The House-Tree-Person Test (HTP), developed by John N. Buck in 1947, is a projective psychological assessment tool designed to evaluate an individual's personality through drawings of a house, tree, and person. It provides insights into the subject's emotional state, personality integration, and interaction with their environment, making it particularly useful for individuals who may struggle with traditional assessments. The NEO Personality Inventory, another assessment tool, measures personality traits based on the Five-Factor Model, focusing on neuroticism, extraversion, openness, agreeableness, and conscientiousness.

© Originally developed as an outgrowth of the Goodenough Scale. Florence Goodenough
developed Measurement of Intelligence by Drawings in 1926. The instrument focus was
on the human figure and its purpose was to derive a measure of I.Q.
© It was assumed that the content and quality of the H-T-P was rooted in the individual's
basic personality.
‘© Buck developed a quantitative scoring system to appraise gross classification levels of
intelligence along with at qualitative interpretive analysis to appraise global personality
characteristics
Purpose

inician in obtaining information concerning an individual's sensitivity, maturity,
flexibility, efficiency, degree of personality integration, and interaction with the
environment specifically and generally.

Group testing as a screening device to identify the maladjusted
To evaluate a subject's adjustment prior to entrance into a school or specialized training
program
To appraise personality integration adjustment prior to employment
‘Asa research tool to identify personality factors common to subjects of a given group.
Greater applicability to children.
Good for patients with limited education, limited intellectual ability, low SES, or those
who are shy and withdrawn; those who don’t understand all languages, or who are mute
No time limit
Projective, not a diagnostic test but provide diagnostic indications
Every drawing is different for every person (individualized)
Reliability and validity studies have been most supportive of the cognitive uses of the test
in 3 to 10 year old children.
Disadvantages
Verbal patients are less responsive to graphic techniques than to other projective tests,
like the TAT or Rorschach.
Not “standardized”, No norms/no standardization data available
Psychomotor difficulties such as physical handicaps or tremulousness (geriatric patients)
impede the analysis. Their personality expression is held back by their motoric handicap.
Patients with a paucity of inner life, such as the schizoid patient, provide a barren
personality profile. These patients need something external to stimulate their mental
processes.
House interpretations
Cars: Signs of visitors coming or people in the home leaving.
Lights: Signs to welcome visitors or reveal prowlers.
Open doors or many windows: Strong needs to engage others,
Big windows: especially in the bathroom, could be exhibitionistic desire
Psychotics tends to show ground lines (their need for grounding), clear visions of the
insides of the house (they believe their thoughts and mind are open to view by others),
strange angles (like their strange thought processes), or a house on the verge of a collapse
(like their ego).
Lines and walls: Boundaries and strengths of the ego, Weak lines are weaknesses in the
ego, Strong lines are problems with anxiety and a need to reinforce boundaries.
Roof: Symbolizes the fantasy life, Extra attention to it can indicate extra attention to
fantasy and ideation, Incomplete, tiny, or burning roofs can indicate avoidance ofoverpowering, Frightening fantasies (think about fears of ghosts in the attic - these are
based on the association for us).
‘Windows, doors, and sidewalks: Relate to openness, willingness to interact with others,
and ideas about the environment. Shades, shutters, bars, curtains, and long and winding
sidewalks indicate some unwillingness to reveal
Tree interpretations
Trunk: Represent the ego, sense of self, and the intactness of the personality. Heavy
lines or shadings bark: Anxiety about one's self, small trunks are limited ego strength,
large trunks are more strength.
A tree split down the middle, as if hit by lightening, can indicate a fragmented personality
and serious mental illness, or a sign of organicity.
Limbs are the efforts our ego makes to "reach out" to the world and support "things that
feed us" what we need. Limbs detached are difficulties reaching out, or efforts to reach
ut that we can't control.
Small branches: limited skills to reach out, while big branches may be too much
reaching out to meet needs.
Very pointy branches: represent aggressiveness.
Gnarled branches: "twisted" and represent being "twisted" in some efforts to reach out.
Dead branches: emptiness and hopelessness.
Leaves: Efforts to reach out are successful, since leaves growing mean the tree is
reaching out to the sun and getting food and water.
No leaves: Feeling barren,
Leaves detached from the branches: nurturing we get is not very predictable. Pointy
leaves: aggression, obsessive attention
Detail on the leaves: Obsessive Compulsive tendencies.
Roots: "ground" the tree and people, and typically relate to reality testing and orientation.
No roots: Insecurity and no feeling of being grounded, overemphasized roots can be
excessive concem with reality testing, while dead roots can mean feelings of
disconnection from reality, emptiness, and despair.
Knots or twists in the wood, like gnarled limbs: Some part of the ego is twisted around
some issue.
Height up the tree: represents age of the trauma (so, halfway up for a 10 year old is at
age 5).
Weeping willow trees are more common in depressed people. People with high needs for
nurturance draw apples.
Person interpretations
The person of the same sex is like you, and the person of the opposite sex is what you
may not admit is like you.
Pregnant women or women who have recently given birth may draw naked women, and
women having recently seen the gynecologist may draw naked women.
Usually the same-sex person is drawn first, and the opposite-sexed person second. Some
interpret drawing the opposite-sex first as a sign of gender confusion, which has not been
well-supported.
‘Arms are the way individual reach out to the environment, and hands the way individual
effect it.Open arms: willingness to engage,
Closed arms: defensiveness, disconnected arms are powerlessness...
Pointed fingers or balled fists: aggression,
Hidden or gloved hands: anxiety or antisocial tendencies. It could also be difficulty
drawing good hands.
Legs and feet are also like the roots of trees, and represent grounding and power too. If

