A comparison of imputation techniques for handling missing data.

Researchers are commonly faced with the problem of missing data. This article presents theoretical and empirical information for the selection and application of approaches for handling missing data on a single variable. An actual data set of 492 cases with no missing values was used to create a simulated yet realistic data set with missing at random (MAR) data. The authors compare and contrast five approaches (listwise deletion, mean substitution, simple regression, regression with an error term, and the expectation maximization [EM] algorithm) for dealing with missing data, and compare the effects of each method on descriptive statistics and correlation coefficients for the imputed data (n = 96) and the entire sample (n = 492) when imputed data are included. All methods had limitations, although our findings suggest that mean substitution was the least effective and that regression with an error term and the EM algorithm produced estimates closest to those of the original variables.

Grandmothers and Caregiving to Grandchildren: Continuity, Change, and Outcomes Over 24 Months

PURPOSE Transitions in caregiving, such as becoming a primary caregiver to grandchildren or having adult children and grandchildren move in or out, may affect the well-being of the grandmother. DESIGN AND METHODS This report describes caregiving patterns at 3 time points over 24 months in a sample of 485 Ohio grandmothers and examines the effects of stability and change in grandmother caregiving roles (raising a grandchild, living in a multigenerational home, or not caregiving to grandchildren). Drawing on the Resiliency Model of Family Stress, the study examined caregiving stress and reward, intrafamily strain, social support, resourcefulness, depressive symptoms, mental and physical health, and perceived family functioning. Caregiver group, time of measurement, switching between caregiver groups, and baseline age, race, education, work status, and marital status were considered as independent variables within the context of a one-way treatment structure in a mixed-model multivariate analysis. RESULTS There were significant caregiver group effects for all variables, except mental health and resourcefulness. Grandmothers raising grandchildren reported the most stress, intrafamily strain, and perceived problems in family functioning, the worst physical health and more depressive symptoms, and the least reward and subjective support. Across groups, there were significant time effects, with worsening physical health and increased stress over time. Switching to higher levels of caregiving was associated with worsening physical health and increases in stress, intrafamily strain, and perceived problems in family functioning. IMPLICATIONS Recommendations for research and for practice, especially during times of caregiving transition or for grandmothers raising grandchildren, are discussed.

Longitudinal analysis of resourcefulness, family strain, and depressive symptoms in grandmother caregivers.

BACKGROUND Grandmothers living with grandchildren face stressors that may increase depressive symptoms, but cognitive-behavioral strategies, such as resourcefulness, may reduce the effects of stressors on mental health. PURPOSE This analysis examined the contemporaneous and longitudinal relationships among intra-family strain, resourcefulness, and depressive symptoms in 240 grandmothers, classified by caregiving status to grandchildren. METHODS Grandmothers raising grandchildren, grandmothers living in multigenerational homes, and non-caregivers to grandchildren reported on intra-family strain, resourcefulness, and depressive symptoms using mailed questionnaires at three time points over 5 years. Structural equation modeling was used to evaluate the mediating effects of resourcefulness and the relationships between variables. DISCUSSION Grandmother caregiver status had significant effects on depressive symptoms and intra-family strain but not on resourcefulness. At all waves, higher resourcefulness was associated with fewer depressive symptoms, which reduced appraisals of intra-family strain. CONCLUSIONS Interventions focused on strengthening resourcefulness could reduce depressive symptoms over time.

Grandmothers' Transitions in Caregiving to Grandchildren

Many grandmothers experience transitions in their caregiving roles to grandchildren as living arrangements change and parents assume more or less responsibility. The meanings of these transitions have received little attention, yet life transitions can be stressful. This qualitative study focuses on learning how grandmothers perceive these changes in household composition and the meanings these changes have. Analysis of semistructured telephone interviews with 26 transitioning grandmothers identified themes, including mixed feelings, changes in personal freedom, flexibility with unpredictable changes, spirituality as strength, commitment to grandchildren, and role transformation. The majority of status changes were from multigenerational or primary caregiving homes to non-coresident status. The meaning of the changes differed by status groups. The frequency of caregiving changes and the unique meanings of such changes extend our understanding of grandmothers as caregivers. Increased awareness and understanding of these meanings are important for nurses as they provide health care for this increasing population.

Recurrent symptoms: well-being and management.

