Abstract
Zusammenfassung.Theoretischer Hintergrund: Die Störung der Paruresis besteht in dem Unvermögen, auf öffentlichen Toiletten zu urinieren. Sie ist bislang in der Sozialen Phobie-Forschung nur wenig beachtet worden, was nicht zuletzt an dem Mangel an Messinstrumenten liegen könnte. Fragestellung: Entwicklung und Überprüfung der Paruresis-Skala (PARS). Methode: An einer Stichprobe von N = 180 über das Internet rekrutierten Probanden, die vier Gruppen zugeordnet wurden (Paruresis, Nichtgeneralisierte Soziale Phobie, Generalisierte Soziale Phobie, Kontrollgruppe), wurde eine Item- und Faktorenanalyse durchgeführt sowie konvergente und diskriminante Validität bestimmt. Ergebnisse: Die PARS weist sehr gute Kennwerte der Reliabilität auf, korreliert mit urologisch bedingten Miktionsbeschwerden nur schwach und kann zwischen den an Paruresis und den an reiner sozialer Phobie leidenden Probanden trennen. Schlussfolgerung: Die PARS ist als Messinstrument im Forschungskontext geeignet.
Abstract.Background: Paruresis is the inability to urinate in public restrooms. It has hardly been studied at all to date within social-phobia research, possibly due to the lack of assessment methods. Objective: Development and evaluation of the Paruresis Scale (PARS). Methods: In an internet-based study N = 180 subjects were divided into four groups (paruresis, non-generalized social phobia, generalized social phobia, control subjects). Items of the PARS were analyzed and examined by factor analysis and convergent and discriminant validity were calculated. Results: PARS shows a high reliability, correlates only weakly with somatically based lower urinary tract symptoms, and discriminates between subjects suffering from paruresis and subjects suffering from pure social phobia. Conclusions: PARS is an adequate questionnaire for research purposes.
