Studies show that the way an individual feels about bicycling – the degree to which they like bicycling – is an important predictor of whether or not they bicycle. But why do some people like bicycling and others don’t? This study explores factors that may influence an individual’s liking of bicycling, or more formally, their bicycling affect. We analyze a rich dataset from a cross-sectional survey of residents of six small U.S. cities using an ordered logit model. Results show that bicycling behavior has the strongest association with liking bicycling, with bicycling constraints following as the second most important factor. Individual cognitions, including perceptions and normative beliefs, also play important roles in predicting bicycling affect. Individual measures of the physical environment do not correlate with liking of bicycling, but the perception that biking to various destinations is safe does. Social environment factors influence liking of bicycling as well. Longitudinal research is needed to better understand the reciprocal relationship between bicycling affect and bicycling behavior as well as the effect over time of factors such as the physical environment. Nevertheless, this study offers an initial understanding of the potential determinants of bicycling affect that provides a starting point for further research as well as direction for the development of policies for getting more people on bicycles.  相似文献

Intolerance of uncertainty (IU) is characterized by negative beliefs and reactions to uncertainty. IU is present in emotional disorders and may be a mechanism of change in treatment . There are two components of IU, prospective and inhibitory IU, that may be differentially associated with outcome. The current study tested associations between pre- and post-treatment changes in the components of IU, symptoms of anxiety and depression, and treatment outcome in a large diagnostically heterogeneous partial hospital sample. Results suggested that social anxiety disorder was associated with greater pre-treatment prospective and inhibitory IU scores than those without the diagnosis. Results also showed that inhibitory IU predicted change in anxiety and depression symptoms and prospective IU and depression reductions predicted improvements in overall psychological health and psychological inflexibility. Only change in depression predicted improvement in interpersonal relationships throughout treatment. Clinical and theoretical implications of the findings are discussed.  相似文献

Telephone coaching is a treatment mode in Dialectical Behavior Therapy (DBT) that is designed to help clients generalize skills, prevent suicidal behaviors, and repair therapeutic ruptures. To date, phone coaching has received scant empirical investigation. The aims of this study were to (1) describe patterns in frequency of telephone calls and text messaging in DBT and (2) investigate whether demographic factors, baseline severity, suicidal behaviors, and therapeutic alliance are associated with phone and text frequency. Participants were 51 adults (35 treatment completers) with borderline personality disorder (BPD) in a six-month comprehensive DBT treatment program. Phone coaching frequency was documented by therapist weekly session notes. The average number of contacts per month was 2.55 (SD = 4.49). Four of the 35 treatment completers comprised 56% of the contacts. Having a recent history of suicidal behaviors, degree of severity at baseline, or the strength of the therapeutic alliance was not associated with phone coaching use. However, lower income was significantly associated with a higher frequency of phone coaching use. These preliminary results can help clinicians and administrators make informed decisions on how to better provide phone coaching and clarify the degree of effort involved in providing this service to clients with BPD.  相似文献

Studies on gene–environment interactions suggest that some individuals may be more susceptible to life adversities than others due to their genetic profile. This study assesses whether or not children with an extra X chromosome are more vulnerable to the negative impact of early life stress on cognitive functioning than typically-developing children.

A total of 50 children with an extra X chromosome and 103 non-clinical controls aged 9 to 18 years participated in the study. Cognitive functioning in domains of language, social cognition and executive functioning were assessed. Early life stress was measured with the Questionnaire of Life Events. High levels of early life stress were found to be associated with compromised executive functioning in the areas of mental flexibility and inhibitory control, irrespective of group membership. In contrast, the children with an extra X chromosome were found to be disproportionally vulnerable to deficits in social cognition on top of executive dysfunction, as compared to typically-developing children. Within the extra X group the number of negative life events is significantly correlated with more problems in inhibition, mental flexibility and social cognition. It is concluded that children with an extra X chromosome are vulnerable to adverse life events, with social cognition being particularly impacted in addition to the negative effects on executive functioning. The findings that developmental outcome is codependent on early environmental factors in genetically vulnerable children also underscores opportunities for training and support to positively influence the course of development.  相似文献

