Adjustment of Adaptive Behavior Assessment System (ABAS-II): Pilot study in Latvia Malgozata Rascevska, Sandra Sebre University of Latvia, Latvia Tampere, 24-28 July 2007 email: malgozata.rascevska@lu.lv

Why was it chosen to adjust ABAS-II in Latvia? This instrument adjustment is acknowledged inside the more extensive undertaking structure together with the WISC-IV and Child Behavior Checklist (CBC , Achenbach ). These 3 instruments could give Latvian school clinicians superb appraisal strategies to recognize students\' primary mental issue in school setting respect ing insight, versatile conduct and clinical aggravations. Just as of late in Latvia do we have school therapists with enough work experience (5 - 10 years) who could take part in this undertaking , and budgetary backing for investigative exploration. In 2005 we have complet ed adjustment of the Woodcock-Johnson Cognitive Ability Test. ABAS-II is instrument with high dependability and legitimacy.

Introduction The Adaptive Behavior Assessment System – Second Edition (ABAS-II) gives a complete standard referenced appraisal of the versatile abilities of people ages birth to 89 years (Harrison & Oakland, 2003). It was made in USA, the distributer – " Harcourt Assessment". The clinician can utilize the ABAS-II to analyze and group handicaps and scatters; recognize an individual\'s qualities and impediments (Harrison & Oakland, 2005). The a ssessment of an individual is given by different e valuators (guardians, instructors, relatives, the person).

Slide 4

Introduction (continuation) ABAS-II comprises of 5 Forms: Parent/Primary Caregiver Form (ages: 0-5) Teacher/childcare Provider Form (ages: 2-5) Parent Form (ages: 5-21) Teacher Form (ages: 5-21) Adult Form (ages: 16-89) ABAS-II incorporates an evaluation of general versatile working and the 10 versatile expertise ranges indicated by Diagnostic and Statistical Manual of Mental Disorders-Forth Edition – Text Revision (DSM-IV-TR) and American Association of Mental Retardation (AAMR) rules for finding of mental impediment.

Slide 6

The motivation behind this study is t o interpret and socially adjust the ABAS-II (Teacher and Parent Form) for Latvian school youngsters and play out a pilot testing of the psychometric properties of the instruments. The rules prescribed by the International Test Commission (2000) were taken after utilizing two autonomous forward and one back interpretation.

Slide 7

Method Participants The primary specimen was coordinated to the USA institutionalization test of ABAS-II (see Table 1) and comprised of 168 understudies matured from 7 to 21 (age: M=11.87, SD=3.32, half female and half male) from Grade 1 to 12 in ten schools from various Latvian locales. This specimen was partitioned in 6 age subsamples measured in like manner to reporter age bunch extent of USA institutionalization test of the ABAS-II (see Table 1). The second specimen comprised of 26 youngsters with gentle mental impediment (matured from 10 to 19, 38% female and 62% male). The third specimen ( n= 52 ) was drawn from the primary example and coordinated to the second example.

Slide 9

Method (continuation) Instruments Adaptive Behavior Assessment System – Second Edition (ABAS-II) (Harrison, Oakland, 2003): Parent Form (ages 5 - 21) and Teacher Form (ages 5 - 21) Both Forms give scores at three level s : absolute score named General Adaptive Composite (GAC), 3 versatile space scores (Conceptual, Social and Practical), 10 aptitude regions scores (Communication, Functional Academics, Self-Direction, Social, Leisure, Community Use, Home/School Living, Health and Safety, Self-Care, and Work). Guardian Form comprise of 232 things, however Teacher Form 193 things. Each subscale is made out of 15 to 22 things wh ich are evaluated with focuses from 0 to 3.

Slide 10

Method (continuation) Translation system The interpretation procedure was performed in four phases: Two interpreters deciphered the test from English to Latvian dialect (M.Rascevska and S. Sebre) and altered it considering particular s of Latvian society. Two things in Parent Form and three things in Teacher Form were changed completely and 17 things were changed incompletely with one and only or two words (as a rule 8% things were changed in every Form). Ten Latvian school analysts took an interest in extraordinary instructional class about ABAS-II and rehearsed finishing of ABAS-II Forms for a few understudies from guardian and instructor position. After this discourse a few things and subtle elements of direction were rectified.

