Modeling the effects of spirituality/religion on patients' perceptions of living with HIV/AIDS.

BACKGROUND: Spirituality/religion is an important factor in health and illness, but more work is needed to determine its link to quality of life in patients with HIV/AIDS. OBJECTIVE: To estimate the direct and indirect effects of spirituality/religion on patients' perceptions of living with HIV/AIDS. DESIGN: In 2002 and 2003, as part of a multicenter longitudinal study of patients with HIV/AIDS, we collected extensive demographic, clinical, and behavioral data from chart review and patient interviews. We used logistic regression and path analysis combining logistic and ordinary least squares regression. SUBJECTS: Four hundred and fifty outpatients with HIV/AIDS from 4 sites in 3 cities. MEASURES: The dependent variable was whether patients felt that life had improved since being diagnosed with HIV/AIDS. Spirituality/religion was assessed by using the Duke Religion Index, Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being-Expanded, and Brief RCOPE measures. Mediating factors included social support, self-esteem, healthy beliefs, and health status/health concerns. RESULTS: Approximately one-third of the patients felt that their life was better now than it was before being diagnosed with HIV/AIDS. A 1-SD increase in spirituality/religion was associated with a 68.50% increase in odds of feeling that life has improved--29.97% due to a direct effect, and 38.54% due to indirect effects through healthy beliefs (29.15%) and health status/health concerns (9.39%). Healthy beliefs had the largest effect on feeling that life had improved; a 1-SD increase in healthy beliefs resulted in a 109.75% improvement in feeling that life changed. CONCLUSIONS: In patients with HIV/AIDS, the level of spirituality/religion is associated, both directly and indirectly, with feeling that life is better now than previously. Future research should validate our new conceptual model using other samples and longitudinal studies. Clinical education interventions should focus on raising awareness among clinicians about the importance of spirituality/religion in HIV/AIDS.

Quantifying headache symptoms and other headache features from chart notes.

OBJECTIVES: To describe a method for quantifying headache symptoms/features in family practice charts for patients diagnosed with headache NOS (not otherwise specified, ICD-9: 784) and to determine the share of NOS headache diagnoses with clinical data strongly suggestive of migraine or probable migraine headache. BACKGROUND: Headache is one of the most common pain symptoms that brings patients to a family physician. However, the majority of headache sufferers do not receive a specific headache diagnosis when they visit physicians. METHODS: We examined the chart notes of 454 patients exclusively diagnosed with one or more ICD-9 coded headache NOS diagnoses from July 1, 1995 through December 31, 1999 at a large suburban, university-affiliated practice. We developed a template containing 20 headache items combining International Headache Society diagnostic criteria and additional headache symptoms/features, and decision rules for coding symptoms/features and collected data from patient charts. We then developed decision rules and reclassified NOS headaches into categories strongly suggestive of migraine, probable migraine headache, or other diagnosis. Our main outcome measure is the consistency in the application of decision rules and diagnostic criteria. RESULTS: With this method we estimate 3 in 10 (29%) headache NOS patients may have had migraine (8%) or probable migraine headache (21%). Reclassified migraine visits averaged 6.5 migraine symptoms and reclassified probable migraine headache visits 4.7 migraine symptoms. Logistic regression analysis supports the consistency of diagnostic criteria for classifying headache based on coded symptoms/features--our model correctly predicted 96% of visits. Evidence of physical examination was recorded at 75% of visits suggesting that physician attention is focused on elimination of secondary headache. CONCLUSIONS: We think the use of our rigorous procedures reveals that a substantial amount of migraine and probable migraine headache may be missed in everyday practice. We hope our findings will provide a basis for the development of diagnostic methods more closely suited to the needs of nonspecialists, and contribute to a better standard of care for headache patients seen in primary care practice. Finally, we are hopeful that other researchers will consider using our template and guideline procedures in their efforts to identify diagnostic patterns and study headache and other health problems.

Intergenerational transmission of prejudice, sex role stereotyping, and intolerance.

The attitudes of 111 ninth and eleventh graders and both of their biological parents were independently assessed for prejudice against people with HIV/ AIDS, homosexuals, Blacks, and fat people, as well as for male and female sex role stereotyping. This study corrected for two shortcomings in previous research: neglecting to assess both parents and assessing only a single domain of prejudice. We addressed the intergenerational transmission of prejudice and stereotyping using three competing models: same-sex, parent equivalent, and differential effects. Using multiple regressions in which parents' scores were entered separately, along with control variables, different maternal and paternal influences were detected. Mothers were the primary influence for prejudice regarding HIV/AIDS, fatness, and race, and fathers were the primary influence for male and female stereotyping and prejudice against homosexuals, supporting the differential effects model. We also established that prejudice and stereotyping in specific domains reflected a more general proclivity to be intolerant. In contrast to prejudice and stereotyping in specific domains, fathers and mothers about equally shaped the adolescents' intolerance, supporting the parent equivalent model.

