Research on everyday creativity—the “little c” creative activities people do in their everyday lives—commonly uses self-report scales to assess people’s engagement in different activities. The present research presents a detailed psychometric analysis of the Biographical Inventory of Creative Behaviors (BICB), a 34-item yes/no checklist of common creative activities that has become one of the most popular self-report measures of everyday creative behaviors. Based on a sample of 2,359 adults, the reliability, dimensionality, item fit, item difficulty, and test information were evaluated from a Rasch model perspective. Overall, the BICB shows good evidence for score reliability and appears essentially unidimensional; a small cluster of misfitting and locally dependent items were flagged for impairing unidimensionality. The items’ difficulty level was generally moderate and suitable for the scale’s intended populations and purposes. Differential item functioning (DIF) based on gender and age, estimated via Rasch tree recursive partitioning methods, found notable gender-based DIF (generally reflecting culturally gendered qualities of some creative activities) but little age-based DIF. Taken together, the BICB has many psychometric strengths. Some opportunities for future scale refinement are discussed.

日常创造力研究是人们日常生活中进行的“小c”创造活动，通常使用自我报告量表来评估人们参与不同活动的程度。本研究对创意行为传记清单（BICB）进行了详细的心理计量学分析，是一项34项是/否常见创意活动的清单，已成为日常创意行为中最受欢迎的自我报告指标之一。基于2359名成年人的样本，从Rasch模型的角度评估了可靠性，尺寸，项目适合度，项目难度和测试信息。总体而言，BICB显示出评分可靠性的良好证据，并且基本上是一维的。一小撮不合身和当地依赖的物品被标记为削弱一维性。这些项目的难度级别通常是中等的，适合于量表的预期人群和目的。基于性别和年龄的差异项功能（DIF），通过Rasch树递归分区方法进行估算，发现了显着的基于性别的DIF（通常反映了某些创意活动的文化性别特质），但基于年龄的DIF却很少。综上所述，BICB具有许多心理方面的优势。讨论了将来扩大规模的一些机会。
