Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads. 相似文献

Carsharing originated in Europe and then expanded to developed countries such as the United States. With the revival and popularity of the “Sharing Economy,” carsharing has remarkably increased in China in recent years. Carsharing has increased convenience for individuals without private cars and is changing the traditional view of car ownership. Chinese college students are a large, highly educated group with low incomes and low rates of car ownership. Understanding the determinants of Chinese college students' intention to carshare is critical to promote carsharing services. In this research, an expanded version of the theory of planned behavior, which contains environmental concern, is the theoretical research framework. The model was empirically tested by using the questionnaire data of 356 college students from four universities in Qingdao, China. The results indicate that subjective norm and the perceived behavioral control are directly and positively associated with Chinese college students’ intention to use carsharing, and attitude and environmental concern have no direct correlation with the intention. Environmental concern has a significant direct effect on attitude, subjective norm, and perceived behavioral control. In addition, environmental concern indirectly impacts Chinese college students’ intention to use carsharing through subjective norm and perceived behavioral control. The findings yield practical insights for carsharing organizations and transportation planners. Based on these results, limitations of this study and suggestions for further research are discussed. 相似文献

ObjectivesSelf-efficacy is one of the most reliable correlates of physical activity, yet a growing body of literature has demonstrated that traditional self-efficacy measures may be flawed because they measure perceived capability and other constructs such as motivation. This study adds to this evidence base by comparing a standard self-efficacy measurement group and two measurement conditions that may provide greater validity: motivation held constant (i.e., adding “If you really wanted to” at the beginning of the item) and vignette (i.e., adding a clarifying vignette before the item). The first objective of this study was to compare these groups regarding self-efficacy scores. The second objective was to examine whether physical activity level (i.e., adhering to physical activity guidelines or not) interacted with measurement condition.DesignRandomized cross-sectional design with three independent groups.MethodParticipants were 444 undergraduate students (M age in years = 21.10, SD = 3.73) who completed an online survey measuring physical activity self-efficacy and behaviour.ResultsThe vignette group had higher self-efficacy scores than the standard and motivation held constant groups. Scores were also higher among those adhering to guidelines and there were no differences between the groups for physically active individuals. Finally, among those not adhering to the guidelines, the vignette group had especially high scores compared to the other groups.ConclusionsThis study demonstrated that reading a vignette prior to completing a self-efficacy item clarifies the meaning of the item thereby improving validity of the measure. 相似文献

本研究探讨了控制感、自我认同、对政策支持的感知等因素如何影响老年人的生命意义感。通过对300多名来自北京、香港和台北的老年人的调查,发现控制感和政策支持对老年人生命意义感的影响显着,二者不仅主效应显着,同时存在交互作用。进一步的分析还发现:政策支持在控制感与生命意义感的关系中起调节作用——高政策支持感增强了控制对生命意义感的正向作用;自我认同在控制感与生命意义感的关系中起部分中介作用。结果对积极应对老龄化问题与增进老年人身心健康有重要的理论和现实意义。 相似文献

The relations among anxiety sensitivity, perceived control, and agoraphobia were examined in 239 patients diagnosed with panic disorder (PD). Most patients exhibited agoraphobia accompanying their PD (98% situational avoidance; 90% experiential avoidance; and 80% endorsed interoceptive fear and avoidance). Anxiety sensitivity and perceived emotional control were associated with agoraphobia, and perceived threat control was found to moderate the relationship between anxiety sensitivity and agoraphobia. Lower levels of perceived control were associated with a stronger relationship between anxiety sensitivity and agoraphobia. Results were consistent for self-reported and clinician-rated agoraphobia. Implications for the role of perceived control in agoraphobia development and treatment are discussed. 相似文献

It is well known that a flat ellipse rotating in the frontoparallel plane appears, after brief inspection, as a rigid circular
disc tilting back and forth in a 3-D space. We here report that rotation of a grey-shaded ellipse on a white or on a black
background produces the compelling illusion of a dark smoke or a dazzling fog (depending on the conditions of the background)
moving in front of a completely white or completely black tilting disc. The fog effect disappears when there is a luminance
contrast all along the perimeter of the ellipse. An experiment is reported showing that the effect can be experienced in static
conditions only to a limited extent and mostly in the `dazzling' version, and that relative movement between the contours
of the figure and the shaded area is crucial to the occurrence of the effect, while the occurrence of a depth effect is not.

