Validity of the Household and Leisure Time Activities questionnaire (HLTA) in a multiethnic HIV-positive population.

As individuals with HIV/AIDS continue to have longer life expectancies, it is vital that other health outcomes, such as functional status, be considered. The purpose of this study was to explore the psychometric properties of a new functional status measure, the Household and Leisure Time Activities (HLTA) questionnaire, in a multiethnic low-income HIV/AIDS population. The HLTA is an 11-item questionnaire consisting of two scales designed to assess an individual's ability to perform routine home activities (household functioning scale) and to participate in leisure time activities (leisure-time functioning scale). The HLTA was administered, in the form of self-report questionnaires, to 385 consecutive patients seen at a comprehensive HIV/AIDS care facility serving low-income residents of Houston, Texas. Various psychometric procedures were then performed to assess properties, including reliability, construct validity, and concurrent validity. Reliability, assessed by Cronbach's alpha, was good for both scales (0.92, household functioning; and 0.94, leisure-time functioning). Validity was supported by findings from the confirmatory factor analysis and findings from the concurrent validity analyses. Overall, the results indicated that the HLTA has satisfactory psychometric properties and is appropriate for use with multicultural low-income HIV/AIDS patients.

Psychosocial correlates of sun-protective practices of preschool staff toward their students.

The skin cancer rate in the US has been increasing faster than that for other cancers. Most skin cancers are related to sun exposure and the majority of exposure occurs before adulthood. Thus, children are an important target group to study and preschools can be useful avenues for delivering sun-protection messages. The current study examines the behaviors of preschool staff in protecting students from sun exposure and investigates factors related to sun-protective practice. Preschool staff (n = 245) were surveyed about their sun-protective practices toward students as the cross-sectional baseline measurement for a larger project. The primary aim of this study was to investigate correlates of staff's sun-protective behavior toward students. A theoretical model of psychosocial constructs that combined components of the Theory of Planned Behavior and Social Cognitive Theory was evaluated using structural equation modeling. Self-efficacy and perceived norms were the strongest correlates of behavior. A hypothesized link between expectancy and behavior was not supported. The roles of self-efficacy and perceived norms in the preschool context are discussed as they relate to staffs behavior.

Oncology nurses' knowledge, practice, and educational needs regarding cancer genetics.

This study evaluated oncology nurses' knowledge of cancer genetics and related topics, and identified current practice patterns and perceived educational needs in this area. A 54-item study questionnaire was mailed to a random sample of 1,200 Oncology Nursing Society (ONS) members and 75 members of the ONS-Cancer Genetics Special Interest Group; 656 (51%) of those eligible responded. After exclusions, we analyzed 573 responses. Most respondents were Caucasian, female, and worked in hospital or outpatient settings. Half were staff nurses and 8% specialized in cancer genetics. Respondents with higher levels of nursing education or with continuing education in cancer genetics, who worked in positions other than staff nurses, and whose primary practice area was cancer genetics had significantly higher mean scores overall on questions measuring knowledge of cancer genetics and related areas. Higher perceived educational needs to improve knowledge or practice related to cancer genetics at basic, intermediate or advanced levels were associated with all or some of the following variables: lower education; hospital/ outpatient or managed care/private practice settings; lack of continuing education in cancer genetics, and positions other than advanced practice nurses. Although nearly half of the respondents had received patient inquiries regarding cancer genetics, only 35% were aware of referral resources and 26% had made such referrals. These findings may be used to develop targeted educational approaches that prepare oncology nurses to incorporate cancer genetics into any level of practice.

Minority recruitment in the prostate cancer prevention trial.

PURPOSE: African American men have a higher prostate cancer risk profile than that of other men in the United States. The purpose of this manuscript is to summarize the challenges associated with enrolling and randomizing African American and other minority participants in the Prostate Cancer Prevention Trial (PCPT). METHODS: The PCPT is a randomized trial of finasteride versus placebo for preventing prostate cancer in healthy men age 55 years and older; it is coordinated by the Southwest Oncology Group. The manuscript describes demographic and lifestyle characteristics of the PCPT randomized sample (18,882 men) by four racial and ethnic groups (Caucasian, African American, Hispanic, and other). African American men comprised 4% of the total randomized sample compared to our goal of 8%. Minority recruitment was emphasized through the Study Manual and training that occurred at trial activation. Supplemental minority recruitment activities were initiated a year after study activation and continued through the end of the accrual period. Minority recruitment was emphasized as follows: minority recruitment presentations at PCPT training seminars (held during twice yearly Southwest Oncology Group meetings); distribution of additional minority recruitment materials; engagement of four consultants for minority recruitment; production of a Minority Recruitment Manual; and a small pilot study involving minority outreach recruiters at five PCPT sites. RESULTS: The consultants were helpful in implementing the pilot project and in suggesting and reviewing materials for minority recruitment. The five-site pilot project did not increase either enrollment or randomization of minorities (with a possible exception at one site). CONCLUSIONS: We suggest that a long-term perspective is required for successful recruitment of minority participants in clinical trials. Likewise, extensive minority recruitment efforts must be ready to implement at trial activation.

