Eveningness has been associated with maladaptive eating patterns such as food addiction and night eating syndrome, with mindful eating considered a critical factor in these associations.</p><p><strong>Objective: </strong>The aim of this study was to examine the direct relationships among eveningness, night eating syndrome, and food addiction, and to investigate the mediating role of night eating syndrome and the moderating role of mindful eating in these associations.</p><p><strong>Methods: </strong>This exploratory cross-sectional study was conducted with 490 adults. Participants completed validated measures including the Yale Food Addiction Scale (YFAS), Night Eating Questionnaire (NEQ), the Morningness-Eveningness Questionnaire (MEQ^c), and the Mindful Eating Questionnaire (MEQ^m). To identify predictors and risk factors of food addiction and night eating syndrome were examined using binary logistic regression and hierarchical linear regression models. Mediation and moderation analyses were conducted using the PROCESS macro (Model 4 and Model 1). Model 4 tested the indirect pathways from chronotype to food addiction through night eating syndrome.

Linear regression analyses indicated that greater night eating syndrome symptom severity predicted higher food addiction symptom counts (B = 0.026, p < 0.001), whereas mindful eating predicted fewer food addiction symptoms (B = -3.400, p < 0.001). Logistic regression further showed that night eating syndrome (OR = 1.060, p < 0.001) increased the risk of food addiction, whereas mindful eating (OR = 0.152, p < 0.001) reduced it. Path analyses indicated that night eating syndrome mediated the association between eveningness and food addiction, whereas mindful eating partially moderated the relationship between night eating syndrome and food addiction.</p><p><strong>Conclusions: </strong>This study shows interrelations among chronotype, night eating syndrome, and mindful eating in relation to food addiction.

We illustrate the workflow using clinical case data from patients with eating disorders, to capture temporal patterns that cannot be detected with conventional network analysis techniques, as these require more intensive time-series data. Key advantages include its applicability to non-stationary data, flexibility in handling irregular time intervals, and reduced reliance on frequent assessments, which patients often cannot maintain due to the burden. We also discuss some of the limitations such as noise, scaling decisions and lack of Granger causality associations. Finally, we outline directions for future research.
