Dissatisfaction with performance of valued activities predicts depression in age-related macular degeneration.

OBJECTIVE: To determine whether dissatisfaction with performance of valued activities predicts depression in patients with age-related macular degeneration (AMD). PATIENTS: Two hundred and six patients with newly diagnosed neovascular AMD in one eye and pre-existing AMD in the fellow eye who were participating in a clinical trial of a psychosocial intervention to prevent depression. MEASURES: Structured clinical evaluations of vision function, depression, visual acuity, contrast sensitivity and medical morbidity. Subjects were classified as dissatisfied if they indicated that they were dissatisfied with their performance of a valued activity. RESULTS: Subjects who were dissatisfied with performance of valued activities (n = 71) had similar demographic characteristics to satisfied subjects (n = 135) but had worse visual acuity (p < 0.054), greater medical comorbidity (p < 0.006), and lower vision function (p < 0.001). Dissatisfied subjects were almost 2.5 times more likely (OR = 2.41; [95% CI 1.02, 5.65]; p = 0.044) to become depressed within 2 months than satisfied subjects independent of baseline visual acuity, vision function, and medical comorbidity. CONCLUSION: Dissatisfaction with performance of valued activities in older persons with AMD predicts depression over a 2-month period. Assessing the ability to pursue valued activities may identify patients at risk for depression and prompt clinicians to initiate rehabilitative interventions and careful surveillance for depression.

Distress, psychiatric syndromes, and impairment of function in women with newly diagnosed breast cancer.

BACKGROUND: Emotional distress and psychiatric syndromes are prevalent in the breast cancer population at large. However, to date there is a paucity of literature specifically concerning presurgical breast cancer patients. METHODS: The authors assessed 236 newly diagnosed patients at the time of their presurgical consultation at the Comprehensive Breast Cancer Program of Dartmouth-Hitchcock Medical Center in Lebanon, NH. RESULTS: Of patients in this study, 41% rated their distress in the clinically significant range on the Distress Thermometer (ie, >5, 0-10 scale). Nearly one-half (47%) of patients met established thresholds for positivity on 1 or more screens for distress or psychiatric disorders. Prevalence rates were 11% for major depression (60% of these patients were moderately severe to severely depressed) and were 10% for posttraumatic stress disorder (PTSD). Emotional symptoms markedly interfered with daily function in both groups. Of depressed patients, 56% were already taking a psychotropic medication, yet they still met screening criteria for major depression. CONCLUSIONS: Emotional distress and psychiatric syndromes (major depression and PTSD) were prevalent in this population. Markedly impaired function was evident for both depressed and PTSD patients. Future research should refine current screening procedures and develop interventions to better address emotional distress and psychiatric disorders in newly diagnosed breast cancer patients.

Minimal depression and vision function in age-related macular degeneration.

OBJECTIVE: To evaluate the impact of minimal depression on subjective and objective vision function measures in age-related macular degeneration (AMD). DESIGN: Prospective cross-sectional study. PARTICIPANTS: Two hundred six outpatients with newly diagnosed neovascular AMD in one eye and preexisting AMD in the fellow eye. METHODS: Structured clinical evaluations of visual acuity (VA), contrast sensitivity, vision function, and depression. MAIN OUTCOME MEASURES: The 17-item National Eye Institute Visual Function Questionnaire (NEI VFQ 17), Melbourne Low-Vision Index (MLVI), Chronic Disease Score, and Hamilton Depression Rating Scale. RESULTS: Minimally depressed subjects had significantly worse vision function on both the NEI VFQ 17 and performance-based tasks of the MLVI than nondepressed subjects, independent of severity of VA, contrast sensitivity, and medical status. CONCLUSIONS: Minimally depressed patients with AMD, who would not be considered depressed according to current diagnostic standards, suffer decrements in vision function that cannot be accounted for by the severity of their eye disease or general medical problems. These data emphasize the need to assess depressive symptoms in research studies that use vision function outcome measures and in clinical practice to identify excess vision-related disability in patients with AMD.

Impact of comorbid panic and posttraumatic stress disorder on outcomes of collaborative care for late-life depression in primary care.

OBJECTIVE: Comorbid anxiety disorders may result in worse depression treatment outcomes. The authors evaluated the effect of comorbid panic disorder and posttraumatic stress disorder (PTSD) on response to a collaborative-care intervention for late-life depression in primary care. METHODS: A total of 1,801 older adults with depression were randomized to a collaborative-care depression treatment model versus usual care and assessed at baseline, 3, 6, and 12 months, comparing differences among participants with comorbid panic disorder (N=262) and PTSD (N=191) and those without such comorbid anxiety disorders. RESULTS: At baseline, patients with comorbid anxiety reported higher levels of psychiatric and medical illness, greater functional impairment, and lower quality of life. Participants without comorbid anxiety who received collaborative care had early and lasting improvements in depression compared with those in usual care. Participants with comorbid panic disorder showed similar outcomes, whereas those with comorbid PTSD showed a more delayed response, requiring 12 months of intervention to show a significant effect. At 12 months, however, outcomes were comparable. Interactions of intervention status by comorbid PTSD or panic disorder were not statistically significant, suggesting that the collaborative-care model performed significantly better than usual care in depressed older adults both with and without comorbid anxiety. CONCLUSIONS: Collaborative care is more effective than usual care for depressed older adults with and without comorbid panic disorder and PTSD, although a sustained treatment response was slower to emerge for participants with PTSD. Intensive and prolonged follow-up may be needed for depressed older adults with comorbid PTSD.

