Stress Generation, Avoidance Coping, and Depressive Symptoms: A 10-Year Model.

This study examined (a) the role of avoidance coping in prospectively generating both chronic and acute life stressors and (b) the stress-generating role of avoidance coping as a prospective link to future depressive symptoms. Participants were 1,211 late-middle-aged individuals (500 women and 711 men) assessed 3 times over a 10-year period. As predicted, baseline avoidance coping was prospectively associated with both more chronic and more acute life stressors 4 years later. Furthermore, as predicted, these intervening life stressors linked baseline avoidance coping and depressive symptoms 10 years later, controlling for the influence of initial depressive symptoms. These findings broaden knowledge about the stress-generation process and elucidate a key mechanism through which avoidance coping is linked to depressive symptoms.

Social support, coping, and depressive symptoms in a late-middle-aged sample of patients reporting cardiac illness.

This study tests a 1-year predictive model of depressive symptoms in a late-middle-aged sample of patients reporting diagnoses of cardiac illness. Results based on 325 individuals (248 men and 77 women) diagnosed with chronic cardiac illness, 71 individuals (52 men and 19 women) diagnosed with acute cardiac illness, and 219 healthy controls (129 men and 90 women) strongly supported the hypotheses. Compared with healthy persons, individuals with chronic and those with acute cardiac illness reported more depressive symptoms at follow-up. Women overall showed more depressive symptoms than did men, and women with cardiac illness were particularly vulnerable to behavioral manifestations of depressive symptoms. Integrative time-lag and prospective structural equation models indicated that, for individuals with cardiac illness, social support and adaptive coping strategies predicted fewer depressive symptoms.

Social context, coping strategies, and depressive symptoms: an expanded model with cardiac patients.

This research broadened and refined a resources model of coping to encompass negative as well as positive aspects of social relationships and examined this expanded conceptualization in a 4-year prospective model with 183 cardiac patients (140 men and 43 women). Social support and social stressors in the family and extrafamily domains contributed significantly to a common social context latent construct. In addition, this conceptualization of social context was significantly related to depressive symptoms 4 years later. Especially important conceptually, coping strategies functioned as a mechanism through which both social support and social stressors related to subsequent depressive symptoms. Moreover, positive and negative aspects of social relationships made essentially unique contributions in predicting subsequent coping efforts.

Approach and avoidance coping responses among older problem and nonproblem drinkers.

The Coping Responses Inventory (CRI) was used to study coping among older problem and nonproblem drinkers. The CRI organizes coping efforts according to their focus (approach or avoidance) and method (cognitive or behavioral). Compared with nonproblem drinkers, older problem drinkers were more likely to use cognitive and behavioral avoidance responses to manage life stressors. Problem drinkers who experienced more negative life events and more severe stressors used both more approach and more avoidance coping. Those who had more financial and social resources relied more on approach and less on avoidance coping. Problem drinkers who relied more on avoidance coping tended to have more drinking problems and to report more depression and physical symptoms and less self-confidence. Positive reappraisal was associated with less depression and more self-confidence.

The drinking problems index: A measure to assess alcohol-related problems among older adults

Research on problem drinking among older adults has been hampered by the lack of specialized instruments to assess drinking problems. In this paper, we examine the psychometric properties of a 17-item measure specifically designed to assess drinking problems in this population. The Drinking Problems Index (DPI) exhibits excellent psychometric properties, with an internal consistency reliability estimate of .94, a cross-temporal correlation over a 1-year interval of .66, and cross-sectional correlations with alcohol consumption at two points a year apart of .37 and .42. In addition, the construct validity of the DPI is supported by significant concurrent correlations indicating that persons who have more drinking-related problems experience more depression, have less self-confidence, and participate in fewer social activities. Consistent with the high internal consistency reliability estimate, a factor analysis confirmed that the measure is largely unifactorial. Overall, the findings suggest that the DPI is a reliable and valid instrument for assessing problems associated with drinking in surveys of older persons.

Older adults' alcohol consumption and late-life drinking problems: a 20-year perspective.

AIMS The aim of this study was to identify changes in patterns of alcohol consumption over a 20-year interval among older women and men, and to examine the associations between guideline-defined excessive drinking and late-life drinking problems. DESIGN, PARTICIPANTS AND MEASURES: A community sample of 719 adults between 55 and 65 years of age who consumed alcohol at or prior to baseline participated in a survey of alcohol consumption and drinking problems and was followed 10 years and 20 years later. FINDINGS The likelihood of excessive drinking declined over the 20-year interval as adults matured into their 70s and 80s. However, at ages 75-85, 27.1% of women and 48.6% of men consumed more than two drinks per day or seven drinks per week. At comparable guideline levels of alcohol consumption, older men were more likely to have drinking problems than were older women. Consumption of more than two drinks per day or seven drinks per week was identified as a potential conservative guideline for identifying excessive drinking associated with an elevated likelihood of drinking problems. CONCLUSIONS A substantial percentage of older adults who consume alcohol engage in guideline-defined excessive drinking and incur drinking problems. The finding that older men may be more likely than older women to experience problems when they drink beyond guideline levels suggests that alcohol guidelines for men should not be set higher than those for women.

