The purpose of this study is to clarify the Qi-blood-fluid patterns of psychiatric disorders such as depression,
anxiety disorders, eating disorders, somatoform disorders and psychosomatic disorders such as irritable bowel
syndrome, functional dyspepsia, etc. according to oriental medicine. The subjects were all new cases who con-
sulted the psychosomatic clinic of Kyushu University Hospital from June 2000 to March 2001. Qi-deficiency,
Qi-stagnation, Qi-flowback, blood deficiency, and fluid retention scores were calculated from the chief com-
plaints and answers to the 102 questions of the Kyudai Medical Index (KMI), according to Terasawa’s
Qi-blood-fluid scoring system. Since the results of physical examinations were not investigated, items requiring
physical examination in Terasawa’s criteria were excluded from the calculation. The Qi-flowback, blood defi-
ciency and fluid retention scores were significantly higher in females than males. Strong correlations were ob-
served between Qi-deficiency and Qi-stagnation in males and between blood deficiency and fluid retention in
both sexes. Multiple logistic regression analysis revealed that Qi-deficiency and Qi-stagnation in both sexes, es-
pecially Qi-deficiency, in males, were associated with major depression. Qi-flowback in females only and blood
deficiency in males only were associated with anxiety disorders or a high State-trait Anxiety Inventory score. In
females, Qi-flowback was also associated with somatoform disorders and irritable bowel syndrome. These re-
sults may be of assistance in treating occidental diseases in an oriental manner.

Introduction
When occidental medicine is ineffective for psychosomatic
or psychiatric diseases, classification of the diseases according
to the oriental concepts might be helpful for proper treatment.
There have been many reports in which depressive state cases
were attributed to visceral patterns such as spleen deficiency
(Wang, Wang, Qiao, & Li, 2009; Yuasa, 1999), liver blood de-
ficiency (Yang & Zhi, 1994), lung deficiency (Yuasa, 1999) and
heart deficiency (Chan, Briscomb, Waterhouse, & Cannaby,
2002). Apart from visceral patterns, the concept of Qi-blood-
fluid patterns is also helpful, since there are many specific Chi-
nese herbal extract preparations corresponding to specific com-
bination of a few Qi-blood-fluid patterns. Qi represents vital
energy, which is necessary for organ functions, production of
kidney yang, and immune function. Qi abnormalities are di-
vided into Qi-deficiency, Qi-stagnation, and Qi-flowback (K.
Terasawa, 2004). Qi-deficiency is congenital or attributed to
anorexia or excessive fatigue. Qi-stagnation results from im-
paired intra- and extra-channel circulation of Qi. Qi-flowback is
an adverse current of efferent or downward current of Qi. Rep-
resentative blood patterns are blood deficiency resulting from
reduced production or excessive consumption of blood, and
blood stagnation resulting from cold, traumatic circulatory fail-
ure, or stasis (K. Terasawa, 2004).
There have been no reports in which the extents of
Qi-blood-fluid patterns were calculated in patients with psychi-
atric or psychosomatic disorders. However, there have been
some reports that depression or some anxiety disorder was
treated with herbal extract preparations associated with Qi-
blood-fluid patterns. Thus, it was hypothesized that associations
between some single Qi-blood-fluid pattern or some character-
istic combination of Qi-blood-fluid patterns and each psychiat-
ric or psychosomatic disorders such as depression, anxiety dis-
orders etc. would be revealed by quantifying the extent of
Qi-blood-fluid patterns of all the subjects. In order to quantify
the extent of Qi-blood-fluid patterns, a scoring system (Appen-
dix 1) was developed by Tera- sawa et al. (Katsutoshi Terasawa,
C. ENGLERT ET AL.
644
1990; K. Terasawa, 2004). For example, the diagnostic criterion,
Qi-deficiency score, was devised as follows. First, the author
Terasawa synthetically observed subjective symptoms and ob-
jective findings of the patients. The severity of Qi-deficiency,
assessed by the observation was graded to four levels by the
author’s empirical knowledge. The grade was set as “overall
scale”. Second, the prevalence of the symptoms and signs re-
ported to be related to Qi-deficiency in the previous studies was
ordered to four levels. The attributable proportion of prevalence
for each symptom or sign to the overall scale was estimated by
the multiple regression analysis, and accordingly constituted as
Qi-deficiency score. In addition, Qi-stagnation, Qi-flowback,
blood deficiency, blood stagnation, and fluid retention scores
are calculated according to this system.
