Public replication dataset for: Perceived adolescent insecure attachment with mothers and fathers: links with food addiction, eating disorders, and weight status

This public replication dataset contains anonymised analysis-ready self-report data from 3,677 Czech adolescents aged 15–19 years. It supports reproduction of the inferential statistical analyses reported in the related publication on perceived insecure attachment to mothers and fathers, food addiction, eating-disorder symptoms, and weight status. The dataset includes the analytical predictors and outcomes required for the reported Pearson correlations, hierarchical linear regression models, and logistic regression models: age, sex, ethnicity, family structure, parental education, maternal/paternal attachment avoidance and anxiety, food-addiction score, eating-disorder score, BMI score, and BMI-category indicators. Direct identifiers and high-risk contextual variables were removed, including original participant code, school/city, region, exact administration date, month/year of birth, raw height and weight, free-text responses, religion variables, and questionnaire blocks not required for reproducing the main inferential analyses. Additional non-public source data are not openly available due to re-identification risk and may be requested from the corresponding author subject to institutional and ethical approval.
