A Protocol Study to Establish Psychological Outcomes From the Use of Wearables for Health and Fitness Monitoring.

The last few decades people have increasingly started to use technological tools for health and activity monitoring, such as tracking apps and wearables. The main assumption is that these tools are effective in reinforcing self-empowerment because they support better-informed lifestyle decision-making. However, experimental research assessing the effectiveness of the technological tools on such psychological outcomes is limited.

Bio-psycho-social interaction: an enactive perspective.

What are the respective roles of physiological, psychological and social processes in the development of psychiatric disorders? The answer is relevant for deciding on interventions, prevention measures, and for our (self)understanding. Reductionist models assume that only physiological processes are in the end causally relevant. The biopsychosocial (BPS) model, by contrast, assumes that psychological and social processes have their own unique characteristics that cannot be captured by physiological processes and which have their own distinct contributions to the development of psychiatric disorders.

Defining Compulsive Behavior.

Compulsive tendencies are a central feature of problematic human behavior and thereby are of great interest to the scientific and clinical community. However, no consensus exists about the precise meaning of 'compulsivity,' creating confusion in the field and hampering comparison across psychiatric disorders. A vague conceptualization makes compulsivity a moving target encompassing a fluctuating variety of behaviors, which is unlikely to improve the new dimension-based psychiatric or psychopathology approach.

Becoming more oneself? Changes in personality following DBS treatment for psychiatric disorders: Experiences of OCD patients and general considerations.

Does DBS change a patient's personality? This is one of the central questions in the debate on the ethics of treatment with Deep Brain Stimulation (DBS). At the moment, however, this important debate is hampered by the fact that there is relatively little data available concerning what patients actually experience following DBS treatment. There are a few qualitative studies with patients with Parkinson's disease and Primary Dystonia and some case reports, but there has been no qualitative study yet with patients suffering from psychiatric disorders.

Effects of Deep Brain Stimulation on the Lived Experience of Obsessive-Compulsive Disorder Patients: In-Depth Interviews with 18 Patients.

Deep Brain Stimulation (DBS) is a relatively new, experimental treatment for patients suffering from treatment-refractory Obsessive Compulsive Disorder (OCD). The effects of treatment are typically assessed with psychopathological scales that measure the amount of symptoms. However, clinical experience indicates that the effects of DBS are not limited to symptoms only: patients for instance report changes in perception, feeling stronger and more confident, and doing things unreflectively.

The phenomenology of deep brain stimulation-induced changes in OCD: an enactive affordance-based model.

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10% of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS).

Social affordances in context: what is it that we are bodily responsive to?

We propose to understand social affordances in the broader context of responsiveness to a field of relevant affordances in general. This perspective clarifies our everyday ability to unreflectively switch between social and other affordances. Moreover, based on our experience with Deep Brain Stimulation for treating obsessive-compulsive disorder (OCD) patients, we suggest that psychiatric disorders may affect skilled intentionality, including responsiveness to social affordances.

On the nature of obsessions and compulsions.

In this chapter, we give an overview of current and historical conceptions of the nature of obsessions and compulsions. We discuss some open questions pertaining to the primacy of the affective, volitional or affective nature of obsessive-compulsive disorder. Furthermore, we add some phenomenological suggestions of our own.

The ghost in the machine: disembodiment in schizophrenia--two case studies.

The notion of embodiment is central to the phenomenological approach to schizophrenia. This paper argues that fundamental concepts for the understanding of schizophrenia have a bodily dimension. We present 2 single cases of first-onset schizophrenic patients and analyze the reports of their experiences.
