Differences in treatment attitudes between depressed African-American and Caucasian veterans in primary care

OBJECTIVES

Depressive disorders are common, and it is important to understand the factors that contribute to racial disparities in depression treatment. This primary care study of veterans with subsyndromal depression examined two hypotheses: that African Americans would be less likely than Caucasians to believe that medication is beneficial in depression treatment and would be more likely to believe that counseling or psychotherapy is beneficial.

METHODS

Primary care patients with subsyndromal depression were referred to the Philadelphia Department of Veterans Affairs Behavioral Health Laboratory and asked about past experiences and attitudes toward depression treatment.

RESULTS

Among 111 African-American and 95 Caucasian participants, logistic regression analyses determined that African Americans were less likely to view medication as beneficial (odds ratio=.44). No racial differences were found in participants' attitude toward counseling or psychotherapy.

CONCLUSIONS

The findings support the premise that clinicians treating patients with subsyndromal depressive syndromes should take into account racial differences in attitudes toward treatment.

Describing depression: congruence between patient experiences and clinical assessments

OBJECTIVES

Efforts to describe depression have relied on top-down methods in which theory and clinical experience define depression but may not reflect the individuals' experiences with depression. We assessed the degree of overlap between academic descriptions of depression and patient-reported symptoms as conceptualized in the Patient-Reported Outcomes Measurement Information System(®) (PROMIS(®)). By extension, this work assesses the degree of overlap between current clinical descriptions of depression and patient-reported symptoms.

DESIGN

In this content analysis study, four focus groups were conducted across two sites to elicit symptoms and the experience of depression from depressed and medically ill patients.

METHODS

Depressed and medically ill patients were asked to describe symptoms that characterize depression. Data were transcribed and then coded using an a priori list of 43 facets of depression derived from extant depression measures.

RESULTS

Participants described 93% of the symptoms from the a priori list, supporting the validity of current depression measures. Interpersonal difficulties were underscored as was anger. In general, results from the focus groups did not require the generation of new items for depression and supported the content validity of the PROMIS hierarchical framework and item pool created originally.

CONCLUSIONS

This work supports the validity of current depression assessment, but suggests further investigation of interpersonal functioning and anger may add to the depth and breadth of depression assessment.

Striking the (Im)Proper Balance between Scientific Advances and Clinical Utility: Commentary on the DSM-5 Proposal for Personality Disorders

We review briefly the contributions of Skodol, Pincus, and Widiger (this issue) describing and critiquing the proposed changes in the assessment of personality and personality disorders for the DSM-5. Despite the hard work of the DSM-5 Work Group to date, there are shortcomings and areas of controversy in the current proposal that demand further attention and change. We discuss the controversy in the broader context of the DSM over the past 30 years. In addressing specific problems, we focus on the limitations of the proposed system for assessing traits (even as we endorse the movement toward dimensional assessment of personality) and the difficulties posed by the current "hybrid" model that attempts to include both traits and types. In moving forward, we suggest greater emphasis on decision-making regarding the presence and severity of any personality disorder (understood on the basis of generalized failures in adaptation) and greater flexibility in identifying the variants of personality disorders in order to accommodate both traits and types more inclusively during this transition toward dimensional approaches to assessment.

Treating depression to remission in older adults: a controlled evaluation of combined escitalopram with interpersonal psychotherapy versus escitalopram with depression care management

OBJECTIVE

More than half of the older adults respond only partially to first-line antidepressant pharmacotherapy. Our objective was to test the hypothesis that a depression-specific psychotherapy, Interpersonal Psychotherapy (IPT), when used adjunctively with escitalopram, would lead to a higher rate of remission and faster resolution of symptoms in partial responders than escitalopram with depression care management (DCM).

METHOD

We conducted a 16-week randomized clinical trial of IPT and DCM in partial responders to escitalopram, enrolling 124 outpatients aged 60 and older. The primary outcome, remission, was defined as three consecutive weekly scores of 7 or less on the Hamilton rating scale for depression (17-item). We conducted Cox regression analyses of time to remission and logistic modeling for rates of remission. We tested group differences in Hamilton depression ratings over time via mixed-effects modeling.

