Beyond positive thinking: A randomized trial of mental contrasting with implementation intentions to curb academic procrastination
The reviewed source is consistent with an existing Brali boundary.
Brali decision: Supports existing guidance. This page summarizes a reviewed evidence boundary; it does not reproduce the source and it does not turn one paper into a universal prescription.
What the source supports
In this specific undergraduate academic-procrastination study, MCII reduced task aversiveness and improved willingness to initiate academic tasks relative to a positive-thinking control, with effects reported through one-week follow-up. Diary reports also provided a behavioral task-initiation signal. It provides narrow corroborating evidence for the obstacle-plus-plan mechanism in an academic setting.
What it does not establish
This trial proves WOOP works for all goals or populations.
The trial establishes long-term goal achievement effects.
The results generalize to workplaces, clinical populations or high-stakes decisions.
WOOP eliminates procrastination.
A one-week follow-up establishes durable behavior change.
Important limitations
The study was single-site and restricted to first-year undergraduates at one private Chinese university.
Twenty of 101 randomized participants were excluded for missing reports or intervention nonadherence, leaving 81 in the final sample (19.8% attrition).
The main psychological outcomes were self-reported; task initiation was derived from participant diary reports rather than an objective academic-performance endpoint.
The context was academic procrastination rather than general goal pursuit.
The follow-up was one week, so long-term persistence is unknown.
The study does not justify generalizing to broad life outcomes, workplaces, clinical treatment, or safety-critical decisions.
Design: Randomized controlled comparison of MCII with a positive-thinking strategy control. The study randomized 101 eligible students; 20 were excluded during the seven-day reporting period for missing reports or intervention nonadherence, leaving 81 in the final sample. Outcomes were measured through pre-test, post-test, seven-day diaries and a one-week follow-up.
Population: 101 eligible first-year undergraduate students at one private Chinese university were randomized; 81 remained in the final analyzed sample after 19.8% attrition.
Exposure / intervention: MCII applied to academic procrastination compared with a positive-thinking strategy control.
This evidence decision is attached to the maintained Brali entry above. The public protocol may be narrowed, reviewed, or kept practical according to the decision.
Editorial note: Use as corroborating boundary evidence only. Reuse the existing research-candidate identity; do not turn this narrow RCT into the primary public claim or imply cross-domain efficacy.
Use the boundary, not just the headline
When an AI agent or a person retrieves this decision, preserve both the supported claim and the unsupported or overstated claims. Dropping the boundary would turn a reviewed source into a stronger claim than Brali actually maintains.
