Type of Study: Within-group pre-/post-test design
Number of Participants: Phase I: 5; Phase II: 14
Population:
- Age range — 12-18 years
- Race/Ethnicity — Phase II: 11 Hispanic, 3 African-American
- Gender — Phase II: 2 males, 12 females
- Status — Participants (for both phases) were referred for treatment for
depression to the Children’s Anxiety and Depression Clinic at Columbia
Presbyterian Medical Center or the Research Clinic at New York State
Psychiatric Institute.
Location / Institution: New York
Summary: (To include comparison groups, outcomes, measures, notable limitations)
These studies tested the efficacy of Interpersonal Psychotherapy for Depressed Adolescents (IPT-A).
In phase I, therapeutic methods were explored and refined in a small
sample of depressed adolescents (n=5); these participants did not
receive any assessment measures. In phase II, 14 depressed adolescents
participated in a 12-week open clinical trial of IPT-A. Measures included the Schedule for Affective Disorders and Schizophrenia for School-Age Children – Epidemiologic Version (K-SADS-E), which assesses diagnoses at evaluation and termination; Hamilton Rating Scale for Depression (HRSD), in order to measure changes in depressive symptomatology over the course of treatment; Global Assessment Scale for Children (C-GAS), which assesses global functioning; Beck Depression Inventory (BDI), which assesses treatment outcome for depressive symptoms; the Social Adjustment Inventory for Children and Adolescents (SAICA), which evaluates social functioning; and the Symptom Checklist (SCL-90),
in order to assess changes in psychological and physical symptoms of
distress over the course of treatment. The results of phase II showed a
significant decrease in participants’ depressive symptoms and symptoms
of psychological and physical distress, as well as a significant
improvement in functioning over the course of treatment. None of the
subjects met criteria for depression at termination (week 12).
Limitations of these studies include the small sample size, lack of
follow-up data, and lack of control group.
Length of post-intervention follow-up: None.

Type of Study: Within-group naturalistic follow-up
Number of Participants: 10 (out of original 14 in open clinical trial, Mufson et al., 1994)
Population:
- Age range — Mean age at follow-up: 17.5 years
- Race/Ethnicity — 7 Latinas, 3 African-Americans
- Gender — 100% female
- Status — Participants included 10 of the 14 adolescents who had participated in the 12-week open clinical trial of IPT-A (Mufson et al., 1994)
Location / Institution: New York
Summary: (To include comparison groups, outcomes, measures, notable limitations)
In an open clinical trial, 14 participants had completed 3 months of Interpersonal Psychotherapy for Depressed Adolescents (IPT-A)
(Mufson et al., 1994). Approximately 1 year after completion of
treatment, the original 14 subjects who had participated were sent a
letter asking permission to contact them regarding participation in the
follow-up study; ten of the 14 original participants completed the
follow-up evaluation. Measures included the Schedule for Affective Disorders and Schizophrenia for School-Age Children – Epidemiologic Version (K-SADS-E),
which is a semi-structured diagnostic interview that has been
demonstrated in previous studies to diagnose depression in adolescents;
the Life Events Questionnaire, which assesses life events in the categories of conflict, loss, violence, abuse, suicide, and parental disorder; the Beck Depression Inventory (BDI), a self-report instrument to assess depressive symptoms; the Hamilton Rating Scale for Depression (HRSD), which also assesses depressive symptoms; the Symptom Checklist (SCL-90), which is another self-report inventory to measure psychopathology; the Social Adjustment Scale – Self-Report (SAS-SR), which measures social functioning; and Children’s Global Assessment Scale (C-GAS),
which measures global functioning. Only 1 of the 10 subjects who
participated in the follow-up study reported having a current diagnosis
of depression. The results of the follow-up suggest that the
improvements that occurred during the course of the 12-week clinical
trial were maintained for the year immediately following completion of
treatment. Limitations of the study include the small sample, the
questionable generalizability of a 100% female sample, lack of a control
group, and the lack of control over the type and amount of treatment
adolescents may or may not have received after completing the open
trial.
Length of post-intervention follow-up: 12 months.

Type of Study: Randomized controlled trial
Number of Participants: 48
Population:
- Age range — 12-18 years
- Race/Ethnicity — Clinical Monitoring Group: 62.5% Hispanic, IPT-A Group: 79.2% Hispanic (rest unspecified)
- Gender — Clinical Monitoring Group (n=24): 70.8% female, 29.2% male; IPT-A Group (n=24): 75% female, 25% male
- Status — Participants were recruited from the Child Anxiety and Depression Clinic
at Babies Hospital Columbia Presbyterian Medical Center, New York, NY,
and the clinical Research Center, New York State Psychiatric Institute,
New York, between 1993 and 1996. Most patients were self-referred or
referred by parents or mental health professionals from school-based
clinics. All participants met the criteria for Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) major depressive disorder.
Location / Institution: New York
Summary: (To include comparison groups, outcomes, measures, notable limitations)
In a 12-week clinical trial of Interpersonal Psychotherapy for Depressed Adolescents (IPT-A), clinic-referred adolescents were randomly assigned to either weekly IPT-Aor
clinical monitoring. Measures to diagnose and assess depression
symptoms, global and social functioning, and problem-solving skills
included the Diagnostic Interview Schedule for Children Version 2.3 (DISC 2.3), Schedule for Affective Disorders and Schizophrenia for School-Aged Children (K-SADS-E), Hamilton Rating Scale for Depression (HRSD), Beck Depression Inventory (BDI), and Children’s Global Assessment Scale (C-GAS). Patients who received IPT-A
reported a notably greater decrease in depressive symptoms and greater
improvement in overall social functioning, functioning with friends, and
specific problem-solving skills. Limitations of the study include the
small sample size, predominantly Latino and low socioeconomic status
sample, and the lack of follow-up data.
Length of post-intervention follow-up: None.

