RESUMEN
BACKGROUND: Increasing interest has centered on the psychotherapeutic working alliance as a means of understanding clinical change in digital mental health interventions in recent years. However, little is understood about how and to what extent a digital mental health program can have an impact on the working alliance and clinical outcomes in a blended (therapist plus digital program) cognitive behavioral therapy (bCBT) intervention for depression. OBJECTIVE: This study aimed to test the difference in working alliance scores between bCBT and treatment as usual (TAU), examine the association between working alliance and depression severity scores in both arms, and test for an interaction between system usability and working alliance with regard to the association between working alliance and depression scores in bCBT at 3-month assessments. METHODS: We conducted a secondary data analysis of the E-COMPARED (European Comparative Effectiveness Research on Blended Depression Treatment versus Treatment-as-usual) trial, which compared bCBT with TAU across 9 European countries. Data were collected in primary care and specialized services between April 2015 and December 2017. Eligible participants aged 18 years or older and diagnosed with major depressive disorder were randomized to either bCBT (n=476) or TAU (n=467). bCBT consisted of 6-20 sessions of bCBT (involving face-to-face sessions with a therapist and an internet-based program). TAU consisted of usual care for depression. The main outcomes were scores of the working alliance (Working Alliance Inventory-Short Revised-Client [WAI-SR-C]) and depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]) at 3 months after randomization. Other variables included system usability scores (System Usability Scale-Client [SUS-C]) at 3 months and baseline demographic information. Data from baseline and 3-month assessments were analyzed using linear regression models that adjusted for a set of baseline variables. RESULTS: Of the 945 included participants, 644 (68.2%) were female, and the mean age was 38.96 years (IQR 38). bCBT was associated with higher composite WAI-SR-C scores compared to TAU (B=5.67, 95% CI 4.48-6.86). There was an inverse association between WAI-SR-C and PHQ-9 in bCBT (B=-0.12, 95% CI -0.17 to -0.06) and TAU (B=-0.06, 95% CI -0.11 to -0.02), in which as WAI-SR-C scores increased, PHQ-9 scores decreased. Finally, there was a significant interaction between SUS-C and WAI-SR-C with regard to an inverse association between higher WAI-SR-C scores and lower PHQ-9 scores in bCBT (b=-0.030, 95% CI -0.05 to -0.01; P=.005). CONCLUSIONS: To our knowledge, this is the first study to show that bCBT may enhance the client working alliance when compared to evidence-based routine care for depression that services reported offering. The working alliance in bCBT was also associated with clinical improvements that appear to be enhanced by good program usability. Our findings add further weight to the view that the addition of internet-delivered CBT to face-to-face CBT may positively augment experiences of the working alliance.

BACKGROUND: Previous research on barriers and facilitators regarding treatment-seeking of adults with depressive and anxiety disorders has been primarily conducted in the Anglosphere. This study aims to gain insight into treatment-seeking behaviour of adults with depressive and anxiety disorders in a European healthcare system. METHODS: In-depth semi-structured interviews were conducted with 24 participants, aged ≥18 years and diagnosed with an anxiety disorder and/or depressive disorder according to DSM-IV. Participants were purposively sampled from an outpatient department for mental health care in the Netherlands. The seven steps of framework analysis were used to identify relevant themes emerging from the interviews. RESULTS: Data analysis suggested an interplay between individual aspects, personal social system, healthcare system and sociocultural context influences. Amongst the most relevant themes were mental health illiteracy, stigma, a negative attitude toward professional help, the influence of significant others and general practitioner, and waiting time. Financial barriers were not of relevance. CONCLUSIONS: Even in a country with a well-developed mental health care system and in absence of financial barriers, there are many barriers to treatment-seeking in adult patients with depressive and anxiety disorders. National campaigns to increase awareness and decrease stigma in the general population, and to empower the social environment might reduce the treatment gap.

