Borderline Personality Disorder: China

To find the requested statistics surrounding Borderline Personality Disorder (BPD) in China, we carried out extensive and deep-reaching research through various reputable sources such as medical publications from NCBI, as well as scholarly research works from ResearchGate, ScienceDirect and Europe PMC.
Albeit resources that provide statistical results were relatively scarce for China, and the concept of BPD has not been uniformly accepted in China, we have been able to find enough quantitative data to provide 7 statistics surrounding BPD in China. To achieve this, we had to expand our research scope to include resources and studies from later than the last two years. Our findings are presented below.

STATISTICS SURROUNDING BPD IN CHINA

1. In a study published in 2017 and involving 2,709 Chinese female inmates, it was found that BPD had a prevalence rate of 10.26% among Chinese female inmates.
2. In a study published in 2018 and involving 577 male methamphetamine users from two male compulsory detoxification treatment facilities in Hunan province in China, it was found that BPD had a prevalence rate of 20.2% among methamphetamine users in China.

3. A study to investigate the frequency, clinical characteristics, and comorbidity of BPD among psychiatric outpatients in two clinics at the Shanghai Mental Health Center was carried out in 2014. The study involved 3,075 outpatients who were screened using the Personality Diagnostic Questionnaire -IV+. Of these screened outpatients, 2,284 patients who were positive for a personality disorder were assessed using the Structured Clinical Interview for DSM-IV Personality Disorders and it was found that the frequency (prevalence rate) of BPD among the psychiatric outpatients was 5.8%, with a frequency (prevalence rate) of 3.5% among males and 7.5% among females.

4. Xiao et al. in 2006 reported in a study that, 1.3% of outpatients and 1.7% of inpatients at the Shanghai Mental Health Center met the DSM-IV criteria for BPD when they were assessed for dissociative disorders using the Dissociative Disorders Interview Schedule (DDIS).

5. Yang et al. in 2000, after investigating 651 outpatients and 2,023 inpatients who were not randomly sampled, reported that 7.1% of Chinese psychiatric patients met the criteria for BPD when assessed with the Personality Disorder Interview-IV (PDI-IV).

6. In a 2017 cross-cultural study that aimed to identify “cultural factors that may change the presentation, assessment, and response to treatment among adults and adolescents with BPD”, it was cited that in the last decade, BPD studies among the general and psychiatric populations of China had exploded. From the results of some of these studies, it was found that the prevalence of BPD in China ranges from less than 1% to 1.8% in college students, to up to 8.4% in high schools students and 0.3% in factory workers.

7. In a 2017 study that aimed to examine the association among self-compassion, childhood invalidating environment, and BPD symptoms in a sample of Singaporean undergraduate students, 290 undergraduates from the National University of Singapore (NUS) were featured. The featured sample was 72% feminine and 89.7% of the sample were Chinese.
The results from the study showed that there is “a significant positive correlation” between BPD symptomatology and an invalidating childhood experience, with a Pearson’s correlation coefficient of r = 0.27. Also, the results showed that there is “a significant negative correlation” between BPD symptomatology and self-compassion, with a Pearson’s correlation coefficient of r = -0.60.
