In the proposed study, the investigators aim to investigate whether the existing ABAS-3 self-report questionnaire is suitable to be completed meaningfully by individuals who are perceived as having mild intellectual disability (55\<IQ\<85) based on cognitive impairment. Based on the participants' experiences and researchers' expertise, the investigators develop a 'more inclusive' self-report version. The investigators then look at the extent to which participants indicate that they understand this version better, based on user experiences and limited psychometric research. In doing so, the investigators also compare the outcomes of the self-report and informant-report variant.

A self-report questionnaire for assessing level of adaptive functioning
A self-report questionnaire for assessing level of adaptive functioning, adapted to the communication level of the participant
Koraal
Sittard, L, Netherlands
Scoring comprehension - T0
Degree to which the qualitative information provided by the participant aligns with the self-reported score on the original version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) questionnaire. Outcomes are 0, scores align, -1, scores are lower than answer would suggest, +1, score is higher than answer would suggest.
Time frame: At baseline (T0)
Scoring comprehension - T1
Degree to which the qualitative information provided by the participant aligns with the self-reported score on the original version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) questionnaire. Outcomes are 0, scores align, -1, scores are lower than answer would suggest, +1, score is higher than answer would suggest.
Time frame: Approximately 8 weeks after baseline (T1)
Text comprehension - cognitive interviews T0
Level of verbal understanding of questions in the questionnaire - qualitative analysis of answers from cognitive interviews during assessment of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition). Terms and concepts that were misinterpreted, participant utterings of confusion of statements of difficulty
Time frame: At baseline (T0)
Text comprehension - cognitive interviews T1
Level of verbal understanding of questions in the questionnaire - qualitative analysis of answers from cognitive interviews during assessment of an adapted version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition). Terms and concepts that were misinterpreted, participant utterings of confusion of statements of difficulty.
Time frame: Approximately 8 weeks after baseline (T1)
Comprehension of instructions - cognitive interviews T0
Level of verbal understanding of the instructions in the questionnaire - original version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition). Number of elements that were correctly identiefied (out of possible 10).
Time frame: At baseline (T0)
Comprehension of instructions - cognitive interviews T1
Level of verbal understanding of the instructions in the questionnaire - adapted version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition). Number of elements that were correctly identiefied (out of possible 10).
Time frame: Approximately 8 weeks after baseline (T1)
Overall difficulty score - T0
Likert scale rating of the overall difficulty of items of original version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) by participants (from 1. very easy - 5. very difficult)
Time frame: At baseline (T0)
Overall difficulty score - T1
Likert scale rating of the overall difficulty of items of adapted version of the ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) by participants (from 1. very easy - 5. very difficult)
Time frame: Approximately 8 weeks after baseline (T1)
Self-reported Adaptive Functioning - original ABAS-3 scores
The ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) is an observational scale that measures adaptive behaviour. Both self-report and informant report versions are available. In the context of the current study, a 30-item abbreviated version is used. Composite scores are calculated: a total score and three domain scores (conceptual, social and practical domain). Scores range from 0-90 for the total scale and 0-30 for each domain scale. Higher scores indicate better adaptive functioning.

Self-reported Adaptive Functioning - adapted ABAS-3 scores
The ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) is an observational scale that measures adaptive behaviour. Both self-report and informant report versions are available. In the context of the current study, a 30-item abbreviated version is used. Composite scores are calculated: a total score and three domain scores (conceptual, social and practical domain). Scores range from 0-90 for the total scale and 0-30 for each domain scale. Higher scores indicate better adaptive functioning. The second time participants complete the ABAS (approximately 8 weeks after baseline, T1), an adapted version is used, with language and design adapted to the comprehension level of participants according to the outcomes at baseline (T0).
Time frame: Approximately 8 weeks after baseline (T1)
Informant-reported Adaptive Functioning - original ABAS-3 scores
The ABAS-3 (Adaptive Behaviour Assessment System - Third Edition) is an observational scale that measures adaptive behaviour. Both self-report and informant report versions are available. In the context of the current study, a 30-item abbreviated version is used. Composite scores are calculated: a total score and three domain scores (conceptual, social and practical domain). Scores range from 0-90 for the total scale and 0-30 for each domain scale. Higher scores indicate better adaptive functioning. For the informant-report an adapted version of the original is used; the adaptations for the self-report version are replicated for the informant version.
Time frame: At baseline (T0)
Informant-reported Adaptive Functioning - adapted ABAS-3 scores

Scores range from 0-90 for the total scale and 0-30 for each domain scale. Higher scores indicate better adaptive functioning. For the informant-report an adapted version of the original is used; the adaptations for the self-report version are replicated for the informant version.

Self-reported Adaptive functioning - SCAF
The SCAF (Screener for Adaptive Functioning) is a screening questionnaire for adaptive functioning for individuals who may have MID or BIF. The SCAF yields a total AF score (min 0 - max 24), with higher scores indicating better adaptive functioning.
Time frame: At baseline (T0)