Late-Life Alcohol Consumption and 20-Year Mortality

BACKGROUND Growing epidemiological evidence indicates that moderate alcohol consumption is associated with reduced total mortality among middle-aged and older adults. However, the salutary effect of moderate drinking may be overestimated owing to confounding factors. Abstainers may include former problem drinkers with existing health problems and may be atypical compared to drinkers in terms of sociodemographic and social-behavioral factors. The purpose of this study was to examine the association between alcohol consumption and all-cause mortality over 20 years among 1,824 older adults, controlling for a wide range of potential confounding factors associated with abstention. METHODS The sample at baseline included 1,824 individuals between the ages of 55 and 65. The database at baseline included information on daily alcohol consumption, sociodemographic factors, former problem drinking status, health factors, and social-behavioral factors. Abstention was defined as abstaining from alcohol at baseline. Death across a 20-year follow-up period was confirmed primarily by death certificate. RESULTS Controlling only for age and gender, compared to moderate drinkers, abstainers had a more than 2 times increased mortality risk, heavy drinkers had 70% increased risk, and light drinkers had 23% increased risk. A model controlling for former problem drinking status, existing health problems, and key sociodemographic and social-behavioral factors, as well as for age and gender, substantially reduced the mortality effect for abstainers compared to moderate drinkers. However, even after adjusting for all covariates, abstainers and heavy drinkers continued to show increased mortality risks of 51 and 45%, respectively, compared to moderate drinkers. CONCLUSIONS Findings are consistent with an interpretation that the survival effect for moderate drinking compared to abstention among older adults reflects 2 processes. First, the effect of confounding factors associated with alcohol abstention is considerable. However, even after taking account of traditional and nontraditional covariates, moderate alcohol consumption continued to show a beneficial effect in predicting mortality risk.

High-Risk Alcohol Consumption and Late-Life Alcohol Use Problems

OBJECTIVES We used several different guidelines for appropriate alcohol use to identify patterns of high-risk alcohol consumption among older women and men and examined associations between these patterns and late-life alcohol use problems. METHODS A sample of 1291 older adults participated in a survey of alcohol consumption and alcohol use problems and was studied again 10 years later. RESULTS Depending on the guideline, 23% to 50% of women and 29% to 45% of men engaged in potentially unsafe alcohol use patterns. The likelihood of risky alcohol use declined over the 10 years; however, the numbers of drinks consumed per week and per day were associated with alcohol use problems at both assessment intervals. CONCLUSION Our findings imply that guidelines for alcohol consumption should be no more liberal for older men than for older women.

Older adults’ health and late-life drinking patterns: A 20-year perspective

Objectives: This study focused on the associations between older adults’ health-related problems and their late-life alcohol consumption and drinking problems. Methods: A sample of 719 late-middle-aged community residents (55–65 years old at baseline) participated in a survey of health and alcohol consumption and this survey was followed 10 years and 20 years later. Results: Health-related problems increased and alcohol consumption and drinking problems declined over the 20-year interval. Medical conditions, depressive symptoms, medication use, and acute health events were associated with a higher likelihood of abstinence; acute health events were also associated with less alcohol consumption. In contrast, reliance on alcohol to reduce pain was linked to more alcohol consumption. Moreover, an individuals overall health burden and reliance on alcohol to reduce pain were associated with more drinking problems. Reliance on alcohol to reduce pain potentiated the association between health burden, alcohol consumption and drinking problems. Conclusion: Older adults who have more health problems and rely on alcohol to manage pain are at elevated risk for drinking problems. Health care providers should target high-risk older adults, such as those who drink to reduce pain, for screening and brief interventions to help them identify new ways to cope with pain and curtail their drinking.

Older adults’ health and changes in late-life drinking patterns

This study focused on the prospective associations between older adults’ health-related problems and their late-life alcohol consumption and drinking problems. A sample of 1,291 late-middle-aged community residents (55–65 years old at baseline) participated in a survey of health and alcohol consumption, and was followed one year, four years, and 10 years later. Health-related problems increased and alcohol consumption and drinking problems declined over the 10-year interval. Medical conditions, physical symptoms, medication use, and acute health events predicted a higher likelihood of abstinence and less frequent and lower alcohol consumption. However, overall health burden predicted more subsequent drinking problems, even after controlling for alcohol consumption and a history of heavy drinking and increased drinking in response to stressors. Among older adults, increased health problems predict reduced alcohol consumption but more drinking problems. Older adults with several health problems who consume more alcohol are at elevated risk for drinking problems and should be targeted for brief interventions to help them curtail their drinking.
