The GAD-7 (Generalized Anxiety Disorder 7-item scale) is a brief screening and severity measurement tool for generalized anxiety disorder. Format: self-administered questionnaire; takes about 2 minutes; can be paper or electronic; each item asks about anxiety symptoms over past 2 weeks. The 7 items: feeling nervous, anxious, or on edge; not being able to stop or control worrying; worrying too much about different things; trouble relaxing; being so restless it’s hard to sit still; becoming easily annoyed or irritable; feeling afraid as if something awful might happen. Each scored 0 (not at all) to 3 (nearly every day); total 0-21. Score interpretation: 0-4 minimal; 5-9 mild; 10-14 moderate; 15-21 severe. Also useful as preliminary screen for other anxiety disorders (panic disorder, social phobia, PTSD). Validated, freely available, no licensing fee. Often paired with PHQ-9 for combined depression/anxiety screening. Significantly more common than in general population. Statistics: anxiety disorders affect about 20% of adults with diabetes (general population about 12-15%); about 40% of adults with diabetes have elevated anxiety symptoms even if not meeting full disorder criteria. Specific anxiety subtypes: generalized anxiety disorder (persistent worry; about 14% prevalence in diabetes); diabetes-specific distress (worry about diabetes management, complications, future; very common; about 30-45% prevalence); hypoglycemia anxiety (fear of low blood sugar; particularly common in type 1 diabetes and insulin users); needle/blood phobia (interferes with self-care); panic disorder (sometimes confused with hypoglycemia); social anxiety related to diabetes management. Impact: poor glycemic control (anxiety affects self-management); avoidance of self-monitoring; reluctance to take medications appropriately (especially insulin); avoidance of healthcare appointments; worse complications. Bidirectional — diabetes worsens anxiety; anxiety worsens diabetes outcomes. Screening important; treatment effective. Diabetes distress refers to the emotional burden specifically related to living with diabetes — worry about complications, fatigue from constant self-management, frustration with healthcare system, social burden. Different from clinical depression or anxiety disorder. DDS-17 (Diabetes Distress Scale — 17 items) — validated screening tool with subscales: emotional burden, physician-related distress, regimen-related distress, interpersonal distress. Score: each item 1 (no distress) to 6 (serious distress); average score above 3 considered elevated. About 30-45% of adults with diabetes have elevated diabetes distress. Treatment: diabetes-specific cognitive behavioral therapy; diabetes self-management education; peer support groups; addressing specific concerns (complications, costs, regimen burden); not always pharmacologic.
GAD-7 Score Interpretation

|---|---|---|
| 0-4 | Minimal | No treatment |
| 5-9 | Mild | Watchful waiting; lifestyle; repeat 2-4 weeks |
| 10-14 | Moderate | Treatment plan; psychotherapy and/or medication |
| 15-21 | Severe | Active treatment with combination approach often |

Anxiety in Diabetes
- Generalized anxiety disorder — about 14% prevalence in diabetes.
- Diabetes distress — about 30-45% have elevated diabetes-specific worry.
- Hypoglycemia fear — common in insulin users.
- Needle/blood phobia — interferes with self-care.
- Panic disorder — sometimes confused with hypoglycemia.
- Health-related anxiety — about complications.
- Social anxiety related to diabetes (insulin in public, food restrictions).
- About 20% of adults with diabetes have an anxiety disorder.
- Often co-occurs with depression.
Diabetes-Specific Anxiety Issues
- Hypoglycemia anxiety — fear of low blood sugar episodes.
- Hyperglycemia anxiety — fear of long-term damage.
- Complication anxiety — fear of vision loss, amputation, dialysis.
- Death anxiety — fear of dying from diabetes.
- Pump anxiety — fear of equipment failure.
- CGM anxiety — fear of alarms or being constantly monitored.
- Travel anxiety — managing diabetes away from home.
- Food anxiety — constant carb counting; relationships with food.
- Exercise anxiety — fear of hypoglycemia during/after.
- Healthcare anxiety — A1C results, doctor visits.
Treatment Options
- Cognitive behavioral therapy (CBT) — first-line for anxiety.
- Exposure therapy for specific phobias (needles, blood).
- Mindfulness-based stress reduction (MBSR).
- Acceptance and commitment therapy (ACT).
- SSRIs — escitalopram, sertraline — first-line medications.
- SNRIs — duloxetine (also for diabetic neuropathy), venlafaxine.
- Buspirone (Buspar) — anti-anxiety, no addiction risk.
- Avoid long-term benzodiazepines — dependence risk; fall risk in older adults.
- CGM technology may reduce hypoglycemia anxiety.
- Diabetes education reduces uncertainty-driven anxiety.
- Peer support groups (in-person, online).
- Regular exercise — proven anxiolytic.
- Sleep hygiene.
- Limit caffeine and alcohol.
When to See Specialist
- Severe anxiety (GAD-7 score 15+).
- Treatment-resistant anxiety.
- Co-occurring depression with PHQ-9 elevated.
- Suicidal thoughts (immediate evaluation).
- Panic disorder with frequent attacks.
- Specific phobias interfering with diabetes care.
- Substance use as coping mechanism.
- Need for medication management.
- Mental health crisis — 988 Suicide and Crisis Lifeline.

Significantly more common than in general population. Anxiety disorders affect about 20% of adults with diabetes (general population about 12-15%); about 40% of adults with diabetes have elevated anxiety symptoms even if not meeting full disorder criteria. Specific anxiety subtypes: generalized anxiety disorder; diabetes-specific distress (about 30-45% prevalence); hypoglycemia anxiety (particularly common in type 1 diabetes and insulin users); needle/blood phobia; panic disorder; social anxiety related to diabetes management. Impact: poor glycemic control; avoidance of self-monitoring; reluctance to take medications appropriately (especially insulin); avoidance of healthcare appointments; worse complications. Bidirectional — diabetes worsens anxiety; anxiety worsens diabetes outcomes. Diabetes distress (DDS-17) refers to emotional burden specifically related to living with diabetes — worry about complications, fatigue from constant self-management, frustration with healthcare system, social burden. Different from clinical depression or anxiety disorder. About 30-45% of adults with diabetes have elevated diabetes distress. Treatment: diabetes-specific cognitive behavioral therapy; diabetes self-management education; peer support groups; addressing specific concerns; not always pharmacologic. Effective treatments available. Severity-based approach: mild — watchful waiting and lifestyle; moderate — treatment plan with psychotherapy preferred initially; severe — active treatment with combination approach often. Psychotherapy options: cognitive behavioral therapy (CBT) first-line for anxiety; exposure therapy for phobias; mindfulness-based stress reduction; acceptance and commitment therapy. Medication options: SSRIs (escitalopram, sertraline) first-line; SNRIs (duloxetine — bonus for diabetic neuropathy, venlafaxine); buspirone; avoid long-term benzodiazepines (dependence risk, fall risk in older adults, less effective for chronic anxiety). Diabetes-specific approach: hypoglycemia anxiety — CGM device may help, technology assistance reduces fear, diabetes education; needle anxiety — pen devices, technique training, gradual exposure. Lifestyle: regular exercise (proven anxiolytic effect), sleep, limit caffeine/alcohol, mindfulness practice, yoga. Refer mental health specialist for severe or complex cases. For adults with type 2 diabetes — ensure your provider screens for both anxiety and diabetes-specific distress; if positive, effective treatments available; addressing anxiety improves quality of life and diabetes outcomes.
