An assessment of personality traits based on photos on Inastagram

This research is focused on the accuracy assessment of personality traits based on visual content (photos) on the Instagram social network. The research sample consisted of a group of participants who provided voluntary their Instagram profiles for assessment (N = 4) and a group of independent assessors (N = 342). The accuracy of the assessment was based on the assessors' consensus and the degree of agreement between assessors and the accuracy criterion. The accuracy criterion is based on a self-assessment and an assessment by another close person selected by the profile owner. The highest assessor consensus was for extraversion, and the most accurately assessed traits were neuroticism and agreeableness – with women being more accurate in their assessments. Despite expectations, however, the assessors were most accurate in evaluating neuroticism and agreeableness. The data consists of four datasets and one file of data description. Dataset A: Self-reports of Instagram profile owners. Four profile owners completed a questionnaire consisting of items on demographic data and user behavior on Instagram and personality (Ten Item Personality Inventory TIPI). Dataset B: Assessment by a close person. The assessment by a close person allowed us to create a correctness criterion based on a self-report assessment and an assessment by another person. Dataset C: Assessment of four Instagram profile owners by independent assessors (N = 342). In this data set are differences between correctness criterion and average of assessment of BF personality traits (overestimation and underestimation of traits by independent assessors). Dataset D: Correctness criterion. The calculation of average value between self-report and other report (close person). The file Variables description contents exact description of every variable in all four datasets.本研究聚焦于基于Instagram社交平台视觉内容（照片）开展的人格特质评估准确性验证。研究样本包含两组：其一为自愿提供其Instagram个人主页用于评估的参与者（N=4），其二为独立评估者群体（N=342）。评估准确性以评估者的共识程度，以及评估者与准确性基准之间的契合度为衡量依据。准确性基准基于主页所有者的自评结果，以及其选定的其他亲密他人的评估结果构建。研究结果显示，外向性维度的评估者共识度最高，而神经质与宜人性维度的评估准确性最优，且女性评估者的评估表现更为精准。然而与预期相悖的是，评估者对神经质与宜人性维度的评估最为准确。本研究数据集包含四份子数据集与一份数据说明文件：子数据集A：Instagram主页所有者自评数据。共4名主页所有者完成了涵盖人口统计学信息、Instagram用户行为及人格特质的问卷，问卷采用十项人格量表（Ten Item Personality Inventory, TIPI）进行人格测评。子数据集B：亲密他人评估数据。该类评估数据可结合自评结果与他人评估结果，构建评估准确性基准。子数据集C：342名独立评估者对4名Instagram主页所有者的人格评估数据。该数据集包含准确性基准与独立评估者的大五人格（Big Five, BF）特质平均评分之间的差值，即独立评估者对各特质的高估与低估情况。子数据集D：准确性基准数据。即自评结果与亲密他人评估结果的平均值。变量说明文件详细阐释了四份子数据集内所有变量的具体定义与说明。
