Sexual and physical abuse are not associated with rectal hypersensitivity in patients with irritable bowel syndrome.

BACKGROUND: Patients with irritable bowel syndrome (IBS) have reduced pain thresholds for rectal distension. In addition, the prevalence of sexual/physical abuse in referred IBS patients is high and is associated with greater pain reporting, poorer health status, and poorer outcome. This lead to a hypothesis that abuse history may sensitise patients to report pain at a lower threshold. AIM: To compare rectal pain thresholds in women with IBS who had a history of severe abuse to IBS women with no history of abuse. METHODS: We studied 74 IBS patients with a history of severe physical and/or sexual abuse and 85 patients with no history of abuse. Abuse history was assessed by a previously validated self-report abuse screening questionnaire. Rectal sensory thresholds were assessed using an electronic barostat and determined by the ascending method of limit (AML) and by the tracking technique. RESULTS: IBS patients with a history of severe abuse had significantly higher rectal pain thresholds, as measured by AML (F (1, 111) = 6.06; p = 0.015) and the tracking technique (F (1, 109) = 5.21; p = 0.024). Patients with a history of severe abuse also reported a significantly higher threshold for urgency to defecate (F (1, 113) = 11.23; p =.001). CONCLUSION: Severe sexual/physical abuse is associated with higher urge and pain thresholds for rectal distension in IBS patients. This suggests that the greater pain reporting and poorer health status in IBS patients with abuse history are not related to increased rectal pain sensitivity. Further studies are needed to determine the causes of these findings.

Self-esteem as a predictor of attitudes toward wife abuse among Muslim women and men in Canada.

This study was designed (a) to assess attitudes toward wife abuse in a sample of Muslim women and men in Canada and (b) to assess whether those attitudes were influenced by self-esteem. Results suggested that, as in general North American samples, the Muslim women and men did not differ from each other on levels of self-esteem. Also consistent with general North American samples, the Muslim women's and men's attitudes toward wife abuse were related to their self-esteem, with higher self-esteem scores predicting stronger attitudes against wife abuse, independent of gender. However, the results also revealed that the Muslim men had significantly more lenient attitudes toward wife abuse compared with the Muslim women and with North American norms.

Concerns of patients with inflammatory bowel disease: results from a clinical population.

OBJECTIVE: The impact of chronic illness is influenced not just by physical symptoms but also by psychosocial factors. The aim of this study was to determine the concerns of inflammatory bowel disease (IBD) patients in a clinical sample, if concerns differ between patients from varied clinical and demographic variables, and if concerns influence well-being beyond the influence of physical symptoms. METHODS: Subjects (n = 259) completed a validated measure of concerns specific to IBD and provided demographic and disease-related information. RESULTS: The most intense concerns involved both physical (e.g., energy level) and psychosocial issues (e.g., achieving full potential). There were numerous differences in disease concerns based on ability to work but none based on disease duration. Factor analysis yielded three indices: body image and interpersonal concerns, general physical impact, and disease stigma. Age and education only affected certain concern indices in subgroups of patients. Greater concerns negatively influenced well-being beyond the influence of physical symptoms. CONCLUSION: Psychosocial factors, in addition to physical symptoms, play an important role on the impact of illness in patients with IBD.

Psychosocial aspects of inflammatory bowel disease.

Crohn's disease (CD) and ulcerative colitis (UC) are known as inflammatory bowel disease (IBD), chronic and potentially disabling diseases, affecting about 90 to 300 per 100,000 people in the general population. Although significant gains have been made in our understanding of these diseases, particularly with respect to pathophysiology and treatment, its etiology is still unknown. IBD is a significant disease that can severely impact one's psychological and social well-being. This article reviews the literature on the psychosocial aspects of IBD. We also address the importance of conceptualizing IBD from a biopsychosocial perspective, considering psychosocial factors along with disease activity. The biopsychosocial approach offers a broadened perspective that reflects the many factors that may contribute to the expression and maintenance of IBD symptoms. Issues of concerns for patients with IBD are also discussed. Finally, we highlight the importance of establishing a collaborative therapeutic relationship between patients and their physicians, facilitating open and honest discussions acknowledging patients' fears and concerns. In doing so, much of these IBD-related issues of concerns may be ameliorated, potentially improving one's coping abilities, and lead to an improved quality of life for individuals with inflammatory bowel disease.

Concerns of patients with inflammatory bowel disease: a review of emerging themes.

