Gratitude interventions have been studied in randomized trials and meta-analyses. Effects are generally small on average and differ by outcome, intervention, and study design.
This summary describes a meta-analysis of gratitude interventions across 28 countries. It does not mean a journal will produce the same result for every person or replace clinical care.
Numbers about phone use and wellbeing are easy to overinterpret. A measure of use does not by itself describe whether that use was intentional, required, enjoyable, or harmful. A research association does not prove one factor caused another. This page keeps those distinctions visible so readers can use the result as context rather than a diagnosis or prediction.
The result applies to the source’s defined population and period, not every age group, country, or person.
Statistics about use frequency or wellbeing do not diagnose addiction, ADHD, anxiety, depression, or another condition.
Unless a source used a design that supports causal inference, associations should be read as associations.
This data does not establish that a particular app or intervention will change an outcome for an individual.
Dia Key uses a small, self-directed routine: a selected-app boundary and a short gratitude entry. It does not claim to treat a condition or guarantee an outcome. If you use a phone boundary, start with one context, preserve essential access, and review whether the setting makes the next action more intentional. See the screen-time guide and app-blocking hub for practical options.
