BTPS-EXP 47 Sample and procedure Between April 2011 and June 2013, parents/caregivers of children aged 4-18 years old, along with children aged 12 years and over, were invited to participate in either the care or the community sample of TakeCare [26, 27]. For the care sample, 2664 children and their parents/caregivers were recruited via the main psychosocial care organizations for children in the northeast of the Netherlands, that is, preventive child health care, child and adolescent social care, and mental health care. In the Netherlands, children enter psychosocial care via either their general practitioner, the youth care office, or preventive child health care. The general practitioner and doctors and nurses in preventive child health care, may provide light parenting support or refer to more specialized care, that is, either child and adolescent social care, which is primarily provided by child (social) workers, or mental health care, which is primarily provided by child psychologists and psychiatrists [28]. Children with insufficient understanding of Dutch, living outside the northern region, or following special education because of intellectual disability were excluded ( N =223). Of the eligible 2441 respondents, 1382 participated, that is, either the child and/or the parent (response 56.6%). Differences between respondents and non- respondents were small regarding age, gender, degree of urbanization, and psychosocial problems, with Cohen’s effect sizes ranging from 0.01 (age) to 0.12 (degree of urbanization). The community sample ( N =1025) concerned a stratified random sample of school children, obtained via five primary schools, two secondary schools, and one school for intermediate vocational education, recruited by taking into account the distribution of children across the study region according to age, gender, socioeconomic position, and degree of urbanization. Of these, 77 were excluded. Of the eligible 948 respondents, 666 participated (70.3%). Differences between respondents and non-respondents were small in terms of age, gender, degree of urbanization, and psychosocial problems, with effect sizes ranging from 0.02 (psychosocial problems) to 0.08 (degree of urbanization). Data were obtained from parents/caregivers and adolescents via web-based or paper questionnaires at the moment of entry into the study, which was, for the care sample, at the moment of the child’s care enrolment. If required, we provided assistance in filling out the questionnaire. Measures Parents’ and adolescents’ expectations of barriers to care were measured with the BTPS- exp [20, 21], translated into Dutch [29]. Three certified translators translated the questionnaire instructions, item content, and response options from English to Dutch.
