Comparative effectiveness of two interventions to increase colorectal cancer screening among females living in the rural Midwest
PURPOSE: To assess the comparative effectiveness of a tailored, interactive digital video disc (DVD) intervention versus DVD plus patient navigation (PN) intervention versus usual care (UC) on the uptake of colorectal cancer (CRC) screening among females living in Midwest rural areas. METHODS: As part of a larger study, 663 females (ages 50-74) living in rural Indiana and Ohio and not up-to-date (UTD) with CRC screening at baseline were randomize…
Psychometric development of a new body image scale for breast cancer survivors
The purpose of this study was to psychometrically test a body image scale for breast cancer survivors (BCS). Data ( n = 1127 BCSs) were obtained via telephone and mailed questionnaires. Psychometric testing was conducted using Cronbach's alpha, item-total correlations, factor analysis, linear regression, and Pearson's correlations. Data demonstrated a unidimensional seven-item scale with Cronbach's alpha = 0.88 and item-total correlations ranging…
Factors Associated with Adherence to Mammography Screening Among Insured Women Differ by Income Levels
Patient Health Questionnaire Anxiety and Depression Scale
OBJECTIVE: We examine the reliability and validity of the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS)-which combines the nine-item Patient Health Questionnaire depression scale and seven-item Generalized Anxiety Disorder scale-as a composite measure of depression and anxiety. METHODS: Baseline data from 896 patients enrolled in two primary-care based trials of chronic pain and one oncology-practice-based trial of depressio…
Factors associated with depressive symptoms in young long-term breast cancer survivors
Randomized trial of DVD, telephone, and usual care for increasing mammography adherence
The purpose of this study was to test an intervention to increase mammography screening in women 51-75 years of age who had not received a mammogram in the last 15 months. A total of 1681 women were randomized to (1) a mailed tailored interactive DVD, (2) a computer-tailored telephone counseling, or (3) usual care. Women with income below US$75,000 who were in the interactive DVD group had significantly more mammograms than women in usual care. W…
Depressive Symptom Clusters as Predictors of Incident Coronary Artery Disease
OBJECTIVE: Because it is not known whether particular clusters of depressive symptoms are associated with a greater risk of adverse cardiac outcomes, we compared the utility of four clusters in predicting incident coronary artery disease (CAD) events during a 15-year period in a large cohort of primary care patients 60 years and older. METHODS: Participants were 2537 primary care patients 60 years or older who were screened for depression between…
Emerging Adults With Type 1 Diabetes During the First Year Post-High School
Among 182 emerging adults with type 1 diabetes (93% White and 57% female), changes during the year post-high school were examined in perceptions of diabetes-specific conflict with parents, parent-youth shared responsibility, parental tangible aid, and parental autonomy support, as well as the moderating effects of living situation, gender, years with diabetes, and glycemic control. A linear mixed effects model, controlling for baseline values, te…
Impact of Dementia on Payments for Long-term and Acute Care in an Elderly Cohort
BACKGROUND: Older people with dementia have increased risk of nursing home (NH) use and higher Medicaid payments. Dementia's impact on acute care use and Medicare payments is less well understood. OBJECTIVES: Identify trajectories of incident dementia and NH use, and compare Medicare and Medicaid payments for persons having different trajectories. RESEARCH DESIGN: Retrospective cohort of older patients who were screened for dementia in 2000-2004 …
A Comparison and Cross-validation of Models to Predict Basic Activity of Daily Living Dependency in Older Adults
BACKGROUND: A simple method of identifying elders at high risk for activity of daily living (ADL) dependence could facilitate essential research and implementation of cost-effective clinical care programs. OBJECTIVE: We used a nationally representative sample of 9446 older adults free from ADL dependence in 2006 to develop simple models for predicting ADL dependence at 2008 follow-up and to compare the models to the most predictive published mode…

Accuracy of Self-Reported Health Services Use and Patterns of Care Among Urban Older Adults
BACKGROUND: Understanding older adults' volume and patterns of health service use is fundamental to efforts to improve the quality and efficiency of services. OBJECTIVE: To analyze the accuracy of older adults' self report of health services use and to determine the proportion of care obtained outside a defined urban academic health care system. RESEARCH DESIGN: Telephone survey of self-reports validated against data routinely archived in an elec…
Predictors of Mobility and Basic ADL Difficulty among Adults Aged 70 Years and Older
We use data from the 1993-1995 Assets and Health Dynamics of the Oldest-Old survey to estimate predictors of onset of mobility difficulty, onset of basic activity of daily living (ADL) difficulty, and improvement to no mobility difficulty. Onset of mobility difficulty occurred among 20% of those with no difficulty at baseline (n = 2,857) and was most likely among those 85 years of age or over, women, those with a body-mass index of 30 or over, an…
A Race- and Gender-Specific Replication of Five Dimensions of Functional Limitation and Disability
Activity of daily living (ADL) and instrumental ADL (IADL) data from the 1989 National Long-Term Care Survey (NLTCS) are used to replicate two domains of functional status with a total of five dimensions among them. LISREL analysis of the 14,415 Black and White older adults obtained from the 1989 NLTCS screen replicates three ADL disability dimensions (basic, household, and advanced) with few modifications, except among Black males. Similarly, an…
The Structure of Health Status Among Hispanic, African American, and White Older Adults
Activities of daily living (ADLs), instrumental ADLs, and disability markers have traditionally been the most common indicators of functional status. The study on Asset and Health Dynamics Among the Oldest Old (AHEAD) is used to replicate a five-dimensional measurement model composed of these observable indicators among the older adult self-respondents. The items available to measure upper body disability were found wanting, but the lower body di…
The effect of hip fracture on mortality, hospitalization, and functional status
OBJECTIVES: The purpose of this study was to prospectively assess the independent effect of hip fracture on mortalìty, hospitalization, and functional status. METHODS: Among 7527 members of the Longitudinal Study of Aging who were over age 70 at baseline, 368 persons with hip fracture occurring between 1984 and 1991 were identified. Median length of follow-up was 831 days. RESULTS: Hip fracture was significantly related to mortality (adjusted haz…
The Risk of Hospitalization for Congestive Heart Failure Among Older Adults
OBJECTIVES: The purpose of the study was to estimate the 8-year rate of hospitalization for congestive heart failure (CHF), to report the resources consumed, and to evaluate previously reported risk factors in a nationally representative sample of 7,286 older white and black adults. METHODS: Secondary analysis of baseline interview data was linked to Medicare hospitalization and death records for 1984 to 1991. Hospitalization for CHF was defined …
Consistency and Change in Functional Status among Older Adults Over lime
Consistency and change between 1984 and the last reinterview (either two, four, or six years later) on 22 individual functional status markers and the five summary scales that they form are examined among the 5,986 members of the Longitudinal Study on Aging who were reinterviewed at least once. At baseline, at least three-fifths of the respondents are without limitations on any individual marker. At the last reinterview, at least 43.4% of the res…
Age and the Sense of Control among Older Adults
Older adults are expected and frequently found to report less control than younger adults. In this study, we decompose this negative relationship between age and sense of control using nested multivariable linear regression models that serially introduce sociodemographic characteristics, socioeconomic factors, health status, and subjective religiosity and religious beliefs in a sample of 1,051 older adults attending the general medicine clinics o…
