Factor Structure and Validity of the Parenting Stress Index-Short Form

The psychometric properties of the Parenting Stress Index-Short Form (PSI-SF) were examined in a sample of 185 mothers and fathers. Factor analysis revealed 2 reasonably distinct factors involving parental distress and dysfunctional parent-child interactions. Both scales were internally consistent, and these scales were correlated with measures of parent psychopathology, parental perceptions of child adjustment, and observed parent and child behavior. PSI-SF scores were related to parent reports of child behavior 1 year later, and the Childrearing Stress subscale was a significant predictor of a parental history of abuse.

Modeling computer interest in older adults: the role of age, education, computer knowledge, and computer anxiety.

We proposed a mediation model to examine the effects of age, education, computer knowledge, and computer anxiety on computer interest in older adults. We hypothesized that computer knowledge and computer anxiety would fully mediate the effects of age and education on computer interest. A sample of 330 older adults from local senior-citizen apartment buildings completed a survey that included an assessment of the constructs included in the model. Using structural equation modeling, we found that the results supported the hypothesized mediation model. In particular, the effect of computer knowledge operated on computer interest through computer anxiety. The effect of age was not fully mitigated by the other model variables, indicating the need for future research that identifies and models other correlates of age and computer interest. The most immediate application of this research is the finding that a simple 3-item instrument can be used to assess computer interest in older populations. This will help professionals plan and implement computer services in public-access settings for older adults. An additional application of this research is the information it provides for training program designers.

Everyday cognition: age and intellectual ability correlates.

The primary aim of this study was to examine the relationship between a new battery of everyday cognition measures, which assessed 4 cognitive abilities within 3 familiar real-world domains, and traditional psychometric tests of the same basic cognitive abilities. Several theoreticians have argued that everyday cognition measures are somewhat distinct from traditional cognitive assessment approaches, and the authors investigated this assertion correlationally in the present study. The sample consisted of 174 community-dwelling older adults from the Detroit metropolitan area, who had an average age of 73 years. Major results of the study showed that (a) each everyday cognitive test was strongly correlated with the basic cognitive abilities; (b) several basic abilities, as well as measures of domain-specific knowledge, predicted everyday cognitive performance; and (c) everyday and basic measures were similarly related to age. The results suggest that everyday cognition is not unrelated to traditional measures, nor is it less sensitive to age-related differences.

Cardiovascular intraindividual variability in later life: the influence of social connectedness and positive emotions.

Healthy normotensive men and women (N=33) underwent a 60-day diary assessment of emotions and cardiovascular functioning. Individual differences in social connectedness and mood were measured in questionnaires, and positive emotions, negative emotions, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were assessed daily for 60 consecutive days. Results confirmed that the cardiovascular undoing effect of positive emotions is evident primarily in the context of negative emotional arousal. The daily associations between positive emotions and cardiovascular outcomes were linked to individual differences in social connectedness. Controlling for individual differences in mood levels, multilevel regression analyses showed that social connectedness predicted extended positive emotion, diminished SBP and DBP reactivity, and more rapid SBP recovery from daily negative emotional states.

Mild Cognitive Impairment and Objective Instrumental Everyday Functioning: The Everyday Cognition Battery Memory Test

OBJECTIVES: To examine the performance subjects with and without mild cognitive impairment (MCI) on an objective measure of everyday or real‐world memory and subjective items assessing competency within the same instrumental domains; to determine whether the Everyday Cognition Battery (ECB) can uniquely predict MCI status.

Successful aging through digital games: Socioemotional differences between older adult gamers and Non-gamers

The purpose of this investigation was to examine differences in psychological functioning (e.g., well-being, affect, depression, and social functioning) between older adults who play digital games compared to those older adults that do not play digital games. Analysis was conducted on a sample of 140 independently living older adults with an average age of 77.47years (SD=7.31). Participants were divided into three groups (Regular, Occasional Gamers, and Non-gamers) - 60% of the sample was either a Regular or Occasional Gamer. Differences among the groups were found for well-being, negative affect, social functioning, and depression with Regular and Occasional Gamers performing better, on average, than Non-gaming older adults. Findings suggest that playing may serve as a positive activity associated with successful aging.

Individual differences in response to cognitive training: Using a multi-modal, attentionally demanding game-based intervention for older adults

The effectiveness of a game-based cognitive training intervention on multiple abilities was assessed in a sample of 39 older adults aged 60-77. The intervention task was chosen based on a cognitive task analysis designed to determine the attentional and multi-modal demands of the game. Improvements on a measure of attention were found for the intervention group compared to controls. Furthermore, for the intervention group only, initial ability scores predicted improvements on both tests of attention and spatial orientation. These results suggest cognitive training may be more effective for those initially lower in ability.

Putting Fun into Video Games for Older Adults

Our observations of players older than 65 suggested that they weighed costs and benefits when deciding whether or not to play video games. Current games can be higher in cost for seniors because of the perceptual and cognitive changes that tend to occur with age. When seniors choose to invest effort in overcoming those costs, it is often because they perceive a high benefit. Creating successful games for seniors will likely require designers to increase the perceived benefits of games, such as engagement, even more than lowering costs such as frustration, time, and money.

Competence in Everyday Activities as a Predictor of Cognitive Risk and Mortality

ABSTRACT This study examined the association of a performance-based measure of everyday functioning with clinically meaningful outcomes. Elderly participants in a prospective study of dementia were assessed at two occasions on the Everyday Problems Test for Cognitively Challenged Elderly (EPCCE), a performance-based measure of everyday functioning. Older adults who remained cognitively intact performed approximately 0.66 SD units higher on the EPCCE at both occasions than elders rated as impaired, when covarying on age, education, gender, and cognitive status. Relative to the nonimpaired participants, decline in EPCCE performance over a 2-year interval was significantly greater for impaired participants and those participants who transitioned from nonimpaired to impaired over the course of the study. Increased risk of mortality was associated with lower baseline scores and decline in EPCCE performance even after controlling for demographic variables and performance on the Mini-Mental State Examination. Given the clinical importance of identifying “at risk” elders for impairment, the findings from this study provide initial evidence for the predictive utility of performance-based measures of everyday functioning.

A GROWTH CURVE MODEL OF LEARNING ACQUISITION AMONG COGNITIVELY NORMAL OLDER ADULTS

ABSTRACT The objective of this study was to model recall and learning on the Auditory Verbal Learning Test using latent growth curve techniques. Participants were older adults recruited for the ACTIVE cognitive intervention pilot. A series of nested models revealed that an approximately logarithmic growth curve model provided optimal fit to the data. Although recall and learning factors were statistically uncorrelated, a fitted multivariate model suggested that initial recall was significantly associated with demographic characteristics but unrelated to health factors and cognitive abilities. Individual differences in learning were related to race/ethnicity, speed of processing, verbal knowledge, and global cognitive function level. These results suggest that failing to recognize initial recall and learning as distinct constructs clouds the interpretation of supraspan memory tasks.