RESULTS

Remission rates for escitalopram with IPT and with DCM were similar in intention-to-treat (IPT vs. DCM: 58 [95% CI: 46, 71] vs. 45% [33,58]; p = 0.14) and completer analyses (IPT vs. DCM: 58% [95% CI: 44,72] vs. 43% [30,57]; p = 0.20). Rapidity of symptom improvement did not differ in the two treatments.

CONCLUSION

No added advantage of IPT over DCM was shown. DCM is a clinically useful strategy to achieve full remission in about 50% of partial responders.

Adapting problem-solving therapy for depressed older adults in methadone maintenance treatment

Late-life depression is prevalent in older adults who are dependent on opiates. Depressive disorders among opiate abusers have detrimental effects on their well-being and ability to refrain from illegal drugs. There are numerous barriers to the provision of appropriate mental health care to older adults receiving methadone maintenance treatment. This article focuses on problem-solving therapy (PST) and presents evidence that PST may be a promising nonpharmacological treatment for older methadone clients with comorbid depressive disorders that can be applied within the staffing and resource limits of methadone maintenance treatment facilities. The advantages of PST relative to other behavioral therapies for this population are based on evidence that PST is less cognitively demanding for an older adult population with mood and substance use disorders. A properly modified PST for an older adult substance-dependent population with subsyndromal or diagnosed depression may be a viable option for methadone maintenance programs with limited resources.

Using clinician-rated five-factor model data to score the DSM-IV personality disorders

Proposals suggest that many or all of the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) personality disorders (PDs) may be omitted from the DSM (5th ed.; DSM-V) and replaced with a dimensional trait model of personality pathology (Krueger, Skodol, Livesley, Shrout, & Huang, 2007; Skodol, 2009). Several authors have expressed concerns that this may be difficult for clinicians and researchers who are more comfortable with the extant PD diagnoses. In this study, we tested whether clinician ratings of traits from the Five-factor model (FFM; Costa & McCrae, 1990) can be used to recreate DSM-IV PDs. Using a sample of 130 clinical outpatients, we tested the convergent and discriminant validity of the FFM PD counts in relation to consensus ratings of the DSM-IV PDs. We then examined whether the FFM and DSM-IV PD scores correlate in similar ways with self-reported personality traits from the Schedule for Nonadaptive and Adaptive Personality (Clark, 1993). Finally, we tested the clinical utility of the FFM PD counts in relation to functional impairment. Overall, the FFM PD counts, scored using clinician ratings of the FFM traits, appeared to function like the DSM-IV PDs, thus suggesting that the use of a dimensional trait model of personality in the DSM-V may still allow for an assessment of the DSM-IV PD constructs.

Racial preferences for participation in a depression prevention trial involving problem-solving therapy

OBJECTIVES

This study compared African Americans' and Caucasians' willingness to participate in an indicated intervention to prevent depression with problem-solving therapy. It also examined participants' problem-solving skills. Hypotheses stated that there would be no racial differences in consent rates and that social problem-solving coping skills would be lower among African Americans than Caucasians.

METHODS

Proportions of African Americans and Caucasians who consented were compared, as were Social Problem Solving Inventory scores between the groups.

RESULTS

Of 2,788 individuals approached, 82 (4%) of 1,970 Caucasians and 46 (6%) of 818 African Americans signed consent, and the difference was not significant (p=.09). Racial differences were observed in neither Social Problem Solving Inventory scores nor in the relationship between problem-solving skills and depressive symptoms.

CONCLUSIONS

African Americans with depression demonstrated a willingness to participate in an indicated trial of depression prevention. Furthermore, both groups would appear to benefit from the problem-solving process.

