Effect of electronic time monitors on children's television watching: pilot trial of a home-based intervention.
OBJECTIVES This pilot study evaluated the feasibility ( recruitment , retention , and acceptability ) and preliminary efficacy of a six-week home-based electronic time monitor intervention on New Zeal and children 's television watching in 2008 . METHODS Twenty-nine children aged 9 to 12 years who watched more than 20 h of television per week ( 62 % male , mean age 10.4 years ) were r and omised to either the intervention or the control group . The intervention group received an electronic TV time monitor for 6 weeks and advice to restrict TV watching to 1 h per day or less . The control group was given verbal advice to restrict TV watching . RESULTS Participant retention at 6 weeks was 93 % . Semi-structured interviews with intervention families confirmed moderate acceptability of TV time monitors and several perceived benefits including better awareness of household TV viewing and improved time planning . Drawbacks reported included disruption to parents ' TV watching and increased sibling conflict . Time spent watching television decreased by 4.2 h ( mean change [ SD ] : -254 [ 536 ] min ) per week in the intervention group compared with no change in the control group ( -3 [ 241 ] min ) , but the difference between groups was not statistically significant , p=0.77 . Both groups reported decreases in energy intake from snacks and total screen time and increases in physical activity measured by pedometer and between-group differences were not statistically significant . CONCLUSIONS Electronic TV time monitors are feasible to use for home-based TV watching interventions although acceptability varies between families . Preliminary findings from this pilot suggest that such devices have potential to decrease children 's TV watching but a larger trial is needed to confirm effectiveness . Future research should be family-orientated ; take account of other screen time activities ; and employ TV time monitors as just one of a range of strategies to decrease sedentary behaviour
