- | ====== ADHD (QADH) ====== | ||
- | |||
- | ADHD is the name of an [[additional assessments|additional questionnaire]] on prevalence and co-morbidities of [[https://en.wikipedia.org/wiki/Attention_deficit_hyperactivity_disorder|attention deficit hyperactivity disorder]] among Lifelines participants. | ||
- | Implementation of this questionnaire in [[start|Lifelines]] was initiated by the [[https://www.umcg.nl/NL/UMCG/Afdelingen/Universitair_Centrum_Psychiatrie/Paginas/default.aspx|University Center of Psychiatry]] of the UMCG, as part of the EU Horizon-2020 [[https://coca-project.eu|CoCa]] (co-morbid conditions of ADHD) project.\\ | ||
- | |||
- | The collected ADHD data is currently under embargo. Please contact the Lifelines data managers at [[data@lifelines.nl]] for more information. | ||
- | ===== Protocol ===== | ||
- | |||
- | QADH aimed to measure the rate of ADHD within the Lifelines cohort, as well as potential co-morbidities such as autism spectrum problems, mood disorders, substance abuse, and sleeping problems. | ||
- | QADH contained separate but overlapping digital questionnaires that were tailored to three groups of Lifelines participants, plus a group of significant others: | ||
- | |||
- | - [[Children]] 4-12 years old. Parents filled in the complete questionnaire. In this group, the questionnaire also included a [[QDCD|Developmental Coordination Disorder]] questionnaire. | ||
- | - Adolescents 13-17 years old. Adolescents filled in their own questionnaire, except for items on [[ADHD Rating Scale|ADHD]] and [[Social functioning (ASBQ/CSBQ)|autism spectrum problems]] which were filled in by their parents. | ||
- | - Adults of 18+ years old filled in their own questionnaires. | ||
- | - For adult participants, items on [[ADHD Rating Scale|ADHD]], [[cognition (general)|cognition]], [[Social functioning (ASBQ/CSBQ)|autism spectrum problems]] and [[aggression (ASR/ACBL)|aggression]] were also filled in by a significant other such as a parent, partner, or similar. | ||
- | |||
- | Rationale for the use of parental or other informants: self-insight is limited for neurodevelopmental problems such as ADHD or autism spectrum, and a second informant is required to rate the presence of the symptoms in order to meet the existing publication standards regarding valid diagnostic information. | ||