Examining the reliability and validity of clinician ratings on the Five-Factor Model Score Sheet

Despite substantial research use, measures of the five-factor model (FFM) are infrequently used in clinical settings due, in part, to issues related to administration time and a reluctance to use self-report instruments. The current study examines the reliability and validity of the Five-Factor Model Score Sheet (FFMSS), which is a 30-item clinician rating form designed to assess the five domains and 30 facets of one conceptualization of the FFM. Studied in a sample of 130 outpatients, clinical raters demonstrated reasonably good interrater reliability across personality profiles and the domains manifested good internal consistency with the exception of Neuroticism. The FFMSS ratings also evinced expected relations with self-reported personality traits (e.g., FFMSS Extraversion and Schedule for Nonadaptive and Adaptive Personality Positive Temperament) and consensus-rated personality disorder symptoms (e.g., FFMSS Agreeableness and Narcissistic Personality Disorder). Finally, on average, the FFMSS domains were able to account for approximately 50% of the variance in domains of functioning (e.g., occupational, parental) and were even able to account for variance after controlling for Axis I and Axis II pathology. Given these findings, it is believed that the FFMSS holds promise for clinical use.

The Mood Disorder Burden Index: a scale for assessing the burden of caregivers to adults with unipolar or bipolar disorder

We present a brief measure of caregiver burden, the Mood Disorder Burden Index (MDBI), for use with family members and close friends of adults with major depressive disorder (MDD) or bipolar disorder (BD). The MDBI assesses burden in three core domains (patients' mood symptoms, caregivers' worry about the future, and caregivers' interpersonal difficulties with the patient) and includes an optional module that assesses caregiver burden associated with patients' pharmacotherapy or psychotherapy. The MDBI was administered to caregivers of older individuals (i.e., 58 years and older) with MDD (n=123) or BD (n=38) who were receiving treatment through a research study. Analyses indicated evidence of convergent and discriminant validity of the new measure well as internal consistency within both caregiver groups. It will be important for future research to administer the MDBI to caregivers of middle-aged and older patients as well as those receiving treatment through inpatient settings or community outpatient clinics.

Anger, preoccupied attachment, and domain disorganization in borderline personality disorder

Emotional dysregulation and attachment insecurity have been reported in borderline personality disorder (BPD). Domain disorganization, evidenced in poor regulation of emotions and behaviors in relation to the demands of different social domains, may be a distinguishing feature of BPD. Understanding the interplay between these factors may be critical for identifying interacting processes in BPD and potential subtypes of BPD. Therefore, we examined the joint and interactive effects of anger, preoccupied attachment, and domain disorganization on BPD traits in a clinical sample of 128 psychiatric patients. The results suggest that these factors contribute to BPD both independently and in interaction, even when controlling for other personality disorder traits and Axis I symptoms. In regression analyses, the interaction between anger and domain disorganization predicted BPD traits. In recursive partitioning analyses, two possible paths to BPD were identified: high anger combined with high domain disorganization and low anger combined with preoccupied attachment. These results may suggest possible subtypes of BPD or possible mechanisms by which BPD traits are established and maintained.

Assessment procedures for narcissistic personality disorder: a comparison of the personality diagnostic questionnaire-4 and best-estimate clinical judgments

This study examined the degree of correspondence between two assessments for narcissistic personality disorder (NPD) in a mixed clinical and community sample--one using a self-report measure (Personality Diagnostic Questionnaire-4) and the other using clinical judgments derived from an assessment based on the longitudinal, expert, all data (LEAD) methodology. NPD scores demonstrated moderate convergence for the total scores but weak convergence for the individual criteria. The authors also examined the correlates created by each set of NPD scores using Cloninger's Temperament and Character Inventory (TCI). The NPD scores demonstrated areas of convergence (e.g., Cooperativeness, Self-directedness) and divergence (i.e., Harm Avoidance, Novelty Seeking) with these personality scores. These divergences may be due to the wording of certain items on the Personality Diagnostic Questionnaire-4 NPD scale, which may require rewriting if it is to provide an assessment that is more highly convergent with the Diagnostic and Statistical Manual of Mental Disorders NPD construct.

