Predicting committed behavior: Exchange ideology and pre-entry perceived organisational support

A longitudinal field study conducted in a military setting examined the effects of exchange ideology, pre-entry Perceived Organisational Support, and their interaction, on initial and long-term committed behavior. The effect of exchange ideology was compared to that of a solidly validated biodata score which was assessed with a structured interview. The sample consisted of 1,276 conscripts to military service. Results showed that exchange ideology had effects on both initial and long-term committed behavior; these effects were stronger than those of pre-entry Perceived Organisational Support, and comparable to those of the biodata structured interview.
