Brief Summary
The main objective of this study is to evaluate the effectiveness of DIAL (an innovative and user-friendly solution based on Multiplatform Voice Assistive Technologies) in reducing unwanted loneliness and increasing the mental health and the quality of life in individuals over 65 years old. Additionally, a secondary objective is to evaluate the experience of using the system, including aspects of usability and satisfaction, and to analyze whether the functionalities provided by DIAL contribute to the improvement of various dimensions in the lives of the elderly. It is hypothesized that DIAL will reduce unwanted loneliness and improve mental health in older people. In addition, we aim to obtain positive ratings in terms of usability and satisfaction with DIAL, along with the verification that most of the functionalities provided by DIAL will be useful to older people.

Outcome Measures
Primary Outcomes (5)
UCLA Loneliness Scale (UCLA; Russell et al., 1980; Vázquez & Jiménez, 1994)
The instrument measures the feeling of loneliness and consists of 20 items, 11 of which are negative (for example, I lack company) and nine positive (for example, I feel in tune with the people around me). All items are scored from 1 (never) to 4 (frequently). After reversing the score on items 1, 5, 6, 9, 10, 15, 16, 19 and 20, the scores corresponding to the 20 items are added, obtaining a total isolation score. The range of scores goes from 20 to 80, with a higher score corresponding to a greater degree of loneliness
Pre-intervention, immediately after the intervention, and follow-up (3 months)
Health-related quality of life scale (EuroQol-5D; Herdman et al., 2001).
This scale measures five dimensions of health: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each category consists of 1 item, ranging from 1 (no problems) to 3 (many problems). The second part of the EQ-5D-3L is a 20-centimeter vertical visual analog scale, ranging from 0 (worst imaginable health state) to 100 (best imaginable health state). The individual must mark the point on the scale that best reflects the assessment of their current global health status. The use of the VAS provides a complementary score to the descriptive system of self-assessment of the individual's health status
Pre-intervention, immediately after the intervention, and follow-up (3 months)
The World Health Organization Quality of Life-Old (WHOQOL-OLD Scale; Power et al., 2005; Lucas-Carrasco et al., 2011).
The WHOQOL-OLD is a 24-item self-report instrument that is divided into six facets: Facet 1- Sensory abilities (items 1, 2, 10, 20); Facet 2- Autonomy (items 3, 4, 5, 11); Facet 3- Past, present and future activities (items 12, 13, 15, 19); Facet 4- Social participation (items 14, 16, 17, 18); Facet 5- Death (items 6, 7, 8, 9); and Facet 6- Intimacy (items 21, 22, 23, 24). Responses are based on a 5-point Likert-type response scale (ranging from 1-5), with items 1, 2, 6, 7, 8, 9, and 10 reverse scored. WHOQOL-OLD total scores in each facet range from 4 to 20, with higher scores indicating better quality of life. A global score (general QOL - GQOL) is also calculated from the set of 24 items
Pre-intervention, immediately after the intervention, and follow-up (3 months)
The Generalized Anxiety Disorder Questionnaire-2 (GAD-2; Kroenke et al., 2007; García-Campayo et al., 2012)
It is a self-report measure containing 2 items assessing anxiety symptoms. The items are scored on a 4-point Likert scale, ranging from 0 (no days) to 3 (almost every day), where a high score indicates greater anxiety symptoms
Pre-intervention, immediately after the intervention, and follow-up (3 months)
The Patient Health Questionnaire-2 (PHQ-2; Kroenke et al., 2003; Rodríguez-Muñoz et al., 2017)
It is a self-report measure consisting of 2 items assessing depressive symptoms. The items are scored on a 4-point Likert scale, ranging from 0 (never) to 3 (almost every day), where a high score indicates higher levels of depressive symptoms

Study Arms (2)
Experimental group
EXPERIMENTALParticipants randomly assigned to this group will test the DIAL device for four weeks
Control group
NO INTERVENTIONParticipants randomly assigned to this group will not use the DIAL device
Interventions
Participants in the experimental group will test in their homes a device called DIAL, a voice-controlled virtual assistant designed to communicate with the elderly and help them in different contexts. They will use it for four weeks. They will receive an individual training session on how to use the device, an instruction sheet for its use and, in addition, they will receive telephone technical support throughout the study. Finally, the device will be uninstalled and all participants will be called back to answer the same survey they answered before the intervention.
Eligibility Criteria
You may qualify if:
- \) Be 65 years old or older, 2) Speak Spanish, 3) Meet at least one criterion of vulnerability to suffering unwanted loneliness (the criteria will be taken from the European report by Baarck et al. 2021. For example, being a widower, have a physical illness...), 4) Ability and willingness to participate in the study.
You may not qualify if:
- \) Present cognitive impairment, 2) Suffer from a serious mental problem (e.g. depression, schizophrenia) or 3) Suffer from a serious physical problem (e.g. blindness or deafness) that makes interaction with the device difficult.