Type of Study: Randomized controlled trial
Number of Participants: 71
Population:
- Age range — 13-17 years
- Race/Ethnicity — Not Specified
- Gender — 54% female, 46% male
- Status — All adolescents in the study were referred to the clinic by local
schools after members of the research team visited schools in the area
and presented the project to principals and social workers.
Location / Institution: Centro Universitario de Servicios y Estudios Psicologicos (University Center for Psychological Services and Research) at University of Puerto Rico.
Summary: (To include comparison groups, outcomes, measures, notable limitations)
Participants were randomly assigned to 1 of 3 conditions:
cognitive-behavioral therapy (CBT), Interpersonal Psychotherapy (IPT),
or wait list (WL). In order to assess a wide range of depressive
symptoms, the Child Depression Inventory (CDI) was used. Additional measures included the Piers-Harris Children’s Self-Concept Scale (PHCSCS), the Social Adjustment Scale for Children and Adolescents (SASCA), which measures the social adjustment by taking into account interpersonal and school functioning, the Family Emotional Involvement and Criticism Scale (FEICS), as well as the Child Behavior Checklist (CBCL),
which assesses social abilities and behavior problems in children and
adolescents. Results showed that both IPT and CBT significantly reduced
depressive symptoms and increased self-esteem when compared with the WL
condition. At posttreatment, it was found that 82% of those in IPT and
59% of those in CBT showed a clinically significant change. Limitations
of the study include the small sample size and the primary use of
self-report measures.
Length of post-intervention follow-up: 3 months.

Type of Study: Randomized controlled trial
Number of Participants: 63
Population:
- Age range — 12-18 years
- Race/Ethnicity — 71% Hispanic
- Gender — 84% female, 16% male
- Status — Participants were referred to mental health clinicians in 1 of 5
school-based health clinics (3 middle schools and 2 high schools)
within schools located in urban, impoverished areas of New York City.
Location / Institution: Five school-based mental health clinics in New York City
Summary: (To include comparison groups, outcomes, measures, notable limitations)
This study assessed the effectiveness of Interpersonal Psychotherapy for Depressed Adolescents (IPT-A) compared with treatment as usual (TAU) in school-based mental health clinics. Participants were randomly assigned to receive IPT-A (n=34) or TAU (n=29) from school-based health clinic clinicians. Measures used to assess depression symptoms included the Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI); the Children’s Global Assessment Scale (C-GAS), and Clinical Global Impressions (CGI) scale measured global functioning; and the Social Adjustment Scale – Self-Report (SAS-SR) assessed social functioning. Adolescents treated with IPT-A compared with TAU showed greater symptom reduction and improvement in overall functioning. Compared with the TAU group, the IPT-A group showed significantly fewer clinician-reported depression symptoms on the HAMD and BDI, significantly better functioning on the C-GAS, significantly better overall social functioning on the SAS-SR, and significantly greater clinical improvement and significantly greater decrease in clinical severity on the CGI
scale. Limitations of the study include the small sample size &
questionable generalizability of the predominantly female & Hispanic
sample.
Length of post-intervention follow-up: 1 month or less.

adolescent depression: IPT-A versus treatment as usual in school-based
health clinics. Journal of Consulting & Clinical Psychology, 78(2), 260-667.
Type of Study: Randomized controlled trial
Number of Participants: 63
Population:
- Age range — 12-18 years
- Race/Ethnicity — 74.6% Latino, 14.3% African American, 1.6% Asian American, 9.5% other
- Gender — 84.1% female, 15.9% male
- Status — Adolescents were referred for mental health treatment in five
school-based health clinics in New York City, and each had a diagnosis
of major depression, dysthymia, depressive disorder not otherwise
specified, or adjustment disorder with depressed mood.
Location / Institution: Columbia University College of Physicians and Surgeons; New York State Psychiatric Institute
Summary: (To include comparison groups, outcomes, measures, notable limitations)
Participants were randomly assigned to receive Interpersonal Psychotherapy for Depressed Adolescents (IPT-A)
or treatment as usual (TAU) delivered by school-based mental health
clinicians. In order to assess current, past, and lifetime diagnostic
status of psychopathology for children and adolescents on the basis of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) diagnostic criteria, the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) was administered. Other measures to assess perceived interpersonal functioning included the Hamilton Rating Scale for Depression (HRSD), which is a semi-structured interview developed to assess the severity of depression symptoms, the Conflict Behavior Questionnaire (CBQ-20), which is a self-report measure to assess parent-child communication and conflict style, and the Social Adjustment Scale – Self-Report (SAS-SR),
which assesses social functioning in the following categories: friends,
school, family, and dating. As hypothesized, adolescents treated with IPT-A
showed greater and more rapid reductions in depression symptoms, as
compared with participants treated with TAU. Results showed that the
benefits of IPT-A over TAU were particularly
strong for the adolescents who reported high baseline levels of conflict
with their mothers and social dysfunction with friends. Limitations of
the study include the small sample size and questionable
generalizability of a sample primarily consisting of low-income Hispanic
females, as well as the lack of follow-up data.
Length of post-intervention follow-up: None (aside from 1 month follow-up telephone interview).
