Individual therapy involves a client meeting one-on-one with a licensed therapist. Whether you call it psychotherapy, counseling, or talk therapy, the format’s the same: your therapist focuses entirely on you and what you need. Most sessions run 45 to 75 minutes and occur weekly, although you may meet more frequently during intensive treatment phases.
Here’s what makes individual therapy different from group or family sessions:
- Personalized attention: The therapist focuses entirely on one client’s specific needs and goals
- Confidential environment: A private setting encourages open, honest communication about sensitive topics
- Flexible approach: Therapists can adapt techniques and pace to individual preferences and progress
- Therapeutic alliance: A strong relationship between a client and their therapist improves the chances of staying in recovery.
Evidence-Based Individual Therapy
Therapists use research to determine which treatments are most effective for various problems. National Institutes of Health research shows that individual therapy reduces symptoms across addiction, depression, anxiety, and PTSD.
Key research findings include:
- Retention advantages: More people finish individual addiction counseling than some other treatment formats
- Co-occurring disorder effectiveness: Individual therapy works better for people dealing with PTSD alongside addiction
- Long-term benefits: The progress people make in individual therapy lasts, social connections and daily functioning stay improved years later

Individual therapy addresses mental health conditions and addiction in one-on-one sessions. Therapists use proven approaches to help with addiction, anxiety, depression, and trauma, adjusting their methods based on what each person needs.
Substance Use Disorders
Individual therapy works for alcohol and drug addiction because therapists can personalize their approach. Addiction changes your brain’s reward system, affecting how you experience pleasure and what motivates you.
Therapists help you spot what triggers cravings, build skills to handle them, and plan how to avoid relapse. Individual therapy pairs well with medication-assisted treatment and support groups. Studies show people are more likely to finish individual counseling in community programs.
Co-occurring Mental Health Conditions
Co-occurring disorders are mental health conditions that show up with addiction, and they need to be treated together. Individual therapy addresses anxiety, depression, PTSD, and other conditions that often come with addiction. Research shows that individual therapy works better than group therapy for people with PTSD alongside addiction.
Common co-occurring conditions treated with individual therapy include:
- Depression: Ongoing sadness, losing interest in things you used to enjoy, and changes in sleep or appetite
- Anxiety disorders: Constant worry, panic attacks, and physical symptoms like a racing heart
- PTSD: Flashbacks, nightmares, and avoiding anything that reminds you of trauma
- Bipolar disorder: Mood swings between depression and mania, affecting energy and decisions
Trauma and PTSD
Trauma from abuse, accidents, or violence often leads to addiction, and it needs specialized treatment. PTSD happens when trauma symptoms stick around and mess with your daily life. Individual therapy gives you a place to work through trauma without anyone judging you.
Eye Movement Desensitization and Reprocessing (EMDR) helps you work through traumatic memories. Research shows individual therapy works just as well as EMDR for treating PTSD. Trauma-informed care looks at how past experiences shape your current behavior, helping you see how trauma and substance use are connected.
