Abstract
Self-identity is considered as a useful additional predictor in the theory of planned behaviour (TPB).However, previous research generally assessed the impact of pro-environmental self-identity in relationto single behaviours and no studies considered its potential role in moderating the impact of otherpredictors on behaviour. The present research used a within-persons approach to examine effects acrossbehaviours and a longitudinal design to assess the moderating role of self-identity in the prediction ofintentions and behaviours, controlling for past behaviour. Participants (N ¼ 240) completed Time 1questionnaires measuring TPB constructs in relation to five different pro-environmental behaviours. Twoweeks later, participants (N ¼ 220) responded to a questionnaire assessing self-reports of these behavioursduring the intervening two-week period. Across pro-environmental behaviours the findingsshowed that pro-environmental self-identity significantly moderated the impact of perceived behaviouralcontrol on intentions and the effect of past behaviour on both intentions and behavioursI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
