An environmental intervention to restore attention in women with newly diagnosed breast cancer

Bernadine Cimprich; David L. Ronis

Earlier research indicated that attentional fatigue with reduced capacity to direct attention in women treated for breast cancer may be ameliorated by a theoretically based intervention involving regular exposure to the natural environment. This study tested the efficacy of a natural environment intervention aimed at restoring attention in 157 women with newly diagnosed breast cancer. Capacity to direct attention was assessed with a brief battery of objective measures at two time points: approximately 17 days before surgery (time 1) and 19 days after surgery (time 2). A randomly assigned intervention protocol was initiated after the first assessment and before any treatment. The intervention comprised a home-based program involving 120 minutes of exposure to the natural environment per week. The intervention group (n = 83) showed greater recovery of capacity to direct attention from the pretreatment (time 1) to the preadjuvant therapy period (time 2), as compared with the nonintervention group (n = 74). A significant effect of the natural environment intervention was observed even after control was used for the effects of age, education, attention scores at time 1, other health problems, symptom distress, and extent of surgery. The findings suggest therapeutic benefits for capacity to direct attention from early intervention aimed at restoring attention in women with newly diagnosed breast cancer.

Twenty years of cognitive dissonance: Case study of the evolution of a theory

Anthony G. Greenwald; David L. Ronis

Recent revisions of cognitive dissonance theory no longer encompass some of the important examples, data, and hypotheses that were part of Festingers original statement. Further, the psychological character of the motivation for cognitive change can be interpreted, in recent statements of the theory, as a need to preserve self-esteem rather than a need to maintain logic-like consistency among cognitions. These changes are so substantial as to prompt the observation that the evolved theory might be identified as a different theory-in fact, as one that predates cognitive dissonance theory. A final, disturbing thought: What if the original dissonance theory, which has now surrendered its name to somewhat different ideas, was correct?

This pilot study examined the relationship between smoking, alcohol intake, depressive symptoms and quality of life (QoL) in head and neck cancer patients. A questionnaire on smoking, alcohol, depressive symptoms and QoL was distributed to head and neck cancer patients (N=81). Over one-third (35%) of the respondents had smoked within the last 6 months, 46% had drunk alcohol within the last 6 months and 44% screened positive for significant depressive symptoms. About one-third (32%) of smokers were interested in smoking cessation services and 37% of patients with depressive symptoms were interested in depression services. However, only 9% of those who drank alcohol expressed interest in alcohol services. Smoking was negatively associated with five scales of the SF-36V including Physical Functioning, General Health, Vitality, Social Functioning, and Role-Emotional Health. Depressive symptoms were negatively associated with all eight scales on the SF-36V and all four scales of the Head and Neck Quality of Life instrument. Surprisingly, alcohol was not found to be associated with any of the QoL scales. While smoking, alcohol intake and depression may be episodically treated, standardized protocols and aggressive intervention strategies for systematically addressing these highly prevalent disorders are needed in this population.

Changes in Physical Activity Beliefs and Behaviors of Boys and Girls Across the Transition to Junior High School

Anne W. Garcia; R.N. Nola J Pender Ph.D.; Cathy L. Antonakos; David L. Ronis

PURPOSE This longitudinal study investigated gender-specific changes in physical activity beliefs and behaviors across the elementary to junior high school transition. METHODS Physical activity beliefs and behaviors were measured in a cohort of 132 racially diverse youth during the year prior to and following the transition. Questionnaires assessed variables hypothetically linked to activity. Physical activity was monitored with the Child/Adolescent Activity Log. RESULTS Gender differences in physical activity beliefs emerged. Across the transition, boys reported decreased efficacy, social support, and expectations (norms) to be physically active. Although girls also reported decreased social support for physical activity, they further reported exposure to fewer active role models and were less likely to perceive that the benefits of regular activity out-weighed the barriers following the transition. Gender differences in activity levels were apparent, with girls being less active than boys. Despite changes in physical activity beliefs across the school transition, no significant changes in actual level of activity occurred over this period. Although beliefs were significantly related to behaviors in the domain of physical activity, pretransition activity level was the best predictor of posttransition activity level. CONCLUSIONS These data indicate that physical activity beliefs of adolescents change over the school transition. These changes are significantly, but not highly, related to level of physical activity. Future research should explore the influences of activity-related affect and social and physical contexts on physical activity across adolescence.

