Due to the increasing use of smartphones and social media in contemporary times, adolescents experience a rapid loss of attention while reading or listening. Educational videos available on the internet are now more frequently utilized as a means of accessing information. The aim of our study is to evaluate the impact of educational videos, educational brochures, and routine verbal counseling on preoperative anxiety and postoperative outcome.
This is a prospective, single-center, three-arm, parallel-group randomized controlled trial conducted at Gazi University evaluating whether the modality of preoperative patient education influences perioperative anxiety and postoperative patient-reported outcomes in adolescents undergoing posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS).
Preoperative anxiety is a common and potentially modifiable contributor to postoperative pain and functional recovery in AIS patients, and the level of anxiety experienced has been linked to the amount and format of information provided before surgery. Because adolescents today increasingly engage with audiovisual content rather than printed text, this trial was designed to compare an animated educational video against a content-matched printed brochure and against routine verbal counseling (control), in order to determine whether the format of preoperative education modifies its effect on anxiety and postoperative outcomes.
After providing written informed consent, participants underwent baseline assessment approximately 3 days before surgery. They were then randomly allocated in a 1:1:1 ratio to one of three preoperative education arms: (1) an animated educational video produced using a commercial cloud-based animation platform, (2) a printed brochure containing text identical to the video narration, or (3) routine verbal counseling delivered by the clinical team. The randomization sequence was generated using an external web-based randomization tool. Allocation concealment was maintained by withholding the sequence from the treating physician and surgeon; a separate study team member communicated the assigned intervention to the researcher who delivered the education session, after the participant's informed consent was obtained.
On the morning of surgery, state anxiety was reassessed to capture the acute perioperative response to the assigned education method. Baseline outcome instruments were re-administered at 3 months postoperatively to assess the persistence of any intervention effect into the recovery period.
Between- and within-group comparisons were conducted using non-parametric methods appropriate to the distribution of the outcome data, supplemented by regression modeling to evaluate the effect of education modality on outcome changes while adjusting for participant age. Full statistical methods are reported in the associated manuscript and are not duplicated here.

Routine verbal preoperative counselling for surgery process
Change in Perioperative (State) Anxiety Level, assessed by the State-Trait Anxiety Inventory (STAI)
State anxiety was measured using the STAI three days before surgery and again on the morning of surgery, and compared among the three preoperative education groups (video, brochure, routine verbal counseling).
Time frame: From baseline (3 days before surgery) to the morning of surgery
Change in Scoliosis Research Society-22 (SRS-22) postoperative outcome scores
Pain domain score of the SRS-22 questionnaire, compared among the three preoperative education groups at the 3-month postoperative follow-up.
Time frame: From baseline (preoperative) to 3 months postoperatively
Plan to share: No — Individual participant data will not be shared because the informed consent obtained from participants and their legal guardians did not include provisions for sharing de-identified data beyond the scope of this study. Additionally, given the small, single-center cohort (n=42) and the pediatric nature of the study population, there is an elevated risk of participant re-identification even after standard de-identification procedures.

Ran from Jun 2024 to primary completion in Sep 2024, 3 months.
Of 2,096 non-industry interventional studies with no phase under Pain, Postoperative, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 23. This study's 3 months is below that.
Counting every sponsor, half of 2,109 studies reached it within 11 months; a quarter within 6 and three quarters within 23.
