Interpersonal psychotherapy (IPT) and drugs in the treatment of depression

IPT is a brief form of psychotherapy, developed specifically for treatment of depression. It is based on the theoretical writings of Meyer and Sullivan and empirical research from epidemiology and clinical investigations. The efficacy of IPT for ambulatory depressive has been established in three controlled studies, two conducted by the investigators and one conducted by the National Institute of Mental Health.     

The value of maintenance interpersonal psychotherapy (IPT) in older adults with different IPT foci.

OBJECTIVE/METHODS: The authors examined recurrence rates of major depression in elderly subjects with different foci of interpersonal psychotherapy (IPT), who were treated for up to 3 years with either monthly maintenance IPT and pill placebo or with monthly clinical management and pill placebo. RESULTS: Among subjects with an IPT focus on role conflict, a greater proportion of those treated with maintenance-IPT survived for 3 years without recurrence than those treated with placebo/clinical management. Median time to recurrence was 68.9 weeks in IPT-treated patients versus 16.3 weeks for patients in clinical management. Subjects with an IPT focus on abnormal grief or role transition demonstrated no effect differential for maintenance IPT and pill-placebo on recurrence prevention over supportive clinical management and pill-placebo. CONCLUSION: If replicated in a larger sample, these findings have important implications for ongoing case-management decisions.     

Using interpersonal therapy (IPT) with older adults today and tomorrow: A review of the literature and new developments

Interpersonal psychotherapy (IPT) has been shown to be an efficacious evidence-based treatment for major depression in combination with antidepressant medication, as a maintenance treatment in combination with medication, and as monotherapy (with placebo). After reviewing the salient features of IPT that make it a good fit for treating older patients, I summarize the extant literature. New adaptations of IPT for depressed older adults with cognitive impairment are delineated. An argument is articulated for why IPT may be the ideal psychotherapy for older patients.     

The utility of biological monitoring for manganese in ferroalloy smelter workers in South Africa

Five hundred and nine workers at a manganese (Mn) smelting works comprising eight production facilities and 67 external controls were studied cross-sectionally. Exposure measures from personal sampling included inhalable dust, cumulative exposure indices (CEI) and average intensity (INT = CEI/years exposed) calculated for the current job at the smelter and also across all jobs held by subjects. Biological exposure was measured by Mn in the blood (MnB) and urine (MnU) and biological effect was measured by serum prolactin. Average lifetime exposure intensity across all jobs ranged from near 0 (0.06 microg/m3) for unexposed external referents to 5 mg/m3. Atmospheric exposures and MnB and MnU distributions were consistent with published data for both unexposed and smelter workers. Associations between biological exposures and groups defined by atmospheric exposures in the current job were substantial for MnB, less so for MnU and absent for serum prolactin. Random sampling of MnB measurements representative of a group of workers with more than 1-2 years of service in the same job and notionally homogenous exposure conditions could serve as a cross-sectional predictor of atmospheric Mn exposure in the current job, as well as for surveillance of Mn exposure trends over time. Correlations at the individual level were only modest for MnB (33% of the variance in log atmospheric Mn intensity in the current job was explained by log MnB), much worse for MnU (only 7%). However, a receiver operating characteristic (ROC) analysis was performed which showed that it is possible to use a MnB cut-off of 10 microg/l (the 95th percentile in the unexposed) to good effect as a screening tool to discriminate between individual exposures exceeding and falling below a relatively strict atmospheric Mn exposure threshold at the ACGIH threshold limit value (TLV) of 0.2 mg/m3. MnU has no utility as a measure of biological exposure nor does serum prolactin as a measure of biological effect.     

Methods of testing feasibility for sequenced treatment alternatives to relieve depression (STAR*D)

In large multi-site trials, a feasibility or pilot study can be crucial to test the functionality of all aspects of conducting the study prior to the initiation of the formal study. A feasibility trial was conducted for the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) Project, a multi-site, prospective, sequentially randomized, clinical trial of outpatients with nonpsychotic major depressive disorder. From 14 December 2000 to 8 June 2001, 42 patients were screened for enrollment into the STAR*D Feasibility Trial. Twenty-four patients who were eligible and consented to participate were treated with citalopram for up to 12 weeks. During the course of this trial, issues were raised that resulted in modifications to the study procedures. Modifications made as a result of this trial affected four domains: (1) communication, (2) patient and provider burden, (3) data collection forms, and (4) recruitment and retention of subjects. This paper describes what was learned during the STAR*D Feasibility Trial so researchers planning to conduct similar trials can learn the practical issues related to conducting such a research project. While the information gathered was useful, it did delay the initiation of the formal trial. We view this cost as an investment in the development of overall study procedures that should lead to a stronger study.     

