Cognitive Behaviour Therapy for Insomnia Among Older Adults With Depression

1. Cognitive Behaviour Therapy for Insomnia (CBT-I): Participants who are randomly allocated to participate in the Cognitive Behaviour Therapy for insomnia group will be asked to attend 8 weekly, 60-90 minute treatment sessions that involve learning more about their sleep pattern, and identifying unhelpful habits that may be contributing towards their sleep difficulties. Participants will learn several skills that aim to improve their sleep pattern and sleep quality. They will also be provided with information and worksheets during the program which are designed to help improve their sleep pattern. Participating in this form of therapy requires time and commitment. It will take perseverance to make sustainable changes to their sleep habits, and therefore the strategies that they will learn need to be practiced each day during the trial. Participants in this group will be supported by two qualified therapists who have received specialised training and supervision in this therapy. The 8 treatment sessions will be provided in small groups at the local mental health service venue. This will give participants an opportunity to meet other people who are experiencing similar problems and support each other in making changes to their sleep habits. 2. Cognitive Behaviour Therapy for Insomnia and Depression (CBT-I-D) Participants who are randomly allocated to the Cognitive Behaviour Therapy for insomnia and depression group will receive the same program as the group described above. This group, however, will include additional strategies that are specifically designed to also improve their mood. This will involve assisting to increase their level of daily meaningful activity and help them to refocus their attention on positive thoughts rather than depressive negative thoughts.
