Smartphone addiction test: signs of overuse and cutting back

You unlock your phone just to check the time, and thirty minutes later you are still scrolling. Even while working, your eyes keep drifting to a phone with its screen off. This is not about weak willpower: phones are designed to keep you reaching for them. Here is how to see where your use stands and how to ease off a little at a time.

Does long screen time always mean smartphone addiction? #

This article uses the term smartphone overdependence, as the scale below does, rather than addiction. Some people use their phones for long hours because of work, so the focus is not time itself but finding it hard to control your use and running into problems in daily life because of it. The adult scale used in Korea’s national survey does not ask about screen time at all.

There are reasons the phone keeps calling. New notifications, feeds that never end and messages that could arrive at any moment keep up a constant sense of ‘maybe something came in’. A phone is also the easiest way to shift your mood when you are bored, anxious or tired. That is why overdependence tends to deepen during hard stretches.

What does smartphone overdependence look like? #

The Smartphone Overdependence Scale divides it into three areas. Which area stands out shapes what to try first.

• You look at your phone ‘for a minute’ before bed and keep falling asleep later.
• Faced with a task, you pick up your phone first and feel heavier afterwards.
• You feel uneasy without your phone in hand and keep waking the screen with nothing to check.
• Your phone causes arguments with the people you are spending time with.

How do I read a smartphone addiction self-check? #

The check below uses the 10 questions of the adult Smartphone Overdependence Scale from Korea’s National Information Society Agency (NIA). You answer on four levels while thinking about your recent phone use, and the total ranges from 10 to 40. The result screen shows 24–28 as increased concern and 29 or more as higher concern, along with a score for each of the three areas.

If your score is high, look at the three area scores too. A high loss-of-control score points to tools that help you cut back, high salience points to putting distance between you and your phone, and high consequences point to working on the difficulties that have already appeared. A diagnosis is made in a clinical conversation.

Does heavy phone use affect mental health? #

A systematic review of 23 studies (Elhai et al., 2017) found that problematic smartphone use was consistently related to depression (at least a medium effect) and also related to anxiety, though with a small effect. A meta-analysis of 41 studies with 41,871 children and young people (Sohn et al., 2019) reported problematic use in about one in four (median 23.3%), and it came together with depression, anxiety, stress and poorer sleep quality.

Most of these studies measured people at a single point in time, so they cannot tell whether phones lead to low mood or low mood leads people to lean on their phones. Often the two feed each other. That is why, alongside cutting back, it helps to look at the feelings your phone has been soothing.

How can I cut back on phone use? #

In an experiment that split 143 university students into two groups (Hunt et al., 2018), the group that limited social media to a short time each day for three weeks reported less loneliness and depression. Interestingly, the group that only tracked their use also reported less anxiety and less fear of missing out. Simply noticing can start the change. Try the five steps below one at a time.

1. Note the moments you pick it up — for three days, write down just five times you reached for your phone without meaning to: the time, what you were doing just before and how you felt. Patterns will show up.
2. Keep it out of reach — while working or studying, leave your phone in another room or in a bag. Distance is far easier than holding back by willpower.
3. Turn off notifications — keep only messages from people and switch the rest off. When your phone calls you less often, the checking habit eases too.
4. Take it out of bed — put the charger somewhere away from your bed. Getting back the time before sleep changes the next day. Our guide to racing thoughts at bedtime may also help.
5. Pick one replacement — decide in advance what you will do in the moments you would grab your phone. Something small works: a glass of water, looking out of the window or a short walk.

If you keep escaping into your phone when a task is waiting, the starting point may be the overwhelm you feel in front of the task rather than the phone itself. Our guide to procrastination looks at that loop.

If it is hard to sort out on your own what you were feeling each time you reached for your phone, you can start by going through it one step at a time in a conversation.
