The purpose of the study is to examine the effect of auricular acupressure on improvement of constipation and heart rate variability among residents with schizophrenia in community rehabilitation Center.The hypothesis of this study is that residents with schizophrenia in Community Rehabilitation Center receiving auricular acupressure can improve the symptoms of constipation and heart rate variability.By identifying the effectiveness of auricular acupressure can reduce the occurrence of constipation; suitable care can be suggested to improve gastrointestinal health in residents of Schizophrenia in community rehabilitation center.

Subjective defecation condition is related to self-perceived constipation measured by the Patient Assessment of Constipation Symptoms scale. Objective defecation condition includes frequency of defecation, the grade of Bristol Stool Scale and heart rate variability. Mean, standard deviation, frequency, percentage, t-test and chi-square test will be used to analyze the data.
