Outcome Measures

Primary Outcomes (15)

  • Estimated intellectual functioning (Neurocognition)

    Is assessed using 2 or 4 subtasks of the Dutch translation of the Wechsler Intelligence Scale for Children-Fifth edition (WISC-V-NL \[8-16 years\]) or the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV-NL \[16-35 years\]), depending on the visual ability of the participant. The 'Verbal Comprehension Index' (VCI) is assessed in all participants using the verbal subtests 'Similarities' and 'Vocabulary'. The 'Perceptual Reasoning Index' (PRI) is assessed in all sighted participants using the subtests 'Matrix Reasoning' and 'Block Design'. Index scores are calculated (range 55-145; M=100, SD=10) and outcomes between 90-110 are considered average, \<89 below average to borderline and \>110 above average to highly gifted. Subscale outcomes (range 0-20; M=10, SD=2) between 8-12 are considered average, \<8 below average, and \>12 above average.

    This concerns a cross-sectional study meaning that a neuropsychological assessment is carried out only once on all participants during the course of the study until study completion, approximately in 2027.

  • Processing speed (Neurocognition)

    Vienna S2 'Auditory Reaction Time' is only assessed in all participants. Additionally, Vienna S1 'Visual Reaction Time' and S3 'Combined \[visual-auditory\] Reaction Time', and subtasks 'Digital Symbol Coding' and 'Symbol Search' of the WISC-V-NL or WAIS-IV-NL will be assessed in sighted participants as well. Outcomes of the VTS will be calculated in T-Scores (range 20-80; M=50, SD=10), where a T-score between 40 and 60 is considered average, \<40 below average and \>60 above average. A WISC-V-NL or WAIS-IV-NL Index score will be calculated (range 55-145; M=100, SD=10) and is considered average between 90-110, \<89 as below average to borderline, and \>110 as above average to highly gifted. Subscale outcomes (range 0-20) between 8-12 are considered average, \<8 below average and \>12 above average.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion.

  • Memory (Neurocognition)

    In all participants, encoding and retrieval of verbal information will be assessed using the Rey- Auditory Verbal Learning Test (RAVLT). Working memory will be assessed using the subtests 'Digit Span' of the WISC-V-NL (8-16 years) or WAIS-IV-NL (17-35 years) resulting in the 'Working Memory Index' (WMI). RAVLT outcomes will be calculated in T-Scores (range 20-80), where a T-score between 40 and 60 is considered average, \<40 below average and \>60 above average. WISC-V-NL or WAIS-IV-NL Index scores will be calculated (range 55-145; M=100, SD=10) and outcomes between 90-110 are considered average, \<89 below average to borderline and \>110 above average to highly gifted. Subscale outcomes (range 0-20; M=10, SD=2) between 8-12 are considered average, \<8 below average, and \>12 above average.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion.

  • Verbal fluency (Neurocognition)

    Verbal fluency will be assessed in all participants using the Semantic condition of the Dutch translation of the subtask Word Production of the Developmental Neuropsychological Assessment (NEPSY-III-NL \[age 8-12 years\]) or the Word Fluency Test (WFT \[13-35 years\]), a Dutch translation of the Controlled Oral Word Association Test (COWAT)). NEPSY-III-NL outcomes will be calculated in norm scores (range 0-20; M=10, SD=2), where outcomes between 8-12 are considered average, \<8 below average and \>12 above average. Outcomes of the WFT will be calculated in T-Scores (range 20-80; M=50, SD=10), were a T-score between 40 and 60 is considered average, \<40 below average, and \>60 above average.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion.

  • Visual Motor Integration (Neurocognition)

    Visual Motor Integration will be assessed in sighted participants only, using the Visual-Motor Integration (VMI), Visual Perception (VP) and Motor Coordination (MC) of the Beery-Buktenica Developmental Test of Visual-Motor Integration, 6th Edition, Beery-VMI. Standard scores (range 48-155; Mean=100, SD=15) will be calculated, as well as T-scores (range 55-145; M=50, SD=10). Standard scores between 85-115 are considered average, \<85 below average to borderline, and \>115 above average to highly gifted. T-scores between 40 and 60 are considered average, \<40 below average, and \>60 above average.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion.

  • Sustained Auditory Attention (Neurocognition)

    Sustained auditory attention will be assessed in all participants using the subtask Score! of the Test of Everyday Attention for Children (TEA-Ch \[6-16 years\]; Publication date 2004) or the Elevator task of the Test of Everyday Attention (TEA \[17-35 years\]; Publication date 1994). Regarding the TEA-Ch, norm scores (range 1-19; M=10, SD=2) will be calculated, whereas outcomes between 8-12 are considered average, \<8 below average, and \>12 above average. The Elevator task of the TEA has 7 subsets, the participants receives one point per correct subset (max=7). An outcome of 7 is considered 'Normal', 6 is considered 'Subclinical Abnormal', and \<5 is considered 'Clinical Abnormal'.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion.

