Abstract
Objective
This randomized controlled trial feasibility study aimed to investigate a single‐session mindset intervention, incorporating third‐wave constructs, within educational settings as a universal tool to promote emotional wellbeing.
Method
Eighty adolescents (age M = 16.63) were randomized to the 30‐min computer intervention or a usual curriculum waitlist. Outcome measures were administered at baseline, posttreatment, 4‐week, and 8‐week follow‐ups.
Results
Student feedback about the intervention and trial procedure was mainly positive. Participants engaged with the intervention content and data were suggestive of possible small–large intervention effects for targeted mechanisms of personality mindset and psychological flexibility. Between‐group differences over time across wellbeing outcomes of self‐compassion, self‐esteem, low mood, and anxiety also yielded some promising results, though assessments of reliable change were less clear. No harm was reported.
Conclusions
The intervention and study design were deemed feasible, though areas for improvement were noted. A full‐scale trial to determine effectiveness is warranted.
