Model 1: MIDI conscientiousness with age, gender, and level of education, N = 11,360.

Model 2: MIDI conscientiousness with age, gender, level of education, and other Big Five traits, N = 10,682.

Model 3: MIDI conscientiousness and work status interaction with all controls, N = 10,682.

Model 4: MIDI conscientiousness time 1 and work status time 2 predicting volunteering time 2 with all controls, N = 5017.
