How to attune self-report measures for people with cognitive impairments

Recent articles by Havercamp et al. (2020) and Shogren (2021) emphasized the importance of using self-report measures to gain insight in the thoughts and feelings of individuals with Intellectual Disabilities (ID). Proxies can provide useful observations of an individual’s functioning, but they can never directly observe nor fully understand another person’s subjective mental states such as emotional distress, worries or happiness (Lindsay & Skene, 2007).

Clinicians and researchers can use self-report questionnaires or interviews to ask persons about their mental states directly. However, many of these instruments prove to be difficult to understand for individuals with ID. To attune measures to the needs and capabilities of individuals with ID, researchers have proposed many different adaptations and supportive procedures.

With our review, we set out to gather all recommendations from 25 years of peer-reviewed research and appraise the quality of the evidence supporting these recommendations. Not many recommendations proved to be well-researched and the evidence for most was not conclusive. The findings from our review therefore offer preliminary guidance for clinicians and researches who wish to use measures that are ‘ID-inclusive’. Interesting avenues for further scientific exploration are mentioned in the Discussion section.

Target Article

Kooijmans, R., Mercera, G., Langdon, P.E., & Moonen, X. (2022). The adaptation of self-report measures to the needs of people with intellectual disabilities: a systematic review. Clinical Psychology: Science and Practice.  DOI: 10.1037/cps0000058

Discussion Questions

  1. Most recommendations have high degree of ‘practice credibility’, but are not well-researched. Should all recommendations in this review that are mainly described as ‘best practices’ be used to guide developers? Or should we recommend to use only the well-established suggestions?
  2. Not many concrete recommendations are given to assess an individual’s capacity to provide valid and reliable self-reported information. How should we decide if an individual is capable of self-report?
  3. Many references included in the review refer to studies undertaken more than 20 years ago. Should we assume that their results still hold in the current time frame? Or is an update necessary?
