Implementation of an acceptance- and mindfulness-based group for depression and anxiety in primary care: Initial outcomes

INTRODUCTION

Depression and anxiety disorders are highly prevalent among primary care patients. Group visits provide a way of delivering interventions to multiple patients at the same time. Group visits for depression and anxiety present an opportunity to expand the reach of behavioral health services for primary care patients. The goal of the current study was to evaluate the implementation of an acceptance and mindfulness-based group for primary care patients with depression and anxiety.

METHODS

Adult family medicine patients with Patient Health Questionnaire-9 (PHQ-9) and/or Generalized Anxiety Disorder Scale-7 (GAD-7) scores > 5 were eligible for the group. The group was held biweekly in the family medicine practice with rolling enrollment. The PHQ-9 and GAD-7 were administered at every visit, and changes in depression and anxiety symptoms were analyzed using multilevel modeling. We evaluated feasibility, acceptability/satisfaction, penetration, and sustainability.

RESULTS

Over the course of 19 months, 50 patients were referred to the group, and 29 enrolled. The median number of visits attended was four among those who attended more than one group visit. Results revealed that depression and anxiety symptoms decreased significantly over the first four visits attended (d = -.26 and -.19, respectively). Patients who attended more than one group reported high satisfaction. The group was sustainable after the research funding ended; however, penetration was low.

DISCUSSION

A rolling enrollment group for patients with depression and anxiety that utilized mindfulness- and acceptance-based treatment principles is feasible to implement in a primary care setting but is not without challenges. Recommendations for ways to enhance implementation and future research are provided. (PsycINFO Database Record

Pilot Randomized Trial of Collaborative Behavioral Treatment for Chronic Pain and Depression in Persons Living with HIV/AIDS

In this pilot study, we assessed feasibility and acceptability of a behavior therapy intervention for pain and depressive symptoms in persons living with HIV/AIDS (PLWH). We randomly assigned 23 participants to HIV-PASS (HIV-Pain and Sadness Study) or a health education control arm for 3 months. On average, participants attended more than 5 sessions (of 7 possible) in both arms. Qualitative data suggest HIV-PASS participants understood key messages and made concrete behavioral changes. HIV-PASS was associated with effects in the expected direction for three of four outcomes, including the primary outcome (pain-related interference with functioning). Findings suggest that HIV-PASS is promising.

Differential endorsement of suicidal ideation and attempt in bipolar versus unipolar depression: a testlet response theory analysis

BACKGROUND

Published data concerning differences in suicide risk across the mood disorders spectrum remain mixed. The current study used testlet response theory methods to evaluate differences in the endorsement of suicidal ideation and attempt in an epidemiological sample of individuals with bipolar and unipolar depression.

METHOD

Participants with lifetime history of bipolar I (n=1154), bipolar II (n=494), and unipolar (n=5695) depression were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions, which included 4 structured queries concerning suicidal ideation/attempt. We estimated differential item functioning between groups with a 2-pl parametric item response model.

RESULTS

Endorsement of suicide items increased as a function of underlying depression severity. Equating for severity, endorsement of suicidal ideation and attempt was generally more frequent in bipolar versus unipolar depression, and in bipolar I versus bipolar II depression. Yet findings were not consistent across all suicide items, and differences were small in magnitude.

LIMITATIONS

The NESARC relied upon lifetime endorsement of suicide items, and suicide risk was only evaluated within the context of a major depressive episode. Thus, this study could not evaluate endorsement of suicide items within the context of (hypo)manic or mixed states.

CONCLUSION

Although there were some group differences, patterns of item endorsement were more similar than different. These data support a transdiagnostic model of suicide that emphasizes underlying depression severity over mood disorder class.

Patients' Beliefs About Medications are Associated with Stated Preference for Methadone, Buprenorphine, Naltrexone, or no Medication-Assisted Therapy Following Inpatient Opioid Detoxification