Although this scoring system was not subject to indefectible
validation by a third person, it is the first and the only approach
to quantify Qi-blood-fluid patterns. Thus, we considered it
would be useful to calculate the extent of Qi-blood-fluid pat-
terns of all the subjects and investigated the association be-
tween the extent of Qi-blood-fluid patterns and the major rep-
resentative diseases at a psychosomatic clinic, including de-
pression, anxiety disorder, eating disorder, and somatoform
disorder according to Diagnostic and Statistical Manual of
Mental Disorders 4th Edition (DSM-IV). In the present study,
the Qi-blood-fluid pattern scores were calculated based on the
chief complaints and answers to questionnaires according to
Terasawa’s Qi-blood-fluid scoring system for each patient who
consulted the psychosomatic clinic at the tertiary medical care
center. The associations between the Qi-blood-fluid patterns
and indices of depressive state, i.e., Self-rating Depression
Scale (SDS) (Zung, Richards, & Short, 1965) scores, or indices
of anxiety state, i.e., State-trait Anxiety Inventory (STAI)
scores were also investigated.
Materials and Methods
Subjects
The subjects of this study were outpatients who visited for
the first time during the period from June 2000 to March 2001
the clinic of the Department of Psychosomatic Medicine in
Kyushu University Hospital, a tertiary medical care center. This
department provides western psychosomatic and psychiatric
medicine. Approximately half of them were walk-in patients
and the others were referrals. After preexamination by the phy-
sician in order to make a provisional diagnosis, the patients
were assigned to the attending physicians and given a complete
checkup. Subjects with organic neurological disorders, endo-
crine disorders, neoplasm, vascular disorders, infection, degen-
erative diseases, or traumatism were excluded from the analy-
ses. Subjects whose diagnoses could not be identified, whose
chief complaints were not described, or who left more than 21
questions on the KMI questionnaire unanswered, were also
excluded. Thus, 579 subjects remained among all the 914 out-
patients. All of the 579 participant patients gave written in-
formed consent for the relevant medical examinations. The
protocol of the present survey was approved by the Research
Ethics Committee of Graduate School of Medical Sciences,
Kyushu University.
Assessment of Symptoms
At the preliminary examination, questionnaires and an inter-
view were conducted with each outpatient, who gave written
consent. All the patients were asked to describe up to three
chief complaints. The questionnaires included the Kyudai
Medical Index (KMI), a modification of the Cornell Medical
Index-Health Questionnaire (Matsuoka, 1990), SDS, and STAI.
Subjective psychiatric symptoms associated with depressive
disorders were assessed by the SDS questionnaire. The state
anxiety and trait anxiety were assessed by STAI-I and STAI-II,
respectively, which were parts of STAI (Spielberger, Gorsuch,
& Lushene, 1970). The reliability and validity of the SDS for
testing depressive state have been proven (Zung et al., 1965).
The cutoff score for screening depression has been reported to
40 points (Zung et al., 1965). The reliability and validity of
Japanese version of STAI for testing anxiety has been proven,
whose Cronbach’s coefficient alpha was as much as 0.92 (Na-
kasato, 1990). The KMI consists of 102 yes or no questions,
which include two comprehensive questions, two questions
about past history, two questions about family history, 50 ques-
tions about psychiatric symptoms, and 46 questions about so-
matic symptoms. It has been reported that Category B and C
scores in KMI could distinguish healthy controls from patients
with psychosomatic disorders and those with neurotic disorders.
