The effectiveness of intense specialised multi-family therapy (ISMFT) for 111 multi-stressed families, and the therapeutic alliance as a possible predictor of outcome, were examined. A repeated measures design was used, where changes in all ISMFT phases (preparation, multi-family therapy and follow-up) were assessed and compared for both mothers and fathers. Evidence was found for improved family functioning after the therapy period, which was maintained at 3 months follow-up, although the multi-stressed families still functioned in the problematic range. The therapy did however not decrease parenting stress, or did so only temporarily. Observations of the therapeutic alliance with the System for Observing Family Therapy Alliances (SOFTA) scales indicated that high therapist engagement was related to positive therapy outcomes, both at the start of therapy and later. High family engagement also predicted therapy effectiveness, but only at the start of therapy. The present study shows that solution-focused multi-family therapy at least seems to provide the first step in alleviating problems in multi-stressed families. 相似文献

Previous research has evaluated the effects of prompt rates on the rate of communicative behavior. More recent research has suggested that dense prompting can result in communicative behavior that is more resistant to change. However, existing research has not considered the impact that higher response rates had on reinforcement rate, a variable known to impact response persistence. The current study systematically replicated previous research by evaluating communicative responding in contexts associated with dense- and lean-prompt schedules and extended existing research by (a) holding reinforcement rates similar across the two prompting schedules (lean and dense), and (b) evaluating the persistence of communicative responding in the contexts associated with each prompting schedule. The results for Experiment 1 clearly replicated and extended previous research. The results for Experiment 2 were equivocal and suggested that previous reinforcement history and response class size impacted outcomes. 相似文献

Social identity approach (SIA) research shows that community members often work together to support survivors of collective victimization and rectify social injustices. However, complexities arise when community members have been involved in perpetrating these injustices. While many communities are unaware of their role in fostering victimization, others actively deny their role and responsibility to restore justice. We explore these processes by investigating experiences of community violence and collective justice-seeking among Albanian survivors of dictatorial crimes. Survivors (N = 27) were interviewed, and data were analysed using theoretical thematic analysis guided by the SIA. The analysis reveals the diverse ways communities can become harmful ‘Social Curses’. First, communities in their various forms became effective perpetrators of fear and control (e.g., exclusion and/or withholding ingroup privileges) during the dictatorship because of the close relationship between communities and their members. Second, communities caused harm by refusing to accept responsibility for the crimes, and by undermining attempts at collective action to address injustices. This lack of collective accountability also fosters survivors' feelings of exclusion and undermines their hope for systematic change. Implications for SIA processes relating to health/wellbeing (both Social Cure and Curse) are discussed. We also discuss implications for understanding collective action and victimhood. 相似文献

Interruption and redirection (IR) procedures involve systematically disrupting an undesirable behavior and prompting an individual to engage in an alternative behavior. These procedures have been frequently assessed for reducing repetitive behaviors for autistic individuals. The primary purpose of this review was to assess IR interventions to determine whether outcomes vary according to intervention characteristics, dependent variable types, design quality, or publication status. A secondary purpose was to assess the extent to which generalization and maintenance outcomes were measured and whether characteristics of these conditions were related to outcomes. IR interventions were moderately successful for reducing repetitive behaviors but less effective for improving corollary variables such as appropriate vocalizations and functional engagement. Generalization and maintenance outcomes, when measured, were poor. Results indicate the need for alternative or augmentative procedures that focus on engagement in meaningful interactions and activities. 相似文献

When I say “I know Sarah,” or “I know Berlin,” what sort of knowledge am I claiming? Such knowledge of a particular is, I claim, not reducible to either propositional knowledge-that or to traditional physical know-how. Mere, bare knowledge by acquaintance also does not capture the kind of knowledge being claimed here. Using knowledge of a place as my central example, I argue that this kind of knowledge-of, or “objectual knowledge” as it is sometimes called, is of a distinctive epistemological sort. It is a genre of inherently first-personal aesthetic knowledge, but it also, like know-how, involves active skill. I end by exploring a couple of classic problems in aesthetic epistemology, applied to the case of knowledge-of as active aesthetic knowledge. 相似文献

A laboratory experiment by U.S. public health researchers Hall et al. claimed to demonstrate that a graphic picture-and-text warning label placed on so-called sugary drinks would substantially reduce parents' purchase of them for their children. Hall et al., however, misclassified the alleged “sugary drinks,” omitting those containing natural but equally harmful sugars such as fructose in fruit juice and lactose in milk. They also implied that artificially sweetened “non-sugary” drinks are harmless when available research indicates otherwise. The experiment was further invalidated by the fact that warning labels are illegal in the U.S., and those that Hall et al. used would not be permitted in any case because they partially obscured the manufacturer's brand label. There were many other methodological problems with Hall et al.'s experiment, among them the failure to do what any competent consumer researcher would do—namely ask the parents afterwards why they made the choices that they did. 相似文献

In a recent article published in this journal, Yuan and Fang (British Journal of Mathematical and Statistical Psychology, 2023) suggest comparing structural equation modeling (SEM), also known as covariance-based SEM (CB-SEM), estimated by normal-distribution-based maximum likelihood (NML), to regression analysis with (weighted) composites estimated by least squares (LS) in terms of their signal-to-noise ratio (SNR). They summarize their findings in the statement that “[c]ontrary to the common belief that CB-SEM is the preferred method for the analysis of observational data, this article shows that regression analysis via weighted composites yields parameter estimates with much smaller standard errors, and thus corresponds to greater values of the [SNR].” In our commentary, we show that Yuan and Fang have made several incorrect assumptions and claims. Consequently, we recommend that empirical researchers not base their methodological choice regarding CB-SEM and regression analysis with composites on the findings of Yuan and Fang as these findings are premature and require further research. 相似文献