OBJECTIVE: To assess the clinical utility of two staging models for bipolar disorder by examining distribution, correlation, and the relationship to external criteria. These are primarily defined by the recurrence of mood episodes (model A), or by intra-episodic functioning (model B). METHODS: In the Dutch Bipolar Cohort, stages according to models A and B were assigned to all patients with bipolar-I-disorder (BD-I; N = 1396). The dispersion of subjects over the stages was assessed and the association between the two models calculated. For both models, change in several clinical markers were concordant with the stage was investigated. RESULTS: Staging was possible in 87% of subjects for model A and 75% for model B. For model A, 1079 participants (93%) were assigned to stage 3c (recurrent episodes). Subdividing stage 3c with cut-offs at 5 and 10 episodes resulted in subgroups containing 242, 510, and 327 subjects. For model B, most participants were assigned to stage II (intra-episodic symptoms, N = 431 (41%)) or stage III (inability to work, N = 451 (43%)). A low association between models was found. For both models, the clinical markers "age at onset," "treatment resistance," and "episode acceleration" changed concordant with the stages. CONCLUSION: The majority of patients with BD-I clustered in recurrent stage 3 of Model A. Model B showed a larger dispersion. The stepwise change in several clinical markers supports the construct validity of both models. Combining the two staging models and sub-differentiating the recurrent stage into categories with cut-offs at 5 and 10 lifetime episodes improves the clinical utility of staging for individual patients.

OBJECTIVE: Bipolar disorder has a wide range of clinical manifestations which may progress over time. The aim of this study was to test the applicability of a clinical staging model for bipolar disorder and to gain insight into the nature of the variables influencing progression through consecutive stages. METHODS: Using retrospectively reported longitudinal life chart data of 99 subjects from the Stanley Foundation Bipolar Network Naturalistic Follow-up Study, the occurrence, duration and timely sequence of stages 2-4 were determined per month. A multi-state model was used to calculate progression rates and identify determinants of illness progression. Stages 0, 1 and several other variables were added to the multi-state model to determine their influence on the progression rates. RESULTS: Five years after onset of BD (stage 2), 72% reached stage 3 (recurrent episodes) and 21% had reached stage 4 (continuous episodes), of whom 8% recovered back to stage 3. The progression from stage 2 to 3 was increased by a biphasic onset for both the depression-mania and the mania-depression course and by male sex. CONCLUSIONS: Staging is a useful model to determine illness progression in longitudinal life chart data. Variables influencing transition rates were successfully identified.

BACKGROUND: Europe's ageing society leads to an increased demand for long-term care, thereby putting a strain on the sustainability of health care systems. The 'Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of Community Care' (IBenC) project aims to develop a new benchmark methodology based on quality of care and cost of care utilization to identify best practices in home care. The study's baseline data, methodology, and rationale are reported. METHODS: Home care organizations in Belgium, Finland, Germany, Iceland, Italy, and the Netherlands, home care clients of 65 years and over receiving home care, and professionals working in these organizations were included. Client data were collected according to a prospective longitudinal design with the interRAI Home Care instrument. Assessments were performed at baseline, after six and 12 months by trained (research) nurses. Characteristics of home care organizations and professionals were collected cross-sectionally with online surveys. RESULTS: Thirty-eight home care organizations, 2884 home care clients, and 1067 professionals were enrolled. Home care clients were mainly female (66.9%), on average 82.9 years (± 7.3). Extensive support in activities of daily living was needed for 41.6% of the sample, and 17.6% suffered cognitive decline. Care professionals were mainly female (93.4%), and over 45 years (52.8%). Considerable country differences were found. CONCLUSION: A unique, international, comprehensive database is established, containing in-depth information on home care organizations, their clients and staff members. The variety of data enables the development of a novel cost-quality benchmark method, based on interRAI-HC data. This benchmark can be used to explore relevant links between organizational efficiency and organizational and staff characteristics.

