New Psychotherapy

Nutrition plays an important role in neurodevelopment. This insight has led to increasing research into the efficacy of nutrition-related interventions for treating neurodevelopmental disorders. This review discusses an elimination diet as a treatment for attention deficit hyperactivity disorder and autism spectrum disorder, with a focus on the efficacy of the food additives exclusion diet, gluten-free/casein-free diet and oligoantigenic diet. Furthermore, we discuss the potential mechanisms of elimination diets' effects in these neurodevelopmental disorders...

Economic, political, and ideological landscapes have impacted the practice of psychiatry throughout its evolution as a medical discipline. Despite enormous scientific advances over the course of the past century, many psychiatrists continue to operate with a split Cartesian picture of mind versus brain and entrenched ideological positions ranging from biological "chemical imbalance" to rigidly followed manualized psychotherapy approaches, both of which frequently result in fractured clinical care...

In the first article in this 2-part series, we outlined a psychobiological model of psychiatric treatment and reviewed the evidence showing psychotherapy to be a form of biological intervention that induces lasting alterations in brain structure and function. In this second article, we focus on the adaptive model of psychopathology, the effectiveness of psychotherapeutic interventions, the synergistic effects of combined psychotherapy and psychopharmacology treatments, and attention to the patient's subjective experience and the doctor-patient alliance to complement an "objective" case formulation...

Recent advances achieved in the field of clinical neuro(bio-)psychology have been varied and impressive. Together with the related social and psychosocial aspects, they contribute to and enrich the development of new options in diagnosis and psychotherapy. Important research results are discussed here based on the examples of depression, Alzheimer's disease and self-injury, which profit greatly from neuropsychological research, especially through early detection of symptoms and prevention.

Item response theory (IRT) measurement models are now commonly used in educational, psychological, and health-outcomes measurement, but their impact in the evaluation of measures of psychiatric constructs remains limited. Herein we present two, somewhat contradictory, theses. The first is that, when skillfully applied, IRT has much to offer psychiatric measurement in terms of scale development, psychometric analysis, and scoring. The second argument, however, is that psychiatric measurement presents some unique challenges to the application of IRT - challenges that may not be easily addressed by application of conventional IRT models and methods...
