Brief summary
This study proposes continuity in the implementation of a psychological approach program to enhance cognitive reserve (CR) in children, adolescent and young adults, off-springs of patients with schizophrenia or bipolar disorder (Off-SZBP), and first affective and non-affective episodes with three main objectives: to characterize the cognitive reserve in the early stages of the disease, to validate the adaptation of the intervention to first affective and non-affective disorders to assess the effectiveness of the intervention in a longer term.
Detailed description
The study will include a sample of High Genetic Risk-SZBD (HR-SZBD) subjects (N = 60), First Episode Psychotic Patients (FEP) (N = 60) and CC participants (N = 60). All groups will be evaluated with CR scales as well as clinical, neuropsychological, and neuroimaging tests at baseline. The FEP and HR-SZBD groups will then be randomly allocated to a psychological intervention to enhance CR (N = 30 FEP and 30 HR-SZBD) or a support group (N = 30 FEP and 30 HR-SZBD). Once the psychological intervention (3 months) is completed, the FEP and HR-SZBD groups will be re-assessed with the same clinical, neuropsychological, and neuroimaging tests as well as CR scales that were used at baseline. Between the third and twelfth month, follow-up sessions will be conducted to remind the participants of the contents of the intervention. Finally, clinical, CR, neuropsychological and neuroimaging assessments will be completed in the FEP, HR-SZBD and CC groups at 12 months to verify whether the effects of the intervention remain stable over time.
Interventions
BEHAVIORALEnhancing cognitive reserve
The CR enhancement protocol consists of 12 weekly sessions in a group format with audiovisual and technological devices support. All sessions are held separately for parents and children, adolescents and young adults. All material is adapted to different ranges of age. This same protocol will be adapted for patients with a first affective or non-affective episode. Two sessions are about to promote healthy lifestyle by implementing healthy habits, two more sessions about training and practice mindfulness with virtual reality devices, two sessions about improving leisure-time activities, focused on promoting of intellectual and/or cultural activities as leisure time as well as physical exercise, the rest of sessions are about to promote vocational and educational activities, metacognition, social skills, problem-solving techniques and how to detect and act on warning signs, a brief psychoeducative session about the main early warning signs of general psychopathology.
BEHAVIORALSupport therapy
The support control group will have weekly meetings with assistants to talk about the difficulties they had during the week, without receiving a specific intervention.

Masking description
The experimental group will receive 12 weekly sessions (1 per week) of the intervention, which will be conducted by two psychologists blinded to the assessments.
Intervention model description
An experimental randomized controlled clinical study is proposed, which will be rater-blinded and stratified by age, gender and socioeconomic status to assess the efficacy of a new intervention designed to increase CR in FEP and HR-SZBD subjects.

|---|---|---|
| cognitive reserve | 12 months | the enhancing of cognitive reserve by means of the Cognitive Reserve Assessment Scale (CRASH scale). The CRASh scale is an interviewer-administered instrument which consists of 23 items to assess three domains related with the cognitive reserve: education, occupation and leisure and intellectual activities. This last domain will have evaluated taking into account the different life stages (childhood/adolescence, adulthood and current situation). The scale provides a total score and different scores for each specific domain. The maximum total score is 60 points. Each domain scores is calculated by adding all items of the domain. The higher scores, the higher CR level. |
