Can social robots improve children’s mental health? What we know and what we still need to learn

This blog post discusses some of the key findings from the article “Socially Assistive Robots as Mental Health Interventions for Children: A Scoping Review” published in the International Journal of Social Robotics (2020, paper here).


What is a social robot?

Social robots are small robotic devices that are capable of social interactions, such as cooperation, instruction and play. The robots can be shaped like animals (e.g., Aibo – the robotic dog (Fig. 1(a)) or characters (e.g. humanoid robot Nao (Fig. 1(b)). Among other functions, social robots can play a therapeutic role (1), serve as companions (2) and aid in education (3,4). One of the application areas of social robotics is therapy for children with autism spectrum disorder. In this domain, robotic companions have the potential to improve a variety of behavioural outcomes, including social and language skills (5). Social robots are also used with older populations. For example, robots like Paro (Fig. 1(c)) are being used in elder care settings. This baby harp seal lookalike helps reduce loneliness and agitation among residents (6).

A new mental health intervention for children

Since social robots seem to have a positive impact on mental health in different populations, there is a growing interest in using them as a tool to promote and improve mental health among children. As a result, a number of studies are being conducted to test social robots in this relatively new domain. In the Neuroscience Engagement and Smart Tech (NEST) Lab, we collected and analyzed the existing research studies which investigate the use of social robots to improve children’s mental health (10), to get a fuller view on what interventions are being tested and how.  

What we know: Feasibility and short-term effects

Using social robots to benefit children’s mental health is a new and rapidly developing field. Hence, the majority of currently available studies are intended as means of exploring what is possible and what could be effective in the future. The studies usually include a single session with the robot, which shows only short-term outcomes of the interaction. While the evidence does not allow for drawing strong and long-term conclusions, the studies in our sample demonstrate that various robotic interventions are feasible. We know that social robots can be introduced and deployed in therapy, clinical and other settings. But perhaps the most crucial aspect of determining whether robotic companions could be successful, is the fact that children participating in the studies usually showed a positive response to the robots and were engaged in the interaction, e.g., distraction during vaccination (11). This positive reception makes the developments in the use of social robots promising.

What we still need to learn: Effectiveness and social impact

To be able to draw conclusions about the effectiveness of robotic interventions we need more evidence. Future research in this field needs to systematically address well-focused questions around specific outcomes (e.g., stress reduction). Additionally, potential social impacts of the robots should be more carefully considered. Robots are intended to be introduced into different environments as social entities. For example, a robot present at a hospital to distract children during medical procedures will likely affect others around the child such as parents and nurses. Moving forward, we need to learn more not only about specific social robot interventions that can be helpful, but also about how introducing social robots into new environments will affect social dynamics.

What about ethics?

Conducting child-robot interaction research comes with unique ethical concerns. In our scoping review of the literature, we found that the majority of studies in the sample provide only generalized statements about the assent process used (10). Transparency about how the robot is introduced and described  to young participants is crucial, as children of different ages may have different beliefs about the animacy of robots. Other notable ethical considerations include attachment and deception. For example, children could experience distress when the robot is taken away or mistreated (12). The key to proactively addressing these ethical issues could be using participatory approaches throughout the research process. Working together with children and parents will help minimize the risk and maximize the benefit of future social robot mental health interventions.
