RESUMO
OBJECTIVES: The Patient Health Questionnaire-9 Modified (PHQ-9M) is a self-report tool used to assess the presence and severity of depressive symptoms in teenagers. Despite widespread use in primary care clinics and psychiatric settings, the PHQ-9M has not been validated nor are its psychometric properties adequately understood for the adolescent population. This study sought to examine the psychometrics of the PHQ-9M in treatment-seeking, depressed adolescents at a psychiatric psychopharmacology clinic who were concurrently assessed with the Children's Depression Rating Scale Revised (CDRS-R) and Quick Inventory of Depressive Symptomatology-Adolescent (17-item) Self-Report (QIDS-A17-SR). METHODS: Adolescents (N = 160) aged 13 through 18 years with a diagnosis of major depressive disorder, determined on the basis of a clinical interview and semi-structured interview using the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version, were assessed for severity of depressive symptoms with the PHQ-9M, CDRS-R (adolescent interview only), and QIDS-A17-SR assessments at baseline, 4, and 8 weeks. Classical test theory analysis was used to evaluate the internal consistency and dimensionality of the PHQ-9M. Convergent validity was evaluated via intraclass correlations of the PHQ-9M with the CDRS-R and QIDS-A17-SR. Sensitivity to treatment response was also evaluated. RESULTS: The internal consistency (Cronbach's coefficient α) at baseline, 4, and 8 weeks was 0.879, 0.859, and 0.827 for the PHQ-9M; 0.739, 0.835, and 0.867 for CDRS-R; and 0.712, 0.777, and 0.804 for QIDS-A17-SR, respectively. The PHQ-9M had moderate convergent validity with the CDRS-R but good convergent validity with the QIDS-A17-SR. The PHQ-9M was less sensitive to changes in symptom severity than the CDRS-R and QIDS-A17-SR. CONCLUSIONS: The PHQ-9M appears to be a valid and reliable assessment tool for the severity of depressive symptoms in a psychiatric clinic setting. However, its utility as a treatment outcome measure may be limited compared with other available rating scales.

OBJECTIVE: Collaborative care models for treatment of adolescent depression are rapidly evolving. However, a dearth of information exists regarding patient characteristics associated with positive outcomes. We explored the association between baseline scores on routine screening tools for substance abuse, mood disorders, and anxiety with depression remission and graduation from a collaborative care program in an outpatient pediatric practice. METHODS: Adolescents (aged 12-17 years) with Patient Health Questionnaire-9 Modified for Adolescents (PHQ-9A) score ≥ 10 and a diagnosis of depressive disorder based on DSM-IV criteria between July 2011 and August 2015 were eligible for enrollment in a collaborative care model and inclusion in this study. Remission was defined as a single PHQ-9A score < 5; the criterion for graduation was 3 consecutive months with PHQ-9A score < 5. Analyses compared baseline assessment scores with those at remission and graduation. RESULTS: Of the 182 patients included in the analysis, the overall remission rate was 55%; program graduation rate was 27%. There was no association between scores on baseline screening tools and remission. Graduation was associated with lower scores on a screening tool for substance abuse (unit odds ratio [OR] = 1.62; P = .01) and anxiety (unit OR = 1.03; P = .02). When the scores were examined as categorical variables, graduation was associated with negative assessments on screening tools for substance abuse (OR = 3.21; P = .003) and anxiety (OR = 2.35; P = .02). CONCLUSIONS: Baseline substance abuse and anxiety assessments may have utility in identifying depressed adolescents who are less likely to maintain remission and graduate from a collaborative care program, suggesting that these patients may need additional intervention to achieve sustained remission.

