Abstract

Objective:

There is emerging evidence that cognitive behavioral therapy (CBT) can be effective for treating anxiety and depression in people living with dementia (PLWD). Discriminating between thoughts and feelings is a critical element of CBT and also of relevance to emotional understanding more generally. The aim of the present study was the structured adaptation and preliminary validation of an existing measure of thought–feeling discrimination for use in PLWD.

Methods/Design:

The Behavior Thought Feeling Questionnaire (BTFQ) was adapted via expert and service-user consultation for use in PLWD. One hundred two PLWD and 77 people aged over 65 years who did not have measurable cognitive impairments completed the adapted measure along with two measures of emotional recognition and reasoning. The factor structure of this measure was examined and the measure reduced.

Results:

Factor analysis suggested a two-factor solution with thought and feeling items loading on separate factors. The behavior items were not included in scoring due to high cross-loading and ceiling effects, leaving a 14-item measure with two subscales. Thus, an adapted measure was created (named the BTFQ-D), which showed moderate convergent validity in the PLWD but not the older adult sample. Both thought and feeling subscales showed good internal consistency.

Conclusions:

The BTFQ-D showed preliminary validity as a measure of thought–feeling discrimination in PLWD. It may have utility in measuring readiness for CBT as part of clinical assessment. Further validation is required.
