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.
【摘要】 目的 考察青少年体像烦恼的注意偏向, 为制定青少年心理健康教育发展策略提供实证帮助。 方法 随机选取 琼海市某初级中学61名青少年学生为研究对象, 分为体像烦恼组30名和无体像烦恼组31名, 采用2(体像烦恼者、无体像 烦恼者)×2(髙吸引力体像图片、低吸引力体像图片)的混合设计进行点探测实验, 测量被试对探测点的反应时, 考察反应 时偏向指数和注意脱离指数2个行为数据。 结果 青少年反应时偏向分数组别主效应有统计学意义( F = 175.64, P<0.05), 体像烦恼者的反应时偏向分数[图片呈现髙一中(39.39±15.13)ms:图片呈现低一中(28.40±26.07) ms ]大于无体像 烦恼者[(−18.31±16.57)(−17.83±9.19)ms], 被试对体像图片存在注意维持;注意脱离指数组别主效应有统计学意义( F = 38.21, P<0.05), 体像烦恼者的注意脱离指数[髙体质图注意脱离指数(18.42±13.92)ms;低体质图注意脱离指数(15.84± 19.62)ms]大于无体像烦恼者[(−4.05±13.49)(−1.83±9.72)ms], 被试对体像图片存在注意脱离困难。 结论 青少年体像 烦恼者对体像图片存在注意偏向, 且存在注意警觉一维持模式。
