I was in drug/alcohol rehab for 6 months in 1994 and my 2nd rehab was in 2019 for 3 months at PSI. Both were excellent but the first used a gestapo chain-gang approach with excessive rules and restrictions. PSI was refreshingly open and positive, treating patients like adults. The “positive” part of the PSI name underscores the unique inclusion of positive psychology principles. Cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT) skills are introduced over the first four weeks of treatment and are reemphasized over the next 2-4 weeks so that the depth of the information is well ingrained before the patient is reintroduced to the “real world”. Yoga, meditation and sound therapy were helpful for me. Integration of family therapy was successful due to the skill of the staff. The counselors were universally top-notch (especially mine – insert smile emoji). The educational part of the program included reviewing addiction science by the erudite Medical Director. His book and class lessons were enlightening and extremely helpful. Even if you do not select PSI for whatever reason, I would strongly recommend reading Dr. Angres’ book as it encapsulates the best parts of the PSI program.
