Abstract


The Boundary Protection Scale - 14 (BPS-14) represents a new instrument to capture the degree of protection of the mental self-boundary for use in mindfulness training, therapeutic work and scientific research. We assumed a relation between the ability to protect the self-boundary and mindfulness skills. For more efficient use the original version consisting 20 items was abridged and studied with regard to its validity and reliability. Also first reference values were calculated in a sample of 1,089 subjects, consisting predominantly of students. The total score of the abridged version with 14 items shows an acceptable reliability (Cronbach’s ? = 0.79) and a medium correlation (r = -0.48) with mindfulness, measured by means of the Freiburg Mindfulness Inventory (FMI), regarding the convergent validity. Further studies are encouraged, as well as use of the BPS in mindfulness research, social neuroscience or everyday life.
