Abstract [en]

The purpose of this study was to investigate the psychometric properties of the Swedish version of Adolescent Dissociative Experience Scale (A-DES), dissociative symptoms among Swedish adolescents, and dissociative symptoms connected to trauma and sexual and physical abuse. A normative group of 400 adolescents aged 12 to 19 years and a clinical group of 20 adolescents with known experienced trauma were given A-DES. A test-retest procedure was conducted with 90 subjects from the normative group. The results showed good reliability, internal consistency and test-retest. Factor analysis in the normative sample (N = 400) resulted in a one factor solution. Correlation between A-DES and other measures of dissociation was high (r = .86). Significant differences for the total sum of A-DES were found in the normative group between adolescents with and without self-reported trauma and between the normative group and the clinical group with known experienced trauma. The Swedish version of A-DES was shown to be a screening instrument with satisfactory psychometric qualities and the capability of capturing dissociative symptoms in adolescents with self-reported trauma as well as clinical cases with identified trauma.

Abstract [en]

The main aim of this thesis has been to investigate trauma and dissociation among Swedish adolescents and to evaluate the psychometric properties such as reliability and various kinds of validity of three screening instruments for assessment of dissociation and other symptoms of post traumatic stress. The three instruments in question have been Dis-Q-Sweden, A-DES and TSCC, the symptoms measured by these instruments are neither easy to capture nor easy for the adolescent to talk about. Therefore these self report scales are essential. A second aim has been to compare the results with results from other countries and to develop preliminary Swedish norms for the clinician to use. Age and gender differences have been looked upon as well as assessed symptoms connected to known experienced trauma/sexual and/or physical abuse and self-reported trauma in normal and clinical populations.

The populations, in this thesis have been children and adolescents age 10 -19 years old from the general population; the clinical groups have had the same age range. All children and adolescents in the clinical groups have been sexually and/or physically abused. Participants have answered the questionnaires Dis-Q-Sweden, A-DES and/or TSCC and their answers have been statistically analysed.

All three instruments have been shown to have good reliability, such as internal consistency and test-retest. Validity has been established through factor analyses, concurrent, and criterion related validity. Clinical groups with known experienced trauma/sexual abuse and/or physical abuse gave significantly higher scores on all the instruments compared to normative groups. Also self-reported trauma in a normative group gave significantly higher scores even if the significances are not as high as between the normative and clinical groups. Girls scored significantly higher than boys in both the clinical and normative groups. Girls in the age range 14-15 years old gave the significantly highest scores on both Dis-Q-Sweden and ADES. Swedish adolescents gave lower mean scores on all three instruments than have been reported from other studies in other countries. The scores from the clinical groups gave about the same mean as have been reported elsewhere.

The conclusion from this thesis is that all the three questionnaires Dis-Q-Sweden, A-DES and TSCC have shown satisfactory psychometrics properties and can very well be used by Swedish clinicians in Child and Adolescents Psychiatry.
