Short version of the Inventory of Parental Representations, a self-report for attachment assessment among adolescents.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Inventory of Parental Representations (IPR), a self-administered questionnaire, was developed primarily to identify styles of attachment in adolescence. However, it did not present stable psychometric properties in the various American studies carried out. The aim of this study was to adapt the IPR in French and to provide a shorter version with improved psychometric properties and sound content.
methodsThe cross-cultural adaptation and content validity were carried out based on qualitative analysis by an Expert Committee and 10 non-clinical adolescents. For the quantitative analyses a cohort of 535 adolescent volunteers was enrolled, corresponding to 1070 responses, and divided into two groups: development and validation. The study of the metric properties of the adapted version of the IPR was realized in the development group, a sample of 275 responses. In case of mediocre results in the Confirmatory Factor Analysis, the development of a new and reduced IPR structure was planned using a mixed method including Classical Test Theory and Rasch Modelling in the development group. Subsequently, the study of the psychometric properties of the short, adapted version was confirmed in an independent sample of 795 responses (validation group).
resultsOut of 62 items translated, 13 needed adaptations. The analysis of their metric properties produced mediocre results. Content and psychometric property analyses generated two Short version of the IPR in the development group: a paternal scale for Fathers (Short IPRF) with 15 items and a maternal scale for Mothers (Short IPRM) with 16 items. The sound content and good psychometric properties were confirmed in the validation group (Short IPRF: Comparative Fit Index = 0.987, Tucker-Lewis Index = 0.982, Root Mean Square Error of Approximation = 0.027; Short IPRM: Comparative Fit Index = 0.953, Trucker-Lewis Index = 0.927, Root Mean Square Error of Approximation = 0.068). Using Rasch modelling, the attachment was correctly measured overall especially for insecure attachment.
conclusionsA step-by-step process involving led to the generation of two questionnaires: a paternal scale, the Short IPRF, and a maternal scale with the Short IPRM providing opportunities to use this self-questionnaire to assess attachment among adolescents. Further work will provide a solid rating for this new tool.
