Short-term Efficacy of Reducing Screen-based Media Use

2019-09-26 05:42:35 | BioPortfolio


The purpose of this randomized controlled trial is to investigate the short-term efficacy of reducing recreational screen-based media use on physical activity patterns, sleep, physiological stress in families at least one child between 6-10 years of age.


Today screen-based media devices are almost unavoidable in our everyday lives. The media landscape has changed markedly during the past decade with some of the main aspects being the introduction of new portable devices, social networks, and online streaming services. The current experimental evidence on the efficacy of reducing todays screen-based media use in free-living is scarce.

This randomized controlled trial will be carried out based on the experience from a recently conducted pilot study, which was a 2-arm randomized non-controlled trial. The purposes of the pilot study were to explore the feasibility of our recruitment protocol, 7-day measurement protocol and the degree of compliance to the intervention components; namely a heavy restriction in recreational screen time for a 2-week period, either timed (no screen after 18 pm) or time restricted (≤ 3 hours/week/person).

In the current trial, only the time restricted protocol will be included, compared to a control group. To investigate the short-term efficacy of the intervention, the participants will go through a 7-day measurement protocol at baseline and again, during the final week of the intervention period (follow-up).

We will recruit families with at least one child between 6-10 years of age. A randomly selected adult from each household will be invited to answer a questionnaire, also including an invitation regarding participation in the current randomized controlled trial. Invitations will be sent to the adults' digital mailbox (e-boks), which is an online solution where one can receive mail from e.g. Danish public authorities. Based on the answers in the survey a preliminary screening for eligibility will be conducted (see section on inclusion/exclusion criteria). Families who fulfill specific criteria in the survey and further criteria assessed during a phone conversation will be invited to participate in this randomized controlled trial. Families who wish to participate will, after completion of the baseline protocol, will be randomized to either the intervention group or the control group (see section on arms and interventions).

The intervention (reducing recreational screen-based media use) was designed using the core major and minor elements of Albert Bandura's Social Cognitive Theory; namely, based on the idea of reciprocal determinism of an individual's environment, personal factors and behavior. The intervention includes i) a preparation document and meeting with the parents with the purpose of planning the course of the intervention and prepare the parents to set goals and self-regulate; ii) handing over the families portable screen devices when possible with an alternative mobile phone in exchange, which can be solely used for calls and text messages, will be afforded to the participants; iii) installing monitor software on all computers (stationary and laptops) and tablets and smartphone if these could not be given up, and connect a monitor device to all televisions in each household; iv) using "intervention reminders" (social cues), which will be placed beside stationary screen-based media devices and at central positions in the household such as the dining table.

Medical and Biotech [MESH] Definitions

Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.

A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.
