|---|---|---|---|---|
| Digital toolkit | Behavioral | A mobile application providing a science-based digital toolkit and AI chatbot. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Subcomponents of Affect Scale | The Subcomponents of Affect Scale (SAS) is an 18-item measure of affect, divided into nine positive and nine negative adjectives. Positive subscales include calm, well-being, and vigor, while negative subscales include depression, anxiety, and anger. Participants rate each adjective from 0 (not at all accurate) to 4 (extremely accurate) based on their feelings over the past two weeks. Total scores for positive and negative affect are summed from their subscales. | Baseline, bi-weekly for 6 weeks (3 time points) |
| Implicit Theories of Emotion | Implicit theories of emotion were assessed using the Implicit Theories of Emotion Scale, adapted from Dweck's Implicit Theories of Intelligence framework. The scale includes four items assessing beliefs about whether emotions are malleable (incremental) or fixed (entity). Participants rate each item on a 6-point scale from 1 ("Strongly disagree") to 6 ("Strongly agree"). The two entity items are reverse-scored, and all items are averaged to create a single score ranging from 1 to 6, with higher scores indicating stronger endorsement of an incremental (malleable) theory of emotion. | Baseline and 6 weeks post-baseline |
| Loneliness | The UCLA 3-Item Loneliness Scale is a brief measure assessing subjective feelings of loneliness and social isolation. Participants rate each item on a 3-point scale, from 1 (hardly ever) to 3 (often), with higher scores indicating greater loneliness. | Baseline, bi-weekly for 6 weeks (3 time points) |
| Perceived Cohesion | The Perceived Cohesion Scale measures a sense of belonging and morale within a community using a Likert scale from 0 (strongly disagree) to 10 (strongly agree). For our purposes, we use a single-item version: "I see myself as part of the campus community." | Baseline, 6 weeks post-baseline |
| Closeness to University |
| Measure | Description | Time Frame |
|---|---|---|
| Depression (PHQ-2) | The PHQ-2 is an 2-item measure assessing depression severity over the past two weeks. Each item scores from 0 ("not at all") to 3 ("nearly every day"), with total scores from 0 to 6. Higher scores indicate greater depression severity. | Baseline, bi-weekly for 6 weeks (3 time points) |
| Anxiety (GAD-2) |
| Measure | Description | Time Frame |
|---|---|---|
| Net Promoter Score (NPS) | Intervention satisfaction will be assessed using the Net Promoter Score (NPS). Participants in the intervention and control conditions will respond to the item: "How likely are you to recommend the Flourish app / MHA resources to a friend or colleague?" on an 11-point scale from 0 ("Not at all likely") to 10 ("Extremely likely"). Higher scores indicate greater likelihood of recommending the intervention. |

Closeness to one's university was assessed using a modified single-item Inclusion of Other in the Self measure. Participants were shown seven pairs of increasingly overlapping circles and asked, "Which picture best describes your relationship with your university?" Responses range from 1 to 7, with higher scores indicating greater perceived closeness to the university. |
| Baseline and 6 weeks post-baseline |
| Perceived Social Support (PSSS-3) | Perceived social support was assessed using a 3-item short form based on the ACO (PSSS-A6) and adapted from the Multidimensional Scale of Perceived Social Support (MSPSS). Participants rate each item on a 7-point scale from 1 ("Very Strongly Disagree") to 7 ("Very Strongly Agree"). Total scores are summed, yielding a range from 3 to 21, with higher scores indicating greater perceived social support. | Baseline, bi-weekly for 6 weeks (3 time points) |
| Mindfulness (Mindful Attention Awareness Scale) | Mindfulness was assessed using a 5-item short form of the Mindful Attention Awareness Scale (MAAS), modified to assess experiences over the past two weeks. Participants rate each item on a 7-point scale from 0 ("Not at all") to 6 ("Very much"). Items are averaged to create a total score ranging from 0 to 6, with higher scores reflecting lower mindfulness. For interpretability in analyses, this score is reverse-scored so that higher values indicate greater mindfulness. | Baseline and 6 weeks post-baseline |
| Resilience | The Brief Resilience Scale (BRS) is a 6-item measure of stress recovery, rated from 1 (strongly disagree) to 5 (strongly agree). Higher scores indicate a stronger ability to "bounce back" after setbacks. | Baseline, 6 weeks post-baseline |
| Flourishing Scale | The Flourishing Scale is an 8-item measure of psychological well-being. Respondents rate items from 1 ("Strongly disagree") to 7 ("Strongly agree"), yielding a total score range from 8 to 56. Higher scores indicate greater well-being and flourishing. | Baseline, 6 weeks post-baseline |
