Keep Social Randomized Controlled Trial for Young Adults With Cancer

Measured with 8 items from the General Belongingness Scale. Participants will complete a 4-item acceptance/inclusion subscale and 4-item rejection/exclusion subscale weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). Rejection/exclusion items will be reverse coded. We will average responses to the 8 items each week. Social well-being scores will range from 1-5, with higher score are representing better social well-being.

Measured with the 9-item Positive Affect and Well-Being assessment from the Neuro-QOL Item Bank v1.0. Emotional wellbeing will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 9 items each week. Emotional well-being scores will range from 1-5, with higher score are representing better emotional well-being.

Measured with the 11-item ego-resiliency short form (ER-11) focused on the time-varying subscales (active engagement with the world, integrated performance under stress, repertoire of problem-solving strategies) from the 14-item ego-resiliency scale (ER-89). Resilience will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 11 items each week. Resilience scores will range from 1-4, with higher score are representing more resilience.

Measured with 4 items from the Loneliness (Ages 18+) - Fixed Form in the National Institute of Health (NIH) Toolbox® Item Bank v3.0 for adult social relationship scales. Loneliness will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 4 items each week. Loneliness scores will range from 1-5, with higher score are representing more loneliness.

Measured with 3 selected items that focus on feeling stressed, inability to cope, and feeling that difficulties are piling high from the 14-item perceived stress scale (PSS). Perceived stress will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 3 items each week. Perceived stress scores will range from 1-5, with higher score are representing more stress.

Measured with 4 items from the PROMIS-29 Profile v2.0. Anxiety will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 3 items each week. Anxiety scores will range from 1-5, with higher score are representing more anxiety.

Measured with 4 items from the PROMIS-29 Profile v2.0. Depression will be measured weekly, up to 5 times, during the intervention phase of the RCT (weeks 3-7). We will average responses to the 3 items each week. Depression scores will range from 1-5, with higher score are representing more depression.

Measured with 3 items about participants' 1) social opportunity, 2) openness to and 3) initiation of in-person connections. Behavioral adherence will be measured in up to 13 times in each weekly survey and day report (weeks 1-7), including up to 4 assessments during the intro/baseline period and up to 9 assessments for the intervention period. We will analyze each type of behavioral adherence separately. Behavioral adherence (social opportunity) scores will be binary, with 1 representing social opportunity and 0 representing no opportunity. Behavioral adherence (openness, initiation) scores will range from 1-5, with higher score are representing more behavioral adherence.

Measured with 2 adapted items for stranger interactions and 2 adapted items for acquaintance interactions from the Perceived Positivity Resonance Scale. Positivity resonance will be measured up to 13 times in each weekly survey and day report (weeks 1-7), including up to 4 assessments during the intro/baseline period and up to 9 assessments for the intervention period. We will average the responses to the 2 items for each type of interaction (stranger, acquaintance) from each weekly survey and day report. Positivity resonance scores will range from 1-10, with higher score are representing more positivity resonance.
