Data of personality traits and safety attitudes in aviation maintenance
Description
The study utilised a questionnaire divided into three sections: Demographic Information, Personality Traits, and Safety Attitudes. 1. Seven demographic questions were provided: Gender, Total length of work experience, Length of work experience in a current role, Type of license/authorisation, Maintenance approval, Supervisor/Team leader, and, current work area 2. The Big Five Inventory was used to assess personality traits. The Personality Traits section included 44 questions covering Extraversion (8 questions), Agreeableness (9 questions), Conscientiousness (9 questions), Neuroticism (8 questions), and Openness (10 questions). 3. The Safety Attitudes section comprised 34 questions categorised into four sub-groups: Understanding of job roles, Teamwork in Emergencies, Overall Importance of Effective Teamwork and Communication, and the Importance of Clear Communication within aviation Team. Both personality traits and safety attitudes were assessed using a 5-point Likert scale (1: Disagree Strongly, 2: Disagree a Little, 3: Neither Agree nor Disagree, 4: Agree a Little, 5: Agree Strongly).

Data analysis was conducted through two different methods: SPSS 1. Personality traits and safety attitudes questionnaires include reverse-scored items, which are indicated by an "R" in their names (e.g., PS_Agreeableness_2R, SA_16R_teamwork_and_communication). Before conducting the analysis, it is necessary to reverse-code these items. 2. The mean scores of personality traits and safety attitudes were calculated and used for analysis. 3. The dataset consists of two worksheets: The first sheet displays variable labels in numerical format (e.g., '1'). The second sheet provides the corresponding string format (e.g., 'Female'). 4. Among the demographic items, the current work area question allowed multiple responses. 4. Analysis Methods: 4.1. Demographic items and safety attitudes: A normality test (i.e. Kolmogorov–Smirnov test, Shaprio-Wilk test) was first conducted, and based on the results, either parametric tests (ANOVA, Independent t-test) or non-parametric tests (Kruskal-Wallis H test, Mann-Whitney U test) were applied. 4.2. Personality traits and safety attitudes: Spearman's rho correlation test was conducted to assess the relationship between the five personality traits and safety attitudes. 4.3. Robust regression analysis: A robust regression analysis was conducted to examine whether personality traits explain variance in safety attitudes beyond the influence of demographic factors, while accounting for outliers and violations of regression assumptions (e.g., normality of residuals). The analysis followed a two-step approach: first, demographic variables were entered into the model, followed by personality traits to assess their additional contribution.