BACKGROUND: The aim of this study was to explore perceptions of free will in the repetitive behaviors of patients with obsessive-compulsive disorder (OCD) and to explore their relation with core clinical characteristics. METHODS: Experiences of free will were assessed with the Symptomatology And Perceived Free will rating scale (SAPF) in 295 subjects with a lifetime diagnosis of OCD. Patients' scores on the SAPF were subjected to an explorative principal axis factor analysis (PAF). Factor scores were regressed on five OCD symptom dimensions and on seven clinical variables: illness duration, severity of OCD, insight, anxiety and depression, suicidal ideation and quality of life. RESULTS: The PAF revealed three factors: the perceived ability to control and change one's course of action when faced with an obsession or compulsion (the "alternative possibilities" factor); the experience of obsessions or compulsions as intentional (the "intentionality" factor); and the experience of being the source or owner of the obsessions or compulsions (the "ownership" factor). Lower scores on the "alternative possibilities" factor were associated with lower scores on the washing dimension (ß = 0.237, p = 0.004) and higher scores on the precision dimension (ß = - 0.190, p = 0.025) and independently associated with longer illness duration (ß = - 0.134, p = 0.039), higher illness severity (ß = - 0.298, p < 0.001) and lower quality of life (ß = 0.172, p = 0.046). Lower scores on the "intentionality" factor were independently associated with lower quality of life (ß = 0.233, p = 0.027). Higher scores on the "ownership" factor were associated with higher scores on the precision dimension (ß = 0.207, p = 0.023) and independently associated with poorer insight (ß = 0.170, p = 0.045). CONCLUSIONS: The most notable finding of this study is that a diminished experience of free will in OCD is associated with core clinical characteristics: illness duration and severity, insight and quality of life.

BACKGROUND: Evidence suggests that alcohol use and smoking are negatively associated with mood in bipolar disorders (BD). It is unknown if this relationship is moderated by the number of previous mood episodes. Therefore, this paper aims to examine whether the number of previous mood episodes moderates the relationship between alcohol use and smoking, and mood. METHOD: This study assessed the outcomes of 108 outpatients with BD I and II in a prospective observational cohort study. For 1 year, subjects daily registered mood symptoms and substance use with the prospective Life Chart Method. The relationship between the average daily consumption of alcohol and tobacco units in the whole year and mood were examined by multiple linear regression analyses. Number of previous mood episodes, grouped into its quartiles, was added as effect moderator. Outcome was the number of depressive, hypomanic and manic days in that year. RESULTS: The number of depressive days in a year increased by 4% (adjusted ß per unit tobacco = 1.040; 95% CI 1.003-1.079; p = 0.033) per unit increase in average daily tobacco consumption in that same year. Interaction analyses showed that in those subjects with less than 7 previous mood episodes, the number of manic and hypomanic days increased by 100.3% per unit increase in alcohol consumption (adjusted ß per unit alcohol = 2.003; 95% CI 1.225-3.274; p = 0.006). In those with 7 to 13 previous mood episodes, the number of manic and hypomanic days decreased by 28.7% per unit increase in alcohol consumption (adjusted ß per unit alcohol = 0.713; 95% CI 0.539-0.944; p = 0.019); and in subjects with 14 to 44 previous mood episodes, the number of manic and hypomanic days decreased by 7.2% per unit increase in tobacco consumption (adjusted ß per unit tobacco = 0.928; 95% CI 0.871-0.989; p = 0.021). CONCLUSIONS: The number of previous mood episodes moderates the relationship between alcohol use and smoking and mood; and smoking is adversely associated with the number of depressive days.

BACKGROUND: A substantial number of people with bipolar disorder show a suboptimal response to treatment. AIMS: To study the effectiveness of a collaborative care programme on symptoms and medication adherence in patients with bipolar disorder, compared with care as usual. METHOD: A two-armed, cluster randomised clinical trial was carried out in 16 out-patient mental health clinics in The Netherlands, in which 138 patients were randomised. Patient outcomes included duration and severity of symptoms and medication adherence, and were measured at baseline, 6 months and 12 months. Collaborative care comprised contracting, psychoeducation, problem-solving treatment, systematic relapse prevention and monitoring of outcomes. Mental health nurses functioned as care managers in this programme. The trial was registered with The Netherlands Trial Registry (NTR2600). RESULTS: Collaborative care had a significant and clinically relevant effect on number of months with depressive symptoms, both at 6 months (z = -2.6, P = 0.01, d = 0.5) and at 12 months (z = -3.1, P = 0.002, d = 0.7), as well as on severity of depressive symptoms at 12 months (z = -2.9, P = 0.004, d = 0.4). There was no effect on symptoms of mania or on treatment adherence. CONCLUSIONS: When compared with treatment as usual, collaborative care substantially reduced the time participants with bipolar disorder experienced depressive symptoms. Also, depressive symptom severity decreased significantly. As persistent depressive symptoms are difficult to treat and contribute to both disability and impaired quality of life in bipolar disorder, collaborative care may be an important form of treatment for people with this disorder.

