Experimental psychopathology, clinical science, and practice: An irrelevant or indispensable alliance?

Psychopathology research is the scientific foundation for legitimate and credible forms of clinical practice and the ethical delivery of mental health services. Experimental psychopathology is a subfield of psychopathology research; its aims are to elucidate variables and processes that contribute, either in whole or in part, to the etiology, exacerbation, or maintenance of abnormal behavior. To date, experimental psychopathology has been poorly understood with regard to its identity, aims, history, and relevance for clinical practice. In this article, we critically review and address the role of experimental psychopathology in the contemporary field of clinical science and practice. Overall, we suggest that experimental psychopathology can maintain its important contributions to the field, and perhaps more important, adapt to the current health care context to have an even larger impact on directing conceptual and empirical analyses of core psychopathology processes.     

Teaching Clinical Psychology Trainees about Weight Bias

Abstract

As an assistant professor who teaches clinical psychology trainees about social aspects of behavior, I devote one week to the topic of weight bias. In this class, I rely on the research literature to challenge common myths about “obesity,” demonstrate the pervasiveness and harm of weight bias, and offer recommendations to trainees to apply to their own professional and personal lives. I encourage trainees to shift focus from weight and weight loss to health and well-being and to engage in self-reflection on the role of weight bias in their interactions with others. Here, I describe my weight bias seminar and outline common questions and my responses to them (e.g., Do you actually believe that “obese” people can be healthy?). Weight bias is a neglected topic in most clinical psychology training programs. Weight bias must be addressed in clinical psychology programs to produce culturally competent graduates who are aware of diversity issues.

How structured and unstructured sport activities aid the development of expertise in volleyball players

This study sought to analyse self-reported perceptions of how the nature of sport activities undertaken by volleyball players aided their development. Thirty highly skilled and thirty less skilled players participated in retrospective interviews to identify the nature of activities undertaken in their developmental pathways. All players reported having an early-diversified sport involvement with participation in both structured and unstructured activities. Highly skilled players differed from less skilled players by having accumulated more hours of structured sport activities, some of which were undertaken with older peers. Furthermore, highly skilled players specifically highlighted the value of their involvement in particular unstructured activities with older peers and recognized their importance for expertise achievement. These findings illustrate the importance of considering the role of unstructured (in addition to structured) sport activities in the development of expertise in volleyball. Further work is needed to verify the generality of the findings to other sports.     

Four Faces of Fair Subject Selection

Abstract

Although the principle of fair subject selection is a widely recognized requirement of ethical clinical research, it often yields conflicting imperatives, thus raising major ethical dilemmas regarding participant selection. In this paper, we diagnose the source of this problem, arguing that the principle of fair subject selection is best understood as a bundle of four distinct sub-principles, each with normative force and each yielding distinct imperatives: (1) fair inclusion; (2) fair burden sharing; (3) fair opportunity; and (4) fair distribution of third-party risks. We first map out these distinct sub-principles, and then identify the ways in which they yield conflicting imperatives for the design of inclusion and exclusion criteria, and the recruitment of participants. We then offer guidance for how decision makers should navigate these conflicting imperatives to ensure that participants are selected fairly.     

Verbal and practical intelligence in general anxiety,obsessive compulsive and major depression disorders

IntroductionPrevious researches have shown that anxiety symptoms are negatively associated with measures of intelligence. However, recent findings indicate possible positive relationships between Generalized Anxiety Disorders (GAD) and intelligence. Also, Obsessive Compulsive Disorder (OCD) is associated with a moderate degree of underperformance on cognitive tests, including deficient processing. There are inconsistent results to present the relationship between Major Depression Disorder (MDD) and IQ. The present study has three main aims. The first aim of this study is to investigate the difference between IQ in individuals with GAD, OCD and major depressive disorder, and normal group. The second purpose is to perform a comparative study between the GAD, OCD and MDD groups on verbal and non-verbal intelligence. The third aim of this study is to examine the relationships between GAD, OCD and MDD as well as their underlying cognitive processes, including worry, rumination, and post-event processing, with verbal and non-verbal intelligence.ObjectiveThe present study is performed on four groups of participants including those with GAD, OCD, MDD and Healthy Volunteer (HV) group consisting of individuals without psychiatric disorders.MethodThe number of 50 healthy volunteers as the control group, 45 patients with GAD, 20 patients with OCD and 25 patients with MDD (n = 140) were selected as the case-referent groups. The present study was a cross-sectional type and the research was performed based on the causal-comparative method. Verbal and non-verbal intelligence was measured with the Wechsler Adult Intelligence Scale-3rd edition (WAIS-III). Rumination and post-event processing were measured by PSWQ, RRS-BR, and PEPQ, respectively.ResultsThe results indicate that Verbal Intelligence and Verbal Comprehension Index in GAD patients have significant differences in comparison to the OCD, MDD and control groups. While, the value of the Working Memory Index (WMI) in the normal group is higher than the value of the same index in the GAD, OCD and MDD groups. Also, the values of the Processing Speed Index (PSI) in normal and GAD groups are higher than the OCD and MDD groups. The worry, rumination, and post-event processing in patients with GAD are positively correlated with general and verbal intelligence. But, verbal and non-verbal intelligence had a negative correlation with worry, rumination and post-event processing in healthy volunteers.ConclusionInvestigation of the possible connections between intelligence and the cognitive processes underlying emotional disorders can provide therapeutic strategies for smart individuals who are at risk for GAD.