Subsequent to initial opioid detoxification, people with opioid use disorder are typically advised to engage in follow-up treatment to prevent relapse. Medication-assisted treatments (MATs) - i.e., the opioid agonist methadone (MMT) or partial agonist/antagonist, buprenorphine/naltrexone (BUP) -- are the maintenance treatment options with the best research support for positive outcomes. A third MAT, injectable extended-release naltrexone (XR-NTX), was approved by the FDA for opioid dependence in 2010 and shows promise. However, relatively few eligible patients choose to initiate one of these MATs following initial detoxification treatment. Consistent with the health belief model, we hypothesized that beliefs about 1) efficacy of each MAT; 2) safety of each MAT; and 3) perceived consistency with being drug-free would predict stated patient preferences for a particular MAT or for no MAT. We also hypothesized that perceived structural barriers (e.g., time, transportation) would decrease the likelihood of stating a preference for a given MAT. To assess these hypotheses, we surveyed 372 people undergoing inpatient opioid detoxification treatment. Results supported hypotheses for all 3 sets of patient beliefs, with the patient group stating that they preferred a particular MAT having significantly more positive beliefs about that MAT relative to other groups (p<.001). The group that preferred "no MAT" had the most negative beliefs about all MATs. Perceived structural barriers were not related to stated preferences, except that people who preferred BUP were more likely to endorse barriers to MMT than any of the other 3 groups. Notably, a relatively high proportion (32%) of participants were most interested in XR-NTX despite a lack of prior experience with this medication. These results suggest that efforts to increase MAT enrollment following detoxification might benefit from including patient beliefs as one set of factors to assess and target for change.

Yoga for Depression and Anxiety: A Review of Published Research and Implications for Healthcare Providers

There is increasing interest in the use of yoga as way to manage or treat depression and anxiety. Yoga is afford- able, appealing, and accessible for many people, and there are plausible cognitive/affective and biologic mechanisms by which yoga could have a positive impact on depression and anxiety. There is indeed preliminary evidence that yoga may be helpful for these problems, and there are several ongoing larger-scale randomized clinical trials. The current evidence base is strongest for yoga as efficacious in reducing symptoms of unipolar depression. However, there may be risks to engaging in yoga as well. Healthcare providers can help patients evaluate whether a particular community-based yoga class is helpful and safe for them.

Clinical characteristics and medication use patterns among hospitalized patients admitted with psychotic vs nonpsychotic major depressive disorder

BACKGROUND

In routine practice, major depressive disorder (MDD) with psychotic features often goes under-recognized and undertreated. Previous research has specified several demographic and clinical differences in MDD patients with psychotic features compared with those without psychosis in routine outpatient practice, but there is little systematic research in modern routine hospital settings.

METHODS

We conducted a retrospective electronic medical records chart review of 1,314 patients diagnosed with MDD who were admitted consecutively to a major psychiatric hospital over a 1-year period. We examined the prevalence of psychotic features in the sample and investigated the differences in demographic variables, clinical characteristics, and medication use patterns among patients with and without psychosis.

RESULTS

The prevalence of psychotic features was 13.2% in the current hospital sample. Patients with psychotic depression were more likely to be older, male, a member of a racial/ethnic minority, and have more medical comorbidities and certain Axis I disorders compared with nonpsychotic patients. In addition, patients with psychotic depression were more likely to be prescribed antipsychotics and hypnotics before admission.

CONCLUSIONS

Several demographic and clinical characteristics differentiate MDD patients with psychosis from those without psychosis in hospital settings that may be helpful in identifying these patients. Comparisons with outpatient samples and treatments implications are discussed.

Chronic Pain in HIV-Infected Patients: Relationship to Depression, Substance Use, and Mental Health and Pain Treatment

OBJECTIVE

As the advent of highly active antiretroviral therapy, HIV has become a chronic disease for most individuals in developed countries. Chronic pain is a common occurrence for HIV-infected patients and has an impact on quality of life and antiretroviral adherence. The objective of this study was to examine relationships between chronic pain and depression, substance use, mental health treatment, and pain treatment in HIV-infected patients.

DESIGN

Cross-sectional study.

SETTING

Three primary care sites where HIV+ patients receive treatment.

SUBJECTS

Two hundred and thirty eight HIV-infected primary care patients.

METHODS

We collected self-report and chart-review information on demographics, HIV clinical status, chronic pain, depression, substance use, mental health treatment, and pain treatment. We collected data between October 2012 and November 2013.

RESULTS

Of the patients enrolled in this study, 107 reported no chronic pain, 24 reported mild chronic pain, and 107 reported moderate-severe chronic pain. Participants in the moderate-severe pain group were more likely to have high levels of depressive symptoms than those in the no chronic pain group. Similarly, there was a significant relationship between chronic pain status and interference with life activities due to pain. Participants with moderate-severe chronic pain were more likely to be taking an antidepressant medication than those with mild chronic pain, and more likely to be taking a prescription opioid than the other two groups. We did not find a significant relationship between problematic substance use and chronic pain status.

CONCLUSIONS

Despite pharmacologic treatment, moderate-severe chronic pain and elevated depression symptoms are common among HIV-infected patients and frequently co-occur.

