Smoking relapse during the first year after treatment for early-stage non-small-cell lung cancer.

BACKGROUND: Non-small-cell lung cancer patients who continue to smoke after cancer diagnosis are more likely to experience disease recurrence, decreased treatment efficacy, and treatment complications. Despite this, many continue to smoke, with estimates ranging from 13% to approximately 60%. METHODS: Participants were 154 early-stage, non-small-cell lung cancer patients who had smoked within 3 months before surgery. Patients were followed for 12 months after surgery to assess smoking status and duration of continuous abstinence after surgery. Predictors included medical, smoking history, psychosocial, and demographic characteristics. RESULTS: At some point after surgery, 42.9% of patients smoked; at 12 months after surgery, 36.9% were smoking. Sixty percent of patients who lapsed did so during the first 2 months after surgery. Smoking at follow-up was predicted by shorter quit duration before surgery, more intense Appetitive cravings (expectation of pleasure from smoking), lower income, and having a higher level of education. Time until the first smoking lapse was predicted by shorter quit duration before surgery, more intense Appetitive cravings to smoke, and lower income. Among those who lapsed, greater delay before the lapse was associated with abstinence at the 12-month follow-up assessment. CONCLUSIONS: Nearly half of non-small-cell lung cancer patients return to smoking after surgery if they have recent smoking histories. Most initial lapses happen within 2 months and occur in response to more recent smoking and more intense cravings. Findings suggest that interventions to prevent relapse should target those who wait until cancer surgery to quit smoking and should be started as soon as possible after treatment.

Asthma coaching in the pediatric emergency department.

OBJECTIVES: Coaching and monetary incentives have been used to modify medical behavior of individuals with several chronic diseases, including asthma. The authors performed a randomized, controlled trial of an intervention combining asthma coaching during an emergency department (ED) visit for asthma, and monetary incentive to improve follow-up with primary care providers (PCP). METHODS: Subjects were parents of children 2-12 years of age, with Medicaid or no medical insurance, receiving treatment for asthma in the ED. The primary outcome was a verified PCP visit for asthma within two weeks of the index ED visit. All parents received 15 dollars for their time in the ED. Parents in the intervention group were told that they would receive an additional 15 dollars monetary incentive if a PCP visit was completed. The coach engaged in a dialogue with the parent during the ED visit, and discussed the importance and advantages of seeking follow-up care with the child's PCP. All parents received the usual discharge instructions, including advice to see the PCP within three days. RESULTS: The authors enrolled 92 parents; outcome data were available for 86 (42 controls, 50 intervention). Demographic characteristics were similar in both groups. There was no significant difference in the proportion of patients who had follow-up PCP visits between the intervention (22.0%; 95% confidence interval [95% CI] = 11.5% to 36.0%) and control (23.8%; 95% CI = 12.0% to 39.4%) groups (p = 0.99). CONCLUSIONS: An intervention combining asthma coaching during acute ED visits and a monetary incentive to return for a PCP visit does not appear to increase follow-up with the PCP.

Depressive symptoms after lung cancer surgery: Their relation to coping style and social support.

Lung cancer patients may experience greater emotional distress than patients with other cancers. Studies have shown social support to predict adjustment in other cancers, but findings among lung cancer patients have been equivocal. Coping style has been shown to predict distress among lung cancer patients, but has not been examined in the context of social support. We examined coping style and social support as predictors of depressive symptoms one week after surgery among 119 patients with non-small cell lung cancer. The Beck Depression Inventory was the primary outcome measure. Predictors included age, ECOG performance status, stage of disease, and measures of adaptive coping, less adaptive coping, Directive instrumental social support and Nondirective instrumental social support. Results indicated that 29% of lung cancer patients had scores above a standard cutoff for clinically significant depression. Results also showed that depressive symptoms were directly related to use of less adaptive coping methods and Directive instrumental social support, inversely related to age and use of adaptive coping methods, and unrelated to nondirective social support, stage of disease and performance status. Results extend previous findings by showing that adaptive coping methods are related to severity of distress, and that the benefits of social support may depend on the characteristics of that support.

Ecological approaches to self-management: the case of diabetes.

In the Diabetes Initiative of The Robert Wood Johnson Foundation, an ecological perspective helped identify the following key resources and supports for self-management (RSSM): individualized assessment, collaborative goal setting, skills enhancement, follow-up and support, access to resources, and continuity of quality clinical care. These RSSM reflect the grounding of diabetes self-management in the context of social and environmental influences. Research supports the value of each of these key resources and supports. Differences among self-management interventions may be seen as complementary, rather than conflicting, ways of providing RSSM. This way of understanding differences among interventions may aid development of varied programs to reach diverse audiences. In contrast to the "5 A's" model of key provider services (Assess, Advise, Agree, Assist, and Arrange), RSSM articulate self-management from the perspective of individuals' needs. Both approaches emphasize identification of goals, teaching of skills, and facilitation and reinforcement of the use of those skills.

