Feasibility trial evaluation of a physical activity and screen-viewing course for parents of 6 to 8 year-old children: Teamplay
Background Many children spend too much time screen-viewing ( watching TV , surfing the internet and playing video games ) and do not meet physical activity ( PA ) guidelines . Parents are important influences on children ’s PA and screen-viewing ( SV ) . There is a shortage of parent-focused interventions to change children ’s PA and SV . Methods Teamplay was a two arm individualized r and omized controlled feasibility trial . Participants were parents of 6–8 year old children . Intervention participants were invited to attend an eight week parenting program with each session lasting 2 hours . Children and parents wore an accelerometer for seven days and minutes of moderate-to-vigorous intensity PA ( MVPA )  were derived . Parents were also asked to report the average number of hours per day that both they and the target child spent watching TV . Measures were assessed at baseline ( time 0 ) at the end of the intervention ( week 8) and 2 months after the intervention had ended ( week 16 ) . Results There were 75 participants who provided consent and were r and omized but 27 participants withdrew post-r and omization . Children in the intervention group engaged in 2.6 fewer minutes of weekday MVPA  at Time 1 but engaged in 11 more minutes of weekend MVPA . At Time 1 the intervention parents engaged in 9 more minutes of  weekday MVPA  and 13 more minutes of weekend MVPA  . The proportion of children in the intervention group watching ≥ 2 hours per day of TV on weekend days decreased after the intervention ( time 0 = 76 % , time 1 = 39 % , time 2 = 50 % ) , while the control group proportion increased slightly ( 79 % , 86 % and 87 % ) . Parental weekday TV watching decreased in both groups . In post- study interviews many mothers reported problems associated with wearing the accelerometers . In terms of a future full-scale trial , a sample of between 80 and 340 families would be needed to detect a mean difference of 10-minutes of weekend MVPA . Conclusions Teamplay is a promising parenting program in an under- research ed area . The intervention was acceptable to parents , and all elements of the study protocol were successfully completed . Simple changes to the trial protocol could result in more complete data collection and study engagement