Physician actions following a positive PHQ-2: implications for the implementation of depression screening in family medicine practice

Systematic screening of depression in primary care settings that have adequate follow-up and treatment is recommended. The Patient Health Questionnaire (PHQ-9) was developed as a depression screening measure for use in primary care. The PHQ-2, which includes just 2 items from the PHQ-9, is designed to be used as a first line depression screening measure, to be followed by the full PHQ-9 when a patient screens positive. However, completion of the first step in the process (PHQ-2) does not necessarily lead to completion of the second step (administration of the PHQ-9 when the PHQ-2 is positive), even when treatment and follow-up are available. The objective of the current study was to describe family medicine physicians' actions following a positive PHQ-2 and factors that affect their use of depression screening measures and treatment decisions. A retrospective chart review of 200 family medicine patients who screened positive on the PHQ-2 during an office visit was conducted. Additionally, 26 family medicine physicians in the practice were surveyed. Only 5% of patients with positive PHQ-2 scores were administered a PHQ-9. Physicians relied on their clinical judgment and prior knowledge about the patient's depression status to inform treatment decisions and cited time constraints and competing demands as reasons for not administered the PHQ-9. Physicians tended to treat depression with adequate doses of antidepressants and counseling. PHQ-2 screening did not necessarily lead to further evaluation, systematic follow-up, or changes in treatment. Implications for the implementation of depression screening in primary care settings are discussed.

Social support and physical activity as moderators of life stress in predicting baseline depression and change in depression over time in the Women's Health Initiative

PURPOSE

To determine whether social support and/or physical activity buffer the association between stressors and increasing risk of depression symptoms at baseline and at 3-year follow-up.

METHODS

This is a secondary analysis of data from the Women's Health Initiative Observational Study. 91,912 community-dwelling post-menopausal women participated in this prospective cohort study. Depression symptoms were measured at baseline and 3 years later; social support, physical activity, and stressors were measured at baseline.

RESULTS

Stressors at baseline, including verbal abuse, physical abuse, caregiving, social strain, negative life events, financial stress, low income, acute pain, and a greater number of chronic medical conditions, were all associated with higher levels of depression symptoms at baseline and new onset elevated symptoms at 3-year follow-up. Social support and physical activity were associated with lower levels of depressive symptoms. Contrary to expectation, more social support at baseline strengthened the association between concurrent depression and physical abuse, social strain, caregiving, and low income. Similarly, more social support at baseline increased the association between financial stress, income, and pain on new onset depression 3 years later. Physical activity similarly moderated the effect of caregiving, income, and pain on depression symptoms at baseline.

CONCLUSION

Stressors, social support, and physical activity showed predicted main effect associations with depression. Multiplicative interactions were small in magnitude and in the opposite direction of what was expected.

Prospective study of risk factors for suicidal behavior in individuals with anxiety disorders

BACKGROUND

Anxiety disorders are very common and increase risk for suicide attempts. Little is known about predictors of increased risk specifically among individuals with anxiety disorders. The purpose of this study was to investigate whether specific anxiety disorders and other co-morbid psychiatric disorders, physical health, or work or social functioning increased the future likelihood of a suicide attempts among individuals with anxiety disorders. Method In this prospective study, 676 individuals with an anxiety disorder were followed for an average of 12 years.

RESULTS

As hypothesized, we found that post-traumatic stress disorder, major depressive disorder (MDD), intermittent depressive disorder (IDD), epilepsy, pain, and poor work and social functioning all predicted a shorter time to a suicide attempt in univariate analyses. In multivariate analyses, baseline MDD and IDD were independent predictors of time to suicide attempt, even when controlling for a past history of suicide attempt. No specific anxiety disorder was an independent predictor of time to attempt in this anxiety-disordered sample. Adding baseline physical health variables and social functioning did not improve the ability of the model to predict time to suicide attempt.

CONCLUSIONS

Mood disorders and past history of suicide attempts are the most powerful predictors of a future suicide attempt in this sample of individuals, all of whom have an anxiety disorder.

Patient health questionnaire depression scale as a suicide screening instrument in depressed primary care patients: a cross-sectional study

OBJECTIVE

The aim of this study was to examine the sensitivity and specificity of the suicide item on the 9-item Patient Health Questionnaire (PHQ-9) when compared to a structured interview (the Structured Clinical Interview for DSM-IV; SCID-I mood module) in primary care patients with elevated depression symptoms.

METHOD

In this cross-sectional study, we analyzed data from 166 patients from 2 primary care clinics, 1 in Rhode Island and 1 in Massachusetts, who were enrolled in studies that focused on depression in primary care. Of the total participants, 101 were enrolled in the survey study, and 65 were screened for or enrolled in either an open trial or a pilot randomized controlled trial. Data were collected between May 2004 and May 2009.