Refinement of an instrument to evaluate parental attitudes about follow-up care after an acute emergency department visit for asthma.

INTRODUCTION: Prompt follow-up after emergency department (ED) care for asthma allows the primary care provider (PCP) and family to review factors that led to the ED visit, update current care plans, and plan for prevention of future exacerbations. METHODS: The Initial Questionnaire to assess parental impressions of Pros and Cons of follow-up was administered to parents who brought their children to the ED for treatment of an acute asthma exacerbation (N = 309). After a planned interim analysis, 19 new items were generated, and this Expanded Questionnaire was given to 198 parents. Principal Component Analysis (PCA) was used to identify well-defined items and discard ambiguous and confusing items. RESULTS: PCA of the Expanded Questionnaire revealed 18 of 43 items related to four dimensions of parents' Pros and Cons for obtaining follow-up care. Four distinct categories were identified: two Pros and two Cons. Pro items related to practical things parents get from a follow-up visit and to positive parental beliefs about follow-up care. Con items emphasized practical considerations that make it difficult to go to a follow-up visit and identified the misconception that follow-up is not necessary for asymptomatic children. In addition, two distinct clusters of parents were identified: those that value and those that do not value follow-up care. CONCLUSION: We developed an 18-item measure that assesses Pros and Cons of follow-up care for asthma following emergency care, which has four reliable factors: Pro Practical, Pro Attitude, Con Practical, and Con Attitude. This questionnaire may help guide interventions to change perceptions of the need for follow-up. Attention to increasing Pros among those who are reluctant to attend follow-up care may be especially effective.

Differentiated roles of social encouragement and social constraint on physical activity behavior.

BACKGROUND: Social support is, in general, positively associated with exercise behavior. However, social influence may not always be helpful and may sometimes lead to obligation or a sense of intrusion rather than encouragement or assistance. PURPOSE: The objective was to determine relationships among different types of social influence (social encouragement and social constraint) and exercise motivation and exercise behavior. METHOD: Structural equation modeling was used to investigate relationships among exercise and social influence variables. RESULTS: A model was found to fit the data well in which social encouragement had an indirect association with exercise behavior through motivational variables. Social constraint was associated with only one aspect of exercise motivation--"have to", or obligatory, commitment--and had no direct or indirect association with exercise behavior. CONCLUSIONS: These findings emphasize the importance of social influences that promote desirable behaviors in contrast to those that pose constraints on the failure to perform desirable behaviors.

Depression symptoms and antidepressant medicine use in Diabetes Prevention Program participants.

OBJECTIVE: To assess depression markers (symptoms and antidepressant medicine use) in Diabetes Prevention Program (DPP) participants and to determine whether changes in depression markers during the course of the study were associated with treatment arm, weight change, physical activity level, or participant demographic characteristics. RESEARCH DESIGN AND METHODS: DPP participants (n = 3,187) in three treatment arms (intensive lifestyle, metformin, and placebo) completed the Beck Depression Inventory (BDI) and reported on use of antidepressant medicines at randomization and subsequently at each annual visit (average duration in study 3.2 years). RESULTS: On study entry, 10.3% of participants had BDI scores > or =11, which was used as a threshold for mild depression, 5.7% took antidepressant medicines, and 0.9% had both depression markers. During the DPP, the proportion of participants with elevated BDI scores declined (from 10.3% at baseline to 8.4% at year 3), while the proportion taking antidepressant medicines increased (from 5.7% at baseline to 8.7% at year 3), leaving the proportion with either marker unchanged. These time trends were not significantly associated with the DPP treatment arm. Depression markers throughout the study were associated with some participant demographic factors, adjusted for other factors. Men were less likely to have elevated depression scores and less likely to use antidepressant medicine at baseline (9.0% of men and 17.9% of women had at least one marker of depression) and throughout the study (P <0.0001). Those with more education were less likely to have elevated symptom scores (P = 0.0007) but more likely to be taking antidepressant medicine (P = 0.002). Non-Hispanic white participants were less likely than African Americans to have BDI scores > or =11 (P = 0.03), but white participants were more likely to be taking antidepressant medicine than any other racial/ethnic group (P <0.0001). CONCLUSIONS: DPP participation was not associated with changes in levels of depression. Countervailing trends in the proportion of DPP participants with elevated depression symptoms and the proportion taking antidepressant medicine resulted in no significant change in the proportion with either marker. The finding that those taking antidepressant medicine often do not have elevated depression symptoms indicates the value of assessing both markers when estimating overall depression rates.

