"Clinical Global Impression of Improvement (CGI-I), No Change Rating by Visit"

"The CGI-I is a clinician rated instrument that measures change in participant's psychiatric condition (or lack thereof in the stratum without psychiatric disorders) on a 7 point scale ranging from 1 (very much improved) to 7 (very much worse), with 4 = no change. The ratings were applicable even to those without psychiatric diagnoses (eg, those with no psychiatric symptoms would be rated as normal, not at all ill on the CGI-S at baseline and assuming no psychiatric symptoms emerge during the trial, would be rated as no change on the CGI-I at follow-up visits). For those participants with a psychiatric diagnosis, the clinician should rate the severity of the mental illness with respect to the clinician's experience with the psychiatric population to which the participant belongs."

Detectibility (d') of Continuous Performance Test

The value d' is a measure of the difference between the signal (non-X) and noise (X) distributions. As such, d' provides a means for assessing an individual's discriminative power since, in general, the greater the difference between the signal and noise distributions, the better the ability to distinguish and detect X and non-X stimuli. The lower the score, the better the detectability. Values shown below are for week 12. (NCT01111149)
Timeframe: Week 12

Response Style Indicator (Beta) for CPT

Beta represents an individual's response tendency: Some individuals are cautious and choose not to respond very often. Conceptually, such individuals want to make sure they are correct when they give a response. Higher values of Beta reflect this response style. The emphasis is on avoiding commission errors. Other individuals respond more freely to make sure they respond to most or all targets, and they tend to be less concerned about mistakenly responding to a non-target. Lower values of Beta are produced by this response style. Values shown below were obtained at week 12. (NCT01111149)
Timeframe: Week 12

Variability of Standard Error - CPT

"Variability of Standard Error (VSE) is a measure of response speed consistency. VSE measures within respondent variability. That is, the amount of variability the individual shows in 18 separate segments of the Continuous Performance Test in relation to his or her own overall standard error. Although VSE is a different measure than Overall Standard Error, typically the two measures produce comparable results. The higher the VSE, the greater the inconsistency in the response speed. The values shown below are the VSE for Week 12." (NCT01111149)

Abnormal Movements - AIMS

Abnormal Involuntary Movement Scale (AIMS), to assess abnormal involuntary movements associated with antipsychotic drugs. There are 10 questions, based on a five-point scale ranging from 0 (none) to 4 (severe). Items 11-14 are yes/no questions that have no impact on the score. The Total Score is the sum of questions 1-7 (minimum = 0; maximum = 28). The severity index consists of one question (item 8; rated 0=none to 4=severe) based on the rater's observation of abnormal movements The AIMS Global Score is the sum of three questions (each item rated 0=none to 4=severe) regarding abnormal movements overall (minimum score 0, maximum score 12). For the total score and subscores, the higher the score, the greater the severity of abnormal movements. Scoring is based on the chapter: Guy W (2000), Abnormal Involuntary Movement Scale (AIMS), in: Handbook of Psychiatric Measures (Rush AJ Jr, et al., eds). APA Publishing: Washington DC: pp. 166-167.

Hit Reaction Time - CPT

The hit reaction time is the average speed of correct responses for the entire test given in milliseconds. The higher the score, the slower the speed. The standard error is a measure of response speed consistency. The higher the overall standard error, the greater inconsistency in the response speed. The values below were measured at week 12. (NCT01111149)
Timeframe: Week 12

Impulsivity and Inattention

Impulsivity and inattention will be measured using the continuous performance test. Individuals were tasked with 359 items divided six blocks (59 in block 1, 60 in blocks 2-6). Omissions result from the failure to respond to target letters. CPT% Omissions measures the percentage of responses that qualify as omissions made during the test. Higher scores indicate increased inattention. Commissions result from responses given to non-targets. CPT% Commissions measures the percentage of responses that qualify as commissions made during the test. Higher scores indicate increased inattention. Perseverations result from reaction time less than 100 ms. CPT% Perseveration % measures the percentage of responses that qualify as perseverations made during the test. The higher the score, the greater impulsivity. (NCT01111149)
