Interrater Reliability and Coding Guide for Nonpsychotic Formal Thought Disorder

Reliable and valid assessment of abnormal speech patterns may enable
earlier recognition of nonpsychotic disorders through characteristic speech
patterns. This study sought to establish interrater reliability using a standardized guide
for scoring. A scoring guide defining 27 elements (e.g., inappropriate self-reference,
simple loss of goal, circumstantiality) of disordered thought was developed. The seminal
work of Andreasen's and Holzman's groups provided 12 elements, and 15 new elements
were suggested by clinical literature. Audiotaped interviews with 12 psychiatric
inpatients, adults of both sexes and various ages hospitalized for acute management of
nonpsychotic psychiatric disorders, provided speech samples for observation of disordered
thought by two independent raters. Using the guide's definitions and accompanying
examples of elements of disordered thought, reliability in scoring was high
(kappa of .85 for agreement on the presence of any abnormal speech element and
kappa values from .66 to 1.00 for agreement on the presence of individual elements).