Idiopathic, chronic inflammatory bowel disease (IBD) refers to two diseases-ulcerative colitis (UC) and Crohn's disease (CD). Despite an abundant literature discussing the pathophysiology and treatment of these diseases, little if any empirical studies have focused on patients' subjective experiences with their diseases. The purpose of this paper was to identify and discuss the concerns of individuals with IBD and to suggest that the integration of concerns in clinical management is necessary for a comprehensive understanding of these chronic and debilitating diseases. In addition, case studies were included to highlight the concerns of people with IBD. Our review of the literature identified eight categories of concerns for individuals with IBD. They included loss of energy, loss of control, body image, isolation and fear, not reaching full potential, feeling dirty, and lack of information from the medical community. In conclusion, we argue that the efficacy of treatment for IBD would be greatly improved if psychosocial issues were to be integrated into treatment protocols.

Gender role and irritable bowel syndrome: literature review and hypothesis.

Studies examining the prevalence of irritable bowel syndrome (IBS) consistently show that women outnumber men in both patient and nonpatient populations. However, because IBS does affect both women and men, it is important to examine and to understand gender similarities and differences in the expression of this complex disorder. Studies that have explored gender differences have focused their investigations on prevalence and health seeking behavior, physical and psychological symptomotology, and abuse history. This article reviews and summarizes the findings from those studies. As well, whereas the literature examining differences between men and women with IBS has focused on distinctions based on the biological sex of study participants, this article offers an alternate approach to the exploration of gender differences. The concept of gender role, defined as generalizations about appropriate male and female traits that are associated with masculinity and femininity, may further our understanding of IBS in both women and men.

What determines severity among patients with painful functional bowel disorders?

OBJECTIVE: For patients with painful functional bowel disorders (FBD), physicians frequently make diagnostic and treatment decisions based on the severity of the pain reported; patients with severe painful complaints may receive extensive diagnostic tests and treatments. Therefore, it would be important to determine what clinical factors contribute to the judgment of severity among patients with FBD. The aim of this study was to identify the psychosocial, behavioral, and physiological (visceral sensitivity) factors that predicted severity in patients with moderate to severe FBD. METHODS: Two hundred eleven female patients with moderate or severe FBD, as determined by the Functional Bowel Disorder Severity Index, entered a multicenter treatment trial at the University of North Carolina and the University of Toronto. Patients filled out diary cards and were given questionnaires and physiological testing (rectal sensitivity using barostat). Analysis of covariance and logistic regression adjusting for demographic factors were performed to determine which factors distinguished patients at study entry with moderate from those with severe FBD. RESULTS: Patients with severe FBD were characterized by greater depression and psychological distress, poorer physical functioning and health-related quality of life, more maladaptive coping strategies, and greater health care utilization. There was a trend for patients with severe FBD to have lower rectal sensation thresholds. Regression analysis indicated that severity was best predicted by behavioral features: poorer daily physical function, difficulties related to eating, more phone calls to the physician, and more days in bed for GI symptoms. CONCLUSIONS: We conclude that patient illness behaviors are best correlated with severity in FBD. The use of psychopharmacological agents (e.g., antidepressants) and psychological treatments to treat psychiatric comorbidity and to improve behavioral coping styles is recommended. Training to help medical physicians identify and respond to psychosocial and behavioral features of these conditions is likely to improve patient satisfaction with their care and the clinical outcome.

Further validation of the IBS-QOL: a disease-specific quality-of-life questionnaire.

OBJECTIVE: There has been growing interest in the investigation of health-related quality of life (HRQOL) among patients with gastrointestinal (GI) disorders. We recently reported on the development and preliminary validation of the IBS-QOL, a specific quality-of-life measure for irritable bowel syndrome (IBS). The aim of this study was to determine the longitudinal construct validity (responsiveness) of the IBS-QOL. METHODS: Female patients enrolled in a multicenter treatment trial for functional bowel disorders were studied pre- and posttreatment with the IBS-QOL and other health status measures. Based on the response to treatment for several variables (pain/14-day score, daily function, and days in bed/3 months), patients were stratified into Responders, Partial Responders, and Nonresponders. Change scores in the IBS-QOL were then statistically compared with changes in the other variables to determine their correlation and whether Responders were significantly different from non- and Partial Responders on the IBS-QOL. RESULTS: There was a significant correlation between change scores on the IBS-QOL and the other measures of treatment effect (Pain/14 days, r = 0.25, p < 0.002; Sickness Impact Profile [SIP] Total Score, r = 0.28, p < 0.0004). In addition, the IBS-QOL scores significantly differentiated Responders from Nonresponders for most of the variables tested (regression trend test for Pain/14 days, p < 0.04; SIP Total, p < 0.0001; SIP Physical, p < 0.0001; SIP Psychosocial, p < 0.002, and SIP Eating, p < 0.04). CONCLUSION: The IBS-QOL is responsive to treatment in a referral-based clinical population of patients with functional bowel disorders.

