Background: To date no research has investigated the link between Post Traumatic Stress Disorder (PTSD) and perfectionism in a clinical sample. Aims: The aim of the current study was to examine whether there is a relationship between PTSD and perfectionism. This is important to address as many studies have demonstrated a link between other anxiety disorders, eating disorders, depression and perfectionism. The research also aimed to examine whether rumination was a mediator of the relationship between PTSD and perfectionism. Method: The sample consisted of 30 participants who were currently in treatment for PTSD. Results: The results suggest that perfectionism and PTSD symptoms were significantly correlated. In addition, rumination was a significant mediator of the relationship between Concern over Mistakes and PTSD. Conclusions: These findings help increase understanding about the relationships of perfectionism and rumination in PTSD and have implications for the treatment of PTSD.

Abstract Background: Previous research from the fields of computer science and engineering highlight the importance of an iterative design process (IDP) to create more creative and effective solutions. Objective: This study describes IDP as a new method for developing health behavior interventions and evaluates the effectiveness of a dining hall-based intervention developed using IDP on college students’ eating behavior and values. Participants: participants were 458 students (52.6% female, age = 19.6 ± 1.5 years [M ± SD]). Methods: The intervention was developed via an IDP parallel process. A cluster-randomized controlled study compared differences in eating behavior among students in 4 university dining halls (2 intervention, 2 control). Results: The final intervention was a multicomponent, point-of-selection marketing campaign. Students in the intervention dining halls consumed significantly less junk food and high-fat meat and increased their perceived importance of eating a healthful diet relative to the control group. Conclusion: IDP may be valuable for the development of behavior change interventions.

5-Hydroxytryptamine 2A receptor antagonists as potential treatment for psychiatric disorders.

Introduction: 5-Hydroxytryptamine 2A receptors (5-HT2A-Rs) are widely expressed in the brain and have been implicated in mood and behavior. Based on the use of atypical antipsychotics in schizophrenia, antagonism of 5-HT2A-Rs initially emerged as a potential intervention capable of reducing the incidence of extrapyramidal symptoms, while exerting an effective antipsychotic action. More recently, highly selective 5-HT2A-R antagonists have been evaluated in the treatment of a wide range of other psychiatric disorders. Areas covered: The aim of the current review is to present important clinical studies investigating the potential therapeutic effects of 5-HT2A-R antagonists in both primary psychiatric disorders, such as schizophrenia and mood disorders, as well as in psychiatric manifestations of neurodegenerative disorders. We present an overview of 5-HT2A-Rs in normal brain function and the rationale for use in (neuro) psychiatric disease based on significant findings from genetic association studies, neuroimaging data and postmortem studies. The majority of the studies relate to schizophrenia, depression, anxiety, obsessive compulsive disorder and psychosis in Parkinson’s disease and Alzheimer’s disease. To date, there is sparse literature on 5-HT2A-Rs in Gilles de la Tourette syndrome, attention deficit hyperactivity disorder, eating disorders and autism spectrum disorders. The authors conclude by reviewing recent clinical trials investigating highly selective 5-HT2A-R antagonists in schizophrenia, psychosis in Parkinson’s disease, insomnia and generalized anxiety. Expert opinion: Despite the potential, to date, 5-HT2A-R antagonists have not made an impact in the management of psychiatric disorders and psychiatric symptoms of neurodegenerative conditions.
