In asking questions:

• Break down complex questions into several simple questions and ask them one at a time.
• Ask open-ended and free recall questions instead of "yes/no" questions (e.g. "What did you see?" instead of "Did you see the man break the window pane?")
• Ask the person if he/she wants the question to be repeated if no reply is forthcoming.
• Repeat the question or phrase it in a different way if you suspect that the person may not have understood it (asking the question repeatedly is better than interpreting the response inaccurately).
• Use points of reference when asking for information regarding time and sequence of events, and use landmarks when asking about locations.
• When in doubt, try asking the same question in a different way to confirm earlier responses (or seek validation from a different source).
• Use words of encouragement and, if the interview is not progressing very well, ask if the person needs a break.

• Bear in mind that it is possible that a person with intellectual disabilities may agree with something even if it's not the truth because he/she:

  (1) feels that is what the interviewer wants to hear
  (2) wants to hide his/her inability to read/understand/recall
  (3) feels that such an answer would not require further elaboration
  (4) believes that the interviewer can be trusted and knows best
  (5) doesn't want to appear "stupid"

• Some persons may require the help of a support person or advocate when communicating, while others may require different communication aids like communication boards or pictures. ³⁴