An interactive media program for managing psychosocial problems on long-duration spaceflights.

Space crews must be self-reliant to complete long-duration missions successfully. This project involves the development and evaluation of a network of self-guided interactive multimedia programs to train and assist long-duration flyers in the prevention, assessment, and management of psychosocial problems that can arise on extended missions. The system is currently under development and is intended for use both during training and on orbit. A virtual space station 3-dimensional graphic was created to serve as a portal to multimedia-based training, assessment, and intervention resources. Additionally, original content on interpersonal conflict and depression is being developed for the system. Input on the best practices for managing conflict and depression on extended missions was obtained from 13 veteran long-duration flyers, as well as from clinical experts. Formative evaluation of a prototype of the system will be conducted with 10 members of the astronaut corps. Subsequently, the content on conflict and depression will be completed, and the depression self-treatment portion will be evaluated in a randomized controlled trial. Although this study involves developing countermeasures to assist long-duration flyers, it also provides a model that could be applied in many Earthbound settings, both in operational environments and in everyday life.

Training residents in problem-solving treatment of depression: a pilot feasibility and impact study.

BACKGROUND AND OBJECTIVES: Primary care patients with depression may prefer or require a non-pharmacological treatment such as counseling. We investigated the feasibility of teaching family medicine residents an evidence-based brief counseling intervention for depression (Problem-solving Treatment of Depression for Primary Care [PST-PC]). METHODS: Eleven residents over 3 consecutive years were provided a brief training program in PST-PC. Residents were evaluated for skill acquisition, changes in self efficacy, intentions to improve their care for depression, and post-residency integration of PST-PC into their daily practice. RESULTS: Trainees met established criteria for competency to administer PST-PC. They improved to moderate-to-high levels of self efficacy for treating depression, including for their counseling skills, and in their intentions to improve their depression management. At up to 3 years post residency, 90% indicated they were using PST-PC, often in a modified form, and also for illnesses other than depression. They indicated they would recommend the training to new residents. CONCLUSIONS: The PST-PC training program evaluated in this study is feasible in residency training and appears to influence practice post residency. These findings warrant continued investigation of this training program with a larger sample of residents and evaluation of outcomes with depressed patients treated with PST-PC in real-world practice settings.

Collaborative care management of late-life depression in the primary care setting: a randomized controlled trial.

CONTEXT: Few depressed older adults receive effective treatment in primary care settings. OBJECTIVE: To determine the effectiveness of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) collaborative care management program for late-life depression. DESIGN: Randomized controlled trial with recruitment from July 1999 to August 2001. SETTING: Eighteen primary care clinics from 8 health care organizations in 5 states. PARTICIPANTS: A total of 1801 patients aged 60 years or older with major depression (17%), dysthymic disorder (30%), or both (53%). INTERVENTION: Patients were randomly assigned to the IMPACT intervention (n = 906) or to usual care (n = 895). Intervention patients had access for up to 12 months to a depression care manager who was supervised by a psychiatrist and a primary care expert and who offered education, care management, and support of antidepressant management by the patient's primary care physician or a brief psychotherapy for depression, Problem Solving Treatment in Primary Care. MAIN OUTCOME MEASURES: Assessments at baseline and at 3, 6, and 12 months for depression, depression treatments, satisfaction with care, functional impairment, and quality of life. RESULTS: At 12 months, 45% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 19% of usual care participants (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.71-4.38; P<.001). Intervention patients also experienced greater rates of depression treatment (OR, 2.98; 95% CI, 2.34-3.79; P<.001), more satisfaction with depression care (OR, 3.38; 95% CI, 2.66-4.30; P<.001), lower depression severity (range, 0-4; between-group difference, -0.4; 95% CI, -0.46 to -0.33; P<.001), less functional impairment (range, 0-10; between-group difference, -0.91; 95% CI, -1.19 to -0.64; P<.001), and greater quality of life (range, 0-10; between-group difference, 0.56; 95% CI, 0.32-0.79; P<.001) than participants assigned to the usual care group. CONCLUSION: The IMPACT collaborative care model appears to be feasible and significantly more effective than usual care for depression in a wide range of primary care practices.

Health functioning impairments associated with posttraumatic stress disorder, anxiety disorders, and depression.

