Social Responsibility (SR). The TBR Questionnaire was designed to include 44 masking items derived from the Social Responsibility scale of the California Psychological Inventory (CPI; Gough, 1957; Gough, McCloskey, & Meehl, 1952; Schaie, 1959b). The scale is of interest because it has allowed us to chronicle attitudinal shifts toward society over time (Schaie, 2005; Schaie & Parham, 1974) as well as attitudinal differences within families (Schaie, Plomin, Willis, Gruber-Baldini, & Dutta, 1992).
Derived Traits. A factor analysis of the 75 items contained in the TBR questionnaires collected during the first three study cycles resulted in the identification of 19 personality factors, several of which could be matched in content to at least one of the poles of the Cattell et al, 16-PF scale (Schaie & Parham, 1976). More recently we have replicated 13 of these factors for the entire database through the fifth SLS cycle (Maitland, Dutta, Schaie, & Willis, 1992; Willis, Schaie, & Maitland, 1992; see also Schaie, 2005, chapter 12).
The NEO Personality Questionnaire (Form R). This 240-item personality questionnaire representing the big 5 personality factors (Costa & McCrae, 1992) was administered by mail in 2001 to individuals participating in the 1996/97 family study and in the 1998 longitudinal cycle. The questionnaire was readministered as part of the 2004/05 family study and the 2005/06 eighth wave of the longitudinal study. The questionnaire measures the personality factors of neuroticism (N), extroversion (E), openness to experience (O), agreeableness (A), and conscientiousnes (C). Each of these factors is defined by a number of more specific traits or facets (Costa & McCrae, 1992).
