Periodic Reporting for period 2 - Outside-In (Outside-in: How Bullying in Adolescence Gets Into The Mind and Under the Skin)
Berichtszeitraum: 2022-03-01 bis 2023-08-31
- Study 1 (WP1 and 2). We have collected the first three waves of data (wave 4 is currently ongoing) in a sample of 440 adolescents from 12 secondary schools. At each wave, we have collected different types of data.
First, consistent with WP2, at each wave we have collected: a) questionnaire data, with a specific focus on peer relationships and (mental) health, b) peer nomination data and c) autonomic nervous system activity at rest. Most importantly, at wave 1 (and currently in the ongoing wave 4) dried blood spots were collected. At the end of wave 4, all these samples will be used to carry out gene expression analyses.
Second, consistent with WP1, in the first three waves, we have carried out a daily life assessment in a subsample of participants. The Experience Sampling Method (ESM) was used to assess emotional processes and social experiences in participants’ daily life, each time over the course of 2 weeks. Moreover, at wave 1 and 3, physiological processes in daily life were also assessed, including saliva samples and autonomic nervous system activity. Cortisol levels have been assayed from all saliva samples for both waves of data collection. Initial descriptive analyses support the validity of this data which are now being prepared to examine the effects of bullying victimization on changes over time in diurnal cortisol levels.
- Study 2 (WP3). We have refined the study procedures and protocol and we have submitted an application to the medical ethical committee (2nd revision has being resubmitted). We plan to start this study within the next couple of months.
- In addition to these data collection activities, we have begun to use the ESM data at wave 1 to examine within-person dynamics between emotional processes, emotion regulation and (daily) peer experiences (see https://osf.io/ba7qy/ ). Moreover, using previously collected data, we have explored, preliminary, some of the proposed associations. For example, we have observed that peer victimization was associated – concurrently – with higher levels of negative affect, inertia of negative affect and stress appraisal in daily life (manuscript currently in preparation; see https://osf.io/56vsj/).
