Dear Colleague, I am writing this message to invite "Mental Health Researchers" who are interested to contribute to cross-sectional research projects in Saudi Arabia. The task would be simply selecting the right questionnaire and contributing as you can with no other obligations. You would be a co-author on many papers as you contribute to finding and or making the right questionnaire for each research study. If you are interested, Please send an email to: sami.almustanyir@gmail.com Thanks Sami Almustanyir, MD