The development of a brief psychodynamic intervention (dynamic interpersonal therapy) and its application to depression: a pilot study

This paper describes a protocol for a brief psychodynamic intervention (Dynamic Interpersonal Therapy; DIT) for use with depressed patients and a pilot study set out to test its acceptability and compatibility with session-by-session monitoring as a prelude to a future randomized controlled trial. Sixteen consecutively referred, depressed patients (aged 20-53) were offered 16 sessions of DIT. Patient outcomes were collected pre-post, and on a session-by-session basis, using the PHQ-9 and GAD-7. Therapist and supervision feedback indicates that this structured psychodynamic treatment could be effectively taught, and that the key competences involved were acquired and demonstrated in the clinical work supervised. Patients found the treatment acceptable and relevant to their problems. The treatment appeared compatible with session-by-session monitoring of symptoms of anxiety and depression. DIT was associated with a significant reduction in reported symptoms in all but one case, to below clinical levels in 70% of the patients. Random regression models revealed highly significant linear and quadratic components, confirming the decrease in reported symptom severity but cautioning about slight increase in symptoms around the ending phase of the treatment. The results suggest that DIT is promising in its acceptability and effectiveness with an unselected group of primary care patients, and is easily acquired by psychodynamically trained clinicians.     

Supportive-expressive dynamic psychotherapy in the community mental health system: A pilot effectiveness trial for the treatment of depression

The goal of the current article is to present the results of a randomized pilot investigation of a brief dynamic psychotherapy compared with treatment-as-usual (TAU) in the treatment of moderate-to-severe depression in the community mental health system. Forty patients seeking services for moderate-to-severe depression in the community mental health system were randomized to 12 weeks of psychotherapy, with either a community therapist trained in brief dynamic psychotherapy or a TAU therapist. Results indicated that blind judges could discriminate the dynamic sessions from the TAU sessions on adherence to dynamic interventions. The results indicate moderate-to-large effect sizes in favor of the dynamic psychotherapy over the TAU therapy in the treatment of depression. The Behavior and Symptom Identification Scale-24 showed that 50% of patients treated with dynamic therapy moved into a normative range compared with only 29% of patients treated with TAU.

The feasibility of psychomotor therapy in acute mental health services for adults with intellectual disability

Background Psychomotor therapy enables people to reflect on the relationship between experiences and feelings by starting from awareness of bodily responses rather than from awareness of emotion. In this study we examine PsyMot (ID), an assessment that directs this psychological therapy.

Method Twelve suitable consecutive admissions were recruited from a specialist intellectual disability (ID) assessment and treatment unit for adults. Video-recordings of PsyMot (ID) allowed assessment of interrater reliability (IRR). Treatment goals indicated by PsyMot (ID) were addressed using psychomotor therapy as part of a comprehensive program of interventions.

Results Psychomotor therapy was both feasible and popular with patients who participated without any adverse effects. Nine patients completed PsyMot (ID). IRR of the treatment goals identified by all 3 raters was good to excellent in 81% cases, but there were discrepancies for individual items.

Conclusions PsyMot (ID) and psychomotor therapy is feasible within this context, and enriched the clinical team's formulation. Further studies of reliability and efficacy should be undertaken.     

Validity of the patient health questionnaire-9 for depression screening and diagnosis in East Africa

