This study examined personality expression, impression formation, and the consensus and accuracy of zero-acquaintance personality judgments that were based on people's Instagram accounts.
Self- and informant reports of the Big Five personality traits, self-esteem, and narcissism were collected for 102 Instagram users. Screenshots were taken of Instagram users' profiles, including up to the 102 latest available Instagram posts. A number of Instagram cues were objectively retrieved, counted, and rated by independent trained cue coders from the screenshots. 100 unacquainted observers then judged the Big Five traits, self-esteem, and narcissism on the basis of Instagram screenshots only.
We identified Instagram account characteristics that were associated with users' personality traits (measured with self-reports, informant reports, and self-informant composites) and observers' zero-acquaintance personality judgments. Personality judgments that were based on Instagram accounts demonstrated consensus and significantly converged with Instagram users' Big Five traits, self-esteem, and narcissism across all three personality criteria. Averaged-observer accuracy correlations for self-informant composite scores ranged from r = .44 (p < .001) for extraversion to r = .25 (p = .013) for conscientiousness.
Our findings provide insight into cue processes of online self-portrayal and impression formation on Instagram and the level of zero-acquaintance accuracy.
本研究考察了基于人们Instagram账户的个性表达、印象形成以及零熟人个性判断的共识和准确性。
收集了102名Instagram用户的大五人格特质、自尊和自恋的自我报告和知情者报告。截取了Instagram用户资料的屏幕截图，包括多达102条最新的Instagram帖子。由独立训练的线索编码员从屏幕截图中客观地检索、统计和评估了一些Instagram线索。然后，100名互不相识的观察者仅根据Instagram屏幕截图对大五人格特质、自尊和自恋进行判断。
我们确定了与用户个性特质（通过自我报告、知情者报告和自我-知情者综合测量）以及观察者的零熟人个性判断相关的Instagram账户特征。基于Instagram账户的个性判断显示出共识，并且在所有三个个性标准上与Instagram用户的大五人格特质、自尊和自恋显著趋同。自我-知情者综合得分的平均观察者准确性相关性范围从外向性的r = 0.44（p < 0.001）到尽责性的r = 0.25（p = 0.013）。
我们的研究结果为Instagram上的在线自我呈现和印象形成的线索过程以及零熟人准确性水平提供了见解。
