RESUMEN

BACKGROUND: Collaborative care for depression is more effective in improving treatment outcomes than primary care physicians' (PCPs) usual care (UC). However, few trials of collaborative care have targeted anxiety. OBJECTIVE: To examine the impact and 12-month durability of a centralized, telephone-delivered, stepped collaborative care intervention (CC) for treating anxiety disorders across a network of primary care practices. DESIGN: Randomized controlled trial with blinded outcome assessments. PARTICIPANTS: A total of 329 patients aged 18-64 referred by their PCPs in response to an electronic medical record (EMR) prompt. They include 250 highly anxious patients randomized to either CC or to UC, and 79 moderately anxious patients who were triaged to a watchful waiting (WW) cohort and later randomized if their conditions clinically deteriorated. INTERVENTION: Twelve months of telephone-delivered CC involving non-mental health professionals who provided patients with basic psycho-education, assessed preferences for guideline-based pharmacotherapy, monitored treatment responses, and informed PCPs of their patients' care preferences and progress via the EMR. MAIN MEASURES: Mental health-related quality of life ([HRQoL]; SF-36 MCS); secondary outcomes: anxiety (Hamilton Anxiety Rating Scale [SIGH-A], Panic Disorder Severity Scale) and mood (PHQ-9). KEY RESULTS: At 12-month follow-up, highly anxious patients randomized to CC reported improved mental HRQoL (effect size [ES]: 0.38 [95 % CI: 0.13-0.63]; P = 0.003), anxiety (SIGH-A ES: 0.30 [0.05-0.55]; P = 0.02), and mood (ES: 0.45 [0.19-0.71] P = 0.001) versus UC. These improvements were sustained for 12 months among African-Americans (ES: 0.70-1.14) and men (ES: 0.43-0.93). Of the 79 WW patients, 29 % met severity criteria for randomization, and regardless of treatment assignment, WW patients reported fewer anxiety and mood symptoms and better mental HRQoL over the full 24-month follow-up period than highly anxious patients who were randomized at baseline. CONCLUSIONS: Telephone-delivered, centralized, stepped CC improves mental HRQoL, anxiety and mood symptoms. These improvements were durable and particularly evident among those most anxious at baseline, and among African-Americans and men.

RESUMEN

BACKGROUND: Yoga and physical exercise have been used as adjunctive intervention for cognitive dysfunction in schizophrenia (SZ), but controlled comparisons are lacking. Aims A single-blind randomised controlled trial was designed to evaluate whether yoga training or physical exercise training enhance cognitive functions in SZ, based on a prior pilot study. METHODS: Consenting, clinically stable, adult outpatients with SZ (n=286) completed baseline assessments and were randomised to treatment as usual (TAU), supervised yoga training with TAU (YT) or supervised physical exercise training with TAU (PE). Based on the pilot study, the primary outcome measure was speed index for the cognitive domain of 'attention' in the Penn computerised neurocognitive battery. Using mixed models and contrasts, cognitive functions at baseline, 21 days (end of training), 3 and 6 months post-training were evaluated with intention-to-treat paradigm. RESULTS: Speed index of attention domain in the YT group showed greater improvement than PE at 6 months follow-up (p<0.036, effect size 0.51). In the PE group, 'accuracy index of attention domain showed greater improvement than TAU alone at 6-month follow-up (p<0.025, effect size 0.61). For several other cognitive domains, significant improvements were observed with YT or PE compared with TAU alone (p<0.05, effect sizes 0.30-1.97). CONCLUSIONS: Both YT and PE improved attention and additional cognitive domains well past the training period, supporting our prior reported beneficial effect of YT on speed index of attention domain. As adjuncts, YT or PE can benefit individuals with SZ.

