Neurocognitive Enhancement in Major Depressive Disorder (MDDNET)

August 27, 2015 updated by: Christopher Bowie, Queen's University
The purpose of this study is to examine the effects of neurocognitive enhancement on cognitive abilities and related social and adaptive behaviours in individuals diagnosed with major depressive disorder. Subjects in this study will be randomized to receive Neurocognitive Enhancement Therapy (NET) or to a wait list and then NET . Secondary aims include examining whether the cognitive benefits are potentiated by repeated exposure during in-home practice with complementary exercises. Additionally, the investigators will examine the durability of the effects and their generalization to functional capacity and everyday functional performance after completion of the groups.

Description

Inclusion Criteria:

  1. Male or Female.
  2. Subjects will be between the ages of 18 and 65, which is the age range with available normative comparison data.

Exclusion Criteria:

  1. Presence of a medical diagnosis that is associated with known cognitive impairments, such as multiple sclerosis, cerebrovascular accident, dementia, or history of traumatic brain injury.
  2. Subjects with a reading level below grade 6, as assessed with the Wide Range Achievement Test - Reading Recognition Subtest, will be excluded because of the likelihood of not understanding task instructions.
  3. Subjects with uncorrectable vision or hearing impairment that would preclude valid assessments or intervention procedures.

  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Neurocognitive Enhancement
neurocongnitive enhancement
Behavioral: Neurocognitive Enhancement
Neurocognitive Enhancement Therapy (NET) uses behavioural treatment strategies that are designed to improve a range of cognitive skills. NET uses strategies such as coaching, repetition, practice, teaching, group discussion, and compensation for deficits by using cognitive strengths.
Other: Wait List
no intervention
Behavioral: Wait List
Participants will be wait listed for 10 weeks, following which time they will receive the intervention previously described.
