    Psychometric properties of the PsychoSomatic Problems scale: a Rasch analysis on adolescent data2008In: Social Indicators Research, ISSN 0303-8300, E-ISSN 1573-0921, Vol. 86, no 3, 511-523 p.Article in journal (Refereed)
    Abstract [en]

    The PsychoSomatic Problems (PSP)-scale is built upon eight items intended to tap information about psychosomatic problems among schoolchildren and adolescents in general populations. The purpose of the study is to analyse the psychometric properties of the PSP-scale by means of the Rasch model, with a focus on the operating characteristics of the items. Cross-sectional adolescent data collected in Sweden at six points in time between 1988 and 2005 are used for the analysis. In all more than 15,000 students aged 15–16 are included in the analysis. Data were examined with respect to invariance across the latent trait, Differential Item Functioning (DIF), item categorisation and unidimensionality. The results show that the PSP-scale adequately meets measurement criteria of invariance and proper categorisation of the items. Also the targeting is good and the reliability is high. Since the scale works invariantly across years of investigation it is appropriate for re-current monitoring of psychosomatic health complaints in general populations of adolescents. Taking DIF into account through principles of equating provides a scale that shows no statistically significant signs of gender-DIF enabling invariant comparisons also between boys and girls.

    Abstract [en]

    The Strength and Difficulties Questionnaire (SDQ) is increasingly used as a survey instrument for tapping information about mental health problems among children and adolescents. According to most of the evaluations of the SDQ, the instrument shows sound psychometric properties. The purpose of this paper is to analyse the properties of five subscales of the self-reported SDQ by using latent trait theory and the Rasch model, with a focus on the operating characteristics of the items. The analysis is based on cross-sectional data collected in Sweden in 2003 and 2004 among adolescents aged 12–18. In all, six sets of data including 8838 students are used. The analysis detected problems in all dimensions. In particular, the conduct problems scale seemed problematic. By removing misfitting items some improvements were achieved in the post-hoc analysis. However, the ambiguous nature of some items is a major cause for concern but also a potential for improvements of the instrument. It is therefore recommended that each of those items that include two sentences is split into two new items, in order to be tested in forthcoming studies.
