The usability of the web application will be measured by the System Usability Scale (SUS). This scale is a 10-item assessment of the usability of a system, helping identify areas for improvement. Response options range from 1 - Strongly Disagree to 5 - Strongly Agree. Scores range from 0-100, with higher scores indicative of greater usability.

The Acceptability of the LMH-4-DCP Application as Measured by a Survey That Measures the Participants Satisfaction and Acceptability of the Application.

The acceptability of the LMH-4-DCP application was assessed among caregiver participants assigned to the intervention arm using a study-specific survey evaluating usability, engagement, acceptability, and suggestions for improvement. Participants rated their agreement with statements such as "I enjoyed my experience using the LMH-4-DCP application" on a five-point Likert scale ranging from 1 - Strongly Disagree to 5 - Strongly Agree. Total scores range from 8 to 40, with higher scores indicating greater satisfaction and acceptability of the intervention.

Response options range from 1 - Not At All to 4 - Completely. Scores range from 6-24, with higher scores indicative of poorer relational quality.

Change in Relationship Quality as Measured by the Mutuality Scale.

The second measure of relationship quality will be the validated 15-item Mutuality Scale, which measures the extent of positive aspects of caregiving. Response options range from 0 - Not At All to 4 - A Great Deal. Scores range from 0-60, with higher scores reflecting greater levels of mutuality.

Change in Relationship Quality as Measured by the Relationship Rewards Scale.

The third measure of relationship quality will be the 8-item validated Relationship Rewards Scale (RRS) instrument, which includes two subscales assessing caregivers' perceptions of relationship quality prior to the care-recipient's diagnosis ("pre-illness") and at the current time ("current relationship"). Responses range from 1 - Never to 4 - Always. Scores for each subscale range from 4-16, with higher scores indicating greater perceived relationship quality.