OBJECTIVES: Relatively little is known about the temporal relationship between alcohol use and subsequent mood changes in patients with bipolar disorder, and the available findings are inconsistent. The present study was a fine-grained analysis of the temporal relationship between alcohol use and short-term mood-switching probabilities. METHODS: The study included 137 patients with bipolar disorder who performed daily self-ratings of their mood symptoms and the number of alcohol units consumed for a period of up to 52 weeks by using the National Institute of Mental Health self-rated prospective Life Chart Method. At baseline, the Structured Clinical Interview for DSM-IV was administered and demographic, social, and clinical characteristics were obtained. Multi-state models were used to assess the impact of the number of alcoholic drinks on patients' transition through different states of mood (depression, euthymia, and mania). RESULTS: The effect of alcohol use on the change in mood states was limited. For women in a depressive state, higher alcohol use was associated with a shorter time before entering the euthymic state [hazard ratio (HR) = 1.18, 95% confidence interval (CI): 1.03-1.36, p < 0.05], whereas, for men in an euthymic state, higher alcohol use was associated with a longer time before entering a manic state (HR = 0.81, 95% CI: 0.71-0.92, p < 0.05). The correlation between the consumed number of drinks per week and the average mood severity score of the following week was -0.01 (p < 0.001), indicating that only 0.01% of the variance in mood severity in this population is explained by alcohol use. Possible explanations for these findings are discussed. CONCLUSIONS: The current study, using a fine-grained analysis, suggests that alcohol use does not have a direct effect on the course of bipolar disorder in patients using mood stabilizers.

Depression and anxiety occur frequently in pregnancy and may have unfavourable consequences for mother and child. Therefore, adequate symptom measurement seems important. Commonly used instruments are the Center for Epidemiologic Studies Depression Scale (CES-D), the Edinburgh Postpartum Depression Scale (EPDS), and the Hospital Anxiety and Depression Scale, anxiety subscale (HADS-A). We compared the (1) structural and (2) longitudinal validity of these instruments. The data originated from a study on the effectiveness of an Internet intervention for pregnant women with affective symptoms. (1) A confirmatory factor analysis was used to estimate the construct validity. The theoretical factorial structure that was defined in earlier studies of the CES-D and the EPDS, but not the HADS-A, could be sufficiently replicated with acceptable CFI and RMSEA values. (2) Since there were two measurements in time, the hypotheses concerning plausible directions of the change scores of subscales that were (un)related to each other could be formulated and tested. In this way, longitudinal validity in the form of responsiveness was estimated. Ten of sixteen hypotheses were confirmed, corroborating the longitudinal validity of all constructs, except anhedonia, probably due to inconsistent conceptualization. The HADS-A seems less suitable to screen for anxiety in pregnancy. Anhedonia needs better conceptualisation to assess the change of symptoms over time with the CES-D and the EPDS.

Clinicians find it challenging to engage with patients who engage in self-harm. Improving the self-efficacy of professionals who treat self-harm patients may be an important step toward accomplishing better treatment of self-harm. However, there is no instrument available that assesses the self-efficacy of clinicians dealing with self-harm. The aim of this study is to describe the development and validation of the Self-Efficacy in Dealing with Self-Harm Questionnaire (SEDSHQ). This study tests the questionnaire's feasibility, test-retest reliability, internal consistency, content validity, construct validity (factor analysis and convergent validity) and sensitivity to change. The Self-Efficacy in Dealing with Self-Harm Questionnaire is a 27-item instrument which has a 3-factor structure, as found in confirmatory factor analysis. Testing revealed high content validity, significant correlation with a subscale of the Attitude Towards Deliberate Self-Harm Questionnaire (ADSHQ), satisfactory test-retest correlation and a Cronbach's alpha of 0.95. Additionally, the questionnaire was able to measure significant changes after an intervention took place, indicating sensitivity to change. We conclude that the present study indicates that the Self-Efficacy in Dealing with Self-Harm Questionnaire is a valid and reliable instrument for assessing the level of self-efficacy in response to self-harm.

