Description of intervention(s) / exposure
This is a prospective, cross-sectional case-control study. Children between the ages of 5-12 will be taken to the study as a case and control group, and the game will be performed together with the questionnaires.
The case group consisted of 54 children (18 ADHD combined, 18 ADHD Inattentive, 18 ADHD Hyperactive), aged between 5 and 12 years, who were admitted to the Pediatric Psychiatry Outpatient Clinic for the first time. The case group will be newly diagnosed, previously untreated.
Participants and the parents of them will be informed in detail about the study.
After the clinical interview, the Conners' ADHD Rating Scale will be applied to the parents of children who have agreed to participate in the study and who have been informed in written and orally. The Battleship will be played on the computer for 20-40 minutes. Researchers will teach the children to play the game. After the children learn how to play the game, the game will be played by the children without any help. The player will play the game alone. The player will not be a competitor against the player or another player. When the game is completed, children will be able to learn their score. At the end of each game, the child will be asked if he or she would like to play another game. The children will play eight times the game. The total testing duration will be approximately 20-40 min; including one break after the fourth game. During the task completion the child will receive visual feedback (in the computer screen) about the number of shots already performed, time passed, and their ongoing performance (amount of sunk ships. After finishing the interview an archive file will be created for each participant containing the data coming from the computer game Battleship.
The Battleship: The game will attempt to discover four ships of different lengths stored as "battleships". You need to choose a frame to make a move. In any move a warning appears saying that he "missed" a ship, or "found" the ship. The total number of movements for each game played is saved to the computer. Then, for each game, a graph will be created to show the player's motion model. Each player has a different movement pattern.

Diagnosis / Prognosis
Comparator / control treatment
In the control group, 18 healthy children between the ages of 5 and 12 who are admitted to the Pediatric Outpatient Clinic and do not have the acute or chronic active disease will be included. The same protocol will be applied to the control group.
Control group
Active

Outcomes
Primary outcome [1] 319607 0
The Primary Outcome Measures of attention are the Total number of shots performed to solve the problem, their (x,y) coordinates and time between shots.
i A graph will be generated with the sequence of (x,y) coordinates of each shot fired to solve the problem;
ii Multifractal and Lacunarity spectrum along with other geometrical measures (biomarkers) will be estimated from the resulting graph.
Timepoint [1] 319607 0

Secondary outcome [1] 368846 0
Result of ADHD diagnostic coming from: Conners 3rd edition and DSM-IV-TR diagnostic interview.
Timepoint [1] 368846 0

Statistical methods / analysis
Conners' ADHD Rating Scale scores will be calculated for patients and the scores will be compared according to age and gender; t test or ANOVA test will be applied. When comparing scale scores, Pearson Correlation analysis will be applied to normal distributed data according to normality test, Spearman Correlation analysis will be applied to non-normally distributed data. By comparing the movement models obtained from the game of both groups, the difference between them will be investigated and the predictors of ADHD diagnosis will be determined.
Fractal analysis allows the mathematical expression of irregular and complex states. In this study, the spatiotemporal data obtained from the participants' movements during the play will be interpreted with the help of fractal analysis and the game will be investigated to predict ADHD diagnosis.
