The Relationship Between the Five-Factor Model of Personality and Symptoms of Clinical Disorders: A Meta-Analysis

This paper describes a meta-analysis of 33 studies that examined the relationship between the Five-Factor Model and symptoms of clinical disorders. The typical pattern found associated with clinical disorders or measures of clinical disorders was high Neuroticism, low Conscientiousness, low Agreeableness, and low Extraversion. Comparisons of diagnostic groups and norm groups showed higher levels of Neuroticism and lower levels of Extraversion than did studies of correlations between measures of the level of a disorder and measures of the five factors. Studies of observer ratings of the five factors showed lower levels of Neuroticism and Openness than did studies of self-report ratings. These and other findings relating to type of scale and type of comparison group have possible clinical implications and raise several questions worthy of further research.     

Connections among symptoms of obsessive-compulsive disorder and posttraumatic stress disorder: a case series

Theoretical, clinical, and empirical implications of the functional connections between symptoms of obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) are abundant. As such, four cases are presented here of men and women who met criteria for comorbid OCD and PTSD. All had been diagnosed with treatment-resistant OCD and were seeking treatment from an OCD specialty clinic or institute, all reported a history of traumatic experiences prior to the onset of OCD, and all appeared to demonstrate negative treatment outcomes. Upon examination, it appeared that symptoms of OCD and PTSD were connected such that decreases in OCD-specific symptoms related to increases in PTSD-specific symptoms, and increases in OCD-specific symptoms related to decreases in PTSD-specific symptoms. Speculations about the function of OCD symptoms in relation to post-traumatic psychopathology are put forth; and theoretical, research, and treatment implications are discussed.     

A review of processing and analysing visual metaphors in psychology

IntroductionA visual metaphor is an image depicting an incongruity in the spatial distribution of visual elements, which is not consistent with reality. In this paper, we present an overview of theoretical and empirical studies on visual metaphor processing.ObjectiveFirstly, attention is given to the spatial distribution of visual elements, which defines the type of visual metaphors as well as the meaning operations required to understand the communicative message. The paper then reviews several empirical studies that collect behavioural measures for assessing visual metaphor processing using questionnaires and exploring the role played by cognitive abilities. In line with the contemporary literature, we then present three semiotic dimensions for visual metaphor processing, namely the expression, conceptualisation, and communication. We then present a pilot study that focusses on these three dimensions. Few research studies have collected behavioural data for visual metaphors processing. This may be due to the lack of theoretical framework in the corresponding field of research. These three semiotic dimensions highlight the value of pursuing research on visual metaphors in the scope of psychology. The presented pilot study could be a starting point for the investigation of visual metaphors in the framework of psychology.ConclusionWe propose future avenues of research that consider the visual structure of metaphors and meaning operations while assessing the influence of cognitive abilities in visual metaphor processing.     

A dimensional analysis of claustrophobia

The present study investigated whether situational and cognitive dimensions of claustrophobia exist. To this end, the Claustrophobia Situations Questionnaire (CSQ) and the Claustrophobia General Cognitions Questionnaire (CGCQ) were developed and exploratory factor analyses were performed on these scales. Two-factor solutions for both the anxiety and the avoidance ratings on the CSQ were obtained, accounting for 40.1% and 34.2% of the variance, respectively. Two subscales were created from the two-factor solution of the anxiety section of the CSQ: (1) Fear of Entrapment and (2) Fear of Physical Confinement. Two subscales were also created from the two-factor solution of the avoidance section of the CSQ: (1) Avoidance of Crowds and (2) Avoidance of Physical Confinement. A three-factor solution was obtained for the CGCQ, accounting for 54.4% of the variance, from which the following three subscales were created: (1) Fear of Loss of Control, (2) Fear of Suffocation, and (3) Fear of Inability to Escape. Cronbach alphas for all subscales ranged from .84 to .94. Exploratory correlational analyses were conducted between the situational and the cognitive dimensions.     

家长对子女人格特点的自由描述──中国儿童样本对“大五”人格结构的验证

运用与荷兰、美国等国的跨文化研究组相同的访谈和编码方法,对我国北京和福州两个城市共４１０位的３至１２岁儿童的家长进行了访谈,目的是从自然语言途径,探讨我国儿童的人格特点,并将结果与国外同样研究进行跨文化比较。结果表明：本样本儿童的人格特点可以运用成人“五因素模型”进行解释。并且,中国家长提供的自由描述完全可以纳入美国和荷兰研究组设计的“１４概念”编码系统。与其他国家的结果相比．中国家长对于“谨慎性”概念的重视程度远高于美国、荷兰和比利时儿童的家长,表现出显著的文化差异。此外,中国家长对于孩子“智力”问题的注意多于西方国家的家长,但对孩子在“宜人性”概念上的描述则最少。     

ASSESSING INFLUENTIAL DIMENSIONS OF REINFORCERS ON CHOICE IN STUDENTS WITH SERIOUS EMOTIONAL DISTURBANCE

We examined how reinforcer rate, quality, delay, and response effort combined to influence the choices of 6 youths with learning and behavior difficulties, and the viability of an assessment methodology derived from matching theory for determining differential responsiveness to those reinforcer and response dimensions. The students were given two concurrent sets of math problems that were equal on two dimensions but competed on two other dimensions (e.g., one set yielded higher rate and lower quality reinforcement than the other). Competing dimensions were counterbalanced across the six conditions of the initial assessment phase, permitting assessment of each dimension on time allocation. The conditions resulting in the most and least time allocated to one problem set alternative relative to the other were then replicated. Time allocated to each of the problems within sets was differentially affected by the reinforcer and/or response dimensions, with allocation patterns varying across students. The results are discussed in the context of implications for the design of treatments and extrapolations from basic research on matching and behavioral economics.     

