Depression severity as measured by the Patient Health Questionnaire-8 (PHQ-8)
大体时间:5 weeks
|
Depression severity as measured by the Patient Health Questionnaire-8 (PHQ-8). The PHQ-8 assesses depression severity over the past two weeks. Total scores range from 0 to 24, with higher scores indicating greater depression severity (worse outcome). Score interpretation: 0-4 (none), 5-9 (mild), 10-14 (moderate), 15-19 (moderately severe), 20-24 (severe depression). |

|
Anxiety severity as measured by the Generalized Anxiety Disorder-7 scale (GAD-7)
大体时间:5 weeks
|
The GAD-7 assesses anxiety symptom severity over the past two weeks. Total scores range from 0 to 21, with higher scores indicating greater anxiety severity (worse outcome). Score interpretation: 0-4 (minimal anxiety), 5-9 (mild), 10-14 (moderate), 15-21 (severe anxiety). |

Suicidality as measured by the C-SSRS (Columbia-Suicide Severity Rating Scale)
大体时间:5 weeks
|
The C-SSRS assesses the presence and severity of suicidal ideation and behavior. Suicidal ideation severity scores range from 0 to 5 (0=no ideation, 1=wish to be dead, 2=non-specific active suicidal thoughts, 3=active suicidal ideation with methods, 4=suicidal intent, 5=suicidal intent with plan), with higher scores indicating greater severity (worse outcome).