It could also distinguish patients with neurotic disorders from
those with psychosomatic disorders (Matsuoka, 1990).
Evaluation o f Symp t oms and Signs in Oriental
Syndromes
The oriental syndromes derived from Qi, blood or fluid in
each patient were evaluated according to Terasawa’s Qi-blood-
fluid scoring system for the diagnosis of Qi-deficiency, Qi-
stagnation, Qi-flowback, blood stagnation, blood deficiency,
and fluid retention (Katsutoshi Terasawa, 1990; K. Terasawa,
2004). For example, the B-42 question in the KMI, “Do you
enjoy nothing and are you depressed?” was regarded as a de-
pressive mood, which corresponds to 18 points for Qi-stagna-
tion in Terasawa’s system. As a whole, 8 of 14 factors in Qi-
deficiency criteria, 11 of 12 factors in Qi-stagnation criteria, 11
of 12 factors in Qi-flowback criteria, 8 of 12 factors in blood
deficiency criteria, and 11 of 18 factors in the fluid retention
criteria corresponded to some of the chief complaints or ques-
tions in the KMI of all the subjects. However, among 17 blood
stagnation factors, only one corresponded to any of the chief
complaints or KMI questions. Therefore, blood stagnation
scores were not calculated. Among the 102 questions of the
KMI, 40 corresponded to factors of Terasawa’s scoring system.
The kinds of chief complaints reached 183. Among them, 58
were included in Terasawa’s scoring system. The correspon-
dence between symptoms described as chief complaints or in
the KMI, and terms related to Qi-blood-fluid patterns are shown
in Appendix 2 and 3, respectively. Some symptoms were in-
quired about twice using different words. Some symptoms cor-
responded to two Qi-blood-fluid patterns. In Terasawa’s scoring
system, a full point count is given when the symptom or sign is
apparent and half the points are scored when it is slight. There-
fore, full scores were assigned to the chief complaints corre-
sponding to Terasawa’s criteria, while symptoms which were
not described as the chief complaints but described in the KMI
questionnaire were regarded to be slight and half scores were
assigned to them.
Statistics
All analyses were performed using Stata version 10.1 (Stata
Corp., College Station, Texas, USA). Kolmogorov Smirnov’s
statistic was calculated to evaluate the normality of the distribu-
tion. Sexual differences in the proportion of diagnoses were
tested by the chi-square test for independence. In order to com-
C. ENGLERT ET AL. 645
pare the means of continuous variables of the two groups,
Welch’s t test was used.
Multiple logistic regression analyses were performed to es-
timate the association between the prevalence of occidental
diagnoses and Qi-deficiency, Qi-stagnation, Qi-flowback, blood
deficiency, and fluid retention, as dummy variables for the
nearest quartiles, adjusted for age (<40 or 40+ years old). To
obtain the correlation between two continuous variables, Spear-
man’s rank correlation coefficients were estimated. A two-sided
p < 0.05 was considered to be statistically significant.
Results
Demographic and Occidental Status
The demographic and occidental aspects of the subjects are
shown in Table 1. The continuous variables are shown as mean
± standard deviation. The mean age of the subjects was 36.4
years old without significant sexual difference.
The average scores in SDS, STAI-I and STAI II were 50.6
points, 54.8 points and 55.3 points per 80 points, respectively.
In KMI, the average score for category B questions, i.e.,
questions assessing psychiatric symptoms, were 23.3 points per
50 points. The average score for the somatic symptoms catego-
rized as KMI C questions was 15.4 per 47 points. These are
close to those of patients with neurotic disorders in the previous
study (Matsuoka, 1990).
The numbers of patients with each disorder and their per-
centage are shown. The prevalence of mood disorders, anxiety
disorders, eating disorders, somatoform disorders, and irritable
bowel syndrome was 54.2%, 19.9%, 10.9%, 7.6%, and 6.6%,
respectively. The total numbers of patients with subclassifica-
tion diseases did not equal the number in each corresponding
major division due to overlapping.
