 The PBI consists of 2 sets of 25 items (1 set per parent). Participants were asked to fill in the questionnaire for their biological mother and father, if these parents raised them in the first 16 years of their lives. If one or both biological parents were involved in their upbringing for less than 4 years, participants were asked to fill in the questionnaire for the most important/involved parental figure(s) (e.g. step- or foster parent) instead.\\
+Note that in OPBQ, **item 02** differs from the original PBI (phrased as a confirmatory rather than a negative question).
 In OPBQ, 2 extra questions for each  parent ('parent 1' and 'parent 2' as indicated for the PBI) were added to assess parental  optimism.
