Description

The generative concern scale (GCS) and the generative behavior checklist (GBC) based on the multifaceted model of generativity (McAdams & de St. Aubin, 1992) were reconstructed based on item analysis in preliminary research. The reconstructed scales were administered to 996 adults. Factor analysis of GCS-R and GBC-R data revealed the following three factors which showed high internal consistency: offering, maintaining, and creativity. Significant positive correlations between the GCS-R and the GBC-R implied that generative concern may lead to generative behavior. The GCS-R and GBC-R showed significant positive correlations with the Erikson Psychosocial Stage Inventory (Nakanishi & Sakata, 1993) and the Inventory of Psychosocial Balance (Domino & Affonso, 1990), which supports concurrent validity. Adults with higher scores on the GCS-R were more extroverted, open-minded to experiences, and the less depressive based on scores on the Big Five Scale (Wada, 1996) and the Beck Depression Inventory (Hayashi & Takimoto, 1991). These results indicate convergent and predictive validity.
