Prediction of outcome from cognitive-behavioral treatment of irritable bowel syndrome

The presence of a diagnosable Axis I psychiatric disorder predicted significantly (P < 0.001) lower likelihood of significant improvement among 90 irritable bowel syndrome patients given cognitive and behavioral treatments to help the disorder. Other psychological tests, including the MMPI, BDI, STAI, as well as demographic variables, failed to yield significant prediction.     

Normal and Exceptional Children's Attitudes Toward Themselves and one Another

In this study 65 junior high school boys and girls (54 normal and 11 exceptional children) evaluated themselves most favorably, normal children as a group less favorably, and exceptional children as a group least favorably of all on the Personal Attribute Inventory for Children. This was so regardless of whether the respondents were normal or exceptional children. Since data were collected from mainstreamed classrooms, it appears that mainstreaming may not be directly deleterious to exceptional children's self-concepts, but has associated with it a negative stigma for exceptional children as a group for both exceptional and normal children. These findings, plus others reported previously, fail to demonstrate that mainstreaming in its present form may be an elixir for exceptional children's social-emotional difficulties.     

A Spontaneous Request for Treatment by a Group of Adolescents

In this article, we build on our clinical knowledge in working with the adult children of alcoholics, examining the importance of the “alcoholic” family, past and present, to the current functioning of adults who grew up in such an environment. Specifically, we focus on key issues related to the development of family transference in the group therapy setting.     

Genetic causal beliefs about obesity,self-efficacy for weight control,and obesity-related behaviours in a middle-aged female cohort

Objective: Obesity is a heritable condition with well-established risk-reducing behaviours. Studies have shown that beliefs about the causes of obesity are associated with diet and exercise behaviour. Identifying mechanisms linking causal beliefs and behaviours is important for obesity prevention and control.

Design: Cross-sectional multi-level regression analyses of self-efficacy for weight control as a possible mediator of obesity attributions (diet, physical activity, genetic) and preventive behaviours in 487 non-Hispanic White women from South King County, Washington.

Main Outcome Measures: Self-reported daily fruit and vegetable intake and weekly leisure-time physical activity.

Results: Diet causal beliefs were positively associated with fruit and vegetable intake, with self-efficacy for weight control partially accounting for this association. Self-efficacy for weight control also indirectly linked physical activity attributions and physical activity behaviour. Relationships between genetic causal beliefs, self-efficacy for weight control, and obesity-related behaviours differed by obesity status. Self-efficacy for weight control contributed to negative associations between genetic causal attributions and obesity-related behaviours in non-obese, but not obese, women.

Conclusion: Self-efficacy is an important construct to include in studies of genetic causal beliefs and behavioural self-regulation. Theoretical and longitudinal work is needed to clarify the causal nature of these relationships and other mediating and moderating factors.     

Cognitive therapy for irritable bowel syndrome is associated with reduced limbic activity, GI symptoms, and anxiety

This study sought to identify brain regions that underlie symptom changes in severely affected IBS patients undergoing cognitive therapy (CT). Five healthy controls and 6 Rome II diagnosed IBS patients underwent psychological testing followed by rectal balloon distention while brain neural activity was measured with O-15 water positron emission tomography (PET) before and after a brief regimen of CT. Pre-treatment resting state scans, without distention, were compared to post-treatment scans using statistical parametric mapping (SPM). Neural activity in the parahippocampal gyrus and inferior portion of the right cortex cingulate were reduced in the post-treatment scan, compared to pre-treatment (x, y, z coordinates in MNI standard space were -30, -12, -30, P=0.017; 6, 34, -8, P=0.023, respectively). Blood flow values at these two sites in the controls were intermediate between those in the pre- and post-treatment IBS patients. Limbic activity changes were accompanied by significant improvements in GI symptoms (e.g., pain, bowel dysfunction) and psychological functioning (e.g., anxiety, worry). The left pons (-2, -26, -28, P=0.04) showed decreased neural activity which was correlated with post-treatment anxiety scores. Changes in neural activity of cortical-limbic regions that subserve hypervigilance and emotion regulation may represent biologically oriented change mechanisms that mediate symptom improvement of CT for IBS.
