Self-regulation prompts can increase fruit consumption: A one-hour randomised controlled online trial
Abstract
OBJECTIVE: The purpose was to examine whether a 1-h intervention would help increase fruit consumption in motivated individuals and to study the role of self-regulatory mechanisms in the behaviour change process, with a particular focus on dietary planning and action control. METHODS: A randomised controlled trial compared a 1-h online intervention with controls in 791 participants. Dependent variables were fruit intake, planning to consume and dietary action control. RESULTS: Experimental condition by time interactions documented superior treatment effects for the self-regulation group, although all participants benefited from the study. To identify the contribution of the intervention ingredients, multiple mediation analyses were conducted that yielded mediator effects for dietary action control and planning. CONCLUSIONS: A very brief self-regulatory nutrition intervention was superior to a control condition. Dietary planning and action control seem to play a major role in the mechanisms that facilitate fruit intake.

Significant improvements in self-regulation can be observed over just a week.
“Furthermore, a study conducted by Lange, Richert, Koring, Knoll, Schwarzer and Lippke [31] showed that significant improvements in self-regulation can be observed over just a week.”
This is the first study to show that a planning technique within a habit intervention improves self-regulatory skills.
“However, this is the first study to show that a planning technique within a habit intervention improves self-regulatory skills.”
Other intervention studies applying planning techniques found changes in self-regulatory skills over short and long periods.
“This is comparable to other intervention studies that have applied planning techniques, in which changes in self-regulatory skills were found over a short [30, 31] and long period of time [32].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