Although most older adults report one or more symptoms of a chronic health problem, little attention has been paid to the report of these symptoms over time and whether different symptom patterns affect well-being and symptom management in community-dwelling elders. Therefore, this study examined whether community-dwelling older adults in Ohio, U.S.A. who experience consistently recurring (a) arthritis or (b) cardiopulmonary symptoms report more depression and worse self-assessed health and show more symptom management than those who report inconsistent symptoms and if there are differences in well-being and symptom management over time. This secondary analysis used longitudinal data collected from a random sample of 387 older adults who reported their health complaints in four interviews over 27 months time. Subjects were included in this analysis if they reported either arthritis (n = 321) or cardiopulmonary (n = 232) symptoms at one or more times during 27 months, and then were classified as having either consistent (occurring at all four time points) or intermittent/inconsistent (occurring at three or fewer time points) symptoms. Data analysis included t-tests, chi-square tests, and Repeated Measures ANOVA. Results indicate that those with consistent symptoms reported greater depression and worse self-assessed health than those with less consistent symptoms. Specifically, those with consistent cardiopulmonary symptoms became more depressed over time. Those with consistent cardiopulmonary complaints were more likely than those with an inconsistent pattern to use an illness label to describe their symptoms. Those with consistent arthritis symptoms tended to use more self-care at all time points, to label their symptoms as an illness, and were more likely to consult a physician as their symptoms persisted. The implications of symptom recurrence on well-being, symptom management and the concept chronicity are discussed.

Evaluating an Online Resourcefulness Training Intervention Pilot Test Using Six Critical Parameters

Few resources are available to help grandmother caregivers to grandchildren manage their complex family situations that may have immediate and long-term consequences for themselves and their families. Resourcefulness training is an intervention designed to help grandmothers improve their ability to deal with these problems. The purpose of this pilot study was to evaluate the necessity, feasibility, acceptability, fidelity, safety, and effectiveness (i.e., effect sizes) of an online, computer-based resourcefulness training intervention that was adapted from a face-to-face intervention. Twelve grandmothers raising or living with grandchildren participated in the pilot intervention that included (a) watching an instructional video on resourcefulness, (b) completing two online questionnaires over a 6-week time period, and (c) writing in an online journal every day for 4 weeks. Data are evaluated within the context of the six parameters important to intervention development. Qualitative and quantitative results provide initial support for all six parameters. Recommendations to improve aspects of the intervention are discussed.

Coping Resources, Loneliness, and Depressive Symptoms of Older Women With Chronic Illness

Chronic illness with its accompanying physical stressors poses a risk factor for loneliness and depression in later life. Testing a model of stress and coping, we examined the effects of three types of coping resources (religious coping; Selection, Optimization, and Compensation [SOC] adaptive strategies; and perceived social support) on the deleterious effects of chronic illness among older women. Community-dwelling older women (N = 138) with at least one chronic illness (M = 3.9, SD = 2.1) completed mailed questionnaires. Respondents reported multiple morbidities and 90% reported interference with daily life. Social support was associated with less loneliness and depression and mediated the relationship between physical health and loneliness. Our study demonstrates two distinct pathways to depressive symptoms: one through physical symptoms, pain, and disability, and another through the experience of loneliness. Findings support intervention approaches that address disability-related issues and loneliness, and assist older women with chronic illness in identifying and marshaling social support.

Grandmothers and Self-Management of Depressive Symptoms

HIGHLIGHTSPerceptions of depressive symptoms as an illness and in self‐management and consequences of symptoms differed by provider diagnosis.Grandmothers differed in their perception of symptom seriousness by CES‐D risk group, but not by caregiver group.Grandmothers who employed strategies to self‐manage their depression utilized a variety of methods.

Grandchildren’s Depressive Symptoms and Perceptions of Family Functioning: Protective and Influencing Factors

A recent increase in children living with grandparents places more children at increased risk for emotional, psychological, or behavioral problems. This study used the Resiliency Model of Family Stress, Adjustment, and Adaptation to examine how children’s living situation, parental monitoring, child’s resourcefulness, and perceived support affect depressive symptoms and perceived family functioning. Of participants, 36% (n = 56) lived with their parents only, 44% (n = 69) lived with a grandmother as their primary caregiver, and 20% (n = 31) lived in a multigenerational household. Results indicate parental monitoring and support affected perceptions of family functioning. Subjective support and resourcefulness affected depressive symptoms. No effects were found from living situation and demographic factors. Resourcefulness had the strongest effect on depressive symptoms, with a 3-point decrease in symptoms for each incremental increase in resourcefulness. This study provides insight into factors influencing children’s depressive symptoms and perceived family functioning, and provides direction for the development of future interventions.

Effects of chronic illness on daily life and barriers to self-care for older women: A mixed-methods exploration

ABSTRACT This mixed-methods study examined the subjective experience of living with chronic illness and identified barriers to self-care. Community-dwelling older women with chronic illness completed an initial (N = 138) and follow-up mailed survey 6 months later (N = 130). On average, participants reported four comorbid health conditions and the corresponding physical pain, activities curtailed or relinquished, and time and energy focused on managing health. Only 34% of participants practiced all 10 key self-care behaviors. Reported barriers to self-management included pain, lack of financial resources, and worry. In the regression analysis, having more depressive symptoms was a significant predictor of challenges with self-care behaviors.
