The clinical and theoretical papers deal¬
ing
with thepsychological
correlates of de¬pression
havepredominantly
utilized amotivational-affective
model forcategorizing
and
interpreting
the verbal behavior of thepatients.
Thecognitive
processes as suchhave
received little attentionexcept
insofar asthey
were relatedtovariables suchashos¬tility, orality,
orguilt.1
The relative lack of
emphasis
on thethought
processes indepression
may be a reflectionof—orpossibly
acontributing
fac¬tor to—the
widely
heldview thatdepression
isan affectivedisorder,
pureandsimple,
andthat any
impairment
ofthinking
is the re¬sult of theaffective disturbance.2 This
opin¬
ion has been buttressedby
the failure todemonstrate
any consistent evidence of ab¬normalities in the formal
thought
processesin the responses to the standard
battery
ofpsychological
tests.3Furthermore,
the fewexperimental
studies ofthinking
indepres¬
sion have revealed no consistent deviations
other than a retardation in the responses to
"speed
tests"* anda loweredresponsiveness
to a GestaltCompletion
Test.5In his book on
depression,
Kraines° onthe basis of clinical observations indicated several
characteristics

Theobjective
of the presentstudy
has been todetermine
theprevalence
of a

disorder amongdepressed
pa¬tients in
psychotherapy
and todelineate
itscharacteristics.
Animportant corollary
of thisobjective
has been thespecification
of thedifferences
from and the similarities to thethinking
ofnondepressed psychiatric
pa¬tients. This paper will focus
particularly
onthe
following
areas:(1)
theidiosyncratic

Clinical Material
The data for this
study
were accumulatedfrom interviews with 50
psychiatric patients
seen
by
the author inpsychotherapy
or formalpsychoanalysis.
Of thepatients,
fourwere
hospitalized
forvarying periods
oftime
during
the treatment. The rest of thepatients
were seen on anambulatory
basisthroughout
their treatment.The
frequency
of interviews varied fromone to six a week with the median number of interviews three a week. The total
length
of time inpsychotherapy
ranged
from six months to six years; the median was twoyears. In no case did a
single episode
ofdepression
lastlonger
than a year. Alarge
proportion
of thepatients
continued in psy¬chotherapy
for a substantialperiod
of time after the remission of their initialdepressive
episode.
Thirteenpatients
either had recur¬rent
depressions
while inpsychotherapy
or returned topsychotherapy
because of a re¬ currence.In this recurrentdepression
group, six hadcompletely
asymptomatic
intervalsbetween the recurrencesand seven had some
degree
ofhypomanic
elevation. Itwas,there¬fore,
possible
to obtain data from these pa¬tients
during
eachphase
of thecycle.
Of the 50patients
in thesample,
16 weremen and 34 were women. The age range
was from 18 to 48 with a median of 34.
An estimate of their
intelligence suggested
thatthey
were all of at leastbright
averageintelligence.
The socioeconomicstatusof thepatients
wasjudged
to be middle or upper class. Twelveof thepatients
werediagnosed
as
psychotic
depressive
ormanic-depressive
reactions and 38as neuroticdepressive
reac¬tions.
(A
study
based on six of thepatients
in this grouphas
already
beenpublished.7)
Inestablishing
thediagnosis
ofdepres¬
sion thefollowing
diagnostic
indicators wereemployed: (a)
objective signs
of de¬pression
in thefacies,
speech,
posture,
and motoractivity; (b)
amajor complaint
offeeling depressed
or sad and at least 11 ofthe
following
14signs
and symptoms: loss ofappetite,
weight
loss,
sleep disturbance,
loss oflibido,
fatiguability,
crying,
pessi¬
mism,
suicidalwishes,
indecisiveness,
loss of sense ofhumor,
sense of boredom orapathy,
overconcern abouthealth,
excessiveself-criticisms,
and loss of initiative.Patients
showing
evidence oforganic
braindamage
or of aschizophrenic
processand cases in which
anxiety
or some otherpsychopathological
state was morepromi¬
nent than
depression
were excluded fromthis group.
In additionto the group of
depressed
pa¬tients,
a group of 31nondepressed patients
were also seen in
psychotherapy.
The com¬position
of this group was similar to the de¬pressed
group inrespect
to age, sex, and socialposition.
Thesepatients
constituted a"control
group"
for thisstudy.
