Innovative Web-based Service Platform Called Adult Wellbeing CheckUp (AWC) to Assess Older Adults Wellbeing, Obtain Evidence-based Recommendations, and Receive Support to Take Action.

Change in Self-Reported Actions Taken

Participant-reported actions taken to improve wellbeing in prioritized domains based on recommendations provided during the study. Responses are used to assess follow-through on recommended wellbeing actions.

Time frame: Baseline and Week 24

Change in Adult Wellbeing Assessment Score

Overall wellbeing measured using the Adult Wellbeing Assessment, a 13-item self-report questionnaire designed for older adults. The measure assesses multiple domains of wellbeing, including physical health, mental and emotional wellbeing, social connection, sense of purpose, and daily functioning. Responses are scored to produce an overall wellbeing score, with higher scores indicating better overall wellbeing.

Time frame: Baseline and Week 24

Change in Patient Health Questionnaire-4 (PHQ-4) Score

Mental health symptoms measured using the Patient Health Questionnaire-4 (PHQ-4), a validated 4-item screening tool assessing anxiety and depression symptoms. Scores range from 0 to 12, with higher scores indicating greater symptom severity.

Time frame: Baseline and Week 24

Change in Rapid Assessment of Physical Activity (RAPA) Score

Physical activity level measured using the Rapid Assessment of Physical Activity (RAPA). Aerobic activity (RAPA-1) is scored based on the highest numbered activity level endorsed (1-7), classifying participants from sedentary to active. Strength and flexibility activities (RAPA-2) are recorded separately and categorized as none (0), strength only (1), flexibility only (2), or both strength and flexibility activities (3).

Time frame: Baseline and Week 24

Change in UCLA Loneliness Scale-3 Score

Emotional loneliness measured using the UCLA Loneliness Scale-3, a validated 3-item self-report scale assessing perceived loneliness and social isolation. Scores range from 3 to 9, with higher scores indicating greater loneliness.

Time frame: Baseline and Week 24

Change in Lubben Social Network Scale (LSNS-6) Score

Social isolation measured using the Lubben Social Network Scale (LSNS-6), a validated 6-item measure assessing perceived social support from family and friends. Scores range from 0 to 30, with higher scores indicating larger and more supportive social networks.

Time frame: Baseline and Week 24

Change in Duke Sense of Belonging Short Form Score

Sense of belonging and social connectedness measured using two items adapted from the Duke Social Support/Sense of Belonging questionnaire assessing frequency of contact and time spent with friends or family. The first item assesses frequency of contact with friends or family (in person, by phone, or by video) and is scored on a 5-point scale from 1 (rarely or never) to 5 (daily). The second item assesses the number of times participants spend time with someone who does not live with them in a typical week and is scored on a 4-point scale from 1 (none) to 4 (five or more times). Item scores are summed to produce a total score ranging from 2 to 9, with higher scores indicating greater social connectedness and sense of belonging.

Time frame: Baseline and Week 24

Change in PROMIS Sleep Disturbance Short Form Score

Sleep disturbance measured using the PROMIS Sleep Disturbance Short Form (8a), an 8-item validated self-report questionnaire assessing perceived sleep quality, sleep depth, and difficulty falling or staying asleep over the past seven days. Each item is rated on a 5-point response scale. Responses are summed to produce a raw score ranging from 8 to 40. Higher T-scores indicate greater sleep disturbance.

Time frame: Baseline and Week 24

Change in Topic-Level Impact Ratings

Change in perceived impact of actions taken within prioritized wellbeing domains measured using a single-item question. Participants rate the impact of actions taken in specific domains using a numeric rating scale from 0 to 10, where 0 indicates no impact and 10 indicates very high positive impact on wellbeing. Higher scores indicate greater perceived positive impact of actions taken within the selected wellbeing domain.

Time frame: Week 12 and Week 24

Change in Global Impact of Actions Score

Change in perceived overall impact of actions taken on wellbeing measured using a single-item question. Participants rate the overall impact of actions taken on their wellbeing using a numeric rating scale from 0 to 10, where 0 indicates no impact and 10 indicates very high positive impact on overall wellbeing. Higher scores indicate greater perceived overall benefit from actions taken.

Time frame: Week 12 and Week 24

Reported Barriers to Taking Action

Participant-reported barriers that may limit engagement with recommended wellbeing actions. Barriers are assessed using a survey question allowing participants to select one or more applicable options from a predefined list (e.g., time constraints, lack of resources, lack of motivation, or other challenges).

Time frame: Week 12 and Week 24

Change in Zarit Burden Interview (ZBI-12) Score

Change in caregiver burden among care partner participants measured using the 12-item Zarit Burden Interview (ZBI-12). Each item is rated on a 5-point Likert scale from 0 (never) to 4 (nearly always). Total scores range from 0 to 48, with higher scores indicating greater caregiver burden.