A controlled evaluation of monthly maintenance interpersonal psychotherapy in late-life depression with varying levels of cognitive function

OBJECTIVE

To evaluate the effect of maintenance Interpersonal Psychotherapy (IPT) on recurrence rates and time to recurrence of major depression in elderly patients with varying levels of cognitive function.

METHODS/DESIGN

Two-year maintenance study of monthly maintenance IPT vs supportive clinical management (CM) in remitted depressed elderly who were participants in a previously reported placebo-controlled study of maintenance paroxetine and IPT (Reynolds et al., 2006). We used Cox regression analysis to test interactions between cognitive status (Dementia Rating Scale score) and treatment (IPT, CM) with respect to recurrence of major depression.

RESULTS

We observed a significant interaction between cognitive status and treatment: lower cognitive performance was associated with longer time to recurrence in IPT than in CM (58 weeks vs 17 weeks) (HR = 1.41 [95% CI = 1.04, 1.91], p = 0.03). Subjects with average cognitive performance showed no effect of maintenance IPT vs CM on time to recurrence (38 vs 32 weeks, respectively).

CONCLUSION

Monthly maintenance IPT confers protection against recurrence of major depression in elders with lower cognitive functioning.

Impact of close family members on older adults' early response to depression treatment

This study of 130 depressed older adults and their spouses or adult children examined the impact of caregiver burden specific to patients' depressive symptoms on patients' response to antidepressant treatment. Primary care patients completed medical, psychiatric, and neuropsychological assessments prior to treatment, and interviews were conducted with their identified family member. As hypothesized, caregivers' depression-specific burden predicted greater depression severity for the patient at the 6th week of treatment after accounting for patients' pretreatment characteristics, caregivers' depressive symptoms, and caregivers' relationship satisfaction. Future research may identify family attitudes and behaviors that stem from burden and compromise older adults' ability to recover from depression.

The role of attachment styles and interpersonal problems in suicide-related behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide-related behaviors (i.e., self-harm, suicide attempts, and their co-occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide-related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.

Sexual orientation and adolescent substance use: a meta-analysis and methodological review

AIMS

Several decades of research have shown that lesbian, gay and bisexual (LGB) adults are at high risk for substance use and substance use disorders (SUDs). These problems may often start prior to young adulthood; however, relatively little is known about risk for substance use in LGB adolescents. The primary aims of this paper were to conduct a meta-analysis of the relationship between sexual orientation and adolescent substance use and a systematic review and critique of the methodological characteristics of this literature.

METHODS

Medical and social science journals were searched using Medline and PsychInfo. Studies were included if they tested the relationship between sexual orientation and adolescent substance use. Eighteen published studies were identified. Data analysis procedures followed expert guidelines, and used National Institutes of Health (NIH)-sponsored meta-analysis software.

RESULTS

LGB adolescents reported higher rates of substance use compared to heterosexual youth (overall odds ratio = 2.89, Cohen's d = 0.59). Effect sizes varied by gender, bisexuality status, sexual orientation definition and recruitment source. None of the studies tested mediation and only one tested moderation. One employed a matched comparison group design, one used a longitudinal design, and very few controlled for possible confounding variables.

CONCLUSIONS

The odds of substance use for LGB youth were, on average, 190% higher than for heterosexual youth and substantially higher within some subpopulations of LGB youth (340% higher for bisexual youth, 400% higher for females). Causal mechanisms, protective factors and alternative explanations for this effect, as well as long-term substance use outcomes in LGB youth, remain largely unknown.

Screening for personality disorders

A brief but valid self-report measure to screen for personality disorders (PDs) would be a valuable tool in making decisions about further assessment and in planning optimal treatments. In psychiatric and nonpsychiatric samples, we compared the validity of three screening measures: the PD scales from the Inventory of Interpersonal Problems, a self-report version of the Iowa Personality Disorder Screen, and the selfdirectedness scale of the Temperament and Character Inventory. Despite their different theoretical origins, the screeners were highly correlated in a range from .71 to .77. As a result, the use of multiple screeners was not a significant improvement over any individual screener, and no single screener stood out as clearly superior to the others. Each performed modestly in predicting the presence of any PD diagnosis in both the psychiatric and nonpsychiatric groups. Performance was best when predicting a more severe PD diagnosis in the psychiatric sample. The results also highlight the potential value of multiple assessments when relying on self-reports.

