RESUMO

OBJECTIVE: Determine predictors of reduced worry and anxiety for older adults participating in the pilot phase of Calmer Life, a modular, personalized cognitive-behavioral treatment for worry. METHODS: Underserved adults (N = 54) over age 50 participated. Therapists were either experts (Ph.D. or Master's) or nonexpert providers (case managers, community health workers, and bachelor's level). Participants completed the Penn State Worry Questionnaire-Abbreviated (PSWQ-A) and the Geriatric Anxiety Inventory-Short Form (GAI-SF) before treatment and at 3 months. RESULTS: Demographic and clinical variables were individually entered into separate regression equations, controlling for pretreatment scores, to determine their associations with post-treatment 1) PSWQ-A and 2) GAI-SF scores. Only younger age and African American race were significant (p < .05) univariate predictors of higher post-treatment PSWQ-A scores. African American race was also a significant predictor of higher post-treatment GAI-SF scores. CONCLUSIONS: African American participants had higher post-treatment PSWQ-A and GAI-SF scores than White and Hispanic participants. Younger age was also associated with more severe PSWQ-A post-treatment scores. CLINICAL IMPLICATIONS: Younger participants may experience additional stressors (e.g., caregiving, working) compared with older participants. Smaller decreases in anxiety in African Americans point to the need for continued focus and additional modification of interventions.

RESUMO

OBJECTIVES: Rural, homebound older adults are at increased risk for anxiety and depression and have limited access to mental health services. These individuals face many barriers to receiving evidence-based mental health treatment and would benefit from interventions that increase access to and efficiency of care. The aim of this study was to evaluate use of a telephone-delivered, modular, cognitive behavioral therapy (CBT) intervention for both late-life depression and anxiety delivered to rural, homebound Veterans. METHODS: Three cases are presented to illustrate the flexible adaptation of the intervention for use among older Veterans enrolled in home-based primary care, with varying symptom presentations and functional limitations. The Veterans received 7 to 9 sessions of the CBT intervention, with ordering of skill modules based on symptom presentation and determined collaboratively between patient and therapist. RESULTS: The three Veterans showed improvement in depression and/or anxiety symptoms following treatment and provided positive feedback regarding their experiences in this program. CONCLUSIONS: These results suggest that telephone-delivered CBT is acceptable to older adults and can be tailored to individual patient needs. CLINICAL IMPLICATIONS: Clinicians should consider telephone-delivered CBT as an alternate mode of therapy to increase access to mental health care for rural, homebound individuals with depression and anxiety.

RESUMO

OBJECTIVES: To evaluate the feasibility of the Calmer Life and Enhanced Community Care interventions delivered by community and expert providers and test their preliminary effectiveness on worry, generalized anxiety disorder (GAD) severity, anxiety, depression, sleep, health-related quality of life, and satisfaction. DESIGN: Small randomized trial, with measurements at baseline and 3 months. SETTING: Underserved, low-income, mostly minority communities in Houston, TX. PARTICIPANTS: Forty underserved adults 50 years and older, with significant worry and principal or coprincipal GAD or anxiety disorder not otherwise specified. INTERVENTION: Combination of person-centered, flexible skills training to reduce worry; resource counseling to target unmet basic needs; and facilitation of communication with primary care providers developed through a community-academic partnership with social service and faith-based organizations. Religion/spirituality may be incorporated. PRIMARY OUTCOMES: worry (Penn State Worry Questionnaire-Abbreviated), GAD severity (GAD-7), anxiety (Geriatric Anxiety Inventory-Short Form). SECONDARY OUTCOMES: depression (Patient Health Questionnaire-8 and Geriatric Depression Scale-Short Form), sleep (Insomnia Severity Index), health-related quality of life (12-item Medical Outcomes Study Short Form), satisfaction (Client Satisfaction Questionnaire and exit interviews). RESULTS: Provider training was valid; mean ratings for community providers were well above average, with none less than adequate. Reach was excellent. Participants receiving the Calmer Life intervention had greater improvement in GAD severity and depression than those receiving Enhanced Community Care. Satisfaction with both treatments was equivalent. CONCLUSIONS: A larger comparative-effectiveness trial needs to examine outcomes following the Calmer Life intervention relative to standard community-based care and to evaluate more fully issues of implementation potential.

