Placebo, belief, and health. A cognitive–emotion model

The present paper reviews empirical research on placebo effects, and presents a cognitive–emotional model of the psychological mechanisms involved. It is argued that illness often involves psychological aspects; people not only sense their signs of physical illness, but also interpret these signs, and respond emotionally to their interpretations. Cognitions of danger (e.g. fear of dying) produce anxiety, whereas cognitions of loss (e.g. loss of one's health) produce sadness or depression. It is argued that an important part of the placebo effect is due to the development of placebo beliefs (beliefs of the form "This treatment is going to cure me"), which may counteract the kind of cognitions that produce anxiety and depression; placebo beliefs produce emotional responses (hope, calm, etc.), which are antagonistic to depression and anxiety. Further, if anxiety and depression tend to affect a person's physical health negatively, placebo beliefs may be expected to have a positive influence on physical health. Placebo effects may occur not only with pure placebos (e.g. sugar pills), but with all kinds of medical and psychological treatments; even treatments that contain active ingredients of a non-placebo nature may involve important placebo components. Placebo effects may vary in strength, depending on the therapist's behaviour (verbal information to the patient, enthusiasm, optimism, interest, etc.), and on the patient's idiosyncratic meaning structures (which invest various kinds of treatment with different placebo value).     

初中生校园排斥对抑郁的影响：反刍思维与特质正念的作用

研究采用问卷法对955名初中生进行问卷调查,探讨校园排斥对抑郁的影响,以及反刍思维和特质正念的作用。结果表明：（1）校园排斥正向预测初中生抑郁,反刍思维在校园排斥与抑郁间具有中介作用;（2）校园排斥对抑郁的直接效应受到特质正念的调节,直接效应对低特质正念初中生更为显著;（3）特质正念还调节了反刍思维对校园排斥与初中生抑郁中介过程的后半段路径,高特质正念初中生的抑郁水平更低。研究以校园排斥、反刍思维和特质正念为切入点构建了青少年抑郁的影响机制模型,为预防和干预青少年抑郁提供了新的视角和数据支持。      

The cerebrovascular model of depression in late life

Depression in older people, especially depression with an older age of onset, may be a manifestation of acquired brain disease. The cerebrovascular model of depression, often referred to as "vascular depression," hypothesizes that otherwise clinically occult small vessel brain disease contributes to the pathogeneses of some late-life depressive conditions. This paper reviews several lines of evidence supporting the cerebrovascular model and addresses the limitations of the existing literature. Several directions for future research are noted, including empirical testing of the notion that cerebrovascular disease might underlie the pathogeneses of depression with prominent executive dysfunction or other cognitive impairments. At this time, there are no specific therapeutic options for patients with suspected vascular depression beyond standard approaches to depression treatments, although education about the possibly greater risks of chronicity should be included in treatment planning. Therapy of cerebrovascular risk factors and stroke-risk reduction are important as consistent with general practice guidelines, although it is not known whether this will reduce the incidence or improve the outcome of late-life depression.     

The CLASSI-N Method for the Study of Sequential Processes

In many psychological research domains stimulus-response profiles are explained by conjecturing a sequential process in which some variables mediate between stimuli and responses. Charting sequential processes is often a complex task because (1) many possible mediating variables may exist, and (2) interindividual differences may occur in the relationship between these mediating variables and the response. Recently, Ceulemans and Van Mechelen (Psychometrika 73(1):107–124, 2008) addressed these challenges by developing the CLASSI model. A major drawback of CLASSI is that it requires information about the same set of stimuli for all participants (i.e., crossed data), whereas recently a number of data gathering techniques have been proposed in which the set of stimuli differs across participants, yielding nested data. Therefore we present the CLASSI-N model, which extends the CLASSI model to nested data. A simulated annealing algorithm is proposed. The results of a simulation study are discussed as well as an application to data concerning depression.     

Influence of Multiple Traumatic Event Types on Mental Health Outcomes: Does Count Matter?