NEO Personality Inventory
‘The NEO-Personality Inventory assessment is a psychometric tool used to assess
personality traits.
‘The NEO Personality Inventory uses the ‘Five-Factor Model’ (also known as the ‘Big
Five Personality Test’) to measure personality traits. This theory suggests that each
person’s personality boils down to five core areas — and the test examines these separate
areas of personality to draw conclusions.
‘The NEO-PI test grew out of academic psychology work carried out in the 1970s by
Costa & MeCrae who developed the ‘five trait’ model, following on from work that
started in the 1920s.
By 1978 their work had led them to conclude that there were three broad personality
traits: Neuroticism (N), Extraversion (E) and then Openness (0) — which they called
“Neuroticism-Extraversion-Openness Inventory’ or ‘NEO-I’.
Further work led to the addition of Agreeableness (A) and Conscientiousness (C), with
the test then renamed ‘NEO Personality Inventory’ or ‘NEO-PI’.
Further iterations to the model were developed by the pair during the 1980s and 1990s,
including adding various subsections. The model currently used by academics, clinicians
and recruiters is the ‘NEO PI-3” and can be used by adolescents as young as 10, as well
as those for whom English is not their first language.
A shortened version named ‘NEO FFI-R’ (‘Five Factor Inventory’) is also available. This
test isa shorter version, taking around 15 minutes to complete, with only 60 behavioural
descriptions to consider.
Both the NEO PI-3 and NEO-FFI are untimed tests.
Costa and MeCrae published three updated versions of their personality inventory in
1985 (NEO PI), 1992 (NEO PI-R (or Revised NEO PI), and 2005 (NEO PI-3). The
revised inventories feature updated norms.
The internal consistency of the NEO PI-3 was consistent with that of the NEO PI-R,
with a ranging from .89 to .93 for the five domains, Internal consistency coefficient from
the facets, with each facet scale comprising fewer items than each of the Big Five scales,
were necessarily smaller, ranging from .54 to .83,Scoring

‘Neuroticism (N)
Description of high scores: Individuals who are high in neuroticism have a tendency to
experience negative affects such as fear, sadness, embarrassment, anger, guilt, and disgust. They
are also prone to irrational ideas, are less able to control their impulses, and tend to cope poorly
with stress,
Description of low scores: Individuals who are low in neuroticism are emotionally stable.
They are usually calm, even-tempered, relaxed, and able to face stressful situations without
becoming upset or rattled.
1. Anxiety
2, Angry Hostility
3. Depression
4, Self-consciousness
¢
5. Impulsiveness
6. Vulnerability
(N1) Anxiety
Anxious individuals are apprehensive, fearful, prone to worry, nervous, tense, and jittery. The
scale does not measure specific fears or phobias, but high scorers are more likely to have such
fears, as well as free-floating anxiety. Low scorers are calm and relaxed. They do not dwell on
things that might go wrong.
(N2) Angry Hostility
Angry hostility represents the tendency to experience anger and related states such as frustration
and bitterness. This scale measures the individual's readiness to experience anger; whether the
anger is expressed depends on the individual's level of Agreeableness. Note, however, that
disagreeable people often score high on this scale, Low scorers are easy-going and slow to anger.
(N3) Depression
This scale measures individual differences in the tendency to experience depressive affect. High
scorers are prone to feelings of guilt, sadness, hopelessness, and loneliness. They are easilyhailed Gg

