Jika anda kira anda mungkin menderita depresi musim dingin, Terman menyarankan, sebagai langkah awal, tuntaskan survei Temuan Pribadi bagi Depresi dan SAD, daftar pertanyaan penilaian pribadi on-line yang rahasia dan bebas yang dikirim melalui Internet nir-laba dari 'Center for Environmental Therapeutics, www.cet.org'.
If you think you may suffer from winter depression, Terman suggests, as a first step, completing the Personalized Inventory for Depression and SAD survey, a free and confidential online self-assessment questionnaire posted on the nonprofit website of the Center for Environmental Therapeutics, www.cet.org.
