Brief summary

Survival rates of children with severe congenital heart disease (CHD) have increased with ongoing medical progress over the past decades. However, many children with CHD face academic challenges during adolescence, which are associated with executive dysfunction. Executive functions (EF), higher-order cognitive processes allowing goal-directed behavior, can be particularly affected in children with CHD. To improve EF in affected children, a specific EF intervention has been developed. The intervention lasts a total of 8 weeks and is structured in 3 modules. The first module consists of a weekly strategy training in which problems resulting from executive dysfunction are addressed. Online games form the second module. These are games implemented online to promote EF through play. The third module is also based on games: The families receive several board games to play together at home. This third module is voluntary. This intervention is tested on its feasibility. As the intervention was built in a patient centered manner, we expect it to be feasible, showing in a high adherence rate and satisfaction.

Design outcomes

Primary

MeasureTime frameDescription
Balloon Analogue Risk Task (BART)10 minutesIn the experiment, participants are presented with a balloon. The participant is prompted to inflate the balloon using the Right Arrow key. After successfully inflating the balloon by 1 unit, the participant receives five points. The more the participant inflates the balloon, the more points they receive. E-Prime randomly selects a number between 1 and 100 for each trial representing the total number of inflated units before the balloon bursts. If the participant inflates the balloon too much, it pops and no points are given. Participants also have the choice to press the Left Arrow to advance the trial while keeping their points. There is one practice trial and 5 critical trials.
Behavior Rating Inventory of Executive Function (BRIEF)15 minutesThe BRIEF assesses Executive Functions Behavior in everyday life. The results will be be transformed into a categorical variable with results \> 1 SD defined as abnormal (T-scale \>= 60).
Color word Interference Task (D-KEFS)5 minutesThe D-KEFS Color-Word Interference Test is based on the classic Stroop task, which is primarily used to assess the ability to inhibit verbal responses (inhibition).
Go/NoGo Test battery for attention testing (TAP)5 minutesIn this test, 2 implementation forms with different stimulus material are offered. In the 1st condition, reaction times and errors are measured in a simple Go/Nogo condition with two stimuli (+ and x: 2 stimuli, one critical), in the 2nd more complex condition with 5 squares with different filling patterns, 2 of which are defined as critical (5 stimuli, 2 critical).
Trail-Making-Test (D-KEFS)5 minutesThe D-KEFS Trail Making Test is a revision and extension of the classic alternating number and letter matching task, which is known as a proven instrument for assessing cognitive flexibility. With the help of four additional conditions, the basic abilities of visual scanning, connecting numbers and letters, and motor speed can be assessed. This results in a differentiated overall picture of the interaction of different basic and higher cognitive abilities.
Number-Letter-sequencing (WISC-V)10 minutesIn number repeating, the subject is read a sequence of numbers and asked to repeat them in the same order (number repeating - forwards), in reverse order (number repeating - backwards) or in ascending order (number repeating - sequential).
Tower Task from the (D-KEFS)15 minutesThe D-KEFS Tower Test is a revision of classic tower tasks in which discs are to be restacked with the help of three rods in such a way that given tower templates are replicated, while observing certain rules. Nine standardised tasks covering a difficulty spectrum from very easy to very difficult are designed to avoid floor and ceiling effects. The test measures, among other things, spatial planning ability, rule learning, inhibition of impulsive or perseverative response behaviour, as well as the development and maintenance of mental attitudes.
Fun and cognitive demand5 minutesSubjective Feasibility, Fun and cognitive demand: the two questions How fun was the training? and How much did you use your brain are answered on a 5-point Likert scale (1 referring to not at all and 5 referring to very much). Both questions are treated as ordinal scaled and median and interquartile range will be reported.
Children's Feeling Scale5 minutesSubjective Feasibility, Affect 11-point single item bipolar scale (-5 referring to very bad and 5 referring to very good). The Hulley feeling scale is treated as ordinal scaled and median and interquartile range will be reported.
Acceptance and Feasibility scale5 minutes4-point Likert scale (1 referring to don't agree at all and 4 referring to fully agree). Treated as ordinal scaled and median and interquartile range, as well as percentages of persons who answered the items with 3 or 4, will be reported.
