Brief summary
The present study is a case series where individuals with a diagnosis of major depressive disorder will be offered 12 sessions of imagery rescripting. The first aim will be investigated using cross-sectional data collected at the baseline phase: to examine the prevalence, content, characteristics and responses to intrusive memories reported by participants. The second aim is to determine whether participants endorse features of maladaptive schema modes - as outlined in Young's (2006) Schema Mode Model. The final aim is to evaluate whether a 12-session imagery rescripting intervention is efficacious at reducing symptoms of major depressive disorder, as well as intrusive memories and rumination. Hypotheses: 1. Participants will report frequent and distressing intrusive memories about a range of negative autobiographical events. Intrusive memories will be associated with the severity and maintenance of depressive symptomology. 2. Intrusive memories that are experienced as predominantly sensory will be associated will greater distress than those experiences as predominantly verbal. 3. Rumination will be positively associated with intrusive memories. 4. Participants will report activation of maladaptive child, parent and coping schema modes. Schema mode activation will be associated with the severity and maintenance of depressive symptomology. 5. Following 12 sessions of imagery rescripting, participants will experience less frequent and distressing intrusive memories, as well as reduced rumination and depression symptomology.
Interventions
Participants will attend 12 90 minute sessions, conducted weekly, in which they will be guided by the psychologist to identify an autobiographical event linked to their intrusive memories. The participant will be asked to rate the belief and affect associated with the memory out of 100.
Participants will then be guided to imaginally relive the event in as much detail as possible, describing what is occurring and how they feel. During the reliving, participants will be asked what they need to c

The participant will be asked to rate the belief and affect associated with the memory out of 100. Participants will then be guided to imaginally relive the event in as much detail as possible, describing what is occurring and how they feel. During the reliving, participants will be asked what they need to change in the scene in order to feel better emotionally. The therapist and participant will then collaboratively rescript the memory accordingly. Participants will then be asked to re-rate their original belief and affect about the event. In subsequent sessions further modifications to the memory will be conducted as required, and additional intrusive memories will be identified and rescripted.
