Predictors of Treatment Response in Adolescent Depression

get link Depressed ChildrenOften, depression in adolescents goes undiagnosed, and is therefore undertreated. Even when treatment is provided, remission rates are frequently between 30 and 40 percent.[1] Adolescents who continue to suffer from depression perform poorly in school, begin to show signs of suicidal ideation and behaviors, and are more likely to form substance abuse dependence.[2] Researchers have found that in order to successfully treat an adolescent’s depression, treatment must begin soon after the onset of symptoms, and such treatment must be tailored specifically to the individual adolescent’s needs.[3] Each adolescent is different; some only require medicine for improvement, others respond well to therapy, and yet another few will need the assistance of both to see symptom improvements.1 Pinpointing the characteristics that will respond successfully to certain treatments was the focus of three large-scaled studies: Treatment for Adolescents with Depression Study (TADS), Treatment for SSRI-Resistant Depression in Adolescents (TORDIA), and Adolescent Depression Antidepressant and Psychotherapy Trial (ADAPT). These three studies focused on demographic, illness, and family characteristics, as well as co-occurring disorders and treatment courses.1

The TADS study reported that medicine alone or medicine plus CBT proved to be the most effective methods of treatment during the first 12 weeks of the study; however, by week 18, CBT alone had also begun to show results that were just as effective.1 The TORDIA study found that SSRI plus CBT was a more effective method of treatment compared to SSRI alone.5  Conversely, the ADAPT study reported that there was no difference in the effectiveness of the SSRI only or SSRI plus CBT treatment methods.6 Age-wise, the TADS study reported adolescents 15 years and younger had better outcomes during the study, while the TORDIA study found that adolescents 18 and 19 years had better overall outcomes.[7] Also, the TADS study found that while gender did not have an effect on treatment initially, follow-up data showed that females were more likely to relapse than males.[8]

TADS and TORDIA reported that higher levels of family stress and conflict was associated with poorer treatment outcomes, and participants who experienced better family communication, more family involvement, and agreed with family rules and values responded well to medicine plus CBT therapy.7 Regarding history of abuse and trauma, TADS reported that patients who had experienced either responded well to both medicine alone or medicine plus CBT.1 They did not respond well to CBT alone, as the CBT for all three studies was focused around depression and not trauma or abuse.

watch Overall, the studies revealed that certain characteristic changes by week 12 of treatment can predict whether the patient will experience a relapse of depression or make a recovery.1 Both TADS and TORDIA found that patients who showed less symptoms of depression by week 12 were more likely to make a recovery.1 However, TORDIA also reported that a decrease in characteristics such as hopelessness, suicidal ideation, anxiety, and family conflict by week 12 also foreshadowed patient recovery.3