Does financial self-efficacy explain gender differences in retirement saving strategies?

Research indicates that women remain less financially prepared for retirement than are men. Little research has examined the gender difference in use of retirement plans. The present research assessed the gender difference in use of employer-sponsored and private retirement plans, and sought to account for this difference. Social status and human capital factors, occupation and industry of employment, and sense of financial self-efficacy were expected to account for gender differences. Findings indicated gender has no relationship with use of private retirement plans. However, females were found to be less likely to use an employer-sponsored plan, and this was largely accounted for by gender differences in occupation.

Predicting the number of headache visits by type of patient seen in family practice.

OBJECTIVES: To examine the number of visits involving a headache diagnosis among patients to four family practice sites between July 1, 1995 and December 31, 1998. BACKGROUND: Although the majority of care-seeking headache sufferers are seen in the primary care setting, few studies have attempted to document the relationship between type of headache as diagnosed by the family practice physician, and number of the patient's headache visits. Design.-Secondary analysis of administrative claims data. METHODS: We compared headache visits per person-year by the age and sex of patient among patients classified according to headache diagnosis received: tension-type only; headache not otherwise specified (NOS) only; migraine only; tension-type and headache NOS; tension-type and migraine; headache NOS and migraine, and migraine, tension-type, and headache NOS. Patients with an International Classification of Diseases (version 9) code of 346 were considered to have a diagnosis of migraine, with 307.81 representing tension-type headache, and 784 representing headache NOS. Age was measured from date of birth to initial visit in the study period and patients were subdivided into 5-year age groups. Person-years "at risk" for each diagnosis was measured from the time of initial visit during the study period to December 31, 1998. RESULTS: We examined data from 4112 patients who made 9322 visits with a headache diagnosis. We found that the average number of visits per person-year increases as the number of different types of headache diagnoses increased and were greatest for patients having migraine as opposed to headache NOS and tension-type diagnoses. CONCLUSIONS: Headache type is an important predictor of the number of office visits involving a headache diagnosis in family practice. Patients with multiple headache diagnoses have more visits. Patients with combinations of headache diagnoses involving migraine are the most frequent visitors.

Measurement of maternal alcohol consumption in a pregnant population.

Alcohol is a known teratogenic substance that operates under a dose-response mechanism. Before we conducted a larger study that examines the use of alcohol both before pregnancy and during pregnancy, it was important to pilot our method for measuring a pregnant mother's alcohol use that would allow us to capture the number of drinks consumed per day while addressing recall bias. The purpose of this study was 1) to pilot the Time Line Followback (TLFB) method developed by Sobell and Sobell (1992, Measuring Alcohol Use. Totowa, NJ: Humana Press) as a method for examining alcohol use during pregnancy and 2) to determine if the use of a study protocol that included biological markers of alcohol use would affect our ability to recruit subjects. Using a descriptive design, we tested our protocol for collecting alcohol use data with 10 mothers receiving prenatal care. We measured alcohol use using the TLFB method (Sobell and Sobell, 1992, Measuring Alcohol Use. Totowa, NJ: Humana Press, 1996). We also collected collected biological blood markers for heavy alcohol use. Of the 10 maternal subjects we recruited, 5 mothers (50%) reported alcohol use during pregnancy. We successfully recruited 10 out of 11 mothers approached and had a 100% retention rate for the second interview. The TLFB method is viable for measuring fetal alcohol exposure over the pregnancy, and the collection of blood samples did not impact our ability to recruit or retain mothers.

Current screening instruments related to alcohol consumption in pregnancy and a proposed alternative method.

Because alcohol is a known teratogenic substance that negatively affects the fetus, screening for alcohol use is included in maternal child texts for nurses. They present no standard screening approach, however. In the general literature, a multitude of screening instruments exist for the purpose of detecting maternal alcohol dependence but few allow the nurse to detect fetal alcohol exposure in the absence of maternal alcohol dependence. After a comparative analysis of existing screening instruments, we concluded that the Timeline Followback method has the most utility as a screening instrument to detect fetal exposure to alcohol. The purpose of this article is to present a critical review of current screening instruments related to alcohol consumption in pregnant women and to propose the use of the Timeline Followback method as the preferred approach.
