we examined marital satisfaction and marital interaction in Alheimers Disease and frontotemporal dementia couples. Marital satisfaction was assessed using a standard questionnaire. We applied a text analysis methodology to transcripts of these discussions to assess positive and negative emotional language used by patients and caregivers during the interactions. This approach to assessing emotional language is based on the assumption that the words that appear in natural, spontaneous language reflect underlying psychological states and are less prone to the biases of self-report than questionnaire measures.
