Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A parallel-group cluster randomised controlled trial (RCT) will be conducted in ten secondary schools located across New South Wales (NSW), Australia. The intervention will last for approximately 3 months and will involve measurement at baseline, approximately 3- and 12-month post-baseline (long-term follow-up). This study will recruit students (years 7-12), teachers and parents/carers.

The intervention will consist of:
1. The introduction of a school-level policy to restrict access to mobile phones for students during school hours. Schools will develop a school-level mobile phone policy and support the development of an implementation approach for the policy. An implementation approach that is suitable to the school will be selected by the Principal based on methods commonly used by secondary schools that have previously implemented such policies. Implementation methods may vary based on schools’ preferences and may include:
• The introduction of lockable mobile phone pouches upon entry to the school,
• Requiring mobile phones be placed in school bags and in class mobile phone boxes during school hours.

The research team will work with schools to support the implementation of the policy and provide additional support if such assistance is required/requested (e.g. ongoing implementation support, meetings with the staff, and help in developing a smartphone restriction policy). At the end of the school day, students will be able to unlock their devices upon leaving school or remove phones from school bags/in-class boxes.

2. A short education session, in the form of a five-minute video, outlining the rationale, context, and evidence for reducing access to mobile phones during school hours.
In addition to the above, we will also make available for schools interested, an educational video that could be implemented with all teachers (via an existing staff meeting), students (during PDHE lessons), and parents/carers (via existing digital communication channels).

Adherence will be monitored during school-based observations and during support meetings with the schools through the key contact person.

Students will be assessed at baseline assessment, 3-month, and 12-month follow-up.
Secondary outcome [12] 422850 0
In class on-task behaviour (observational assessment).
On-task measure will be assessed using Behavioural Observations of Students at Schools (BOSS) measure. This observational assessment tool will be conducted during classes at baseline assessments, immediately post-intervention and during 12-month follow-up. The BOSS measure divides on-task behaviour into active engaged time (AET; coded when a student is actively engaged in academic responding, e.g., reading aloud, writing in a journal), and passive engaged time (PET; coded when a student is passively attending., listening to a teacher, looking at the black-board while a teacher writes). Both AET and PET are scored using momentary time sampling at the beginning of each 15-second interval. This will be assessed as a composite outcome.

Statistical methods / analysis
Analyses will be undertaken under an intention-to-treat (ITT) framework using 2-tailed statistical tests and an alpha of 0.05. Between group differences on the primary outcome will be assessed using logistic regression models (for binary outcomes) or linear regression models (for continuous outcomes) controlling for baseline values and adjusting for any school level clustering. We will apply multiple imputation methods for missing data at follow-up. Descriptive statistics, including 95% confidence intervals will be used to describe sample characteristics. All analyses will be conducted by a biostatistician using appropriate statistical software (e.g., R, SAS).
