  • Detecting critical decision points in psychotherapy and psychotherapy + medication for chronic depression. Journal of consulting and clinical psychology Steidtmann, D., Manber, R., Blasey, C., Markowitz, J. C., Klein, D. N., Rothbaum, B. O., Thase, M. E., Kocsis, J. H., Arnow, B. A. 2013; 81 (5): 783-792

    Abstract

    Objective: We sought to quantify clinical decision points for identifying depression treatment nonremitters prior to end-of-treatment. Method: Data came from the psychotherapy arms of a randomized clinical trial for chronic depression. Participants (n = 352; 65.6% female; 92.3% White; mean age = 44.3 years) received 12 weeks of cognitive behavioral analysis system of psychotherapy (CBASP) or CBASP plus an antidepressant medication. In half of the sample, receiver operating curve analyses were used to identify efficient percentage of symptom reduction cut points on the Inventory of Depressive Symptoms-Self-Report (IDS-SR) for predicting end-of-treatment nonremission based on the Hamilton Rating Scale for Depression (HRSD). Sensitivity, specificity, predictive values, and Cohen's kappa for identified cut points were calculated using the remaining half of the sample. Results: Percentage of IDS-SR symptom reduction at Weeks 6 and 8 predicted end-of-treatment HRSD remission status in both the combined treatment (Week 6 cut point = 50.0%, Cohen's ? = .42; Week 8 cut point = 54.3%, Cohen's ? = .45) and psychotherapy only (Week 6 cut point = 60.7%, Cohen's ? = .41; Week 8 cut point = 48.7%, Cohen's ? = .49). Status at Week 8 was more reliable for identifying nonremitters in psychotherapy-only treatment. Conclusions: Those with chronic depression who will not remit in structured, time-limited psychotherapy for depression, either with therapy alone or in combination with antidepressant medication, are identifiable prior to end of treatment. Findings provide an operationalized strategy for designing adaptive psychotherapy interventions. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

  • Factors Associated with Clinically Significant Insomnia Among Pregnant Low-Income Latinas JOURNAL OF WOMENS HEALTH Manber, R., Steidtmann, D., Chambers, A. S., Ganger, W., Horwitz, S., Connelly, C. D. 2013; 22 (8): 694-701

    Abstract

    Abstract Background: Poor sleep, common during pregnancy, is associated with negative health risks. The study aimed to identify predictors of clinically significant insomnia among pregnant Latinas. Methods: A total of 1289 pregnant Latinas recruited from obstetric clinics completed the Insomnia Severity Index (ISI) and questions about demographics and sleep. Results: Clinically significant insomnia (ISI?10) was present among 17% of participants. Significant correlates of clinically significant insomnia were higher scores on the Edinburgh Postnatal Depression Scale (EPDS) after removing the sleep item (47% of women with EPDS?9 and 9% with EPDS<9), completing measures in English (rather than Spanish: 26% versus 13%), and income but not pregnancy week, age, highest education level, or marital status. The highest percentage of clinically significant insomnia (59%) was experienced by women with EPDS?9 who completed measures in English. The lowest percentage of clinically significant insomnia (6.2%) was experienced by women with EPDS<9 who completed measures in Spanish. Conclusions: In this sample of low-income, mostly Spanish-speaking pregnant Latinas, rates of clinically significant insomnia appear to be higher than rates among nonpregnant Latinas. Rates of clinically significant insomnia are particularly high among Latinas with elevated depressive symptom severity, a known risk for insomnia. Acculturation, as indicated by completing measures in English, may be another risk specific to Latinas, possibly owing to loss of some ethnicity-specific protective factors (e.g., social support, strong family ties, and group identity). It will be important to directly test this explanation in future research.

  • The Relationship Between the Therapeutic Alliance and Treatment Outcome in Two Distinct Psychotherapies for Chronic Depression. Journal of consulting and clinical psychology Arnow, B. A., Steidtmann, D., Blasey, C., Manber, R., Constantino, M. J., Klein, D. N., Markowitz, J. C., Rothbaum, B. O., Thase, M. E., Fisher, A. J., Kocsis, J. H. 2013