OBJECTIVE: To estimate prevalence and assess the association of types of trauma with posttraumatic stress disorder (PTSD) in a sociodemographically and racially mixed sample of women from both predominantly Medicaid and privately insured settings who are expecting their first infant. METHODS: Structured telephone diagnostic interview data were analyzed for prevalence of trauma exposure, PTSD, comorbidity, risk behaviors, and treatment-seeking among 1,581 diverse English-speaking nulliparous women. RESULTS: The overall rate of lifetime PTSD was 20.2%, 17% in the predominantly private-payer settings, and 24% in the predominantly public-payer settings. The overall rate of current PTSD was 7.9%, 2.7% in the predominantly private-payer settings and 13.9% in the predominantly public-payer settings. Those with current PTSD were more likely to be African American, pregnant as a teen, living in poverty, with high school education or less, and living in higher-crime areas. Adjusted odds of having current PTSD were highest among those whose worst trauma exposure was abuse (odds ratio 11.9, 95% confidence interval 3.6–39.9), followed by reproductive trauma (odds ratio 6.1, 95% confidence interval 1.5–24.4). Health risk behaviors and exposures were concentrated among those with PTSD. CONCLUSION: These findings affirm that PTSD affects pregnant women. Women with PTSD in pregnancy were more likely to have had exposures to childhood abuse and prior traumatic reproductive event, to have cumulative sociodemographic risk factors, comorbid depression and anxiety, and to have sought mental health treatment in the past. Obstetric risk behaviors occur more in women with PTSD. LEVEL OF EVIDENCE: II

Background: Smoking, alcohol use, and depression are interrelated and highly prevalent in patients with head and neck cancer, adversely affecting quality of life and survival. Smoking, alcohol, and depression share common treatments, such as cognitive behavioral therapy and antidepressants. Consequently, we developed and tested a tailored smoking, alcohol, and depression intervention for patients with head and neck cancer. Methods: Patients with head and neck cancer with at least one of these disorders were recruited from the University of Michigan and three Veterans Affairs medical centers. Subjects were randomized to usual care or nurse-administered intervention consisting of cognitive behavioral therapy and medications. Data collected included smoking, alcohol use, and depressive symptoms at baseline and at 6 months. Results: The mean age was 57 years. Most participants were male (84%) and White (90%). About half (52%) were married, 46% had a high school education or less, and 52% were recruited from Veterans Affairs sites. The sample was fairly evenly distributed across three major head and neck cancer sites and over half (61%) had stage III/IV cancers. Significant differences in 6-month smoking cessation rates were noted with 47% quitting in the intervention compared with 31% in usual care (P < 0.05). Alcohol and depression rates improved in both groups, with no significant differences in 6-month depression and alcohol outcomes. Conclusion: Treating comorbid smoking, problem drinking, and depression may increase smoking cessation rates above that of usual care and may be more practical than treating these disorders separately.

Predictors of sexual intercourse and condom use intentions among Spanish-dominant Latino youth: a test of the planned behavior theory.

Antonia M. Villarruel; John B. Jemmott; Loretta Sweet Jemmott; David L. Ronis

BackgroundSpanish-dominant Latino youth represent a growing yet underserved segment of the U.S. population, especially in terms of protection from sexually transmitted HIV infection. There is evidence to suggest that this subgroup engages in both risk and protective behaviors that may be different from the behaviors of English-dominant Latino youth. ObjectiveTo examine theoretical predictors (attitude, subjective norm, behavioral beliefs, normative beliefs, control beliefs) of sexual intercourse and condom use with a sample of Spanish-dominant Latino youth. MethodsParticipants in this study were part of a larger randomized controlled intervention designed to reduce the risk of sexually transmitted HIV among Latino youth. This article is based on preintervention data from 141 Spanish-speaking Latino adolescents (77 girls and 64 boys) who completed a Spanish version of the questionnaire. ResultsMultiple regression analyses showed significant effects of attitudes, perceived partner approval, self-pride, and parental pride on intentions to engage in sexual intercourse. Attitudes, intentions to engage in sex in the next 3 months, self-pride, parental pride, goals, and partner approval predicted sexual intercourse in the preceding 3 months. Attitudes, subjective norms, self-efficacy, partner and parental approval, and impulse control beliefs were significant predictors of intentions to use condoms. ConclusionsThis study represents initial efforts to address the needs of Spanish-dominant Latino youth. The identification of salient beliefs that may predict sexual risk and protective behavior are relevant to the design of culturally and linguistically effective interventions.

