How to read the SDS depression scale

Screen recent depressive symptoms

The SDS helps you reflect on low mood, reduced interest, fatigue, sleep, appetite, and daily functioning as a concise depression screening reference.

Track patterns over time

A single score is less useful than the pattern across weeks. Pay attention to trends, triggers, and whether symptoms affect work, study, sleep, or relationships.

Seek support when symptoms persist

If symptoms last, intensify, or include thoughts of self-harm, speak with a mental health professional or a trusted person as soon as possible.

Test Description

Self-Rating Depression Scale is an English-localized assessment focused on depressed mood, sleep, appetite, fatigue, psychomotor changes, hopelessness, and daily functioning. It contains 20 items across 1 scoring dimension, and it presents the same user-facing testing flow, scoring cues, and report context in English. Use the report as a self-reflection and screening reference rather than a standalone diagnosis; important mental health or relationship decisions should still be discussed with a qualified professional when needed.
