Introduction The Inventory of Academic Sources of Stress in Medical Education (IASSME) evaluates the presence and intensity of the main sources of academic stress for Portuguese Medicine students in five dimensions: Course demands/CD, Human demands/HD, Lifestyle/LS, Academic competition/AC, and Academic adjustment/AA. Objectives To further validate the ISSME using Confirmatory Factor Analysis and to analyze the psychometric properties of a new version including additional sources of stress. Methods Participants were 666 Portuguese medicine (82.6%) and dentistry (17.4%) students (81.8% girls); they answered an online survey including the ISSME and other validated questionnaires: Maslach Burnout Inventory – Students Survey (MBI-SS) and Depression Anxiety and Stress Scales (DASS). Results Confirmatory Factor Analysis showed that the second order model composed of five factors (the original structure by Loureiro et al. 2008), but excluding item 11 (loading=.371), presented good fit indexes (χ2/df=3.274; RMSEA=.0581, p<.001; CFI=.917; TLI=.904, GFI=.919). The Cronbach’s alfas were α=.897 for the total and from α=.669 (F2-HD) to α=.859 (F1-CD) for the dimensions. The expanded version, including two additional items related to lack of interest in medicine/dentistry (F6, α=.543) and two additional COVID-19 stress-related-items (F7, α=.744) also showed acceptable fit indexes (χ2/df=3.513; RMSEA=.061, p<.001; CFI=.88.; TLI=.866, GFI=.892). This new version’s α was of .896. Pearson correlations between ISSME and the other measures were significant (p<.01) and high: >.55 with DASS and >.50 with MBI-SS. Girls presented significantly higher ISSME scores. F6 score was significantly higher in dentistry students. Conclusions This further validation study underlines that IASSME presents good validity (construct and convergent) and reliability. Disclosure No significant relationships.

Introduction Self-Generated Stress might be defined as stress that is created by oneself by engaging in behavior or making decisions that ultimately add strain to pre-existing personal stress. The Self-Generated Stress Scale (SGSS; Flett et al. 2020) is a seven-item self-report measure built to assess this tendency to make one’s own life more stressful. Objectives To analyze the psychometric properties of the Portuguese Version of the SGSS. Methods Participants (127 medicine and dentistry students; 78.0% female) answered an online survey including the preliminary Portuguese version of the SGSS and other validated questionnaires: Maslach Burnout Inventory – Students Survey, Depression Anxiety and Stress Scales, HEXACO-60 and Big Three Perfectionism Scale. Results Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes (χ2/df=1.546; RMSEA=.0666, p<.001; CFI=.982 TLI=.972, GFI=.960). The Cronbach’s alfa was .868. Pearson correlations between SGSS and the other measures were significant (p<.01) and moderate/high: Burnout, .412; Stress/Anxiety/Depression, >.550; Perfectionism, .600; Emotionality, .315; Extroversion, -.411. After controlling for the effect of Emotionality and Extroversion, SGSS explained significant additional increments of 19.9% and 14.0% of the DASS and MBI variance; controlling for Perfectionism, the increments were respectively of 27.9% and 2.0%. SGSS mean score (22.96±5.90 was not significantly different by gender. Conclusions As observed with the original English-language scale, the Portuguese version of SGSS showed good validity (construct and convergent-divergent) and internal consistency. As such, the SGSS might be useful in further investigation, particularly to explore the different pathways between personality traits, emotional regulation processes and psychological distress.
