The effects of SmartCare© on neuro-oncology family caregivers' distress: a randomized controlled trial.

PURPOSE: Patients with primary malignant brain tumors have high symptom burden and commonly rely on family caregivers for practical and emotional support. This can lead to negative mental and physical consequences for caregivers. We investigated effectiveness of an 8-week nurse-led online needs-based support program (SmartCare©) with and without online self-guided cognitive behavioral therapy (CBT) for depression compared to enhanced care as usual (ECAU) on depressive symptoms, caregiving-specific distress, anxiety, mastery, and burden. METHODS: Family caregivers scoring ≥ 6 on a depressive symptoms inventory were randomized to three groups: ECAU plus self-guided CBT and SmartCare©; ECAU plus SmartCare©; ECAU only. Primary outcomes (depressive symptoms; caregiving-specific distress) and secondary outcomes (anxiety, caregiver mastery, and caregiver burden) were assessed online. Intention to treat (ITT) and per protocol (PP) analyses of covariance corrected for baseline scores were performed for outcomes at 4 months. RESULTS: In total, 120 family caregivers participated. Accrual and CBT engagement were lower than expected, therefore intervention groups were combined (n = 80) and compared to ECAU (n = 40). For depressive symptoms, no statistically significant group differences were found. Caregiving-specific distress decreased in the intervention group compared with ECAU (ITT: p = 0.01, partial ɳ2 = 0.08; PP: p = 0.02, partial ɳ2 = 0.08). A trend towards improvement in mastery for the intervention group compared with ECAU was identified (ITT: p = 0.08, partial ɳ2 = 0.04; PP: p = 0.07, partial ɳ2 = 0.05). CONCLUSIONS: SmartCare©, with or without self-guided CBT, reduced caregiving-specific distress with a trend towards improving mastery. SmartCare© has the potential to improve the lives of families coping with a brain tumor diagnosis. TRIAL REGISTRATION NUMBER: NCT02058745; 10 February 2014.

Family caregivers' level of mastery predicts survival of patients with glioblastoma: A preliminary report.

BACKGROUND: Glioblastoma multiforme (GBM) is associated with a poor prognosis, and patients rely heavily on family caregivers for physical and emotional support. The capability and mental health of family caregivers may influence their ability to provide care and affect patient outcomes. The objective of the current study was to investigate whether caregivers' anxiety, depressive symptoms, burden, and mastery influenced survival in a sample of patients newly diagnosed with GBM. METHODS: Baseline data from caregiver-patient dyads participating in a longitudinal study funded by the National Institutes of Health were used. Cox regression analyses were performed to determine whether caregiver anxiety (Profile of Mood States-Anxiety), depressive symptoms (Center for Epidemiologic Studies-Depression Scale), burden (Caregiver Reaction Assessment), and feelings of mastery (Mastery Scale) predicted the survival time of patients with GBM after controlling for known covariates (patient age, Karnofsky performance status, type of surgery, and postsurgical treatment). RESULTS: A total of 88 caregiver-patient dyads were included. The median overall survival for the sample was 14.5 months (range, 0-88 months). After controlling for covariates, caregiver mastery was found to be predictive of patient survival. With each unit increase in mastery, there was a 16.1% risk reduction in patient death (95% confidence interval, 0.771-0.913; P<.001). CONCLUSIONS: To the authors' knowledge, the results of the current study are among the first to explore the impact of family caregiving on the outcomes of patients with GBM. If these results are supported in other studies, providing neuro-oncology caregivers with more structured support and guidance in clinical practice has the potential to improve caregivers' feelings of mastery, thereby influencing patients' well-being for the better.

Locke-Wallace Short Marital-Adjustment Test: psychometric evaluation in caregivers for persons with primary malignant brain tumor.

BACKGROUND AND PURPOSE: Caregivers' well-being has been found to be associated with marital adjustment. This study's purpose was to evaluate the psychometric properties of the Locke-Wallace Short Marital-Adjustment Test (LWSMAT) in a sample of caregivers of persons with primary malignant brain tumor (PMBT). METHODS: Secondary analysis of data collected from 114 caregivers. The LWSMAT was tested for factor structure, internal consistency reliability, and construct validity. RESULTS: 5 extracted factors explained 60.55% of the total variance. Four interpretable factors (Contentment & Communication, Leisure & Sociality, Intimacy, and Shared Philosophy) had Cronbach's alpha between 0.63 and 0.74. Convergent validity (r = -.35 and r = -.43, respectively, both p < .0001) and discriminant validity (r = .07, p = .49; and r = -.04, p = .67) were confirmed by comparing four factors with subdimensions of the Caregiver Reaction Assessment (CRA). CONCLUSION: The LWSMAT is a multidimensional, reliable, and valid measure of marital adjustment in caregivers of persons with a PMBT.

Branded versus generic clozapine for treatment of schizophrenia.

OBJECTIVE: To report clinical findings resulting from a switch from branded to generic clozapine. METHODS: Twenty patients diagnosed with schizophrenia were followed in this naturalistic outpatient study. The Positive and Negative Syndrome Scale (PANSS), Beck Anxiety Inventory (BAI), Abnormal Involuntary Movement Scale, and the Movement Disorder Assessment were used to assess differences in the clinical status of patients before and after switching from Clozaril to generic clozapine (Mylan Pharmaceuticals). Results were analyzed by means of the paired t-test and by calculation of the percent change in mean scores. A clinically significant change as measured by the PANSS was defined as a +/- 20% change in mean scores at final evaluation. The design was open-label and non-blinded. RESULTS: At the final evaluation, the t-test revealed no significant differences between branded and generic clozapine for the total PANSS, the positive symptom, negative symptom, and the general psychopathology subscales of the PANSS, and the BAI. There were no clinically significant changes for any measure. CONCLUSIONS: In this small group of patients with schizophrenia, no deterioration in clinical status in several domains was noted after changing from branded to generic clozapine. This finding is consistent with pharmacologic data suggesting bioequivalence of the 2 products. Results, however, must be interpreted cautiously due to the lack of optimal study controls and small sample size.
