ADAPT Lab Resources Research Tools
Students who want to work in the ADAPT lab and have sufficient data analytical skills can have access to several data sets from past projects. These data sets can be used for thesis projects and are:
- Awareness of age-related change and other measures of subjective aging in adulthood (N=586)
- Awareness of age-related change and other measures of subjective aging in adulthood (N=396)
- Self-concept differentiation across the adult lifespan (N = 158)
- Stability of self-representations in adults (N = 189)
- Personality and personal goals in adults (N = 330)
- Attention control in goal pursuit and self-efficacy beliefs in college students (N = 443)
ADAPT RESEARCH Current Research Studies
The AgingPLUS Study
A large body of research has shown that most middle-aged (i.e., age 40-59) and older adults (i.e., age 60 and older) have room to improve their chances for healthy and successful aging. However, taking advantage of this “room for improvement” requires that a person engages on a regular basis in behaviors that are known, based on research, to improve the chances for healthy and successful aging.
One of these health-promoting behaviors is engagement in physical activity. There is increasing evidence that physical activity is the most promising non-pharmacological, noninvasive, and cost-effective method of health promotion in adults. However, the majority of adults do not engage in regular physical activity and with age people tend to become less physically active. Therefore, the percentage of adults meeting the recommended guidelines for physical activity that promotes healthy aging is quite low.
This raises the following question: How can we motivate middle-aged and older adults to become more physically active and to maintain this behavior over the long run so that they can reap long-term benefits? AgingPLUS is an educational program that was developed to address exactly this question.
What’s involved in the current study?
- The current study tests how well the AgingPLUS program works.
- Participation involves a two-month commitment:
- Month One: Learn! You will be randomly assigned to one of two educational programs. Each program will last four weeks, with one meeting per week.
- Month Two: Practice! Work on your own toward your personal physical activity goal. You will also receive a weekly phone call to touch base with you.
You may be eligible to participate if you are:
- age 50 or older and mostly sedentary;
- healthy enough (and willing) to increase your level of physical activity;
- willing to be randomly assigned to either educational program;
- willing to participate for the entire eight-week program and complete a brief follow-up questionnaire.
Registration is required! To register, please call (970) 491-5001.
ADAPT RESEARCH Completed Research Studies
Awareness of Age-Related Changed
The way in which people become aware of changes due to their own aging, termed Awareness of Age-Related Change, is the focus of a new research program in the ADAPT lab. Although people’s subjective experiences of growing older have been the focus of systematic inquiry since the 1950s, very little research has looked at how adults become aware of changes associated with growing older, and how they interpret such changes. We believe that learning more about AARC will provide us (a) with a better understanding of the nature of both positive and negative age-related changes; and (b) with valuable insights into the ways in which the aging process can be optimized. This work is done in collaboration with Prof. Hans-Werner Wahl of the University of Heidelberg, Germany.
The Daily Stress Interview Study
The Daily Stress Interview Study is a seven-year longitudinal study that investigates how adults cope with the stressors they encounter in daily life. The study started in 2003/2004 and the follow-up assessment was completed in 2010/2011. Participants were 239 adults, ranging in age from 18 to 89 years, who completed daily stress interviews and filled out daily diaries for 30 consecutive days. Data from the first wave of the project have provided information on the role of personal risk and resilience factors in coping with daily stress, as well as the role of age and personality characteristics in responding to daily stressors. Data from the second wave will allow us to address how short-term processes are linked to developmental change over a seven-year period. Analyses addressing questions along these lines are currently ongoing. Funding for the DAISI study was provided by grant R01 AG21147 from the National Institute on Aging, National Institutes of Health.
Cognitive-Emotional Integration in Adulthood and Aging
This project uses data from a 12-year longitudinal study of adult development and aging (Principal Investigators: Gisela Labouvie-Vief and Mark Lumley) to examine a variety of questions related to cognitive-emotional development across the adult lifespan. Our specific work focuses on the longitudinal development of emotion regulation strategies, coping and defense strategies, and aspects of emotional complexity. During the last wave of data collection, this study also collected momentary assessment data on affect and social experiences on a sub-sample of adults over a seven-day period. Funding for this longitudinal study was provided by grant R01 AG09203 from the National Institute on Aging, National Institutes of Health.
