One approach to reduce the “response burden” in applied psychological research is to create short versions of inventories. The present study reports the reliability of the Swedish versions of two short inventories; Brief COPE (Carver, 1997) and LOT-R (Scheier, Carver & Bridges, 1994). Brief COPE consists of 14 coping scales comprising 2 items per scale. LOT-R contains six items assessing generalized optimism. Altogether 332 undergraduate students participated in the study. The reliability coefficients indicated that a majority of the Brief COPE scales, as well as LOT-R possessed adequate reliabilities. Overall, the results of the study support the use of the Swedish versions of Brief COPE and LOT-R.
