User-centered development of an internet-based CBT intervention for the treatment of loneliness in older individuals.

Background: Loneliness is a widespread phenomenon associated with a number of negative health outcomes. Older individuals may constitute one important target group with a need for effective interventions. However, despite evidence showing that addressing maladaptive social cognition (e.g., via cognitive behavioral therapy [CBT]) is the most effective intervention strategy for reducing loneliness, most existing programs aimed at older individuals do not use that method. Further, in terms of mental health service use, older individuals have been found to be an extremely undertreated population. When developing interventions, active involvement of end users in the development process is essential to increase later uptake. Objective: The aim of the present study was to develop an internet-based CBT intervention for loneliness in older individuals (i.e., aged ≥65 years) applying a user-centered design. The present report provides an in-depth description of the development process. Methods: Two phases of qualitative data collection were conducted in parallel with intervention development using a sample of N = 12 participants including both potential end users (i.e., older adults) as well as experts (i.e., psychotherapists). Measures included semi-structured interviews and usability testing. Results: In Phase 1 interviews, participants indicated that they were predominantly positive about the idea of an internet-based program for loneliness targeting older individuals. Individualization and interactivity were named as crucial features. In Phase 2, usability testing of a prototype program provided important insights into technical barriers to intervention use. Further, participants reported that they were missing content on philosophy/theology and the role of descendants/relatives. Valuable insights from Phase 1 and Phase 2 were incorporated into the intervention program resulting in a 7-module internet-based self-help CBT intervention. Discussion: Findings of this study highlight the significance of including relevant stakeholders in the development process of an intervention. Additionally, results emphasize the high acceptance of internet-based interventions in this population, but also underline the need for considering age-specific aspects when developing treatments.

User-Centered Development of STOP (Successful Treatment for Paranoia): Material Development and Usability Testing for a Digital Therapeutic for Paranoia.

BACKGROUND: Paranoia is a highly debilitating mental health condition. One novel intervention for paranoia is cognitive bias modification for paranoia (CBM-pa). CBM-pa comes from a class of interventions that focus on manipulating interpretation bias. Here, we aimed to develop and evaluate new therapy content for CBM-pa for later use in a self-administered digital therapeutic for paranoia called STOP ("Successful Treatment of Paranoia"). OBJECTIVE: This study aimed to (1) take a user-centered approach with input from living experts, clinicians, and academics to create and evaluate paranoia-relevant item content to be used in STOP and (2) engage with living experts and the design team from a digital health care solutions company to cocreate and pilot-test the STOP mobile app prototype. METHODS: We invited 18 people with living or lived experiences of paranoia to create text exemplars of personal, everyday emotionally ambiguous scenarios that could provoke paranoid thoughts. Researchers then adapted 240 suitable exemplars into corresponding intervention items in the format commonly used for CBM training and created 240 control items for the purpose of testing STOP. Each item included newly developed, visually enriching graphics content to increase the engagement and realism of the basic text scenarios. All items were then evaluated for their paranoia severity and readability by living experts (n=8) and clinicians (n=7) and for their item length by the research team. Items were evenly distributed into six 40-item sessions based on these evaluations. Finalized items were presented in the STOP mobile app, which was co-designed with a digital health care solutions company, living or lived experts, and the academic team; user acceptance was evaluated across 2 pilot tests involving living or lived experts. RESULTS: All materials reached predefined acceptable thresholds on all rating criteria: paranoia severity (intervention items: ≥1; control items: ≤1, readability: ≥3, and length of the scenarios), and there was no systematic difference between the intervention and control group materials overall or between individual sessions within each group. For item graphics, we also found no systematic differences in users' ratings of complexity (P=.68), attractiveness (P=.15), and interest (P=.14) between intervention and control group materials. User acceptance testing of the mobile app found that it is easy to use and navigate, interactive, and helpful. CONCLUSIONS: Material development for any new digital therapeutic requires an iterative and rigorous process of testing involving multiple contributing groups. Appropriate user-centered development can create user-friendly mobile health apps, which may improve face validity and have a greater chance of being engaging and acceptable to the target end users.

Proposal for the User-Centered Design Approach for Health Apps Based on Successful Experiences: Integrative Review.

BACKGROUND: Different strategies encompassed within mHealth have shown themselves to be effective for maintaining good health or controlling certain diseases. However, there is usually a very high rate of abandonment of health apps. Therefore, it would seem obvious that there is a need for involving the end users (whether they are health professionals, patients, or both) in the design process from the early stages in order to enable their needs and characteristics to be identified. In this sense, it is common knowledge that focusing on the user permits the consideration of valuable details aimed at making the correct adjustment between the patient, the technology, and the organization of attention. OBJECTIVE: The goal of the research was to propose a methodology based on the review of previous successful user experiences in setting up health apps by using qualitative techniques (focus groups and discussion groups) that includes the participation of information technology and health professionals and the patients themselves. METHODS: An integrative review was made of studies in which a qualitative methodology was employed mainly through focus and/or discussion groups for the design and development of health apps, consulting diverse databases (PubMed, Scopus, and Proquest) with the following search strategy: "mHealth AND apps AND focus group OR discussion group." A total of 69 papers were included in the review. RESULTS: A proposal structured in 4 sessions of variable duration was made in which information technology and health professionals and patients take part: composing, preparing, and organizing contents (session 1); testing structure and usability (session 2); does the app fit the needs of end users? (session 3); and last testing-keep on improving (session 4). Throughout the sessions, we propose studying aspects like previous user experiences in mHealth, barriers to the adoption of mHealth, interface contents, management and browsability, usability, perceived quality, security and privacy, capacity to self-manage disease with the app, ergonomics, and glanceability, etc. Specific tools that have proved useful in previous research for measuring these aspects are presented. CONCLUSIONS: These work sessions would be based on predominantly qualitative methodologies although, as they evolve, validated questionnaires permitting the assessment of the objectivity of certain technical aspects could be incorporated. With this proposal, a project centered on end users could be effected, responding to their needs. However, this requires validation that will be made via implementation in the development of health apps, with the subsequent measurement of results in terms of adherence and improvement in the clinical variables of the end users.
