Inclusion Criteria:

• Age and consent
• Presence of suicidal ideation or active behavior in the last month, assessed using the C-SSRS (e.g., intentional ideation, plan, or preparatory behavior)
• Depressive or anxious symptoms (Score ≥ 10 on the PHQ-9, indicating at least moderate depressive symptoms, or Score ≥ 10 on the GAD-7, suggesting clinically significant anxiety.)
• Availability and commitment to participate in the full assessment using all the aforementioned scales.

Exclusion Criteria:

• Clinical Safety (exclude and refer immediately)
• Imminent suicide risk according to the C-SSRS (e.g., attempt within the last 7 days, current intentional plan, access to lethal means, and low ambivalence).
• PHQ-9 item 9 = 3 ("almost every day") with clinical corroboration of imminent risk.
• Current self-harm with lethality/high-harm moderator requiring acute restraint.
• Refusal to establish a safety plan or allow emergency contact.
• Acute Psychiatric Conditions/Contraindications of Assessment
• Active psychosis or unstabilized manic episode.
• Substance use disorder in intoxication or acute withdrawal (e.g., last 24-72 hours) that precludes valid assessment.
• Uncontrolled risk of severe other-directed violence.
• Medical or neurological conditions that preclude valid participation
• Severe cognitive impairment (e.g., dementia, recent moderate-to-severe traumatic brain injury) that prevents understanding/answering scales.
• Decompensated medical illness (e.g., desaturation, delirium, severe uncontrolled pain).
• Unstable neurological condition (e.g., uncontrolled seizures).
• Methodological interferences
• Recent changes in baseline psychotropic medications within the last 2 weeks.
• Concurrent intensive psychotherapy initiated within the last 4 weeks.
• Simultaneous participation in another trial that could contaminate results.
• Language other than that of the scales without available validation.
• Logistical impossibility for follow-up (no telephone/stable contact; imminent relocation plan).
• Legal aspects/consent
• Incapacity to consent (legal or clinical) and no available representative.
• Legal restrictions that prevent participation.