wie a y souls
discouraged and often dejected. Low scorers rarely experience such emotions, but they are not
necessarily cheerful and lighthearted — characteristics associated instead with Extraversion.
(N4) Self-Consciousness
The emotions of shame and embarrassment form the core of this facet of Neuroticism. Self-
conscious individuals are uncomfortable around others, sensitive to ridicule, and prone to
feelings of inferiority. Self-consciousness is akin to shyness and social anxiety. Low scorers do
not necessarily have poise or good social skills, they are simply less disturbed by awkward social
situations,
(NS) Impulsiveness
Impulsiveness refers to the inability to control cravings and urges. Desires (¢.g., for food,
cigarettes, possessions) are perceived as being so strong that the individual cannot resist them,
although he or she may later regret the behavior. Low scorers find it easier to resist such
temptations and have a high tolerance for frustration. The Impulsiveness facet should not be
confused with spontaneity, risk-taking, or rapid decision time.
(N6) Vulnerability
Individuals who score high on this scale feel unable to cope with stress, becoming dependent,
hopeless, or panicked when facing emergency situations. Low scorers perceive themselves as 2
capable of handling themselves in difficult situations.
Extraversion (E)
‘The areas tested here conclude whether you dominate a situation or are quieter and less assertive.
Description of high scores: Individuals who are high in extraversion are sociable; they
like people and prefer large groups and gatherings. Extraverts are assertive, active, and talkative.
‘They like excitement and stimulation and tend to be cheerful in disposition. They are upbeat,
energetic, and optimistic.
Deseri
ion of low scores: Individuals who are low in extraversion are reserved,
independent, and even-paced. Introverts prefer to be alone. Although they are not given to the
exuberant high spirits of extraverts, introverts are not unhappy or pessimistic.
1. Warmth
2. Gregariousness
3. Assertiveness
4. Activity5. Excitement-seeking
6. Positive emotions
(E1) Warmth
Warmth is the facet of Extraversion most relevant to issues of interpersonal intimacy. Warm
people are affectionate and friendly. They genuinely like people and easily form close
attachments to others. Low scorers are neither hostile nor necessarily lacking in compassion, but
they are more formal, reserved, and distant in manner than high scorers.
(E2) Gregariousness
Gregarious people enjoy the company of others — “the more the merrier.” Low scorers on this
scale tend to be loners who do not seek — or who even actively avoid — social stimulation.
(E3) Assertiveness
High scorers on this facet are dominant, forceful, and socially ascendant. They speak without
hesitation and often become group leaders. Low scorers prefer to keep in the background and let
others do the talking.
(E4) Activity
A high Activity score is seen in rapid tempo and vigorous movement, a sense of energy, and a
need to keep busy. Active people lead fast-paced lives. Low scorers are more leisurely and
relaxed in tempo, though they are not necessarily sluggish or lazy.
(E5) Excitement-Seeking
High scorers on this scale crave excitement and stimulation. They like bright colors and noisy
environments. Excitement-Seeking is akin to some aspects of sensation seeking. Low scorers feel
little need for thrills and prefer a lifestyle that high scorers might find boring.
(E6) Positive Emotions
The last facet of Extraversion assesses the tendency to experience positive emotions such as joy,
happiness, love, and excitement. High scorers laugh easily and often. They are cheerful and
‘optimistic. Low scorers are not necessarily unhappy; they are merely less exuberant and high-
spirited.
Openness (0)
Description of high scores: Individuals who are high in openness to experience tend to
have an active imagination, aesthetic sensitivity, attentiveness to inner feelings, preference for
variety, intellectual curiosity, and independence of judgment, Open individuals are curious about
9anf? Av
both inner and outer worlds, and their lives are experientially richer than those of closed
individuals. They are willing to entertain novel ideas and unconventional values, and they
experience both positive and negative emotions more keenly than do closed individuals. Open
individuals are willing to question authority and are prepared to entertain new ethical, social, and
political ideas,
Description of low scores: Individuals who score low on openness to experience tend to be
conventional in behavior and conservative in outlook. They prefer the familiar to the novel, and
their emotional responses are somewhat muted. Individuals with low scores tend to be socially
and politically conservative; this is not be mistaken with intolerance or authoritarian aggression.