Posttraumatic stress disorder and physical comorbidity among female children and adolescents: Results from service-use data

Objective. In adults, posttraumatic stress disorder (PTSD) is associated with adverse health outcomes and high medical utilization and cost. PTSD is twice as common in women and is associated with increased risk for a range of diseases, chronic conditions, and reproductive-health problems. Little is known about the health effects of PTSD in children. The purpose of this study was to explore patterns of physical comorbidity in female children and adolescents with PTSD by using population data. Methods. This study was a cross-sectional, descriptive epidemiologic case-control analysis of a Midwestern states Medicaid eligibility and paid-claims data for girls (0–8 years old) and teens (9–17 years old). Data were from 1994–1997. All those with the PTSD diagnostic code were compared with randomly selected controls in relation to 3 sets of outcomes: (1) International Classification of Diseases, Ninth Revision (ICD-9) categories of disease; (2) chronic conditions previously associated with sexual trauma and PTSD in women; and (3) reproductive-health problems. Analyses included bivariate odds ratios (OR) and logistic-regression models that control for the extent of insurance coverage and the independent associations of victimization and psychiatric comorbidity with the 3 sets of outcomes. The mental health covariate was categorical to allow consideration of a range of severity. There were 4 categories for the young girls: neither PTSD nor depression, PTSD without depression, depression without PTSD, and PTSD + depression. For the adolescent analysis, a fifth category reflecting a “complex PTSD” was added, defined as having PTSD complicated by a dissociative disorder or borderline personality disorder diagnosis. Results. There were 647 girls and 1025 adolescents with the PTSD diagnosis. Overall, PTSD was associated with adverse health outcomes in both age strata. Victimization was sometimes independently associated with adverse health outcomes, but PTSD often was a mediator, especially in the adolescent age stratum. The importance of PTSD diagnosis as a predictor of the ICD-9 categories of disease or chronic conditions seemed to increase with age. In the younger age stratum, the increased bivariate ORs of significant associations with PTSD ranged from 1.4 for digestive disorders to 3.4 for circulatory disorders. Among younger girls, PTSD diagnosis was associated with significantly greater bivariate odds for 9 of the 12 ICD-9 categories of disease but not for neoplasms, blood disorders, or respiratory disorders and with threefold increased odds for chronic fatigue. They also had 1.8 times greater odds for sexually transmitted infections, some of which could be from congenital transmission in this age group, which includes infants. In the multivariate models for the young girls, the mental health variable seemed to mediate the relationship between victimization and increased odds of infectious and parasitic diseases, endocrine/metabolic/immune disorders, circulatory diseases, skin and cutaneous tissue disorders, and having any 1 of the 5 chronic conditions. The mental health categories that were significantly associated with health outcomes varied across the conditions. There were no health outcomes in which the depression-without-PTSD category was the only one significantly associated with the outcome condition. Circulatory and musculoskeletal disorders were significantly associated with all 3 of the mental health categories. Having any 1 of the 5 chronic conditions was significantly associated only with simple PTSD (PTSD without depression). Genitourinary disorders and signs/symptoms/ill-defined conditions were significantly associated with both simple and comorbid PTSD. PTSD with comorbid depression, the most severe of the mental health categories in this younger age group, was the only category associated with the endocrine/metabolic/immune disorders and skin disorders outcomes. In the adolescent age stratum, the bivariate ORs significantly associated with PTSD ranged from 2.1 for blood disorders to 5.2 for irritable bowel syndrome. Adolescents with PTSD were nearly twice as likely to have a sexually transmitted infection and 60% more likely to have cervical dysplasia. However, their rate of pregnancy was lower (23% vs 31%), a one-fourth decreased odds. In the adolescent group, only 4 outcomes (nervous system/sense organ, digestive, and genitourinary disorders and signs/symptoms/ill-defined conditions) remained statistically significantly associated with victimization after the mental health variable was added, suggesting an additive model of risk for these outcomes but a mediating role for PTSD in relation to the majority of the health outcomes. Among the adolescent girls, the range of ORs for the ICD-9 and chronic-condition diagnoses generally increased across the categories of the mental health variable in a dose-response pattern. Compared with adolescents with neither PTSD nor depression, those with PTSD without depression had statistically significant ORs from 1.5 to 3.6. Those with depression without PTSD had statistically significant ORs from 1.9 to 4.4. The significant ORs for those with PTSD comorbid with depression were from 2.3 to 6.6, and those in the complex-PTSD category had significant ORs of between 2.5 and 14.9. Only blood disorders seemed to be more strongly associated with depression alone than with the comorbid and complex forms of PTSD. The simple-PTSD category was not significantly associated with blood disorders, chronic pelvic pain, fibromyalgia, or dysmenorrhea. Depression without PTSD was not significantly associated with chronic pelvic pain or fibromyalgia. Fibromyalgia was only significantly associated with complex PTSD. Conclusions. In young girls who receive Medicaid benefits, PTSD was associated with increased odds of a range of adverse health conditions. The pattern and odds of physical comorbidity among adolescent recipients with PTSD was nearly as extensive as that seen in adult women. Overall, the pattern observed suggests that objective disease states (eg, circulatory problems, infections) may be associated with PTSD to an extent nearly as great as that of PTSD with more subjective somatic experience of loss of wellness. Using the concepts of allostatic load and allostatic support, professionals who work with children and adolescents may be able to decrease the toll that traumatic stress takes on health even if available interventions can only be thought of as supportive and fall short of completely preventing trauma exposure or completely healing posttraumatic stress. Clinical research to extend these exploratory findings is warranted.

