Background The cognitive interview (CI) has been shown to increase correct memory recall of a diverse range of participant types, without an increase in the number of incorrect or confabulated details. However, it has rarely been examined for use with adults with intellectual disability. Measures and Method This study compared the memory recall of twenty‐one adults with a mild intellectual disability (ID) (IQ 70–50) and twenty‐one adults from the general population (GP). Participants viewed a film of a staged distraction theft and were interviewed using either the CI or the structured interview (SI). Results The CI, when compared to the SI, enhanced the correct recall of person, action and conversation (gist) detail for both participant types, without increasing the number of incorrect or confabulated details reported. The ID group reported significantly less correct information than the GP regardless of the interview used. Conclusion The findings suggest that the CI can enable adults with intellectual disability to provide a fuller picture about an experienced event. Implications of this research are discussed.
