NCT04831229

Brief Summary

Introduction: In the last decade the prevalence of the use of interactive media (smartphone, tablet) by children has grown worldwide. However, it is not yet known what its effects are on the development of children in early childhood and whether the form of use (passive or active) influences this practice. In view of this, the present study aims to assess, through a randomized clinical trial (RCT), whether the form of use of mobile interactive media interferes with the Methods: The investigators propose an RCT with 64 children aged 24 to 36 months and their parents. Initially, identification, information about the child and history of media use will be carried out through the Questionnaire on the Use of Interactive Media, economic classification (Brazil Economic Classification Criterion). Then, the quality of the school environment (Infant / Toddler Environment Rating Scale) will be observed and, finally, measures of cognitive, motor and language development through the Bayley III Scale and Auditory Vocabulary Test. For follow-up purposes, parents will be asked to complete the Daily Record Board. Children will be randomly randomized into two groups: Active Interactive Media Group: children will use the media actively (games) and Passive Interactive Media Group: children will use the media passively (content viewing). Both groups will participate in the intervention for 30 minutes, three times a week, for 16 weeks. After this period, children will be reassessed for cognitive, language and fine motor development, receptive vocabulary and analysis of the Daily Record Board. Discussion: The results can provide (1) information on which form of use has the most benefits for children (2) guide parents, educators and health professionals on how to offer interactive media. Trial registration: This clinical trial was submitted to and approved by the Research Ethics Committee of Universidade Federal dos Vales do Jequitinhonha e Mucuri (CAAE 29490420.9.0000.5108). The complete protocol was registered in the Clinical Trials REBEC ( https://ensaiosclinicos.gov.br) under number RBR-8j3tzw Keywords: Child Development, Tablet, Interactive Tutorial, Clinical Trial.

Outcome Measures

Primary Outcomes (6)

  • Cognitive development was chosen as a primary outcome measure, as interactive media it is known to be affected by interactive media.

    To assess development in the cognitive domain, the Bayley III scale will be used, which assesses children from one to 42 months of age. The total score is converted into a balanced score and / or composed using tables provided in the manual. The composite score is based on age standards, where the child is rated from 40 to 160. The average score is 100, with ± 15 points standard deviation. This score will classify children into ranges: much higher (\> 130 points), higher (between 129 to 120 points), above average (119 to 110 points), average (109 to 90 points), below average (89 at 80 points), borderline (79 to 70 points) and extremely low (69 or less points).

    Tests performed before the intervention

  • Motor development was chosen as a primary outcome measure, as interactive media it is known to be affected by interactive media.

    To assess development in the Motor domain, the Bayley III scale will be used, which assesses children from one to 42 months of age. The total score is converted into a balanced score and / or composed using tables provided in the manual. The composite score is based on age standards, where the child is rated from 40 to 160. The average score is 100, with ± 15 points standard deviation. This score will classify children into ranges: much higher (\> 130 points), higher (between 129 to 120 points), above average (119 to 110 points), average (109 to 90 points), below average (89 at 80 points), borderline (79 to 70 points) and extremely low (69 or less points).

    Tests performed before the intervention

  • Language development was chosen as a primary outcome measure.

    The assess the receptive vocabulary of children, a validated instrument, the Auditory Vocabulary Test (TVAud - A33o), will also be used.According to age and score, children will be classified as follows: 2 year old children: medium level (17 and 28 points); low (12 and 16 points), very low (6 and 11 points) and high (29 and 33 points). 3-year-old children: medium level (24 and 31 points), low (21 and 23 points), very low (17 and 20 points) and high (31 and 33 points).

    Tests performed before the intervention

  • Change Cognitive development was chosen as a primary outcome measure, as interactive media it is known to be affected by interactive media.

    To assess development in cognitive, motor and linguistic domains, the Bayley III scale will be used, which assesses children from one to 42 months of age in order to identify developmental delay. The score can be converted into balanced scores and / or composed through the use of tables provided in the manual. The approximate duration of the scale application is 50 minutes. The Bayley III test is the gold standard for development assessment and validated for the Brazilian population.

Study Arms (2)

Active Interactive Media Group

ACTIVE COMPARATOR

AIMG children will perform active activities on the interactive tablet media. The games and applications that will be used during this intervention were selected through a search in the online application store compatible with the tablet used during the intervention (Google Play). The search term used was "games for children aged 2 to 3 years" and they were analyzed for the following criteria: (1) interactivity: critical thinking, active participation, decision making; (2) learning: activities that stimulate cognitive development, fine motor, receptive language, expressive and social-emotional language (see table 1 to view activities); (3) suitability: age, period of development, multiple domains and (4) results: challenging activity, not frustrating, providing feedback

Other: Children will perform activities on interactive tabletOther: Children will perform passive on interactive tablet

Passive Interactive Media Group

ACTIVE COMPARATOR

PIMG children will go to the intervention room where they will use interactive tablet media in passive activities, such as: watching videos and children's stories that they often watch at home. This survey will be possible thanks to the questionnaire on the Use of Interactive Media where parents will list which drawings, stories and videos children use to watch.

Other: Children will perform activities on interactive tabletOther: Children will perform passive on interactive tablet

Interventions

AIMG will actively perform activities with user interaction with the equipment through touch or verbal response. Both groups will have a total of 48 intervention sessions.

Also known as: active interactive tablet
Active Interactive Media GroupPassive Interactive Media Group

The PIMG is just a spectator, having contact with the equipment only when switching on / off, "play" / pause ". Both groups will have a total of 48 intervention sessions.

Will share

Personal, demographic and economic data will be collected only once, before interventions start. Each child will be identified by code using the initial CMEI of origin and ascending order of numbering. This identification will be carried out by a person who will not participate in any phase of the research and will be stored in a safe place. The data generated after evaluation will be analyzed and displayed in graphs, tables or images. They will be saved and stored on the computers of the main researchers, password protected, and on online platforms and will be accessed through common software. Data that is available on paper will be kept in a key office. It is important to note that all data will be treated confidentially. The data will be preserved for at least five years after the end of the research by the responsible physiotherapist (SG), who will be closely supervised by the supervising professor (JS)