The relationship between self-reported received and perceived social support: A meta-analytic review
Social support is broad term encompassing a variety of constructs, including support perceptions (perceived support) and receipt
of supportive behaviors (received support). Of these constructs, only perceived support has been regarded as consistently
linked to health, and researchers have offered differing assessments of the strength of the received-perceived support relationship.
An overall estimate of the received-perceived support relationship would clearly further the dialogue on the relationship
between received and perceived support and thus assist in the theoretical development of the field. This study evaluated all
available studies using the Inventory of Socially Supportive Behaviors (ISSB; Barrera, Sandler, & Ramsey, 1981, American Journal of Community Psychology, 9, 435–447) and any measure of perceived social support. Using effect sizes from 23 studies, we found an average correlation
of r = .35, p < .001. Implications of this estimate for further development of models of social support as well as interventions to enhance
social support are discussed. 相似文献

The current study investigated the role of lifestyle as a significant factor related to the aggression and violence between cohabitating partners. Based on previous research, lifestyle was defined as a special reflection of socialization into society and working life, where different lifestyles should also be able to produce different patterns of socialization into people's roles as partners. It was found that gender and years of cohabitating were significantly related to Emotional aggression and Sexual violence; lifestyle patterns were associated with specific forms of violence. More specifically, the lifestyles of Pleasure & Elegance and the one of Culture-Intellectualism were found to promote Emotional aggression. Also, the lifestyle of Yuppies/Workaholic and that of Physical activities stimulated the appearance of Sexual violence between partners. Moreover, individuals with Tradition-Religiousness lifestyle were more likely to show lower levels of Physical & Sexual violence while the adherents of the Substance abuse lifestyle pattern appeared to have an inclination towards Physical & Sexual Violence. Finally, the occurrence of one form of violent behaviour was likely to be related to the other forms of violent behaviour. 相似文献

Being teased about one’s physical appearance in childhood has been found to have a strong impact on the way in which adolescent
and adult women perceive their bodies. Teasing is also strongly related to self-esteem in children. However, little is known
about the impact of teasing on the development of body image in childhood. Through a quantitative study of the experience
of being teased and body image satisfaction in a group of 431 primary aged children, we examined the prevalence, type and
impact of teasing on children’s perceived body image satisfaction. The results of our study indicated that many children,
especially those who are over or underweight experience being teased. This experience does have a negative impact on children’s
body image. This is especially significant for young girls and boys who are overweight. Underweight young boys also suffer
negatively from this experience. It is important for parents and others to understand that what may be perceived as friendly
banter with their children may not necessarily be innocuous. Further research exploring the concept and construct of teasing
in childhood is warranted. 相似文献

The SF-36 Health Survey and the WHO Quality of Life Index—BREF (WHOQOL-BREF) were used to study quality of life among women
who had experienced intimate partner violence (IPV). The aim was to determine how these instruments correlated with each other
and with physical and psychological IPV, in order to find the best instrument to use. IPV was measured using the Severity
of Violence against Women Scale (SVAWS) and the Psychological Maltreatment of Women Index (PMWI). A self-administrated questionnaire
was given to women able to understand Norwegian who were staying at a women’s shelter in Norway for more than 1 week. 87 of
212 women asked to participate completed the questionnaire. The physical acts of violence in SVAWS correlated significantly
(P<0.001) with both the general health and bodily pain dimensions in SF-36 and global overall health (OH) in WHOQOL-BREF. Most
correlations between WHOQOL-BREF and SF-36 were moderate. The WHOQOL-BREF domains explained 46% of the variance in OH and
40% of the variance in the global overall quality of life (OQOL). The SF-36 domains explained 66% of the variance in OH and
27% of OQOL. The mean WHOQOL-BREF and SF-36 scores were all low. The SF-36 correlated better with physical and psychological
IPV in this population than the WHOQOL-BREF. The significant correlations between the OH, general health and bodily pain domains
and acts of violence show the importance of including questions concerning bodily symptoms in determining the quality of life
in a population of abused women. 相似文献