Procedure
Face-to-face interviews were conducted
during
theperiods
of time when thedepres¬
sions wereregarded
as moderate to severein
intensity.
The author wasactive and sup¬portive
during
theseperiods.
Formalanaly¬
siswas
employed
for thelong-term
patients
except
whenthey
appeared
to beseriously
depressed;
the couch wasutilized,
free as¬sociation was
encouraged,
and thepsychi¬
atristfollowedthe
policy
of minimalactivity.
The recorded data used as the basis for this paper were handwritten notes made
by
theauthor
during
thepsychotherapeutic
inter¬views. These data included
retrospective
reports
by
thepatients
offeelings
andthoughts prior
to the sessions as well asspontaneous
reports of theirfeelings
andthoughts during
the sessions. Inaddition,
several
patients regularly kept
notesof theirfeelings
andthoughts
betweenpsychothera¬
peutic
sessions andreported
these to thepsychiatrist.
During
theperiod
in which these datawere collected handwritten records of the
verbalizations of the
nondepressed patients
were made. These notes wereused forpur¬
poses of
comparison
with the verbal reportsFindings
It was found that each of the
depressed
patients
differed from thepatients
in thenondepressed
groups in thepreponderance
of certain
themes,
which will be outlinedbelow.
Moreover,
each of the othernoso-logical
groups showed anidiosyncratic
idea-tional content which
distinguished
themfrom each other as well as from the de¬
pressed
group. Thetypical
ideational content of thedepressed
patients
was characterizedby
themes of lowself-esteem, self-blame,
overwhelming responsibilities,
anddesires toescape; of the
anxiety
statesby
themes ofpersonal
danger;
of thehypomanic
statesby
themes of
self-enhancement;
and of the hos¬tile
paranoid
statesby
themes of accusationsagainst
others.Although
eachnosological
group showedparticular
types
ofthought
contentspecific
for that group, the formal characteristics and processes of distortion involved in the
idiosyncratic
ideation were similar for eachof these
nosological categories.
The proc¬ esses of distortion and the formal character¬istics will be described in later sections of
the paper.
Thematic Content of
Cognitions
The
types
ofcognitions
* outlined belowwere
reported by
thedepressed patients
tooccur under two
general
conditions.First,
the
typical depressive cognitions
were ob¬ served in response toparticular
kinds of ex¬ternal "stimulus situations." These were
situations which contained an
ingredient,
orcombination of
ingredients,
whose content had some relevance to the content of theidiosyncratic
response. Thisstereotyped
re¬sponse was
frequently
completely
irrelevantand
inappropriate
tothe situation as awhole. Forinstance,
anyexperience
which touchedin any way on the
subject
of thepatient's
personal
attributesmight immediately
makehim think he was
inadequate.
A young man would
respond
withself-derogatory thoughts
to anyinterpersonal
situation in which another person
appeared
indifferent to him. If apasserby
on the street did not smile athim,
he was pronetothink he wasinferior.
Similarly,
a womanconsistently
had thethought
she was a bad mother whenever she saw another womanwith a child.
Secondly,
thetypical depressive
thoughts
were observed in the
patients'
ruminationsor "free
associations," ie,
whenthey
werenot
reacting
to an immediate external stim¬ ulus and were notattempting
to direct theirthoughts.
Theseverely depressed
patients
oftenexperienced
long,
uninterrupted
se¬quences of
depressive
associations,
complete¬
ly
independently
of the external situation.Low
Self-Regard.—The
low self-evalua¬tions formed a very
prominent
part of thedepressed patients'
ideation. Thisgenerally
consisted of an unrealisticdowngrading
ofthemselves in areas that were of
particular
importance
to them. A brilliant academicianquestioned
his basicintelligence,
an attrac¬ tivesociety
woman insisted she had becomerepulsive-looking,
and a successful business¬ manbegan
tobelieve he had no real businessacumenandwas headed for
bankruptcy.
The low
self-appraisal
wasapplied
to per¬sonal
attributes,
such asability,
virtue,
at¬tractiveness,
andhealth;
acquisitions
oftangibles
orintangibles
(such
as love orfriendship)
; orpast
performance
in one's career or role as a spouse or parent. Inmaking
theseself-appraisals
thedepressed
patient
was prone tomagnify
any failuresor defects and to minimize or
ignore
any favorable characteristics.A very common feature of the
self-evaluations was the
comparison
with otherpeople,
particularly
those in his own socialor
occupational
group. Almostuniformly,
inmaking
hiscomparisons,
thedepressed
patient
tended to rate himself as inferior.He
regarded
himself as lessintelligent,
lessproductive,
lessattractive,
lessfinancially
secure, or less successful as a spouse or
parent than those in his
comparison
group.These types of
self-ratings comprise
the*The termcognition is used in the presenttreat¬
ment to refer to a specific thought, such as an in¬
terpretation, a self-command, or a self-criticism.