Impact of cluster C personality disorders on outcomes of acute and maintenance treatment in late-life depression

OBJECTIVE

Personality disorders (PDs) have been associated with poor treatment outcomes in acute treatments for late-life depression and with persistent functional impairment after recovery from an episode of depression.

METHODS

Using survival analysis and mixed-effects models, the authors examined the impact of Cluster C PDs on time-to-response and several aspects of functioning in acute and maintenance treatment of major depression in later life.

RESULTS

Cluster C PDs were associated with longer time-to-response during acute treatment and non-response in continuation or maintenance treatment. Although not statistically significant, there was evidence of a cumulative negative impact of Cluster C PDs and residual depressive symptoms on instrumental activities of daily living (IADLs) during maintenance treatment.

CONCLUSIONS

These findings suggest that screening for PD may be important for clinicians treating late-life depression and that the combination of Cluster C PDs and residual depressive symptoms may predict functional declines even after recovery from the index episode of depression.

Personality--life event congruence effects in late-life depression

BACKGROUND

This study examined whether specific interactions of personality and life events predicted increases in depressive symptoms over time in a late-life sample.

METHOD

Participants (n=55) who were in remission from a recent episode of major depression completed a depression symptom interview and a questionnaire assessing the personality constructs sociotropy and autonomy. Six months later, they completed the same personality questionnaire and a checklist of life events experienced during the past 6 months.

RESULTS

As predicted, increases in depressive symptoms were significantly predicted by the congruent interaction of sociotropy with negative interpersonal events and by the congruent interaction of autonomy with negative autonomy events, but not by either of the non-congruent interactions.

LIMITATIONS

A small sample prevented examinations of important depressive subtypes based on age of depression onset and vascular status.

CONCLUSIONS

These findings strongly support the personality-life event congruence model of depression in a late-life sample. Clinical implications include attending to stressful events that match an older adult's personality style, to help the older adult cope with those events that are more likely to increase his or her depression.

A model predicting suicidal ideation and hopelessness in depressed older adults: the impact of emotion inhibition and affect intensity

The purpose of this study was to begin a preliminary examination of constructs theorized to be related to suicidal behavior by testing a model of the influence of both temperament and emotion regulation on suicidal ideation and hopelessness in a sample of depressed older adults. The model was evaluated using structural equation modeling procedures in a sample of depressed, older adults. Findings supported a temporally predictive model in which negative affect intensity and reactivity lead to emotion inhibition, operationalized as ambivalence over emotional expression and thought suppression, which in turn lead to increased presence of suicidal predictors, operationalized as hopelessness and suicidal ideation. These results suggest that suicide prevention efforts in older adults may be improved by targeting emotion inhibition in treatment, especially among affectively intense and reactive older adults.

Five-factor model prototypes for personality disorders: the utility of self-reports and observer ratings

The current study examined the prototype-matching technique for using the five-factor model (FFM) of personality to assess personality disorders (PDs) and their correlates. The sample was composed of 69 psychiatric patients, most of whom suffered from affective or anxiety disorders. The participants were predominantly outpatients (78%), Caucasian (94%), and women (58%). NEO Personality Inventory (NEO-PI) data from these patients and informants were available for deriving PD prototype scores. The results supported four conclusions. First, the FFM prototype-matching method is useful for clinical samples. Second, agreement between self-reports and information from significant others (SOs) using this method is good compared to previous results. Third, this agreement varies systematically with the observability of the PD criteria. Fourth, the value of self- and other-reported personality information depends on the rating source of the outcome variables. Other-reported information provides incremental utility in predicting impairment and interpersonal distress rated by clinicians and significant others.

