Dataset assessing three samples of French university students to 5 personality tests: IPO, PDQ-4+, PANAS, AQ and HADS.

This dataset provides the results of three samples of French university students to 5 personality tests: IPO, PDQ-4+, PANAS, AQ and HADS. These three studies were approved by the research ethics committee of Angers University (November 2021). Data were collected from November 26, 2021 to February 19, 2022 for Studies 1 and 2. Data collection for Study 3 ended on September 31, 2022. 1) The first part of this dataset (Study 1) comprise 602 first- and second-year psychology students (University of Angers, France): 112 men, 486 women, and 4 participants of unspecified gender (Mean age = 19.40 years / SD = 1.95). This first part of dataset is composed of two separate samples: 269 first-year students (Sample 1 = Study 1 Sample 1.xlsx) and 333 second-year (Sample 2 = Study 1 Sample 2.xlsx). It gives the scores obtained by this sample of students to the French translation of the Inventory of Personality Organization (Kernberg). In IPO, the level of personality organization is established by assessing three main components of personality, namely Primitive psychological Defenses (PD = 16 items), Identity Diffusion (ID = 20 items), and Reality Testing (RT= 21 items). Personality disorders manifest themselves in high levels of one or more of these three dimensions (scales). This data set gives the results obtained by this group of students on these 57 items. The second part of this dataset (Study 2 = Study 2.xlsx) is consisted of 305 students from different departments (Arts and humanities) at the University of Angers. It is composed of 63 men and 242 women, with a mean age of 19.83 years (SD = 2.12). It offers the results of this sample to the three scales (PD/ID/RT) of the French translation of the IPO and to the French versions of the following tests: Personality Diagnostic Questionnaire-4+ (PDQ-4+), Positive and Negative Affect Schedule (PANAS), Aggression Questionnaire (AQ), and Hospital Anxiety and Depression Scale (HADS). Studies 1 and 2 were used to develop and validate the French version of the IPO in 40 items and 2 scales (PD-ID/RT): the IPO-fr. In the third part (= Study 3), respondents are 182 first- and second-year students from the Department of Psychology and 425 first- and second-year students from the Departments of History, Language Studies and Physical and Social Geography (Mage = 19.38, SD = 1.93). Study 3 contains (1) Responses from 607 French young adults to each item of the IPO-fr, (2) Responses obtained by the same 607 respondents to the French PDQ-4+ (self-report questionnaire and Clinical significance scale), and (3) Basic demographic information (gender and age) collected for all respondents. For the IPO-fr, scores on the PD/ID and RT scales were calculated by summing participants' scores on the items in each scale. The total score consists of the sum of participants' scores on the PD/ID and RT scales. A codebook containing the French version of the PDQ-4+ and the IPO-fr is included in this dataset.
