Cognitive factors associated with depression and anxiety in adolescents: A two-year longitudinal study.

: To examine the roles of anxiety sensitivity and attentional bias in the development of anxiety and depression symptoms among adolescents. : 214 grade 7 to grade 10 Hong Kong Chinese students completed a package of psychometric inventories to measure levels of anxiety sensitivity, selective attentional processing, and anxiety and depressive symptoms in 2016 and then again in 2017. Girls, when compared with boys, exhibited more anxiety symptoms and anxiety sensitivity in 2016. They also reported a significant increase in mean depression level from 2016 to 2017. Regression analyses revealed that the physical-concerns dimension of anxiety sensitivity, positive attentional bias, and to a lesser extent negative attentional bias were related to the development of both anxiety and depression symptoms one year later. Fear of mental incapacity could predict depression one year later but not anxiety symptoms. : Intervention through anxiety sensitivity training to reduce somatic concerns and attentional bias modification to increase habitual attention to positive stimuli and to disengage from negative stimuli can reduce anxiety and depression symptoms among high school students.
