| - | Note that even in the old versions of the questionnaire, i.e. before adding the missing FFI items, the questionnaire did already contain some FFI items: 5 out of 12 FFI neuroticism items, 3 out of 12 FFI conscientiousness items, and 1 out of 12 FFI extraversion items. Therefore, FFI SUM2 and FFI SUM3 are calculated even for subjects who were administered an old version of the questionnaire. Thus, any researcher using these scores must always check the number of missing items per scale and set his/her own threshold for missingness. | + | * Even though all FFI items have been included in only part of the questionnaires, the FFI sum scores have been calculated for all domains. This has been decided because before adding the missing items, the questionnaire did already contain some FFI items. |
