Psychometric Properties of the Questionnaire Epistemic Trust in People With Mild to Moderate Intellectual Disabilities or Borderline Intellectual Functioning.

Background: To assess epistemic trust in people with intellectual disabilities, we adapted the Questionnaire Epistemic Trust (QET) for people with mild to moderate intellectual disabilities or borderline intellectual functioning (MMID/BIF).

Method: We investigated the factor structure, the reliability and construct validity in 147 adults.

Results: We replicated the 4-factor structure, after excluding four items with low factor loadings.

Scale of Emotional Development-Questionnaire: A Systematic Approach to Improving Performance.

Background: In people with intellectual disabilities, emotional development progresses more slowly or stagnates, which can result in challenging behaviours. The Scale of Emotional Development-Questionnaire was designed to chart people's own emotional development, providing insight into basic emotional needs and resilience, while reducing prejudice, enhancing self-awareness and improving emotional expression.

Methods: The questionnaire was completed by 134 participants with moderate to borderline intellectual disabilities.

Supporting young siblings of children with intellectual disabilities and/or visual impairments with the serious game 'Broodles': A mixed methods randomized controlled trial.

Background: Siblings of children with neurodevelopmental conditions experience conflicting emotions and have an increased risk of mental health problems. Several sibling interventions have been developed, but few are readily available, leaving many siblings unsupported. Therefore, the free, online, self-administered sibling serious game 'Broodles' was developed.

Cultural applicability and desirability of 'Broodles': The first serious game intervention for siblings of children with disabilities.

Objective: Serious games can serve as easily accessible interventions to support siblings of children with disabilities, who are at risk of developing mental health problems. The Dutch serious game 'Broodles' was developed for siblings aged 6-9 years. The current study aims to assess the cultural applicability, desirability, feasibility, and acceptability of 'Broodles' in Norway.

Effectiveness of the mentalisation-based serious game 'You & I' for adults with mild to borderline intellectual disabilities: A randomised controlled trial.

Background: Mentalising and stress regulation pose challenges for adults with mild to borderline intellectual disabilities (MBID), emphasising the importance of an intervention program. The study examined the effectiveness and social validity of the serious game 'You & I' in enhancing mentalising and stress regulation among adults with MBID.

Method: A randomised controlled superiority trial with experimental and waitlist-control groups was conducted with 159 adults with MBID (M  = 36) at baseline, post-test, and follow-up.

Lessons learned from the adaptation of the Reflective Functioning Questionnaire (RFQ) for Dutch people with mild to borderline intellectual disabilities.

Background: People with mild to borderline intellectual disabilities (MBIDs) face challenges in social functioning, possibly as a result of limited mentalising abilities such as reflecting on the behaviour of themselves and others. Reflective functioning in people with MBIDs has not yet been investigated due to a lack of instruments. The Reflective Functioning Questionnaire (RFQ) is a seemingly easy adaptable, short self-report questionnaire.

The effectiveness of the serious game "Broodles" for siblings of children with intellectual disabilities and/or visual impairment: study protocol for a randomized controlled trial.

Background: Siblings of children with disabilities also need support. However, there are only a few evidence-based interventions for these siblings. The current study aims to assess the effectiveness of a newly developed serious game for young siblings of children with intellectual disability (ID) and/or visual impairment (VI).