The benefits of rapport between interviewers and respondents, in terms of recruiting the latter and motiving them to participate in research, have been generally endorsed. However, there has been less clarity with regard to the association between rapport and data quality. In theory, rapport could be beneficial if it motivates people to give complete and honest responses. On the other hand, efforts to maintain rapport by exhibiting pleasing and socially desirable behaviour could well be detrimental to data quality. In a large longitudinal epidemiological sample, generalized estimating equations (GEE) analyses were used to examine the association between rapport and the following three quality indicators: missing responses, responses to sensitive questions, and consistency of responses. The results of these analyses indicate an association between a high level of rapport and fewer missing responses. In contrast, we found more socially desirable responses for the high-rapport group. Finally, the high-rapport group did not differ from the low-rapport group in terms of the consistency of their responses.

BACKGROUND: Anxiety and depressive disorders frequently recur, but participation in effective psychological interventions to prevent relapse is limited. The reasons for nonparticipation are largely unknown, hampering successful implementation. The aims of this study were: (1) to investigate reasons why patients with remitted anxiety or depressive disorders refuse cognitive-behavioral therapy relapse prevention interventions (RPIs), (2) to compare these reasons with reasons to participate, and (3) to gain insight into patients' preferences regarding relapse prevention. METHODS: A qualitative study was conducted in which data were gathered from 52 semistructured interviews with patients who either refused or agreed to participate in psychological relapse prevention. The constant comparative method was used. RESULTS: The data showed that those who refused to participate (1) did have knowledge about relapse risks in general, (2) but did not relate this risk to themselves, and therefore, did not feel the need for relapse prevention, or (3) declined to participate for logistical reasons or reasons related to the content of the intervention. Preferences concerning the form and content of RPIs were very diverse. CONCLUSIONS: Psychoeducation on relapse should be provided to patients to help them relate recurrence risks to themselves. RPIs should also be individually tailored.