Children with 22q11.2 deletion syndrome (22q11DS; velo-cardio-facial-syndrome) are at risk for the developmental disorders, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). In this study, the relation between executive functioning (EF) and the severity of ADHD and ASD symptoms is examined, since EF is known to be important in relation to emotional and behavioral problems. The participants consist of 58 children (38 females) with a mean age of 13.5 years (SD 2.6). Standardized assessment was used to evaluate the severity of ASD and ADHD symptomatology. The major aspects of EF, i.e., cognitive flexibility, inhibition, sustained attention, distractibility, working memory and reaction speed, were evaluated. The profile of EF in 22q11DS was found to be characterized by weaker performance compared to the norms on all subdomains of EF. Poor cognitive flexibility and inhibition, as well as high distractibility, were found to be related to more severe ASD symptoms, while poor quality of sustained attention and high distractibility were found to be related to more severe ADHD symptoms. It is concluded that children with 22q11DS experience impairments in EF, and that the degree of impairment on specific EF subdomains is related to the severity of ASD and/or ADHD symptomatology. These results may help in defining the mediating role of neurocognitive dysfunctions in the development of social and behavioral problems in 22q11DS.  相似文献

Previous research has supported a three-factor division of the Behavior Rating Inventory of Executive Function (BRIEF) when dividing the parent form in 9 instead of 8 subscales. The present study investigated different factor models in the 8- and 9-scale division in both the parent and teacher form of the Norwegian BRIEF version. Confirmatory Factor Analyzes showed best fit for the three-factor model in a mixed healthy and clinical sample, indicating a distinction between Emotional and Behavioral Regulation. This division is in accordance with present knowledge of brain function and may increase the specificity of executive dysfunction in clinical groups.  相似文献

Social cognitive theory (Bandura, 1986, 1995, 1997) has figured prominently among social psychological approaches taken to the investigation of exercise behavior. The present study validated two measures of self-efficacy (scheduling and task) through confirmatory factor analytic procedures. In a separate study, the resultant factors were then used as independent variables in the prediction of exercise behavior and behavioral intention in a structural equation model. Task self-efficacy was found to be more related to behavioral intention than scheduling self-efficacy. Scheduling self-efficacy was found to be more related to behavior than task self-efficacy or behavioral intention. Results support different types and motivational functions of self-efficacy for exercise intentions and behavior.  相似文献

Empirical research has identified two distinct item clusters used to measure perceived behavioral control (PBC) labeled self-efficacy and controllability. Self-efficacy has been reported as the superior predictor of intention in all research efforts with these PBC factors. However, we argue that the conception of these item clusters originates from backward theorizing and hypothesize that controllability items are better indicators of the originally conceived PBC construct, while self-efficacy taps the measurement domains of both PBC and intention. Therefore, the purpose of this study was to investigate factor distinction with PBC and intention items across disparate samples of 302 undergraduate students and 267 cancer survivors in the exercise domain. Results found the only model with acceptable fit across populations was that of controllability and intention ( h 2 (8) = 6.91, p = 0.55; RMSEA = 0.00; CFI = 1.00 for undergraduates and h 2 (8) = 26.51, p <0.01; RMSEA = 0.09; CFI = 0.97 for cancer survivors) supporting our hypothesis that the controllability concept, but not the self-efficacy factor, has a clean measurement distinction from intention. Further, self-efficacy items showed factor complexity between PBC and intention across both samples, suggesting that self-efficacy may have been reported as superior to controllability in predicting intention due to measurement redundancy rather than meaningful causal influence.  相似文献

Alcohol misuse and sleep disorders are highly comorbid, prevalent among service members and their romantic partners, and affected by relationship interdependence. As most military health research focuses on either service members or their spouses, the current study examined dyadic effects of alcohol use on sleep cycle duration in dating and married military couples (= 149 dyads), using data from the National Longitudinal Study of Adolescent Health. Person-level results from a series of multilevel path models showed partial support for our focal hypothesis implicating high alcohol use in shortened average sleep duration for the service members and their romantic partners. Specifically, partners of service members who drank more regularly had shorter average sleep durations, as did female service members who drank more alcohol per drinking occasion. At the couple-level, a partner effect indicated that service members’ lower depressive symptoms were associated with their partner’s shorter average sleep durations. In addition, when service members reported relatively high alcohol-related problems, their partner tended to have a shorter average sleep duration. In contrast, when service members’ partners reported relatively high alcohol-related problems, they had a longer average sleep duration. This suggests the consequences of problematic alcohol use for service members’ partners depended on each dyad member’s drinking patterns. Taken together, these findings underscore the importance of viewing military couples as a dyadic unit in research studies and clinical interventions.  相似文献

The purpose of this article is to develop a framework for the origin of foresight. Following a review of arguments for foresight as genetically inherited versus environmentally acquired, the understanding of foresight is expanded through a behaviorist perspective and through an evolutionary perspective. The framework established makes it possible to deploy evolutionary logic to explain foresight as well as to enhance our understanding of foresight, both on individual (e.g., managerial) and aggregated (e.g., organizational) levels.  相似文献