The experience of potentially traumatizing events (PTEs) may be associated with conflicting outcomes: individuals may experience greater psychological distress (dose-response theory), or individuals may become more resilient against repeated PTEs (stress-inoculation theory). With limited empirical data comparing these theories, we examined the relationships between the count of lifetime PTE types and psychological outcomes [posttraumatic stress disorder (PTSD), depression, impaired distress tolerance] using linear and quadratic regressions. A linear relationship would support the dose-response theory, and a quadratic relationship would support the stress-inoculation theory. We also explored whether there was a threshold number of PTE types fostering resiliency before an increase of distressing outcomes. The sample included 123 (68.30% female) treatment-seeking patients at a community mental health center participating in a larger study (Contractor et al. in Psychiatry Research, 252, 252215–252222, 2017). Linear regression results indicated number of PTE types significantly predicted increasing PTSD and depression severity and distress tolerance difficulties. Quadratic regression model results were not significant. ROC analyses indicated exposure to at least 3.5 PTE types predicted PTSD with moderate accuracy. In conclusion, the dose-response theory was supported, with results indicating there may be a threshold count of lifetime PTE types (> 3) influencing traumatic stress outcomes.     

Simple games as dynamic, coupled systems: randomness and other emergent properties

From a game theory perspective the ability to generate random behaviors is critical. However, psychological studies have consistently found that individuals are poor at behaving randomly. In this paper we investigated the possibility that the randomness mechanism lies not within the individual players but in the interaction between the players. Provided that players are influenced by their opponent’s past behavior, their relationship may constitute a state of reciprocal causation [Cognitive Science 21 (1998) 461], in which each player simultaneously affects and is affected by the other player. The result of this would be a dynamic, coupled system. Using neural networks to represent the individual players in a game of paper, rock, and scissors, a model of this process was developed and shown to be capable of generating chaos-like behaviors as an emergent property. In addition, it was found that by manipulating the control parameters of the model, corresponding to the amount of working memory and the perceived values of different outcomes, that the game could be biased in favor of one player over the other, an outcome not predicted by game theory. Human data was collected and the results show that the model accurately describes human behavior. The results and the model are discussed in light of recent theoretical advances in dynamic systems theory and cognition.     

Chaotic-Enmeshment and Anxiety: The Mediating Role of Psychological Flexibility and Self-Compassion

With anxiety becoming the most prevalent mental health issue among the college student population, it is important to understand the factors that are associated with symptomology. This study aims to expand the research on the interrelationship between family functioning, intrapsychic factors, and anxiety. Guided by the circumplex model of family systems, the current study explores the link between college student (N?=?500) chaotically-enmeshed family functioning and anxiety, and whether psychological flexibility and self-compassion mediate this relationship. Multiple-sample latent structural equation modeling results revealed that higher levels of chaotically-enmeshed family functioning was significantly associated with lower levels of psychological flexibility and self-compassion levels, and that psychological flexibility and self-compassion mediated the relationship between chaotic-enmeshment and anxiety. Implications for family therapists who provide services to this population are discussed.     

Universal Selection Theory: Implications for multidisciplinary approaches to clinical psychology and psychiatry

Universal Selection Theory claims that the increases in the fit of a system to its environment are achieved through a process of blind variation and cumulative selection that is analogous to evolution by natural selection. The process is proposed to occur in many domains, including the gene, behavior, cognition, and culture (meme). This paper reviews the background for the theory and explains how it may contribute to clinical psychology and psychiatry. It is suggested that the theory provides: A framework for integrating biological, psychological and cultural perspectives; an account for why problem-solving and cognitive reappraisal prove to be effective interventions; and an understanding of why psychological disorders can be resistant to change. Implications for psychological treatments, theoretical integration, and future research are discussed.     