The effects of the ideal of female beauty on mood and body satisfaction.

OBJECTIVE: The present study examined changes in women's mood states resulting from their viewing pictures in fashion magazines of models who represent a thin ideal. METHOD: Female university students completed the Profile of Mood States (POMS), the Body Parts Satisfaction Scale (BPSS), and the Eating Disorder Inventory (EDI). They were then exposed to 20 slides; the experimental group (N = 51) viewed images of female fashion models and a control group (N = 67) viewed slides containing no human figures. All subjects then completed the POMS and the BPSS again. RESULTS: Women were more depressed (R2 = 0.745, p < .05) and more angry (R2 = 0.73, p < .01) following exposure to slides of female fashion models. DISCUSSION: Viewing images of female fashion models had an immediate negative effect on women's mood. This study, therefore, supports the hypothesis that media images do play a role in disordered eating.

Psychosocial aspects of the functional gastrointestinal disorders.

The functional gastrointestinal disorders (FGID) are the most frequent conditions seen in gastroenterology practice and comprise a major portion of primary care. Psychosocial factors are important in these disorders with regard to: (1) their effects on gut physiology; (2) their modulation of the symptom experience; (3) their influence on illness behavior; (4) their impact on outcome; and (5) the choice of the therapeutic approach. This paper provides a review and consensus of the existing literature by gastroenterologists, psychiatrists, psychologists, physiologists, and health services investigators. Evidence is provided to support the biopsychosocial model as a basis for understanding and treating these disorders, and epidemiological and clinical information on the relations of psychosocial factors to gut physiology, symptom presentation, health behavior, and outcome is offered. Features of motility, personality, abuse history, health concerns, and treatment-seeking differ between patients with FGID and healthy controls, but they are not specific to FGID. They occur in other patients with chronic medical conditions and/or psychiatric disorders. Review of treatment trials indicates clear support for psychotherapeutic treatments, especially in the long term, as well as some evidence for the benefit of antidepressants in FGID, even in the absence of improvements in mood.

Features of eating disorders in patients with irritable bowel syndrome.

The relationship between characteristics of irritable bowel syndrome (IBS) and eating disorders (ED) was investigated in a clinical sample of 43 female and 17 male IBS patients who completed the Eating Disorder Inventory (EDI). A diagnosis of IBS was generally unrelated to the Body Dissatisfaction, Perfectionism, and Ineffectiveness subscales of the EDI, but symptom severity was correlated with Perfectionism and Ineffectiveness. Severe bouts of vomiting were significantly associated with desires for lower body weight and reported binge-purge behaviors and cognitions measured by the Bulimia subscale of the EDI. Results suggest the need for a more comprehensive understanding of both types of illness as well as a possible framework for future empirical work.

Cognitive-behavioral group therapy for patients with irritable bowel syndrome.

This article is divided into two parts, the first of which focuses on a general overview of irritable bowel syndrome (IBS) and provides a rationale for the use of cognitive-behavioral therapy (CBT) for IBS based on both theoretical and research perspectives. This section includes a critical review of CBT therapies for IBS and provides a model of CBT for IBS. The second section provides the clinician with practical information concerning the application of cognitive-behavioral group therapy for IBS. Possible scripts and case examples are incorporated into this section to highlight factors that may arise in working with IBS patients relative to other clinical groups. The second section also contains themes that are suggested content areas for group sessions. Contingent on the formulation of the presenting or emerging issues and goals, the order and inclusion of themes can be changed to fit the particular needs of a given group. Finally, this section provides initial preliminary data from a randomized controlled study that is suggestive of the efficacy of cognitive-behavioral therapy for IBS.

Sex-role attitudes and clinical appraisal in psychiatry residents.