Thetermis also appliedtowishes (such as suicidal
"feeling
ofinferiority,"
which have been noted in the literature ondepressives.
Ideas
of Deprivation.—Allied
to the lowself-appraisals
are the ideas of destitutionthat were seen in certain
depressed patients.
These ideas were noted in the
patient's
ver¬balized
thoughts
that he wasalone,
un¬wanted,
andunlovable,
often in the face ofovert demonstrations of
friendship
and af¬ fection from otherpeople.
The sense ofdeprivation
was alsoapplied
to material pos¬sessions,
despite
obvious evidenceto thecon¬trary.
S
elf-Criticisms
andSelf-Blame.—Another
prominent
theme in thereported
thoughts
of the
depressed patients
was concernedwith self-criticisms and self-condemnations. These themes should be differentiated from
the low self-evaluations described in the pre¬
vious section. While the low self-evaluation refers
simply
to theappraisal
of themselves relative to theircomparison
group or theirown
standards,
the self-criticisms representsthe
reproaches
they
leveledagainst
them¬ selves for theirperceived shortcomings.
Itshould be
pointed
out,however,
that not allpatients
with low self-evaluations showed self-criticisms.It was
noteworthy
that theself-criticisms,
just
as thelowself-evaluations,
wereapplied
to those
specific
attributes or behaviors which werehighly
valuedby
the individual. Adepressed
woman, forexample,
con¬ demned herself for nothaving
breakfastready
for her husband. On another occa¬sion, however,
shereported
a sexual affair with one of hiscolleagues
without any evi¬ dence ofregret,
self-criticism,
orguilt:
Competence
as a housewife was one of herexpectations
of herself whereas marital fi¬delity
was not.The
patients'
tendency
to blame them¬selves for their mistakes or
shortcomings
generally
had nological
basis. This wasdemonstrated
by
a housewife who took her children on apicnic.
When a thunderstormsuddenly appeared
she blamed herself fornot
having picked
a betterday.
Overwhelming
Problems and Duties.—The
patients consistently magnified
themagnitude
ofproblems
orresponsibilities
thatthey
would consider minor orinsignifi¬
cant when notdepressed.
A
depressed
housewife,
when confronted with thenecessity
ofsewing
"nametags"
on her children's clothes inpreparation
forcamp,
perceived
this asagigantic
undertak¬ing
which would take weeks tocomplete.
When she
finally
didget
to work atit,
she was able tofinish the task in less than aday.
Self-C
ommands andInjunctions.—Self-coercive
cognitions,
while notprominently
mentioned in the literature on
depression,
appeared
to form a substantialproportion
of the verbalizedthoughts
of thepatients
inthesample.
Thesecognitions
consisted of con¬stant
"nagging"
orprodding
to doparticu¬
larthings.
Theprodding
wouldpersist
eventhough
it wasimpractical,
undesirable,
orimpossible
for the persontoimplement
these self-instructions.In a number of cases, the "shoulds" and "musts" were
applied
to an enormous rangeof
activities,
many of which weremutually
exclusive. A housewife
reported
that in aperiod
of a fewminutes,
she hadcompelling
thoughts
to clean thehouse,
lose someweight,
visit a sickfriend,
be a "DenMother,"
get
a full-timejob, plan
the week'smenu, return to
college
for adegree,
spend
more time with herchildren,
take a memorycourse, to be moreactive inwomen's
organi¬
zations,
and startputting
away herfamily's
winter clothes.Escape
and SuicidalWishes.—Thoughts
aboutescaping
from theproblems
of lifewere
frequent
among all thepatients.
Some haddaydreams
ofbeing
a hobo orgoing
toa
tropical
paradise.
Itwasunusual,
however,
thatevading
the tasksbrought
any relief.Even when a
temporary
respite
was takenon the advice of the
psychiatrist,
the pa¬tients were prone to blame themselves for
"shirking
responsibilities."
