This OSF page displays the dataset, code and output for the Paper "Behavioural Inhibition, Negative Parenting and Social Withdrawal: Longitudinal Associations with Loneliness during Early, Middle and Late Adolescence", which has been accepted for publication by Child Development in December 2022. The paper can be found under http://doi.org/10.1111/cdev.13874. The following files are uploaded here 1. Dataset to reproduce results: **Dataset_raw.sav**. 2. R script: **Loneliness_Analyses_Final_2ndrevision.R** 3. Script with nicely formatted output: **Loneliness_Analyses_Final_2ndrevision_formatted.pdf** This script has 3 parts. - *Part 1*: Datapreparation and descriptives (including winsorizing of scores +/-3SDs) - *Part 2:* CFA Analyses to calculate factor scores for Parenting, Behavioral Inhibition, Withdrawal (Measurement part) - *Part 3*: Path Analyses to study Mediation and Moderated Mediation based on factor scores from part 2 (Stuctural Part) Previous versions of the code can be found in the folder "Previous versions": - *Subfolder "1_Submission":* In the initial submission, analyses were conducted in R and Mplus. That is why, here there are multiple different files with script and outputs (October 2021) - *Subfolder "2_Revision1":* After invitation to resubmission, we decided to do all analyses in R to improve reproducibility (March 2022) **Update December 2022**: After a second invitation to resubmission in July 2022, we added minor parts to the code as sensitivity analyses (e.g., scatterplots and checking consistency of the indirect effect). After this revision, the paper was accepted by Child Development. The paper can be found under: http://doi.org/10.1111/cdev.13874 If you have any questions or remarks about the analyses, please reach out to Dominique Maciejewski via dominique.maciejewski@ru.nl.
