The Children's Interrogative Suggestibility Scale

Vicki L. McCloskey (1997)

This paper describes the construction of the Children's Interrogative Suggestibility Scale (CISS), its theoretical foundation, validation data, and possible research and clinical uses. The scale is the only objective tool available for the assessment of interrogative suggestibility in children. It provides a quick and systematic method for the measurement of suggestibility. It consists of two factors, Yield and Shift, whereby Yield is a measure of the extent to which a child "yields" to leading questions and Shift measures the extent to which a child will "shift" his/her responses after the application of interpersonal pressure in the form of negative feedback. The scale contains 13 items in each of the two parts and has satisfactory internal-consistency reliability. The paper presents norming data for children ages 4 to 7. Findings presented indicate a significant relationship among memory, age and suggestibility with older children having better memory and less suggestibility.
