Study summary

The goal of the clinical trial is to determine whether the Islamic Workbook of Scrupulosity treats scrupulosity in adults. The main question is whether patients show fewer scrupulosity symptoms after receiving the workbook treatment, as measured by various self-report scales. Participants will be divided into three groups; the first group will receive the intervention after the baseline measurement. The second group will receive treatment 6 weeks after baseline. The last group will serve as a control group. The groups will be randomly assigned. All groups will have symptoms measured at baseline, 6 weeks after baseline, and 12 weeks after baseline.

    This intervention includes Islamically integrated psychoeducation for scrupulosity. We also included Islamically integrated cognitive and behavioral interventions. The cognitive intervention included spirituality as part of a healthy psyche. In addition to cognitive and behavioral interventions, we included emotional interventions, especially the two-chair technique. We also included spiritual interventions such as prayers, dhikrs, and expressing gratitude to God.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
