Enhancing Description and Interpretation of Qualitative Interviews With People With Intellectual Disabilities Through Nonverbal and Paraverbal Data Collection and Analysis.

The paper says it does not report the findings of the exemplar sleep study, so it is not evidence about sleep problems. Only six participants were included, so the method is described from a small set of interviews. Participants had to be verbal, able to demonstrate abstract thinking and able to use Talking Mats, so the method may not fit people with more severe communication needs. Interpreting nonverbal and paraverbal cues is subjective, and some cues conflicted with speech without a clear explanation. The authors did not analyse verbal data separately without nonverbal data, so it is unclear how much the interpretation changed by including nonverbal cues. Video equipment could affect participant comfort, although participants were given some control over recording.

The funding section states the authors have nothing to report, and the conflicts section states they declare no conflicts of interest.

Do not conclude that video recording and nonverbal transcription improves care or interview accuracy. The paper describes a method and examples from six participants, and it says interpretation of nonverbal communication is subjective and not tested against a verbal-only analysis.