Objective: To examine the underlying factor structure and psychometric properties of the Assessment of Self-management in Anxiety and Depression (ASAD) questionnaire, which was specifically designed for patients with (chronic) anxiety and depressive disorders. Moreover, this study assesses whether the number of items in the ASAD can be reduced without significantly reducing its precision. Methods: The ASAD questionnaire was completed by 171 participants across two samples: one sample comprised patients with residual anxiety or depressive symptoms, while the other consisted of patients who have been formally diagnosed with a chronic anxiety or depressive disorder. All participants had previously undergone treatment. Both exploratory (EFA) and confirmatory factor analyses (CFA) were conducted. Internal consistency and test-retest reliability were also assessed. Results: Both EFA and CFA indicated three solid factors: Seeking support, Daily life strategies and Taking ownership [Comparative Fit Index = 0.80, Tucker Lewis Index = 0.78, Root Mean Square Error of Approximation = 0.09 (CI 0.08-1.00), Standardized Root Mean Square Residual = 0.09 (χ2 = 439.35, df = 168)]. The ASAD was thus reduced from 45 items to 21 items, which resulted in the ASAD-Short Form (SF). All sub-scales had a high level of internal consistency (> α = 0.75) and test-retest reliability (ICC > 0.75). Discussion: The first statistical evaluation of the ASAD indicated a high level of internal consistency and test-retest reliability, and identified three distinctive factors. This could aid patients and professionals' assessment of types of self-management used by the patient. Given that this study indicated that the 21-item ASAD-SF is appropriate, this version should be further explored and validated among a sample of patients with (chronic or partially remitted) anxiety and depressive disorders. Alongside this, to increase generalizability, more studies are required to examine the English version of the ASAD within other settings and countries.
RESUMEN
BACKGROUND AND RATIONALE: Although it has been suggested that pregnancy may influence the course of bipolar disorder (BD), studies show contradictory results. Until now, no studies included a finegrained validated method to report mood symptoms on a daily basis, such as the lifechart method (LCM). The aim of the present study is to investigate the course of BD during pregnancy by comparing LCM scores of pregnant and non-pregnant women. METHODS: Study design: Comparison of LCM scores of two prospective observational BD cohort studies, a cohort of pregnant women (n = 34) and a cohort of non-pregnant women of childbearing age (n = 52). Main study parameters are: (1) proportions of symptomatic and non-symptomatic days; (2) symptom severity, frequency, and duration of episodes; (3) state sequences, longitudinal variation of symptom severity scores. RESULTS: No differences in clinical course variables (symptomatic days, average severity scores, frequency, and duration of episodes in BD were found between pregnant and non-pregnant women. With a combination of State Sequence Analysis (SSA) and cluster analysis on the sequences of daily mood scores three comparable clusters were found in both samples: euthymic, moderately ill and severely ill. The distribution differences between pregnant and non-pregnant women were significant, with a majority of the pregnant women (68%) belonging to the moderately ill cluster and a majority of the non-pregnant women (46%) to the euthymic cluster. In pregnant women the average daily variation in mood symptoms as assessed with Shannon's entropy was less than in non-pregnant women (respectively 0.43 versus 0.56). CONCLUSIONS: Although the use of daily mood scores revealed no difference in overall course of BD in pregnant versus non-pregnant women, more pregnant than non-pregnant women belonged to the moderately ill cluster, and during pregnancy the variation in mood state was less than in non-pregnant women. Further research is necessary to clarify these findings.
RESUMEN
BACKGROUND: Comorbidity of depressive and anxiety disorders is common and remains incompletely comprehended. This paper summarizes findings from the Netherlands Study of Depression and Anxiety (NESDA) regarding prevalence, temporal sequence, course and longitudinal patterns; sociodemographic, vulnerability and neurobiological indicators; and functional, somatic and mental health indicators of comorbidity. METHODS: Narrative synthesis of earlier NESDA based papers on comorbidity (n=76). RESULTS: Comorbidity was the rule in over three-quarter of subjects with depressive and/or anxiety disorders, most often preceded by an anxiety disorder. Higher severity and chronicity characterized a poorer comorbidity course. Over time, transitions between depressive and anxiety disorders were common. Consistent comorbidity risk indicators in subjects with depressive and anxiety disorders were childhood trauma, neuroticism and early age of onset. Psychological vulnerabilities, such as trait avoidance tendencies, were more pronounced in comorbid than in single disorders. In general, there were few differences in biological markers and neuroimaging findings between persons with comorbid versus single disorders. Most functional, somatic, and other mental health indicators, ranging from disability to cardiovascular and psychiatric multimorbidity, were highest in comorbid disorders. LIMITATIONS: The observational design of NESDA limits causal inference. Attrition was higher in comorbid relative to single disorders. CONCLUSIONS: As compared to single disorders, persons with comorbid depressive and anxiety disorders were characterized by more psychosocial risk determinants, more somatic and other psychiatric morbidities, more functional impairments, and poorer outcome. These results justify specific attention for comorbidity of depressive and anxiety disorders, particularly in treatment settings.

BACKGROUND: No instrumnt exists that can predict the incidence of bipolar disorders (BD). The Bipolarity index (BI), originally developed to improve diagnostic confidence for a lifetime diagnosis of BD, may predict incident BD. AIM: To assess the predictive performance of the BI for incident BD in persons with a lifetime depression. METHODS: The BI score was composed from different questionnaires and interviews in nâ¯=â¯1857 subjects without BD and with a lifetime unipolar depressive disorder from the Netherlands Study of Depression and Anxiety, a longitudinal cohortstudy. The incidence of DSM-IV defined BD I or II as a criterion diagnosis was established with the Composite International Diagnostic Interview after 2, 4, 6 and 9 years of follow-up. Cox regression analyses calculated whether the BI predicts incident BD during 9-years of follow-up. The area Under the Curve (AUC) was determined. At the optimal cut-off score, sensitivity, specificity, positive, and negative predictive values (PPV and NPV) were calculated. RESULTS: Over the course of 9 years, bipolar conversion occurred in nâ¯=â¯46 subjects (2.5%). Each point increase in BI score significantly predicted incident BD (HR[95%CI]= 1.047[1.018-1.076], pâ¯=â¯0.001). The AUC was 0.61 (95%CI: 0.54-0.68). At the optimal cut-off of 30, sensitivity was 67%, specificity 52%, PPV 3% and NPV 98%. LIMITATIONS: Not all items of the BI were fully covered; mean age of the sample of 42. CONCLUSION: The BI score predicts bipolar conversion over 9 years in those with a lifetime depression. However, given the modest performance metrics, the BI cannot guide clinical decision making yet.

