Phone Addiction Test: Are You Actually Addicted?

A phone addiction test can tell you whether your smartphone use is normal, borderline, or clinically problematic. The most widely used test in research is the SAS-SV (Smartphone Addiction Scale - Short Version), a 10-question assessment published in PLOS ONE with a reliability score of 0.911. Below, you can score yourself on the same scale researchers use in clinical studies.

If you're reading this, you probably already suspect the answer. Maybe you've caught yourself scrolling without purpose for the third time today. Maybe you felt a jolt of panic when your battery hit 5%. Or maybe someone in your life has started giving you that look when you reach for your phone mid-conversation.

Suspicion is fine. But a number is better. Let's find yours.

The SAS-SV Phone Addiction Test

The Smartphone Addiction Scale - Short Version was developed by Kwon et al. in 2013 and has been used in hundreds of peer-reviewed studies since. It measures 10 specific behaviors. For each statement, rate yourself from 1 (strongly disagree) to 6 (strongly agree). Be honest. Nobody's watching.

What Your Phone Addiction Test Score Means

Add up your scores across all 10 questions. Your total will fall between 10 and 60.

The clinical cutoffs established by Kwon et al. are 31 for men and 33 for women. If you scored above those numbers, you're in the range that researchers classify as problematic smartphone use. That doesn't mean you have a clinical disorder. It means your phone habits have crossed the line from convenient to compulsive.

If you scored in the 23-30 range, you're not in the red zone yet, but you're closer than you think. Most people in this range report that phone use is already affecting their sleep or focus in ways they notice but haven't addressed.

A Second Test: The Greenfield Smartphone Compulsion Test

Want a second opinion? Dr. David Greenfield, founder of the Center for Internet and Technology Addiction at the University of Connecticut School of Medicine, developed a 15-question yes/no test. It's less granular than the SAS-SV but faster to take.

The Greenfield test asks questions like "Do you find yourself spending more time on your smartphone than you realize?" and "Do you feel reluctant to be without your smartphone, even for a short time?" If those hit close to home, you already know where this is going.

Both tests are screening tools, not clinical diagnoses. But when two validated instruments point in the same direction, the signal is worth paying attention to.

What Phone Addiction Does to Your Brain

A phone addiction test measures behavior. Brain imaging shows what's happening underneath.

In 2017, Dr. Hyung Suk Seo and colleagues at Korea University used MRS (magnetic resonance spectroscopy) brain scans on smartphone-addicted young people. They presented their findings at the Radiological Society of North America annual meeting. The result: addicted users had significantly elevated ratios of GABA to glutamate in the anterior cingulate cortex.

That matters because the anterior cingulate cortex handles impulse control. GABA is an inhibitory neurotransmitter that slows brain activity. When the ratio is off, your brain's braking system isn't working properly. You want to put the phone down, but the signal to stop is weaker than the signal to keep scrolling.

That's the important part. The brain changes are real, but they're not permanent. The same study found that after CBT, the neurochemical ratios returned to normal. Your brain adapted to the phone. It can adapt back.

Why Most People Score Higher Than They Expect

Here's the uncomfortable truth about phone addiction tests: almost nobody thinks they'll score high, and almost everybody does. A 2025 Reviews.org survey found that 57% of Americans consider themselves addicted to their phones. But when people actually take the SAS-SV, the average score tends to land squarely in the "mild overuse" range.

The disconnect makes sense. We're terrible judges of our own habits. You probably know how many cups of coffee you drink. You probably have no idea how many times you check your phone. (It's around 186 times a day, if you're curious.)

A 2020 systematic review in the Journal of Behavioral Addictions by Harris et al. found that while most phone addiction scales show strong internal consistency, they tend to underperform on test-retest reliability. Translation: your score will shift depending on your mood, your recent phone use, and how honest you're feeling. The test captures a snapshot, not a photograph.

Take it again in a week. If the number stays high, trust it.

What to Do If You Scored High

A high score is not a verdict. It's information. And information is only useful if you do something with it.

When to Talk to a Professional

If your SAS-SV score is above 40, or if your phone use is seriously affecting your job, relationships, or mental health, a screening tool isn't enough. Talk to a therapist who specializes in behavioral addiction. The same CBT techniques that normalized brain chemistry in Seo's study are available through licensed clinicians.

This isn't about weakness. Smartphone addiction activates the same reward pathways as gambling. The psychological effects are well documented. Asking for help is the rational response to a 38+ score, not a sign of failure.
