Infant Behavior Questionnaire Revised (IBQ-R)

The Infant Behavior Questionnaire (IBQ) and Infant Behavior Questionnaire-Revised (IBQ-R) were designed to measure temperament in infants between the ages of 3 and 12 months. The IBQ assesses dimensions of temperament, such as activity level, soothability, fear, distress to limitations, smiling and laughter, and duration of orienting, among others. The items on the IBQ ask parents to rate the frequency of specific temperament-related behaviors observed over the past week (or sometimes two weeks). The revised version referred to as the IBQ-Revised (IBQ-R) comes in a Short version (91 items; 14 scales) or a Very Short version (37 items; 3 broad scales).

In RADAR G3, the revised short version of IBQ was used (IBQ-R-S: 91 items), assessing the following subscales: Activity Level (7), Distress to Limitations (7), Approach (6), Fear (6), Duration of Orienting (6), Smiling and Laughter (7), Vocal Reactivity (7), Sadness (6), Perceptual Sensitivity (6), High Intensity Pleasure (7), Low Intensity Pleasure (7), Cuddliness (6), Soothability (7), Falling Reactivity/Rate of Recovery from Distress (6) Surgency/Extraversion (6), Negative Affectivity (4), and Orienting/Regulation (4).

Research on Adolescent Development and Relationships Cohort study

Purpose	The goal of RADAR is to investigate the normal, but also problematic development of adolescents. During high school, adolescents experience a period of major changes, such as changes in classmates and friends. But it is also a period of bodily changes, changes in behavior and in becoming more independent. During adolescence, there is an increased risk of depression and anxiety. Sometimes, antisocial behavior increases as well. Adolescence is therefore a period in which some adolescents develop problems, but others don’t. In RADAR, we investigate which factors are associated with a healthy and a problematic development of adolescents. By providing reliable information about possible causes and risk factors for developing problem behavior, support programs and interventions can be modified to become more effective.

Time method	Longitudinal
Universe	The participants of RADAR were recruited from randomly selected schools in the center and west of the Netherlands and consist of three groups: RADAR Young, RADAR Old and RADAR G3 (the next generation). RADAR Young consists of 497 adolescents of Dutch descent who were 12 years old at the start of RADAR. RADAR also followed 190 Moroccan adolescents aged 12 to 17. This group no longer participates in RADAR. RADAR Old consists of 233 adolescents of Dutch descent, who were 15 years old at the start of RADAR. RADAR G3 consists of RADAR participants who will or have become parents of a child younger than 7 years old themselves. Parents of a step-, adopted or foster child are also invited to participate in RADAR G3.

Measure was collected within the following cohort(s):

RADAR: Third Generation Cohort

Alternate title	RADAR G3, RADAR Third Generation
Description	Since 2013, the target and sibling participants in RADAR-Young and RADAR-Old who will become a parent or who have children are invited to participate with one of their children in additional data collection centering around RADAR-G3: the next generation. Four waves of data collection are currently conducted: in infancy, toddlerhood, the preschool years, and middle childhood. Participants and their partner fill out questionnaires about their child’s temperament, developmental milestones, psychosocial adjustment, and child-rearing when their 3rd generation child is 3 months, 2 years, 4.5 years and 7 years old. In addition, a home visit is conducted when the child is 2.5 years old and 7.5 years old, during which parent-child interaction tasks, and child social competence and self-regulation tasks are administered. A school assessment takes place at age 5, when teachers are asked to fill out a questionnaire about the child’s psychosocial adjustment.
Purpose	RADAR - The Next Generation aims to model a) three-generational continuity and discontinuity in interpersonal relationships and behavior within families, b) continuity and discontinuity between G1-G2 parenting and G2-G3 parenting, and c) test for situational and individual moderators that make or break continuity between generations.
