Personality disorders and response to outpatient treatment of chronic pain

As part of a comprehensive interdisciplinary evaluation conducted prior to participation in an outpatient chronic pain treatment program, the psychological status of 101 persons was assessed. The majority of participants was found to have a form of personality disorder, determined by conservative cutoff scores applied to their Millon Clinical Multiaxial Inventory (MCMI) profiles. DSM-III-R Cluster C disorders (i.e., Avoidant, Dependent, Obsessive-Compulsive, and Passive-Aggressive) were overrepresented in this sample. Subsequent analyses revealed that personality disorders were related to higher levels of self-reported distress and pain at both the beginning and the end of outpatient treatment. Differential responses to treatment were observed on self-report measures; however, few relations were found between personality disorder and physical therapist ratings of impairment and improvement. Implications for the assessment of personality disorders in outpatient pain treatment programs are discussed and appropriate intervention strategies are considered.     

What makes it a heap?

On the epistemic view of vagueness, a vague expression has sharp boundaries whose location speakers of the language cannot recognize. The paper argues that one of the deepest sources of resistance to the epistemic view is the idea that all truths are cognitively accessible from truths in a language for natural science, conceived as precise, in a sense explained. The implications of the epistemic view for issues about the relations between vague predicates and scientific predicates are investigated.     

Computer program for standardization of curriculum-based probes

This computer program will compute standard scores with any desired mean and standard deviation. The program requires the user to enter the raw scores of each member of the sample to be standardized. The program accepts input from the computer keyboard, stores data in files on a floppy disk, and produces output on the printer.     

Social Comparison and Goal Setting in Brainstorming Groups1

Two studies were conducted to examine the influence of individual and group goal setting on brainstorming performance. Results from the studies indicated that the individual goals of nominal participants were higher than the individual goals of interactive participants. Group goal setting by consensus led to the lowest goals. There was no influence of goal setting on group brainstorming performance. However, participants who set goals rated their individual performance more favorably than did participants who did not set goals. The low group goals set by interactive groups are discussed in terms of assumptions made regarding the ability of other group members and the detrimental effects of group interaction.     

THE DIFFERENTIAL EFFECTS OF TEACHER AND PEER ATTENTION ON THE DISRUPTIVE CLASSROOM BEHAVIOR OF THREE CHILDREN WITH A DIAGNOSIS OF ATTENTION DEFICIT HYPERACTIVITY DISORDER

We conducted functional analyses of classroom disruption during contingent teacher and peer attention conditions for 3 children with attention deficit hyperactivity disorder. Attention provided by peer confederates appeared to function as a distinct form of positive reinforcement for all 3 children.     

Aging of attention: Does the ability to divide decline?

Previous research has yielded conflicting results regarding the relationship between adult age and the ability to divide attention between two concurrent tasks. At least some of the inconsistency is probably attributable to methodological variations, such as the manner in which divided-attention ability has been assessed, how single-task performance has been considered, and the degree of control over relative emphasis placed on each task. Two experiments employing procedures sensitive to these concerns were conducted in which a speeded decision task was performed during the retention interval of a letter-memory task. The results of both experiments indicated that there were relatively few age-related influences on dual-task performance vis-à-vis those on single-task performance.     

The role of target information on manual-aiming bias

Three experiments were conducted to examine the role of target information in manual aiming. The key manipulations in this experiment were the use of two target contexts (the two forms of the Müller-Lyer illusion) and the visual conditions under which subjects moved. In Experiment 1, we demonstrated that the inward- and outward-pointing arrows biased manual-aiming movements in a manner consistent with their well-known influence on perceptual judgements. The elimination of visual feedback during the aiming movement (Experiment 2), and visual information about the target-aiming layout prior to the movement (Experiment 3) increased the magnitude of the bias. Together, these results demonstrate the strong effect of target information on manual aiming, and specifically, on the movement-planning processes that precede movement.     

Co-constructed narratives around being “sick”: A minimalist model

The amount of physical damage may have no fixed relation to how much and in what ways a patient's life is disrupted. The authors discuss a model which addresses the bio-psycho-social complexity of a patient's illness and the narrative constructions which the patient, family members, and health care professionals influence to co-create the patient's identification with being sick. This minimalist model invites the reader to consider a variety of interrelated variable lenses through which to view the narratives around a patient's illness. Clinical case examples are used to illustrate the dominant story themes.
