The Riddikulus Nursing Intervention: A Brief, Nurse-Led Intervention to Reduce Student Anxiety in a Randomized Controlled Study

This study investigates the effectiveness of a novel, low-cost, nurse-led psychological intervention called the Riddikulus Nursing Intervention, designed to reduce anxiety levels in university students with moderate anxiety. The intervention was inspired by a metaphorical coping scene from the Harry Potter film series and structured as a single-session, creative, and non-pharmacological approach. During the intervention, participants were asked to generate personal metaphors related to their anxiety and were guided in restructuring these metaphors into less distressing, humorous, or soothing mental images. The process was facilitated by an academic mentor trained in therapeutic communication.

The study was conducted at the School of Foreign Languages of Ege University between December 2023 and June 2024. A total of 1100 students were invited, and 549 agreed to participate. Among students with moderate levels of anxiety, 36 participants were included and the study was completed with them. These participants were randomly assigned to intervention (n=17) and control (n=19) groups. Anxiety levels were assessed at three time points-pre-intervention, post-intervention, and follow-up-using the Visual Analog Scale (VAS) and the Beck Anxiety Inventory (BAI). Data analysis was performed with SPSS 25.0, and participant flow was reported using the CONSORT diagram.

The results revealed a statistically significant reduction in VAS anxiety scores within the intervention group, with a large effect size. However, no significant differences were observed in BAI scores between the groups over time. These findings suggest that the Riddikulus Intervention may be particularly effective in reducing short-term, perceived anxiety in young adults. Participants also reported subjective improvements in emotional state and metaphor transformation following the session.

This study highlights the feasibility and promise of brief, creative, nurse-led interventions for managing moderate anxiety in university settings. Further research with larger sample sizes, repeated sessions, digital delivery formats, and long-term follow-up assessments is recommended to validate and expand upon these findings.