Improving follow-up for children with asthma after an acute Emergency Department visit.

OBJECTIVE: To improve follow-up with primary care providers after acute Emergency Department (ED) asthma visits for children from low-income urban families. STUDY DESIGN: A prospective, randomized, controlled trial evaluated combined telephone asthma coaching and monetary incentive. The primary outcome was asthma-planning visits with primary care providers within 15 days of index ED visits. The subjects were urban parents whose children were treated for asthma in the ED and had Medicaid or no insurance. RESULTS: We enrolled 527 parents (264 control and 263 intervention). There was a significant difference ( P < .0001) between the intervention (35.7%) and control (18.9%) groups in the proportion of children who had asthma-planning visits and decreased mean nights/days with asthma symptoms by 4.36 intervention and 3.31 control at 2 weeks. The proportions of children with asthma-planning visits and acute asthma care visits during the 16-day to 6-month period were similar for both groups. CONCLUSIONS: Telephone coaching and a monetary incentive significantly increased the proportion of low-income urban parents who brought their children for asthma-planning visits, and decreased asthma symptoms shortly after asthma ED visits. The intervention did not increase subsequent asthma-planning visits or decrease ED visits or hospitalizations.

Smoking urges and relapse among lung cancer patients: findings from a preliminary retrospective study.

BACKGROUND: As part of a prospective study of relapse to smoking among previously resected lung cancer patients, we conducted a retrospective survey to examine factors that may contribute to relapse. METHODS: Patients who had smoked within 3 months before surgery completed measures assessing demographic characteristics, smoking urges, depression, social support, and psychological reactance. RESULTS: Of 43 participants, 19 had relapsed at some point since surgery and 13 were currently smoking. Patients were at relatively low risk of relapse immediately following hospitalization, but at greater risk beginning 2 months later. Younger age and lower educational level predicted current smoking and shorter time to relapse. Craving to smoke was measured as: Appetitive urge (anticipation of pleasure) and Aversive urge (avoidance of negative affect). Both were greater among current smokers. Aversive urge was significantly correlated with depression. Those high on both psychological reactance and Directive social support had heightened Appetitive urges. CONCLUSION: Among lung cancer patients, relapse to smoking may be delayed several months but remains a problem. Appetitive and Aversive motivational pathways and associated urges appear useful in organizing study of the role of psychosocial factors such as depression and social support in relapse to smoking in this group.

Coping and anxiety in women recalled for additional diagnostic procedures following an abnormal screening mammogram.

This study characterized women's concurrent and subsequent levels of emotional distress associated with a questionable mammogram screening and relationships between women's coping and psychosocial adjustment. State anxiety was assessed in 98 women 1 day after receiving a mammogram screening (Time 1), after notification of a questionable screening result that necessitated additional testing (Time 2), and after being informed of their breast-cancer-free status (Time 3). Key findings include (a) women reported a significant increase in anxiety following notification of the need to return for follow-up testing; (b) significant and positive associations were found between anxiety and behavioral approach, behavioral avoidance, cognitive approach, and cognitive avoidance coping in cross-sectional analyses; and (c) cognitive avoidance coping was a strong predictor of final levels of state anxiety in women. Findings suggest that cognitive avoidance coping plays an important role in reducing anxiety in women recalled to clarify an initially ambiguous screening procedure.

Community organization to reduce the need for acute care for asthma among African American children in low-income neighborhoods: the Neighborhood Asthma Coalition.