RESUMO

OBJECTIVES: To assist researchers and clinicians considering using the Santa Clara Strength of Religious Faith Questionnaire (SCSRFQ) with older-adult samples, the current study analyzed the psychometrics of SCSRFQ scores in two older-adult samples. METHOD: Adults of age 55 or older who had formerly participated in studies of cognitive-behavioral therapy for anxiety and/or depression were recruited to complete questionnaires. In Study 1 (N = 66), the authors assessed the relations between the SCSRFQ and other measures of religiousness/spirituality, mental health, and demographic variables, using bivariate correlations and nonparametric tests. In Study 2 (N = 223), the authors also conducted confirmatory and exploratory factor analyses of the SCSRFQ, as well as an item response theory analysis. RESULTS: The SCSRFQ was moderately to highly positively correlated with all measures of religiousness/spirituality. Relations with mental health were weak and differed across samples. Ethnic minorities scored higher than White participants on the SCSRFQ, but only in Study 2. Factor analyses showed that a single-factor model fit the SCSRFQ best. According to item response theory analysis, SCSRFQ items discriminated well between participants with low-to-moderate levels of the construct but provided little information at higher levels. CONCLUSION: Although the SCSRFQ scores had adequate psychometric characteristics, the measure's usefulness may be limited in samples of older adults.

RESUMO

Increasing numbers of patients are treated in integrated primary care mental health programs. The current study examined predictors of satisfaction with treatment in patients from a randomized clinical trial of late-life generalized anxiety disorder (GAD) in primary care. Higher treatment satisfaction was associated with receiving CBT rather than enhanced usual care. Treatment credibility, treatment expectancies, social support, and improvements in depression and anxiety symptoms predicted higher treatment satisfaction in the total sample. In the CBT group, only credibility and adherence with treatment predicted satisfaction. This suggests that older patients receiving CBT who believe more strongly in the treatment rationale and follow the therapist's recommendations more closely are likely to report satisfaction at the end of treatment. In addition, this study found that adherence mediated the relationship between treatment credibility and treatment satisfaction. In other words, patients' perceptions that the treatment made sense for them led to greater treatment adherence which then increased their satisfaction with treatment.

RESUMO

BACKGROUND: Despite the availability of evidence-based psychotherapies for depression and anxiety, they are underused in non-mental health specialty settings such as primary care. Hybrid effectiveness-implementation designs have the potential to evaluate clinical and implementation outcomes of evidence-based psychotherapies to improve their translation into routine clinical care practices. METHODS: This protocol article discusses the study methodology and implementation strategies employed in an ongoing, hybrid, type 2 randomized controlled trial with two primary aims: (1) to determine whether a brief, manualized cognitive behavioral therapy administered by Veterans Affairs Primary Care Mental Health Integration program clinicians is effective in treating depression and anxiety in a sample of medically ill (chronic cardiopulmonary diseases) primary care patients and (2) to examine the acceptability, feasibility, and preliminary outcomes of a focused implementation strategy on improving adoption and fidelity of brief cognitive behavioral therapy at two Primary Care-Mental Health Integration clinics. The study uses a hybrid type 2 effectiveness/implementation design to simultaneously test clinical effectiveness and to collect pilot data on a multifaceted implementation strategy that includes an online training program, audit and feedback of session content, and internal and external facilitation. Additionally, the study engages the participation of an advisory council consisting of stakeholders from Primary Care-Mental Health Integration, as well as regional and national mental health leaders within the Veterans Administration. It targets recruitment of 320 participants randomized to brief cognitive behavioral therapy (n = 200) or usual care (n = 120). Both effectiveness and implementation outcomes are being assessed using mixed methods, including quantitative evaluation (e.g., intent-to-treat analyses across multiple time points) and qualitative methods (e.g., focus interviews and surveys from patients and providers). Patient-effectiveness outcomes include measures of depression, anxiety, and physical health functioning using blinded independent evaluators. Implementation outcomes include patient engagement and adherence and clinician brief cognitive behavioral therapy adoption and fidelity. CONCLUSIONS: Hybrid designs are needed to advance clinical effectiveness and implementation knowledge to improve healthcare practices. The current article describes the rationale and challenges associated with the use of a hybrid design for the study of brief cognitive behavioral therapy in primary care. Although trade-offs exist between scientific control and external validity, hybrid designs are part of an emerging approach that has the potential to rapidly advance both science and practice.

