The effectiveness of adherence intervention in a colon cancer prevention field trial.

BACKGROUND: Adherence interventions were implemented in a 1-year community-based colon cancer prevention clinical trial (n = 110) using wheat bran fiber and calcium dietary supplements. The adherence promotion strategy was guided by a theoretical model. METHODS: The adherence intervention contains both a generalized portion given to all participants and an individualized portion given to marginal (50-74% intake) and low (under 50% intake) adherers. A regression model was employed to assess the effectiveness of the interventions both at the first intervention and at subsequent times. RESULTS: The Health Behavior in Cancer Prevention Model-based adherence promotion intervention was associated with retention of participants, both during the run-in period and after randomization (P = 0.05); and maximization of the percentage of the 13.5-g recommended fiber supplement consumed during the trial (92.5%). The positive effects of the adherence intervention were greater with first-time nonadherers and the control group than with the experimental group. The high-fiber group had notably more biological GI effects from the increased fiber intake, more preexisting comorbidities, and lower perceived cognitive and physical health status. CONCLUSIONS: Randomized participants had excellent adherence overall. Retention rates in the trial were better than would be expected without the adherence intervention, especially among those participants who may have been at higher risk for dropping out of the study. This suggests that a systematic, theoretically based adherence strategy should be further tested in clinical trial settings in which lower adherence is a problem.

Reasons related to adherence in community-based field studies.

This study identified participants' reasons for good, marginal or poor adherence, or withdrawing from community-based clinical studies using a dietary and/or drug intervention. Adults aged 48-75 years participated in one of three studies related to decreasing colon polyp recurrence. Qualitative data from progress notes (N = 675) and end-of-study evaluations (N = 87) were coded using constant comparative analysis with 100% content validity panel agreement. Most common reasons for non-adherence were barriers such as side-effects, interference with vacation plans, unrelated illness, forgetting and competing outside stressors. Participation motivators were benefits such as altruism, medical benefits, free service and staff rapport. Findings supported the Health Behavior in Cancer Prevention model-based approach to adherence interventions and provided directions for adherence promotion in future community-based clinical studies.

Care needs of home-based cancer patients and their caregivers. Quantitative findings.

The purpose of this study was to identify care needs of home-based patients receiving treatment for cancer and their caregivers. The sample consisted of 30 patients receiving radiation therapy and/or immunologically based treatments for a variety of cancers and 29 caregivers. Patient and caregiver needs scales were used to elicit the needs of patients and caregivers. Patients and caregivers were able to cite their unique needs. Patients had more needs for themselves in the areas of personal care, activity management, and interpersonal interaction than did the caregivers. The necessity for individualization of care was noted by both patients and caregivers, an area that nursing is in a unique position to address.

A community-based feasibility study using wheat bran fiber supplementation to lower colon cancer risk.

METHODS: In this feasibility study, free-living older adults (n = 180; means = 67.5 years old) were randomly assigned to one of three levels of a 3-month standardized compliance enhancement program. RESULTS: Regarding subject compliance with the 18 g/day wheat bran fiber supplement, the high compliance enhancement group had a superior regimen compliance rate (88%) versus the medium and low groups, (66 and 29%, respectively) (P = 0.01), with similar attrition rates. CONCLUSION: No significant gastrointestinal side effects and changes in body weight were reported. For similar efficacy, the comprehensive compliance enhancement group had the greatest cost effectiveness.

An exploratory investigation of elders' views on diet, nutrition and cancer prevention.

The goal of this exploratory investigation was to describe views related to diet and cancer prevention among the residents of a southwestern retirement community. Ethnographic interviews were conducted with twelve residents, providing over 500 data bits for this investigation. Several categories representative of the elders' views related to diet and cancer prevention were identified using content analysis. These included Determinants of food choices, Vigilance and diet and Expectations related to diet and cancer prevention. Two cultural themes illustrated the semantic relationships among the categories: "It's not easy to change your diet, especially when you are all alone," and "Eating right helps you resist disease but it is just too late for us." As diet becomes a primary means of reducing one's risk for certain types of cancer, the informed expertise of nutrition educators and health practitioners is needed to assist the public in adopting dietary guidelines. Qualitative data, as presented here, will be useful in developing effective education materials to meet this need.

Perceived home care needs of cancer patients and their caregivers.

The purpose of this study was to identify perceived home care needs of outpatients receiving treatment for cancer and their caregivers. The purposive subsample consisted of 16 subjects, 8 patients receiving treatment as outpatients and their 8 caregivers. Two interview guides, one for the patients and the other for their caregivers, were based on the Neuman Systems Model to assess patient and caregiver stressors The data were analyzed in relation to intrapersonal stressors (within the individual), interpersonal stressors (between the individual and others), and extrapersonal stressors (between the individual and the environment) Several stressors within each category were identified by both the patients and caregivers. Intrapersonal stressors included treatment uncertainty and role change, the interpersonal stressor of lack of social support, and the extrapersonal stressors of lack of transportation and limited finances. In addition, patients identified specific intrapersonal stressors in relation to their situation. These included assistance in coping with physical restrictions resulting in subsequent anger and depression. On the other hand, intrapersonal stressors identified by the caregivers included support in coping with the added responsibilities in relation to patient care, the fear of being alone, guilt, and the interpersonal stressor of limited knowledge regarding the patient situation. The stressors identified by both the patients and caregivers can serve as a beginning means to explore the needs encountered by this population group.

Retaining qualitative validity while gaining quantitative reliability and validity: development of the Transition to Parenthood Concerns Scale.

This article raises issues about the retention of qualitative validity while establishing psychometric estimates of reliability and validity for a scale that was developed from inductively generated concepts to assess and evaluate the learning needs and concerns of expectant parents in the trimester before their baby's birth. A set of practical procedures for pilot testing qualitatively based scales is described. The three procedures, which provide estimates of clarity, apparent internal consistency, and content validity, preserve the assumptions underlying qualitative methods. The ratings from these procedures have provided a base for item and scale revisions and formal quantitative testing.

Innovative retention strategies for nursing staff.

The creation of innovative retention strategies will be a major focus for nursing administration as a shortage of nurses recurs and turnover of staff becomes a problem. A recent study provides information on which to formulate retention strategies. The findings suggest that retention strategies, to be effective, need to be targeted specifically to particular conditions of the nursing staff, e.g., educational preparation and the clinical service on which staff are functioning. The authors outline their research findings and the innovative strategies that have been constructed.

Hospice education about people with AIDS as terminally ill patients: coping with a new epidemic of death.

Hospice care for patients with AIDS often differs from care provided to patients with other terminal illnesses, such as cancer. We designed a seminar series to educate regional hospice staff about these differences and subsequently determined if the educational intervention was associated with improvements in their AIDS-related knowledge, attitudes, or behaviors toward patients with AIDS. Quantitative and qualitative data were collected from seminar participants (n = 63) and a similar comparison group (n = 18) at several time points. Seminar participants significantly improved their AIDS-related behaviors (p.05); and there was a trend toward knowledge improvement. Qualitative data shed light on the quantitative findings. Participants verbalized better understanding of the relatively aggressive care often given to terminally ill patients with AIDS when it enhanced quality of life.