RESULTS

We found that the specificity of the PHQ-9 suicide screening item was 0.84 and sensitivity was 0.69 for the sample as a whole.

CONCLUSIONS

This study suggests that the routine use of the PHQ-9 may be useful in primary care practice in that it may identify individuals at risk for suicide who would not otherwise have been identified. However, denial of suicidality on the PHQ-9 should be probed further if there are other risk factors for suicide present.

E-health blood pressure control program

Both technological and human factors design requirements for integration of home blood pressure monitoring (HBPM) into a patient centered medical home (PCMH) model primary care practice are described. Patients with uncontrolled hypertension were given home blood pressure (BP) monitors, and after a three-month run-in period introduced to either a high-tech only (HBPM connectivity to personal health record and tailored Web portal access) or a high-tech/"high-touch" (high-tech solution plus patient navigator [PN]) solution. Features of the Web portal included: BP graphing function, traffic-light feedback system of BP goal attainment, economic incentives for self-monitoring, and dual patient-facing and care-team-facing dashboard functions. The e-health BP control system with PN support was well received by patients, providers, and the healthcare team. Current e-health technology and limited technological literacy of many patients suggest that a PN or some other personnel resource may be required for the adoption of patient-facing technology in primary care.

Time-invariant and time-varying predictors of depression symptoms in primary care patients

OBJECTIVE

The aims of this study were to examine correlates of depression symptoms, baseline predictors of change in depression symptoms, and time-varying predictors of depression symptoms in a primary care sample.

METHOD

In this study, we assessed depression symptoms and other variables at 3 time points over the course of 6 months in 103 primary care patients with elevated depression symptoms at baseline. Data collection occurred from May 2004 to September 2007.

RESULTS

Individuals with lower income levels and those who were not married had a poorer course of depression, as assessed by Center for Epidemiologic Studies Depression Scale score, over time. Several variables fluctuated in concert with depression symptoms within individuals over time. As depression symptoms improved, family functioning, problem-solving, pain, and general health perceptions also improved. A multivariate analysis showed that problem-solving and general health perceptions predicted significant (P < .001) unique variance in fluctuations in depression symptoms within individuals.

CONCLUSIONS

Care management programs for primary care depression may benefit from the inclusion of psychosocial interventions that directly target variables closely linked to depression, such as problem-solving and general health perceptions. In addition, special efforts must be made to help depressed individuals with low income and less social support.

A longitudinal investigation of marital adjustment as a risk factor for metabolic syndrome

OBJECTIVE

Metabolic syndrome (MetS) is a constellation of features--central obesity, dyslipidemia, elevated blood pressure, and dysglycemia--that are associated with increased risk for cardiovascular disease, diabetes, stroke, and mortality. This longitudinal study was conducted to evaluate whether marital adjustment, which has been shown to predict a variety of health outcomes, increases risk for incidence of MetS.

METHODS

A population-based English sample of couples (N = 216 couples) completed a self-report measure of marital adjustment at baseline and nurse visits that included collection of blood pressure, blood samples, and anthropometric measures at baseline and 4-year follow-up. Multilevel modeling was used to evaluate the association between both partners' report of baseline marital adjustment and incidence of MetS, controlling for other baseline risk factors (demographics, current and previous smoking status, alcohol use, activity level, depressive symptoms, number of MetS criteria).

RESULTS

Gender moderated the association between marital adjustment and incidence of MetS. Follow-up analyses indicated that husbands' report of marital adjustment at baseline was significantly associated with incident MetS for wives at follow-up, controlling for baseline risk factors. Marital adjustment was not significantly associated with incident MetS for men.

CONCLUSIONS

Findings suggest that MetS may be one mechanism by which poor marital adjustment increases risk for poor health outcomes in women. Improving marital adjustment may help prevent the incidence of MetS and improve health, particularly for women.

Measuring homework completion in behavioral activation

The aim of this study was to develop and validate an observer-based coding system for the characterization and completion of homework assignments during Behavioral Activation (BA). Existing measures of homework completion are generally unsophisticated, and there is no current measure of homework completion designed to capture the particularities of BA. The tested scale sought to capture the type of assignment, realm of functioning targeted, extent of completion, and assignment difficulty. Homework assignments were drawn from 12 (mean age = 48, 83% female) clients in two trials of a 10-session BA manual targeting treatment-resistant depression in primary care. The two coders demonstrated acceptable or better reliability on most codes, and unreliable codes were dropped from the proposed scale. In addition, correlations between homework completion and outcome were strong, providing some support for construct validity. Ultimately, this line of research aims to develop a user-friendly, reliable measure of BA homework completion that can be completed by a therapist during session.

