The NPV-J (Dutch: Junior Nederlandse Persoonlijkheidsvragenlijst, NPV-J; Luteijn, van Dijk, and Barelds, 2005) is a large Dutch personality inventory. The NPV-J consists of 105 mostly positively formulated items and is intended to determine how adolescents between 9 and 15 years of age judge their own behavior. The NPV-J has five subscales; the InadequacyScale data concern scores of 806 adolescents on 28 items measuring inadequacy (one of the subscales). The data are dichotomous (0 = Disagree, 1 = Agree). The original sample consisted of 866 respondents, however 60 all-0s or all-1s response vectors were removed from the data.
The data are dichotomous scores of a Dutch intelligence test on number completion (Dutch: "Cijferreeksen", Drenth and Hoolwerf, 1970). The file consists of archival data that were collected in a high-stakes personnel selection context around 1990.
These data are from the Physical Functioning scale of the SF-36 (Ware and Sherbourne, 1992). Data consist of scores of 714 respondents on 10 polytomously scored items (0 = no, not limited at all; 1 = limited a little; 2 = limited a lot).