OBJECTIVE: To measure sex-role beliefs of psychiatry residents and to examine bias in clinical appraisal. METHOD: Residents (45 female, 51 male) evaluated 1 of 4 possible clinical case histories-a female or male patient with histrionic personality disorder (HPD) or antisocial personality disorder (APD)-and completed the Sex-Role Egalitarianism Scale (SRES). RESULTS: As predicted, female residents were more egalitarian than male residents (P < 0.03) according to the SRES. As expected, significantly more male than female patients received the diagnosis of APD (P < 0.00002). Although it was predicted that female patients would more often be given the HPD diagnosis than males, no significant gender differences were found. Sex of resident was not found to influence clinical behaviour significantly. CONCLUSIONS: These results highlight differential sex-role attitudes, as measured by the SRES, between female and male residents and suggest that residents' sex-role biases affect the diagnosis of APD. These results have implications for psychiatric assessment and treatment. Further understanding of these issues is critical to the development of educational tools to address sex biases in psychiatry.

Functional bowel disorders. A multicenter comparison of health status and development of illness severity index.

In a multicenter study of patients with painful functional bowel disorders (FBD), we compared the demographic, health status, and diagnostic features of patients with FBD and developed a functional bowel disorder severity index (FBDSI) for research and clinical care. Two hundred seventy patients with FBD in the United States, England, and Canada were surveyed on symptoms and health status, and their physicians made a diagnosis and rated illness severity as mild, moderate, or severe. Comparisons of 22 demographic and clinical variables were made by study site in addition to physicians' severity ratings. To develop the FBDSI, multiple regression analysis used the demographic and clinical variables to predict the physician's rating of severity. We found that most health status measures of patients with FBD across study sites are comparable and the derived and validated FBDSI scoring system uses three easy to obtain variables: FBDSI = [current pain by visual analog scale (0-100)] + [diagnosis of chronic functional abdominal pain (0 if absent and 106 if present)] + [number of physicians visits over previous six months x 11]. The FBDSI can be used to select patients for research protocols and/or follow their clinical outcome or response to treatments over time.

Substance use disorders in a sample of Canadian patients with chronic mental illness.

In a study designed to investigate the pattern of substance use disorders among a group of chronic mentally ill patients in Toronto, 102 patients completed the Structured Clinical Interview for DSM-III-R and a modified substance-use-disorder module of the Diagnostic Interview Schedule. Forty percent of the sample met criteria for substance use disorders, and 49 percent for personality disorder. Among patients with personality disorder, all those with a personality disorder in cluster B (that is, with antisocial, borderline, histrionic, or narcissistic personality disorder) had a substance use disorder, while the majority of patients in cluster A and cluster C were not substance abusers. In the overall sample, the group with substance use disorders was significantly younger than the group without. In contrast to findings of previous studies, women met criteria for substance use disorders as often as men did.

Social desirability and irritable bowel syndrome.

The Marlowe-Crowne Social Desirability Scale, a 33-item self-report questionnaire, was administered to an age-matched sample of twenty-five irritable bowel syndrome (IBS) patients, twenty-four psychiatric patients meeting a diagnosis of major depression, and nineteen controls. As predicted, planned comparisons analysis showed a significant group effect: IBS group scores were significantly higher than both depressed and control group scores (p less than .05). Implications of this social desirability response set for the psychological assessment and treatment of IBS are discussed.

Thought disorder and verbal recall in acutely psychotic patients.

This study examined the relationship between thought disorder and verbal recall in schizophrenic, manic, and schizoaffective inpatients. Based on previous research, it was predicted that subjects who demonstrated only positive thought-disorder would differ from those with positive and negative thought-disorder in terms of their ability to encode short descriptive passages. Unlike controls, who were able to encode organized material better than unorganized material, neither thought-disorder group improved its encoding when the material to be remembered was more organized. Both thought-disorder groups remembered more when the material was less organized. These findings raise a number of issues with regard to the interrelationship among thought disorders, psychiatric diagnoses, and information-processing deficits.

Pattern of substance abuse in psychiatric inpatients.

This study examined the pattern of substance abuse in a sample of 114 psychiatric inpatients using a standardized diagnostic interview. As predicted, psychiatric inpatients reported a significantly higher rate of substance abuse than a randomly selected community sample. Approximately three-quarters of the inpatients abused at least one substance. Almost one-half of the patient sample reported abusing more than one substance. These findings emphasize the need to screen psychiatric inpatients for substance abuse using a standardized diagnostic instrument and to develop treatment programs for substance abuse in psychiatric patients.