RESUMO

BACKGROUND: Patients with diabetes are at increased risk for depression, compounding the burden of disease. When comorbid with diabetes, depression leads to poorer health outcomes and often complicates diabetes self-management. Unfortunately, treatment options for these complex patients are limited and comprehensive services are rarely available for patients in rural settings. METHODS: A small open trial was conducted to test the acceptability, feasibility and preliminary outcomes of a telephone-delivered coaching intervention for rural-dwelling older adults with uncontrolled diabetes and comorbid, clinically significant depressive symptoms. A total of eight older adults were enrolled in Healthy Outcomes through Patient Empowerment (HOPE), a 10-session (12-week), telephone-based coaching intervention. Primary study constructs included measures of diabetes control (Hemoglobin [Hb] A1c), depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]), and diabetes-related distress (Problem Areas in Diabetes Scale [PAID]). Assessments were conducted at baseline, post-intervention, and 6-month follow-up. Acceptability and feasibility were evaluated using patient surveys, focused exit interviews, and session attendance data. RESULTS: Clinically significant improvements were realized post-intervention and at 6-month follow-up for outcomes related to diabetes and depression. Effect sizes using Cohen's d were determined post-intervention and at 6-month follow-up, respectively, for HbA1c (d=0.36; d=0.28), PHQ-9 (d=1.48; d=1.67, and PAID (d=1.50; d=1.06) scores. Among study participants, HbA1c improved from baseline by a mean (M) of 1.13 (SD=1.70) post-intervention and M=0.84 (SD=1.62) at 6 months. Depression scores, measured by the PHQ-9, improved from baseline by M=5.14 (SD=2.27) post-intervention and M=7.03 (SD=4.43) at 6-month follow-up. PAID scores also improved by M=17.68 (SD=10.7) post-intervention and M=20.42 (SD=20.66) from baseline to 6-month follow-up. Case examples are provided for additional context and to more fully articulate salient intervention concepts. CONCLUSION: Although preliminary, data from this small open trial suggest that HOPE holds the potential to improve both physical (diabetes) and emotional (diabetes distress, depression) health outcomes and that changes can be maintained over a 6-month time period. As envisioned by the authors, HOPE may function as an extension of traditional primary care for rural-dwelling older adults with multiple comorbidities. A future randomized clinical trial will test HOPE's broader effectiveness with rural-dwelling older adults. TRIAL REGISTRATION: NCT01274715.

RESUMO

The Pittsburgh Sleep Quality Index (PSQI) is a widely used, comprehensive self-report measure of sleep quality and impairment, which has demonstrated good psychometric properties within various populations, including older adults. However, the psychometric properties of the PSQI and its component scores have not been evaluated for older adults with generalized anxiety disorder (GAD). Additionally, changes in PSQI global or component scores have not been reported following cognitive-behavioral treatment (CBT) of late-life GAD. This study examined (1) the psychometric properties of the PSQI within a sample of 216 elderly primary care patients age 60 or older with GAD who were referred for treatment of worry and/or anxiety; as well as (2) response to CBT, relative to usual care, for 134 patients with principal or coprincipal GAD. The PSQI demonstrated good internal consistency reliability and adequate evidence of construct validity. Those receiving CBT experienced greater reductions in PSQI global scores at post-treatment, relative to those receiving usual care. Further, PSQI global and component scores pertaining to sleep quality and difficulties falling asleep (i.e., sleep latency and sleep disturbances) demonstrated response to treatment over a 12-month follow-up period. Overall, results highlight the usefulness of the PSQI global and component scores for use in older adults with GAD.

