ObjectivesThe effect of physical inactivity on mental health risk is well established; however, less is known about about how psychological distress might deter participation in physical activity. Guided by advancements in the treatment of longitudinal data, the aim of this study was to examine patterns and predictors of change in moderate-to-vigorous physical activity (MVPA) and psychological distress (e.g., feeling nervous, worthless).Design methodAustralian adults (4944 females, Mage = 34.63 years ±5.34; 4322 males, Mage = 37.51 years ±6.14) provided baseline data as part of the Longitudinal Study of Australian Children (LSAC) and were followed for measurements every two years for 10 years.ResultsLatent change score analyses revealed support for a reciprocal effects model, whereby change in MVPA and psychological distress occurred as a function of individuals’ prior levels of, and/or prior change in these variables.ConclusionsThis investigation is the first to document that changes in MVPA and psychological distress are coupled temporally. Notably, we observed that individuals’ distress levels at a given time point predicted subsequent change on both MVPA and distress; a finding which provides novel and important insight into how adults’ activity levels and psychological distress fluctuate relative to one another. 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

Maintaining loss of weight beyond an initial 6–9 months remains problematic, with research indicating little recent progress. A poor understanding of how and when prior weight loss, behavioral changes, and psychosocial predictors are associated with long-term weight changes persists. To better-inform behavioral treatments for long-term success with weight loss, women with obesity (N = 86; Mage = 48.6 years) volunteered for research incorporating community-based weight-management treatments. They were assessed at months 6, 12, and 24 on theory-based psychosocial and behavioral factors, and over 24 months on weight. Considering the included times and temporal ranges, it was found that change in weight from month 6–24 was the strongest predictor of 24-month weight change, and physical activity and fruit/vegetable intake at month 24 best predicted that change in weight. Self-regulation, self-efficacy, and mood at month 24 best predicted both physical activity and fruit/vegetable intake at month 24, with body satisfaction also a significant predictor of physical activity. From these data, mediation analyses found that the predictions of long-term weight loss by scores of self-regulation, self-efficacy, body satisfaction, and mood at month 24 were significantly mediated by fruit/vegetable intake and physical activity in separate equations. Findings indicated both psychosocial and behavioral targets, and timing for those targets, most indicative of long-term success with weight loss. 相似文献

Autonomic and affective responses to two different stress tasks were measured in 45 males and 74 females, categorized as repressive, true low-anxious, true high-anxious, and defensive high-anxious. Electrodermal activity (EDA) was used as a measure of sympathetic activity and the high frequency (HF) spectral component of heart rate variability as a measure of parasympathetic activity. Contrary to our predictions, reactivity of repressors did not differ from the reactivity of true low-anxious participants. The results draw attention to previous inconsistent findings within the literature on repressive coping style and autonomic nervous system dysregulation. It is suggested that future research could benefit from the use of more consistent operationalizations of the repressive coping construct and from comparing alternative measures of repressive coping within the same study. 相似文献

A field-oriented interpretation of Whiteheadian societies of actual occasions, when used to explain the notion of "strong supervenience" as applied to the mind-brain problem, allows one to claim that not only higher-level properties such as consciousness but even higher-level entities such as the mind or soul are emergent from lower-level systems of neuronal interaction. Moreover, it also explains the preexistence of God to the world and Christian belief in eternal life with the triune God in a way that is impossible within the limits of a theory of strong supervenience. 相似文献

In the present study the effects of a wide range of doses of the dopamine release inhibitor CGS 10746B were evaluated in spontaneous activity and in aggressive behaviour using the paradigm of isolation‐induced aggression. The two higher doses (8 and 16 mg/kg) produced a decrease in spontaneous motor activity. Antiaggressive effects were observed after administration of doses from 4 mg/kg upwards. At this dose, CGS 10746B diminished threat and attack, and although an increase in immobility was observed, no impairment of other motor behaviours was presented. With higher doses, aggression was practically abolished but with a concomitant effect on many other behaviours. When animals were separated depending on their latency of attack, those that showed a long attack latency (LAL) presented a stronger response to 4 mg/kg than those that had a short attack latency (SAL), which were not affected in their aggression by this dose. We can conclude that presynaptic dopamine function is necessary for the normal expression of aggressive behaviours, since CGS 10746B reduces aggression at doses that do not affect spontaneous motor activity.

As the standard of living improves and the number of choices expands, consumer behavior shifts from meeting needs to realizing the specific life values of each consumer. A structural analysis of life values was performed to increase understanding of consumer behavior as a whole, so that effective marketing strategies can be prepared. The structural analysis of life values was conducted by plotting daily activities in an evaluation space, which was defined by "necessity,""attractiveness," and "ease of achievement," and also by factor analysis of these daily activities. Using this method, we measured the structure of the daily activities of Japanese consumers, and then examined the value structure of time-consuming activities, which our research suggests will be considered highly attractive in the future. Based on the results of the surveys, we discuss the development of the market for highly attractive activities and products. However, an improvement in life infrastructure is a prerequisite to realizing a market for highly attractive activities and products. 相似文献

Marital Conflict and Risk for Child Maladjustment over Time: Skin Conductance Level Reactivity as a Vulnerability Factor 总被引:4,自引:0,他引:4
Skin conductance level reactivity (SCLR) was examined as a longitudinal mediator and moderator of relations between parental marital conflict and psychopathology among children and young adolescents. Participants were 157 boys and girls (M age at T1 = 9.31 years; SD = 1.97); there was a 2-year lag between T1 and T2 assessments. At T1, participants' SCLR was assessed in response to lab challenges. Parents completed measures of aggressive marital conflict and child adjustment at T1 and T2. Supportive of moderation effects, T1 marital conflict interacted with T1 SCLR and gender in the prediction of changes in maladjustment. The link between marital conflict and increased internalizing and externalizing symptoms was stronger for girls with higher SCLR than girls with lower SCLR. Marital conflict predicted increased externalizing behaviors for boys with lower SCLR but not higher SCLR, although levels of externalizing behaviors were similar among boys with lower and higher SCLR especially at higher levels of marital conflict. Findings build on the literature by illustrating the importance of examinations of both family risk and youth biological vulnerability for the prediction of psychopathology. 相似文献