The desire to escape seemed to be related to the
patients'
viewing
themselves at an im¬passe. On the one
hand,
they
sawthemselvesas
incapable, incompetent,
andhelpless.
On the other handthey
saw their tasks as pon¬ derous and formidable. Their response wasa wish to withdraw from the "unsolvable"
problems.
Severalpatients
spent
consider¬able time in
bed;
somehid under the covers.The suicidal
preoccupations similarly
seemed related to the
patient's conceptuali¬
zation of his situation as untenable orhope¬
less. He believed he could not tolerate a continuation of hissuffering
and he couldsee no solution to the
problem:
Thepsychi¬
atrist couldnot
help
him,
hissymptoms
couldnot be
alleviated,
and his variousproblems
could not be solved. The suicidalpatients
generally
stated thatthey
regarded
suicideas the
only possible
solution for their "des¬perate"
or"hopeless"
situation.Typology
ofCognitive
Distortions Thepreceding
sectionattempted
to delin¬ eate thetypical
thematic content of the ver¬balizations of the
depressed
patients.
A crucial characteristic of thecognitions
withthis content was that
they represented
vary¬ing
degrees
of distortion ofreality.
Whilesome
degree
ofinaccuracy
andinconsistency
would be
expected
in thecognitions
of anyindividual,
thedistinguishing
characteristicof the
depressed patients
was thatthey
showedasystematic
error;viz,
a biasagainst
themselves.Systematic
errors were also noted in theidiosyncratic
ideation of the othernosological
groups.The
typical depressive cognitions
can becategorized
according
to the ways in whichthey
deviate fromlogical
or realistic think¬ing.
The processes may be classified asparalogical
(arbitrary inference,
selectiveabstraction,
andover-generalization), stylis¬
tic
(exaggeration),
or semantic(inexact
la¬beling).
Thesecognitive
distortions wereobserved at all levels of
depression,
fromthe mild neurotic
depression
to the severepsychotic.
While thethinking
disorder wasobvious in the
psychotic
depressions,
it wasobservable in more subtle ways among all
the neurotic
depressed.
Arbitrary interpretation
is defined as the process offorming
aninterpretation
of asituation,
event, orexperience
when there isno factual evidence to
support
the conclusionor when the conclusion is
contrary
to theevidence.
A
patient
riding
on the elevator had thethought,
"He(the
elevatoroperator)
thinks I'm anobody."
Thepatient
then felt sad. Onbeing
questioned by
thepsychiatrist,
he realized there was no factual basis for histhought.
Such misconstructions are
particularly
proneto occurwhen thecues areambiguous.
Anintern,
forexample,
becamequite
dis¬couraged
when he received an announce¬ment that all
patients
"worked-up"
by
the interns should be examinedsubsequently
by
the resident
physicians.
Histhought
onreading
the announcement was, "The chief doesn't have faith in my work." In this in¬stance, he
personalized
the eventalthough
therewas noostensible reasonto suspectthat hisparticular
performance
hadanything
to do with thepolicy
decision.Intrinsic to this
type
ofthinking
is the lack of consideration of the alternative ex¬planations
that are moreplausible
and moreprobable.
Theintern,
whenquestioned
about otherpossible explanations
for thepolicy
decision,
then recalled aprevious
statement
by
his "chief" to the effect that he wanted the residents to have more con¬tact with the
patients,
aspart
of their train¬ing.
The idea that thisexplicitly
statedobjective
was the basis for the newpolicy
had not
previously
occurred to him.Selective abstraction refers to the process
of
focusing
on a detail taken out of context,ignoring
other more salient features of thesituation,
andconceptualizing
the whole ex¬perience
on thebasis of this element.A
patient,
inreviewing
her secretarial work with heremployer,
waspraised
abouta number of
aspects
of her work. The em¬ployer
at onepoint
asked her to discontinuemaking
extra carboncopies
of his letters. Herimmediatethought
was, "He is dissatis¬ fiedwith mywork." This ideabecame para¬ mountdespite
all thepositive
statements he had made.Overgeneralization
was manifestedby
thecon-elusion about their
ability,
performance,
or worthon thebasis ofasingle
incident.A
patient
reported
thefollowing
sequenceof events which occurredwithin a
period
of half an hour before he left the house: Hiswife was
upset
because the children wereslow in
getting
dressed. Hethought,
"I'm a poor father because the children are not betterdisciplined."
