RESUMO
Objective To explore the transtheoretical model(TTM) intervention effect on reducing communicative anxiety in obese children to improve their psychological status.Methods A quasi-experimental research was conducted in a randomly selected boarding school of Changsha.Seventy-three obese students with an average age of (9.60 ± 1.22) among Grade 3 to Grade 6 were included.After being enrolled in the intervention,all participants received the first assessment,including the stage-change scale and the communicative anxiety scale for children(including 2 parts:denial scary,social withdraw and annoyance).According to the baseline data,different intervention measures based on TTM were applied to different students.Follow-up assessments were collected respectively after 1-month and 6-month intervention,respectively.Repeated measurement data analysis of variance and follow-up Bonferroni test was conducted to assess intervention effect.Results Repeated measurement data ANOVA showed that after intervention,both scores of denial scary and social withdraw and annoyance significantly reduced(P ＜0.001),while body mass index had no significant difference (P ＞ 0.05).Follow-up Bonferroni test showed after 1 month intervention,social anxiety scores had no significant difference (P ＞ 0.05),while 6-month after the scores were significant different compared with pre-intervention and 1-month intervention(all P ＜0.05).Conclusions TTM intervention may effectively decrease communicative anxiety of obese children.Whether it can make BMI reduced significantly needs more research.
