Temptation as a key driver between affective states and usage outcomes of problematic usage of the Internet: A 14-day ambulatory assessment study.
Article in PloS one, 2026. 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
Theoretical models of problematic usage of the Internet (PUI) assume that stress and negative mood can trigger cravings and desires as central drivers to use certain online applications that are expected to provide pleasure and relief, which increases the likelihood of use. Learning and reinforcement mechanisms can result in increased and uncontrolled Internet use, that manifests itself in the form of, for example, neglecting important areas of life like relationships or work. To test these associations in a natural environment, we conducted a 14-day ambulatory end-of-day assessment together with a diagnostic interview at baseline to identify different severity levels of PUI. The sample (N = 900) was part of a multi-center study (FOR2974) including participants who engaged in at least one of the following online activities: gaming, pornography use, social network use, or buying-shopping in either a non-problematic (n = 419), risky (n = 242), or pathological (n = 239) way. The adherence rate was about 88%. The data were analyzed using ANOVAs, generalized linear mixed modeling (GLMM), and multigroup multilevel structural equation modeling (MG-ML-SEM). In participants experiencing more severe PUI, ANOVAs revealed greater neglect of other areas of life (f = 0.531), longer use times (f = 0.442), and more stress (f = 0.220-0.248) as well as worse mood in daily life (f = 0.220-0.237). Overall, the variables and random effects in the GLMM explained R²conditional = 79.9% (R²marginal = 22.6%) of variance in the prediction of daily usage with temptation as primary within-person effect (OR=2.53) and PUI severity as between-person effect (OR = 0.41 to 11.33) being the main predictors. Results of the MG-ML-SEM indicate that pleasure and relief are reinforcing factors for continued use of the Internet with temptation as the central main driver (strongest effect sizes), as theoretically expected. With the extensive sample, the longitudinal approach, and the robust statistical methods, it shows that assumptions of common theoretical models for PUI can also be found in everyday life.
