This qualitative study examined preadolescent boys’ and girls’ body ideals, and peer and media factors that shape these ideals. Sixty-eight children aged 8–10 participated in semi-structured interviews: 19 boys and 17 girls in individual interviews and 16 boys and 16 girls in eight group interviews. Techniques from grounded theory were used to analyze the data. Findings demonstrated that fitness was an important element of boys’ and girls’ body ideals. For boys the emphasis was on sport, and this was promoted by their peer interactions and the sportsmen they admired. For girls the focus was on looking good, and this was reinforced by their peer conversations, and the actresses and singers they admired. Focus groups further highlighted how peers both reinforced media messages, yet also helped children critique media messages. Implications are discussed for prevention programs that need to be specifically tailored for boys and girls.  相似文献

Developmental studies of mental disorders based on epidemiological data are often based on cross-sectional retrospective surveys. Under such designs, observations are right-censored, causing underestimation of lifetime prevalences and correlations, and inducing bias in latent trait models on the observations. In this paper we propose a Partial Likelihood (PL) method to estimate unbiased IRT models of lifetime predisposition to develop a certain outcome. A two-step estimation procedure corrects the IRT likelihood of outcome appearance with a function depending on (a) projected outcome frequencies at the end of the risk period, and (b) outcome censoring status at the time of the observation. Simulation results showed that the PL method yielded good recovery of true frequencies and intercepts. Slopes were best estimated when events were sufficiently correlated. When PL is applied to lifetime mental health disorders (assessed in the ESEMeD project surveys), estimated univariate prevalences were, on average, 1.4 times above raw estimates, and 2.06 higher in the case of bivariate prevalences.  相似文献

We sought to determine if the asymmetrical tonic neck reflex influences the accuracy of self-selected arm positioning without vision and to ascertain if such accuracy is influenced by a pre-contraction of the prime movers. Participants reproduced an arm position using their abductors with the head in midline, rotated towards and away from the arm. Arm movements were made with and without a pre-contraction of the abductors. Twenty participants performed eight trials in each of the six different conditions. Compared to the midline position, participants undershot the reference position with the head turned away and overshot the position with the head rotated towards the arm. A pre-contraction caused undershooting regardless of head position. Results suggest that head position and pre-contraction may have significant and independent effects on arm positioning.  相似文献

Although income and inequality (objective measures of deprivation and the distribution of income within a defined area, respectively) predict people's self‐appraisals, the psychological mechanisms underlying these relationships are largely unknown. We address this oversight by predicting that feeling individually deprived (individual‐based relative deprivation [IRD])—a self‐focused appraisal—mediates the relationship between these two objective measures and self‐esteem. Conversely, believing that one's group is deprived (group‐based relative deprivation [GRD])—a group‐focused appraisal—mediates the relationship between these two objective measures and ethnic identity centrality. We examined these predictions in a national sample of New Zealand adults (N = 6349). As expected, income negatively correlated with IRD and GRD; in turn, IRD negatively correlated with self‐esteem, and GRD positively correlated with ethnic identity centrality. Moreover, after accounting for between‐level variability in income, neighbourhood‐level inequality had indirect effects on self‐esteem and ethnic identity centrality through IRD and GRD, respectively. Thus, income and inequality independently predicted self‐esteem and strength of ingroup identification through distinct mechanisms. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Reflective practice is recognised as an integral part of being a highly skilled and successful health care professional. Many benefits have been identified from being a reflective practitioner including the opportunity for critical thinking, growing self-awareness and supporting individual resilience. There is a growing body of literature recognising the negative emotional impact that caring for children with cancer and blood disorders can have on health professionals. Currently there is an emerging interest in a more strengths-based approach focused on maintaining staff wellbeing. Resilience has been suggested as a framework for coping and maintaining wellbeing in areas, like children’s oncology and has been used as a term to describe the ‘surviving’ health professional. This paper explores the first author’s (GA) experiences of being a children’s oncology nurse and paediatric palliative care nurse specialist in the context of existing empirical and theoretical literature, with a particular focus on how GA developed resilience. Reflective examples of practice are used within the context of themes identified from a recent literature review exploring how resilience is defined within empirical literature.  相似文献

Cannabis (marijuana) has undergone a normalizing process as indicated by high use rates, social tolerance, and broader cultural acceptance of its use in many countries. Users also maintain access through extended friendship networks that facilitate the cultural diffusion of the practice. The social nature of supply is herein theorized in terms of Goffman’s understanding of activities that function to preserve a sense of normalcy as a collective achievement enabling predictable constructions of reality. Based on in-depth interviews with undergraduate students, we explore how social networks of supply—characterized by casual access, reciprocity, and sharing—contribute to shared meanings about using marijuana as an unremarkable or “normal” thing to do.  相似文献

Objective: Partners of acute coronary syndrome (ACS) patients are at risk of experiencing long-term distress and the purpose of this study was to identify its predictors.