RESUMEN

OBJECTIVE: To identify actionable predictors of remission to antidepressant pharmacotherapy in depressed older adults and to use signal detection theory to develop decision trees to guide clinical decision making. METHOD: We treated 277 participants with current major depression using open-label venlafaxine XR (up to 300 mg/day) for 12 weeks, in an NIMH-sponsored randomized, placebo-controlled augmentation trial of adjunctive aripiprazole. Multiple logistic regression and signal detection approaches identified predictors of remission in both completer and intent-to-treat samples. RESULTS: Higher baseline depressive symptom severity (odds ratio [OR]: 0.86, 95% confidence interval [CI]: 0.80-0.93; p <0.001), smaller symptom improvement during the first two weeks of treatment (OR: 0.96, 95% CI: 0.94-0.97; p <0.001), male sex (OR: 0.41 95% CI: 0.18-0.93; p = 0.03), duration of current episode ≥2 years (OR: 0.26, 95% CI: 0.12-0.57; p <0.001) and adequate past depression treatment (ATHF ≥3) (OR: 0.34, 95% CI: 0.16-0.74; p = 0.006) predicted lower probability of remission in the completer sample. Subjects with Montgomery Asberg (MADRS) decreasing by greater than 27% in the first 2 weeks and with baseline MADRS scores of less than 27 (percentile rank = 51) had the best chance of remission (89%). Subjects with small symptom decrease in the first 2 weeks with adequate prior treatment and younger than 75 years old had the lowest chance of remission (16%). CONCLUSION: Our results suggest the clinical utility of measuring pre-treatment illness severity and change during the first 2 weeks of treatment in predicting remission of late-life major depression.

RESUMEN

BACKGROUND: Schizophrenia (SZ) is a chronic illness that is treated symptomatically. Cognitive dysfunction is a core feature of SZ that is relatively intractable to pharmacotherapy. Yoga can improve cognitive function among healthy individuals. A recent open trial indicated significant benefits of yoga training (YT) in conjunction with conventional pharmacotherapy among patients with SZ. AIMS: To describe the protocol for an ongoing randomised controlled trial designed to test whether the reported beneficial effects of YT on cognitive function among SZ patients can be replicated. Secondarily, the effects of YT on daily functioning living skills are evaluated. METHODS: Consenting patients with SZ receive routine clinical treatment and are randomised to adjunctive YT, adjunctive physical exercise (PE) or treatment as usual (proposed N = 234 total, N = 78 in each group). The trial involves YT or PE 5 days a week and lasts 3 weeks. Participants are evaluated thrice over 6 months. Cognitive functions measured by Trail Making Test, University of Pennsylvania Neurocognitive Computerised Battery were primary outcome measures while clinical severity and daily functioning measured by Independent Living Skills Survey were secondary outcome measures. RESULTS: A total of 309 participants have been randomised as of 31 August 2013, which exceeded beyond 294 proposed after attrition. Once participants begin YT or PE they generally complete the protocol. No injuries have been reported. CONCLUSIONS: Short term YT is feasible and acceptable to Indian SZ patients. If beneficial effects of YT are detected, it will provide a novel adjunctive cognitive remediation strategy for SZ patients.

RESUMEN

BACKGROUND: Primary care patients with Panic Disorder (PD) and Generalized Anxiety Disorder (GAD) experience poorer than expected clinical outcomes, despite the availability of efficacious pharmacologic and non-pharmacologic treatments. A barrier to recovery from PD/GAD may be the co-occurrence of pain. OBJECTIVE: To evaluate whether pain intensity interfered with treatment response for PD and/or GAD in primary care patients who had received collaborative care for anxiety disorders. DESIGN: A secondary data analysis of a randomized, controlled effectiveness trial comparing a telephone-delivered collaborative care intervention for primary care patients with severe PD and/or GAD to their doctor's "usual" care. PARTICIPANTS: Patients had to have a diagnosis of PD and/or GAD and a severe level of anxiety symptoms. The 124 patients randomized at baseline to the collaborative care intervention were analyzed. Participants were divided into two pain intensity groups based on their response to the SF-36 Bodily Pain scale (none or mild pain vs. at least moderate pain). MAIN MEASURES: Pain was assessed using the Bodily Pain scale of the SF-36. Anxiety symptoms were measured with the Hamilton Anxiety Rating Scale (HRS-A), Panic Disorder Severity Scale (PDSS) and Generalized Anxiety Disorder Severity Scale (GADSS). Measures were collected over 12 months. KEY RESULTS: At baseline, patients with at least moderate pain were significantly more likely to endorse more anxiety symptoms on the HRS-A than patients with no pain or mild pain (P < .001). Among patients with severe anxiety symptoms, 65 % (80/124) endorsed experiencing at least moderate pain in the previous month. A significantly lesser number of patients achieved a 50 % improvement at 12 months on the HRS-A and GADSS if they had at least moderate pain as compared to patients with little or no pain (P = 0.01 and P = 0.04, respectively). CONCLUSIONS: Coexisting pain was common in a sample of primary care patients with severe PD/GAD, and appeared to negatively affect response to anxiety treatment.

