What stakeholders think: perceptions of perinatal depression and screening in China's primary care system.

BACKGROUND: Mental health in China is a significant issue, and perinatal depression has been recognized as a concern, as it may affect pregnancy outcomes. There are growing calls to address China's mental health system capacity issues, especially among vulnerable groups such as pregnant women due to gaps in healthcare services and inadequate access to resources and support. In response to these demands, a perinatal depression screening and management (PDSM) program was proposed. This exploratory case study identified strategies for successful implementation of the proposed PDSM intervention, informed by the Consolidated Framework for Implementation Research (CFIR) framework, in Ma'anshan city, Anhui province. METHODS: This qualitative study included four focus group discussions and two in-depth individual interviews with participants using a semi-structured interview guide. Topics examined included acceptance, utility, and readiness for a PDSM program. Participants included perinatal women and their families, policymakers, and healthcare providers. Interviews were transcribed verbatim, coded, and analyzed for emergent themes. RESULTS: The analysis revealed several promising factors for the implementation of the PDSM program including: utilization of an internet-based platform, generation of perceived value among health leadership and decision-makers, and the simplification of the screening and intervention components. Acceptance of the pre-implementation plan was dependent on issues such as the timing and frequency of screening, ensuring high standards of quality of care, and consideration of cultural values in the intervention design. Potential challenges included perceived barriers to the implementation plan among stakeholders, a lack of trained human health resources, and poor integration between maternal and mental health services. In addition, participants expressed concern that perinatal women might not value the PDSM program due to stigma and limited understanding of maternal mental health issues. CONCLUSION: Our analysis suggests several factors to support the successful implementation of a perinatal depression screening program, guidelines for successful uptake, and the potential use of internet-based cognitive behavioral therapy. PDSM is a complex process; however, it can be successfully navigated with evidence-informed approaches to the issues presented to ensure that the PDSM is feasible, effective, successful, and sustainable, and that it also improves maternal health and wellbeing, and that of their families.

Long versus short pulse width subcallosal cingulate stimulation for treatment-resistant depression: a randomised, double-blind, crossover trial.

BACKGROUND: Stimulation adjustment is required to optimise outcomes of deep brain stimulation (DBS) for treatment-resistant depression, but controlled data for ideal stimulation parameters are poor or insufficient. We aimed to establish the efficacy and safety of short pulse width (SPW) and long pulse width (LPW) subcallosal cingulate DBS in depression. METHODS: We did a double-blind, randomised, crossover trial in an academic hospital in Calgary, AB, Canada. Patients had DSM IV-defined major depressive disorder and bipolar depression (20-70 years old, both sexes) and did not respond to treatment for more than 1 year, with a score of 20 or more on the 17-item Hamilton Depression Rating Scale (HDRS) at recruitment. Patients underwent bilateral DBS implantation into the subcallosal cingulate white matter using diffusion tensor imaging tractography. Patients were randomly assigned 1:1 without stratification using a computerised list generator to receive either SPW (90 µs) or LPW (210-450 µs) stimulation for 6 months. Patients and the clinician assessing outcomes were masked to the stimulation group. Keeping frequency constant (130 Hz), either pulse width or voltage was increased monthly, based on response using the HDRS. Patients who did not respond to treatment (<50% reduction in HDRS from baseline) at 6 months crossed over to the opposite stimulation for another 6 months. All patients received individualised cognitive behavioural therapy (CBT) for 12 weeks. The primary outcome was change in HDRS at 6 months and 12 months using intention-to-treat analysis. This study is registered with ClinicalTrials.gov, NCT01983904. FINDINGS: Between Dec 5, 2013, and Sept 30, 2016, of 225 patients screened for eligibility, 23 patients were selected for DBS surgery. After one patient withdrew, 22 (mean age 46·4 years, SEM 3·1; 10 [45%] female, 12 [55%] male) were randomly assigned, ten (45%) to LPW stimulation and 12 (55%) to SPW stimulation. Patients were followed up at 6 months and 12 months. There was a significant reduction in HDRS scores (p<0·0001) with no difference between SPW and LPW groups (p=0·54) in the randomisation phase at 6 months. Crossover groups did not show a significant decrease in HDRS within groups (p=0·15) and between groups (p=0·21) from 6-12 months. Adverse events were equal between groups. Worsening anxiety and depression were the most common psychological adverse events. One patient in the SPW group died by suicide. INTERPRETATION: Both LPW and SPW stimulation of subcallosal cingulate white matter tracts carried similar risks and were equally effective in reducing depressive symptoms, suggesting a role for both pulse width and amplitude titration in optimising clinical outcomes in patients with treatment-resistant depression.

La versión en español de la Escala Cognitivo-Conductual de Evitación (CBAS) / The Spanish version of the Cognitive-Behavioral Avoidance Scale (CBAS)

Este estudio se propuso evaluar las propiedades psicométricas, validez de constructo y consistencia interna, de la Escala de Evitación Cognitivo-Conductual (CBAS), propuesta originalmente en inglés por Ottenbreit y Dobson (2004). Además pretendía indagar si se confirmaba el modelo estructural hallado por estos autores. 340 estudiantes de ambos sexos (60 hombres y 280 mujeres) de una universidad pública mexicana completaron la CBAS, la Escala de Respuesta de Rumia y al Inventario de Depresión de Beck. Mediante análisis confirmatorio, se confirmó el modelo de afrontamiento de evitación encontrado en estudiantes canadienses con una estructura de cuatro factores relacionados: Conductual/social (CondS), Conductual/no social (CondNS), Cognitivo/social (CogS) y Cognitivo/no social (CogNS), que ajustó satisfactoriamente. Los datos sugieren también la validez de constructo y consistencia interna de la CBAS.

The aim of the present study was to evaluate the psychometric properties, construct validity and internal consistency, of the Spanish version of the Cognitive-Behavioral Avoidance Scale (CBAS), proposed originally in English by Ottenbreit and Dobson (2004). Also, it intended to test if the structural model found by these authors was confirmed. 340 students of a Mexican public university, 60 men and 280 women, completed the CBAS, the Ruminative Response Scale and the Beck Depression Inventory. Using confirmatory factor analysis, the avoidance coping model originally found in Canadian students fit the data, coinciding with the structure of 4 correlated factors: Behavioral Social, Behavioral Nonsocial, Cognitive Social and Cognitive Nonsocial. Construct validity and acceptable internal consistency of the CBAS were also demonstrated.
