This is a weak study that is exemplary of psychology's weak experimentation culture and correlation/causation laundering, especially with regard to self-report.

The heavily hinted implication is that device use damages relationships. But look at what they actually measured. They ask adolescents to answer questions like:

"My primary caregiver ignores me when they are on a device." (DAIS, their new scale)

And then also ask them to answer questions like:

"I often worry that this person doesn't really care for me." (ECR-RS)

And then act like it's a revelation that these two self-report scales are correlated.

A much more plausible causal explanation is that a single psychological variable (e.g. a bad relationship) causes both self reports, rather than the implied pathway that device use causes A, which then causes B.

I largely agree this is a weak study, but it also feels like no matter how you run this study it's going to be flawed.

Parent-child interactions, relationships, feelings are probably the hardest thing to quantify at any scale.

In the end, it's really, "Pay more attention to your kids", which is a pretty good universal message to put across.

> A much more plausible causal explanation

Why is that much more plausible? It implies that it has always been there, and that nothing has changed since the last century, which is unlikely. Unless you want to introduce some other recent factor, but that is going to be even less likely.

And why? Because other studies have shown how addictive "phone" use is, and how it isolates people. And addicts (drugs, alcohol) are bad caretakers.

So there's really nothing that makes the explanation implausible.

You may ask yourself if it's not your own addiction speaking.

To be fair they do kinda spell this out in the discussion section:

This study does not come without limitations. First, it is important to recognize that the present findings are correlational and cross-sectional in nature and therefore do not permit conclusions regarding directionality or causality. Although caregiver device-centric behaviors and adolescent attachment insecurity were robustly associated, it remains unclear whether perceived caregiver distraction is related to attachment insecurity, whether adolescents with higher levels of attachment insecurity are more likely to perceive caregiver behavior as inattentive or disruptive (i.e., reverse causality), or whether both reflect other unmeasured contextual or relational factors. Second, several of the DAIS items assess emotional reactions, which could conceptually overlap with anxious attachment. Thus, the relationship between the DAIS and ECR may reflect a partial overlap of the constructs. Third, both the DAIS and ECR-RS are self-reported measures at a single time point, which may have shared method variance. [...]

I definitely think some people get addicted to the phones, and that addiction is negative for the relationship with the child. I also think one can be active on a phone while also being attentive and available to the child, which would be less problematic for the relationship.

I also don't think the phone is new in this regard. I've certainly heard many stories from back in the days about parents being glued to the TV or work and not being attentive to their child. It's even the point of the quite well known song Cat's in the Cradle[1].

The main difference I guess is that the phone is so prevalent in the population, and there are a lot of apps and sites that are engineered to grab your attention.

IMO this isn't necessarily bad (it's one way to get data), but the numbers are meaningless without a control. Unfortunately, I think we missed that bus by ~20 years. Had the same study been conducted every few years over the last two decades, I think it would have been valuable. Maybe it is still valuable to do this once every few years? (I think that everyone in 2026 is maximally addicted to mobile phones, but maybe I'm wrong and it can get worse).

My dude, I don’t know how to explain this to you but phones and computers are addictive for people. They get hooked on them to feed the lizard brain with digital junk food engineered for engagement.
