The object is to develop a training system of simultaneous walking and cognitive training for improving cognitive function of people with schizophrenia. The training program, called "Simultaneous Walk And Think for Cognitive Health mobile application software"(SWATCH App), is developed by researchers. A randomized controlled trial will be carried out to test the effectiveness of the training system. Ninety participants will be randomly assigned to: simultaneous training of walking and cognitive group, the cognitive training group, and treatment as usual group. The intervention for those groups will lasts for 12 weeks, with a 12 week of followup. The measurements include the cognitive function, physical fitness, and quality of life.
Background: Schizophrenia is one of the severe mental disorders. In addition to psychiatric symptoms, cognitive impairment is a key clinical feature in this population, which significantly negatively influences their functional performance and independence. While the cognitive remediation therapy demonstrates positive results, it often involves specialized and expensive computerized cognitive training system, which limits its application in clinical setting. More evidence is available to support the benefits of exercise training on cognitive functions of schizophrenia. Combination of exercise and cognitive training is a promising program and can improve cognitive functions of the elderly. However, this combined therapy is still limited to schizophrenia. Simultaneous training of walking and cognitive tasks via auditory mobile application is an innovative program for saving cost, time, and manpower. Further study is needed to develop the simultaneous training program and to examine the effectiveness.
Purposes: To examine the effects of the training program on cognitive functions, fitness, functional performance and quality of life.
Methods: A 3-arm, single-blinded, randomized controlled trial is used to recruit 90 participants and then randomly allocated to the simultaneous training group, the cognitive training group, and the treatment as usual group. The first two training groups receive training for 30-40 minutes, 3 times a week for 12 weeks, as well as a follow-up of 12 weeks. All participants will be assessed at baseline, post-test and follow-up assessment. Primary outcome is cognitive function and secondary outcomes are fitness, functional performance, and quality of life.
Contribution: The study can be used as an evidence-based program to improve cognitive functioning of people with schizophrenia. With the development of mobile App and the use of fitness wearable device, the training program enables people with schizophrenia to walk and practice cognitive training simultaneously in a group format. It will help clinical professionals be able to serve the increasing number of people with severe mental illness with less manpower and specialized equipment. The study is also helpful to better understanding the isolated role of aerobic exercise in the dual-task training, and to apply to other groups, like the elderly or dementia.

Cognitive function
MATRICS Consensus Cognitive Battery: Traditional Chinese Version (MCCB) consists of 10 individually administered tests to measure cognitive performance in the following seven domains: 1. Processing Speed 1.1 Trail Making Test (TMT). 1.2 Brief Assessment of Cognition in Schizophrenia: Symbol Coding (BACS SC). 1.3 Category Fluency: Animal Naming (Fluency). 2. Attention 2.1 Continuous Performance Test: Identical Pairs (CPT-IP). 3. Working memory 3.1 Wechsler Memory Scale-III (WMS III): Spatial Span. 3.2 Wechsler Letter: Number Sequencing (WAIS-III). 4. Verbal Learning 4.1 Hopkins Verbal Learning Test-Revised (HVLT-R). 5. Visual Learning 5.1 Brief Visuospatial Memory Test-Revised (BVMT-R). 6. Reasoning and Problem Solving 6.1 Neuropsychological Assessment Battery (NAB): Mazes. 7. Social Cognition 7.1 Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT): Managing Emotions.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Body composition
Using Body Mass Index (BMI) as the measurement of body composition, which weight and height will be combined to report BMI in kg/m\^2.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Cardiorespiratory fitness
Using 6-minute walk test (6MWT) as the measurement, which let the participant walks as far as possible over a total of six minutes on hard and flat floor. And the researcher will measure the distance that participant walks in 6 minutes.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Leg muscular strength and endurance
Using 30-Second Sit to Stand Test. The participant will sit in the middle of the chair, and rise to a full standing position, then sit back down again. Repeat these movements for 30 seconds. And researcher will count the times.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Balance and Agility
The Timed Up and Go test (TUG). It measures the time that the participant takes to rise from a chair, walk eight foots, turn around, walk back to the chair, and sit down.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Dual-Task Performance Involving Hand Dexterity and Cognitive Tasks
Dual-Task Performance Involving Hand Dexterity and Cognitive Tasks, this test is combine the Purdue Pegboard Test (PPT; Tiffin \& Asher, 1948) and the Serial Sevens Subtraction Test (SSST; Manning, 1982), Purdue Pegboard Test use to measures hand dexterity; Serial Sevens Subtraction Test as a cognitive task for the dual-task condition.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Instrumental Activity of Daily Living (IADL)
Lawton and Brody Instrumental Activity of Daily Living Scale is a self-report survey. It is used to evaluate the degree of participant's instrumental activities. There are total 8 descriptions, the scale scores ranges is between 0 to 8. The higher values represent a better outcome.
Time frame: Change from baseline outcome measure at 12th week (post-test), and at 24th week (follow-up test)
Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4)
Schizophrenia Quality of Life Scale Revision 4 is a self-report survey. It is used to evaluate the degree of participant's quality of life. There are total 33 items, the scale scores statements are rated 1 (never) to 5 (always). The higher values represent a better outcome.