Depression is often underdiagnosed and undertreated in primary care settings, particularly in developing countries. This is, in part, due to challenges resulting from lack of skilled mental health workers, stigma associated with mental illness, and lack of cross-culturally validated screening instruments. We conducted this study to evaluate the reliability and validity of the Patient Health Questionnaire-9 (PHQ-9) as a screen for diagnosing major depressive disorder among adults in Ethiopia, the second most populous country in sub-Saharan Africa. A total of 926 adults attending outpatient departments in a major referral hospital in Ethiopia participated in this study. We assessed criterion validity and performance characteristics against an independent, blinded, and psychiatrist administered semi-structured Schedules for Clinical Assessment in Neuropsychiatry (SCAN) interview. Overall, the PHQ-9 items showed good internal (Cronbach's alpha=0.81) and test re-test reliability (intraclass correlation coefficient=0.92). A factor analysis confirmed a one-factor structure. Receiver Operating Characteristics (ROC) analysis showed that a PHQ-9 threshold score of 10 offered optimal discriminatory power with respect to diagnosis of major depressive disorder via the clinical interview (sensitivity=86% and specificity=67%). The PHQ-9 appears to be a reliable and valid instrument that may be used to diagnose major depressive disorders among Ethiopian adults.     

The use of referenced-EEG (rEEG) in assisting medication selection for the treatment of depression

Objective

To evaluate the efficacy of rEEG^®-guided pharmacotherapy for the treatment of depression in those circumstances where rEEG and STAR*D provided different recommendations.

Materials and methods

This was a randomized, single-blind, parallel group, 12 center, US study of rEEG-guided pharmacotherapy vs. the most effective treatment regimens reported in the NIH sponsored STAR*D study. Relatively treatment-resistant subjects ≥18 years who failed one or more antidepressants were required to have a QIDS-16-SR score ≥13 and a MADRS score ≥26 at baseline. All subjects underwent a washout of all current medications (with some protocol-specified exceptions) for at least five half-lives before receiving a QEEG and rEEG report. Subjects randomized to rEEG were assigned a regimen based on the rEEG report. Control subjects who had failed only SSRI’s in their current episode were randomized to receive venlafaxine XR. Control subjects who had failed antidepressants from ≥2 classes of antidepressants were randomized to receive a regimen from Steps 2-4 of the STAR*D study. Treatment lasted 12 weeks. The primary outcome measures were change from baseline for self-rated QIDS-SR16 and Q-LES-Q-SF.

Results

A total of 114 subjects were randomized and 89 subjects were evaluable. rEEG-guided pharmacotherapy exhibited significantly greater improvement for both primary endpoints, QIDS-SR16 (−6.8 vs. −4.5, p < 0.0002) and Q-LES-Q-SF (18.0 vs. 8.9, p < 0.0002) compared to control, respectively, as well as statistical superiority in 9 out of 12 secondary endpoints.

Conclusions

These results warrant additional studies to determine the role of rEEG-guided psychopharmacology in the treatment of depression. If these results were confirmed, rEEG-guided pharmacotherapy would represent an easy, relatively inexpensive, predictive, objective office procedure that builds upon clinical judgment to guide antidepressant medication choice.     

Transcultural issues in the dynamics of a Balint clinical reflection group for community mental health workers

The author presents transcultural issues in the content, process, and group dynamics of consecutive meetings of a Balint clinical reflection group for community mental health workers at Inala, Australia. Balint work and the context and evolution of the group process are briefly described, as is the consultative research methodology. The process of a Balint group meeting is reported in detail, following the author's consultation with group members. The collaborative work of a culturally diverse team of mental health professionals is examined in the context of discussion of a practitioner-patient relationship in which transcultural, gender, and family conflicts were the focus of affective and cognitive dissonance. For mental health workers engaging with communities of cultural diversity, Balint reflection groups can facilitate insight into cultural countertransferences that adversely affect clinical work. The group served to support the caseworkers' engagement with patients of different cultures, and provided a safe environment for the creative consideration and exploration in fantasy of the emotional pressures and complex ethical dilemmas related to boundaries in transcultural client-practitioner relationships, including those in which open discussion would otherwise be avoided.     

Predictors of the duration of therapy for clients in the community mental health system

Single and multiple correlates for premature termination and duration of treatment were examined for 13,450 clients seem in 17 community mental health facilities. Predictor variables included seven demographic characteristics of clients and five characteristics of service (type of personnel seeing clients, assignment to inor outpatient programs, diagnosis rendered, assignment to therapy or diagnostic services, and assignment to individual therapy or other services). Results indicated that clients who are members of ethnic groups, who have low educational backgrounds, who are seen by paraprofessional staff, and who are assigned for diagnostic services quickly terminate at community mental health facilities.The research for this project was supported by Research Grant MH22090-01 from the National Institute of Mental Health with the cooperation of the Department of Social and Health Services, State of Washington.
