The goal of this clinical trial is to test the effectiveness of the use of mobile application ("OcupApp") to generate a personal self-analysis about meaningful activities in which adults between the ages of 50 and 70 with anxiety and subclinical depression participant.

A randomized study will be carried out comparing the effects of the use of the application "OcupApp" with a control intervention on the quality of life related to health, mental health, frequency of participation on meaningful activities, and perceived occupational balance.

OcupApp is a mobile application developed within the research team, which aims to promote occupational self-analysis in adults with depression and/or anxiety. The mobile application allows to offer feedback to participants about the meaning of the activities they carry out daily and their perception of occupational balance, which generates a subjective self-reflection that can lead to the implementation of some personal changes in their weekly routine. For this, the person must register the activities they carry out throughout a week and mark each one of them with a punctuation related to the meaning of the following dimensions: identity, pleasure, competence, importance and value of the activity by other people. The punctuation give will be on a Likert-type scale from 1 to 5. The application also allows to collect other information such as where the activity takes place, its duration, and the people with whom it is carried out. Also, at the end of the week, the application will ask users about their perceived occupational balance. All the information registered in the mobile application will be returned to the person in a dynamic and understandable way. Based on this, the person can establish two goals to accomplish. In this sense, OcupApp will offer personalized recommendations based on the objectives to be achieved related to the dimensions of meaning.
