Online Acts Questionnaire

The Online Acts Questionnaire is a self-developed questionnaire that consists of 16 items assessing behavior of children on social media, through topics such as prosocial behavior and social media participation. Items include, for example, "I am popular on social media", "I am friendly for others on social media", and "I often like posts from someone I know on social media, like a friend".

Leiden Consortium on Individual Development Cohort study

Purpose	The primary aim of the Leiden-CID study is to increase our understanding of the developmental pathways of social behavior and behavioral control that are important to the development of social competence, from early childhood to young adulthood. If we better understand the mechanisms involved in developmental processes of social competence, this allows us to understand optimal conditions that add to the well-being of developing individuals.

Universe	Same-sex (51% girls), mono- and dizygotic twins between 3 and 16 years old, and their parents (primary parent and other parent). Children in the early childhood cohort (ECC; N = 476) were followed from 3 to 9 years of age, whereas children in the middle childhood cohort (MCC; N = 514) were followed from 7 to 16 years. All participants lived in the Netherlands (within two hours travel time from Leiden). The majority of the participants were Caucasian (ECC: 88%, MCC: 90%). Additionally, participants had both a low, middle-, as well as a high socio-economic status (ECC: 7–37–56%, MCC: 9–46–45%). To be eligible to participate, potential participants had to be fluent in Dutch, their parents and grandparents had to be born in Europe (because of genetic analyses), and the twins should have the same gender. Excluded were children with a congenital disability, psychological disorder, chronic illness, hereditary disease, or a visual or hearing impairment if the disorder disabled the child from performing the behavioral tasks or from participating in the (f)MRI or EEG/ERP measure. Children with a previously diagnosed intellectual disability (IQ < 70), history of neurological or psychiatric illness and/or use of psychotropic medications were also excluded. Lastly, contraindications for fMRI, including metal implants, heart arrhythmia, and claustrophobia would lead to exclusion as well.

Description	The Middle Childhood Cohort of the Leiden Consortium on Individual Development (L-CID) is a large-scale longitudinal intervention study in which +- 250 families with same-sex twins, aged 7-8 at wave 1, are followed over a six year period. Annual assessments consist of alternating lab- or home visits during which behavioral and neurobiological data are collected. The collected data allow, among others, for testing which child characteristics shape the effect of (manipulated) environmental factors. The aim of the Middle Childhood Cohort is twofold: 1. To investigate the development of social competence and behavioral control in children between 7 and 14 years old; 2. To dissect the reason why not all children are equally responsive to variations in the social environment.

Measure was collected within the following wave(s):

MCC - T6 Wave

Wave alternate title	mcc6, mcc_ses-w06
Short description of the wave	Wave 6 of the Middle Childhood Cohort consisted of a home visit that was performed digitally because of the Covid-19 pandemic. 12-14 year old children from about 160 families were observed while they performed tasks and they and their parents/caretakers filled out online questionnaires. Some of the originally planned tasks were dropped, because it was not possible to perform them during a digital visit. Participants also took measurements on their own at home.

MCC - T7 Wave

Wave alternate title	mcc7, mcc_ses-w07
Short description of the wave	Wave 7 of the Middle Childhood Cohort was added as an additional wave of data collection. It consisted of child-reported online questionnaires and a lab visit in which 14-15 year old children performed tasks and filled out more questionnaires. During some of the tasks, brain structure and activity were measured by means of (functional) Magnetic Resonance Imaging (MRI). Contrary to prior waves, this year only the children participated in the study, and not their parents.