Likelihood of suicidality at varying levels of depression severity: a re-analysis of NESARC data

Although it is clear that increasing depression severity is associated with more risk for suicidality, less is known about at what levels of depression severity the risk for different suicide symptoms increases. We used item response theory to estimate the likelihood of endorsing suicide symptoms across levels of depression severity in an epidemiological data set. Regardless of depression severity, suicide attempts were less frequently endorsed than ideation, which was less frequently endorsed than feeling like one wanted to die. All suicide symptoms were generally less likely to be endorsed than other depression symptoms. There was a low probability of suicidality at depression levels that likely would not merit a diagnosis of major depression.

DSM-IV depressive symptom expression among individuals with a history of hypomania: a comparison to those with or without a history of mania

In an effort to advance an understanding of the phenomenology of bipolar II depression, the current study used methods based in item response theory to evaluate differences in DSM-IV depression symptom endorsement in an epidemiological sample of individuals with a history of hypomania (i.e., bipolar II depression) in comparison to: a) individuals with a history of mania (i.e., bipolar I depression), and b) individuals without a history of hypomania or mania (i.e., unipolar depression). Clinical interview data were drawn from a subsample (n = 13,753) of individuals with bipolar II, bipolar I, or unipolar depression who had participated in the National Epidemiologic Survey on Alcohol and Related Conditions. A two-parameter item response model was used to estimate differential item functioning (DIF) between these groups. Differences in severity parameter estimates revealed that suicidal ideation/attempt was less likely to be endorsed across most levels of depression severity in bipolar II versus bipolar I disorder. There were no significant differences between groups on the remaining DSM-IV symptoms. Although preliminary, current study data are consistent with recent assertions that depression may be understood as a clinical phenomenon that is consistent across the major affective disorders. An exception to this conclusion may be in the area of suicidal ideation, which requires additional attention.

Marital distress and the metabolic syndrome: linking social functioning with physical health

Mechanisms by which poor relationship functioning contributes to poor health are not fully understood. We conducted a study to evaluate the association between marital distress and the metabolic syndrome (MetS), which refers to a clustering of characteristics that have individually been shown to be associated with elevated risk of cardiovascular disease and diabetes and which collectively have been shown to increase risk for cardiovascular disease, diabetes, stroke, and mortality. A population-based English sample of couples (N = 671 couples) in which both partners were between the ages of 52 and 79 years old completed a self-report measure of marital distress and a nurse visit that included collection of blood pressure, blood samples, and anthropometric measures. Results indicated that for women, after controlling for demographic variables, greater marital distress was significantly associated with increasing likelihood of meeting criteria for the MetS and with the individual MetS criteria of elevated blood pressure and elevated fasting glucose. The association between marital distress and the MetS remained significant for women when additionally controlling for depressive symptoms and health habits (smoking status, physical activity). Marital distress was not significantly associated with the MetS or any of the individual MetS criteria for men.

Open Trial of Vinyasa Yoga for Persistently Depressed Individuals: Evidence of Feasibility and Acceptability

The aim of this study was to assess the acceptability and feasibility of Vinyasa yoga as an adjunctive treatment for depressed patients who were not responding adequately to antidepressant medication. The authors also planned to ask participants for qualitative feedback on their experience of the class and to assess change over time in depression and in possible mediating variables. The authors recruited 11 participants in 1 month for an 8-week open trial of yoga classes. They found that 10 participants completed follow-up assessments, 9 of 10 were positive about their experience, and all provided feedback about what was and was not helpful about yoga, as well as barriers to class attendance. Over the 2-month period, participants exhibited significant decreases in depression symptoms and significant increases in an aspect of mindfulness and in behavior activation. This pilot study provided support for continuing to investigate Vinyasa yoga as an adjunct treatment for depression. The next step required is a rigorous randomized clinical trial.

Treatment of depression in a low-income primary care setting with colocated mental health care

In order to characterize depression treatment-as-usual in a large primary care practice in the United States with colocated mental health care, and to examine predictors of receiving any treatment and receiving adequate treatment, primary care patients were systematically approached in waiting rooms. Those with a minimum level of depression symptoms (n = 91) were asked to participate in a study in which they completed assessments of mental health service use, depression symptoms, and related problems. Results suggested that most patients with elevated depressive symptoms were receiving some type of mental health care, indicating they had been identified as depressed. However, only half were receiving "minimally adequate care." Minority patients were less likely to receive any care. Patients who were more depressed, demonstrated poorer problem-solving ability, and had poorer physical health were more likely to receive any treatment and to receive minimally adequate treatment for depression. These results suggest that, even in the context of colocated mental health care, there is still room for improving treatment of depressed patients.