Mechanics of the animate.

Behavior is treated as basic physics. Dimensions are identified and their transformations from physical specification to axes in behavioral space are suggested. Responses are treated as action patterns arrayed along a continuum of activation energy. Behavior is seen as movement along a trajectory through this behavior space. Incentives or reinforcers are attractors in behavior space, at the centers of basins of lowered potential. Trajectories impinging on such basins may be captured; repeated capture will warp the trajectory toward a geodesic, a process called conditioning. Conditioning is enhanced by contiguity, the proximity between the measured behavior and the incentive at the end of the trajectory, and by contingency, the depth of the trajectory below the average level of the potential energy landscape. Motivation is seen as the potential of an organism for motion under the forces impinging on it. Degree of motivation is characterized by the depth of the potential field, with low motivation corresponding to a flat field and a flat gradient of activation energy. Drives are the forces of incentives propagated through behavior space. Different laws for the attenuation of drive with behavioral distance are discussed, as is the dynamics of action. The basic postulate of behavior mechanics is incentive-tracking in behavior space, the energy for which is provided by decreases in potential. The relation of temporal gradients to response differentiation and temporal discrimination is analyzed. Various two-body problems are sketched to illustrate the application of these ideas to association, choice, scalar timing, self-control, and freedom.     

Delineating generalized anxiety: A preliminary investigation

The present study examined the nature of generalized anxiety, which was defined as the constellation of symptoms listed as diagnostic criteria for generalized anxiety disorder in DSM-III-R. Generalized anxiety was assessed by means of a questionnaire that was especially constructed for this study. Although multidimensional scaling of symptoms reported by a clinically anxious sample produced orthogonal anxiety and panic dimensions, many symptoms were common to both dimensions. Whereas worry was found to be the cardinal feature of generalized anxiety, respiratory symptoms were found to associate closely with panic. These dimensions were replicated in a student sample. It is argued that while generalized anxiety symptoms constitute a unique dimension in the field of anxiety disorders, both panic and generalized anxiety may be linked with a basic anxiety response system. The findings also indicated that worry associated more closely with generalized anxiety than did apprehensive expectations. The heuristic value of the findings are discussed in light of the issue relating to an anxiety-panic continuum.     

The control of responding by auditory stimuli: interactions between different dimensions of the stimuli.

Sounds have position in addition to other dimensions, such as intensity and frequency. Position rapidly gains control of spatially contiguous responses and this may interfere with control of responding by other acoustic dimensions. These experiments investigated interference of a tone-noise discrimination by the discrimination of acoustic position. Squirrel monkeys were studied when responding was differentially reinforced in the presence of both spectral content (tone-noise) and positional differences between the stimuli, and when responding was differentially reinforced only in the presence of spectral differences. Under the first condition, responding rapidly came under the control of the position of the noise in the two monkeys tested. The position of the tone controlled responding in one monkey; in the second monkey, responding came under the control of the spectral content of the tone. Under the second condition, responding was initially under the control of the noise in all three monkeys tested. This persisted for the duration of the condition for two of the monkeys; in one monkey, responding came under the control of the spectral content of the noise. Under the second condition, responding was also initially under the control of the position of the tone for all monkeys, but control by spectral content of the tone relatively rapidly developed in two of three monkeys.     

Long-term efficacy of exercise across diagnostically heterogenous mental disorders and the mediating role of affect regulation skills

BackgroundExercise interventions are efficacious in reducing disorder-specific symptoms in various mental disorders. However, little is known about long-term transdiagnostic efficacy of exercise across heterogenous mental disorders and the potential mechanisms underlying treatment effects.MethodsPhysically inactive outpatients, with depressive disorders, anxiety disorders, insomnia or attention deficit hyperactivity disorder were randomized to a standardized 12-week exercise intervention, combining moderate exercise with behavior change techniques (BCTs) (n = 38), or a passive control group (n = 36). Primary outcome was global symptom severity (Symptom Checklist-90, SCL-90-R) and secondary outcomes were self-reported exercise (Physical Activity, Exercise, and Sport Questionnaire), exercise-specific affect regulation (Physical Activity-related Health Competence Questionnaire) and depression (SCL-90-R) assessed at baseline (T1), post-treatment (T2) and one year after post-treatment (T3). Intention-to-treat analyses were conducted using linear mixed models and structural equations modeling.ResultsFrom T1 to T3, the intervention group significantly improved on global symptom severity (d = −0.43, p = .031), depression among a depressed subsample (d = −0.62, p = .014), exercise (d = 0.45, p = .011) and exercise-specific affect regulation (d = 0.44, p = .028) relative to the control group. The intervention group was more likely to reveal clinically significant changes from T1 to T3 (p = .033). Increases in exercise-specific affect regulation mediated intervention effects on global symptom severity (ß = −0.28, p = .037) and clinically significant changes (ß = −0.24, p = .042).ConclusionsThe exercise intervention showed long-term efficacy among a diagnostically heterogeneous outpatient sample and led to long-lasting exercise behavior change. Long-term increases in exercise-specific affect regulation within exercise interventions seem to be essential for long-lasting symptom reduction.