A preliminary investigation of self-reported personality disorders in late life: prevalence, predictors of depressive severity, and clinical correlates

Previous research suggests that personality disorders, particularly in clusters A and C, persist into late life, are particularly prevalent in late-life depressed samples, and negatively impact treatment of late-life depression. The present study examined the self-reported personality disorder traits of a sample of 65 depressed elders using the Wisconsin Personality Disorder Inventory IV (WISPI IV). As expected, clusters A and C were most prevalent and the presence of a personality disorder predicted the maintenance or re-emergence of depressive symptoms, as did hopelessness and ambivalence regarding emotional expression. No specific personality disorder traits were associated with clinical features of late-life depression (age of onset, number of previous episodes) while some personality disorder traits were associated with psychological correlates of depression (hopelessness, ambivalence regarding emotional expression, thought suppression). A theoretical explanation for the cluster prevalence based on self-verification is discussed along with a profile of elderly patients who may have poor depression treatment course if they exhibit personality disorder traits, particularly interpersonal rigidity or avoidance, chronic hopelessness, and emotional inhibition.

Dialectical behavior therapy for depressed older adults: a randomized pilot study

OBJECTIVE

Although there is evidence for the efficacy of antidepressants and for some individual and group psychotherapy interventions for depressed older adults, a significant number of these do not respond to treatment. Authors assessed the benefits of augmenting medication with group psychotherapy.

METHODS

They randomly assigned 34 (largely chronically) depressed individuals age 60 and older to receive 28 weeks of antidepressant medication plus clinical management, either alone (MED) or with the addition of dialectical behavior therapy skills-training and scheduled telephone coaching sessions (MED+DBT).

RESULTS

Only MED+DBT showed significant decreases on mean self-rated depression scores, and both treatment groups demonstrated significant and roughly equivalent decreases on interviewer-rated depression scores. However, on interviewer-rated depression, 71% of MED+DBT patients were in remission at post-treatment, in contrast to 47% of MED patients. At a 6-month follow-up, 75% of MED+DBT patients were in remission, compared with only 31% of MED patients, a significant difference. Only patients receiving MED+DBT showed significant improvements from pre- to post-treatment on dependency and adaptive coping that are proposed to create vulnerability to depression.

CONCLUSION

Results from this pilot study suggest that DBT skills training and telephone coaching may offer promise to effectively augment the effects of antidepressant medication in depressed older adults.

Sociotropy, autonomy, and personality disorder criteria in psychiatric patients

Sociotropy and autonomy (Beck, 1983) are sets of beliefs, concerns, and behavioral tendencies that are proposed to create vulnerability to depression and other psychopathology and to influence its manifestation and treatment response. Other theoretical frameworks (Blatt, 1974) have made similar suggestions. We investigated the differential relations of sociotropy and autonomy to dimensional scores for each DSM-III-R personality disorder (PD) in a sample of 188 psychiatric patients, controlling for the other set of characteristics and for the other PDs. Histrionic and dependent PD traits were related specifically to sociotropy. Paranoid, schizoid, schizotypal, and passive-aggressive PD traits were related specifically to autonomy. Borderline, narcissistic, avoidant, and self-defeating PD traits were related significantly and about equally to both sociotropy and autonomy. Obsessive-compulsive PD traits were not related consistently to either. Results were mostly as predicted and suggest that sociotropy and autonomy may be useful constructs for understanding and treating PDs.

Couple functioning in depression: the roles of sociotropy and autonomy

We evaluated the hypothesis that interpersonal relationships of depressed persons would vary as a function of the personality variables sociotropy and autonomy. Depressed psychiatric patients who reported being in a current intimate relationship for at least six months were administered measures of sociotropy, autonomy, and several aspects of relationship functioning. Results indicated that sociotropy was related significantly to patients' reporting their own behavior as demanding and their partners' behavior as withdrawing, whereas autonomy was related to patients' reporting their partners' behavior as demanding and their own behavior as withdrawing. Autonomy also was related to greater relationship dissatisfaction, and there was a trend for autonomy to be related to greater criticism of the partner. The results are consistent with a model in which sociotropy and autonomy increase vulnerability to depression, in part, through their effects on interpersonal relationships.