He thennoticeda faucet wasleaky
andthought
this showed he wasalsoa poorhusband. While
driving
towork,
he
thought,
"I mustbeapoordriveror other cars would not bepassing
me." As he ar¬rived at work he noticed some other per¬
sonnel had
already
arrived. Hethought,
"Ican'tbeverydedicatedor I would have come
earlier." When he noticed folders and pa¬ pers
piled
uponhisdesk,
heconcluded,
"I'm a poororganizer
because I have so much work to do."Magnification
and minimization refer toerrors in evaluation which are so gross as
toconstitute distortions. As described in the section on thematic content, these processes were manifested
by
underestimation of theindividual's
performance,
achievement orability,
and inflation of themagnitude
of hisproblems
and tasks. Otherexamples
werethe
exaggeration
of theintensity
orsignifi¬
cance of a traumatic event. It was fre¬quently
observed that thepatients'
initial reactiontoanunpleasant
eventwastoregard
it as a
catastrophe.
It wasgenerally
foundon further
inquiry
thattheperceived
disasterwas often a
relatively
minorproblem.
A man
reported
that he had beenupset
because ofdamage
to his house as the resultof a storm. When he first discovered the
damage,
hissequence ofthoughts
were, "The side of the house is wrecked. ... It will costa fortune to fix it." His immediate reaction was that his
repair
bill would be several thousand dollars. Afterthe initial shock haddissipated,
he realized that thedamage
was minor and that therepairs
would cost around$50.
Often inexact
labeling
seemsto contribute to this kind of distortion. The affective re¬action is
proportional
to thedescriptive
la-beling
of the event rather than to the actualintensity
of a traumatic situation.A man
reported
during
histherapy
hourthat he was very
upset
because he had been"clobbered"
by
hissuperior.
On further re¬flection,
he realized that he hadmagnified
theincident and that a more
adequate descrip¬
tion was that his
supervisor
"corrected an error" he had made. Afterre-evaluating
theevent, he felt better. He also realized that whenever he was correctedor criticized
by
aperson in
authority
he was prone to de¬ scribe this asbeing
"clobbered."Formal Characteristics of
Depressive
Cognitions
The
previous
sections haveattempted
tocategorize
thetypical
thematic contents of the verbalizedthoughts
ofdepressed patients
and to present observationsregarding
the processes involved in theconceptual
errorsand distortions.
The inaccurate
conceptualizations
withde¬pressive
content have been labeled"depres¬
sive
cognitions."
This section willpresent
a summary of thespecific
formal characteris¬ tics of thedepressive cognitions
asreported
by
thepatients.
One of the
striking
features of thetypical
depressive cognitions
is thatthey
generally
were
experienced by
thepatients
asarising
asthough they
were automatic responses,ie,
without any
apparent
antecedent reflectionor
reasoning.
A
patient,
forexample,
observed that when he was in a situation in which some¬body
else wasreceiving
praise,
he would"automatically"
have thethought,
"I'm no¬body
. . . I'm notgood
enough."
Later,
when he reflected on his response, he would
then
regard
it asinappropriate.
Nonethe¬less,
his immediate responses to such situa¬ tions continued to be a self-devaluation.The
depressive
thoughts
notonly
ap¬peared
to be"automatic,"
in the sensejust
described,
butthey
seemed, also,
to have aninvoluntary quality.
Thepatients
frequently
reported
that thesethoughts
would occureven when
they
had resolved "not to have them" or wereactively trying
to avoid them.This
involuntary
characteristic wasclearly
exemplified by repetitive
thoughts
of suicidalcontent but was found in a less dramatic way in other
types
ofdepressive cognitions.
Anumberof thepatients
wereabletoantici¬pate
the kind ofdepressive thoughts
that would occur in certainspecific
situations and would prepare themselves in advance tomake a more realistic
judgment
of the situa¬ tion.Nevertheless,
despite
the intention to ward off or control thesethoughts, they
would continue topre-empt
a more rationalresponse.f
Another characteristic of the
depressive
thoughts
is theirplausibility
to thepatient.
At thebeginning
oftherapy
thepatients
tended toaccept
thevalidity
of thecogni¬
tionsuncritically.
It oftenrequired
con¬siderable
experience
inobserving
thesethoughts
andattempting
tojudge
them ra¬tionally
for thepatients
torecognize
themas distortions. It was noted that the more
plausible
thecognitions
seemed(or
the moreuncritically
thepatient regarded them),
thestronger
the affective reaction. It was alsoobserved that when the
patient
was able toquestion
thevalidity
of thethoughts,
the affective reaction wasgenerally
reduced.The converse of this also
appeared
to be true: When the affective reaction to athought
wasparticularly
strong,
itsplausi¬
bility
became enhanced and thepatient
found itmoredifficulttoappraise
itsvalidity.
