Change in the Patient Reported Outcome Measurement Information System (PROMIS)- Social Isolation from baseline to week 6. This scale assesses perceptions of being avoided, excluded, detached, disconnected from by others. The measure has a Likert Scale (1-5 with 1 being Never and 5 being Always). Raw scores were converted to a T-score, a standardized score with a mean of 50 and a standard deviation of 10. Lower scores indicate lesser social isolation and are therefore a better outcome.

Change in the PROMIS V 2.0 Satisfaction Role Activities from baseline to week 6. This scale assessed caregivers satisfaction level in their participation in relaxation and leisure activities.The measure has a Likert Scale (1-5 with 1 being Not at all and 5 being Very much). Raw scores were converted to a T-score, a standardized score with a mean of 50 and a standard deviation of 10. Higher scores indicate higher satisfaction and are therefore a better outcome.

Change in the Positive Aspects of Caregiving Scale from baseline to week 6. This scale consists of nine items assessing positive consequences of caregiving, each rated on a 0-4 Likert scale (range of scores 0-36), where a higher score reflects a more positive perception of the caregiving experience.

Change in the UCLA Loneliness scale from baseline to week 6. This scale produces a continuous score of the degree to which participants endorse loneliness. The measure has 20 items with a Likert scale of 1-4 with 1 being Never and 4 being Always resulting in a 20-80 scale. Lower scores indicate better outcome.

The Patient Reported Outcomes Measurement Information System (PROMIS)- Positive Affect is a 15-item scale measuring momentary positive affective experiences over the past 7 days. It is a five-point Likert-type scale (i.e.,"not at all, a little bit, somewhat, quite a bit, very much"). Scores are summed to create a raw score. Individual items are positively skewed with 5 options from "Not at all" to "Very much." Higher scores indicate better positive affect and are a better outcome.

3 participants did not complete the baseline Positive Affect Measure

We utilized the Life Enhancing Activities or Caregivers (LEAF) intervention to display that social networks' can be used as a means of reinforcing the positive life skills of the intervention; and that these same skills will enhance social networks, increase mutual satisfaction in social interactions, and boost motivation to reach out to others, thus combatting social isolation.

This group received the intervention for 6 weeks and we looked at outcomes at week 6 post-intervention.

Social LEAF: Social LEAF is an adaptation of the Life Enhancing Activities for Family Caregivers program to focus on social relationships and loneliness. Social LEAF was a six-session group program provided by video-conference that taught caregivers coping skills to improve social relationships and social connection. Social LEAF was delivered in groups of up to 10 caregivers via videoconference and consisted of six weekly hour-long discussion-based classes to teach positive coping skills around improving social relationships. Each week focused on a skill from the original LEAF study adapted to the group and social context.

Change in the Berkman-Syme Social Network Index from baseline to week 6. This scale is used to measure social isolation and loneliness and includes subjective experiences of connection to contacts. This measure is a questionnaire to assess the type, size, closeness, and frequency of contacts in a respondent's current social network. This index is the sum of four binary items (Married (no = 0; yes = 1); close friends and relatives (0-2 friends and 0-2 relatives = 0; all other scores = 1); group participation (no = 0; yes = 1); participation in religious meetings or services (less than or equal to every few months = 0; greater than or equal to once or twice a month = 1)). The total index range is 0-4 with a higher score indicative of better social network.

Caregivers of persons with Lewy-body dementia were randomized to intervention and wait-list control groups. Eight participants did not complete either baseline or the 6-week measure.