Design: Using an observational design, 80 partners of ACS patients completed validated questionnaires at three time points. The predictor variables, marital satisfaction and optimism were assessed three weeks after patient hospital discharge (T1). The outcomes, depressive symptoms and physical health status (from a quality of life scale) were measured 6 (T2) and 12 (T3) months post-discharge, and scores were combined to indicate the long-term response.

Main outcome measures: Depressive symptoms and physical health status.

Results: Partner depressive symptoms increased and physical health status deteriorated over the months following the patients’ ACS. After controlling for demographics, clinical severity of ACS and T1 levels of the outcome variable, partners’ long-term depressive symptoms were predicted by poor marital satisfaction and low optimism at T1, and poor physical health status was predicted by low T1 optimism.

Conclusion: Psychosocial factors are predictors of long-term distress for ACS partners. Partners in an unhappy marriage or with low optimism after ACS are at an increased risk of depression and low physical health status, and should be the target of additional support.  相似文献

This study examined patients’ illness representations assessed shortly after an acute coronary syndrome (ACS) as predictors of posttraumatic stress symptoms six months later. Illness representations were assessed in ACS patients using standard measures at a home visit three weeks after discharge from hospital. Posttraumatic stress symptoms were assessed at the same time, and again six months later. Patients were aged 61 years on average, the majority being men (89.8%) of white European decent (89%). Greater posttraumatic symptoms at six months were associated with beliefs that the illness would last a long time (timeline), that it had an unpredictable time course (timeline – cyclical), greater consequences, less personal and treatment control, poorer illness coherence and stronger negative emotional representations (emotional upset relating to the illness; p?<?0.05). In multiple regression analyses, controlling for demographic, clinical and psychological factors (age, gender, ethnicity, social deprivation, ACS severity, negative affectivity and cardiac symptom recurrence), more intense emotional representations (β?=?0.146, p?=?0.041) and reduced illness coherence (β?=??0.133, p?=?0.029), emerged as independent predictors of posttraumatic symptom severity at six months. There was a near significant effect for personal control (β?=??0.113, p?=?0.058). These results demonstrate the importance of illness representations of ACS in predicting longer-term posttraumatic stress symptoms.  相似文献

The second to fourth digit ratio (2D:4D) indicates androgen exposure during early development. Numerous methods are used in the assessment of 2D:4D, however, some are not reliable enough and others are difficult to perform in large epidemiological studies. We assessed the reliability of 2D:4D using a direct method with a caliper, and compared it with a computer-assisted analysis on scanned images. Both methods were moderately correlated, but the scan method produced slightly lower 2D:4D. The main source of variation was differences between subjects (real variation). Reliability was higher among men and among younger participants. All reliability coefficients were higher than 0.8 when three repeated measurements were averaged. Our results suggest that reliability is influenced by participants’ characteristics. Digit ratios determined directly with calipers are reliable when repeated measurements are averaged.  相似文献

Face construction by selecting individual facial features rarely produces recognisable images. We have been developing a system called EvoFIT that works by the repeated selection and breeding of complete faces. Here, we explored two techniques. The first blurred the external parts of the face, to help users focus on the important central facial region. The second, manipulated an evolved face using psychologically‐useful ‘holistic’ scales: age, masculinity, honesty, etc. Using face construction procedures that mirrored police work, a large benefit emerged for the holistic scales; the benefit of blurring accumulated over the construction process. Performance was best using both techniques: EvoFITs were correctly named 24.5% on average compared to 4.2% for faces constructed using a typical ‘feature’ system. It is now possible, therefore, to evolve a fairly recognisable composite from a 2 day memory of a face, the norm for real witnesses. A plausible model to account for the findings is introduced.
