Waves	Young Netherlands Twin Register YS_5 MC 5.0 years From 1994-01-01 (ongoing)
Mode of collection	SelfAdministeredQuestionnaire
Analysis unit	Individual

Purpose	The research carried out by the Netherlands Twin Register focuses on the role of heritability in mental and physical health. For instance, the NTR investigates why some people become more easily depressed than others, or why certain people get diabetes while others do not. Other research areas include lifestyle and habits that influence health and disease, such as smoking, drinking and exercise.

Description	The Young Netherlands Twin Register (YNTR) consists of projects within the Netherlands Twin Register (NTR) that involve families with twins or other multiples under the age of 18.
Purpose	The purpose of the projects within the Young Netherlands Twin Register focus on the role of heritability in mental and physical health. For instance, the NTR investigates why some people become more easily depressed than others, or why certain people get diabetes while others do not. Other research areas include lifestyle and habits that influence health and disease, such as smoking, drinking and exercise.

Measure was collected within the following wave(s):

YS_5 Wave

Wave alternate title	YNTR survey age 5 YS_5
Short description of the wave	The YS_5 survey is sent to the mothers around the 5th birth year of the twins (mean age = 5.52 years, SD = 0.55 years). The survey includes items on child care and school, growth, zygosity, toilet training, asthma and eczema, fine motor coordination, language development, and problem behaviors as assessed by a short version of the Devereux Child Behavior Checklist (DCB). The booklet includes an extra section for fathers of twins to report about behavior problems. From 2011 onward, items on child care and school, living and family situation were updated and items on wellbeing were added. From the second half of 2015 the short form of the Childhood Behavior Questionnaire (CBQ) was added. From 2017 the surveys no longer have a separate section for the father.

The NTR was established in 1987 and has enrolled around 120.000 twins and a roughly equal number of their relatives. The majority of twin families have participated one or more times in survey studies on a host of epidemiological variables including social demography, personality, lifestyle, somatic and mental health, and subsamples took part in biomaterial collection (e.g. DNA) and dedicated projects for e.g. neuropsychological, biomarker, and behavioral traits. The recruitment into the NTR is fully inclusive without any restrictions on enrolment. The NTR is committed to actively seek the commitment of its participants to science and their continued involvement in NTR research by maintaining a website, electronic newsletters, and the MijnNTR portal that provides personalized feedback to participants. The NTR resources, e.g. the longitudinal phenotyping, the extended pedigree structures, and the multi-generation genotyping allow for future twin-family research that will contribute to gene discovery, causality modelling, and studies of genetic and cultural inheritance of behavioral traits and mental and physical health.