Oriental Status
In order to investigate the extent of Qi-blood-fluid patterns
according to sex and age, analysis of covariance was performed.
As shown in Table 2, Qi-flowback, blood deficiency and fluid
retention were significantly higher in females. Age was nega-
tively correlated with fluid retention scores.
Corr elations among Qi-Blood-Fluid Patterns
(Figure 1)
Since Kolmogorov Smirnov’s value showed skewed distribu-
tion of the fluid retention scores, Spearman’s rank correlation
coefficients were calculated among Qi-blood-fluid patterns by
sex. Strong correlation coefficients (>0.5) were observed be-
tween Qi-deficiency and Qi-stagnation in males and between
blood deficiency and fluid retention in each sex. In females, the
association between the scores was weak on the whole except
for a strong association between blood deficiency and fluid
retention. Relatively strong associations were observed among
Qi-flowback, blood deficiency and fluid retention, between
Qi-deficiency and Qi-stagnation, and between Qi-stagnation
and Qi-flowback in females.
Associations between Qi-Blood-Fluid Patterns and
Occidental Diagnoses
To investigate the association between oriental diagnoses as
given above and occidental diagnoses according to major divi-
sions as given by the attending physicians, multiple logistic
regression analyses were conducted by sex. The adjusted odds
ratio (OR) and its 95% confidence interval (CI) are shown in
Table 3. In the same way, the association between oriental di-
agnoses according to minor divisions was also investigated and
shown in Table 4. Although not shown in the tables, the catego-
rizing age had almost no effect on the results.
Higher Qi-deficiency and Qi-stagnation were significantly
associated with mood disorders and major depression in both
sexes. On the other hand, Qi-deficiency scores were inversely
associated with “depressive disorder not otherwise specified” in
both sexes. The association between dysthymic disorder and the
Qi-blood-fluid patterns was not statistically significant, whose
data are not shown.
In anxiety disorders, the results were different between fe-
males and males. In females, Qi-flowback was associated with
all anxiety disorders as shown in Table 3 and generalized anxi-
ety disorder as shown in Table 4. In males, only blood defi-
ciency was associated with generalized anxiety disorder as
shown in Table 4.
Furthermore, fluid retention in females was associated with
eating disorders as shown in Table 3. Qi-flowback and blood
deficiency in females were associated with somatoform disor-
ders. On the other hand, fluid retention in females was inversely
associated with somatoform disorders.
Associations between somatic diseases and Qi-blood-fluid
patterns were also investigated. As the only positive result,
extremely high Qi-flowback in females was associated with
irritable bowel syndrome, as shown in Table 4.
Associations between Qi-Blood-Fluid Patterns and
Psychological Questionnaire scores (Table 5)
In order to investigate the oriental aspect of psychological
defects, multiple logistic regression analysis was performed.
The dependent variable was SDS, State or Trait anxiety scores.
The explanatory variables were Qi-deficiency, Qi-stagnation,
Qi-flowback, blood deficiency, and fluid retention.
In STAI scores, the results were different between females
and males. In females, any Qi-pattern was associated with ei-
ther high State or Trait anxiety scores. On the other hand, only
high Qi-deficiency among the Qi-patterns was associated with
high STAI scores in males. Instead, blood deficiency was asso-
ciated with high State anxiety scores in males.
All the Qi-patterns in both sexes except for Qi-flowback in
males and blood deficiency in males were associated with high
SDS scores.
Discussion
The average score for psychiatric symptoms categorized as
KMI B questions in the KMI was 23.3/50, which was higher
than the average reported previously for normal subjects, 9.5/50,
and those with psychosomatic diseases, 18.8/50. However, it
was lower than that of patients with neurosis, 24.4/50 (Matsu-
oka, 1990). The average score for the somatic symptoms cate-
gorized as KMI C questions was 15.4/47, which was higher
than that of normal subjects, 5.1/47, that of patients with psy-
chosomatic diseases, 14.8/47, and lower than that of neurosis,
15.6/47, in the previous report (Matsuoka, 1990). Thus, the
subjects of the present study were considered to range between
psychosomatic and neurotic.
