This article describes the Marriage and Family Therapy Practice Research Network (MFT‐PRN). The MFT‐PRN is designed to build a professional community based on practice‐informed research and research‐informed practice, increase the diversity of participants in MFT research, and unify researchers and clinicians. Clinics choose measures from a list that best represent their clinic needs. Clients' outcomes are assessed regularly, and therapists receive immediate graphical feedback on how clients are progressing or digressing. Data are pooled to create a large and diverse database, while improving client outcomes. We will discuss advantages of the MFT‐PRN for researchers, therapists, clients, and agencies, and provide one model that we hope will inform other collaborative clinical‐research models in the field of marriage and family therapy. Video Abstract is found in the online version of the article .  相似文献

There are societal concerns that looking at pornography has adverse consequences among those exposed. However, looking at sexually explicit material could have educative and relationship benefits. This article identifies factors associated with looking at pornography ever or within the past 12 months for men and women in Australia, and the extent to which reporting an “addiction” to pornography is associated with reported bad effects. Data from the Second Australian Study of Health and Relationships (ASHR2) were used: computer-assisted telephone interviews (CASIs) completed by a representative sample of 9,963 men and 10,131 women aged 16 to 69 years from all Australian states and territories, with an overall participation rate of 66%. Most men (84%) and half of the women (54%) had ever looked at pornographic material. Three-quarters of these men (76%) and more than one-third of these women (41%) had looked at pornographic material in the past year. Very few respondents reported that they were addicted to pornography (men 4%, women 1%), and of those who said they were addicted about half also reported that using pornography had had a bad effect on them. Looking at pornographic material appears to be reasonably common in Australia, with adverse effects reported by a small minority.  相似文献

Clinicians try to promote resilience by building an effective therapeutic relationship with their clients. Assertive Community Treatment (ACT) is an established approach for providing services to individuals with severe mental illness who have not fared well in the regular mental health system. This work underscores the importance of a resilient therapeutic relationship in preventing relapse and assuring adherence to therapeutic outcomes. Persistent psychiatric illness takes a toll on the resilience of the client, while the relationship work takes a toll on the resilience of the clinician. This article explores the concept of relational resilience between clinician and client as a dynamic process of shared success and failure, progress and regression through cycles of crisis, stabilization, relapse, and partial recovery. This is a qualitative study exploring how ACT clinicians promote and sustain resilience and is based on interviews with social workers, nurses, occupational and recreational therapists, coordinators, and psychiatrists.  相似文献

Mentoring is an extremely valuable activity for both individuals and organizations. Mentoring within organizations can develop and integrate employees into their corporate culture. Mentoring outside the mentees’ work groups or through professional development organizations can give broader perspective and support, especially in times of transition. But mentoring programs require tremendous effort to start, organize, and maintain. Few last more than two years. This article provides a structured approach to starting and sustaining a successful program. The steps include understanding an organization’s particular needs, learning from small pilot programs, following up with mentoring pairs during a committed formal mentoring period, and evaluating results from each program’s cycle to learn and grow the program. Supplementary materials for this article are available online.  相似文献

This study aimed to provide better understanding of intimacy and marriage, pregnancy, birth, and motherhood experiences of women with disability in Ethiopia. Qualitative, in-depth, and semi-structured interviews along with personal observations were used to explore the full experiences of participants, as told in their own words. The result of the interviews indicated that relationships and motherhood proved a very rewarding option for women with disabilities. They also expressed their need for intimacy regardless of society’s denial. Challenges identified include negative societal attitudes toward women with disabilities regarding relationship, pregnancy, and child-rearing. Accessibility of health centers in addition to the ignorance and negative attitudes of the physicians are also reported to be major challenges for the interviewees. This study highlights how rewarding the experience of motherhood was for the interviewees and also shows that women with disabilities face challenges at every step of their experiences, because of society’s prejudices toward disability.  相似文献

We extend the Weibull power series (WPS) class of distributions to the new class of extended Weibull power series (EWPS) class of distributions. The EWPS distributions are related to series and parallel systems with a random number of components, whereas the WPS distributions [Morais AL, Barreto-Souza W. A compound class of Weibull and power series distributions. Computational Statistics and Data Analysis. 2011;55:1410–1425] are related to series systems only. Unlike the WPS distributions, for which the Weibull is a limiting special case, the Weibull law is a particular case of the EWPS distributions. We prove that the distributions in this class are identifiable under a simple assumption. We also prove stochastic and hazard rate order results and highlight that the shapes of the EWPS distributions are markedly more flexible than the shapes of the WPS distributions. We define a regression model for the EWPS response random variable to model a scale parameter and its quantiles. We present the maximum likelihood estimator and prove its consistency and asymptotic normal distribution. Although series and parallel systems motivated the construction of this class, the EWPS distributions are suitable for modelling a wide range of positive data sets. To illustrate potential uses of this model, we apply it to a real data set on the tensile strength of coconut fibres and present a simple device for diagnostic purposes.  相似文献

This study investigates how men who have sex with men (MSM) use chat and dating sites based on theories of stigma-related offline behavior and online self-disclosure. We hypothesize that hidden MSM (those who self-label as heterosexual or who hide their same-sex sexual attraction from family, friends, acquaintances, or a female romantic partner) differ from open MSM in how they behave on gay chat and dating sites and in offline gay venues. Drawing on a survey of 12,002 MSM, we show that hidden MSM tend to mask their identity on gay chat and dating sites while avoiding offline gay venues. They also focus more strongly on online sexual activities (e.g., masturbating during online chats) when using gay chat and dating sites. However, they spend the same amount of time on these sites, and they use them to initiate offline sexual encounters as often and as fast as open MSM.  相似文献

ABSTRACT

Sixty-three percent of the total active tuberculosis cases in Canada were diagnosed among foreign-born individuals, representing 20% of the total population. The majority of these cases occur from the reactivation of tuberculosis infections acquired prior to immigration. A preventive policy consisting of screening and treating new immigrants for latent tuberculosis infection is evaluated on its efficacy for reducing the total number of tuberculosis cases, using tuberculosis incidence data between 1986 and 1995 from the Canadian tuberculosis reporting system. The most effective intervention is to screen for and treat latent tuberculosis infection among arriving immigrants from countries of birth with a tuberculosis incidence rate greater than 15 cases per 100,000.  相似文献

This article presents the results from an evaluation of a state-funded, prevention-based, pilot program called the Multi-Disciplinary Approach to Prevention Services that was designed to reduce the potential for child abuse and neglect. The program served 64 families of various races and ethnicities over two years. A quantitative pretest–posttest design was used to analyze existing program data related to client outcomes including parenting skills, parenting satisfaction, and the use of non-family resources to assist in improving skills and satisfaction. Means comparisons were used to assess the relationship between three standardized instruments (the Parenting Scale, the Eyberg Child Behavior Inventory and the Kansas Parental Satisfaction Scale). Findings indicated a statistically significant improvement regarding resource engagement by families, parenting behaviors and perceptions, and involvement with Child Protective Services. The results from this study offer insight into how to improve parenting behaviors and increase child protective factors for youth who are at risk of maltreatment. In addition, these findings contribute to strengthen the legitimacy of Weiner's Attribution Theory while providing the social work profession with additional data in areas of research targeting the intersection of financially viable prevention programs, family stability, parental education, resources engagement, and the reduction of child abuse and neglect. If additional research supports the efficacy of prevention programs such as MAPS, funding similar programs could lead to improved parenting and decreases in child maltreatment.  相似文献
