Research has shown that depressed individuals perceive significant others as rejecting and unsupportive; however, the thoughts, feelings and behaviours of significant others are often underexamined. Guided by interpersonal theory and self-determination theory, this thesis examined the associations between significant others basic psychological needs, helping motivations, and interpersonal behaviours toward depressed individuals in an undergraduate sample (Study 1) and a community sample (Study 2). Need satisfaction and autonomous motivation to help were generally associated with more dominant and loving support (i.e., directive and nurturing) whereas need frustration and controlled motivation to help predicted less helpful forms of support (i.e., critical and avoidant). Autonomous motivation to help further interacted with basic psychological needs to predict supportive behaviours. These studies highlighted the interpersonal and motivational aspects of support provided to depressed individuals from the perspective of significant others.Author owns copyright, except where explicitly noted.
