GAF is a 100-point tool rating overall psychological, social and occupational functioning of adults. The higher score range (91-100) refers to a superior functioning in a wide range of activities, and absence of symptoms. The lower score range (1-10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death. Lower scores indicate worsening.

The WHOQOL-BREF is a 26-item, self-report questionnaire and short version of WHOQOL-100, consisting of 4 domains: physical health (7 items), psychological health (6 items), social relationships (3 items), and environmental health (8 items); it also contains QOL and general health items. Domain scores are scaled in a positive direction (i.e. higher scores denote higher quality of life). The mean score of items within each domain is used to calculate the domain score. Each individual item of the WHOQOL-BREF is scored from 1=not at all to 5=completely on a response scale, which is stipulated as a 5-point ordinal scale. The scores are then transformed linearly to a scale of 0 (the worse quality of life) to 100 (the worse quality of life).

The K-WAIS is a Korean version of the Wechsler Adult Intelligence Scale-Revised (WAIS-R). It is an intelligence test that assess 3 general areas of intelligence quotients (IQ): verbal IQ, performance IQ and full-scale IQ (FSIQ). The verbal IQ includes: Digit Span, Vocabulary, and Arithmetic; performance IQ includes: Picture Arrangement and Block Design; and FSIQ is an IQ assessed by measuring an individual's overall level of general cognitive and intellectual functioning. The highest FSIQ is 160. The greater the quotient, higher the level of intelligence.

The Controlled Oral Word Associated Test is a measure of verbal fluency, which requires participants to generate words orally that begin with a given letter of the alphabet. Participants are given 1 min to name as many words as possible. Performance was calculated by the number of words generated in the 1-min period. This measure, requiring rapid and organized word retrieval, is a sensitive indicator of brain dysfunction.

The KAVLT is a neuropsychological assessment designed to evaluate verbal memory in participants. The KAVLT is useful in evaluating the nature and severity of memory dysfunction and to track changes in memory function over time. The test is designed as a list-learning paradigm in which the participants hears a list of 15 words, and are asked to recall as many words from the list as possible. This procedure is carried out a total of 5 times. Then a second list of 15 words is presented, allowing the participants only 1 attempt to recall. Immediately following this, the participants are asked to remember as many words as possible from the first list. KAVLT consists of 2 test conditions: Delayed Recall and Delayed Recognition. The upper limit for 'words recalled' is 15, which represents better episodic memory.

The RCFT is a neuropsychological assessment designed to evaluate visual memory in participants. The RCFT is useful in evaluating the spatial perception and visual memory. The RCFT consists of 3 test conditions: Copy, Immediate Recall and Delayed Recall. At the first step, participants are given the RCFT stimulus card, and then asked to draw the same figure. Subsequently, they are instructed to draw what they remembered. Then, after a delay of 30 min, they are required to draw the same figure once again, a score of 2 points for each drawn element (a complete straight line or a circle) remembered correctly. The total score is the sum of points scored for each correctly drawn element and it ranges from 0 to 36. The maximum score indicates excellent visual memory.

MQ was obtained by adding up the results of verbal memory and visual memory test. The memory quotient will include learning curve, memory retention, retrieval efficiency, drawing/memory consistency, verbal/visual memory consistency and intelligence/memory consistency. The highest MQ is 160, which indicates excellent memory.

TMT is attention, mental flexibility, visual search, motor function measure test. Test is divided into A and B types. Participants using a pencil or connect numbers in sequence (A-type), in turn, alternating between numbers and letters must be connected (B-type). The test measures the response time.

The LUNSERS is a self-report measure of antipsychotic side effects. It consists of 51 questions, 41 questions on side effects and 10 questions are of "red herrings" to validate the results. Each question is rated on a 4-point scale, where 0=not at all; and 4=very much. The total neuroleptic side effect score is the sum of the scores for the side effects items (i.e. all items excluding the red herrings). Total side effects score ranges from 0 to 164, where 0 to 40=low side effect rating, 41 to 80=medium side effect rating and greater than 81=high side effect rating.

The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of medication and 2) attitudes and beliefs toward neuroleptics which may influence medication compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score for each person at each time is the positive score minus the negative score.

A scale used to assess the extrapyramidal symptoms attributable to antipsychotics. It consists of 9 items (8 to assess individual symptoms and 1 to assess global severity). Each item is assessed from 0 (none, normal) to 4 (severe). The total score is the sum of the 8 item scores, for a total range of 0 (normal) to 32 (severe). The items for the assessment of individual symptoms are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia.

The CGI-S rating scale is used to rate the severity of a participant's psychotic condition on a 7-point scale. It is rated as follows: 1=Normal, not at all ill, 2=Borderline mentally ill, 3=Mildly ill, 4=Moderately ill, 5=Markedly ill, 6=Severely ill, and 7=Among the most extremely ill. Higher scores indicate worsening.
