Although children wish to be included in their own healthcare, they recognize a gap between their right to be heard and their ability to become involved. Despite adaptation of medical consultation styles which suit a more patient-centered approach, data on the current state of child participation in clinical encounters are missing. We aimed to assess actual child participation in a Dutch pediatric clinic. Children aged 4–18 years visiting a pediatric outpatient clinic for consultation after general practitioner’s referral were included. Sixteen consultations of six pediatricians were recorded and transcribed verbatim. Quantitative measurement included word count and speech turn; conversation analysis with qualitative appraisal provided data on participatory behavior. Quantitative child participation equaled parent participation in turns (28% vs 29%, respectively), but remained limited in words (relative contribution 11% for child, 23% for parent and 66% for pediatrician). Children spoke on average six words per speech turn. Child age correlated positively with participation in words (p = 0.022, r = 0.566) and turns (p = < 0.001, r = 0.746). Children were mostly involved during social history taking, introduction, and physical examination but did not actively speak during the decision-making process. Children took an active role by instigating talks. Qualitative facilitators included appropriate language and verbal or non-verbal child allocated turns. Adults involved children by asking them questions and verifying their opinions or plans with the child. Teenagers participated most during the entire consultation, while younger children were more likely to lose their focus by the end of the conversation.Conclusion: Despite increased turn taking, children’s verbal participation remains low in pediatric consultations. If pediatricians and parents maintain a triadic conversation style throughout every stage of the medical encounter, child participation may increase.What is Known:• Verbal child participation varies between 4 and 17%, measured in turns, words, speech time, or utterances.• Child participation is limited to social talk, laughter, and providing medical information.What is New:• Child speech turns equal parental speech turns (28%), but average relative word count remains low (11%).• Three percent of the children’s turns are defined a “contributing in decision making, giving their opinion or give consent,” which equals three turns per consultation.