  • Executive functioning (Neurocognition)

    The Executive functioning (EF) tasks will be assessed in sighted participants only. The Stroop Color Word Test of the Delis-Kaplan Executive Function System (D-KEFS; Publication date 2007) measures selective visual attention, cognitive flexibility, inhibition and processing speed. The Trail Making Test (TMT) of the D-KEFS (publication data 2007) assesses attention, visual screening and cognitive flexibility. Scale scores will be calculated (range 0-20; M-10, SD=2) and scores between 8-12 are considered average, scores \<8 are considered below average, and scores \>12 above average.

    This concerns a cross-sectional study and data will be collected until April 2027. The neuropsychological assessment is carried out only once on all participants during the course of the study until study completion

  • Anxiety (Psychosocial functioning)

    Anxiety (proxy 5-16 years and self-report 8-35 years) is assessed using a digital Patient Reported Outcomes Measurement Information System (PROMIS), computer adaptive testing (CAT) questionnaire (using the Dutch KLIK portal \[in Dutch Kwaliteit van Leven in Kaart/Mapping Quality of Life\]). A standard Total Scale score (range 0-100) of 0-59 indicate no anxiety symptoms, between 60-69 subclinical anxiety symptoms, and \>70 clinical anxiety symptoms.

    This concerns a cross-sectional study. Digital questionnaires will be assessed (if applicable) within two weeks of the neuropsychological assessment, only once on all participants during the course of the study until study completion (expected 2027).

  • Depression

    Depression (proxy 5-16 years and self-report 8-35 years) is assessed using a digital PROMIS-CAT questionnaire (using the Dutch KLIK portal).

A norm score of \<29 is considered having poor peer relations, between 29 and 39 suboptimal peer relations, and \>39 having no peer relation problems.

    This concerns a cross-sectional study. Digital questionnaires will be assessed (if applicable) within two weeks of the neuropsychological assessment, only once on all participants during the course of the study until study completion (expected 2027).

  • Perceived neurocognitive functioning (Psychosocial functioning)

    Perceived neuropsychological functioning (self-report 8-35 years) is assessed using a digital PROMIS-CAT questionnaire (using the Dutch KLIK portal). The questionnaire consists of 7 questions related to perceived problems regarding attention, focus, memory and reading comprehension. Questions are answered on a 4-point Likert scale (1=never, 2=sometimes, 3=often, 4=most of the time). Due to absence of standard data, standardized outcomes cannot be calculated. Outcomes of participants will be compared to each other, with a low score indicating good perceived cognitive functioning and a high score indicating declined perceived cognitive functioning

    This concerns a cross-sectional study. Digital questionnaires will be assessed (if applicable) within two weeks of the neuropsychological assessment, only once on all participants during the course of the study until study completion (expected 2027).

  • Participation and Activity (Psychosocial functioning)

    Participation and activity (proxy 0-16 years and self-report 8-35 years) is assessed using the digital questionnaire Participation and Activity Inventory for Children and Youth (PAY-CY, publication date 2019, \[using the Dutch KLIK portal\]). Due to absence of standard data, outcomes (range 0-100) of participants will be compared to each other, with a high score indicating the absence of or fewer obstacles to activity and participation in daily life and a low score indicates much perceived obstacles. Outcomes relate to 'Activity and participation'. Additionally, 'Sensory functioning' and 'Parental component' is also assessed in the proxy questionnaires.

    This concerns a cross-sectional study. Digital questionnaires will be assessed (if applicable) within two weeks of the neuropsychological assessment, only once on all participants during the course of the study until study completion (expected 2027).

  • Trauma (psychosocial functioning)

    Post-traumatic stress disorder (PTSD; proxy 3-16 years/ self-report 8-35 years) is assessed using the Dutch translation of the Child and Adolescent Trauma Screener (KJTS, in Dutch: Kind en Jeugd Trauma Screener \[3-18 years\]) or the PTSD Checklist for the DSM-5 (PCL-5 \[18-35 years\] using the Dutch KLIK portal)). Standard outcomes of the KJTS (range 0-60) regards 'Total Score', whereas \<15 is considered within normal limits, 15-19 subclinical development of PTSD and \>20 clinical development of PTSD. Regarding PCL-5, participants report a traumatic event ('Criteria A'). Standard outcomes are calculated in a 'Total Score' and sub scores corresponding to the DSM-5 criteria: 'Criteria B' (intrusive symptoms), 'Criteria C' (persistent avoidance), 'Criteria D' (negative alterations), and 'Criteria E' (arousal and reactivity). A Total Score (range 0-80) between 0-27 indicates no PTSD symptoms, between 28-32 subclinical PTSD development, and a total score of \>33 development of clinical PTSD.

    This concerns a cross-sectional study. Digital questionnaires will be assessed (if applicable) within two weeks of the neuropsychological assessment, only once on all participants during the course of the study until study completion (expected 2027).