RESUMEN

OBJECTIVES: The aim of this study is to compare the Empirical Behavioral Rating Scale (E-BEHAVE-AD), Neurobehavioral Rating Scale (NBRS), and Neuropsychiatric Interview (NPI) in detecting behavioral disturbance and psychotic symptoms in dementia and characterizing changes in response to treatment. DESIGN: Eighty-seven subjects in the randomized controlled trial "Continuation Pharmacotherapy for Agitation of Dementia" were included in this analysis. We compared the detection in, and changes of, both agitation and psychosis, using these three instruments. A receiver operating characteristic analysis was performed to compare the performance of the three instruments in detecting global improvement. RESULTS: The instruments were equally likely to detect agitation. The NBRS was most likely to detect psychosis. Although the NPI best detected improvement in agitation, the instruments were equal for detecting improvement in psychosis. In the receiver operating characteristic analysis for overall clinical improvement in response to treatment, there were no differences in the areas under the correlated curves for the three instruments, but they demonstrated different sensitivity and specificity at different cutoff points for target symptom reduction. The E-BEHAVE-AD performed best at a cut point of 30% target symptom reduction and the NBRS and NPI both performed best at 50%. CONCLUSION: The E-BEHAVE-AD, NBRS, and NPI were more similar than different in characterizing symptoms but differed in detecting response to treatment. Differences in sensitivity and specificity may lead clinicians to prefer a specific instrument, depending on their goal and the expected magnitude of response to any specific intervention.

RESUMEN

Randomized trials for selective and indicated prevention of depression in both mixed-aged and older adult samples, conducted in high-income countries (HICs), show that rates of incident depression can be reduced by 20-25% over 1-2 years through the use of psychoeducational and psychological interventions designed to increase protective factors. Recurrence of major depression can also be substantially reduced through both psychological and psychopharmacological strategies. Additional research is needed, however, to address the specific issues of depression prevention in older adults in low- and middle-income countries (LMICs). The growing number of older adults globally, as well as workforce issues and the expense of interventions, makes it important to develop rational, targeted, and cost-effective risk-reduction strategies. In our opinion, one strategy to address these issues entails the use of lay health counselors (LHCs), a form of task shifting already shown to be effective in the treatment of common mental disorders in LMICs. We suggest in this review that the time is right for research into the translation of depression-prevention strategies for use in LMICs.

RESUMEN

BACKGROUND: Given the association of depression with poorer cardiac outcomes, an American Heart Association Science Advisory has advocated routine screening of cardiac patients for depression using the 2-item Patient Health Questionnaire (PHQ-2) "at a minimum." However, the prognostic value of the PHQ-2 among HF patients is unknown. METHODS AND RESULTS: We screened hospitalized HF patients (ejection fraction [EF] <40%) that staff suspected may be depressed with the PHQ-2, and then determined vital status at up to 12-months follow-up. At baseline, PHQ-2 depression screen-positive patients (PHQ-2+; n = 371), compared with PHQ-2 screen-negative patients (PHQ-2-; n = 100), were younger (65 vs 70 years) and more likely to report New York Heart Association (NYHA) functional class III/IV than class II symptoms (67% vs. 39%) and lower levels of physical and mental health-related quality of life (all P ≤ .002); they were similar in other characteristics (65% male, 26% mean EF). At 12 months, 20% of PHQ-2+ versus 8% of PHQ-2- patients had died (P = .007) and PHQ-2 status remained associated with both all-cause (hazard ratio [HR] 3.1, 95% confidence interval [CI] 1.4-6.7; P = .003) and cardiovascular (HR 2.7, 95% CI 1.1-6.6; P = .03) mortality even after adjustment for age, gender, EF, NYHA functional class, and a variety of other covariates. CONCLUSIONS: Among hospitalized HF patients, a positive PHQ-2 depression screen is associated with an elevated 12-month mortality risk.

