Internet-based Self-help After Spousal Bereavement or Divorce

The purpose of this study is to evaluate the efficacy of an internet-based self-help intervention for older adults with prolonged grief symptoms after spousal bereavement or separation/divorce. The study design is a randomized trial with a waiting control condition of 12 weeks and a follow-up after 6 months. The investigators will test the following main hypotheses: 1. The intervention group shows a significant decrease in grief symptoms, psychological distress, depression symptoms and embitterment, and a significant increase in life satisfaction, as well as session related outcomes from baseline to 12 weeks post intervention assessment. 2. The effects in the intervention group are larger than the effects in the waiting control group. 3. These effects are stable from the post measure at 12 weeks to the 6-month follow-up.
