About this study
Official title: Clear Hands Challenge: A Single-Group Pilot Evaluation of a Digital Serious Game for Surgical Hand Preparation Training in Nursing Students
This pilot study evaluated the use of Clear Hands Challenge!, a digital serious game designed to support surgical hand preparation training in nursing students. Third-year nursing students participated in a 6-week, single-group educational intervention consisting of 18 planned game sessions.
Participants' surgical hand preparation performance was assessed in a standardized skills laboratory before and after the intervention using the Surgical Hand Preparation Skill Checklist. Performance assessments were video-recorded and independently evaluated by two assessors who were blinded to the assessment time point. Game-use data, including the number and duration of sessions and technical events, were recorded through system logs. Participants' game experience, perceived motivation, perceived ease of learning, and perceived usefulness of corrective feedback were also assessed.
The study was designed as a single-group pilot evaluation. Because there was no control group or random assignment, changes observed between the pre-intervention and post-intervention assessments cannot be attributed specifically to the digital serious game.
Read the detailed description
Clear Hands Challenge! is an HTML5-based digital serious game developed to support the learning and repeated practice of surgical hand preparation procedures among nursing students. The educational content was based on current recommendations for surgical hand preparation and included separate learning activities addressing surgical hand preparation with antimicrobial soap and water and with an alcohol-based surgical hand rub.
The study used a single-group pretest-posttest pilot design. Third-year nursing students who met the eligibility criteria and voluntarily agreed to participate were enrolled. Participants completed a 6-week intervention with 18 planned game sessions, corresponding to at least three sessions per week. The game presented procedural tasks sequentially and provided immediate confirmatory feedback following correct responses and corrective feedback following incorrect responses. Participants were allowed to repeat tasks after receiving feedback. The game generated a formative performance score ranging from 0 to 100; this in-game score was used for educational feedback and was not considered the primary physical performance outcome.
The primary outcome was surgical hand preparation performance demonstrated in a standardized skills laboratory. Physical performance was assessed before and after the 6-week intervention using the researcher-developed Surgical Hand Preparation Skill Checklist. For the primary physical performance assessment, the checklist evaluated surgical hand preparation using antimicrobial soap and water. Participant performances were video-recorded and independently evaluated by two assessors blinded to the assessment time point. Checklist scores were standardized to a 0-100 scale, with higher scores representing better procedural performance.
Intervention exposure and implementation were monitored using system-generated logs, including the number of completed sessions, session duration, completion status, and technical events. Game experience was assessed using the 27-item Gameful Experience Scale (GAMEX). Participants were also asked to report their perceived motivation, perceived ease of learning, and perceived usefulness of the corrective feedback provided by the game.
The study was conducted as a pilot evaluation of the educational intervention and its implementation. The single-group design did not include randomization or a concurrent control group and therefore was not designed to establish the comparative effectiveness of Clear Hands Challenge! or to distinguish the specific effect of the game from other possible influences such as repeated practice, feedback, familiarity with the assessment procedure, or time-related effects.

Clear Hands Challenge! Digital Serious GameBehavioural
Clear Hands Challenge! is an HTML5-based digital serious game designed to support surgical hand preparation training in nursing students. Participants were scheduled to complete 18 game sessions over 6 weeks, with at least three sessions per week. The game included separate educational activities addressing surgical hand preparation with antimicrobial soap and water and with an alcohol-based surgical hand rub. Procedural tasks were presented sequentially. Correct responses received immediate confirmatory feedback, whereas incorrect responses received corrective feedback and an opportunity to repeat the task. The game generated a formative performance score ranging from 0 to 100. Intervention exposure was recorded through system-generated logs.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Surgical Hand Preparation Performance Score
Surgical hand preparation performance was assessed using the researcher-developed Surgical Hand Preparation Skill Checklist during a standardized laboratory performance task using antimicrobial soap and water. Checklist scores were standardized to a 0-100 scale, with higher scores indicating better procedural performance. Performances were video-recorded and independently evaluated by two assessors who were blinded to whether the recording was obtained before or after the intervention. The primary outcome was the within-participant change in the standardized performance score from baseline to the post-intervention assessment.
Measured: Baseline and immediately after the 6-week interventio