OBJECTIVE: Depression is common among adolescents, but many lack ready access to mental health services. Integrated models of care for depression are needed, along with evidence to support their use in regular practice. The authors examined the effectiveness of an ongoing collaborative care program for depressed adolescents embedded in a busy primary care practice. METHODS: This retrospective cohort study assessed EMERALD (Early Management and Evidence-based Recognition of Adolescents Living with Depression), a collaborative care program. All patients ages 12-17 and age 18 and still in high school with a score of ≥10 on the nine-item Patient Health Questionnaire for Adolescents (PHQ-9A) and without a diagnosis of bipolar disorder were eligible. The sample included 162 EMERALD participants and 499 similarly eligible non-EMERALD patients. Outcomes were six-month remission of depression (score <5) and six-month treatment response (>50% reduction from baseline) as measured by the PHQ-9A. Analyses included logistic regression and propensity score matching to adjust for differences in demographic factors and number of contacts-observations. RESULTS: After propensity score matching, EMERALD patients had better adjusted rates of depression remission (11 percentage points higher, p=.035) and treatment response (14 percentage points higher, p<.001) than comparison patients. Results from primary analyses were as conservative as or more conservative than results from all sensitivity analyses tested. CONCLUSIONS: Collaborative care for adolescents in regular practice led to better remission and treatment response than usual care. Future studies could examine which groups might benefit most and flexible payment models to support these services.

OBJECTIVE: Clinical reviews of practice outcomes of adolescent patients who have received electroconvulsive therapy (ECT) remain relatively rare. This study reports the clinic practice and outcome of adolescents receiving ECT at a tertiary medical center. METHODS: From April 1991 through November 2013, 51 adolescents (30 female; mean [SD] age, 16.8 [1.6] years) received ECT. The electronic medical record at the time of the first ECT session was reviewed for the clinical diagnosis, ECT lead placement and general administration, seizure duration, adverse effects, concurrent medications, and clinical outcome. RESULTS: ECT was recommended for primary mood and psychotic disorders or catatonia. Patients received a mean (SD) of 9.3 (3.5) treatments, with initial bitemporal lead placement in 36 patients (71%). Thirty-nine patients (77%) were much or very much improved based on Clinical Global Impressions-Improvement scale at the end of the acute treatment. Prolonged seizure duration (>120 seconds) was relatively common (63%) but appeared to decrease in older patients. CONCLUSIONS: This report describes the largest group of adolescents receiving ECT since 1947, and supports ECT as a safe and effective modality for most treatment-recalcitrant psychiatric illness in youth.

OBJECTIVES: The objective of this post-hoc exploratory analysis was to examine the relationship between age and measures of cortical excitability and inhibition. METHODS: Forty-six participants (24 with major depressive disorder and 22 healthy controls) completed MT, SICI, ICF, and CSP testing in a cross-sectional protocol. Of these 46 participants, 33 completed LICI testing. Multiple linear robust regression and Spearman partial correlation coefficient were used to examine the relationship between age and the TMS measures. RESULTS: In the overall sample of 46 participants, age had a significant negative relationship with motor threshold (MT) in both the right (r s = -0.49, adjusted p = 0.007; ß = -0.08, adjusted p = 0.001) and left (r s = -0.42, adjusted p = 0.029; ß = -0.05, adjusted p = 0.004) hemispheres. This significant negative relationship of age with MT was also observed in the sample of depressed youth in both the right (r s = -0.70, adjusted p = 0.002; ß = -0.09, adjusted p = 0.001) and left (r s = -0.54, adjusted p = 0.034; ß = -0.05, adjusted p = 0.017) hemispheres, but not in healthy controls. In the sample of the 33 participants who completed LICI testing, age had a significant negative relationship with LICI (200 ms interval) in both the right (r s = -0.48, adjusted p = 0.05; ß = -0.24, adjusted p = 0.007) and left (r s = -0.64, adjusted p = 0.002; ß = -0.23, adjusted p = 0.001) hemispheres. This negative relationship between age and LICI (200 ms interval) was also observed in depressed youth in both the right (r s = -0.76, adjusted p = 0.034; ß = -0.35, adjusted p = 0.004) and left (r s = -0.92, adjusted p = 0.002; ß = -0.25, adjusted p = 0.001) hemispheres. CONCLUSION: These findings suggest that younger children have higher MTs. This is more pronounced in depressed youth than healthy controls. LICI inhibition may also increase with age in youth.
