Domain-IV Cognitive Component
Individuals with autism may lack attention and concentration. They do not respond to instructions
promptly or respond after a considerable delay. On the other hand individuals with autism may also have
special or unusual ability known as, savant ability in some areas like reading, music, memory and artistic
abilities.
b)     Method of Assessment
       i)      Observation
       ii)     Informant interview
       iii)    Testing
Observation
The tester should focus on the individual being tested for the following aspects.
        Ø      Interaction with the caregiver and others
Test Mannual                                        2
        Ø      Quality of social responsiveness in terms of duration, reciprocity.
        Ø      Interest in people and objects
        Ø      Communication
        Ø      Use of sensory modalities
        Ø      Comfort level or distress in relation to others
        Ø      Inappropriate behaviours
For example, testing for “Poor eye contact” should be assessed by observing the individual to see how
frequently she/he makes eye contact, how long eye contact is maintained and its appropriateness to the
age of the person as well as cultural norms. This information should be supplemented by seeking
information from the informants through interview.
Interview
Reliable information from the informant, across different settings, is crucial for proper evaluation. For
example, while testing for delayed response time, use Picture Books/Blocks and ask the child to show
some object/thing/fruit in a picture book or natural surrounding. Observe if the child is responding after
a delay or repeated instructions or prompts are required to elicit a response. Ask for the names or uses of
objects or differences between objects depending on the age of the child.
b) Testing Time
Assessment of persons with autism may take 20-30 minutes
d) Materials
The assessment kit should comprise the following items.
                  1 Car                                    13 Watch

Scoring System
ISAA should be scored as per the scoring system given below.
Each of the 40 test items is to be rated on 5 categories, out of which one is to be checked. These are
further quantified by providing percentages to indicate the frequency, degree and intensity of
behavioural characteristics that are observed. The categories along with the percentages assigned are as
follows:
Rarely (Up to 20%) indicates that the person exhibits this behaviour pattern for up to 20% of the time.
This score is normal for their age and socio-educational background - Score 1.
Sometimes (21 – 40 %) indicates that the person exhibits this behaviour pattern for 21%-40 % of the
time. Some of these behaviours may be a cause for attention and concern, but by and large they may be
considered within normal limits for their age and socio-educational background.
Frequently (41 – 60%) indicates that the person exhibits this behaviour pattern for 41% - 60% of the
time. These behaviours occur with such frequency and regularity that they interfere with the persons'
functioning in daily life. Behaviour at this level will be definitely disabling.
Person may be able to perform activities of daily life with minimum assistance - Score 3.
Mostly (61– 80 %) indicates that the person exhibits this behaviour pattern for 61% - 80 % of the time.
The given behaviour may occur without any discernible stimulus. The behaviour under consideration
occurs so regularly that it significantly hampers the person in performing daily activities.
Always (81% - 100 %) indicates that the person exhibits this behaviour pattern almost all the time, so
much so that it would be considered a major handicap. The behaviour shown is seldom appropriate to the
given situation.

