Language and stuttering

Language development and stuttering contains questions about the child's speech development and the parent's and child's stuttering. Questions include, for example, "Have you ever stuttered?", "Did the stuttering bother you?", "Has your child ever stuttered?", "Does the child slowly repeat a sound from a sentence?", and "Does the child prolong a sound within a word?".

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.

YS_12 Wave

Wave alternate title	YNTR survey age 12 YS_12
Short description of the wave	The YNTR survey 12 was emailed to both parents of twins around the 12th birthday of the twins (mean age = 12.35 years, SD = 0.53 years). The survey targets the development of emotional and behavior problems as assessed by the Child Behavior Checklist 6-18 (CBCL). From 2001 onwards, the Conners’ Parent Rating Scale - Revised (CPRS-R) was also included. In addition, these surveys included items on zygosity, medical conditions, demographic characteristics, growth, sport and leisure activity of both children and parents (from 2003), and additional items on wellbeing (from 2008). In 2017 and 2018 the length of the questionnaire was shortened, the ASEBA Brief Problem Monitor (BPM) was used instead of the CBCL, and the 'cito survey' was added (see YS_CITO). From 2019, the questionnaire returned to its original length with CBCL and Conners items, and from 2020 the items on leisure time and on family and living situation were removed.

YC_BS2 Wave

Wave alternate title	Brain Scale measurement 2 YC_BS2, Brain Scale measurement t1, BrainScale age 12
Short description of the wave	The YC_BS2 project was the second measurement in the Dutch longitudinal Brain Scale study in which twins, their siblings and their parents were assessed at three year intervals. YC_BS2 took place three years after the baseline (YC_BS1) and targeted 12-year old twins (mean age = 12.2 years, SD = 0.3 years) born between 1995 and 1996 and their 9-18 year old siblings (mean age = 14.8 years, SD = 1.3 years) born between 1990 and 1997. The main aim of the Brain Scale project was to explore to what extent genetic and environmental factors explain individual differences in brain development and cognition. Data collection included psychometric IQ tests, a comprehensive neuropsychological testing protocol, and parental and self-ratings of behavioral and emotional problems. Physical maturation was measured through assessment of Tanner stages. Hormonal levels (cortisol, luteinizing hormone, follicle-stimulating hormone, testosterone, and estrogens) were assessed in urine and saliva. Brain scans were acquired using 1.5 Tesla Magnetic Resonance Imaging (MRI), which provided volumetric measures and measures of cortical thickness. Buccal swabs were collected for DNA isolation for future candidate gene and genome-wide analysis studies.

notes	Language development and stuttering contains questions about the child's speech development and the parent's and child's stuttering. Questions include, for example, "Have you ever stuttered?", "Did the stuttering bother you?", "Has your child ever stuttered?", "Does the child slowly repeat a sound from a sentence?", and "Does the child prolong a sound within a word?".

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. In the CID data catalogue, only the NTR projects for children and adolescents (<18 years of age) have been included.

YC_BS2 took place three years after the baseline (YC_BS1) and targeted 12-year old twins (mean age = 12.2 years, SD = 0.3 years) born between 1995 and 1996 and their 9-18 year old siblings (mean age = 14.8 years, SD = 1.3 years) born between 1990 and 1997. The main aim of the Brain Scale project was to explore to what extent genetic and environmental factors explain individual differences in brain development and cognition. Data collection included psychometric IQ tests, a comprehensive neuropsychological testing protocol, and parental and self-ratings of behavioral and emotional problems. Physical maturation was measured through assessment of Tanner stages. Hormonal levels (cortisol, luteinizing hormone, follicle-stimulating hormone, testosterone, and estrogens) were assessed in urine and saliva. Brain scans were acquired using 1.5 Tesla Magnetic Resonance Imaging (MRI), which provided volumetric measures and measures of cortical thickness. Buccal swabs were collected for DNA isolation for future candidate gene and genome-wide analysis studies.', 'wave_end_date_collection': '2009-01-01', 'wave_language': 'NL', 'wave_physical_data_product_description': 'Data collected through paper-and-pencil surveys have been scanned.
