Randomized Controlled Trial Multicenter StudyModerating effect of comorbid anxiety disorders on treatment outcome in a randomized controlled psychotherapy trial in early-onset persistently depressed outpatients.
Persistent depressive disorder (PDD) is associated with high rates of comorbid psychiatric disorders, mostly anxiety disorders (ADs). Comorbid AD was found to be associated with poorer treatment outcome in PDD patients. The effect of comorbid AD on disorder-specific treatment for PDD (Cognitive Behavioral Analysis System of Psychotherapy [CBASP]) has not been studied yet. ⋯ Patients suffering from PDD comorbid with AD might experience greater benefit when they are treated with specific as opposed to unspecific therapy. Analyzing subgroups of patients with PDD seems worthwhile to improve treatment effectiveness even within disorder-specific treatment programms.

Multicenter StudyHPA AXIS RELATED GENES AND RESPONSE TO PSYCHOLOGICAL THERAPIES: GENETICS AND EPIGENETICS.
Hypothalamic-pituitary-adrenal (HPA) axis functioning has been implicated in the development of stress-related psychiatric diagnoses and response to adverse life experiences. This study aimed to investigate the association between genetic and epigenetics in HPA axis and response to cognitive behavior therapy (CBT). ⋯ Allele-specific change in FKBP5 methylation was associated with treatment response. This is the largest study to date investigating the role of HPA axis related genes in response to a psychological therapy. Furthermore, this is the first study to demonstrate that DNA methylation changes may be associated with response to psychological therapies in a genotype-dependent manner.

Randomized Controlled Trial Multicenter StudyTrajectories of change in anxiety severity and impairment during and after treatment with evidence-based treatment for multiple anxiety disorders in primary care.
Coordinated Anxiety Learning and Management (CALM) is a model for delivering evidence-based treatment for anxiety disorders in primary care. Compared to usual care, CALM produced greater improvement in anxiety symptoms. However, mean estimates can obscure heterogeneity in treatment response. This study aimed to identify (1) clusters of participants with similar patterns of change in anxiety severity and impairment (trajectory groups); and (2) characteristics that predict trajectory group membership. ⋯ There is heterogeneity in patient response to anxiety treatment. Adverse circumstances appear to hamper treatment response. To what extent anxiety symptoms improve insufficiently because adverse patient circumstances contribute to suboptimal treatment delivery, suboptimal treatment adherence, or suboptimal treatment response requires further investigation.

Randomized Controlled Trial Multicenter StudyBenefits of child-focused anxiety treatments for parents and family functioning.
To examine (1) changes in parent (global psychological distress, trait anxiety) and family (dysfunction, burden) functioning following 12 weeks of child-focused anxiety treatment, and (2) whether changes in these parent and family factors were associated with child's treatment condition and response. ⋯ Findings suggest that child-focused anxiety treatments, regardless of intervention condition, can result in improvements in nontargeted parent symptoms and family functioning particularly when children respond successfully to the treatment.

Multicenter StudyHedonic tone and its mood and cognitive correlates in Parkinson's disease.
Anhedonia has been mainly reported as a symptom of depression and cognitive impairment in Parkinson's disease (PD) patients. Here, we investigated whether hedonic tone depends on depression and clarified its relationship with the cognitive performance of PD patients with different mood disorders. ⋯ Our findings suggest that anhedonia is related to depression severity and specific cognitive performances in patients with MDD and with no depressive disorder. By contrast, the reduced hedonic tone in patients with MIND is independent from depression severity and cognition. Thus, anhedonia in PD is a heterogeneous and multidimensional phenomenon and require investigation at different levels.
