Goal pursuits are strongly influenced by romantic partners, and a partner's instrumentality to goals may be particularly important for goal pursuit. This study examined the effects of partner instrumentality on goal-related effort, goal progress, goal commitment, and relationship satisfaction over time. It also examined whether relationship satisfaction moderated the effects of partner instrumentality on goal pursuit processes. Newly dating romantic partners (N=59 couples) reported on their goals and relationship satisfaction at two assessments 3months apart. Multilevel models indicated that partner instrumentality predicted increases in progress over time but only for those high in relationship satisfaction. Partner instrumentality also predicted increases in one's own relationship satisfaction but was unrelated to changes in the partner's satisfaction. These findings suggest that partner instrumentality benefits increased goal progress, particularly for those with satisfying relationships, and further increases relationship satisfaction.
