abstract
The goal for the pre-normative study of the Vineland-II – Survey Form was to examine the reliability and the validity in Turkish children from birth to the age of 9. The reliability for the domains and / or subdomains of the Turkish Vineland II demonstrated the internal consistency (in the range of .81 and .91), the test-retest (range from .92 to .99), and the interinterviewer methods (range from .99 to 100). The evidence for the test content validity of the Turkish Vineland – II domains and the subdomains shown that the mean scores increased by age.

RELIABILITY
aım
The reliability of the Turkish Vineland – II demonstrated in 3 methods:
1.Internal Consistency: The mean split-half reliabilities for Turkish Vineland - II domains and subdomains were generally high ranged from .81 to .91(only lower at ages 1 through 2 for the Community S.).
2. Test-retest Reliability: The test-retest reliability coefficients of the Turkish Vineland – II subdomains were determined very high ranging from .92 to .99 for 8 age groups. The interval between occasions ranged from 10 to 29 days.
3. Inter-interviewer Reliability: The Vineland – II subdomain reliabilities were demonstrated range from .99 to 100 in the same occasions by two different examiners (See Table I- II).
Due to the widely use and the requirements in infant and child psychology and psychiatry fields, the second edition of the Vineland is targeted to gain Turkey in 2005.
ADAPTIVE
BEHAVIOR
The pre-norm and the clinical study of the Vineland II were supported by Ankara University Scientific Research Center under the grant no:
Doll defined adaptive behavior as “the functional ability of the human organism for exercising personal independence and social responsibility” (Doll, 1953).

VALIDITY
In 1888, Vineland Training School was opened as the third institution for the education and care for feeble-minded children so they can live independently by Olin Garrison in Vineland, New Jersey.
Edgar Doll (1935, 1965) was the first person to stress the importance of adaptive behavior (social competence or social maturity), with his PhD thesis, developed the Vineland Social Maturity Scale (VSMS).
Sara Sparrow, David Balla and Domenic Cicchetti (1984, 2005) which psychologists of Yale Child Study Center were developed the items of VSMS and published their first and second editions of the Vineland Adaptive Behavior Scales, respectively.
In Turkey, the adaptation, reliability, and the validity studies of the first edition of the Vineland were investigated for Turkish infants from birth to 4-year-olds by Alpas and Akcakin in 2003.
Test Content Validity: Evidence of the Turkish Vineland – II Test Content Validity demonstrated by the mean scores of the domain and the subdomain increase rapidly from one age group to the next. According to the theoretical structure, the adaptive behaviors and skills of individual typically acquired developmentally (See Table III)
Note: Split-half reliability coefficients are corrected for half-test length by the Spearman-Brown formula

MEtHOD
The results of these pre-normative study shows that the Turkish Vineland – II for Turkish children birth to the age of 9, a reliable tool in the assessment of children’s adaptive behavior.
With use of the Turkish Vineland – II is expected to enrich the studies in the child psychology and development fields, and the assessments for the daily adaptive functioning of primary school and pre-school children, and the infants who cared for at home or kindergarten.

Subdomains Raw Scores, by Age
The eleven Vineland-II subdomains are grouped into four domain composites: Communication, Daily Living Skills, Socialization, and Motor Skills (See Figure I)
By the semistructured interview method, the pre-normative data were collected by supervised 28 examiners (clinical psychologists, psychology 4th grade student, and child development specialist) in 20 to 40 minutes.

SAMPLE
The pre-normative sample consisted of 725 children (354 girls, 370 boys) in 9 age groups. The normally developing children selected from representing three different university hospitals, mother-child health centers for family planning, primary schools and kindergartens in Ankara.
The mothers’ education levels served as the measure of the SES into four groups: 5th grade or lower (207 children); 8th grade (56 children); 11th grade (225 children); 2- and 4-year university degree or higher (230 children).