PURPOSE The purpose of this study was to examine whether quality of life (QOL) scores predict survival among patients with head and neck cancer, controlling for demographic, health behavior, and clinical variables. PATIENTS AND METHODS A self-administered questionnaire was given to 495 patients being treated for head and neck cancer while they were waiting to be seen for a clinic appointment. Data collected from the survey included demographics, health behaviors, and QOL as measured by Short Form-36 (SF-36) physical and mental component scores and the Head and Neck QOL scores. Clinical measures were collected by chart abstraction. Kaplan-Meier plots and univariate and multivariate Cox proportional hazards models were used to determine the association between QOL scores and survival time. RESULTS After controlling for age, time since diagnosis, marital status, education, tumor site and stage, comorbidities, and smoking, the SF-36 physical component score and three of the four Head and Neck QOL scales (pain, eating, and speech domains) were associated with survival. Controlling for the same variables, the SF-36 mental component score and the emotional domain of the Head and Neck QOL were not associated with survival. CONCLUSION QOL instruments may be valuable screening tools to identify patients who are at high risk for poor survival. Those with low QOL scores could be followed more closely, with the potential to identify recurrence earlier and perform salvage treatments, thereby possibly improving survival for this group of patients.

Memory dysfunction, psychomotor slowing, and decreased executive function predict mortality in patients with heart failure and low ejection fraction

Susan J. Pressler; JinShil Kim; Penny Riley; David L. Ronis; Irmina Gradus-Pizlo

BACKGROUND The purpose of this study was to evaluate whether dysfunction of specific cognitive abilities is a predictor of impending mortality in adults with systolic heart failure (HF). METHODS A total of 166 stable outpatients with HF completed cognitive function evaluation in language, working memory, memory, visuospatial ability, psychomotor speed, and executive function using a neuropsychological test battery. Demographic and clinical variables, comorbidity, depressive symptoms, and health-related quality of life were also measured. Patients were followed for 12 months to determine all-cause mortality. RESULTS There were 145 survivors and 21 deaths. In logistic regression analyses, significant predictors of mortality were lower left ventricular ejection fraction (LVEF) and poorer scores on measures of global congnitive function Mini-Mental State Examination [MMSE], working memory, memory, psychomotor speed, and executive function. Memory loss was the most predictive cognitive function variable (overall chi(2) = 17.97, df = 2, P < .001; Nagelkerke R(2) = 0.20). Gender was a significant covariate in 2 models, with men more likely to die. Age, comorbidity, depressive symptoms, and health-related quality of life were not significant predictors. In further analyses, significant predictors of mortality were lower systolic blood pressure and poorer global cognitive function, working memory, memory, psychomotor speed, and executive function, with memory being the most predictive. CONCLUSIONS As hypothesized, lower LVEF and memory dysfunction predicted mortality. Poorer global cognitive score as determined by the MMSE, working memory, psychomotor speed, and executive function were also significant predictors. LVEF or systolic blood pressure had similar predictive values. Interventions are urgently needed to prevent and manage memory loss in HF.
