Objective: To examine attentional bias in relation to body image problems among adolescents. Methods: A total of 61 adolescent students from a junior high school in Qionghai City were selected as the research objects and divided into body image problems group( n =30) and non body image problems group( n =31). A 2×2 mixed design was employed to examine adolescents with body image problems and adolescents with no body image problems, as well as body images depicting high and low attractiveness. Point detection experiments were conducted to measure the participants responses to the detection point. Two types of behavioral data were used including the reaction time bias index and the attentional disengagement index. Results: A significant difference was observed in the group main effect of the reaction time bias score ( F =175.64, P <0.05). The response bias scores of adolescents with body image problems [The picture was high medium(39.39±15.13)ms;The picture is low medium(28.40±26.07)ms] were greater than those of adolescents with no body image concerns [(-18.31±16.57)(-17.83±9.19)ms], which indicated that the subject had a body image picture attention maintenance; the main effect of the attentional detachment index group was significantly different ( F =38.21, P <0.05). The attentional detachment indexwas higher among adolescents with a disordered attentional body image [Attention disengagement index of high volume image(18.42±13.95)ms;Attention disengagement index of low body image(15.84±19.62)ms] than among those who had no body image concerns [(-4.05±13.49)(-1.83±9.72)ms], indicating that the subject has a body image. When attending to the images, these participants had difficulties in disengaging their attention. Conclusion Adolescents with body image problems show an attentional bias towards body image pictures, and the results indicated an attentional alert maintenance mode.
