Abstract

It has been more than a decade since a concern about the addictive use of the Internet and mobile phones was first expressed, and its possible inclusion into the lists of mental disorders has recently become a popular topic of scientific discussion. Thus, it seems to be a fitting moment to investigate the prevalence of this issue over time. The aim of the present study was to analyze the prevalence of the perception of problematic Internet and smartphone use in young people over the period 2006–2017. To this end, a questionnaire on Internet use habits and two questionnaires on the negative consequences of Internet and smartphone use were administered to a sample of 792 university students. The scores were then compared with the results of former studies that had used these questionnaires. The perception of problematic Internet and mobile phone use has increased over the last decade, social networks are considered responsible for this increase, and females are perceived to be more affected than males. The current study shows how strong smartphone and Internet addiction and social media overlap. Participants from 2017 report higher negative consequences of both Internet and mobile phone use than those from 2006, but long-term observations show a decrease in problematic use after a sharp increase in 2013. We conclude that the diagnosis of technological addictions is influenced by both time and social and culture changes.

TL;DR

This study compared 2017 survey data from 792 Spanish university students with earlier cohorts from 2006–2017 using the CERI and CERM to track perceived problematic Internet and smartphone use. Perceived negative consequences rose from 2006 to 2013, then declined by 2017, with social network use and female gender linked to higher perceived smartphone-related problems.

Key findings

  • In the 2017 cohort, the mean CERI score was 18.04 (SD = 4.50) and the mean CERM score was 15.77 (SD = 3.50); the correlation between CERI and CERM was high (r = 0.76, p = 0.000).
  • Problematic Internet use rose from 1.5% in 2005 to 6.4% in 2017, and problematic mobile phone use rose from 0.6% to 3.0%.
  • 375 students (47.4%) agreed or strongly agreed with “I am addicted to the Internet,” and 73.2% answered that girls are more Internet-addicted than boys; those who strongly agreed scored significantly higher on both CERI and CERM (correlations 0.38 and 0.34, p < 0.001).
  • Scores increased from 2006 to 2013, showed no significant 2013–2015 difference, then decreased from 2015 to 2017 (p < 0.001 for CERM; CERI decreased from 2013 to 2015 and 2015 to 2017, p < 0.001). Women had higher CERM scores but not CERI scores.

Methods

  • Cross-sectional survey conducted in May 2017 with 792 Universitat Ramon Llull students (mean age 21.6 years, SD = 3.3; 76.5% women), compared with five prior cohorts from 2005–2016 in Spain, the United States, and Colombia.
  • Instruments included an ad hoc sociodemographic and Internet-use habits questionnaire, the 10-item CERI, and the 10-item CERM, both using 4-point Likert scales and summed to a maximum of 40 points; Cronbach’s alpha was 0.76 for CERI and 0.73 for CERM in the present study.
  • Analyses included Student’s t-tests, correlations, and a multiple analysis of variance for gender and year of questionnaire administration on CERI and CERM scores, with post-hoc Bonferroni pairwise comparisons.

Limitations

  • Stated by the paper: university students are not representative of other young people; problematic use does not correspond to a diagnostic entity; CERI and CERM are self-report measures created before smartphones and should be updated; cultural differences between samples may influence differences more than time.
  • Evident from the text: the design compares separate cohorts rather than following the same individuals longitudinally, and the samples differ by country, university, and year; the measures capture perceived problems, not clinical diagnoses.

    The CERI and CERM scores are comparable across the different cohorts and years of assessment.

    “The data on problematic Internet and mobile phone use obtained in the present study (called Cohort 6 hereinafter) was compared with data obtained from other cohorts of university students who answered the CERI and CERM questionnaires in studies conducted by our team between 2006 and 2017”

    The compared cohorts differ primarily in year of assessment and not in other characteristics (e.g., country, university, degree composition) that could affect CERI/CERM scores.

    Self-reported perception of problematic Internet and smartphone use is a valid indicator of actual problematic use.

  • Conflicting claims about gender differences in problematic use

    Major

    The discussion says women's problematic use is greater, but later says there were no gender differences in problematic mobile phone or Internet use. The text does not specify a different cohort or analysis to reconcile these claims.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