| Retention / Enrollment Intention | Retention intention was assessed using 2 items evaluating students' likelihood of continuing their enrollment. Participants respond to "How likely are you to stay enrolled next quarter/semester?" on a 5-point scale from 1 ("Very unlikely") to 5 ("Very likely"). A second item asks, "How often have you considered leaving your college/university in the past semester?" rated from 1 ("Never") to 5 ("Very often"). Higher scores on the first item indicate greater intention to persist, while higher scores on the second item indicate greater consideration of leaving. | Baseline, 6 weeks post-baseline |
The GAD-2 (Generalized Anxiety Disorder-2) is a 2-item measure assessing anxiety severity. Each item is rated from 0 ("not at all") to 3 ("nearly every day"), with total scores ranging from 0 to 6. Higher scores indicate greater anxiety severity. |
| Baseline, bi-weekly for 6 weeks (3 time points) |
| Perceived Stress (PSS-4) | The PSS-4 (Perceived Stress Scale-4) is a 4-item measure of perceived stress, rated from 0 ("never") to 4 ("very often"). Scores range from 0 to 16, with higher scores indicating greater stress. | Baseline, bi-weekly for 6 weeks (3 time points) |
| Academic Self Efficacy | The 5-item Academic Self-Efficacy scale measures students' confidence in their ability to succeed academically. Participants rate their agreement with statements such as "I generally manage to solve difficult academic problems if I try hard enough" on a 5-point scale, from 1 (strongly disagree) to 5 (strongly agree). Higher scores indicate greater self-belief in tackling academic challenges and achieving study-related goals. | Baseline, 6 weeks post-baseline |
| Satisfaction With Life | Life satisfaction was assessed using a single-item measure asking, "All things considered, how satisfied are you with your life as a whole?" Participants respond on an 11-point scale from 0 ("Completely dissatisfied") to 10 ("Completely satisfied"). Higher scores indicate greater overall life satisfaction. | Baseline, bi-weekly for 6 weeks (3 time points) |
| School Perceptions | School perceptions are measured using two single-item measures from the Healthy Minds Survey. The first item rates satisfaction with the overall school experience from 1 (very dissatisfied) to 6 (very satisfied). The second item rates agreement with the statement, "At my school, students' mental and emotional well-being is a priority," on a scale from 1 (strongly agree) to 6 (strongly disagree). | Baseline, 6 weeks post-baseline |
| Multi-Dimensional Measure of Trust | The Multi-Dimensional Measure of Trust (MDMT) assesses perceived trustworthiness of the Flourish chatbot, Sunnie, through a set of 10 attributes (Form A), rated from 0 (Not at all) to 5 (Very), with a 'Does Not Fit' option. Only participants in the intervention conditions (Flourish app; Flourish app + buddies conditions) complete this measure. | 6 weeks post-baseline |
| Expectations and Experiences of Chatbots | This measure, adapted from the Working Alliance Inventory - Short Revised (WAI-SR), assesses participants' expectations and experiences with chatbots. Participants rate anticipated and actual interactions across three areas-Goal, Task, and Bond-on a 5-point scale from 1 (seldom) to 5 (always), with higher scores indicating stronger alignment. | Baseline, 6 weeks post-baseline |
| Perceived Empathy of Sunnie | Perceived empathy toward the Flourish chatbot, Sunnie, will be assessed using a 7-item measure. Participants rate each item from 1 ("Strongly disagree") to 6 ("Strongly agree"). Items are averaged to create a composite score, with higher scores indicating greater perceived empathy. This was only presented to those in the intervention conditions. | 6 weeks post-baseline |
| Flourish Buddy Responsiveness | For participants with at least one Flourish Buddy, responsiveness of the selected buddy will be assessed using a 3-item measure assessing how accepted, understood, and cared for participants feel by their buddy. Items are rated from 1 ("Not at all") to 7 ("Very much") and averaged; higher scores indicate greater perceived responsiveness. | Weeks 4 and 6 post-baseline |
| Relationship Satisfaction with Flourish Buddy | For participants with at least one Flourish Buddy, relationship satisfaction with the selected buddy will be assessed using RAS-1, a single item rating overall satisfaction with the relationship from 1 ("Not satisfied") to 5 ("Very satisfied"). Higher scores indicate greater satisfaction. | Weeks 4 and 6 post-baseline |
| Perceived Relationship Improvement | Perceived improvement in the relationship with an existing Flourish Buddy will be assessed using a single item ("To what extent did being Flourish Buddies with this person improve your relationship?"). This item is shown to participants in either Flourish condition who reported having a Flourish Buddy. Participants rate the item from 1 ("Not at all") to 7 ("Very much"). Higher scores indicate greater perceived improvement. | 6 weeks post-baseline |
