To investigate the role of personality factors and attentional biases towards emotional faces, in establishing concurrent and prospective risk for mental disorder diagnosis in adolescence.
Data were obtained as part of the IMAGEN study, conducted across 8 European sites, with a community sample of 2257 adolescents. At 14 years, participants completed an emotional variant of the dot-probe task, as well two personality measures, namely the Substance Use Risk Profile Scale and the revised NEO Personality Inventory. At 14 and 16 years, participants and their parents were interviewed to determine symptoms of mental disorders.
Personality traits were general and specific risk indicators for mental disorders at 14 years. Increased specificity was obtained when investigating the likelihood of mental disorders over a 2-year period, with the Substance Use Risk Profile Scale showing incremental validity over the NEO Personality Inventory. Attentional biases to emotional faces did not characterise or predict mental disorders examined in the current sample.
Personality traits can indicate concurrent and prospective risk for mental disorders in a community youth sample, and identify at-risk youth beyond the impact of baseline symptoms. This study does not support the hypothesis that attentional biases mediate the relationship between personality and psychopathology in a community sample. Task and sample characteristics that contribute to differing results among studies are discussed.
探讨人格因素及对情绪面孔的注意偏向在确定青少年精神障碍诊断的共时性和前瞻性风险中的作用。
数据作为IMAGEN研究的一部分获得，该研究在8个欧洲地点开展，样本为2257名青少年的社区样本。14岁时，参与者完成了点探测任务的情绪变体，以及两项人格测量，即物质使用风险概况量表和修订的大五人格量表。在14岁和16岁时，对参与者及其父母进行访谈以确定精神障碍症状。
人格特质是14岁时精神障碍的一般和特定风险指标。在调查两年内精神障碍的可能性时，特异性有所提高，物质使用风险概况量表显示出比大五人格量表更高的效度。对情绪面孔的注意偏向并未表征或预测当前样本中所研究的精神障碍。
人格特质可表明社区青年样本中精神障碍的共时性和前瞻性风险，并识别出不受基线症状影响的高危青年。本研究不支持注意偏向介导社区样本中人格与精神病理学之间关系的假设。文中讨论了导致不同研究结果存在差异的任务和样本特征。
