Loneliness and problematic mobile phone use among adolescents during the COVID-19 pandemic: The roles of escape motivation and self-control
Open accessAbstract
In this cross-sectional study, we explored the relationship between loneliness and problematic mobile phone use among Chinese adolescents during the COVID-19 pandemic, considering the effects of escape motivation and self-control. We recruited 1034 adolescents (mean age 15.76 ± 1.20 years) from China. The results showed that loneliness was positively associated with escape motivation and adolescent problematic mobile phone use. Furthermore, when controlling for gender, escape motivation mediated the relationship between loneliness and problematic mobile phone use, and self-control moderated the relationship between escape motivation and problematic mobile phone use. Specifically, as self-control increased, escape motivation was less likely to induce problematic mobile phone use. Thus, loneliness and escape motivation may be factors that increase the risk of problematic mobile phone use, and self-control should be considered in prevention and intervention strategies aimed at attenuating adolescent problematic mobile phone use.

“Second, response bias may exist in self-reporting, although we took measures to reduce adolescents’ worries about participating, such as giving them clear instructions, telling them there were no right or wrong answers to the questions, and emphasizing the confidentiality of the results.”

Loneliness precedes escape motivation and problematic mobile phone use in time, as required for the mediation model.
“we used the PROCESS macro for SPSS (model 4) to examine the mediating effects of escape motivation in the relationship between loneliness and PMPU.”

There are no unmeasured confounders of the relationships among loneliness, escape motivation, and problematic mobile phone use beyond gender.

The sample of adolescents from three high schools in Sichuan and Chongqing is representative of Chinese adolescents during the COVID-19 pandemic.
“We recruited 1034 adolescents (mean age 15.76 ± 1.20 years) from China.”

The underlying mechanisms and the relationship between loneliness and problematic mobile phone use in adolescents have rarely been studied.
“Previous studies have focused mainly on the direct relationship between loneliness and PMPU in college students, but the underlying mechanisms (e.g., how loneliness is associated with PMPU) and the relationship between loneliness and PMPU in adolescents have rarely been studied.”
The paper relies on this without support.
The relationship between escape motivation, self-control, and problematic mobile phone use is the same during the COVID-19 pandemic and in normal life before it.
“Thus, whether it's during the COVID-19 pandemic or in normal life before it, self-control could alleviate the influences of escape motivation on PMPU.”
The paper relies on this without support.
The cross-sectional associations reflect the hypothesized temporal sequence in which loneliness precedes escape motivation, which precedes problematic mobile phone use.
“Escape motivation fully, rather than partially mediated the effects of loneliness on PMPU.”
The paper relies on this without support.
The sample is representative of adolescents during the COVID-19 pandemic.
“Loneliness was significantly and positively associated with PMPU during the COVID-19 pandemic, thus supporting H1.”

In the citing paper
“Two studies found significant positive associations between loneliness and technology-based pathologies including mobile addiction [45], social media disorder [42], excessive game addiction, and pathological game addiction [59], although these latter two associations varied by children versus adolescents.”

Escape-motivation path has an incompatible t statistic
MinorFor the escape-motivation-to-PMPU path, dividing the reported coefficient of 0.44 by its standard error of 0.03 gives about 14.67, not 18.47. Even allowing both inputs to have been rounded to two decimal places cannot produce the reported t statistic.

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 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (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.