Although anxiety disorders have been associated with impairments in self-reported health functioning, the relative effect of various anxiety disorders has not been studied. We compared health functioning of patients with a principal diagnosis of posttraumatic stress disorder (PTSD), panic disorder (PD), generalized anxiety disorder (GAD), and major depressive disorder (MDD). Patients with PTSD and MDD were equally impaired on overall mental health functioning, and both were significantly worse than patients with PD and GAD. PTSD was associated with significantly worse physical health functioning relative to PD, GAD, and MDD. Hierarchical regression showed that the association of PTSD with physical health functioning was unique and was not caused by the effects of age, depression, or comorbid anxiety disorders. Both PTSD and comorbid anxiety accounted for unique variance in mental functioning. These results highlight the association of PTSD with impaired physical and mental functioning and suggest that effective treatment of PTSD may affect overall health.

Posttraumatic stress disorder in primary care: prevalence and relationships with physical symptoms and medical utilization.

OBJECTIVE: This study estimates the prevalence of posttraumatic stress disorder (PTSD) and describes the relationships among PTSD status and health indices in a civilian primary care patient sample. METHODS: Participants (N = 232) completed a paper-and-pencil survey of life events, PTSD symptoms, physical symptoms and health functioning. Utilization was assessed from medical records. RESULTS: Nine percent of the participants met the criteria for full PTSD (based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) and another 25% were defined as partial PTSD. The full-PTSD group evidenced higher rates of medical utilization, more intense physical symptoms and poorer health functioning than the no-PTSD group. The partial-PTSD group more closely resembled the full-PTSD group. CONCLUSIONS: This study, although limited by sample size and diagnosis by questionnaire vs. diagnostic interview, suggests research directions for enhancing our understanding of PTSD among civilian primary care patients and for developing appropriate interventions that can be conducted in the primary care setting.

Watchful waiting for minor depression in primary care: remission rates and predictors of improvement.

OBJECTIVES: The objectives of this study were to determine remission rates and predictors of improvement for minor depression following a 1-month watchful waiting period in primary care and to describe the watchful waiting processes. METHODS: Prior to randomization into a clinical trial for minor depression, 111 participants were entered into a 1-month watchful waiting period. Depression severity and predictors of improvement were measured at the start of watchful waiting. At the end of watchful waiting, remission rates were calculated and predictor variables were analyzed for their contribution toward predicting improvement. RESULTS: Remission rates were low, ranging from 9% to 13%, depending on the measure. Avoidant coping style and frequency of engaging in active pleasant events at baseline accounted for the majority of change in depression. During watchful waiting, about one fifth of the sample (21%) had at least one contact with their physician and 27% reported using self-initiated treatments. CONCLUSIONS: There is a low likelihood of spontaneous remission for treatment-seeking samples with minor depression in primary care. An avoidant coping style seriously interferes with remission, and engaging in regular active pleasant events confers an advantage. Feasible interventions for primary care that promote activity and decrease avoidant coping styles may improve outcomes. These findings may not generalize to community and non-treatment-seeking samples.

Arthritis pain and disability: response to collaborative depression care.

OBJECTIVE: Collaborative care for depression decreases arthritis pain and disability among older adults, above and beyond mood improvement. This study investigates whether depression management is effective for improving arthritis outcomes across a range of pain severity and activity interference. METHODS: A multi-site randomized-controlled trial (Improving Mood, Providing Access to Collaborative Treatment - IMPACT) identified 1001 participants with both depression and arthritis (mostly osteoarthritis). Depression care managers provided 12 months of systematic depression care [antidepressant pharmacotherapy, and/or problem-solving treatment (PST)] for intervention participants in primary care settings. Control patients received care as usual. Baseline and 12-month interviews assessed arthritis pain severity and activity interference as well as depression, analgesic use, overall functional impairment and coexisting medical conditions. RESULTS: Baseline pain severity showed significant interactions with the intervention on 12-month pain severity (t=2.28, df=68, P=.03) and disability outcomes (t=2.03, df=177, P=.04). Interaction effects of the intervention with baseline activity interference on 12-month pain severity showed a similar trend, but were not statistically significant (t=1.87, df=944, P=.06). CONCLUSIONS: Systematic depression management was more effective than usual care in decreasing pain severity among arthritis patients with lower initial pain severity, but did not have greater benefits than usual care on pain among patients with higher initial pain severity.

Guidelines for conducting geropsychotherapy research.

Geropsychotherapy researchers have established specific methods that improve the reliability and generalizability of the data from this research. To date, there has been little formal dissemination of these methods. The authors present guidelines for the optimal conduct of psychotherapy research in older adults, which include selection of age-appropriate psychotherapies and control conditions, use of consumer-based methods for recruitment, evaluation of age-related treatment processes and outcomes, and adjusting the research design to accommodate age-specific life events and provide examples of how each guideline was used in their psychotherapy studies. Psychotherapy research with older adults has benefited from methodological advances that improve our ability to ascertain the impact of psychotherapy on late-life disorders. However, the field is still in need of better outcome and process measures, methods for measuring the therapeutic content of non-psychotherapy encounters, and methods for determining the impact of choice of treatment on outcome.
