Sperimentale: Coping prompt delivered
Decision points at which the randomization outcome is to deliver a brief cognitive-behavioral or acceptance-based coping message.
Message type is selected at random from those eligible in the participant's current context.
Every participant contributes decision points to this condition.
|
A single short message of one to three sentences delivered to the participant's smartphone at a randomized decision point, taking roughly fifteen to thirty seconds to read.
Messages apply cognitive-behavioral techniques including thought records, perspective-taking, decatastrophizing, cost-benefit checks, implementation intentions, and behavioral redirection, or acceptance-based techniques including cognitive defusion, acceptance, values anchoring, urge surfing, and present-moment grounding.
Delivery is capped at four messages per day with a minimum sixty-minute interval and is confined to participant-set waking hours.
Messages may be dismissed without responding.
|
|
Comparatore attivo: No coping prompt or active control message
Decision points at which the randomization outcome is not to deliver a coping message.
A brief neutral, non-directive acknowledgment message may be delivered as an active control so that receiving any message can be separated from receiving a coping message.
Every participant contributes decision points to this condition.
|
A brief neutral acknowledgment message matched to the coping messages on delivery mechanism and approximate length, containing no coping technique or behavioral suggestion.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Momentary urge to post or reply reactively, score on a 7-point scale.
Lasso di tempo: Within 2 hours after each randomized decision point, across weeks 2 to 5.
|
Self-reported urge to post or reply about something upsetting, rated 1 to 7 at the first check-in within two hours after a randomized decision point.
Higher scores indicate greater urge.
Analyzed as a causal excursion effect comparing decision points at which a coping message was delivered with those at which it was not.

Momentary urge to drink alcohol, score on a 7-point scale.
Lasso di tempo: Within 2 hours after each randomized decision point, across weeks 2 to 5.
|
Self-reported current urge to drink alcohol, rated 1 to 7 at the first check-in within two hours after a randomized decision point.
Higher scores indicate greater urge.
Analyzed as a causal excursion effect.
|
Within 2 hours after each randomized decision point, across weeks 2 to 5.
|
|
Momentary emotional influence on eating, score on a 7-point scale.
Lasso di tempo: Within 2 hours after each randomized decision point, across weeks 2 to 5.
|
Self-reported rating of how much emotions influenced eating since the previous check-in, rated 1 to 7 at the first check-in within two hours after a randomized decision point.
Analyzed as a causal excursion effect.
|
Within 2 hours after each randomized decision point, across weeks 2 to 5.
