Self-efficacy and fear of cancer progression during the year following diagnosis of breast cancer

The aim of this study was to investigate fear of disease progression (FoP) during the year following diagnosis of breast cancer and its association with general self‐efficacy (SE).

Class Evolution Tree: A Graphical Tool to Support Decisions on the Number of Classes in Exploratory Categorical Latent Variable Modeling for Rehabilitation Research.

The aim of our study was to develop a graphical tool that can be used in addition to standard statistical criteria to support decisions on the number of classes in explorative categorical latent variable modeling for rehabilitation research. Data from two rehabilitation research projects were used. In the first study, a latent profile analysis was carried out in patients with cancer receiving an inpatient rehabilitation program to identify prototypical combinations of treatment elements. In the second study, growth mixture modeling was used to identify latent trajectory classes based on weekly symptom severity measurements during inpatient treatment of patients with mental disorders. A graphical tool, the Class Evolution Tree, was developed, and its central components were described. The Class Evolution Tree can be used in addition to statistical criteria to systematically address the issue of number of classes in explorative categorical latent variable modeling.

Symptom change trajectories during inpatient psychotherapy in routine care and their associations with long-term outcomes.

This study examined symptom change trajectories during inpatient psychotherapy and the association of these changes with long-term outcomes. In an observational multicenter study, weekly measurements of symptom severity were performed during inpatient treatment and 6 months after discharge. The symptom severity was measured using the 18-item scale of the Hamburg Modules for the Assessment of Psychosocial Health. The sample included 576 inpatients (mean age: 43.9 years; 77.6% female; main diagnoses: depressive (57.2%), adjustment (15.8%), anxiety (7.4%), and eating disorders (7.2%); mean treatment duration: 42.0 days). With empirically and clinically informed growth mixture models four subgroups of symptom change were revealed: gradual response (71%), early response (9%), delayed response (5%), and nonresponse (11%). Particularly low educational level, non-employment and chronic disorders were associated with unfavorable symptom courses (non- and delayed response). Long-term outcomes differed systematically across subgroups (p<0.001; η(2)=0.165). The patients who responded early presented the highest rates of clinically significant improvement (43.9%) from admission to follow-up. Nearly all of these patients (92.7%) showed reliable improvement. Due to the high association of symptom change trajectories with long-term outcomes, results may contribute to interventions that are tailored to the needs of patients and may foster longer lasting therapeutic effectiveness.

Effectiveness of case management as a cross-sectoral healthcare provision for women with breast cancer.

Case management (CM) programs are intended to improve care coordination for cancer patients. This quasi‐experimental, controlled study evaluated whether such a program was effective in improving health‐related quality of life and reducing the psychological distress of breast cancer patients.

Predicting the preferences for involvement in medical decision making among patients with mental disorders

Background The involvement of patients in medical decision making has been investigated widely in somatic diseases. However, little is known about the preferences for involvement and variables that could predict these preferences in patients with mental disorders. Objective This study aims to determine what roles mentally ill patients actually want to assume when making medical decisions and to identify the variables that could predict this role, including patients’ self-efficacy. Method Demographic and clinical data of 798 patients with mental disorders from three psychotherapeutic units in Germany were elicited using self-report questionnaires. Control preference was measured using the Control Preferences Scale, and patients’ perceived self-efficacy was assessed using the Self-Efficacy Scale. Bivariate and multivariate regression analyses were conducted to investigate the associations between patient variables and control preference. Results Most patients preferred a collaborative role (57.5%), followed by a semi passive (21.2%), a partly autonomous (16.2%), an autonomous (2.8%) and a fully passive (2.3%) role when making medical decisions. Age, sex, diagnosis, employment status, medical pretreatment and perceived self-efficacy were associated with the preference for involvement in the multivariate logistic model. Conclusion Our results confirm the preferences for involvement in medical decisions of mentally ill patients. We reconfirmed previous findings that older patients prefer a shared role over an autonomous role and that subjects with a high qualification prefer a more autonomous role over a shared role. The knowledge about predictors may help strengthen treatment effectiveness because matching the preferred and actual role preferences has been shown to improve clinical outcome.

Effectiveness of telephone-based aftercare case management for adult patients with unipolar depression compared to usual care: A randomized controlled trial

Background Patients with depression often have limited access to outpatient psychotherapy following inpatient treatment. The objective of the study was to evaluate the long-term effectiveness of a telephone-based aftercare case management (ACM) intervention for patients with depression. Methods We performed a prospective randomized controlled trial in four psychotherapeutic inpatient care units with N = 199 patients with major depression or dysthymia (F32.x, F33.x, F34.1, according to the ICD-10). The ACM consisted of six phone contacts at two-week intervals performed by trained and certified psychotherapists. The control group received usual care (UC). The primary outcome was depressive symptom severity (BDI-II) at 9-month follow-up, and secondary outcomes were health-related quality of life (SF-8, EQ-5D), self-efficacy (SWE), and the proportion of patients initiating outpatient psychotherapy. Mixed model analyses were conducted to compare improvements between treatment groups. Results Regarding the primary outcome of symptom severity, the groups did not significantly differ after 3 months (p = .132; ES = -0.23) or at the 9-month follow-up (p = .284; ES = -0.20). No significant differences in health-related quality of life or self-efficacy were found between groups. Patients receiving ACM were more likely to be in outpatient psychotherapy after 3 months (OR: 3.00[1.12–8.07]; p = .029) and 9 months (OR: 4.78 [1.55–14.74]; p = .006) than those receiving UC. Conclusions Although telephone-based ACM did not significantly improve symptom severity, it seems to be a valuable approach for overcoming treatment barriers to the clinical pathways of patients with depression regarding their access to outpatient psychotherapy.
