Validation of the inventory of interpersonal problems - Results of a representative study in East- and Westgermany

The Inventory of Interpersonal Problems (IIP) was developed in the USA in t he late 1970s and in the mean time has become a well-established instrument applied in numerous clinical studies in German speaking countries under th e name "Inventar zur Erfassung interpersonaler Probleme". The test manual w as published in German in 1994, but without the corresponding standardisati on for a German-speaking population. The present study fills this gap. In a representative study the IIP was completed by 2025 West Germans and 1022 E ast Germans aged 14-92 years. The representative norms are given and the ps ychometric dimensions of the questionnaire adjusted for this sample. As a c ontribution to testing validity the results were also related to the scores of a number of other tests completed by the same sample (Giessen Test - GT ; Giessener Beschwerdebogen - GBB: Fragebogen zur Lebenszufriedenheit - FLZ ; Angstbewaltigungsinventar - ABI and the Fragebogen zum erinnerten elterli chen Erziehungsverhalten [FEE]). The relevant results will be reported.
