Development and evaluation of the APP and interventions
memory deficits, nutritional deficiencies
DISEASE, PATHOLOGY, NUTRITIONAL DEFICIENCIES
All participants continued with their TAU and were overseen by their PHC professionals and other medical specialists.Participants assigned to the intervention group had access to the APP with rehabilitative content and attended three sessions on motivational methodology, APP management, and strengthening of their personal constructs (health literacy, self-efficacy, and personal activation). Two individual sessions and one group session were held over three consecutive weeks, after completing the baseline assessments and randomization process. The sessions were based on the motivational guide by Miller and RollnickAs for the ReCOVery APP architecture, a native APP was created with Java language, using the Android Studio platform. The design of a native APP was chosen, as opposed to a hybrid one, in order to make use of the device's own tools, such as notifications. This allowed the APP to remain updated. A human-centered design was selected. This technique aims to solve problems and needs by understanding the users themselves. Thus, the initial ReCOVery design was guided by symptoms, identified needs, and other information obtained through individual qualitative interviews and focus group discussions with patients diagnosed with long-term COVID-19All of the details on the creation process, contents, and bibliographical references for the ReCOVery APP are detailed in the protocol article of this studyThe main modules of the APP are:Recommendations for adherence to the Mediterranean diet. Among others, it is recommended that potential nutritional deficiencies in vitamin D, vitamin B12, complex B, folic acid, and omega-3 fatty acids be supplied.Recommendations to improve the quality of sleep and rest. The need to attain an average of 7 to 8 h of sleep each night is encouraged to ensure sufficient rest.Physical exercise recommendations with graphic representations. The contents and instructions in this section were based on guidelines for the management of this disease or other pathologies with similar symptoms.Respiratory physiotherapy exercises with video tutorial support.Cognitive stimulation exercises with different difficulty levels. Three levels of cognitive stimulation exercises are provided, which are aimed at working on cognitive skills focused on executive function, difficulty maintaining attention, decreased processing speed, verbal fluency, and short-term memory deficits.Participation in community resources. The aim is to promote participation in the local development process through different services, associations, or cultural activities, as well as groups affected by the same pathology.