Fur¬thermore,
once astrong
affect was aroused in response to a distortedcognition,
anysubsequent
distortions seemed tohave anin¬creased
plausibility.
This characteristic ap¬peared
to bepresent
irrespective
of whether the affect wassadness,
anger,anxiety,
oreuphoria.
Once the affective response wasdissipated,
however,
thepatient
could thenappraise
thesecognitions
critically
and rec¬ognize
the distortions.A final characteristic of the
depressive
cognitions
was theirperseveration.
Despite
the
multiplicity
andcomplexity
of life situ¬ations,
thedepressed patient
was prone tointerpret
awide range of hisexperiences
in terms of a fewstereotyped
ideas. The sametype
ofcognition
would be elicitedby highly
heterogeneous experiences.
Inaddition,
these
idiosyncratic
cognitions
tended to oc¬cur
repetitively
in thepatients'
ruminations and stream of associations.Relation of
Depressive Thoughts
to AffectsAs part of the
psychotherapy,
the authorencouraged
thepatients
toattempt tospecify
asprecisely
aspossible
theirfeelings
andthethoughts they
had in relation to these feel¬ings.
A number of
problems
werepresented
inthe
attempt
to obtainprecise description
andlabeling
of thefeelings.
Thepatients
hadno
difficulty
indesignating
theirfeelings
aspleasant
orunpleasant.
In theunpleasant
group of affects
they
werereadily
able tospecify
whetherthey
feltdepressed (or sad),
anxious,
angry, and embarrassed. Whenthey
were asked to discriminate further among thedepressed feelings,
therewascon¬siderable
variability
in the group. Most ofthe
patients
were able to differentiate witha reasonabledegree
ofcertainty
among thefollowing feelings
:sad,
discouraged,
hurt,
humiliated,
guilty,
empty,
andlonely.
In
attempting
to determine the relation ofspecific feelings
to aspecific thought,
thepatients
developed
the routine oftrying
to focus their attentionon theirthoughts
when¬ever
they
had anunpleasant
feeling
or when thefeeling
became intensified. This often meant"thinking
back" afterthey
were awareof the
unpleasant
feeling
to recall the con¬tent of the
preceding thought. They
fre¬quently
observed that anunpleasant thought
preceded
theunpleasant
affect.The most
noteworthy
finding
was that when thethoughts
associated with thede-tThe foregoing features may suggest that the
depressive thoughts are essentially a type of obses¬ sional thinking. The depressive thoughts, however,
differ from classical obsessional thinking in that their specific content varies according to the par¬ ticular stimulus situation and also in that they are
associated with an affective response. Obsessional
thoughts,onthe otherhand,tendtoretainessentially the same "wording" with each repetition are gen¬
erally regarded by the patient as a "strange" or
pressive
affects were identifiedthey
weregenerally
found to contain the type of con¬ceptual
distortions or errorsalready
de¬scribed as well as the
typical depressive
thematic content.
Similarly,
when the af¬fect was
anxiety,
anger, orelation,
the as¬sociated
cognitions
had a contentcongruent
with thesefeelings.
An attempt was made to
classify
the cog¬ nitions to determine whether there wereanyspecific
features that coulddistinguish
among thetypes
ofcognitions
associated re¬spectively
withdepression,
anger, or elation.Itwas
found,
asmight
beexpected,
that thetypical thoughts
associated with thedepres¬
sive affect centered around the ideas that the individual was deficient in some sort of
way.
Furthermore,
thespecific
types
of de¬pressive
affect weregenerally
consistentwith the
specific thought
content.Thus,
thoughts
ofbeing
deserted, inferior,
or derelict in some way, were associated re¬spectively
withfeelings
ofloneliness,
hu¬miliation,
orguilt.
In the
nondepressed
group, thethoughts
associated with the affect ofanxiety

It has been noted that "the
schizophrenic
excels in histendency
to misconstrue the world that ispresented.
. .
