Children’s interaction with the online world is a hot topic – recently, The Economist magazine asked whether smartphones are to blame for recent increases in the rates of suicide among girls [1]. This week, the Children’s Commissioner for England published a report evidencing the effect of pornography on harmful sexual behaviour among children and suggesting a link between exposure to pornography and children being given their own phones at younger ages [2].

I was 21 when I got my first mobile phone and over 30 when I got my first smartphone, but today’s children and young people are growing up in the digital world where the concept of a ‘brick phone’ or landline is alien, and smartphones are the norm. As technology plays an ever-increasing role in our lives, it’s not surprising to learn that children are acquiring smartphones at a younger and younger age. To illustrate, in 2018, 35% of 8–11-year-olds owned a smartphone [3] and this had risen to 60% by 2022 [4].

So how do parents make the decision to give their child a smartphone?

This question fascinated me – both as a parent with a son approaching 11 years old and as a researcher interested in young people’s wellbeing in a digital world. I could hear many of my friends and peers with children of a similar age debating what to do and I took the opportunity, whilst waiting for my PhD to officially begin, to examine this, with the support of my supervisor Prof Leslie Gutman.

Our study, published this month, on parents’ perspectives of their children’s smartphone ownership [5], involved interviewing 11 mothers and fathers of 9- to 12-year-old children and using the COM-B model to identify which elements of Capability, Opportunity and Motivation were influencing their decision making.

Our analysis identified a number of influencing factors across all three COM-B domains:

• The external environment was a key enabling factor in parents deciding to give their child a smartphone; parents see smartphones as an inevitable aspect of the modern world that can only be resisted for so long because ‘technology is everywhere’.
• Added to this, the pressure of peers being given a smart phones – the social opportunity – creates a ‘domino effect’ which then affects parents’ motivation, making them want to prevent their children being left out and help them build their social relationships.
• They also see advantages in being able to track their child’s movements and ensure they are contactable once they start travelling independently to and from school. ‘When they… go to school by themselves, then obviously I need to give the smartphone’. Hence the transition from primary school is a key time for many children being given a smartphone.
• However, parents are conflicted. They also have worries about their children entering the world of smartphones and the unfettered access to the internet that this can bring. ‘Having his phone in his room at night is a big worry for me’.
• They worry about the impact of social media, about bullying, about overuse and addiction but are sometimes unsure of what the real benefits and risks are. ‘I think there are certain risks and I think there are certain benefits but it’s all kind of in my own head’.

This uncertainty is understandable. Evidence is mixed on the impact of smartphones on younger children, with many recognising that smartphones can support learning and increase digital skills which are important for life in a technological world. At the same time, whilst causal linkages are hard to demonstrate, correlations are apparent between smartphones and sleep disturbance, anxiety and academic performance. It seems clear that young people are also particularly prone to Problematic Smartphone Usage (where usage interferes with daily life and activities).

So where to go from here?

The parents we spoke to were grappling with their decision-making. They felt that there was a lack of guidance and support for them in planning how and when to give their child a smartphone. This challenge is heightened because their own digital technology skills and knowledge are often inferior to their child’s, meaning that their efforts to control usage and access can be undermined by a tech-savvy child. Our paper discussed potential intervention strategies (using the Behaviour Change Technique Taxonomy (v1) [6] including:

• Restrictions such as having a recommended minimum age for smartphone ownership
• Guidance and support for parents preparing and planning to give a child their first smartphone
• Education from credible sources on the benefits and risks of smartphones for children
• Training in setting up appropriate controls on a child’s smartphone

Whether there is a role for regulation and restriction (such as age limits) of smartphones is a debate that rages. In either case, it seems clear that expecting parents to navigate this significant decision on their own is too much. Given the potentially lasting impacts of owning a smartphone for children, better guidance and support from authoritative, trusted sources are required.

This blog article is dedicated to a panel discussion from the CBC Conference Enabling Behaviour Change to Build Back Better for health & sustainability: 1 – 3 Nov 2021. An interdisciplinary panel of experts took us on a journey from how we define and measure engagement to how we learn from big data and produce a generalisable science of factors that promote engagement.

We kicked off the engagement panel with Dr Kevin Doherty from Technical University Denmark, who began his quest to conceptualise engagement from a review of the computer science literature. Kevin was struck by the wide range of perspectives and conceptualisations of engagement from ‘a quality of user experiences with technology’ (O’Brien and Toms, 2008) to ‘..the phenomena of being captivated and motivated’ (James et al. 2011). To help understand where these different perspectives were coming from, Kevin and his team turned to the original theories, revealing a huge range from most cited Flow Theory (50 mentions) to least cited Richness Theory (2 mentions). Still struggling to pin down what exactly was meant by engagement, Kevin and his team looked next at measurement for further insights. They uncovered a long list of measures such as questionnaires, behaviour logging, facial analysis, and gesture tracking. Next, they looked at the design strategies used to design for engagement and reported a variety of strategies including recommendations such as ‘usability’, ‘immersing users’ and ‘inspiring fun’. As these strategies were employed across a range of contexts and technologies, they were still no closer to pinning down exactly what was meant by ‘engagement’. A combination of Kevin’s applied work and academic review led to thinking about engagement not only in terms of what it is, but how we might design for engagement as a process and how users engage with technology as a process in itself. Kevin ended his talk around remaining challenges, one being how we build interdisciplinary teams and the necessary knowledge to facilitate this kind of approach to engagement.