The present study indicates that blood deficiency and fluid
retention scores were higher in females than males. The corre-
lation coefficients were more than 0.5 between Qi-deficiency

and Qi-stagnation in males and between blood deficiency and
fluid retention in both sexes. Qi-patterns, especially Qi-defi-
ciency and Qi-stagnation in both sexes and blood deficiency in
males were associated with either major depression or high
SDS scores. Qi-deficiency in both sexes, Qi-flowback in fe-
males, and blood deficiency in males, were associated with
anxiety disorders or high STAI scores. Qi-stagnation in females
was associated with STAI-I and inversely associated with total
anxiety disorders. Fluid retention was associated with eating
disorder in females. Qi-flowback and blood deficiency in fe-
males were associated with somatoform disorders. Qi-flowback
in females was associated with irritable bowel syndrome.
Depression has been considered attributable to Qi-stagnation
(Qiao et al., 2007; Wang et al., 2009; Yu et al., 2007; Zhou et al.,
2006) and it is the case in the present study. However, our study
indicated a stronger association between Qi-deficiency and
major depression than Qi-stagnation in males. This result coin-
cides with the stronger association between Qi-deficiency
scores and SDS scores than between Qi-stagnation and SDS
scores in males. Thus, resupply of Qi is important in treating
male patients in the depressive state. The association with
whole mood disorders was similar to that with major depression,
since major depression made up 75% of the whole mood disor-
ders.
There have been few reports on oriental conditions in pa-
tients with depression. Yang et al. gave acupuncture to patients
with depression in view of their Qi-stagnation, blood stagnation,
and Yan-deficiency, which is a combination of Qi-deficiency
and cold constitution (Yang & Zhi, 1994). Qi-stagnation is re-
portedly associated with depression in more than half of the
cases (Zhou, Chen, & Mei, 2006). In the present study, strong
(more than 0.4) correlations with the SDS score, which reflect
the extent of the psychological aspect of the depressive state,
were observed in not only Qi-stagnation but also Qi-deficiency
and Qi-flowback scores in both sexes. In treating the depressive
state, re-supply of Qi or reducing Qi-flowback would also be
effective as well as disobliteration of Qi-stagnation.
In the present study, examination of the association between
depression and the chief complaints and KMI suggested that the
strong association between depression and Qi-deficiency shown
in Table 3 may be attributed to the strong association between
depression and appetite loss, sensitivity to noise, hypobulia, and
general fatigue among criteria for Qi-deficiency. The strong
association between depression and Qi-stagnation could be
attributed to the strong association between depression and
hypobulia, appetite loss, headache/head discomfort, melancholy,
unpleasant sensation of laryngopharynx, chest oppression, epi-
gastric discomfort, a diversity of symptoms, and dependency of
symptoms on mood.
The strong association between SDS scores and Qi-flowback
is considered attributable to the strong association between
depression and glow/chills, nausea/vomiting, headache, palpita-
tion, sensitivity to noise, feeling of cold, diaphoresis, and
abrupt perspiration, which are Qi-flowback symptoms. These
symptoms also exist in the criteria for panic disorder, which
often coexists with major depression. Recently, the coexistence
and similarity between depression and panic disorder have been
reported, which is an entity called “anxious depression in panic
disorder.” Although no association between panic disorder and
Qi-flowback was detected in the present study, such comorbid-
ity may account for the association between SDS scores and
Qi-flowback. Since Qi-flowback was associated with not only
SDS scores but also STAI scores, anxiety disorders and gener-
alized anxiety disorder in females, depression, and panic disor-
der might share such common pathological mechanisms as to
be explained as Qi-flowback.
Qi-flowback in females was associated with high STAI
scores, anxiety disorders, and generalized anxiety disorder.
This result is considered because fear is included in the criteria
of both Qi-flowback and generalized anxiety disorder.
