Despite widespread agreement about the importance of stress for health and well-being, scholars disagree about the types of variables that matter most. On one side, some argue that stress reactivity depends mostly on person-level variables, such as personality, while others contend that stress reactivity depends mostly on situation-level variables, for example chronicity. Researchers from a more integrative perspective assert that stress reactivity depends on an idiosyncratic interaction between person-level and stressor-level variables, for example the finding that lonely people are especially reactive to interpersonal tension. My dissertation reconciles these perspectives by leveraging crossed random effect modeling to determine the percent of stress reactivity attributable to each of these types of variables; the person, the situation, and the person-by-situation interaction. In Study 1, 368 undergraduate college students reacted to 60 unique situations in the context of normal daily life on two separate occasions. In Study 2, 955 adults from the Midlife in the U.S. study self-reported their reactivity to stressful situations encountered on each of eight days. Results from both studies suggest that these three types of variables account for the bulk, at least 70%, of stress reactivity in daily life. Moreover, all three types of variables emerged as important, as each factor contributed at least 20% of the overall variability in stress reactivity. Interestingly, both studies also found that situation-level variables mattered relatively more than the other two types of variables. I discuss these findings in relation to stress theory, stress-reduction interventions, and methodological innovations.

Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better health than those who were married in both 1998 and 2000. Married individuals reported fewer depressive symptoms than those who were not married.

Emotional Intelligence (EI) has been relatively unstudied after young adulthood. Yet there are a variety of reasons to expect that EI may be different at mid life than in young adulthood. Normative life experiences may lead to increases in EI, and as the array of different environments and experiences increases with age, one might expect greater individual differences in EI. Similarly, if EI is located somewhere at the intersection of personality and intelligence, as some have speculated, it may follow a course of structural differentiation similar to cognitive abilities. EI may be more closely linked to social variables such as loneliness and friendships at mid life, and its relation to established personality and ability factors such as the Big Five (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) and fluid and crystallized abilities may also vary with age. These hypotheses were investigated in samples of 292 young adults and 246 mid life adults, using the Schutte Self Report Emotional Intelligence Inventory, the NEO-Five Factor Personality Inventory, markers of crystallized and fluid ability from Horn's Crystallized/Fluid Sampler, and a variety of other measures. Mid life adults scored higher on overall EI scores, but evidenced no greater range of individual differences than did young adults. A series of exploratory and confirmatory factor analyses revealed no greater differentiation in the mid life sample either among dimensions of EI or between EI and personality and intelligence variables. Finally, EI appeared equally predictive of social variables in each sample. Results are discussed from the perspective of lifespan and aging literature on emotion, personality, and social functioning. Qualifications for the inference of age-related change in cross sectional designs are considered, along with advantages and disadvantages of factor-analytic and covariance structure modeling methodology. Implications, particularly for psychotherapy with each age group, are discussed.

Time poverty—the experience of insufficient time for rest, leisure, and self-development—has emerged as a critical issue in modern societies, intersecting with and potentially exacerbating social inequalities. This dissertation explores various dimensions of time poverty in the United States and South Korea. Through three interconnected studies, I examine long-term trends in relative time poverty, the association between time poverty and life satisfaction, and cohort effects on subjective and relative time poverty. The first paper examines time poverty trends among adults in the United States over the last 20 years. Using the 2003-2022 American Time Use Survey, I show long-term trends in time poverty rates for the US adult population, analyzing variations by key sociodemographic factors including gender, family structure, and race/ethnicity. Time poverty rates initially decreased from the early 2000s through the early 2010s, followed by an upward trend starting in 2013, with a brief dip during the 2020 COVID-19 peak and reaching a high point in 2022. Throughout the study period, time poverty was most prevalent among women, adults living with multiple young children, and individuals of Asian, Native Hawaiian, Pacific Islander, or Hispanic descent. Logistic regression analyses confirmed that being a woman, having children, and engaging in paid work were significantly associated with higher odds of experiencing time poverty. The second paper investigates the association between time poverty and life satisfaction among working-age adults in South Korea. Using the 2019 Korean Time Use Survey, I conducted descriptive analyses and employed generalized ordered logistic regression to examine the relationship between time poverty and life satisfaction. Time poverty was measured in both subjective and relative terms. Results showed that subjective time poverty was more common than relative time poverty among working-age adults, with both types most pronounced between ages 35 and 44 and more prevalent among men than women. Regression models demonstrated a significant negative association between subjective time poverty and life satisfaction, with the largest effects observed among those reporting severe subjective time poverty. The association between relative time poverty and life satisfaction appeared mostly statistically insignificant. The third paper studies how cohort membership influences subjective and relative time poverty among Korean adults across different age groups and periods. Utilizing four waves of the Korean Time Use Survey data from 2004 to 2019, I employed age-period-cohort detrended models to detect nonlinear fluctuations around linear trends for cohort-specific deviations. Results revealed a general decline in occasional subjective time poverty across cohorts but an increase in chronic subjective time poverty and relative time poverty among those in their 20s and 30s across successive cohorts. Significant variations in subjective and relative time poverty were found across different cohorts, with notable shifts occurring between the 1970s and 1980s cohorts. Subgroup analyses indicated varying effects based on gender, education level, and number of children in the household, with more prominent effects observed for cohorts born in the 1970s. By investigating these aspects across different contexts, this dissertation highlights the complex nature and far-reaching consequences of time poverty on individual well-being and social dynamics. The findings underscore how time poverty reflects changing societal values and structures, particularly in relation to work-life balance, family dynamics, and cohort shifts in time use patterns. This research contributes to our understanding of evolving social inequalities and may inform policies aimed at promoting more equitable use of time across diverse populations, ultimately addressing the broader implications of time poverty in modern societies.
