The purpose of this study was to explore whether sedentary behavior cognitions explain physical activity (PA) intention and behavior when integrated within the theory of planned behavior framework (TPB). A random community sample of 206 adults and a sample of 174 undergraduate students completed measures of the TPB pertaining to PA and four popular leisure-time behaviors (TV viewing, computer use, sedentary hobbies, and sedentary socializing) and an adapted Godin Leisure-Time Exercize Questionnaire (community sample = cross-sectional, undergraduate sample = 2-week prospective). Results using ordinary least squares regression provided evidence that TV viewing intention explains additional variance in PA behavior, and affective attitude (community sample) and perceived behavioral control (undergraduate sample) towards TV viewing explains additional variance in PA intention even after controlling for PA-related TPB constructs. These results underscore the potential value of adding sedentary control interventions in concert with PA promotion. 相似文献

This research examines the early emergence of source-monitoring abilities. Previous research has consistently demonstrated that children as young as 3 to 4 years of age do well on simple versions of action-based source-monitoring tasks. Research on even younger children, however, remains lacking. In this study we examined whether 2½-year-olds could accurately recall source on a simplified task. For the procedure, we used an action-based task in which children collaborate with an experimenter to build a model farm. During construction, the child and the experimenter took turns placing items on the farm. After construction, children were administered a source memory test in which they were asked to recall who had placed each item. To more closely examine factors that influence source accuracy in this young population, we included two conditions that varied in terms of contextual support. In the no-context-cues condition, in line with typical source-monitoring tasks, children were asked the source test question while items were presented individually and the farm was not in view. In the context-cues condition, the original spatial array of farm items was left intact to provide additional cues for children's source decisions. The main finding was that children in both conditions showed high levels of source accuracy at test indicating a surprisingly early age of emergence for this ability. Also, as predicted, children in the context-cues condition were the most accurate in attributing source. 相似文献

This study examined the factor structure, internal consistency reliability and construct validity of the multidimensional health locus of control (MHLC) instruments developed by K. A. Wallston, B. S. Wallston, and DeVellis (1978) and Lau (Lau, 1982; Lau & Ware, 1981), Both measures were administered to a sample of Veterans Administration (VA) medical outpatients (N = 181). Only minimal evidence of convergence was found between corresponding scales of the two MHLC instruments. Low convergent validity appears attributable to the poor internal consistency reliability of the Lau-Ware subscales. Moreover, results of factor analysis largely supported the a priori factor structure of the K. A. Wallston et at. (1978) MHLC instrument but failed to support the factor structure of the Lau-Ware instrument, Health locus of control (HLC) dimensions that emerged from simultaneous factor analysis of both instruments were most consistent with a three-dimensional typology (i.e., Personal Control, Professional Control and Chance) rather than the four-dimensional typology proposed by Lau (Lau, 1982; Lau & Ware, 1981). Implications for HLC conceptualization and measurement are discussed. 相似文献

Research has suggested that women who experience postpartum depression are subsequently more likely to perceive their preschool-aged children as temperamentally difficult and maladjusted. However, previous studies have not controlled for the effects of concurrent depression levels on maternal ratings of child temperament or evaluated the accuracy of maternal reports. In the present study we assessed maternal and paternal ratings of child temperament 2 years after subjects had participated in a study of postpartum depression. The findings indicate that correlations between postpartum depression and subsequent child temperament ratings were accounted for statistically by concurrent levels of depression. Although fathers' ratings corroborated some aspects of maternal perceptions, levels of parental agreement were only moderately high. Moreover, discrepancies between the parents' reports were significantly associated with maternal depression, indicating that parental disagreement is more likely when the wife is dysphoric. 相似文献

Exposure to severe air pollution produces neuroinflammation and structural brain alterations in children. We tested whether patterns of brain growth, cognitive deficits and white matter hyperintensities (WMH) are associated with exposures to severe air pollution. Baseline and 1 year follow-up measurements of global and regional brain MRI volumes, cognitive abilities (Wechsler Intelligence Scale for Children-Revised, WISC-R), and serum inflammatory mediators were collected in 20 Mexico City (MC) children (10 with white matter hyperintensities, WMH+, and 10 without, WMH−) and 10 matched controls (CTL) from a low polluted city. There were significant differences in white matter volumes between CTL and MC children - both WMH+ and WMH− - in right parietal and bilateral temporal areas. Both WMH− and WMH+ MC children showed progressive deficits, compared to CTL children, on the WISC-R Vocabulary and Digit Span subtests. The cognitive deficits in highly exposed children match the localization of the volumetric differences detected over the 1 year follow-up, since the deficits observed are consistent with impairment of parietal and temporal lobe functions. Regardless of the presence of prefrontal WMH, Mexico City children performed more poorly across a variety of cognitive tests, compared to CTL children, thus WMH+ is likely only partially identifying underlying white matter pathology. Together these findings reveal that exposure to air pollution may perturb the trajectory of cerebral development and result in cognitive deficits during childhood. 相似文献

This research explores the spiritual benefits of travel for older adults and illustrates how travel meets seniors' self‐actualization and spiritual growth needs. The theoretical point of departure for this research is seniors' quest for meaning and self‐actualization, which act as push factors inducing older adults to travel. Semistructured depth interviews were conducted with 16 retired senior informants who had extensive travel experience. Using an interpretive method, this research reveals four key themes that illustrate the spiritual benefits of travel, thereby extending the growing literature on the motivations of senior travelers. These themes are described as “traveling generates meaning for older adults,” “traveling reveals the self to older adults,” “traveling encourages older adults to better understand others,” and “traveling enables older adults to better understand their relationship to nature”. In sum, the themes describe how older adults may meet their unique spiritual needs through travel and thereby enhance their spiritual development. This research represents one of a few studies examining senior tourism to employ an interpretive method and provides rich insights as a result. This research also extends the emerging research on spirituality in marketing by illustrating how the tourism industry may benefit from a perspective that considers the spiritual benefits of consumption. The research findings suggest that the intangible spiritual benefits of travel, in addition to the tangible benefits, should be highlighted in travel offers and tourism communications targeted to older adults.

Chaplains play an important role in supporting the mental health of current and former military personnel; in this study, the engagement of Department of Veterans Affairs (VA), Army, Navy, and Air Force chaplains with suicidality among their service users were examined. An online survey was used to collect data from 440 VA and 1,723 Department of Defense (DoD) chaplains as part of the VA/DoD Integrated Mental Health Strategy. Differences were noted for demographics, work setting characteristics, encountering suicidality, and self‐perceived preparation for dealing with suicidality. Compared to DoD chaplains, VA chaplains encounter more at‐risk service users, yet feel less prepared for dealing with suicidality. 相似文献

Although prior research has examined predictions of memory performance under conditions of interference at encoding, predictions
of memory performance have not been examined for interference introduced via cues at retrieval. This was investigated in the
present study by exposing participants to a random subset of to-be-recalled items just prior to retrieval (part-set cuing)
and then eliciting an overall prediction of memory performance. Across three experiments, participants in part-set cuing conditions
recalled proportionally fewer items than did participants who were not exposed to any cues. However, participants were unable
to predict the detrimental effect of part-set cues on memory performance in either a semantic (Experiment 1) or an episodic
(Experiment 2) memory task. Predictions were better calibrated after practice with part-set cuing, and there was evidence
that prior experience with part-set cuing transferred to predictions made for a different part-set cuing task (Experiment
3). This suggests that only under some conditions are participants sensitive to the diminished accessibility of memories wrought
by part-set cues and illustrates situations in which participants are or are not aware of variables at retrieval that influence
memory performance. 相似文献
