February 19, 2020 updated by: Yi Li MD, PhD, Huazhong University of Science and Technology
The Effect of Long-acting Antipsychotic on Schizophrenia Patients With Violence Risk : a Observational Cohort Study
This is a 49 weeks prospective, non-interventional cohort study.
To observe the effect of long-acting injection antipsychotic(LAI), paliperidone palmitate on prevention of recurrence and symptom control in schizophrenia patients with violence risk.
This study can be extended according to the implementation of the project and extended follow-up time.
Study Overview
Detailed Description
This is a 49 weeks prospective, observational cohort study.

This observational study will build the cohort of schizophrenia patient with violence risk and treated with LAI paliperidone palmitate.
The effect of long-acting antipsychotic, paliperidone palmitate, will be observed on prevention of recurrence and symptom control in these patients.
safety information and laboratory tests result will also be collected.
This study can be extended according to the implementation of the project and extended follow-up time.

The scale takes four functional dimensions into account: a) social useful activities, including work and study, b) the relationship between the individual and society, c) self-care, and d) disturbing and aggression

The IRI was designed to assess empathy.It contains 4 sub-scales, each with 7 items.
It uses a 5-item Likert scale with two anchors (A = Does not describe me well; E= Describes me very well).
Responses can be averaged (using 0 to 4 or 1 to 5 endpoints) or summed (using 0 to 28 or 7 to 35 ranges).
The IRI is a continuous measure of empathy in normal populations and not a categorical ,measure ("high empathy" versus "low empathy").

Facial Emotion Recognition scale
Time Frame: 49 weeks
|
Computer-morphed images derived from the facial features of real individuals, each showing a specific emotion, are displayed on the screen, one at a time.
Each face is displayed for 200ms and then immediately covered up to prevent residual processing of the image.
The participant must select which emotion the face displayed from 6 options (sadness, happiness, fear, anger, disgust or surprise).
The outcome measures for ERT cover percentages and numbers correct or incorrect and overall response latencies, which can be looked at either across individual emotions or across all emotions at once.

Toronto Alexithymia Scale(TAS)
Time Frame: 49 weeks
|
Toronto Alexithymia Scale, the TAS is a 20-item instrument that commonly used measures of alexithymia.
It is a self-report scale that is comprised of 20 items.
Items are rated using a 5-point Likert scale whereby 1 = strongly disagree and 5 = strongly agree.
There are 5 items that are negatively keyed (items 4, 5, 10, 18 and 19).
The total alexithymia score is the sum of responses to all 20 items, while the score for each subscale factor is the sum of the responses to that subscale.
The TAS-20 uses cutoff scoring: equal to or less than 51 = non-alexithymia, equal to or greater than 61 = alexithymia.
Scores of 52 to 60 = possible alexithymia.
