Aging Parents' Daily Support Exchanges With Adult Children Suffering Problems.

OBJECTIVES: When adult children incur life problems (e.g., divorce, job loss, health problems), aging parents generally report providing more frequent support and experiencing poorer well-being. Yet, it is unclear how adult children's problems may influence aging parents' daily support exchanges with these children or the parents' daily mood. METHODS: Aging parents from the Family Exchanges Study Wave 2 (N = 207, Mage = 79.86) reported providing and receiving emotional support, practical support, and advice from each adult child each day for 7 days. Parents also rated daily positive and negative mood. RESULTS: Multilevel models showed that aging parents were more likely to provide emotional and practical support to adult children incurring life problems than children not suffering problems. Parents were also more likely to receive emotional support and advice from these children with problems. Further, parents reported less negative mood on days when providing practical support to children with problems. DISCUSSION: Examining daily support exchanges adds to our understanding of how children's problems influence parent-child ties in late life. Prior research suggests that children's problems upset parents. In this study, however, it appears that supporting adult children who suffer problems may alleviate aging parents' distress regarding such children.

Pairs of Genetically Unrelated Look-Alikes : Further Tests of Personality Similarity and Social Affiliation.

Relationships of physical resemblance to personality similarity and social affiliation have generated considerable discussion among behavioral science researchers. A "twin-like" experimental design (involving genetically unrelated look-alikes, U-LAs) explores associations among resemblance in appearance, the Big Five personality traits, self-esteem, and social attraction within an evolutionary framework. The Personality for Professionals Inventory (PfPI), NEO/NEO-FFI-3, Rosenberg Self-Esteem Scale, and a Social Relationship Survey were variously completed by 45 U-LA pairs, identified from the "I'm Not a Look-Alike" project, Mentorn Media, and personal referrals. The mean U-LA intraclass correlations were negligible for all Big Five personality traits on the PfPI and NEO/NEO-FFI-3 (ri = -.02 and - .04, respectively). In contrast, mean ri values of .53 and .15 for monozygotic (MZA) and dizygotic (DZA) reared-apart twins, respectively, have been reported for these personality measures. The U-LA self-esteem correlation (ri = -.18) was also below the correlations reported for MZ and DZ reared-together twins (ri = .31 and .13, respectively). Finally, far fewer U-LAs expressed close social relationships (20%) than MZA (80%) and DZA (65%) twins. The present study extends earlier findings indicating that appearance is not meaningfully related to personality similarity and social relatedness. The criticism that MZ twins are alike in personality because their matched looks invite similar treatment by others is refuted. A more judicious interpretation is reactive genotype-environment correlation, namely that MZ twins' similar personalities evoke similar reactions from others. MZ twins' close social relations most likely derive from their perceptions of genetically based within-pair similarities that are lacking in U-LAs.

Aging Parents' Disabilities and Daily Support Exchanges With Middle-Aged Children.

Background and Objectives: Aging parents often incur disabilities in activities of daily living, which may limit their ability to give support and necessitate increased support from middle-aged children. Research has predominantly assessed disabled parents' retrospective reports of receiving support, but we know little about their daily support exchanges with middle-aged children. This study examined practical support, emotional support, and advice that aging parents with and without disabilities provided and received from middle-aged children, and links between these support exchanges and parents' daily mood. Research Design and Methods: Aging parents (N = 202, Mage = 79.86) from the Family Exchanges Study II indicated their disabilities and background characteristics. They also reported daily exchanges of practical, emotional support, and advice with each middle-aged child and their daily mood for 7 days. Results: Multilevel models revealed that aging parents suffering disabilities were equally likely to provide each type of support but more likely to receive practical support. Aging parents' disabilities seemed to buffer the effects of these support exchanges, such that parents with disabilities versus parents without disabilities reported less negative mood when providing practical support or emotional support, and more positive mood when receiving practical support. Discussion and Implications: Exploring the role of aging parents' disabilities in their daily support exchanges with middle-aged children expands on the literature of late-life disabilities and parent-child ties. Despite increasing disabilities, aging parents continue to engage in support exchanges with middle-aged children in daily life and these parents appear to benefit from such involvement.

A Family Affair: Family Typologies of Problems and Midlife Well-Being.