Sun Protection is Fun! A skin cancer prevention program for preschools.

Children and their caregivers are prime candidates for intervention to curb the rising incidence of skin cancer in the United States. Preschools provide a unique opportunity to influence the sun protection practices of parents and teachers on behalf of young children. Sun Protection is Fun!, a comprehensive skin cancer prevention program developed by The University of Texas M. D. Anderson Cancer Center in collaboration with The University of Texas-Houston Health Science Center School of Public Health, was introduced to preschools in the greater Houston area. The program's intervention methods are grounded in Social Cognitive Theory and emphasize symbolic modeling, vicarious learning, enactive mastery experiences, and persuasion. Program components include a curriculum and teacher's guide, videos, newsletters, handbooks, staff development, group meetings designed to encourage schoolwide changes to support the program, and sunscreen. The intervention map, including objectives for program development, implementation, and evaluation, is discussed.

Smoking withdrawal and relapse in head and neck cancer patients.

BACKGROUND: Smoking withdrawal and relapse were characterized among newly diagnosed head and neck cancer patients participating in a physician-delivered smoking cessation intervention. METHODS: Patients completed questionnaires at baseline, 1, 6, and 12 months following intervention delivery. RESULTS: Significant baseline predictors of smoking relapse included medical treatment (XRT versus surgical treatment), stage of change/readiness to quit (precontemplators), age of initiation (younger), and greater addiction (smoking </=30 minutes after waking). Relapsers were significantly more likely to quit using gradual reduction versus cold turkey and had less confidence in remaining quit. Relapsers experienced significantly higher levels of anxiety and craving during withdrawal. Relapse was temporally delayed compared with healthy populations. CONCLUSION: Assistance with cessation efforts should be ongoing for one year and should include nicotine replacement therapy and psychotropic medications to address significant relapse triggers.

Eating orientation, postcessation weight gain, and continued abstinence among female smokers receiving an unsolicited smoking cessation intervention.

Predictors of weight gain following smoking cessation were assessed among 1,219 female smokers enrolled in a health maintenance organization. Women randomized to the treatment group received a cessation intervention without regard to their interest in quitting smoking. It was hypothesized that cessation would result in subsequent weight gain and postcessation weight gain would be associated with scores on a modified Restraint Scale, the Disinhibition Scale, and a scale assessing tendency to eat during periods of negative affect. Persons who abstained from smoking over the 18-month study gained more weight than did intermittent smokers and continuous smokers, and among 762 women who reported at least 1 on-study attempt to quit smoking, 36% gained weight. Weight gain was associated with disinhibited eating and negative affect eating but not with restrained eating. Weight gain also was associated with continued abstinence from smoking.

First year after head and neck cancer: quality of life.

PURPOSE: Treatment regimens for head and neck cancer patients profoundly affect several quality-of-life domains. Rehabilitative needs have been identified through cross-sectional analyses; however, few studies have prospectively assessed quality of life, included assessment of psychosocial variables, and identified predictors of long-term follow-up. PARTICIPANTS AND METHODS: The present study addresses these limitations through a prospective assessment of 105 patients with a newly diagnosed first primary squamous cell carcinoma of the oral cavity, pharynx, or larynx. Participants were enrolled onto a larger randomized controlled trial comparing a provider-delivered smoking cessation intervention with a usual-care-advice control condition. Participants completed a battery of self-report measures after diagnosis and before treatment and additional quality-of-life instruments at 1 and 12 months after initial smoking cessation advice. RESULTS: Participants displayed improvements at 12 months in functional status (P = .006) and in the areas of eating, diet, and speech; however, the latter three represent areas of continued dysfunction, and the changes were not statistically significant. Despite these improvements, patients reported a decline in certain quality-of-life domains, including marital (P = .002) and sexual functioning (P = .017), as well as an increase in alcohol use (P < .001). Predictors of quality of life at 12 months included treatment type, the Vigor subscale of the Profile of Mood States instrument, and quality-of-life scores obtained 1 month after initial smoking cessation advice. CONCLUSION: Results reinforce the need for rehabilitation management through the integration of psychologic and behavioral interventions in medical follow-up.

Intention to learn results of genetic testing for hereditary colon cancer.

