Behavior therapy for obesity: Booster sessions and long-term maintenance of weight loss

Following 8 weekly sessions of group behavioral self-control treatment, 75 obese women were assigned to one of five different maintenance conditions: (a) structured behavioral booster sessions held every two weeks; (b) structured behavioral booster sessions held every month; (c) unstructured nonspecific booster sessions held every two weeks; (d) unstructured nonspecific booster sessions held every month; and (e) a control group that received no booster sessions. Follow-ups were conducted at 3, 6, 9 and 12 month intervals. The study was completed in two replications. Results failed to show a significant effect of either booster session content or frequency. All groups continued to lose weight during the first three months of follow-up. Thereafter subjects in Replication 1 showed significant increases in weight over the next 9 months, whereas subjects in Replication 2 maintained their treatment-produced weight loss. The data do not support the view that booster sessions facilitate maintenance.     

Visual images preserve metric spatial information: evidence from studies of image scanning

Four experiments demonstrated that more time is required to scan further distances across visual images, even when the same amount of material falls between the initial focus point and the target. Not only did times systematically increase with distance but subjectively larger images required more time to scan than did subjectively smaller ones. Finally, when subjects were not asked to base all judgments on examination of their images, the distance between an initial focus point and a target did not affect reaction times.     

RELATIONSHIPS BETWEEN EXPERIMENTAL AND CLINICAL PSYCHOLOGY: THE CASE OF BEHAVIOR THERAPY

Behavior therapy is the outstanding example of the beneficial influence of experimental research on clinical practice. Initial applications of laboratory research to clinical disorders consisted primarily of the principles and procedures of operant and classical conditioning. The development and evaluation of the token economy and biofeedback methods are used to illustrate the contribution of operant conditioning, whereas the derivation and efficacy of exposure-based treatments for phobic and obsessive-compulsive disorders exemplify the utility of classical and avoidance conditioning concepts. As behavior therapy has matured and grown more clinically sophisticated, its theoretical and research bases have broadened to include areas such as vicarious learning and self-regulatory processes. Most recently, concepts from modern cognitive and social psychology (e.g., information processing, attribution theory) have begun to guide clinical applications. In turn, different therapeutic approaches have influenced the nature of laboratory research in some areas. Nonetheless, a gap still exists between experimental research and clinical practice. The solution to this perennial problem is not to make scientists of practitioners, but to recognize the unique contributions of basic researchers, clinical investigators, and practitioners, within a consistent framework that specifies the complex interrelationships among the different levels of analysis along the continuum of basic research to clinical practice. Such a framework is sketched-out together with some comments on the reasons for relative paucity of controlled clinical research in the U.S.A. and suggestions for bringing the influence of research findings to bear on practice.     

Selective applications of some extero- and interoceptive biofeedback devices

A number of highly innovative uses for biofeedback devices in mental health care delivery settings are described. These devices are portable and are carried by the client. Exteroceptive or interoceptive sensors are used to automatically deliver feedback about behaviors. The experiments reviewed here demonstrate some of the many treatment possibilities available with remote biofeedback equipment.     

Adult ADHD and/or Sleep Apnea? Differential Diagnostic Considerations with Six Case Studies

An increased interest in the persistence of attention-deficit hyperactivity disorder (ADHD) into adulthood brings concern that adult ADHD may become overdiagnosed. As with ADHD in childhood, various other adult psychological and medical disorders may be associated with ADHD in adulthood, and these related disorders may be mislabeled and mistreated as simple ADHD. One such medical condition is sleep apnea. This paper reviews similarities and differences between ADHD and sleep apnea and presents case histories of six adult patients diagnosed with ADHD who were subsequently found to have at least comorbid obstructive sleep apnea (OSA). Clinicians who diagnose and treat patients with ADHD are advised to become familiar with sleep apnea as a life-threatening condition that presents with overlapping symptoms.     

Order of Presentation and Verbal Recruitment Strategy Effectiveness1

This study examined the relative effectiveness of three different verbal recruitment strategies (opinion conformity, other enhancement, and self-enhancement) presented in different orders. Sixty undergraduates viewed three recruiters, each of whom used a different recruitment strategy to describe a hypothetical graduate program. Participants rated their impressions of each recruiter and then decided which program to attend. Results indicated that presentation order significantly affected participants' ratings of the opinion conforming and self-enhancing recruiters. Furthermore, although participants generally preferred the other enhancing and opinion conforming recruiters, this preference did not translate into a decision to attend the other enhancer's university. Implications for both the recruitment and impression management literatures are discussed.     

An experimental investigation of thought suppression

An experiment investigating the hypothesis that trying to suppress a thought will lead to an immediate and/or delayed increase in its occurrence is reported. Normal subjects listened to a taped story and then verbalized their stream of consciousness during two consecutive time periods. During the first period, one group (suppression) were asked not to think about the tape while two other groups (controls) were asked to think about anything or think about anything including the tape. During the second period, all three groups were instructed to think about anything. Results from the first period failed to support the immediate enhancement hypothesis as the suppression group reported less thoughts about the tape than the controls. However, results from the second period supported the delayed (rebound) hypothesis as subjects who had previously suppressed reported more thoughts about the tape than subjects who had not. The theoretical, methodological, and clinical implications of these results are discussed.     

Sociocultural Influences on Body Image Concerns and Body Change Strategies Among Indigenous and Non-Indigenous Australian Adolescent Girls and Boys

Sociocultural messages about the ideal body build have been studied predominantlyamong White adolescent girls. In the current study we examined the relationships between perceived sociocultural influences, body image concerns, and body change strategies among 47 (22 boys and 25 girls) Indigenous Australian adolescents. These relationships were compared to those from 47 non-Indigenous adolescents (predominantly from an Anglo-Saxon background), who were matched on gender, age, and school grade. Overall, the sociocultural influences were found to be associated with body image concerns and body change strategies among both cultural groups. The only exception was that the sociocultural influences were not associated with the Indigenous girls’ levels of body dissatisfaction or body image importance. These findings are discussed in relation to past studies of White and Black girls.
