses/general practitioners at 12 urban Primary Care Centers (PCCs) in Barcelona. The intervention group (IG) (n=119) received a group psychoeducational program (12 weekly, 1.5 h sessions led by two nurses) and the control group (CG) (n=112) received usual care. Patients were assessed at baseline and at, 3, 6 and 9 months. The main outcome measures were the BDI, EQ-5D and remission based upon the BDI.Results: 231 randomized patients were included, of whom 85 had mild depression and 146 moderate depression. The analyses showed significant differences between groups in relation to remission of symptoms, especially in the mild depression group with a high rate of 57% (p=0.009) at post-treatment and 65% (p=0.006) at 9 month follow up, and only showed significant differences on the BDI at post-treatment (p=0.016; effect size Cohen's d'=.51) and at 6 and 9 month follow-up (p= 0.048; d'=.44).In the overall and moderate sample, the analyses only showed significant differences between groups on the BDI at post-treatment, p=0.02 (d'=.29) and p=0.010 (d'=.47), respectively.The psychoeducation group improved significantly on the EQ-5D at short and long-term.Conclusions: This psychoeducational intervention is a short and long-term effective treatment for patients with mild depression symptoms. It results in a high remission rate, is recommended in PC and can be carried out by nurses with previous training. In moderate patients, group psychoeducation is effective in the short-term.Trial registration: Clinical Trials.gov identifier NCT00841737. © 2012 Casanas et al.; licensee BioMed Central Ltd.

Background. There is evidence supporting the effectiveness of psychoeducation (PE) in patients with symptoms of depression in primary care (PC), but very few studies have assessed this intervention in antidepressant-naïve patients. The aim of this study is to assess the effectiveness of a PE program in these patients, since the use of antidepressant (AD) medication may interfere with the effects of the intervention. Methods. 106 participants were included, 50 from the PE program (12 weekly 1.5-hour sessions) and 56 from the control group (CG) that received the usual care. Patients were assessed at baseline and at 3, 6, and 9 months. The main outcome measures were the Beck Depression Inventory (BDI) and remission based on the BDI. The analysis was carried out on an intention-to-treat basis. Results. The PE program group showed remission of symptoms of 40% (P = 0.001) posttreatment and 42% (P = 0.012) at 6 months. The analysis only showed significant differences in the BDI score posttreatment (P = 0.008; effect size Cohen's d ′ = 0.55). Conclusions. The PE intervention is an effective treatment in the depressive population not treated with AD medication. Before taking an AD, psychoeducational intervention should be considered. © 2015 R.

Although working memory is known to be impaired in schizophrenia the anatomical and functional relationships underlying this deficit remain to be elucidated. A combined imaging approach involving functional and structural magnetic resonance techniques was used, applying independent component analysis and surface-based morphometry to 14 patients with schizophrenia and 14 healthy controls. Neurocognitive functioning was assessed by a neuropsychological test battery that measured executive function. It was hypothesized that working memory dysfunctional connectivity in schizophrenia is related to underlying anatomical abnormalities. Patients with schizophrenia showed cortical thinning in the left inferior frontal gyrus and insula, which explained 57% of blood oxygenation level-dependent signal magnitude in functional magnetic resonance imaging in the central executive network (lateral prefrontal and parietal cortex) over-activation and default mode network (anterior and posterior cingulate) deactivation. No structure-function relationship emerged in the healthy control group. The study provides evidence to suggest that dysfunctional activation/deactivation patterns in schizophrenia may be explained in terms of underlying gray matter deficits. © 2013 Elsevier Ireland Ltd.

While the role of impaired neurocognition in accounting for functional outcome in schizophrenia is generally established, the influence of social cognition on this relationship is far from clear. This study aims to explore in depth the nature of the relationship between neurocognition, social cognition and daily functioning in people with schizophrenia. Twenty-one individuals diagnosed with schizophrenia and 15 controls completed the assessment of symptom severity, neuropsychological status, social cognition (Theory of Mind and affect processing) and other functional measures. A statistical mediation model based on hierarchical regression analyses was used to establish the mediation path with significant variables. Social cognition played a mediating role between neurocognition and functioning, accounting for significant trends in incremental variance in specific functional indexes (interpersonal behavior and employment/occupation). Consequently, this study adds to the evidence underlining the importance of targeting not only social cognitive or neurocognitive functions but to combine both interventions to reveal the best daily functioning results in schizophrenia patients. © 2014 Elsevier Ireland Ltd.