Background and Objectives: Midlife adults are a "pivot" generation, responding to parents' and grown children's problems. Yet, some midlife adults may have families where multiple members suffer sorrows, whereas other midlife adults may have families with few problems. This study examined: (a) typologies of problems across generations and (b) associations between profiles of problems and midlife adults' well-being. Research Design and Methods: Midlife adults (N = 633) reported their own, each parent's (n = 868), and grown child's (n = 1,785) physical (e.g., injury, cancer), psychological (e.g., anxiety, addiction), and lifestyle problems (e.g., divorce, job loss), and parents' functional disabilities. Midlife adults reported their own depressive symptoms. Results: Latent profile analysis revealed four family typologies: (a) lowest problems across generations (n = 364), (b) offspring and midlife adult moderate problems, parent high physical problems and disability (n = 165), (c) offspring and parent moderate problems (n = 90), and (d) offspring highest problems (n = 14). Midlife adults in the lowest problems group (Profile a) reported higher income and fewer depressive symptoms than midlife adults in the other groups. Discussion and Implications: Midlife adults cope with challenges when grown children or parents suffer problems, and their well-being may suffer as a result. In this study, regardless of the profile, higher problems in either generation were associated with more depressive symptoms for midlife adults.

Twins and virtual twins: Do genetic (as well as experiential) factors affect developmental risks?

Factors underlying developmental delays and psychosocial risks are of interest to international adoption communities. The current study administered a Pre-Adoption Adversity (PAA) Questionnaire to mostly American parents raising (a) adopted Chinese twins or (b) same-age unrelated adopted siblings. A goal was to replicate earlier analyses of pre-adoption adversity/adjustment among adopted preschool-age Chinese girls. A second goal was to conduct genetic analyses of four content areas (Developmental Delays at Adoption, Initial Adaptation to Adoption, Crying/Clinging, and Refusal/Avoidance) derived from the PAA Questionnaire. A key finding was that age at adoption added less than other predictors to adoptees' externalizing and internalizing behaviors. Family factors (e.g., parental education) contributed significantly to behavioral outcomes among the adopted Chinese twins. Genetic effects were indicated for all four content areas, with shared environmental effects evident for Developmental Delays at Adoption and Crying/Clinging. Future investigators should consider incorporating genetically sensitive designs into developmental research programs.

Children affected by maternal HIV/AIDS: feasibility and acceptability trial of the Children United with Buddies (CUB) intervention.

Past research has shown that young children affected by maternal HIV present with elevated stress/anxiety and negative well-being. This pilot intervention for children aged 7-14 affected by maternal HIV targeted improving positive child-mother communication, improving HIV/AIDS knowledge and reducing anxiety (especially related to transmission), and lessening feelings of stigma. Each of the three child intervention sessions included behavioral skills training and a themed craft exercise; mothers attended an open discussion group while the children attended their sessions. Study participants were 37 child-mother pairs. The study design was a randomized two-group pretest-posttest experimental design. The intervention sessions were audiotaped for transcription. Results showed significant decreases in anxiety and worry for children in the intervention group, and increases in happiness and knowledge regarding HIV/AIDS transmission. Intervention group mothers reported greater social support. Qualitative findings for the intervention group children and mothers also support these findings. Early intervention reduces child stress, and may affect longer-term outcomes.

Active transport between home and school assessed with GPS: a cross-sectional study among Dutch elementary school children.

BACKGROUND: Active transport to school is associated with higher levels of physical activity in children. Promotion of active transport has therefore gained attention as a potential target to increase children's physical activity levels. Recent studies have recognized that the distance between home and school is an important predictor for active travel among children. These studies did not yet use the promising global positioning system (GPS) methods to objectively assess active transport. This study aims to explore active transport to school in relation to the distance between home and school among a sample of Dutch elementary school children, using GPS. METHODS: Seventy-nine children, aged 6-11 years, were recruited in six schools that were located in five cities in the Netherlands. All children were asked to wear a GPS receiver for one week. All measurements were conducted between December 2008 and April 2009. Based on GPS recordings, the distance of the trips between home and school were calculated. In addition, the mode of transport (i.e., walking, cycling, motorized transport) was determined using the average and maximum speed of the GPS tracks. Then, proportion of walking and cycling trips to school was determined in relation to the distance between home and school. RESULTS: Out of all school trips that were recorded (n=812), 79.2% were classified as active transport. On average, active commuting trips were of a distance of 422 meters with an average speed of 5.2 km/hour. The proportion of walking trips declined significantly at increased school trip distance, whereas the proportion of cycling trips (ß=1.23, p<0.01) and motorized transport (ß=3.61, p<0.01) increased. Almost all GPS tracks less than 300 meters were actively commuted, while of the tracks above 900 meters, more than half was passively commuted. CONCLUSIONS: In the current research setting, active transport between home and school was the most frequently used mode of travel. Increasing distance seems to be associated with higher levels of passive transport. These results are relevant for those involved in decisions on where to site schools and residences, as it may affect healthy behavior among children.