Currently, support tools are lacking to prioritize steps in the care coordination process to enable safe practice and effective clinical pathways in the first phase of acute psychiatric admissions. This study describes the development, validity, and reliability of an acute care coordination support tool, the Admission Team Score List (ATSL). The ATSL assists in care provider allocation during admissions. Face validity and feasibility of the ATSL were tested in 77 acute admissions. Endscores of filled out ATSL's were translated to recommended team compositions. These ATSL team (ATSL-T) compositions were compared to the actually present team (AP-T) and the most preferred team (MP-T) composition in hindsight. Consistency between the ATSL-T and the MP-T was substantial; Kw = 0.70, P < 0.001, 95% CI [0.55-0.84]. The consistency between the ATSL-T and AP-T was moderate; Kw = 0.43, P < 0.001, 95% CI [0.23-0.62]. The ATSL has an adequate (inter-rater) reliability; ICC = 0.90, P < 0.001, 95% CI [0.65-0.91]. The ATSL study is an important step to promote safety and efficient care based on care provider allocation, for service users experiencing an acute admission. The ATSL may stimulate structured clinical decision-making during the hectic process around acute psychiatric admissions.

(1) Background: Blended cognitive behavioral therapy (bCBT; online and face-to-face sessions) seems a promising alternative alongside regular face-to-face CBT depression treatment in specialized mental health care organizations. Therapists are key in the uptake of bCBT. This study focuses on therapists' perspectives on usability, satisfaction, and factors that promote or hinder the use of bCBT in routine practice; (2) Methods: Three focus groups (n = 8, n = 7, n = 6) and semi-structured in-depth interviews (n = 15) were held throughout the Netherlands. Beforehand, the participating therapists (n = 36) completed online questionnaires on usability and satisfaction. Interviews were analyzed by thematic analysis; (3) Results: Therapists found the usability sufficient and were generally satisfied with providing bCBT. The thematic analysis showed three main themes on promoting and hindering factors: (1) therapists' needs regarding bCBT uptake, (2) therapists' role in motivating patients for bCBT, and (3) therapists' experiences with bCBT; (4) Conclusions: Overall, therapists were positive; bCBT can be offered by all CBT-trained therapists and future higher uptake is expected. Especially the pre-set structure of bCBT was found beneficial for both therapists and patients. Nevertheless, therapists did not experience promised time-savings-rather, the opposite. Besides, there are still teething problems and therapeutic shortcomings that need improvement in order to motivate therapists to use bCBT.
RESUMEN
BACKGROUND: Mood disorders can be difficult to treat during pregnancy. There is still lack of evidence whether pregnancy influences their natural course and whether continuation of pharmacotherapy, despite potential risks for the unborn child, is beneficial in preventing recurrence of mood episodes during pregnancy. METHODS: Systematic review conducted according to the PRISMA guidelines, searching Pubmed, PsycINFO, Embase and Cochrane databases up till January 9th, 2018. Recurrence rates and various measures of risk were calculated. RESULTS: Out of 1387 articles from an initial search 22 studies met the inclusion criteria. Included studies reported a wide variation in the recurrence rate of bipolar disorder and major depressive disorder during pregnancy (BD: mean = 19%, range = 4%-73%; MDD: mean = 8%, range = 1%-75%). Observational data showed a relative risk reduction of maintenance therapy during pregnancy of 66% in women with BD and 54% for women with MDD, a significant difference (95% CI 9.4-14.6; p < 0.001). LIMITATIONS: heterogeneous samples, study designs, and reported outcomes in included studies. CONCLUSIONS: Despite the importance of the topic there is a paucity of evidence on recurrence rates of mood episodes during pregnancy among women with MDD or BD. Unlike the impact of the postpartum period, it is still uncertain whether the course of mood disorders is influenced by pregnancy. Non-randomized studies show that maintenance pharmacotherapy during pregnancy in women with mood disorders significantly (p < 0.01) reduces the risk of recurrence.
