Psychotherapy can help with a wide range of different mental-health problems. There is good evidence to support this but little research has been done into whether psychoanalytic psychotherapy is effective in treating young adults. A team of Swedish researchers, led by Annika Lindgren from the Karolinska Institute in Stockholm looked into this issue in a study of 134 young adults who underwent long-term psychodynamic psychotherapy. The study found that on all the measures used people got significantly better from the time they started treatment to a follow-up check after they had finished. Interestingly a lower therapist-rated alliance - how well the therapist thought they and the patient were working together) was linked to a better outcome; perhaps because of the extra work therapists put in to improve a relationship they saw as less-than-satisfactory.
