Good morning,
This test looks at the place the phone has taken in your teen's life, starting from what you, the parent, observe: the room the device takes from sleep, meals, homework, sport; what happens at night; the reaction when it is out of reach; and whether online exchanges are gradually replacing face-to-face ones. Set side by side in the report, these elements show where the use really spills over.
What you receive — a report written from your answers: what stands out, what sustains it, and where to start. This week, this month, later on.
How it is built — each axis is analyzed on its own, then cross-read with the others, through clinical reading frameworks. Your detailed answers are attached as an appendix. See an example report
The test runs over 63 questions and takes about 10 min, for a price of $3.60.
We'd also suggest reading the book Adolescence in Crisis, to take this reflection further. It's included in the price and downloadable.
If you have a question about your report, write to us at contact@psychologieetserenite.com: a psychotherapist will reply within 48 hours.

QUICK ANSWER
Is My Teen Addicted to Their Phone? — Parent Test — a 63-question self-assessment, about 10 min. This test looks at the place the phone has taken in your teen's life, from what you, the parent, observe: sleep, meals, homework, nights, reactions. Once finished, you receive a detailed PDF report ($3.60): an interpretation of its 5 dimensions, a radar chart, up to 17 clinical reading frameworks and a personalized action plan. It is designed to help you know yourself better.
This interactive test covers screens, urges, attention, sleep, tiredness, rules, commitments, lying, anger, tension, withdrawal, isolation, physical activity and readiness to change. What the test asks, for example Screens Whether your teenager spends most of a day off with their phone in hand. Whether, from one week to the next, the time your teenager spends on their phone goes down. Urges Whether your teenager turns their phone screen back on by reflex, again and again, within a short time. Whether, when you suggest an outing or a board game, your teenager chooses that over their phone. Attention Whether your teenager stops in the middle of homework or a game to look at their phone. Whether, with the phone confiscated, your teenager settles down and finishes their homework in one go. Sleep Whether, after bedtime, the light from their screen still shows under the bedroom door. Whether your teenager sleeps from bedtime to morning without you hearing their phone light up in the night. Tiredness Whether, the morning after a long evening on the phone, your teenager lingers in bed and yawns until it is time to leave for school. Whether, in the morning, your teenager gets up, gets dressed and has breakfast before touching their phone. Rules Whether your teenager keeps their phone in hand during homework and during dinner. Whether, throughout the whole meal, their phone stays put away from the table. Commitments Whether your teenager promises to stop in a moment, then is still on it much later. Whether, in the evening, your teenager puts their phone down at the planned time on their own initiative, without you having to remind them. Lying Whether your teenager tells you they are studying on their phone and you find something else entirely on the screen. Whether, when you raise the question of time spent on their phone, your teenager shows you their screen-time display. Anger Whether, when you ask them to put their phone down, your teenager raises their voice or slams their bedroom door. Whether, when you take back their phone, your teenager hands it over and moves on to something else. Tension Whether, without their phone, your teenager wanders around the house, opens and shuts the fridge, changes rooms. Whether your teenager starts an activity they enjoy on their own — sport, drawing, music — with the phone left aside. Withdrawal Whether your teenager spends the time without access to the phone in their room, door closed, answering in monosyllables. Whether, during the meal, your teenager follows the conversation, answers and keeps it going. Isolation Whether, on group outings without phones, your teenager hangs back and waits for it to end. Whether, when you suggest an outing, your teenager says yes and leaves their phone at home. Physical activity Whether, since the phone started taking up more of their time, your teenager skips training sessions or music lessons. Whether your teenager goes to their sport and activities, no matter how much time they spend on their phone. Readiness to change Whether what you've just described weighs on your life as a parent. Whether you want to take action to better support your teenager in this area.
Phone addiction is not yet a recognized diagnosis in DSM-5 or ICD-11. This questionnaire draws on research frameworks without claiming clinical screening.
This test looks at the place the phone has taken in your teen's life, starting from what you, the parent, observe: the room the device takes from sleep, meals, homework, sport; what happens at night; the reaction when it is out of reach; and whether online exchanges are gradually replacing face-to-face ones. Set side by side in the report, these elements show where the use really spills over.
The questionnaire explores 5 areas: Your reading of the place the phone has taken in your teenager's life, Intensity and priority given to the phone, Impact on sleep and the body, Withdrawal and irritability, Social withdrawal and avoidance. Your answers support reflection, not a diagnosis. A separate module explores readiness to change; it is not another trait of the model presented.
These are the aspects explored by this questionnaire. Your answers help put them into perspective.
The way you explain the place the phone has taken in your teenager's life, before the test tells you anything. This section does not measure any difficulty and does not produce a level: it collects a starting reading.
How much of your teenager's time and attention is taken up by their phone.
The effects of phone use on your teenager's sleep, fatigue and physical wellbeing.
Your teenager's emotional and behavioral reactions when separated from their phone.
Your teenager's preference for digital interactions over real-life relationships.
Your openness to exploring your teenager's phone use with them.
Answer the 63 questions honestly. There are no right or wrong answers — just choose the option that best describes you. The test takes about 10 min.

This questionnaire draws on 5 dimensions from recognized psychological frameworks (Your reading of the place the phone has taken in your teenager's life, Intensity and priority given to the phone, Impact on sleep and the body…). It's a self-assessment tool for reflection, not a clinical diagnostic instrument: it has not undergone formal psychometric validation (sample, reliability coefficient) and does not replace a professional assessment.
Your report includes an analysis by dimension, explanations and personalised points for reflection and a separate readiness-to-change module. Scores are interpreted according to the purpose and limitations of this questionnaire.
No account creation, no email required — no sign-up needed at all. Your answers are sent to our servers while you take the test. All data is automatically deleted after 30 days — see our Privacy page for full detail.
Check the introduction for who should answer: an adult, child or teenager. Do not answer on someone else’s behalf if the questionnaire asks for their own perspective.
Yes, you can retake this test as many times as you wish. Some people take it again after several months to observe how their profile evolves. Each new attempt generates its own report — previous answers are not reused.
The report organises your answers and offers points for reflection. You can discuss it with a professional; it does not replace their assessment or prescribe treatment.
Yes. Each person gets their own anonymous, unique report, based on THEIR answers. Comparing profiles within a family or couple can be useful — provided each person takes the test honestly and on their own, without influencing one another during the answers.