    Indian Scale for Assessment of Autism
I     SOCIAL RELATIONSHIP AND RECIPROCITY
      1. Poor eye contact
      Individuals with autism avoid looking people in the eye. They are unable to maintain eye
      contact as expected for a given age or required of social norms. Eye contact may be unusual such
      as gazing for too long on one spot or looking sideways.
      3. Remain aloof
      Individuals with autism may remain aloof, self-absorbed, withdrawn, and not responsive to
      people or environment. They seem to be preoccupied with their self and be away from the social
      world around. They hardly respond to, or initiate contact with others. There is lack of age
      appropriate pretend play.
      Ask the child if he has friends, whom he likes at home or what he likes to eat etc. Observe how
      responsive the child is to you when you interact.
                                                  5                                       Test Mannual
      6. Inability to respond to social / environmental cues
      Individuals with autism are not responsive to social and environmental demands or
      expectations. They show behavior which is not synchronous with the demands/ requirements of
      the social environment.
      Ask if the child behaves appropriately or not in keeping with what is expected in a given social
      situation and also find out whether the child behaves appropriately when parents take him/her to
      visit friends or relatives, or behaves properly in a market.
II    EMOTIONAL RESPONSIVENESS
      10. Inappropriate emotional response
      Persons with autism do not show the expected feeling in a social situation. They express
      inappropriate emotional responses like laughing when scolded or spanked and inappropriate
      degree of response like excessive crying or laughing that is unwarranted. Emotional reactions
      are unrelated to the event or situation around the individual. They may show unpredictable shift
      in emotions, that is, they may become excited, agitated or distressed for no apparent reason.
Test Mannual                                      6
      triggered off without an apparent reason. At times, it may be exaggerated or atypical. The autistic
      individual may show extreme fear of innocuous objects or events leading to uncontrolled
      behavior.
                                                   7                                       Test Mannual
      19. Produce infantile squeals or unusual noises
      Persons with autism may squeal, make bizarre noises and produce unintelligible speech like
      sounds. They may produce speech like sounds which lack meaning.
IV    BEHAVIOUR PATTERNS
      24. Engage in stereotyped and repetitive motor manners
      Persons with autism may engage in self-stimulatory behavior in the form of flapping of hands or
      fingers, body rocking or using an object for this purpose.
Test Mannual                                      8
    Individuals with autism may be restless with boundless energy which makes it difficult for
    others to control them. The hyperactivity interferes with their learning and performance of tasks.
V SENSORY ASPECTS
                                                 9                                     Test Mannual
      to be unaware of surroundings when thus occupied.
      35 . Insensitive to pain
      Persons with autism may hardly react to pain. They seem not to be distressed or cry when hurt.
      They seem to have high thresholds for pain.
VI    COGNITIVE COMPONENT
      37. Inconsistent attention and concentration
      It is difficult to arouse the attention of individuals with autism. They do not concentrate, and if
      they do, then it may not be on relevant aspects of the object or event. As a result of this, they may
      be inconsistent in their response.
      Ask the child to put the pegs on the board or sort the pieces and put them in their right places on
      the sorting board or fill the bottle with the beads or string the beads in a twine. Check if the child
      can attend and concentrate on the task.
Test Mannual                                       10
        delay. Quick response to instructions is hardly ever to be expected.
        Show picture books/blocks and ask the child to show some object in a picture book. Observe if
        the child is responding after a delay or with repeated instructions. Ask for the name of things or
        objects or its uses or differences between objects depending on the age of the child.
Validity: Validity of ISAA test items was determined by correlating the individual item scores with the
total scores, all the items of the scale were significantly correlated with total scores at 0.001 level, except
one item (A40), namely 'savant ability' which was significant at 0.5 level.
Internal consistency reliability: Internal consistency reliability of ISAA was computed using Cronbach
alpha. The alpha coefficient obtained was 0.93 (p<0.001) for autism group indicating high degree of
internal consistency.
Inter-rater reliability : Inter rater reliability of ISAA was obtained using Pearson Product Moment
Correlation between two raters who independently administered and scored ISAA on 67 randomly
selected children (about 17% of the sample). Correlations between raters varied from 0.62 to 0.81 in
different domains which are equivalent to those found in standard tool, namely, CARS.
Test-Retest Reliability: In order to assess the Test retest reliability of ISAA, 120 subjects (30% of
sample) from autism group were retested after three months. Correlations ranged from 0.60 to 0.85 in
various domains and for the total score it was 0.83 (p<0.001). These results indicate that test-retest
reliability of ISAA is good.
Sensitivity and Specificity: Sensitivity and Specificity of ISAA was computed for investigating its
effectiveness in discriminating autistic and non autistic children as compared to CARS. Further,
                                                      11                                       Test Mannual
Receiver Operating Characteristic (ROC) curve analysis was carried out to assess the discriminant
power of ISAA, using these sensitivity and specificity levels at different cut offs. The ROC analysis also
confirmed the discriminant ability of ISAA, AUC = 0.931 with SE=0.009 at cut off 70.
Based on the ROC cut off score of 70, a diagnostic categorization of ISAA has been established which
aids in the interpretation of total ISAA scores. Using this cut off level, individuals falling below the
score of 70 are categorized as non autistic while those with score of 70 and above are categorized as
autistic.
Norms
To arrive at the taxonomy of ISAA, the scores of 376 children who scored 70 and above from autism
group were analyzed. The mean score was found to be 106.09, range being 70.0 to 181.0 as given below.
Scores ranging from cut off score to mean score (70 to 106) has been classified as mild autism, scores
from mean to Mean+ 2SD (106 to 153) as moderate autism and scores above mean + 2SD (> 153) as
severe autism, as indicated below.

Conclusion:
Indian Scale for Identification of Autism (ISAA) is a standardized tool with good psychometric
properties. It is a reliable and valid tool for making diagnosis of persons with Autism.