RESUMEN

OBJECTIVE: Optimism has been associated with a lower risk of rehospitalization after coronary artery bypass graft (CABG) surgery, but little is known about how optimism affects treatment of depression in post-CABG patients. METHODS: Using data from a collaborative care intervention trial for post-CABG depression, we conducted exploratory post hoc analyses of 284 depressed post-CABG patients (2-week posthospitalization score in the 9-item Patient Health Questionnaire ≥ 10) and 146 controls without depression who completed the Life Orientation Test - Revised (full scale and subscale) to assess dispositional optimism. We classified patients as optimists and pessimists based on the sample-specific Life Orientation Test - Revised distributions in each cohort (full sample, depressed, nondepressed). For 8 months, we assessed health-related quality of life (using the 36-item Short-Form Health Survey) and mood symptoms (using the Hamilton Rating Scale for Depression [HRS-D]) and adjudicated all-cause rehospitalization. We defined treatment response as a 50% or higher decline in HRS-D score from baseline. RESULTS: Compared with pessimists, optimists had lower baseline mean HRS-D scores (8 versus 15, p = .001). Among depressed patients, optimists were more likely to respond to treatment at 8 months (58% versus 27%, odds ratio = 3.02, 95% confidence interval = 1.28-7.13, p = .01), a finding that was not sustained in the intervention group. The optimism subscale, but not the pessimism subscale, predicted treatment response. By 8 months, optimists were less likely to be rehospitalized (odds ratio = 0.54, 95% confidence interval = 0.32-0.93, p = .03). CONCLUSIONS: Among depressed post-CABG patients, optimists responded to depression treatment at higher rates. Independent of depression, optimists were less likely to be rehospitalized by 8 months after CABG. Further research should explore the impact of optimism on these and other important long-term post-CABG outcomes.

RESUMEN

OBJECTIVE: To describe the methodology of the first NIH-funded clinical trial for seniors with comorbid depression and chronic low back pain. METHODS: Randomized controlled effectiveness trial using stepped care methodology. Participants are ≥60 years old. Phase 1 (6 weeks) is open treatment with venlafaxine xr 150 mg/day and supportive management (SM). Response is 2 weeks of PHQ-9 ≤5 and at least 30% improvement in the average numeric rating scale for pain. Nonresponders progress to phase 2 (14 weeks) in which they are randomized to high-dose venlafaxine xr (up to 300 mg/day) with problem solving therapy for depression and pain (PST-DP) or high-dose venlafaxine xr and continued SM. Primary outcomes are the univariate pain and depression response and both observed and self-reported disability. Survival analytic techniques will be used, and the clinical effect size will be estimated with the number needed to treat. We hypothesize that self-efficacy for pain management will mediate response for subjects randomized to venlafaxine xr and PST-DP. RESULTS: Not applicable. CONCLUSIONS: The results of this trial will inform the care of these complex patients and further understanding of comorbid pain and depression in late life.

RESUMEN

Tree-structured survival methods empirically identify a series of covariate-based binary split points, resulting in an algorithm that can be used to classify new patients into risk groups and subsequently guide clinical treatment decisions. Traditionally, only fixed-time (e.g. baseline) values are used in tree-structured models. However, this manuscript considers the scenario where temporal features of a repeated measures polynomial model, such as the slope and/or curvature, are useful for distinguishing risk groups to predict future outcomes. Both fixed- and random-effects methods for estimating individual temporal features are discussed, and methods for including these features in a tree model and classifying new cases are proposed. A simulation study is performed to empirically compare the predictive accuracies of the proposed methods in a wide variety of model settings. For illustration, a tree-structured survival model incorporating the linear rate of change of depressive symptomatology during the first four weeks of treatment for late-life depression is used to identify subgroups of older adults who may benefit from an early change in treatment strategy.

RESUMEN

BACKGROUND: Yoga therapy (YT) improves cognitive function in healthy individuals, but its impact on cognitive function among persons with schizophrenia (SZ) has not been investigated. AIMS: Evaluate adjunctive YT for cognitive domains impaired in SZ. METHODS: Patients with SZ received YT or treatment as usual (TAU; n = 65, n = 23, respectively). Accuracy and speed for seven cognitive domains were assessed using a computerized neurocognitive battery (CNB), thus minimizing observer bias. Separately, YT was evaluated among patients with Bipolar I disorder (n = 40), Major Depressive Disorder (n = 37), and cardiology outpatients (n = 68). All patients also received routine pharmacotherapy. Patients were not randomized to YT or TAU. RESULTS: Compared with the SZ/TAU group, the SZ/YT group showed significantly greater improvement with regard to measures of attention following corrections for multiple comparisons; the changes were more prominent among the men. In the other diagnostic groups, differing patterns of improvements were noted with small to medium effect sizes. CONCLUSIONS: Our initial analyses suggest nominally significant improvement in cognitive function in schizophrenia with adjunctive therapies such as YT. The magnitude of the change varies by cognitive domain and may also vary by diagnostic group.

