Treatment Plan for Moderate Anxiety with Mild Depression
This patient requires initiation of pharmacologic treatment with an SSRI (such as duloxetine 30-60 mg daily) combined with low-intensity psychosocial interventions, given the moderate anxiety (GAD-7=10) as the primary driver of functional impairment, alongside monitoring for substance use and close follow-up for the mild depressive symptoms. 1, 2
Symptom Severity Classification
Your patient's screening scores indicate:
- Moderate anxiety (GAD-7=10, threshold for moderate is ≥10) 3, 4
- Mild depression (PHQ-9=7, range 1-7 indicates minimal symptoms) 3, 1, 4
- Low substance use risk (CAGE-AID=1) requiring monitoring but not immediate intervention
- Significantly impaired quality of life (5/16) suggesting functional impact despite "mild" symptom scores
- No acute suicidal ideation (C-SSRS N/A)
Primary Treatment Approach
Pharmacologic Management
Start an SSRI for the moderate anxiety, as this is the dominant clinical problem. 1, 2
- Duloxetine 30 mg once daily for 1 week, then increase to 60 mg once daily is the recommended starting approach for generalized anxiety disorder 2
- The 60 mg daily dose is the target, with no evidence that higher doses provide additional benefit 2
- SSRIs have demonstrated efficacy in treating generalized anxiety disorder and will also address the mild depressive symptoms 1
- Reassess after 4-6 weeks to determine response and need for dose adjustment 2
Psychosocial Interventions (Low-Intensity)
Implement structured low-intensity interventions appropriate for the mild depressive component: 3
- Individually guided self-help based on cognitive behavioral therapy (CBT), including behavioral activation and problem-solving techniques 3
- Structured physical activity program 3
- Group-based CBT for depression if available 3
Diagnostic Clarification Required
Before finalizing the diagnosis, rule out medical and substance-induced causes: 3, 1
- Obtain thyroid function tests, complete metabolic panel, complete blood count, vitamin B12 and folate levels 1
- Review all current medications for mood-altering side effects (corticosteroids, beta-blockers, interferon) 3, 1
- Assess for uncontrolled pain, fatigue, or other medical conditions contributing to symptoms 1
- Evaluate the positive CAGE-AID response: determine specific substance use patterns and whether they are contributing to anxiety/depression 3
Monitoring and Follow-Up Strategy
Establish a structured reassessment schedule: 3, 2
- Repeat PHQ-9 and GAD-7 at 2-4 week intervals to track symptom response 1, 4
- Monitor for emergence of suicidal ideation, particularly item 9 on PHQ-9 ("thoughts that you would be better off dead") 3, 1
- Reassess functional impairment using the quality-of-life measure and the functional impairment questions on PHQ-9/GAD-7 3, 1
- Address substance use patterns identified by CAGE-AID through brief interventions or referral if escalation occurs
Referral Thresholds
Refer to psychiatry/psychology if: 3, 1
- PHQ-9 increases to ≥15 (moderate to severe or severe symptomatology) 3, 1
- GAD-7 increases to ≥15 (severe anxiety) 1, 4
- Any emergence of suicidal ideation, psychosis, severe agitation, or confusion 3
- Inadequate response to initial SSRI trial after 8-12 weeks at therapeutic dose 2
- Substance use escalates or interferes with treatment 3
Critical Pitfalls to Avoid
Do not underestimate functional impairment based solely on "mild" PHQ-9 scores. 1
- The low quality-of-life score (5/16) indicates significant functional impact that warrants active treatment, not just watchful waiting 1
- The GAD-7 score of exactly 10 places this patient at the threshold for moderate anxiety, justifying pharmacologic intervention 1, 4
- Do not omit item 9 from PHQ-9 assessments, as this artificially lowers scores and misses critical suicide risk information 3, 1
- Failing to address the positive CAGE-AID response could allow substance use to undermine treatment effectiveness 3
- Make full functional recovery—not just symptom remission—the treatment goal 1
Treatment Intensity Justification
The combination of moderate anxiety (primary diagnosis), mild depression, and significantly impaired quality of life justifies active pharmacologic treatment plus low-intensity psychosocial interventions rather than watchful waiting. 3, 1 The moderate anxiety drives the need for SSRI initiation, while the mild depression responds well to low-intensity CBT-based interventions. 3, 2 This stepped-care approach balances treatment intensity with symptom severity while addressing the disproportionate functional impairment. 1
