A structural model of the test for creative thinking-drawing production (TCT-DP) in adults - revised

The Test for Creative Thinking-Drawing Production (TCT-DP, Urban & Jellen, 1996) is one of the best instruments for the creative potential assessment, which has been considered a crucial dimension in the organizational context. Considering its factorial structure, most studies have been limited using an exploratory approach. This research aims to assess the factorial structure of the TCT-DP (Form A) for a Portuguese adult sample, with a total of 620 workers, revisiting the results obtained in a study of Almeida, Ibérico Nogueira and Lima (2018). Two studies were performed. In Study 1, an exploratory factor analysis (EFA) was performed to assess the factorial structure of the TCT-DP. Take part in this study three hundred two individuals from Portugal, most of them were women (55,6%) and had an undergrad degree (74,8%), with age range from 18 to 86years (M = 41.1, SD = 10.7). In Study 2, there were three hundred eighteen individuals from Portugal, most of them were women (56,6%) and had an undergrad degree (79,9%), with age range from 19 to 70 years (M= 40.6, SD = 10.1). We perform a confirmatory factor analyses aiming to replicate the factorial solution identified in Study 1. The two-factor solution (F1- Adaptiveness; F2- Innovativeness) proposed in Study 1 had acceptable to marginal fit indices: 2 = 127,8, df = 34,2/df = 3.76, GFI = .93, CFI = .83, RMSEA = .093, CI 90% [.076, .0111], ECVI = 0.54. As in the study of 2018, two factors, Adaptiveness and Innovativeness, emerged and are composed by the same items, which led us, in the discussion, to a reflection about the parental practices features. Our model, already calledTTT - Two Tracks of Thought, highlights the importance of both non-conventional and conventional thinking for the creative process.
