The relative importance of needs among traumatized and non-traumatized samples

Typically, people rate enhancement needs as more important than security needs to their well-being. Two studies tested whether event valence and prior trauma moderate relative need importance. Traumatized (hurricane survivors) and non-traumatized (control) participants recalled the most “distressing” (security-relevant) or “satisfying” (enhancement-relevant) event they had recently experienced and rated the importance of 10 needs in defining the event. In both studies, event valence moderated relative need importance on explicit (salience) and implicit (affect) measures as enhancement needs were more important for enhancement-relevant (satisfying) events whereas security needs were more important for security-relevant (distressing) events. However, results also suggest that differences in traumatic experience across samples moderated the effect of event valence on relative need importance. Unlike non-traumatized (control) participants, traumatized (hurricane survivors) participants did not reassign greater importance to enhancement over security needs when event valence shifted to enhancement-relevant (satisfying) memories. We close by discussing implications for human motivation.
