The authors examined factors influencing the return rates for attempting to collect active parental consent forms from 21,123 students in the 7th through 10th grades in 41 middle and high schools. Overall return rates from middle schools were higher than from high schools. Schools that offered high levels of staff support for collecting consent forms had higher return rates. Procedures where the consent form was attached to a school form that parents had to complete and return to the school yielded the highest return rate. Implications for how researchers can obtain a high parent consent form return rate are discussed.  相似文献

Research has consistently documented black-white differences in rates of voluntary psychiatric treatment that cannot be reduced entirely to differences in either need or access. A variety of explanations have been offered for the gap that remains, but the empirical testing of alternative propositions has thus far been minimal. Using the 1998 General Social Survey's Pressing Issues in Health and Medical Care module (n = 1,387), I find consistent and substantial black-white differences in a variety of beliefs about psychiatric medications, one of the most common treatments for mental illness, and the predisposition to use them. Specifically, blacks express less willingness to use psychiatric medications themselves or to administer them to a child for whom they are responsible. Neither socioeconomic status, knowledge, religious involvement, nor trust in medicine appears to explain this reluctance. Rather, it stems almost entirely from blacks' beliefs about psychiatric medications' efficacy and side-effects. The results indicate, first, that researchers should not assume that African Americans will use psychiatric medications at rates similar to whites if offered equal access. Second, the results indicate that blacks' skepticism of psychiatric medications may be rooted in specific beliefs about psychiatric medications, rather than general ideologies about medical practice. Health beliefs about psychiatric treatment, therefore, will continue to play an important role in understanding race differences in the use of psychiatric medications.  相似文献

Expectancy theory has been criticized for its omission of normative, habitual, and other motivational elements. This paper describes the sources and features of an integrative motivational model from the field of preventive health care that combines expectancy/valence factors with habitual, normative, and conative motivational elements. The model is viewed as having implications for work motivation as well.  相似文献

Through dialogue and reflexivity, feminist researchers aim to create knowledge that is emergent from people in relationship with one another. Reflexivity is a process whereby researchers place themselves and their practices under scrutiny, acknowledging the ethical dilemmas that permeate the research process and impinge on the creation of knowledge. Guided by these tenets, we analyzed the relations among our research practices, our participants, and ourselves to understand and reduce the ethical tensions we encountered in a multimethod research project designed to investigate work and family processes. Our reflective efforts underscore both the active nature of research participants and the importance of the sociopolitical contexts within and around the research process. We make suggestions for more ethical research.  相似文献

Mahjong is a popular gambling game played in Chinese communities all over the world (Papineau, China Perspect 28:29–42, 2000) and is sometimes referred to as ‘国赌’ (guodu, the Chinese national gambling game) or ‘修长城’ (xiu changcheng, repairing the Great Wall). Exploratory studies using snowball sampling conducted by Zheng et al. (J Psychol Chin Soc 9(2):241–262, 2008) indicated that Mahjong is not only a popular pastime within the Sydney Chinese community but also problematic for around 3% of players. The current study aimed to extend earlier studies by estimating the prevalence of Mahjong problem gambling in a random sample of Sydney Chinese community members. In addition, due to first-hand gambling experience of the first author with superstitious Mahjong players, the study also investigated the role of superstitious beliefs in Mahjong gambling. The current study involved a series of self-report questionnaires administered to 469 randomly selected Chinese Australians in Sydney. The problem gambling rate, assessed by the Canadian Problem Gambling Index (CPGI), was 3.8%, with Chinese males and older Chinese prominent. Superstitious beliefs were found to play a part in the maintenance of Mahjong gambling behaviour. Information stemming from the current study has helped gain insight into culturally specific forms of gambling, and to identify correlates of problem gamblers. Funding bodies and counselling services should be aware of the existence of this form of gambling, and should devise appropriate treatment plans for Mahjong problem gamblers.  相似文献

This paper proposes Bayesian nonparametric mixing for some well-known and popular models. The distribution of the observations is assumed to contain an unknown mixed effects term which includes a fixed effects term, a function of the observed covariates, and an additive or multiplicative random effects term. Typically these random effects are assumed to be independent of the observed covariates and independent and identically distributed from a distribution from some known parametric family. This assumption may be suspect if either there is interaction between observed covariates and unobserved covariates or the fixed effects predictor of observed covariates is misspecified. Another cause for concern might be simply that the covariates affect more than just the location of the mixed effects distribution. As a consequence the distribution of the random effects could be highly irregular in modality and skewness leaving parametric families unable to model the distribution adequately. This paper therefore proposes a Bayesian nonparametric prior for the random effects to capture possible deviances in modality and skewness and to explore the observed covariates' effect on the distribution of the mixed effects.  相似文献

Stress, confusion, and a sense of loss were inevitable during the hospital relocation, especially given the large number of clients, ward communities, and staff needed to move and adjust to change. Despite the fact that the change was perceived as a positive and progressive step in psychiatric-mental health care in Grenada, there were many obstacles and much resistance to overcome. As expected, staff's and clients' fears centered around themes of impending loss and abandonment. An understanding of the transition process, along with the availability of experienced hospital staff for support and guidance, greatly aided the relocation process. Relocation still presented problems and Mt. Gay Hospital continues to struggle to carry out the lasting and beneficial changes that will best promote a therapeutic and culturally sensitive client/staff environment. Despite the fact that the hospital relocation was not entirely self-determined, but partially imposed by political circumstances, a positive resolution of the crisis occurred. The crisis brought about the change that, in this circumstance, is seen as synonymous with growth. It acted as a catalyst to bring about help from unexpected and much needed sources (U.S.A.I.D./Project Hope), which may not have otherwise been available to facilitate such a change. Richmond Hill Mental Hospital took control and advantage of a crisis situation and made it serve its immediate and pressing need for a new psychiatric hospital.  相似文献

Implementation of a full Bayesian non-parametric analysis involving neutral to the right processes (apart from the special case of the Dirichlet process) has been difficult for two reasons: first, the posterior distributions are complex and therefore only Bayes estimates (posterior expectations) have previously been presented; secondly, it is difficult to obtain an interpretation for the parameters of a neutral to the right process. In this paper we extend Ferguson & Phadia (1979) by presenting a general method for specifying the prior mean and variance of a neutral to the right process, providing the interpretation of the parameters. Additionally, we provide the basis for a full Bayesian analysis, via simulation, from the posterior process using a hybrid of new algorithms that is applicable to a large class of neutral to the right processes (Ferguson & Phadia only provide posterior means). The ideas are exemplified through illustrative analyses.  相似文献