Fullerton Virtual Twin Study: an update.

Virtual twins (VTs) are same-age unrelated siblings reared together from early infancy. These unique sibling sets replicate twinship, but without the genetic link. The first VT pair was identified and studied at the University of Minnesota in 1990, launching the development of the Fullerton Virtual Twin Study at California State University, Fullerton (CSUF) in 1991. The registry currently includes 151 pairs, mostly children, with new pairs identified on a continuous basis. Research with VTs includes studies of general intelligence, body size, interpersonal trust, social coordination, social networks, and parenting. In some cases, VTs have been studied in conjunction with pairs of monozygotic twins, dizygotic twins, full siblings, and friends as part of TAPS (Twins, Adoptees, Peers and Siblings), a collaborative project conducted between CSUF and the University of San Francisco, 2002-2006. VTs will also serve as a comparison group for epigenetic analyses of young Chinese twins reared apart and together.

Implementing Twitter in a health sciences library.

The NYU Health Sciences Libraries created an account on Twitter, a microblogging service, as a new outreach tool marketed to students, faculty, and staff. The team used Twitter to promote resources, events, and news. Twitter is a part of a pipeline of information that also includes the library's Web site and Facebook. Although it is difficult to measure the effectiveness of a social networking tool, the overhead of using Twitter is so low that it merits consideration.

Web-based gerontology courses: how do they measure up?

This study compared Web-based and lecture-based Gerontology and Psychology of Aging courses in terms of student performance, demographic and academic characteristics of students enrolled in the courses, and extent to which these characteristics differentially predicted outcomes of learning in the two course types. Participants for this study were 289 undergraduate students who completed a Psychology of Aging or Gerontology course, taught in either a Web-based or lecture-based format. Evaluation of student performance indicated percentage of points earned in the two course types did not differ significantly. Although students in Web-based courses tended to be older and were more likely to be upperclassmen than students in lecture-based courses, student profiles did not differ in terms of gender, race, grade point average, and Scholastic Assessment Tests (SAT) scores. Additionally, demographic and academic variables did not differentially predict course performance. The results of this study suggest a similar market in terms of demographic and academic characteristics of students for Web-based and lecture-based gerontology courses. Moreover, the findings suggest student learning outcomes in the two course formats are comparable.

Habitual traffic noise at home reduces cardiac parasympathetic tone during sleep.

The relationships between road and rail traffic noise with pre-ejection period (PEP) and with respiratory sinus arrhythmia (RSA) during sleep, as indices of cardiac sympathetic and parasympathetic nervous system tone, were investigated in the field (36 subjects, with 188 and 192 valid subject nights for PEP and RSA, respectively). Two analyses were conducted. The first analysis investigated the overall relationships across the entire sleep period. A second analysis investigated differences in the relationships between the first and second halves of the sleep period. Separate multilevel linear regression models for PEP and RSA were employed. Potential covariates for each model were selected from the same pool of variables, which included: gender, age, body-mass index, education level, traffic noise source type, intake of medication, caffeine, alcohol and cigarette smoke, and hindrance during sleep due to the ambulatory recordings. RSA models were adjusted for respiration rate. Mean indoor traffic noise exposure was negatively related to mean RSA during the sleep period, specifically during the second half of the sleep period. Both respiration rate and age were negatively associated with RSA. No significant relationships were observed for PEP. The results indicate that higher indoor traffic noise exposure levels may lead to cardiac parasympathetic withdrawal during sleep, specifically during the second half of the sleep period. No effect of indoor traffic noise on cardiac sympathetic tone was observed.
