Investment Models Scale (IMS)

The Investment Models Scale (IMS) consists of two sets of items associated with the four central constructs of the Investment Model (IM): facet items and global items. Facet items measure the antecedents of commitment - satisfaction, quality of alternatives and investment size. These facet items are included in the IMS to activate in memory and illustrate each of the respective constructs, in order to facilitate its correct apprehension and the response to the global items. The set of global items measure satisfaction, quality of alternatives and investment size, as well as the commitment level toward the relationship.

Measure was collected within the following cohort study:

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 Early 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 3-4 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 Early Childhood Cohort is twofold: 1. To investigate the development of social competence and behavioral control in children between 3 and 9 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):

ECC - T1 Wave

Wave alternate title	ecc1, ecc_ses-w01
Short description of the wave	Wave 1 of the Early Childhood Cohort consisted of parent-reported online questionnaires and a home visit in which 3-5 year old children from about 230 families were observed while performing several tasks. Additionally, participants were asked to take measurements (including collecting physiological data) on their own for several days after the home visit.

ECC - T2 Wave

Wave alternate title	ecc2, ecc_ses-w02
Short description of the wave	Wave 2 of the Early Childhood Cohort consisted of parent-reported online questionnaires and a lab visit in which 4-6 year old children from about 200 families were observed while performing several tasks. During some of the tasks, brain activity was measured by means of electroencephalography (EEG). Additionally, physiological samples were taken (e.g., hair and DNA samples). Participants were also asked to take measurements on their own at home for several days after the lab visit. Furthermore, to experimentally examine social enrichment, we included a parenting intervention, which allows investigating the causal effects of parenting on social development. Between the 2nd (ECC - T2) and 3rd (ECC - T3) measurement, 40% of the sample received a video feedback intervention to promote positive parenting and sensitive discipline (VIPP-SD).
