Wellbeing Survey |
A battery of surveys each including a number of measures: adolescent mental health and wellbeing; daytime sleepiness; physical and global self-esteem; PE enjoyment; single measures of health-related quality of life and weekly moderate to vigorous physical activity (MVPA); attitudes, social norms, competence, intentions and willingness in relation to physical activity. Approximately 60 questions in total, taking 30 minutes to complete. |
30 minutes: Baseline (June 2017) and final month of the study (June 2018) |

Cognitive Test of Attention and Reaction Time |
This is one of five (computer-based) cognitive tasks developed via jsPsych that are completed by participants at one sitting. It is an attention/ reaction-time task, to appearance of red triangles on the screen. |
10 minutes: Baseline (June 2017) and final month of the study (June 2018) |

Secondary |
Cognitive Test of Memory (Image Associates) |
This is one of five (computer-based) cognitive tasks developed via jsPsych that are completed by participants at one sitting. It is an (image) association of place, person and object (memory) task. |
10 minutes: Baseline (June 2017) and final month of the study (June 2018) |

Secondary |
Eriksen Flanker Test |
This is one of five (computer-based) cognitive tasks developed via jsPsych that are completed by participants at one sitting. It is a (modified) Eriksen Flanker task. |
10 minutes: Baseline (June 2017) and final month of the study (June 2018) |
|
Secondary |
Cognitive Test of Memory (Two-back Image Task) |
This is one of five (computer-based) cognitive tasks developed via jsPsych that are completed by participants at one sitting. It is a two-back image (memory) task (saying whether a picture is the same as the one before last). |
10 minutes: Baseline (June 2017) and final month of the study (June 2018) |
|
Secondary |
Cognitive Test of Executive Function |
This is one of five (computer-based) cognitive tasks developed via jsPsych that are completed by participants at one sitting. It is a task-switching (executive function) task (arms up or arms down characters in relation to shape or colour questions). |
10 minutes: Baseline (June 2017) and final month of the study (June 2018) |

Secondary |
Fitness Assessment (20m Beep Test) |
A distance of 20m is measured; cones are placed at lines indicating the distance. Pupils stand behind one of the lines facing the 2nd line, and begin running when instructed by an audio recording. The pupils continue running between the two lines, turning when signalled by the recorded beeps. After one minute, a sound indicates an increase in speed, and the beeps will be closer together. This continues each minute (level). If the line is reached before the beep sounds, the subject must wait until the beep sounds before continuing. If the line is not reached before the beep sounds, the subject is given a warning and must continue to run to the line, then turn and try to catch up with the pace within two more 'beeps'. The test is stopped if the subject fails to reach the line (within 2m) for two consecutive ends after a warning. Participants are instructed to remember the last number that was called before they stopped and tell the teacher who is recording the scores. |
20 minutes: Baseline (June 2017) and final month of the study (June 2018) |

Physical Activity Measurements |
All pupils will be provided with wrist-worn Axivity AX3 accelerometers, to be worn on the non-dominant wrist, to record their physical activity (PA) during a PE lesson. The AX3 is a tri-axial accelerometer which measures linear acceleration from +/- 2g to +/- 16g range along three orthogonal axes known as 'z' (upward and downward), 'y' (left and right) and 'x' (forward and backward). |
60 minutes: Baseline (June 2017), at 14 weeks, at 28 weeks and final month of the study (June 2018). |