RESUMO

Parkinson's disease (PD) is the second most common neurodegenerative disorder. It is generally defined by its progressive motor features; but increased attention is being paid to its non-motor neuropsychiatric symptoms, which profoundly impact quality of life for patients and caregivers. Anxiety and depression are particularly problematic and are the strongest predictors of quality of life in PD. Recent research has focused on non-pharmacological approaches to treating depression and anxiety in patients with PD. Cognitive-behavioral therapy (CBT) is a potentially efficacious non-pharmacological treatment for mood and anxiety symptoms associated with PD. Accordingly, this review examines empirical studies of CBT-based treatments for depression and anxiety symptoms in PD. Medical Subject Headings were used in searches of PsychInfo and PubMed of English-language articles published in peer-reviewed journals, resulting in the identification of 10 articles. Four additional articles were identified from the references of these articles and upon the suggestions of experts, for 15 articles in all. Results of individual studies varied significantly; however, the randomized controlled trials showed encouraging results and support the need for further investigation of the utility of CBT for depressed and anxious patients with PD. CBT is potentially a useful treatment for patients with PD and comorbid depression and/or anxiety, but more systematic research will be necessary to measure its effects.

RESUMO

OBJECTIVE: Major depression is the most common psychiatric disorder among breast cancer patients and is associated with substantial impairment. Although some research has explored the utility of psychotherapy with breast cancer patients, only 2 small trials have investigated the potential benefits of behavior therapy among patients with well-diagnosed depression. METHOD: In a primarily Caucasian, well-educated sample of women (age = 55.4 years, SD = 11.9) diagnosed with breast cancer and major depression (n = 80), this study was a randomized clinical trial testing the efficacy of 8 sessions of behavioral activation treatment for depression (BATD) compared to problem-solving therapy. Primary outcome measures assessed depression, environmental reward, anxiety, quality of life, social support, and medical outcomes. RESULTS: Across both treatments, results revealed strong treatment integrity, excellent patient satisfaction with treatment protocols, and low patient attrition (19%). Intent-to-treat analyses suggested both treatments were efficacious, with both evidencing significant pre-post treatment gains across all outcome measures. Across both treatments, gains were associated with strong effect sizes, and based on response and remission criteria, a reliable change index, and numbers-needed-to-treat analyses, approximately ¾ of patients exhibited clinically significant improvement. No significant group differences were found at posttreatment. Treatment gains were maintained at 12-month follow-up, with some support for stronger maintenance of gains in the BATD group. CONCLUSIONS: BATD and problem-solving interventions represent practical interventions that may improve psychological outcomes and quality of life among depressed breast cancer patients. Study limitations and future research directions are discussed.

RESUMO

Major depression is the most common psychiatric disorder among cancer patients and is associated with decreased quality of life, significant deterioration in recreational and physical activities, relationship difficulties, sleep problems, more rapidly progressing cancer symptoms, and more metastasis and pain relative to nondepressed cancer patients. Although some research has explored the utility of psychological interventions with cancer patients, only one study to date has explored the potential benefits of cognitive-behavior therapy among cancer patients with well-diagnosed depression. Addressing this gap in the literature, this study represents an open clinical trial to assess the effectiveness of a brief Cognitive-Behavioral Treatment for Depression (CBTD) among depressed cancer patients in a medical care setting. Results revealed strong treatment integrity, good patient compliance, excellent patient satisfaction with the CBTD protocol, and significant pre-post treatment gains across a breadth of outcome measures assessing depression, anxiety, quality of life, and medical outcomes. These gains also were associated with strong effect sizes and generally maintained at 3-month follow-up. Behavioral activation interventions, especially when paired with cognitive techniques, may represent a practical medical care treatment that may improve psychological outcomes and quality of life among cancer patients. Study limitations and future research directions are discussed.

RESUMO

Clinical depression is the most common psychiatric disorder among cancer patients and is associated with significant functional impairment. Unfortunately, depression in cancer patients is often under- diagnosed and untreated, and studies examining the predictive utility of assessment instruments in detecting clinically depressed cancer patients are sparse. Using a structured interview, thirty-three patients with various cancer types were diagnosed as having major depression (n = 24) or no psychiatric diagnosis (n = 9). All patients were administered the Beck Depression Inventory-II (BDI-II), the Center for Epidemiological Studies in Depression Scale (CES-D), Hamilton Rating Scale for Depression (HRSD), Quality of Life Inventory (QOLI), a medical and psychosocial functioning questionnaire (SF-36), and given co-morbidity of depression with anxiety disorders, the Beck Anxiety Inventory (BAI). Depressed and non-depressed cancer patients were compared and contrasted across all assessment measures and accuracy of instruments was based on evaluating their sensitivity, specificity, and positive predictive values. Depressed cancer patients exhibited more severe depressive symptoms and poorer quality of life, increased anxiety and bodily pain, and decreased vitality and social functioning. All instruments exhibited strong predictive properties, with the CES-D and BDI-II considered most feasible given their time efficiency, administrative simplicity, and strong psychometric properties.

