Associations of Problematic Smartphone Use and Smartphone Screen Time With Eating Disorder Psychopathology in Non-Clinical Samples: A Systematic Review Background: The ubiquitous use of smartphones has given rise to maladaptive patterns of use, often termed “problematic smartphone use” (PSU), which disproportionately impacts children and young people and is associated with poor #MentalHealth. Emerging evidence suggests that patterns of smartphone use (eg, PSU and high smartphone screen time) may also influence eating patterns and contribute to symptoms associated with eating disorders (ED), although the nature of this relationship remains poorly understood. Objective: The aim of this systematic review was to examine the association between PSU and ED psychopathology or ED-related outcomes (eg, body dissatisfaction, emotional eating, and food addiction) in clinical and nonclinical populations and explore potential moderators and mediators. Methods: This preregistered systematic review conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines searched 3 databases (PubMed, Embase, and Web of Science) for studies published after January 2011 reporting data on PSU and ED psychopathology. Results: Thirty-five studies met the prespecified eligibility criteria, with almost all reporting cross-sectional data in nonclinical populations (n=52,584; mean age 17.0, SD 5.5 years). Most studies were assessed as being of good quality (n=28, 78%) according to a modified version of the Newcastle-Ottawa Scale. In these nonclinical samples, the vast majority of studies reported a positive association between PSU and ED psychopathology, which was largely consistent across age groups and countries. Identified mediators of this relationship included greater emotional regulation difficulties and anxious and #depressive symptoms. Positive associations were also found across studies between PSU and several ED-related outcomes including food addiction, body dissatisfaction, uncontrolled eating, and emotional overeating. Daily smartphone screen time was consistently related to higher ED psychopathology. According to a GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) assessment of the evidence, most outcomes were rated as low certainty, largely due to the cross-sectional nature of evidence, which contributed to a high risk of bias. Conclusions: PSU and greater daily smartphone screen time are associated with higher ED symptoms, body image dissatisfaction, and broader disordered eating behaviors. Due to a paucity of studies in clinical populations, these conclusions are generalizable only to nonclinical populations (ie, those without a formal diagnosis of an ED). Further longitudinal research in clinical populations is needed to fully contextualize the impact of PSU and smartphone screen time on ED risk and severity.

Excessive smartphone use isn't just about time. New study finds “heavy process use” (≥4h/day use, entertainment, social media) strongly predicts problematic smartphone use in students. Female and younger users most at risk.

Perceived #Digital Well-Being Scale in the United States and United Kingdom: Psychometric Validation Study Background: #Digital well-being encourages balanced mobile use. The Perceived #Digital Well-Being in Adolescence Scale (PDWBA) scale measures this in adolescents but was validated only in Slovenia, raising questions about its relevance for other age groups and cultural contexts. Objective: This study had three primary objectives: (1) to confirm the three-factor structure of an English version of the PDWBA—renamed the Perceived #Digital Well-being Scale (PDWS)—in samples of young adults from the United States (USA) and the United Kingdom (UK; (2) to examine the associations between PDWS dimensions and participants’ sociodemographic characteristics; and (3) to explore the relationships between PDWS scores and patterns of smartphone use. Methods: A total of 1,854 young adults from the USA and the UK (ages 18–25; M = 22.4, SD = 2.1); 892(48.1 %) female, 872(47.0 %) male, 90(4.9 %) non-binary participated in an online survey including the PDWS, #Digital flourishing and #Digital stress measures. Data were analyzed using descriptive statistics, confirmatory factor analysis, correlations, t-tests, chi-squared tests, and moderation-mediation analysis. Results: The smartphone screen time use and the smartphone time use for non-essential activities was statistically higher in the USA sample than in UK sample (M = 6.95 vs M = 6.13, t = 4.97, P

Objectively Measured Smartphone Use and Nonsuicidal Self-Injury Among College Students: Cross-Sectional Study Background: The impact of smartphone use on #MentalHealth is being rigorously debated. Some questionnaire-based research suggests that smartphone use correlates with non-suicidal self-injury (NSSI), self-reported data seem unlikely to capture actual smartphone use precisely, requiring objective measures to advance this field. Objective: To examine whether objectively measured smartphone use was associated with NSSI among college students. Methods: This multicenter cross-sectional study was conducted from 2022 to 2024, enrolling college students from 559 classes across six universities in China. NSSI was measured by the Ottawa Self-Injury Inventory (OSI) including 10 items of NSSI without suicidal intent within the past month. Participants answering “ever” were classified as having NSSI. Objectively measured smartphone screen time and number of smartphone unlocks were obtained from screenshots of smartphone use records. The association between objectively measured smartphone use and NSSI was analyzed using binary logistic regression models and restricted cubic splines (RCS) regression. Results: Of 16 668 included participants, 627 (3.8%) reported NSSI. Mean (SD) smartphone screen time and number of smartphone unlocks were 48.8 (28.8) hours/week and 271.6 (291.0) times/week. The models adjusted for different factors showed significant association between smartphone use and NSSI. Compared to participants with 0~21 hours/week of smartphone screen time, those with ≥63 hours/week of smartphone screen time had a higher odds of NSSI (OR=1.63; 95% CI, 1.32-2.01). Likewise, compared to participants with 0~50 times/week of smartphone unlocks, those with ≥400 times/week of smartphone unlocks had a higher odd of NSSI (OR=1.53; 95% CI, 1.25-1.88). No significant NSSI risk increases was observed for participants with 21~42 hours/week and 42~63 hours/week of smartphone screen time, nor for those with 50~150 times/week and 150~400 times/week of smartphone unlocks. Moreover, RCS analyses showed that the increasing risk of NSSI was associated with elevated smartphone screen time and number of smartphone unlocks. Conclusions: These findings emphasize that ≥63 hours/week of smartphone screen time and ≥400 times/week of smartphone unlocks are risk factors for NSSI among college students, and interventions targeting NSSI should consider the #Apparent association with smartphone use.