大学生的职业自我概念清晰度与抑郁的关系:性别与性别平等观的调节作用

尽管抑郁的影响因素得到了比较多的探讨,但是鲜有研究探讨职业自我概念清晰度与抑郁的关系以及性别和性别平等观在其中的作用。根据生涯发展理论和自我差异理论,本研究探讨了大学生职业自我概念清晰度与大学生抑郁的关系,并考察了性别和性别平等观在二者关系之间的调节作用。通过对463份大学生的数据进行实证分析发现：（1）职业自我概念清晰度与大学生抑郁负相关;（2）职业自我概念清晰度与抑郁的关系存在显著的性别差异;（3）职业自我概念清晰度、性别和性别平等观对大学生抑郁存在三重交互作用。当个体持有高性别平等观时,男性和女性的职业自我概念清晰度都与抑郁负相关。当个体的性别平等观较低时,女性的职业自我概念清晰度与抑郁正相关。研究结果对于大学生的职业发展和心理健康教育具有重要实践意义。     

Behavioral Health Services Influence Medical Treatment Utilization Among Primary Care Patients with Comorbid Substance Use and Depression

Although research has shown benefits of integrating psychological care in primary care settings, it is unclear how this form of treatment impacts individuals with comorbid substance use and depression. The findings are also mixed concerning how frequently this comorbid population seeks primary care services. This study examined the associations between substance use, depression, and medical treatment utilization among 224 primary care patients. The aim of the investigation was twofold. First, to determine if depression increases medical treatment utilization among patients with substance use disorders; second, to evaluate if behavioral health treatment reduces medical service utilization. A moderated mediation model with bootstrapping analyses revealed that depression strengthened the relationship between substance use and primary care treatment utilization (both medical and behavioral health). The model also indicated that behavioral health services were associated with fewer primary care visits for individuals with comorbid substance use and depression. Clinical and social implications are discussed.     

Prolonged Exposure Therapy and Irritable Bowel Syndrome: A Case Study Examining the Impact of a Trauma-Focused Treatment on a Physical Condition

Previous research has shown that psychological treatments, particularly those employing cognitive techniques, are particularly effective in the treatment of irritable bowel syndrome (IBS). It is presumed that these psychological interventions are effective at ameliorating the IBS by treating an underlying psychological disorder (often an anxiety disorder), which may be contributing to the autonomic reactivity. This case study examined the change in the physical symptoms of IBS for a patient seeking treatment for rape-related PTSD with comorbid conditions of major depression and panic. At posttreatment, the patient no longer met criteria for PTSD, major depression, or panic. In addition, her primary symptom of IBS, diarrhea frequency, was significantly improved. These findings were maintained at 3 and 9 months posttreatment. Implications for the assessment and treatment of IBS patients with PTSD are discussed.     

Bridging theory and practice: conceptual understanding of treatments for children with attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), autism, and depression

Serves as an introduction to a special edition of the journal on bridging theory and clinical practice for childhood disorders. Issues concerning the current trend of developing and evaluating new treatments devoid of a theoretical perspective are discussed. A conceptual model of child psychopathology is presented to illustrate the relevance and interplay between theory and the design and evaluation of treatments with particular emphasis on the selection and measurement of target behaviors. The means by which theory and empirical evidence interact and their relevance to understanding particular childhood disorders are discussed and emphasize the need for theoretical and conceptual models that describe the linkages among hypothesized brain substrates, cognitive function, behavior, and the environment to augment the development of potent biological and psychological interventions.     

A PSYCHOBIOLOGICAL REVIEW OF DEPRESSION DURING PREGNANCY

This paper argues that depression may be viewed as one of several normal affective developments of pregnancy rooted in some of the physiological events of gestation and that identification of depression during pregnancy may be difficult (but nonetheless important) because the symptoms of pregnancy and depression are confounded. Studies are reviewed that suggest variations in the incidence and course of depression during pregnancy, some biological bases for such depression when it occurs, some systems through which it might operate, and the possible need for biological and psychological interventions.     