."8 While the
validity
of this statement has beensupported
by
numerous clinical andexperimental
stud¬ies,
it has notgenerally
beenacknowledged
that misconstructions of
reality
may also be a characteristic feature of otherpsychiatric
disorders. The presentstudy
indicatesthat,
even in mildphases
ofdepression,
sys¬ tematic deviations from realistic andlogical
thinking
occur. A crucial feature of thesecognitive
distortions is thatthey
consistently
appeared only
in the ideational material thathad a
typically depressive
content; for ex¬ample,
themes ofbeing
deficient in someway. The other ideational material
reported
by
thedepressed patients
did not show anysystematic
errors.The
thinking-disorder typology
outlined in this paper is similar to that described in studies ofschizophrenia.
While some of themost
flagrant schizophrenic
signs (such
asword-salad,
metaphorical
speech,
neolo¬gisms,
andcondensations)
were not ob¬served,
the kinds ofparalogical
processes in thedepressed patients
resembled those de¬scribed in
schizophrenics.8
Moreover,
the same kind ofparalogical thinking
was ob¬served in the
nondepressed patients
in thecontrol group.
While each
nosological
category
showed adistinctive
thought
content, the differences in terms of theprocesses
involved in the deviantthinking appeared
to bequantitative
rather than
qualitative.
Thesefindings
sug¬gest
thatathinking
disordermaybe common to alltypes
ofpsychopathology.
By apply¬
ing
this concept topsychiatric
classification,
it would be
possible
to characterize the spe¬cific
nosological
categories
in terms of thedegree
ofcognitive impairment
and the par¬ ticular content of theidiosyncratic cogni¬
tions.The failure of various
psychological
teststo reflect a
thinking
disorder indepres¬
sion3'4·5 warrants consideration. It may be
suggested
that theparticular
testsemployed
may not have been
adequately designed
for the purpose ofdetecting
thethinking
devia¬ tions indepression.
Since clinical observa¬tion indicates that the
typical cognitive
distortions indepression
are limited tospecific
content areas(such
as self-devalua¬tions),
the variousobject-sorting,
proverb-interpreting,
andprojective
tests may have missed the essentialpathology.
It may be noted that even in studies ofschizophrenia,
the demonstration of athinking
disorder isdependent
on thetype
of test administered and the characteristics of theexperimental
group. Cohenet
al,5
forexample,
foundthatthe
only
instrumenteliciting
abnormal re¬sponses in acute
schizophrenics
was theRorschach test whereas chronic schizo¬
Completion
testaswellas on the Rorschach.The clinical
finding
of athinking
disor¬ der at all levels ofdepression
should focus attention ontheproblem
ofdefining
thepre¬ ciserelationship
of thecognitive
distortions to the characteristic affective state indepres¬
sion. The
diagnostic
manual of the Ameri¬ canPsychiatric
Association(APA)2
definesthe
psychotic
affective reactions in terms of"a
primary,
severe disorder of mood withresultant disturbance of
thought
and behav¬ior,
in consonance with the affect." Al¬though
this is awidely accepted
concept,
theconversewould appeartobeat leastas
plau¬
sible; viz,
that there isprimary
disorder ofthought
with resultant disturbance of affect and behavior in consonance with thecogni¬
tive distortions. This latter thesis is con¬
sistent with the
conception
that the way anindividual structures an
experience
deter¬mines his affective response to it.
If,
forexample,
heperceives
a situation as dan¬ gerous, he may beexpected
torespond
with a consonantaffect,
such asanxiety.
It is
proposed,
therefore,
that thetypical
depressive
affects are evokedby
the erro¬ neousconceptualizations:
If thepatient
in¬correctly perceives
himself asinadequate,
deserted orsinful,
he willexperience
cor¬responding
affects such assadness,
loneli¬ness, or
guilt.
On the otherhand,
thepossibility
that the evoked affect may, inturn, influence the
thinking
should be con¬sidered. It is conceivable that once a de¬
pressive
affect has beenaroused,
it will facilitate the emergence of furtherdepres¬
sive-type cognitions.
A continuous interac¬tion between
cognition
and affect may,consequently,
beproduced
and, thus,
lead tothe
typical
downwardspiral
observed in de¬pression.
Since it seemslikely
that thisinteraction would be
highly
complex,
appro¬priately designed
experiments
would bewar¬ ranted toclarify
therelationships.
A
thorough exposition
of the theoreticalsignificance
of the clinicalfindings
is be¬yond
the scope of this paper. It may betentatively
suggested
that indepression
there is asignificant
rearrangement
of thecogni¬
tiveorganization.
