Previous research showed that boundary thinness was not only related to openness to experience but also quite strongly to neuroticism. The aim of the present study was to develop a questionnaire measuring boundaries not related to neuroticism. The Boundary Personality Questionnaire (BPQ), consisting of 20 items, showed good reliability and validity by correlating with openness to experience and nightmare frequency. However, there was a strong overlap with the conscientiousness factor that warrants further investigation of the relationship between the boundary concept and the Big Five personality traits. date: 2009 date_type: published id_scheme: ojs official_url: https://journals.ub.uni-heidelberg.de/index.php/IJoDR/article/view/162 ppn_swb: 1403046069 own_urn: urn:nbn:de:bsz:16-opus-93902 language: eng bibsort: SCHREDLMICPSYCHOLOGI2009 full_text_status: none publication: International Journal of Dream Research volume: 2 number: 1 pagerange: 12-19 citation: Schredl, Michael ; Bocklage, Angelika ; Engelhardt, Judith ; Mingebach, Tanja (2009) Psychological boundaries, dream recall, and nightmare frequency: a new Boundary Personality Questionnaire (BPQ).
