Experimental: 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.
|
|
Aktiver Komparator: 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.