INTRODUCTION: This report investigates the correlates of intention to find out genetic test results in colorectal cancer patients undergoing genetic counseling and testing for hereditary nonpolyposis colon cancer. Specifically, we investigated whether intention to learn genetic test results was associated with sociodemographic factors, medical history, psychosocial factors, attitudes, beliefs, and decisional considerations related to genetic testing. MATERIALS AND METHODS: Among 342 colorectal cancer patients who went through an informed consent process and gave blood for genetic testing and who were eligible for a psychosocial questionnaire study, 269 cases completed a baseline interview. Patients were contacted in person during a routine clinic visit or by letter and follow-up telephone call and were interviewed either in person or by telephone. RESULTS: In univariate analysis, intention to learn test results was positively associated with income, quality of life, a belief that being tested will help family members prevent cancer, being worried about carrying an altered gene, and a belief that one has the ability to cope with test results. It was negatively associated with a belief that genetic counseling is too much trouble relative to the benefits. Intention also was positively associated with scales measuring the pros of learning test results and the pros of informing relatives about test results; it was negatively associated with the cons of learning test results. In multivariable analysis, the belief that testing would help family members prevent cancer, being worried about carrying an altered gene, and the pros of learning test results remained statistically associated with intention when other variables were included in the model. CONCLUSIONS: Our findings showed that the positive aspects of genetic testing were more strongly associated with intention than were the negative aspects. They also showed that persons who stated an intention to learn their genetic test results were more likely than persons who did not to affirm both the benefits and the importance of such testing. These results are consistent with the literature on psychosocial aspects of genetic testing for breast cancer.

The Agency for Health Care Policy and Research Smoking Cessation Clinical Practice Guideline. Findings and implications for psychologists.

Smoking is the leading cause of preventable morbidity and mortality in the United States, and the health benefits of quitting smoking are substantial. Nevertheless, over 25% of American adults (48 million individuals) continue to smoke, and the vast majority of quit attempts are unsuccessful. The Agency for Health Care Policy and Research recently addressed the smoking problem by conducting a 2-year research project that was published as the Smoking Cessation Clinical Practice Guideline (Fiore et al., 1996). This article reviews methods, analyses, and results from the Guideline project, and highlights major Guideline recommendations. Guideline findings and recommendations are discussed with respect to their implications for psychology.

Recruitment to a school-based adult smoking-cessation program: do gender and race/ethnicity make a difference?

BACKGROUND: Recruitment to interventional research, clinical trials, and community-based health programs remains a central public health challenge, particularly among low-income and multi-ethnic populations. Utilizing existing community institutions and "opportunistic" communication channels within these settings for recruitment seems an optimal strategy for overcoming barriers to participation. However, such institutions frequently serve heterogeneous populations, and little is known regarding intra-community variations in program uptake. METHODS: This paper reports the gender and race/ethnic differences in subject characteristics and enrollment patterns among 435 Latino and African American participants in a smoking-cessation program delivered through one such community institution, an inner-city school district in Los Angeles County. RESULTS: Enrollees were more likely to be female and Latino. Recruitment strategies tailored specifically to this program were more effective then recruitment through channels such as regular school activities, particularly among African Americans. CONCLUSIONS: Intragroup variations need to be carefully considered in the design and implementation of such programs if they are to receive acceptance and to succeed.

Correlates of psychologic distress in colorectal cancer patients undergoing genetic testing for hereditary colon cancer.

In this article the authors describe the demographic and psychosocial correlates of 2 measures of psychologic distress among 200 colorectal cancer patients undergoing genetic testing for hereditary nonpolyposis colon cancer. The prevalence of symptoms of depression on the Center for Epidemiologic Studies Depression (CES-D) Scale was 24%. In multivariate analysis, female sex, less formal education, fewer sources of social contacts, and less satisfaction with them were associated with high scores on the CES-D Scale. Characteristics associated with high scores on the State-Trait Anxiety Inventory were younger age, less formal education, non-White race, local-regional stage of disease, fewer social contacts, and less satisfaction with them. Information on psychosocial correlates of psychologic distress may prove useful in guiding genetic counseling sessions, in identifying subgroups that need more intensive follow-up, and in developing interventions to facilitate adjustment to genetic test results.

Smoking cessation. 3: Needed healthcare policy changes.

Smoking is the primary preventable cause of mortality and morbidity in our society, killing more than 430,000 people each year--more than 1,000 a day. Despite this deadly record, the treatment of nicotine dependence has not been integrated into routine medical care. Although professionals from many healthcare fields can be effective providers of smoking cessation treatment, relatively few actually advise patients to quit smoking; and even fewer assist their patients in quitting. Systematic changes in healthcare policies are needed to rectify these problems and improve the provision of smoking cessation services. In this article, the issues of who should be providing cessation treatment, why more providers do not offer this service, and what changes should be made to ensure more widespread inclusion of smoking cessation treatment in future healthcare practice are examined.
