How parents’ smartphones affect teenagers’ attachment, according to Frontiers in Psychology

What if the biggest screen issue at home was not the children’s? A new scientific study shows how parents’ digital distraction can weaken teenagers’ emotional bonds, challenging some of our assumptions about family life.

Teenagers are regularly criticised for living with their eyes glued to their smartphones. Yet a scientific paper published on 18 June in the specialist journal Frontiers in Psychology turns the spotlight the other way: parents’ screens can be a problem too.

Why parents’ smartphone use is under scrutiny

Led by US researchers, including psychologist Don Grant, the work began with a simple question a young girl asked her mother: “Mum, do you love your phone more than me?”. That clinical example prompted the team to examine parental “technoference” and “phubbing” - in other words, ignoring your child because notifications and devices take priority.

How the Device Attachment Interference Scale (DAIS) was used

To quantify the phenomenon, the scientists recruited a representative sample of 600 American teenagers aged 12 to 17. They then created a tool called the Device Attachment Interference Scale (DAIS), designed to measure how young people perceive their parents’ availability.

Participants were asked to respond to statements such as: “My parent ignores me when they are on their device” or “I feel invisible when I want their attention and they won’t put their screen down”.

The aim was to compare these answers with standard psychological assessments based on attachment theory. In practical terms, the researchers wanted to know whether smartphones trigger two defensive responses in teenagers: anxiety - an unhealthy need for reassurance driven by fear of rejection - or avoidance, meaning emotional withdrawal and distance as a form of self-protection.

A real risk of emotional insecurity linked to parental screens

The findings are unequivocal: digital distraction leaves a mark. The experts identified a very clear and hard-to-dispute statistical correlation between adults’ dependence on screens and their children’s distress. The more teenagers believe their parents are hooked on their smartphone, the higher they score on “insecure attachment”.

In other words, feeling sidelined by a screen appears to activate both defence mechanisms examined by the psychologists. Affected teenagers tend to develop both an “anxious” profile and an “avoidant” profile. On one side, they live with a persistent fear of rejection and seek attention in a disproportionate way; on the other, they gradually put up an emotional barrier and isolate themselves so they are not hurt again by that perceived unavailability.

The study also shows that the negative effect is exactly the same whether the distraction comes from the father or the mother. Even so, the authors caution against automatic, blanket blame and underline a crucial nuance: the research demonstrates a correlation, not a direct causal link.

While it is plausible that a smartphone creates distance on the parent’s side, the reverse is also possible: a teenager who is naturally more anxious, or going through an identity crisis, may be far more exacting, sensitive and irritated by even minor lapses in their parents’ attention.
