Study summary

This randomized controlled trial aims to evaluate the effect of digital intelligence games on visual and cognitive performance in young individuals with intellectual disabilities. Participants aged 18-35 years receiving services from EÇADEM in Istanbul will be randomly assigned to either an intervention group receiving digital intelligence game training using the MentalUP application or a control group receiving routine services. Visual memory and cognitive performance will be assessed using the Benton Visual Retention Test and the Standardized Mini Mental Test at baseline, 3 months, 6 months, and 12 months. The study will investigate the short- and long-term effects of digital cognitive training on visual and cognitive functioning.

Read the detailed description

This study is designed as an experimental, parallel-group, repeated-measures randomized controlled trial. The study aims to examine the effects of digital intelligence games on the visual and cognitive performance of young individuals with intellectual disabilities.

Participants will be recruited from EÇADEM (Engelli Çocuklar Aile Destek Eğitim Merkezi) located in Sarıyer district of Istanbul. Participants meeting the inclusion criteria will be randomly assigned to intervention and control groups using stratified block randomization according to the level of intellectual disability (mild and moderate).

The intervention group will participate in structured digital intelligence game activities using the MentalUP platform, conducted twice weekly under the supervision of a clinical psychologist and an occupational therapist. The control group will receive routine services provided by the center without additional intervention.

Data will be collected at baseline and at 3-, 6-, and 12-month follow-ups using the Benton Visual Retention Test and the Standardized Mini Mental Test. The study will evaluate both short-term and long-term effects of the digital intervention.

The study protocol follows the CONSORT guidelines for randomized controlled trials.

Study arms

  • Experimental
    Digital Intelligence Game Intervention

    Participants will receive digital intelligence game training using the MentalUP platform under supervision of a clinical psychologist and occupational therapist. Sessions will be conducted twice weekly and include structured cognitive exercises targeting attention, memory, and problem-solving skills.

    Behavioral: MentalUP Digital Intelligence Game

  • No intervention
    Routine Care

    Participants will receive routine services provided by EÇADEM without additional digital cognitive training.

Interventions

  • BehavioralMentalUP Digital Intelligence Game

    MentalUP is a digital cognitive training platform designed to improve attention, memory, logical reasoning, and problem-solving abilities through adaptive intelligence games.

What researchers measure

Primary outcomes

  1. Change in visual memory performance

    Visual memory performance will be assessed using the Benton Visual Retention Test (BVRT). The BVRT evaluates visual perception, visual memory, and visuoconstructive abilities by asking participants to identify previously presented geometric figures. Scores range from 0 to 15, with higher scores indicating better visual memory performance.

    Time frame: Baseline, 3 months, 6 months, and 12 months

  2. Change in cognitive performance

    Cognitive performance will be evaluated using the Standardized Mini Mental Test (SMMT). The SMMT assesses orientation, attention, memory, language, and visuospatial abilities. Scores range from 0 to 30, with higher scores indicating better cognitive functioning.

    Time frame: Baseline, 3 months, 6 months, and 12 months after baseline.
