Table 3.

Percentage of total sample characterized by types of thought disorder subsumed under the disconnected subtype

Absent (%) Mild (%) Moderate (%) Severe (%) Extreme (%)
Tangentiality 46.70 16.40 20.60 12.70 3.60
Derailment 54.50 15.20 17.60 9.70 3.00
Incoherence 80.00 8.50 8.50 1.20 1.80
Circumstantiality 66.70 20.00 11.50 1.80 N/A
Loss of Goal 58.20 20.60 17.00 4.20 N/A

Note: Absent = No instances over whole interview; Mild = occurs once or occasionally; Moderate = two to four times; Severe = 5 to 10 times or in the case of circumstantiality, many such that this pattern of responding continues despite being interrupted by examiner; Extreme = more than 10 times, interview is largely incomprehensible).
