symptoms in comparison with a semistructured
diagnostic interview

Background: In a study of the genetics of ADHD, valid, and reli-
able instruments were needed to describe phenotypic variations in
symptoms of ADHD in the adult relatives of probands diagnosed
with the disorder.
Aims: The aim af the study was to evaluate the validity of short
checklists intended to tap both current and childhood symptoms.
Method: The subjects (89 females and 37 males, aged 17-77 years)
completed DSM-IV based symptom checklists rating their child-
hood and current symptoms. For each adult relative, informants,
most frequently a parent, brother, sister or spouse, completed com-
parable lists. The validity of self-reported and informant-reported
symptoms in childhood and adulthood was evaluated by comparing
the results with an external criterion, namely data gathered by
cxperienced clinicians in semistructured diagnostic interviews
evaluating both childhood and current symptoms.
Besults: For both sexes self-reported symptoms strongly predicted
fesults of the interviews and observer rated symptoms predicted
these results moderately, for both childhood and current symptoms.
Condusion: The results indicate that adults’ self-ratings of their cur-
rent and childhood symptoms of ADHD have acceptable validity
when compared with an external criterion.

Background: The Behavior Assessment System for Children
(BASC; Reynolds & Kamphaus, 1992) is a multidimensional measure
designed to evaluate the behaviour, emotions and self-perceptions
°f children and adolescents aged 2 1/2 to 18 years. It measures both
adaptive and problematic dimensions, as well as behaviour linked
t0 ADD and ADHD.
Ainis: The main objective of this study was to examine the psycho-
metric properties of the Icelandic version of the BASC.
Melhod: The participants were 137 parents and 18 teachers of 117
children aged 6 lo 11. 95 children aged 8 to 11 filled out self-reports.
Results: Reliability was high for all composites and scales and simi-
lar to that of the original version. Correlations between parents’
and teachers’ assessments were in a similar range as in the original
version. Teachers rated boys higher than girls on scales measuring
hyperactivity, aggression and attention problems. They rated girls
higher than boys on scales measuring anxiety, somatization and
social skills. Parents’ assessment was similar to that of teachers, but
there was less difference between sexes.
Conclusions: The Icelandic version of the BASC has good psycho-
metric properties and appears to be a reliable and valid instrument
to use to evaluate behaviour and emotions of Icelandic children
aged 6 to 11.

Translation and cross-cultural adaption of diagnostic
interviews: need for european consensus statement
about standard and validated practices?
Bertrund Lauth. MD, National University Hospital, Department of Child and
Adolescent Psychialry, Dalbraut 12, 105 Reykjavík, Iceland. Páll Magnússon, MSc,
Hannes Pétursson, MD. PhD. FRCPsych.
Background: Many North-American instruments have been shown
to be relevant for systematic and standardised research in general
and clinical populations, and their psychometric properties have
been studied in English-speaking populations. However, the appli-
cation of an instrument in a new cultural group involves more than
simply producing text in another language, administering the trans-
lated instrument, and comparing the results.
Objectives: To analyse the practical problems of cross-cultural
adaptation of diagnostic instruments in child and adolescent psychi-
atry, based on Icelandic experience with the Kiddie-SADS.
Method: The “Kiddie-Schedule for Affective Disorders and Schizo-
phrenia for School-Age Children” (K-SADS-PL“-Present and
Lifetime Version”) is a semi-structured diagnostic interview that
has been used in numerous clinical, naturalistic follow-up, treat-
ment, psychobiological, family-genetic and epidemiological studies.
The process of translation and cross-cultural adaptation of this in-
strument is described, with issues regarding Semantic Equivalence,
Content and Normative Equivalence, Conceptual Equivalence and
Criterion Equivalence.
Kesults: Transfer of validity from one cultural context to another
cannot be taken for granted but has to be demonstrated. Concrete
examples from Icelandic experience will be described. Different
techniques will be discussed to detect and solve construct bias,
method bias, and item bias.
Conclusion: There is a need for a European consensus statement
about standard and validated practices for translating diagnostic
and research instruments.
