A randomized trial of two print interventions to increase colon cancer screening among first-degree relatives.

OBJECTIVE: First-degree relatives (FDRs) of people diagnosed with colorectal cancer (CRC) have a two- to threefold increased risk of developing the same disease. Tailored print interventions based on behavior change theories have demonstrated considerable promise in facilitating health-promoting behaviors. This study compared the impact of two mailed print interventions on CRC screening outcomes among FDRs. METHODS: This randomized trial compared effects of two mailed print interventions--one tailored and one nontailored--on participation in CRC screening among FDRs of CRC survivors. Data collected via phone interviews from 140 FDRs at baseline, 1 week post-intervention, and 3 months post-intervention. RESULTS: At 3 months, both the tailored and nontailored interventions yielded modest but statistically insignificant increases in adherence to any CRC screening test (14% vs. 21%, respectively; p=0.30). While there were no main effects for tailored versus nontailored interventions, there were significant interactions that showed that the tailored print intervention had significantly greater effects on forward stage movement for CRC screening depending on stage of adoption at baseline, race, and objective CRC risk. Receipt of the tailored intervention was 2.5 times more likely to move baseline precontemplators and contemplators forward in stage of adoption for colonoscopy (95% CI: 1.10-5.68) and was three times more likely to move Caucasians forward in stage of adoption for FOBT (95% CI: 1.00-9.07). In addition, the tailored intervention was 7.7 times more likely to move people at average risk forward in stage of adoption for colonoscopy (95% CI: 1.25-47.75). CONCLUSION: The tailored print intervention was more effective at moving Caucasians, those in precontemplation and contemplation at baseline, and those at average risk forward in their stage of adoption for CRC screening. PRACTICE IMPLICATIONS: Both tailored and nontailored print interventions showed moderate effects for increasing CRC screening participation. Tailored print interventions may be more effective for certain subgroups.

Promoting adaptive coping by persons with HIV disease: evaluation of a patient/partner intervention model.

This study evaluated an intervention to facilitate adaptive coping by persons living with HIV (PLWH), with the participation of their cohabiting partners as a dimension of the intervention. An experimental design with randomization was used, and 84 PLWH and their partners were recruited. The intervention was based on a psychosocial educational model that incorporated four 2-hour sessions focused on communication, stress appraisal, adaptive coping strategies, and building social support. Both members of the dyad were included in each session. The comparison control included four supportive phone calls to the PLWH alone. Data were collected from both the PLWH and their partner in each of the two groups at baseline, immediately following the intervention, and 3 months and 6 months posttreatment. Data were analyzed using repeated measures analysis of variance, with change scores from the partner data being covariates. Results indicated that the design was a feasible model, which demonstrated potential for the management of stress and possibly problems such as adherence in PLWH. A manual was developed as a part of this intervention and is currently available.

Impact of the Cancer Risk Intake System on patient-clinician discussions of tamoxifen, genetic counseling, and colonoscopy.

The Cancer Risk Intake System (CRIS), a computerized program that "matches" objective cancer risks to appropriate risk management recommendations, was designed to facilitate patient-clinician discussion. We evaluated CRIS in primary care settings via a single-group, self-report, pretest-posttest design. Participants completed baseline telephone surveys, used CRIS during clinic visits, and completed follow-up surveys 1 to 2 months postvisit. Compared with proportions reporting having had discussions at baseline, significantly greater proportions of participants reported having discussed tamoxifen, genetic counseling, and colonoscopy, as appropriate, after using CRIS. Most (79%) reported CRIS had "caused" their discussion. CRIS is an easily used, disseminable program that showed promising results in primary care settings.

Patients' interest in discussing cancer risk and risk management with primary care physicians.

Little is known about patients' preferences for discussing cancer risks and risk management with primary care physicians. We sought to determine whether patients want to discuss such topics and what factors are associated with this interest. Participants (375 patients ages 40-85, of diverse race and education level) completed a telephone survey prior to scheduled physician visits. Survey included items on perceived health, perceived cancer risk, education level, and whether participants would like to discuss with a physician their breast, ovarian or colon cancer risk, tamoxifen, cancer genetic counseling, and colon cancer screening. Greater proportions were interested in discussing risks for each cancer, compared with those who were not (P < 0.0001). More participants were interested in discussing mammograms (80%) and cancer genetic counseling (60%) than tamoxifen (49%) or colon cancer screening modalities (43-53%). For many topics, poorer perceived health was associated with greater interest in future discussion; higher education level was associated with less interest.

Retention strategies in longitudinal studies with emerging adults.

PURPOSE/OBJECTIVES: The purpose of this report was to describe retention strategies that were useful and those that were not in a longitudinal study of emerging adults. BACKGROUND: A longitudinal study examining the transition to young adulthood among emerging adults with type 1 diabetes, which had success in retention, provided the context for describing retention strategies. RATIONALE: A challenge in longitudinally designed studies is retention of participants because the loss decreases power for statistical analysis. Given that emerging adulthood is a period of instability, retention is particularly challenging among this population. However, longitudinal studies are the best way to understand developmental changes, and it is also important to increase our knowledge of health outcomes during emerging adulthood. DESCRIPTION: Retention strategies used in the study are described, including promoting a positive relationship with participants, maintaining contact with participants, having a study staff with good interpersonal skills, using incentives, conveying respect for participants, and using user-friendly data collection. OUTCOMES: Useful strategies to promote a positive relationship included sending cards and newsletters to participants, maintaining consistency of contact person, and expressing appreciation for participant's time and effort. Useful strategies for maintaining contact with participants included obtaining contact information at every data collection point, maintaining birth dates and chart numbers in tracking databases, monitoring returned mail, and using Web search engines. Other useful strategies were providing incentives to participants, employing staff with good interpersonal skills, providing participants with choices when appropriate, and using user-friendly data collection. One strategy, using contests, was not found useful. CONCLUSIONS: Despite the challenges of conducting longitudinally designed studies with emerging adults, multiple retention strategies can be used that are useful to retention. IMPLICATIONS: It is feasible to conduct longitudinal studies with emerging adults despite the challenges.
