Objective: To describe the development of weCope, a Portuguese mobile app for people with schizophrenia. Methods: The development of weCope followed 4 stages: I-102 people with psychotic disorders completed an online questionnaire; II-a multidisciplinary focus group was conducted among five mental health professionals; III-we developed the app; IV-9 participants used weCope during 8 weeks to assess its efficiency. Results: weCope targets coping with voices, problem solving, goals setting and stress management, and results indicated that: weCope improved symptoms, sense of recovery and personal and social functioning; 59% of the participants were willing to download an application for illness self-management; professionals revealed some concerns about mHealth but enhanced the high importance to develop these apps; usability testing revealed that 89% considered weCope useful for illness self-management. However, the more years with mental illness, the less importance is given to a mobile application for this purpose. Discussion: weCope was developed through a comprehensive development process and may contribute to a subjective perception of the patient's better well-being and health condition.

There is an urgent need to develop more effective interventions for psychotic disorders. Mobile Health solutions can address this emerging problem but needs more research. This study aims to present a new intervention and have some preliminary data about weCOPE. The sample is constituted by nine participants with a mean age of 38 years (±9.701), being 78% men, and with mean clinical follow-up time of 10 years. The intervention lasted eight weeks and was followed by each user's case manager. The data collection was carried out in two moments (before and after the application use), using six evaluation instruments: Recovery Assessment Scale, Empowerment Scale, General Self-Efficacy Scale, Social Support Satisfaction Scale, Personal and Social Performance Scale, and Positive and Negative Syndrome Scale. The data collected through these instruments were analyzed later through descriptive and inferential statistics. The majority of the results were significant and indicate that weCOPE may produce an improvement in symptoms (general psychopathology), empowerment, recovery, satisfaction with social support, self-efficacy, and personal and social functioning. Thus, this kind of mobile technologies for schizophrenia selfmanagement may contribute to a subjective perception of the patient's better well-being and health condition.
