Behavioral and psychological correlates of problematic smartphone use in street ketamine users.
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile problematic smartphone use screening tools are widely used and increasingly evaluated in student populations, their applicability and clinical stability across diverse groups-particularly those with comorbid substance use-remain unclear. Moreover, the overlap between problematic smartphone use and internet gaming disorder has not been well established in clinical contexts. This study explores the behavioral and psychological characteristics associated with problematic smartphone use, focusing on its relationship with online gaming behaviors among ketamine users referred for court-ordered addiction treatment.
methodsThe study involved 233 participants diagnosed with ketamine use disorder. Participants reported their daily smartphone use and primary usage purposes. Ketamine dependence was assessed using the Chinese version of the Severity of Dependence Scale. Emotional distress was evaluated using the Brief Symptom Rating Scale and Generalized Anxiety Disorder 7-Item Scale. Attention-deficit/hyperactivity disorder (ADHD) symptoms were assessed using the Adult ADHD Self-Report Scale (ASRS-V1.1). Problematic smartphone use risk was evaluated using the Short Form of the Problematic smartphone use Inventory (SPAI-SF). Logistic regression was used to analyze factors related to problematic smartphone use risk.
resultsThe problematic smartphone use risk group reported significantly longer daily smartphone usage (odds ratio [OR]: 1.64; 95% confidence interval [CI]: 1.29-2.08), higher ASRS-V1.1 scores (OR: 1.14; 95% CI: 1.05-1.23), and a greater likelihood of using smartphones for online gaming (OR: 2.26; 95% CI: 1.19-4.29).
conclusionsExcessive smartphone use in ketamine users is closely linked to online gaming, and ADHD symptoms may increase the risk of problematic smartphone use in this population.