BACKGROUND: Low-income African Americans exhibit disproportionate prevalences, morbidity rates, and mortality rates for asthma. OBJECTIVE: To determine whether a community-based intervention, the Neighborhood Asthma Coalition (NAC), conducted through a well-established neighborhood organization in St. Louis could improve awareness of asthma, change attitudes about its care, improve asthma management practices, and reduce the need for acute care for asthma. METHODS: The NAC included educational programs for parents and children, promotional activities, and individualized support provided by trained neighborhood residents. African American children, 5 to 14 years of age, with at least 1 incident of acute care (emergency department visit or hospitalization) within the previous year were enrolled from 8 zip code areas with low-income residents and high proportions of Medicaid-eligible children, ie, 4 NAC neighborhoods and 4 comparable control neighborhoods. Evaluations included quarterly telephone interviews to assess asthma attitudes and management and sites of care. Audits of acute care sites covered 12 months before initiation of the NAC through 3 years of the program. RESULTS: A total of 371 patients were contacted and determined to be eligible for the study, and 345 agreed to participate, representing a recruitment rate of 93%. Of those, 15 withdrew and 24 were lost to follow-up monitoring after the initial contact. In addition, 57 were excluded from analysis because of relocation or for other reasons. Utilization data to determine rates of acute care (emergency department visits and hospitalizations) were collected for 249 patients (100 NAC subjects and 149 control subjects). Acute care rates decreased for both the NAC and control groups from the year before intervention to the last year of intervention, with no significant differences between the NAC and control groups. Participation in NAC programming affected the acute care outcome; the NAC-low participation and control groups did not differ but the NAC-high participation group differed significantly from the pooled control and NAC-low participation groups in reductions in acute care rates. Both contacts with NAC staff members and attendance at educational events were associated with changes toward stronger views that asthma can be managed (partial correlation = .27 and partial correlation = .24, respectively). Structural equation modeling demonstrated that participation in the NAC was associated with positive changes on the Index of Asthma Attitudes scale and lower rates of acute care. Social isolation was associated with greater participation in the program and thus reduced care rates. CONCLUSIONS: The NAC reached its intended audience, including those who were socially isolated, brought about changes in management practices, and was associated with promising reductions in acute care rates among active participants in the program.

Hospital readmissions for childhood asthma: a 10-year metropolitan study.

Studies of asthma admissions in the St. Louis metropolitan area have disclosed substantial numbers of children with readmissions. To determine the magnitude of readmissions and attributes of children with readmissions, a retrospective analysis of 8,761 children with 14,905 asthma hospitalizations for January 1, 1990 through December 31, 1999 at the two university affiliated children's hospitals in St. Louis was undertaken. Patient attributes of age, sex, race/ethnicity, residence, payor status, length of stay, and month of admission were compared between patients admitted once during that period and patients admitted multiple times. Main outcome measures were the total number of admissions and time to readmission during the study interval. A Lin, Wei, Yang, and Ying model of time to readmission showed that African-American children with Medicaid or no insurance are at higher risk of readmission (risk ratio 1.28) than are African-American patients with commercial insurance or white/other race/ethnicity patients regardless of insurance. Probability of readmission increased from 30% after a first admission, 46% after a second, and 59% after a third. Prior admission was a more specific indicator of readmission with greater positive predictive value than ethnicity or insurance status or their combination.

Predictors of repeat hospitalizations in children with asthma: the role of psychosocial and socioenvironmental factors.

This study examined relationships between psychosocial factors and asthma rehospitalization patterns in 115 children (ages 4-15) who had > or = 1 hospitalization during the study period. Lifetime history of hospitalizations and new hospitalizations during a 1-year follow-up period were measured, controlling for baseline asthma symptoms and medications. Prospectively, caretaker characteristics (lower sense of mastery, being less emotionally bothered by asthma) predicted greater likelihood of future asthma hospitalizations. Lifetime history of hospitalizations was associated with family impacts (greater family strain and family conflict greater financial strain) as well as caretaker characteristics (greater personal strain, beliefs about not being able to manage one's child's asthma). These findings could help guide future interventions targeted at the subgroup of children who represent a high proportion of asthma hospitalizations.

The Diabetes Prevention Program: recruitment methods and results.

The Diabetes Prevention Program (DPP) is a multicenter randomized controlled trial designed to test whether diet and exercise or medication can prevent or delay the onset of type 2 diabetes in persons with impaired glucose tolerance, who are at increased risk of the disease. This paper describes DPP recruitment methods, strategies, performance, and costs. The DPP developed an organizational structure for comprehensive management and continuous monitoring of recruitment efforts. The DPP utilized a variety of recruitment strategies, alone or in combination, and a stepped informed consent procedure leading to randomization. Studywide and clinic-specific recruitment data were monitored, analyzed, and used to modify recruitment approaches. DPP recruitment was completed slightly ahead of schedule, meeting goals for the proportion of women enrolled and nearly meeting goals for the proportion of racial/ethnic minorities. Clinics varied widely in the recruitment strategies they used, and these strategies also varied by participant age, gender, and race/ethnicity. Staff time devoted to recruitment averaged 86.8 hours per week per clinic, with the majority of effort by staff specifically assigned to recruitment. The number of staff hours required to recruit a participant varied by recruitment strategy. Recruitment cost (excluding staff cost) was about 1075 US dollars per randomized participant. The DPP experience offers lessons for those planning similar efforts: (1) a method for ongoing assessment and revision of recruitment strategies is valuable; (2) a range of recruitment strategies may be useful; (3) the most effective methods for recruiting potential subjects may vary according to the gender, age, and race/ethnicity of those individuals; (4) recruitment strategies vary in the amount of staff time required to randomize a participant; and (5) a stepped screening may make it easier to identify and recruit volunteers who understand the requirements of the study.

