The number and variety of psychological interventions have risen dramatically over the past several decades. For example, psychologists concerned with improving working conditions have designed and implemented interventions that prevent poor mental health and promote high-quality reemployment for unemployed people (Vinokur, van Ryn, Gramlich, & Price, 1991), that improve various aspects of work performance (see Guzzo, Jette, & Katzell, 1985), and that enhance the quality of work life (see Mohrman, Ledford, Lawler, & Mohrman, 1986). Educational applications include programs that provide compensatory education for the underprivileged (see Hodges & Cooper, 1981; House, Glass, McLean, & Walker, 1978) and increase the social functioning of at-risk elementary school children (King & Kirschenbaum, 1990). Programs related to forensic psychology include domestic violence reduction (Sherman & Berk, 1984) and juvenile delinquency curtailment (see Lipsey, 1988). Some examples from the health area are interventions to prevent heart disease (Farquhar et al., 1990), encourage healthy life-styles (Nathan, 1984), and reduce the onset of adolescent substance use (for recent reviews see Flay, 1985; Hansen, 1990).