RESUMO

Researchers acknowledge a strong association between the frequency and duration of environmental reward and affective mood states, particularly in relation to the etiology, assessment, and treatment of depression. Given behavioral theories that outline environmental reward as a strong mediator of affect and the unavailability of an efficient, reliable, and valid self-report measure of environmental reward, we developed the Environmental Reward Observation Scale (EROS) and examined its psychometric properties. In Experiment 1, exploratory factor analysis supported a unidimensional 10-item measure with strong internal consistency and test-retest reliability. When administered to a replication sample, confirmatory factor analysis suggested an excellent fit to the 1-factor model and convergent/discriminant validity data supported the construct validity of the EROS. In Experiment 2, further support for the convergent validity of the EROS was obtained via moderate correlations with the Pleasant Events Schedule (PES; MacPhillamy & Lewinsohn, 1976). In Experiment 3, hierarchical regression supported the ecological validity of the EROS toward predicting daily diary reports of time spent in highly rewarding behaviors and activities. Above and beyond variance accounted for by depressive symptoms (BDI), the EROS was associated with significant incremental variance in accounting for time spent in both low and high reward behaviors. The EROS may represent a brief, reliable and valid measure of environmental reward that may improve the psychological assessment of negative mood states such as clinical depression.

RESUMO

Although the Revised Cheek and Buss Shyness Scale (RCBS; Cheek, 1983) is widely used, its psychometric properties largely are unknown. In this investigation, we examined the normative data, factor structure, internal consistency, test-retest reliability, and convergent/discriminant validity of the RCBS using a sample of 261 university students. Results provided strong support for the stability of normative data over time, reliability of the measure, and its predicted associations with contemporary measures of shyness, social anxiety, and related constructs. Although support was obtained for a unifactorial conceptualization of shyness, an exploratory factor analysis revealed an alternative 3-factor solution that was supportive of a previously proposed meta-analytic model of shyness (Jones, Briggs, & Smith, 1986) and was consistent with other prominent shyness theories (Buss, 1980; Pilkonis, 1977a, 1977b; Zimbardo, 1977). This factor model was replicable on a holdout sample, and there were some data to support the discriminant validity of factors.

RESUMO

Pigeons accustomed to food reinforcement for responding in the presence of a 25-Hz flickering light were exposed to several sets of flicker-frequency stimuli arranged as increasing and decreasing series. In the first experiment, food was occasionally delivered for key pecks during 30-s periods of 25-Hz flicker appearing at the beginning, midway, and at the end of an ascending and descending series of nine frequencies, ranging from 13 to 37 Hz. These stimuli appeared for 15-s periods with no food available (extinction). Gradients of responding to flicker values in the ascending series differed from those in the descending series, showing displacements in peak responding toward the lower and higher frequency values, respectively. The same effects occurred when the sequence was changed so that a descending series was followed by an ascending series of frequencies. These effects are consonant with an adaptation level (AL) interpretation and were replicated in a second experiment in which durations of the extinction presentations were increased to 30s. In a final condition, only a descending series was presented and displacement of peak responding from 25 Hz to a higher frequency stimulus, 28 Hz, was observed.

RESUMO

Recent data has sparked renewed interest in behavioral treatments for depression; however several fundamental questions remain regarding the mechanisms of such approaches. To this end, the current study directly tested the assumption that non-clinical mildly depressed individuals receive less response-contingent positive reinforcement than non-depressed individuals, indicated by less engagement in behaviors perceived as rewarding in terms of both immediate pleasure and potential for these behaviors to result in more distal rewards. The data presented support this assumption and provide support for the role of reinforcement-based strategies such as behavioral activation in the treatment of depression.
