Cognition, Happiness, Stress, Psychological
Conditions
Brief summary
The project will enroll up to 10,000 adult volunteers in individualized experiments (N-of-1 trials) designed to assess the individual-level effects of any of five interventions on three outcomes. The five interventions are: gratitude journaling, mindfulness meditation, random acts of kindness, physical activity, and laughter therapy. The three outcomes are stress, cognitive focus, and happiness. Each participant will engage in the selected activity in 3 day intervals, separated at random by 3 day intervals of usual activity, for a total of six 3-day periods (18 days).
Detailed description
N-of-1 trials (single patient crossover experiments) are a uniquely powerful technique for estimating treatment effects in the individual. N-of-1 trials have been offered to hundreds or perhaps thousands of patients worldwide, but never at scale. HackYourHealth is a tool that supports the conduct of simple N-of-1 self-experiments to test if healthy activities that work in general (i.e., mindfulness meditation, physical activity, gratitude journaling, random acts of kindness, and laughter therapy), improve psychological well-being (stress, focus, happiness) in specific individuals. The tool supplies the experimental design, facilitates data analysis, and channels feedback to participants. The tool is flexible enough to support Massive Individualized N-of-1 Experiments (MINEs) at scale. Working with WNYC Radio in New York City, we will recruit and run 18-day N-of-1 trials up to 10,000 individuals. The purpose of this study is to conduct a formative evaluation of HackYourHealth in terms of its perceived usefulness and to explore heterogeneity in intervention response across the sample. We anticipate that the results will: 1) identify useful behavioral interventions for individual participants; 2) help to estimate generalizable treatment effects for the interventions of interest; 3) assess heterogeneity of treatment effects across subgroups; and 4) elucidate the user experience with N-of-1 trials. When complete, the study will support additional proposals designed to assess the utility of MINEs as applied to additional conditions and treatments.

Masking description
The analysis will proceed automatically without knowledge of which 3-day treatment periods were associated with one of the five interventions and which were associated with the subject's usual activities.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Stress | 18 days | How stressed are you feeling today? (single item Likert scale).Stress will be measured using a single Likert-type question that ranges from 0-10, For stress 0 (not at all) represents a better outcome and 10 (as much as possible) represents a worse outcome. |
| Focus | 18 days | How focused are you feeling today? (single item Likert scale).Focus will be measured using a single Likert-type question that ranges from 0-10. For focus 0 (not at all) represents a worse outcome and 10 (as much as possible) represents a better outcome. |
| Happiness | 18 days | How happy are you feeling today? (single item Likert scale).Happiness will be measured using a single Likert-type question that ranges from 0-10. For happiness 0 (not at all) represents a worse outcome and 10 (as much as possible) represents a better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| User burden | Within 1 to 28 days of N-of-1 trial completion | User Burden Scale (UBS) - The UBS is a 20-item scale, with 6 individual sub-scales, that assesses the burden placed on users by computing systems. The 6 burden-related constructs evaluated through the sub-scales are: (1) difficulty of use (2) physical (3) time and social (4) mental and emotional (5) privacy (6) financial The UBS uses two 5-point scales ranging from 0-4 (Never - All of the time; Not at all - Extremely). Total score is a sum of responses to all questions in the scale. A higher score indicates a higher level of user burden. The maximum score is 80 and minimum is 0. User burden can be explored by sub-scales to explore which construct is contributing most to user burden. In such a case, scores for each sub-scale are computed by calculating the mean for items within each sub-scale. |
