 The Communication Burden Scale (COM-B) was developed to assess feelings of burden in caregivers of adults with aphasia. The purpose of this study was to examine the validity and reliability of the COM-B and its clinical application as well.

 Three hundred and fifty-three informal caregivers of adults with aphasia participated in the study. Factor-analytic statistical techniques were used to demonstrate construct validity. Common variance that represents caregiver burden, was identified by the following four factors. They were burdens related to:1.caregivers' activity restriction, 2.language impairment of adults with aphasia, 3.cognitive and emotional impairment of adults with aphasia, and 4.responsibility for household management. Each of these factors consists of a group of items with high internal consistency.

 The test-retest reliability of the COM-B was examined using another group of caregivers with similar background. The results confirmed a high reliability of r=.78~.84. Clinical application of the COM-B was examined by comparing the COM-B ratings of caregivers with those of speech-language-hearing therapists (SLHTs). It became clear that there was rarely complete agreement between the ratings of the caregivers and the ratings of the SLHTs. The results can be interpreted as showing the difference between the two groups in the perception of burden felt by caregivers.

 In summary, the COM-B's validity and reliability were confirmed and it was suggested that the use of the COM-B may broaden the view of SLHTs who work with adults with aphasia and their family.
