This study tested potential mediators of a school-based skin cancer prevention intervention for middle school children (6th-8th grades; N = 1,788). Ten variables were tested on 4 criteria to establish mediation, including (a) intervention related to outcome, (b) intervention related to mediators, (c) mediators related to outcome, and (d) mediated effect statistically significant. Sun-safe behaviors (e.g., sunscreen use) and potential mediators were measured with a self-report questionnaire. All criteria were met for Barriers--Sunscreen, Perceived Self-Efficacy, and Knowledge when the mediators were tested separately. In multiple mediator analyses, barriers to sunscreen use and self-efficacy satisfied Criteria 1-3 but were not statistically significant (Criterion 4). Barriers to sunscreen use, perceived self-efficacy for sun-safe behavior, and knowledge may serve as mediators. 相似文献

Although 4-month-olds perceive continuity of an object's trajectory through occlusion, little is known about the information specifying an occluding surface at this age. We investigated this in 3 experiments involving 84 participants. Testing the claim that 5-month-olds are unable to perceive the Kanizsa figure as an occluding surface (Csibra, 2001), we demonstrated that 4-month-olds perceived trajectory continuity behind this figure providing its horizontal extent was small. We demonstrated that the presence of visible occluding edges or occlusion of background was insufficient to specify an occluding surface but that their combination was sufficient. Thus, beyond object deletion and accretion, both visible occluding edges and occlusion of background are necessary for perception of occluding surfaces at this age. 相似文献

We investigated oculomotor anticipations in 4-month-old infants as they viewed center-occluded object trajectories. In two experiments, we examined performance in two-dimensional (2D) and three-dimensional (3D) dynamic occlusion displays and in an additional 3D condition with a smiley face as the moving target stimulus. Rates of anticipatory eye movements were not facilitated by 3D displays or by the (presumably) more salient smiley face relative to the 2D condition. However, latencies of anticipations were reduced, implying that 3D visual information may have supported formation of more robust mental representations of the moving object. Results are interpreted in a context of perceptual constraints on developing cognitive capacities during early infancy. 相似文献

Informed by a trans‐theoretical model of the therapeutic alliance in conjoint family therapy, this exploratory study was the initial stage in a task analysis of critical shifts in adolescent engagement. Specifically, we compared sessions in which a resistant adolescent either did or did not shift from negative to positive engagement during the session. Two successful and two unsuccessful change events were selected from an archival data set based on SOFTA ratings of the therapeutic alliance. The results suggested that one parent element (support) and five therapist elements (structuring therapeutic conversations, fostering autonomy, building systemic awareness, rolling with resistance and understanding the adolescent's subjective experience) seemed critical for successfully facilitating adolescent engagement. The qualitative results were informed by the adolescent's self‐reported target complaints pretreatment, which suggested varying reasons for the teenagers’ active or passive disengagement. Implications for practice and recommendations for future research are offered to continue this line of inquiry. 相似文献