Ideas
6. Values
(01) Fantasy
Individuals who are open to fantasy have a vivid imagination and an active fantasy life. They
daydream not simply as an escape, but as a way of creating an interesting inner world for
themselves. They elaborate and develop their fantasies and believe that imagination contributes
to arich and creative life, Low scorers are more prosaic and prefer to keep their minds on the
task at hand.
(02) Aesthetics
High scorers on this scale have a deep appreciation for art and beauty. They are moved by
poetry, absorbed in music, and intrigued by art, They need not have artistic talent, nor even
necessarily what most people would consider good taste, but for many of them, their interest in
the arts will lead them to develop a wider knowledge and appreciation than that of the average
individual
(03) Feelings
‘Openness to feelings implies receptivity to one's own inner feelings and emotions and the
evaluation of emotion as an important part of life. High scorers experience deeper and more
differentiated emotional states and feel both happiness and unhappiness more keenly than others
%do. Low scorers have somewhat muted affects and do not believe that feeling states are of much
importance.
(04) Actions
Openness is seen behaviorally in the willingness to try different activities, go to new places, or
ceat unusual foods. High scorers on this scale prefer novelty and variety to familiarity and routine.
‘Over time, they may engage in a series of different hobbies. Low scorers find change difficult
and prefer to stick with the tried-and-true,
(O5) Ideas
Intellectual curiosity is an aspect of Openness that has long been recognized. This trait is seen
not only in an active pursuit of intellectual interests for their own sake, but also in open-
mindedness and a willingness to consider new, perhaps unconventional, ideas. High scorers
enjoy both philosophical arguments and brain teasers. Openness to ideas does not necessarily
imply high intelligence, though it can contribute to the development of intellectual potential.
Low scorers on the scale have limited curiosity and, if highly intelligent, narrowly focus their
resources on limited topics.
(06) Values
Openness to Values assesses the readiness to reexamine social, political, and religious values.
Closed individuals tend to accept authority and to honor tradition and, as a consequence, are
generally conservative, regardless of political party affiliation. Openness to Values may be
considered the opposite of dogmatism.
Agreeableness (A)
Description of high scores: Individuals who are high in agreeableness tend to be
fundamentally altruistic. They tend to be sympathetic to others and eager to help them, and
believe that others will be equally helpful in return.
Description of low scores: Low scorers are typically disagreeable or antagonistic,
egocentric, skeptical of others’ intentions, and competitive rather than cooperative.
Are you easily led and submissive, or at the other end of the scale, suspicious and
argumentative? This considers whether you are cooperative and a team player, or disagreeable
and untrustworthy.

6. Tender-Mindedness
(Al) Trust
High scorers are disposed to believe that others are honest and well-intentioned. Low scorers on
this scale tend to be cynical and skeptical and to assume that others may be dishonest or
dangerous,
(A2) Straightforwardness:
Individuals with high scores on
s scale are frank, sincere, and ingenuous. Low scorers on this
scale are more willing to manipulate others through flattery, craftiness, or deception, They view
these tactics as necessary social skills and may regard more straightforward people as naive. A
low scorer on this scale is more likely to stretch the truth or to be guarded in expressing his or
her true feelings, but this should not be interpreted to mean that he or she is a dishonest or
manipulative person.
(A3) Altruism
High scorers on the Altruism scale have an active concern for others' welfare as shown
generosity, consideration of others, and a willingness to assist others in need of help. Low
scorers on this scale are somewhat more self-centered and are reluctant to get involved in the
problems of others.
(A4) Compliance
This facet of Agreeableness concems characteristic reactions to interpersonal conflict. The high
scorer tends to defer to others, to inhibit aggression, and to forgive and forget. Compliant people
are meck and mild. The low scorer is aggressive, prefers to compete rather than to cooperate, and
has no reluctance to express anger when necessary.
(AS) Modesty
High scorers on this scale are humble and self-effacing, though they are not necessarily lacking
in self-confidence or self-esteem. Low scorers believe they are superior people and may be
considered conceited or arrogant by others.
(AG) Tender-Mindednessa ae
0 wm”
This facet scale measures attitudes of sympathy and concer for others, High scorers are moved
by others’ needs and emphasize the human side of social policies, Low scorers are more
hardheaded and less moved by sympathetic appeals to pity. They would consider themselves
realists who make rational decisions based on cold logic.
Conscientiousness (C)
Description of high scores: Individuals who are high in conscientiousness are
purposeful, strong-willed, and determined. They are typically involved in planning, organizing,
and carrying out tasks. High conscientiousness is associated with academic and occupational
achievement. High scorers are scrupulous, punctual, and reliable,
Description of low scores: Low scorers are less exacting in applying moral principles,
‘and more lackadaisical in working toward their goals,

‘Competence refers to the sense that one is capable, sensible, prudent, and effective. High scorers
on this scale feel well-prepared to deal with life. Low scorers have a lower opinion of their
abilities and admit that they are often unprepared and inept.
(C2) Order
High scorers on this scale are neat, tidy, and well-organized, They keep things in their proper
places. Low scorers are unable to get organized and describe themselves as unmethodical.
(C3) Dutifulness

(C4) Achievement Striving,
Individuals who score high on this facet have high aspiration levels and work hard to achieve
their goals, They are diligent and purposeful and have a sense of direction in life. Very highscorers, however, may invest too much in their careers and become workaholics. Low scorers are,
lackadaisical and perhaps even lazy. They are not driven to succeed. They lack ambition and
may seem aimless, but they are often perfectly content with their low levels of achievement.
(C5) Self-Discipline
High scorers are able to begin tasks and carry them through to completion, despite boredom or
other distractions. They can motivate themselves to get the job done. Low scorers procrastinate
in beginning chores and are easily discouraged and eager to quit.
(C6) Deliberation
Deliberation reflects the tendency to think carefully before acting. High scorers on this facet are
cautious and deliberate. Low scorers are hasty and often speak or act without considering the
consequences. At best, low scorers are spontaneous and able to make snap decisions when
necessary.