A gender difference was observed in the association between
anxiety and Qi-blood-fluid patterns. In females, all the Qi- pat-
terns i.e. Qi-deficiency, Qi-stagnation, and Qi-flowback were
associated with high State anxiety scores, high Trait anxiety
scores, whole anxiety disorder, or generalized anxiety disorder.
In contrast, blood deficiency and fluid retention were not. In
males, Qi-stagnation and Qi-flowback were not associated with
anxiety. Instead, blood deficiency was associated with high
State anxiety scores and generalized anxiety disorder. Espe-
cially, only blood deficiency was associated with generalized
anxiety disorder in males. Since anxiety is not included in
Terasawa’s criteria for blood deficiency, blood deficiency
would be difficult to be taken into account as a differential di-
agnosis. In treating male patients with anxiety, resupply of not
only Qi but also blood would be important.
The extremely high association between eating disorders and
fluid retention in females may be attributed to vomiting and
edema resulting from hypoalimentation.
Strong correlations of more than 0.4 were observed only be-
tween Qi-deficiency and Qi-stagnation and among Qi-flowback,
blood deficiency, and fluid retention in females. The strong
correlation between Qi-deficiency and Qi-stagnation can be
explained by the fact that both are elements of depression as
mentioned above. Besides, since some KMI questions and chief
complaints were assigned to plural kinds of Qi-blood-fluid
patterns, the least common denominators were attributed to
some strong correlations between Qi-blood-fluid patterns. For
example, hypobulia and anorexia as chief complaints or in KMI
were common between Qi-deficiency and Qi-stagnation. This
commonality is supposed to account for the strong correlation
between Qi-deficiency and Qi-stagnation.
Higher correlations were also observed between Qi-defi-
ciency and Qi-flowback in males, although there was only one
common term. The comorbidity of Qi-deficiency and Qi-flow-
back in the present study is directly in line with the previous
report that rectification of Qi without supply of Qi, that is
treatment for Qi-flowback without treatment for Qi-defi- ciency,
may exacerbate gastrointestinal motor dysfunction due to
Qi-flowback (Mori, 1998).
Strong correlation coefficients were observed among Qi-
flowback, blood deficiency, and fluid retention, although
Qi-flowback and blood deficiency have no common terms
among their diagnostic criteria. The comorbidity of these three
can be explained as elements of panic disorder. Many symp-
toms included in the criteria of panic disorder, i.e. numbness,
diaphoresis, palpitation, dizziness, nausea, and chills belong to
Qi-flowback, blood deficiency, or fluid retention. The pathol-
ogy common to the basis of panic disorder may account for the
strong correlations among Qi-flowback, blood deficiency, and
fluid retention. When treating patients with atypical panic
symptoms, diagnosis along the oriental longitudinal axes in
addition to the occidental horizontal axes may be of assistance.
Among Qi-blood-fluid patterns included in Terasawa’s
Qi-blood-fluid scoring system, only blood-stagnation scores
could not be calculated, since most of blood-stagnation score
consists of physical examinations such as tenderness around the
umbilicus. This is the limitation of the present study. A further
investigation with physical examination is necessary, since
C. ENGLERT ET AL.

blood-stagnation has been reported to be associated with vari-
ous kinds of chronic disorders, especially those with fixed
symptoms. Chronic blood stagnation leads to blood deficiency.
In the present study, blood-defi- ciency was shown to be highly
associated with somatoform disorders, most of which were pain
disorder. This result coincides with the previous reports that
that blood pattern including blood stagnation is associated with
chronic pain, especially chronic pelvic pain in females (Chilla,
Knusel, Zollikofer Ch, Huber, & Kubik-Huch, 2006; Ganeshan
et al., 2007).
The specific associations between the Qi-blood-fluid patterns
and some occidental diseases or psychological tests, and the
specific correlations among the Qi-blood-fluid patterns indi-
cated in the present study may be advantageous for alternative
medical treatment in an oriental manner for depression, anxiety
disorder, eating disorder, somatoform disorder and irritable
bowel syndrome.