Objectives
The purpose of this study was to examine the antecedents, specificity, and ceiling effects of golfers’ implicit theories of sport ability.Design
The present study employs a qualitative research design. A constructivist grounded theory methodology was adopted.Method
Participants (N = 8) were asked to describe their conceptions of golf ability. All responses were recorded, transcribed, and the data were analyzed through a series of iterations, which led to the identification of three dimensions that constitute golfers’ beliefs about ability.Results
The three dimensions were: acquirable ability, stable ability, and developing natural attributes. Categories within these dimensions offer initial evidence for the role of social agents and the inherent culture of golf in shaping co-existing beliefs in relation to sport ability. Beliefs with regards to ceiling effects of ability are reported, with one theme proposing a ceiling to sport ability, and a contrasting category exemplifying the belief that there is always room for improvement.Conclusions
The present study contributes to the field by offering initial evidence for the antecedents, specificity, and ceiling effects of golfers’ conceptions of their sport ability. Implications, both theoretical in terms of future research, and practical with regards to practitioners’ role in educating athletes and cultivating an environment conducive to the perception that sport ability is acquirable, are offered. 相似文献906.
Understanding precursors to distress and emotional well-being (EWB) experienced in anticipation of radiotherapy would facilitate the ability to intervene with this emotional upset (i.e. higher distress, lower EWB). Thus, this study tested an expectancy-based model for explaining emotional upset in breast cancer patients prior to radiotherapy. Women affected by breast cancer (N?=?106) were recruited and participants completed questionnaires prior to commencing radiotherapy. Structural equation modelling was used to test a cross-sectional model, which assessed the ability of dispositional optimism (Life Orientation Test-Revised - two factors), response expectancies (Visual Analog Scale items), medical (type of surgery, cancer stage and chemotherapy history) and demographic (age, race, ethnicity, education and marital status) variables to predict both EWB (Functional Assessment of Chronic Illness Therapy - Emotional Well-being Subscale) and distress (Profile of Mood States - short version). The model represented a good fit to the data accounting for 65% of the variance in EWB and 69% in distress. Significant predictors of emotional upset were pessimism, response expectancies, Latina ethnicity, cancer stage and having had a mastectomy. These variables explained a large portion of emotional upset experienced prior to radiotherapy for breast cancer and are important to consider when aiming to reduce distress and improve EWB in this context. 相似文献

Employment tests, once primarily focused on screening external applicants, are increasingly used for decisions involving internal candidates (e.g., promotions or lateral transfers). The current study examines differences between internal and external candidates in reactions to an online selection test. Results indicate that internal candidates perceived a general lack of advance information regarding the assessment. However, they were considerably more likely to recommend the organization to others as compared with external candidates. Candidate status also moderated several reactions–outcomes relationships. Results are discussed in terms of their implications for organizations and directions for future research on internal candidate reactions are proposed. 相似文献

Identifying risk factors for Alzheimer's disease, such as carrying the APOE-4 allele, and understanding their contributions to disease pathophysiology or clinical presentation is critical for establishing and improving diagnostic and therapeutic strategies. A first-degree family history of Alzheimer's disease represents a composite risk factor, which reflects the influence of known and unknown susceptibility genes and perhaps non-genetic risks. There is emerging evidence that investigating family history risk associated effects may contribute to advances in Alzheimer's disease research and ultimately clinical practice. 相似文献

Cancer-related fatigue (CRF) is a common and distressing side-effect of cancer treatment. The present study developed a brief version of the Illness Perception Questionnaire (IPQ) for assessing patients' representations of CRF. Cancer patients and survivors (n?=?155) completed a revised version of the IPQ as well as measures of fatigue severity at two different time-points. Confirmatory factor analysis at both Time 1 and 2 showed that the seven-factor solution based on the Self-Regulation Model fit the data adequately and factorial invariance over the two time-points was supported. The resulting subscales exhibited good internal consistency and test-retest reliability. The adapted version of the IPQ shows promise for the assessment of patient perceptions regarding CRF. The scale may be able to be used clinically to identify if patients have inaccurate or unhelpful representations of CRF and to help tailor interventions for persistent fatigue in cancer survivors. 相似文献

This study investigates body esteem factors (weight-esteem and appearance-esteem) as mediators of the relationship between ‘internalization of the ideal body figure’ and disordered eating behaviors (restrained, emotional and external eating) in a community sample of adolescent males (n = 810) and females (n = 1137) from the Ontario Research on Eating and Adolescent Lifestyles (REAL) study. Mediation models were examined using a bootstrapping approach to test indirect effects and indirect contrasts. In males, weight-esteem partially mediated the relationship between muscular ideal and restrained eating; appearance-esteem partially mediated effects in the emotional and external eating regressions. In females, both weight-esteem and appearance-esteem partially mediated the relationship between thin ideal and all three forms of disordered eating; weight-esteem was a stronger mediator for restrained eating, and appearance-esteem a stronger mediator for emotional and external eating. Body esteem is important to consider for prevention and treatment of disordered eating in both genders. 相似文献
