Keep your participants close, but your informants closer? The added value of high and low contact informants to supplement self-report for the cognitive impairment of schizophrenia
Our results suggest that interviewers relied on informant reports significantly more than the participant self-report, even with an informant who spends as little as 2 h a week with a participant. Future research should assess the relationship of informant ratings with cognition or symptom scales.