    Abstract

    Objective: This study tested whether the quality of the patient-rated working alliance, measured early in treatment, predicted subsequent symptom reduction in chronically depressed patients. Secondarily, the study assessed whether the relationship between early alliance and response to treatment differed between patients receiving cognitive behavioral analysis system of psychotherapy (CBASP) vs. brief supportive psychotherapy (BSP). Method: 395 adults (57% female; Mage = 46; 91% Caucasian) who met criteria for chronic depression and did not fully remit during a 12-week algorithm-based, open-label pharmacotherapy trial were randomized to receive either 16-20 sessions of CBASP or BSP in addition to continued, algorithm-based antidepressant medication. Of these, 224 patients completed the Working Alliance Inventory-Short Form at Weeks 2 or 4 of treatment. Blind raters assessed depressive symptoms at 2-week intervals across treatment using the Hamilton Rating Scale for Depression. Linear mixed models tested the association between early alliance and subsequent symptom ratings while accounting for early symptom change. Results: A more positive early working alliance was associated with lower subsequent symptom ratings in both the CBASP and BSP, F(1, 1236) = 62.48, p < .001. In addition, the interaction between alliance and psychotherapy type was significant, such that alliance quality was more strongly associated with symptom ratings among those in the CBASP treatment group, F(1, 1234) = 8.31, p = .004. Conclusions: The results support the role of the therapeutic alliance as a predictor of outcome across dissimilar treatments for chronic depression. Contrary to expectations, the therapeutic alliance was more strongly related to outcome in CBASP, the more directive of the 2 therapies. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

  • Antenatal identification of major depressive disorder: a cohort study AMERICAN JOURNAL OF OBSTETRICS AND GYNECOLOGY Lyell, D. J., Chambers, A. S., Steidtmann, D., Tsai, E., Caughey, A. B., Wong, A., Manber, R. 2012; 207 (6)

    Abstract

    The purpose of this study was to estimate the frequency of identification of major depressive disorder by providers during prenatal care.A cohort of pregnant women who were participating in a randomized controlled trial and who had received a diagnosis of major depressive disorder was examined. Women were included in the current study if prenatal clinic records were available and legible.Clinical depression was noted in 56% of prenatal charts and on 24% of problem lists. Physicians and certified nurse midwives noted depression equally (P = .935); physicians more frequently noted mental health referral (23% vs 0%; P = .01), and midwives more frequently included depression on the problem list (P = .01). Recent medication use, which was stopped before conception or study participation, predicted notation of depression in the chart (P = .001).Depression frequently is missed during pregnancy and, when identified, is underacknowledged as a problem. Women who have not recently used antidepressant medication are more likely to be missed. Better screening and acknowledgment are needed.

  • PATIENT TREATMENT PREFERENCE AS A PREDICTOR OF RESPONSE AND ATTRITION IN TREATMENT FOR CHRONIC DEPRESSION DEPRESSION AND ANXIETY Steidtmann, D., Manber, R., Arnow, B. A., Klein, D. N., Markowitz, J. C., Rothbaum, B. O., Thase, M. E., Kocsis, J. H. 2012; 29 (10): 896-905

    Abstract

    Findings regarding the relationship between patient treatment preference and treatment outcome are mixed. This is a secondary data analysis investigating the relationship between treatment preference, and symptom outcome and attrition in a large two-phase depression treatment trial.Patients met DSM-IV criteria for chronic forms of depression. Phase I was a 12-week, nonrandomized, open-label trial in which all participants (n = 785) received antidepressant medication(s) (ADM). Phase I nonremitters were randomized to Phase II, in which they received 12 weeks of either cognitive-behavioral system of psychotherapy (CBASP) + ADM (n = 193), brief supportive psychotherapy (BSP) + ADM (n = 187), or ADM only (n = 93). Participants indicated their treatment preference (medication only, combined treatment or no preference) at study entry. Symptoms were measured at 2-week intervals with the 24-item Hamilton Rating Scale for Depression (HAM-D).A large majority of patients reported a preference for combined treatment. Patients who preferred medication only were more likely to endorse a chemical imbalance explanation for depression, whereas those desiring combined treatment were more likely to attribute their depression to stressful experiences. In Phase I, patients who expressed no treatment preference showed greater rates of HAM-D symptom reduction than those with any preference, and patients with a preference for medication showed higher attrition than those preferring combined treatment. In Phase II, baseline treatment preference was not associated with symptom reduction or attrition.Treatment preferences may moderate treatment response and attrition in unexpected ways. Research identifying factors associated with differing preferences may enable improved treatment retention and response.

  • Comparative data on child and adolescent cognitive measures associated with depression JOURNAL OF CONSULTING AND CLINICAL PSYCHOLOGY Ingram, R. E., Nelson, T., Steidtmann, D. K., Bistricky, S. L. 2007; 75 (3): 390-403

    Abstract

    As a way to better understand the effects of treatment for depression, comparative data on measures of cognition have been compiled previously for adults. Such data should be able to aid the evaluation of cognition and cognitive change, and may provide valuable information for clinicians and researchers alike. In this article, analogous comparative data on cognitive measures associated with depression in children and adolescents are presented. The reviewed instruments assess cognitive errors, attributional style, dysfunctional attitudes, hopelessness, negative self-statements, and Beck's negative cognitive triad. As with adults, these data may have implications for enhancing understanding of empirically supported treatments for children and adolescents, may be useful in vulnerability research, and may be useful to clinicians seeking to develop treatment strategies and to gauge treatment effectiveness.
