Waiting list may be a nocebo condition in psychotherapy trials: a contribution from network meta-analysis

Only little is known regarding the impact of various control conditions on the evidence for effectiveness of psychotherapeutic interventions in randomized controlled trials (RCTs). In their meta-analysis, published in the September issue of Acta Psychiatrica Scandinavica, Furukawa et al. aimed to investigate systematically how three frequently applied control conditions in psychotherapeutic trials (psychological placebo, no treatment, and waiting list) influence the effect sizes for cognitive-behavior therapies (CBT) in acute depression. Altogether 49 RCTs representing 2730 subjects were meta-analyzed using pairwise as well as network meta-analytic statistics. Primary outcome was treatment response in a dichotomous manner.

The meta-analytic results revealed significant superiority of CBT over the “waiting list” and “no treatment” condition, but only a trend when a “psychological placebo” was used in the control group. These findings indicate that the effect sizes for CBT in depression are substantially influenced by the applied control condition. Moreover, the authors found that more participants in the pooled “no treatment“ study group achieved treatment response compared to those allocated to the “waiting list“. Furukawa et al. provided a possible explanation for this interesting result: The patients assigned to a “waiting list“ are possible “more motivated to remain depressive“ in order to receive their originally desired CBT immediately after termination of the RCT, whereas subjects allocated to “no treatment“ may probably more actively seek to receive other therapeutic options to treat their depressive symptoms. The authors concluded that “waiting list” can be regarded even as nocebo condition inferior to the “no treatment” condition.

Fifty years' development and future perspectives of psychiatric register research

In the August issue of Acta Psychiatrica Scandinavica, Munk-Jørgensen and colleagues discuss the past, present and future of register-based psychiatric research. The article is accompanied by editorial comments from Amaddeo (“The small scale clinical psychiatric case registers”) and Stewart (“The big case register”) respectively. In their article, Munk-Jørgensen et al. review the use of psychiatric registers-based research under five subheadings: health service research, outcome studies, identification of representative clinical cohorts, follow-up of clinical cohorts and linkage to biobanks. This provides a useful overview of the types of studies that can be conducted using register-based data. Finally, the inherent strengths/ limitations of register-based research and future directions for the field are comprehensively discussed.

Cognitive deficits in youth with familial and clinical high risk to psychosis: a systematic review and meta-analysis

A high proportion of patients with psychotic disorders are also suffering from cognitive impairment. However, the causal relation between psychosis and cognitive dysfunction remains elusive. In the July issue of Acta Psychiatrica Scandinavica, Bora and colleagues present a large meta-analysis on cognitive deficits in youth with familial and clinical high risk of psychosis. Their findings of increased prevalence of cognitive dysfunction in both groups are consistent with previous literature. Additionally, they report more severe cognitive impairment when these two risk factors are co-occurring. The authors suggest that future research should include more longitudinal studies, in order to identify mechanisms behind this correlation, as well as predictors for the course and outcome of psychotic disorders.

What was learned: studies by the consortium for research in ECT (CORE) 1997-2011

ECT is an effective treatment for severe psychiatric illnesses including unipolar and bipolar depression, psychotic depression, catatonia and delirious mania but remains an underutilized treatment in some countries. In the June issue of Acta Psychiatrica Scandinavica, M. Fink reviews findings from the most comprehensive ECT studies done to date and places them within a historical context. In this review, M. Fink highlights findings in terms of clinical predictors of outcome (e.g. including psychosis, suicide risk, polarity, melancholia, atypical depression and age) and several technical aspects of treatment. The author concludes that ECT is an efficacious treatment for both unipolar and bipolar depression, particularly melancholic or psychotic depression, and rapidly relieves active suicide risk.

SPECIAL ISSUE: A Bipolar Maze: A Roadmap through Translational
Guest Editor, Eduard Vieta

Our publisher Wiley has accepted that we instead of selecting one article as ’article of the month’ present the entire May issue to our readers. This because the May issue entitled “The bipolar maze: a roadmap through translational psychopathology” is a special issue which gives examples of the richness and broadness of today’s bipolar research: epidemiology on age at onset, comorbidity, biomarkers, clinical trial methodology, treatment and medication adherence. The issue is edited by guest editor Professor Eduard Vieta, Barcelona, Spain who has also written the opening editorial: The bipolar maze: a roadmap through translational psychopathology.

A profile approach to impulsivity in bipolar disorder: the key role of strong emotions
L. Muhtadie, S. L. Johnson, C. S. Carver, I. H. Gotlib, T. A. Ketter

Impulsivity is a hallmark symptom of bipolar disorder (BD), and previous research has highlighted its association with illness onset and severity. In the February issue of Acta Psychiatrica Scandinavica, Muhtadie and colleagues present a study designed to test which domains of impulsivity are most informative of clinical severity in BD. The investigators adeptly integrate their findings into the impulsivity and BD literature and also suggest potential targets for therapeutic intervention, including the development of effective emotion regulation and impulse control strategies.

DSM-5 criteria for depression with mixed features: a farewell to mixed depression
A. Koukopoulos n, G. Sani

Throughout its history, the DSM has struggled to categorize mixed forms of mood disorders. With its fifth edition, the DSMproposes a new way to diagnose depression with mixed features. Koukopoulos and Sani’s critique of the DSM-5’s proposed criteria for depression with mixed features in the January issue of Acta Psychiatrica Scandinavica argues that the symptoms that the DSM-5 specifies are neither scientifically nor clinically comprehensive.Koukopoulos and Sanipropose a different set of symptoms which they argue are more clinically adept.
