This project is aimed at responding to one of the Challenges of the Spanish Strategy for Science, Technology and Innovation, specifically Challenge 1: Health, demographic change and well-being. One of the work areas that are located within this challenge is the Clinical and Translational Research based on the evidence of scientific and technological knowledge.The present proposal is clearly within the framework of clinical-translational investigation, since most of the entities participating attend persons with psychotic disorders, thereby ensuring the translation of investigation to the clinical setting. In addition, this project includes investigators with wide experience in psychological interventions in the target population and with previous experience in investigation in this area. Lastly, it is of note that the benefits of this investigation are not only of a scientific nature but also involve clinical investigation with a direct repercussion on improvement in the health care of people with psychotic disorders, enabling the design of new strategies of psychological interventions. Besides, the present proposal is aimed at responding to the challenges of our society, contributing to covering the needs of persons with psychotic disorder as well as developing the most effective therapeutic strategies to improve aspects related to clinical and personal recovery. Specifically, this project will allow making changes that will improve the quality of health care to the target population incorporating the combinated use of scientifically proven therapeutic strategies to health care services. In short, this project aims to promote innovation in the provision of mental health services, being the starting point in analyzing the efficacy of combined psychological therapies versus monotherapies address to improve of metacognitive processes.
- General and specific objectives. General objective: Compare the efficacy of combined REHACOP + MCT therapy vs. MCT alone in persons with nonaffective psychotic disorder in terms of recovery.
Specific objectives:
Design:
This will be a randomised clinical trial in which one group will receive combined REHACOP + MCT therapy and another group will receive therapy with MCT alone. The metacognitive treatment will have the same characteristics in the two treatment conditions. Randomisation of the patients for receiving one of the two treatments will be carried out using a random number list based on the order of access to their reference centre. The evaluator will be blinded to the treatment group to which the patient assessed belongs.
Study subjects: The sample will be made up of people with non-affective psychotic disorder who are attended in any of the centres participating in the study which belong to the following entities:Consorci Sanitari de Terrassa; Hospital de Mataró; Instituto de Investigación Biomédica de Gerona (IdIBG); Parc Sanitari Sant Joan de Déu; Asociación Centro de Higiene Mental Les Corts; Hospital Sierrallana-Tres Mares; and UGC Salud Mental de Jaén.
Sample size: Considering that the investigators have no preliminary data on our principal objective in relation to clinical and personal recovery, the score obtained in the global assessment of functioning (GAF) at follow-up will be taken as a measure of outcome, since it is implicated in both clinical and functional recovery. The investigators used the data published in the article by Ochoa et al. (2017) in order to calculate the required sample size for this study. In this article, a difference of means of 5.73 points (SD=11.51) is obtained in the GAF scale from baseline and the follow-up at 6 months after the intervention. With these data, the necessary sample size has been estimated with an alpha of 0.05 and a power of 0.8. Taking into account 20% of possible losses to follow-up, the sample size has been calculated as 160 cases, 80 in each experimental arm (REHACOP + MCT vs. MCT). In this way, taking into account that the intervention groups will be carried out in the health care centers of 7 different entities each will have to recruit 24 patients, 12 for each experimental condition.
Data collection: the professional who makes the referral of the patients to the study will be responsible for reviewing fulfillment of the inclusion and exclusion criteria. Patients fulfilling the inclusion criteria will receive an explanation of the study and if they accept to participate, they must provide signed informed consent. The evaluation will be carried out at 3 time points: T0 (basal assessment, prior to initiation of treatment). All the previously described scales will be administered; T1 (post-treatment evaluation), all the scales will be administered and, in addition, the satisfaction perceived with the interventions received will be evaluated; T2 (follow-up evaluation ) at 6 months after completing the intervention all the scales will again be administered. In addition, the number of relapses and hospitalizations during the time interval will be registered. Assessment of the PANSS and GAF should take into account the temporal criterium mentioned in the section of 'Outcomes'. A contingency plan will be considered in the event that difficulties are detected in carrying out any of the phases of the study due to external causes, such as the continuity of the COVID-19 pandemic. This plan will consist of the implementation of interventions and evaluations making use of new technologies. All the centers already have the adequate infrastructure to carry out the project under these conditions.
Data analysis: Firstly, the two groups will be compared with the aim of verifying that there are no significant differences at baseline to confirm that they are comparable after randomization. Comparisons of means for independent samples will be carried out using the Student's t-test for continuous variables and the Chi-square test for categorical variables. The variables of the principal analysis will be the difference between the scores of the two groups (REHACOP+MCT and MCT) in the scores of the scales assessing clinical and personal/psychological recovery. The secondary results will be the differences in other assessments of social functioning, cognitive biases, and social cognition on comparing the two experimental conditions. Changes in the scores of these scales will be analyzed using regression methods for repeated measures, with the post-treatment score of the scales as the dependent variable and the basal score and the REHACOP+MCT group as the co-variables. Temporal stability of the results at 6 months will be assessed using the follow-up score as the dependent variable and evaluating how this affects the basal score, post treatment and the experimental condition. The statistical analyses will be performed according to intention to treat (ITT) without imputing the lost values. Gender, antipsychotic medication, and disease evolution time will be considered as control variables.
Limitations:
One of the limitations of this clinical trial might be the loss to follow-up. To compensate for these losses the sample size will be increased by 20%. It is expected that the losses to follow-up will be similar in the two groups. Otherwise, this variable will be considered as an indicator of the acceptability of treatment.

Behavioral: Metacognitive Training (MCT)
REHACOP is a structured neuropsychological rehabilitation program that covers most of the cognitive deficits present in psychotic disorder: attention, learning and memory, executive functions, language, social cognition, daily life activities, social skills and psychoeducation. The modules of language, social cognition and psychoeducation will not be used in the present clinical trial. Each module includes a hierarchy of exercises based on the cognitive subarea to be worked on and the grade of difficulty demanded for the performance of each task.The format of the sessions will be the same as MCT, that is, groups of 6-10 patients who will receive weekly sessions of 45-60 minutes in length. In this case, the duration of the intervention will be 12 sessions.
The MCT consists in 8 weekly sessions of 45-60 minutes in length. Each group of patients should be made up of 6-10 patients. The material of the training program is available online at: http://www.uke.de/mkt. The material contains 16 powerpoint presentations (2 per each module), one manual and 6 pamphlets of tasks to do at home. The modules are as follows: Module 1: Attribution; Module 2: Jumping to conclusions (1st part); Module 3: Changing beliefs; Module 4: To emphatise (1st part); Module 5: Memory; Module 6: To emphatise (2nd part); Module 7: Jumping to conclusions (2nd part); and Module 8: Self-esteem and mood.