RESUMEN

OBJECTIVE: To explore relationships between wake- and sleep-related health behaviors and circulating concentrations of inflammatory markers (interleukin [IL]-6 and tumor necrosis factor [TNF]-α) in a cohort of community dwelling older adults. Low-grade chronic inflammation is an important risk factor for age-related morbidity. Health behaviors, including average aggregate measures of sleep, have been linked to increased inflammation in older adults. Variability in sleep timing may also be associated with increased inflammation. METHOD: Participants were community dwelling older adults ≥ 60 years (n = 222: 39 bereaved, 55 caregivers, 52 with insomnia, and 76 good sleepers). Mean values and intraindividual variability in sleep, as well as caffeine and alcohol use, exercise, and daytime napping, were assessed by sleep diaries. Blood samples were obtained in the morning. RESULTS: Several interactions were noted between sleep behaviors, inflammatory markers, and participant group. Greater variability in wake time and time in bed was associated with higher IL-6 among good sleepers relative to caregivers and older adults with insomnia. Good sleepers who consumed moderate amounts of alcohol had the lowest concentrations of IL-6 compared with the other three groups who consumed alcohol. Insomnia subjects, but not good sleepers, showed increased concentrations of IL-6 associated with caffeine use. Caregivers showed increased concentrations of TNF-α with alcohol use relative to good sleepers. Greater variability in bedtime, later wake times, and longer time in bed was associated with higher TNF-α regardless of group. CONCLUSIONS: Moderation and regularity in the practice of certain health behaviors, including sleep practices, were associated with lower plasma levels of inflammatory markers in older adults. Life circumstances and specific sleep disorders may modify these associations.

RESUMEN

OBJECTIVE: To determine the nature of telephone-delivered collaborative care intervention provided to patients younger than and older than 60 years experiencing clinically significant depressive symptoms after coronary artery bypass graft (CABG) surgery and whether patient age is related to response and remission rates and delivery of care at 8-month follow-up. DESIGN: : Exploratory post-hoc analysis of data collected in a randomized controlled trial (RCT). SETTING: Seven Pittsburgh-area general hospitals. PARTICIPANTS: Fifty-eight depressed post-CABG patients younger than 60 and 92 comparable patients age 60 years and older randomized to the RCT's intervention arm. MEASUREMENTS: : Components of collaborative care provided to patients over the 8-month study period and Hamilton Rating Scale for Depression scores at 8-month follow-up to determine response and remission status. RESULTS: There were no differences in the cumulative 8-month rates at which the components of collaborative care were delivered to the two age groups. Similar response and remission rates were also achieved by these groups. CONCLUSION: Older and younger patients experiencing clinical depression after CABG surgery can be treated with comparable components of collaborative care, and both age groups will achieve clinical outcomes that do not differ significantly from each other.

RESUMEN

OBJECTIVE: To describe the relationship between pain and depression on recovery after coronary artery bypass grafting (CABG). METHODS: A secondary data analysis on 453 depressed and nondepressed post-CABG patients enrolled in a randomized, controlled, effectiveness trial of telephone-delivered collaborative care for depression. Outcome measures were collected from March 2004 to September 2007 and included pain, physical function, and mood symptoms. RESULTS: Depressed patients (baseline Patient Health Questionnaire-9 score ≥10) versus those without depression reported significantly worse pain scores on the 36-Item Short Form Health Survey Bodily Pain Scale at baseline and up to 12 months post-CABG, p < .05. Among patients with depression, those who received collaborative care reported significantly better pain scores at each time point between 2 and 12 months post-CABG versus depressed patients randomized to the usual care control group, p < .05. Regardless of intervention status, depressed participants with at least moderate pain at baseline reported significantly lower functional status (measured by the Duke Activity Status Index) at 8 and 12 months versus depressed patients with none or mild pain, p < .05. Depressed patients with at least moderate pain at baseline were also significantly less likely to show improvement of depressive symptoms throughout the course of follow-up versus depressed patients with little or no pain, p < .05. These findings controlled for age, gender, education, race, comorbid conditions, and baseline pain diagnosis. CONCLUSIONS: Depression and pain seem to influence functional recovery post-CABG. The relationship between these two conditions and 12-month outcomes should be considered by clinicians when planning treatment.