This modifiedorganiza-tion channels a
large proportion
of thethinking
in the direction ofnegative
self-evaluations,
nihilisticpredictions,
andplans
for escape or suicide. It ispostulated
that thisparticular
shift in thethought
content resultsspecifically
from the activation anddominance of certain
idiosyncratic cognitive
patterns
(schémas),
which have a contentcorresponding
to thetypical
depressive
themes in the verbal material. To the ex¬tent that these
idiosyncratic
schémas su¬persede
moreappropriate
schémas in theordering,
differentiation,
andanalysis
of ex¬perience,
theresulting
conceptualizations
ofreality
will be distorted. A morecomplete
formulation of the
cognitive organization
indepression
has beenpresented
in anotherpaper.9
Before this discussion is
concluded,
a fewmethodological
problems
should be men¬tioned. A
question
could beraised,
for ex¬ample,
regarding
thegeneralizability
of theobservations. Since the
sample
consistedlargely
ofpsychotherapy patients
of a rela¬tively
narrow range ofintelligence
and socialindex,
there may be someuncertainty
as to whether thefindings
areapplicable
to thegeneral
population
ofdepressed
patients.
Aprevious
study by
the author and hisco-investigators
ispertinent
to thisquestion.
An
inventory
was derived from the ver¬balized
self-appraisals
of thedepressed
pa¬tients included in the present
study.
Asystematic
study
of the responses to this in¬strument
by
a muchlarger
and moreheterogeneous
clinic andhospitalized sample
demonstrated that the
self-reports
of thepsychotherapy
group wererepresentative
ofthe much broader
group.10
In view of the obvious
methodological
problems
associated withusing
data fromhandwritten notes of
psychotherapy
ses¬sions,
it isapparent
that thefindings
of thepresent
study
will have to besubjected
to verificationby
more refined andsystematic
studies. One
promising approach
has beendeveloped
by
Gottschalk et aln who utilized verbatimrecordings
of five-minuteperiods
of free associationby depressed patients
andsubjected
this material to blindscoring by
trained
judges.
Such aprocedure
circum¬ vents the hazards oftherapist
bias and sug¬gestion
associated with verbal material recorded inpsychotherapy
interviews.Summary
and ConclusionsA group of 50
depressed
patients
inpsychotherapy
and a control group of 31nondepressed patients
were studied to de¬ termine theprevalence
andtypesofcognitive
abnormalities. Evidence of deviation from
logical
and realisticthinking
was found ateverylevel of
depression
from mild neuroticto severe
psychotic.
The ideation of the
depressed patients
dif¬ fered from that of thenondepressed
in theprominence
of certaintypical
themes; viz,
low
self-evaluation,
ideas ofdeprivation,
ex¬aggeration
ofproblems
anddifficulties,
self-criticisms andself-commands,
and wishestoescape or die.
Similarly,
each of thenon-depressed nosological
groups could be dif¬ferentiatedon the basis of their
idiosyncratic
thought
content.Abnormalities were detected
consistently
only
in those verbalizedthoughts
that hadthe
typical
thematic content of thedepressed
groups. The other kinds of ideation did not show any consistent distortion.
Among
the deviations inthinking,
thefollowing
proc¬ esses were identified:arbitrary
inference,
selective
abstraction,
over-generalization,
and
magnification
and minimization.Since
paralogical
processes were also ob¬served in the
idiosyncratic
ideation ofnon-depressed patients,
it wassuggested
that athought
disordermaybe common toalltypes
ofpsychopathology.
The thesis was ad¬vanced that the various
nosological
groups could be classified on the basis of thedegree
of
cognitive
distortion and the characteristic content of their verbalizedthoughts.
In view of the observation that the dis¬
torted ideas of the
depressed
patients
ap¬peared
immediately
before the arousal or intensification of thetypical
depressive
af¬fects,
it wassuggested
that the affectivedis-turbance may be
secondary
to thethinking
disorder. Thepossibility
of areciprocal
in¬teraction between
cognition
and affect wasalso raised.
The thesiswas advancedthat the
cognitive
distortions indepression
result from theprogressive
dominance of thethought
processes
by
idiosyncratic
schémas.By
su¬perseding
moreappropriate
schémas,
theidiosyncratic
schémas force theconceptuali¬
zation of
experience
into certainrigid
pat¬
terns with the consequent sacrifice of
realisticand
logical
qualities.
