-====== 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/​ABCL)|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.