Our next panellist was Professor Rik Crutzen from Maastricht University brought us on to the topic of measuring engagement. Rik stated as with any psychological construct, it’s important to ‘disentangle’ this conceptualisation from how it is measured. These are not two separate entities but related to one another. As with measuring psychological constructs, we use a plethora of methods to measure engagement such as surveys and reaction times. Interestingly and in contrary to some of the audience’s views, Rik argued against a standardised way of measuring engagement. Instead we ought to keep a ‘decentralised’ meaning, as ultimately it will depend on the context and how we are conceptualising engagement in the first place. Rik’s second point related to the distinction between measuring intended and actual use of an intervention and methods employed to understand usage behaviours. For example, ‘Think aloud’ procedures can help to uncover if certain user groups go to different places on a website and whether any content is misinterpreted, allowing an organisation to continually refine their intervention. Rik’s final point addressed the novel ways to reduce participant burden and increase engagement. For example, avatars can be used as a proxy for psychological constructs and skip logic in questionnaires can help to reduce participant burden via shorter questionnaires. Indeed, reducing participant burden is key to sustaining users’ engagement with an intervention and must be prioritised.

Next on the stage was the panel’s industry expert: Charlotte Summers COO and Director of Research at DDM Health. Charlotte Introduced GRO – a digital platform providing disease-specific education, behaviour change support and feedback to optimize health and wellbeing. Gro has been developed with leading clinicians to address all modifiable risks. Charlotte shared encouraging research findings from peer-reviewed published health outcomes including: Type 2 diabetes remission, weight loss, reduce medication, reduced anxiety, depression and perceived stress. So, what’s in this successful platform? Charlotte described the following features: personalised resources; one-to-one behaviour change coaching; goal setting; community support and integrated tracking. It also uses AI software to optimise engagement and health outcomes. This platform is a patient-healthcare platform to allow real-time health monitoring and engagement information. Charlotte demonstrated through a case study how ‘big data’ can be used to provide answers on intended vs actual use. They noticed that it was actually the younger family members using the app on behalf of their older relatives that did not speak the language or were not digitally literate. These insights allowed them to further refine the app and offer even more personalisation, with a recognition that is important to engage not just the individual, but the family as a whole in helping to manage type 2 diabetes.

The final panellist was Dr Olga Perski from UCL who took us through a stimulating presentation on whether current approaches are getting us closer to identifying ‘timeless’ design elements. Olga drew our attention to the current state-of-the-art around identifying design elements that reliably influence engagement. This of course is important for designing websites/apps that people want to use and saves money through reduced testing of design iterations. Olga’s talk highlighted the importance of an interdisciplinary team with expertise in how we use a combination of user-centred design (e.g., co-design workshops) and experimental methods (e.g., factorial trials) to better understand design elements that influence engagement with health and wellbeing websites/apps. Findings from these kind of research methods have provided important insights on broader design elements such as ‘ease of use’, ‘personalisation’, and ‘interactivity’ which are important drivers of engagement. However, the challenge exists in the myriad of ways these design elements can be operationalised. One could argue, this is also where the creativity and innovation comes into play and again the importance of testing design features with the relevant target audience. In addition, Olga points out that design preferences will change over time and across contexts, which is in part due to the changing social and cultural norms/expectations. Research shows that users tend to rely heavily on “social proof” to help navigate which technologies to adopt. With deeply contextual and ever changing social, cultural norms and expectations, it’s looking increasingly challenging to identify “timeless” design elements…For example, although chatbots were seen as moderately acceptable by internet users in 2019, they will likely be more commonplace and widely acceptable in 2030. So, what’s the solution? Olga left us with the idea of embracing complexity. In line with the common theme running throughout this discussion panel, design principles, as with the conceptualisation and measurement of engagement, will largely depend upon context.

Becoming a parent is undoubtedly one of the biggest challenges a person can face. From one day to the next, a new mum is managing the steepest of learning curves, the new burden of responsibility, physical discomfort and sleep deprivation. No matter how many antenatal classes you attend, books you read and ‘poonami’ horror stories you hear, nothing can quite prepare you for the reality of life with a newborn. (more…)

Doris vacantly stared at the Sudoku puzzle on her iPad. She used to love doing these puzzles; her daughter said they would help keep her mind active. It had worked for a while, but now the time it took her to complete them was getting longer. The system calculated a score based on the time taken to complete the puzzles and then told her every week how agile her mind was. At first, she was excited by her progress. But for the past few months, when she looked at the chart of her progress, all she saw was a steady decline. It was a visible reminder that she was getting old. She wondered if it was the onset of dementia. (more…)

In a blog post aptly named “Digital Health or Digital Hell’’ on the 10^th of January this year, Dr Julia Bailey expressed concerns over the enormous number of digital aids available to assist with adopting various health behaviours. A sizeable chunk of those technologies aim (and claim) to help with weight management, be it dietary regulation or broader self-regulatory behaviours related to weight control.  As a rule, (but not always), weight management apps tend to be eye-pleasing and well thought out in terms of presentation, colours and functionality.  But research suggests that their content is very rarely evidence and theory-based and sometimes may even provide outright fake information (e.g. placing your phone on your stomach to break up fat cells through the vibrate function).  In my field of research- yoyo dieting – you are most likely to encounter savvy, experienced dieters, who have become experts in their own weight loss. While they are unlikely to buy into such dubious solutions, dieters are likely to try apps that appear to present legitimate advice.