Slide 11

Method (continuation) Translation strategy The r esearch bunch made extra 2 things for every expertise range in the event that the reasonably unique things w ould not indicate suitable psychometric properties in the pilot study. New things were in clud ed in the test shapes. Latvian-English bilingual Pauls Legzdins (therapist from Toronto, Canada) played out the back interpretation. Subsequent to looking at together forward and back interpretation of ABAS-II three things were modified.

Slide 12

Method (continuation) Procedure of information assembling The Latvian instrument was directed to a pilot study test. From three to six understudies from one class and their folks and instructors were requested that deliberately take an interest in this study. Every guardian and instructor got an envelope with the test shape and could finish it amid a week. The school clinician disclosed to them how to finish the ABAS-II Parent or Teacher Form.

Slide 13

Method (continuation) Procedure of information investigation The factual examinations were performed utilizing SPSS form 15.0. All things in 10 aptitude ranges (independently for Parent and Teacher structure) were examine d from four viewpoints: 1) thing trouble (thing mean), 2) thing separation (amended thing absolute connection), 3) thing element stacking in one variable model of ability territory, 4) thing one-route ANOVA by 6 age bunches. For every one of the 10 ability zones composite scores were computed: 5) the inward consistency (Cron bac h\'s alpha), 6) one-path ANOVA by 6 age gatherings and Post Hoc tests, 7) corroborative element examination - one and three key part investigation with varimax turn for ABAS-II area structure testing.

Slide 14

Results Item investigations ( Parent Form) In the Latvian specimen the larger part of thing trouble lists (61%) were over the basic point 2.40 . O nly 39% things fulfilled psychometric criteria (20%-80% from max point, see Table 2). On the normal thing trouble files of aptitude territories were characteristic that things were too simple , particularly for Self-Care scale (M=2.77, SD=0.42), Communication scale (M= 2.64, SD=0.51), Heath and Safety scale (M=2.54, SD=0.62), Functional Academics scale (M=2.51, SD=0.71), Social scale (M=2.49, SD=0.57), and Leisure scale (M=2.42, SD=0.65).

Slide 16

Item investigations Such results were not particular for the Latvian specimen, comparable results had been in the institutionalization test of the first ABAS-II , in light of the fact that mean scores of ability territories in the Latvia test were lower than relate ing mean s in the USA test (see Figure 1, 2). Along these lines , in further examinations trouble list was not utilized as a fundamental psychometric ind ex of things.

Slide 19

Item examinations Almost all things (98%) indicated great separation records ( inside the interim: r= .20 to .80) Most of the things (87%)manifested component loadings above .40 (all in all variables of aptitude regions), just 13% things demonstrated lower element loadings ( .21 to .39) than the basic point. Just 64% of the things indicated noteworthy contrasts of mean scores (p< .05) among the 6 age bunches (ANOVA for gatherings: 7-8 to 17-21 years of age), somewhat confirmed age legitimacy of ABAS-II things. In any case, crude scores of ability range indicated critical contrasts among age bunches (p<.01) in one-path ANOVA in all expertise regions.

Reliability The inward consistency unwavering quality ( Cronbach\'s alpha) for aggregate size of ABAS-II Latvian form was .98, for expertise zones - above .84, and for 3 areas – above .92 (see Table 3).

Slide 21

Reliability (continuation) Cross-Form Consistency (Parent and Teacher Forms, ages 5-21). The connection coefficients for the abilities ranges between the Parent and Teacher Forms were huge r= .22 to .69 (p< .01), yet lower than in the USA test: r= .60 to .70 (see Table 5). Table 5. Structure c onsistency between the Ratings of Parents and Teachers for ABAS-II in Latvian and US test * see Harrison, P.L., Oakland, T. (2003). Versatile Behavior Assessment System. Second Edition.

Mean scores of expertise territories in Latvian specimen are marginally lower than USA test correspondingly implies (see Table 4, Figure 3) Latvi