Parental impressions of the benefits (pros) and barriers (cons) of follow-up care after an acute emergency department visit for children with asthma.

OBJECTIVE: Asthma morbidity, with increasing emergency department (ED) visits, is prevalent among low-income, urban children. Follow-up care after ED visits is infrequent. We developed and evaluated an instrument that describes the parental benefits (pros) and barriers (cons) of obtaining follow-up care for interventions to promote follow-up. METHODS: We enrolled a convenience sample of low-income, urban parents who brought their children to the ED for treatment of asthma. These parents rated 41 items about the pros and cons of making a follow-up visit. Principal component analysis was used to identify the underlying structure of the instrument. RESULTS: One hundred forty-seven participants were interviewed in the ED. Principal component analysis retained 24 total items, which were identified by this sample as highly associated with deciding to take their child to a follow-up visit. Two types of pros were identified, informational and attitudinal, including "ask the doctor questions," and " children with asthma are healthier if they see their doctor regularly." Two types of cons were identified, practical and attitudinal, including "I have to find transportation," and "I don't need to see the doctor unless my child is sick." The mean total pro and con scores were 4.05 +/- 0.63 and 1.73 +/- 0.67, respectively. CONCLUSIONS: The pros and cons are not unidimensional. Even among those with infrequent follow-up, pros were endorsed more highly than cons. Programs that target these pros and cons may improve adherence to follow-up and regular care for low-income urban children.

Behavioral science research in the prevention of diabetes : status and opportunities.

Recent studies show diabetes can be prevented. Growing knowledge of its biological bases opens further prevention opportunities. This article focuses on behavioral science research that may advance these opportunities. An ecological model guides attention to how prevention research may be pursued at the individual, group, or community levels. Three key areas are reviewed: risk communication, screening, and preventive interventions. Research on diabetes risk communication is limited but suggests that many are relatively unaware of risks and may have misconceptions about the disease. Amid policy debates and research regarding the potential benefits and costs of screening, identification of diabetes may itself be risky in terms of psychological and social consequences. The Diabetes Prevention Program and other studies make clear that diabetes can be prevented, both by the combination of weight loss and physical activity and by medications. Research needs to address promoting these methods to individuals as well as to groups and even whole communities. Fundamental as well as applied research should address how risks of diabetes are understood and may be communicated; how to enhance benefits and minimize psychological and other risks of screening; how to promote healthy eating and weight loss, physical activity, and appropriate use of medications to prevent diabetes; and how to reduce socioeconomic and cultural disparities in all these areas.

Socioeconomic status, stress, and immune markers in adolescents with asthma.

OBJECTIVE: Previous research has demonstrated links between low socioeconomic status (SES) and clinical asthma outcomes, as well as links between stress and asthma. The objective of this study was to test whether adolescents with asthma from different SES backgrounds differed in biological profiles relevant to asthma, including immune and cortisol measures. The second objective was to test whether psychological stress and control beliefs could explain these differences. MATERIALS AND METHODS: Adolescents with persistent asthma from either low (N= 18) or high (N= 12) SES neighborhoods were interviewed about their stress experiences (chronic stress, acute life events, interpretations of ambiguous life events) and control beliefs. Blood was drawn to assess immune (cytokines, eosinophils, IgE) and neuroendocrine (cortisol) markers associated with asthma. RESULTS: Adolescents in the low SES group had significantly higher levels of a stimulated cytokine associated with a Th-2 immune response (IL-5), higher levels of a stimulated cytokine associated with a Th-1 immune response (IFN-gamma), and marginally lower morning cortisol values compared with the high SES group. Low SES adolescents also had greater stress experiences and lower beliefs about control over their health. Statistical mediational analyses revealed that stress and control beliefs partially explained the relationship between SES and IL-5/IFN-gamma. CONCLUSION: Our finding that low SES was associated with elevations in certain immune responses (IL-5/IFN-gamma) in adolescents with asthma suggests the importance of further exploration into relationships between SES and Th-2/Th-1 responses in asthma. Our findings also suggest that psychological stress and control beliefs may provide one explanation for links between SES and immune responses in childhood asthma.
