“…These variables derive not only from social-cognitive personality theories (e.g., Bandura, 1986;Mischel, 1973Mischel, , 1982Rotter, 1955Rotter, , 1982 and the action theory model of personality (Krampen, 1988(Krampen, , 1991a, but also from empirical political socialization research (summarized, e.g., by Niemi, 1973;Sears, 1983Sears, , 1987. These empirical results point toward the significance of the self-concept of one's own (political) competence (see, e.g., Carmines, 1991;Mengering, 1992) and its domain-specific differentiation, especially in adolescence (see, e.g., Adams, 1985;Byrne & Shavelson, 1996); internal locus of control (see, e.g., Majete, 1987;Peterson & Maiden, 1992-93); political knowledge (see, e.g., Hyman, 1973;Lanoue, 1992;Prester, Rohrmann, & Schellhammer, 1987); and trust in politics (see, e.g., Marsh, 1977;Sabucedo & Cramer, 1991) for political participation as well as well-being of adolescents and adults.
