C. Hetherington (1991) hypothesized that lesbian, gay, and bisexual (LGB) adolescents may experience a "bottleneck effect" in career development because of internal psychological energy focusing on issues surrounding sexual identity. This assertion has not yet been tested, however, in the career development literature. The authors examined the relationship between variables indicative of psychological resources being devoted to managing an LGB identity, social support, and career development. Survey data from 102 LGB youth demonstrated that inner sexual identity conflict and social support predicted unique and shared variance in career maturity and vocational indecision, lending empirical support to the bottleneck hypothesis.