Parental death,depression and beck's theory of cognitive vulnerability: A critical appraisal and suggestions for research

An adequate model of depression should be able to (i) specify the origins of the disorder; (ii) explain the maintenance of depressive behaviour and (iii) result in effective therapy. The adequacy of Beck's cognitive theory of depression has been increasingly questioned (e.g. Alagaratnam, 1984; Alladin, 1985; Bebbington, 1985; Power & Champion (1986); Beidel & Turner (1986); Power (1987) and fundamental questions remain unexplored. In this paper, we focus on the assumption that early parental death results in the development of depressive schemas which constitute a cognitive vulnerability to depression. Bereavement is the most severe psychological trauma most people will encounter in the course of their lives (cf. Parkes & Weiss, 1983). Thus a most stringent test of Beck's hypothesis that depressive schemas are formed in early childhood by loss experiences such as parental death may be conducted by assessing the relationship between adult depression and parental death in childhood. In this paper the evidence will be considered briefly, within the context of Beck's theory of cognitive vulnerability. The specificity of parental loss to depression is questioned. Then, the role of schemas in cognitive theory is explored critically. Problems with Beck's idiosyncratic conceptualisation of depressive schemas are highlighted. A more adequate conceptualisation of the concept of loss is suggested. Finally, suggestions for future research into the origins of depression are offered.     

大学生孤独感对抑郁的影响：基于潜调节的结构方程模型

为探究大学生孤独感、抑郁的关系以及心理僵化和正念在其间的作用,对504名大学生进行调查,并采取基于潜调节的结构方程模型,探讨正念在其中的作用。结果：心理僵化在孤独感和抑郁间起中介作用;正念在孤独感和抑郁间起调节作用。这表明孤独感通过心理僵化影响大学生的抑郁,与低正念水平相比,高正念水平的大学生更不容易受孤独感的消极影响。     

Gratitude and depression in young adults: The mediating role of self-esteem and well-being

This study examined both the mediation effects of self-esteem and psychological well-being for the relationship between gratitude and depression in late adolescence. Two hundred and thirty-five Taiwanese university students completed the measures of gratitude, self-esteem, psychological well-being, and depression. Path analyses indicated that self-esteem and psychological well-being acted as full mediators of the association between gratitude and depression. The identified model also revealed a significant path from gratitude through self-esteem and psychological well-being to depression. A multi-group analysis found that the paths did not differ by genders. Implications for future research and limitations of the present findings are discussed.     

A Brief History of Metacognitive Therapy: From Cognitive Science to Clinical Practice

Metacognitive therapy (MCT) is proving to be an effective treatment for anxiety and depression with effects that may exceed CBT. It has been described as a paradigm shift in psychotherapy in its theory-driven cognitive science approach and systematic development and evaluation. MCT was developed by Adrian Wells based on an information processing theory, the Self-Regulatory Executive Function model by Wells and Matthews. MCT theory formulates psychological disorders as sharing common causal factors under the influence of metacognition, representing a particular top-down model of biases in cognitive regulation. A key clinical implication was that a core set of interventions could be developed to impact a wide range of symptoms and disorders. In this paper, we trace the historical development of MCT and the major studies that informed theory and practice with the aim of introducing clinicians and researchers to this area and to understand why the metacognitive approach has developed into a treatment that is proving to be potentially more effective than current gold-standard treatments. In doing so, we will draw out the distinctive features of the approach and explore how this might offer a blueprint for scientific advancement in clinical psychology and psychotherapy.     

Further explorations in empowerment theory: An empirical analysis of psychological empowerment

Developed empowerment theory and replicated previous research on citizen participation and perceived control. Few investigators have designed studies that specifically test empowerment theory. This research further extends a theoretical model of psychological empowerment that includes intrapersonal, interactional, and behavioral components, by studying a large randomly selected urban and suburban community sample and examining race differences. Results suggest that one underlying dimension that combines different measures of perceived control may be interpreted as the intrapersonal component of psychological empowerment, because it distinguishes groups defined by their level of participation in community organizations and activities (behavioral component). The association found between the intrapersonal and behavioral components is consistent with empowerment theory. Interaction effects between race groups and participation suggest that participation may be more strongly associated with the intrapersonal component of psychological empowerment for African Americans than for white individuals. Implications for empowerment theory and intervention design are discussed. The authors express appreciation to Steven Rosenstone who was the Principal Investigator for the Detroit Area Study from which the data for our study is based. We also thank Deborah A. Salem and the anonymous reviewers for their thoughtful comments on earlier drafts of this paper.