RESUMEN

OBJECTIVES: To determine in healthy people aged > or = 75 years 1) if restricting time in bed and education in health sleep practices are superior to an attention-only control condition (i.e., education in healthy dietary practices) for maintaining or enhancing sleep continuity and depth over 2.5 years; and 2) if maintenance or enhancement of sleep continuity and depth promotes the maintenance or enhancement of health-related quality of life. METHODS: Single-blind, randomized, clinical trial in a university-based sleep center, enrolling 64 adults (n = 30 women, 34 men; mean age = 79 years) without sleep/wake complaints (e.g., insomnia or daytime sleepiness), followed by randomized assignment to either: 1) restriction of time in bed by delaying bedtime 30 minutes nightly for 18 months, together with education in healthy sleep practices (SLEEP); or 2) attention-only control condition with education in health dietary practices (NUTRITION). RESULTS: SLEEP did not enhance sleep continuity or depth; however, compared with NUTRITION, SLEEP was associated with decreased time spent asleep (about 30 minutes nightly over 18 months). Contrary to hypothesis, participants in SLEEP reported a decrement in physical health-related quality of life and an increase in medical burden (cardiovascular illness), relative to NUTRITION. Neither markers of inflammation, body mass index, or exercise explained treatment-related changes in medical burden. CONCLUSIONS: Although we cannot exclude a positive effect of education in healthy nutrition, for healthy elderly >75 years of age without sleep complaints, reducing sleep time may be detrimental, whereas allowing more time to sleep (about 7.5 hours nightly) is associated with better maintenance of physical health-related quality of life and stability of medical illness burden over 30 months.

RESUMEN

Missing covariate data present a challenge to tree-structured methodology due to the fact that a single tree model, as opposed to an estimated parameter value, may be desired for use in a clinical setting. To address this problem, we suggest a multiple imputation algorithm that adds draws of stochastic error to a tree-based single imputation method presented by Conversano and Siciliano (Technical Report, University of Naples, 2003). Unlike previously proposed techniques for accommodating missing covariate data in tree-structured analyses, our methodology allows the modeling of complex and nonlinear covariate structures while still resulting in a single tree model. We perform a simulation study to evaluate our stochastic multiple imputation algorithm when covariate data are missing at random and compare it to other currently used methods. Our algorithm is advantageous for identifying the true underlying covariate structure when complex data and larger percentages of missing covariate observations are present. It is competitive with other current methods with respect to prediction accuracy. To illustrate our algorithm, we create a tree-structured survival model for predicting time to treatment response in older, depressed adults.

RESUMEN

Sensitivity to psychotropic medications presents a therapeutic challenge when treating neuropsychiatric symptoms in patients with dementia with Lewy bodies (DLB). We compared under randomized, double-blinded conditions the tolerability and efficacy of citalopram and risperidone in the treatment of behavioral and psychotic symptoms in patients with DLB and Alzheimer disease (AD). Thirty-one participants with DLB and 66 with AD hospitalized for behavioral disturbance were treated under randomized, double-blind conditions with citalopram or risperidone for up to 12 weeks. Neuropsychiatric symptoms were assessed with the nursing home version of the Neuropsychiatric Inventory (NPI) and the Clinical Global Impression of Change (CGIC). Side effects were measured using the UKU Side Effect Rating Scale. A significantly higher proportion of participants with DLB (68%) than with AD (50%) discontinued the study prematurely. Discontinuation rates were comparable in DLB participants treated with citalopram (71%) or risperidone (65%). However, participants with DLB randomized to risperidone experienced a higher overall burden of side effects. Scores on the NPI and the CGIC worsened in DLB participants and improved in those with AD. Most patients with behavioral disturbances or psychosis associated with DLB tolerate citalopram or risperidone poorly and do not seem to benefit from either medication.

RESUMEN

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.

RESUMEN

This article describes patterns of concordance/discordance between self-reported abilities ("can do") and habits ("does do") and observed task performance of daily living tasks in three groups of older adults: late life depression with mild cognitive impairment (n=53), late life depression without mild cognitive impairment (n=64), and non-depressed, cognitively normal controls (n=31). Self-reported data were gathered by interview in participants' homes, followed by observation of task performance. Significant differences in the patterns of response were found between controls and respondents with both late life depression and mild cognitive impairment for the cognitive instrumental activities, and between the two depressed groups and controls for the physical instrumental activities. For both sets of activities, controls exhibited the greatest overestimation of task performance. No differences were found among the groups for the less complex functional mobility and personal care tasks. However, for the more complex instrumental activities, concordance was close to, or less than, chance. The findings led us to conclude that when performance testing is not feasible, self-reports of functional status that focus on habits may be more accurate than those that focus on abilities.
