This article reports an effectiveness case study of the individual systemic therapy of a 22‐year‐old Portuguese woman with a diagnosis of paranoid personality disorder, conducted in a university‐based clinic in Lisbon, Portugal. Data were analysed using the hermeneutic single‐case efficacy design, a non‐experimental interpretive approach that aims to determine whether change occurred, whether change was due to therapeutic strategies, and what in therapy caused the change. Results indicate that the treatment was effective and that de‐pathologising Pamina's condition and genogram‐based exploration techniques played a crucial role in her recovery.  相似文献

The present experiments assessed the effects of different manipulations between cue preexposure and cue-outcome pairings on latent inhibition (LI) in a predictive learning task with human participants. To facilitate LI, preexposure and acquisition with the target cues took place while participants performed a secondary task. Presentation of neither the target cues nor the target outcome was anticipated based on the instructions. Experiment 1 demonstrated the LI effect in the new experimental preparation. Experiment 2 analyzed the impact on LI of different activities that participants performed during the interval between preexposure and acquisition. Experiment 3 assessed LI as a function of changes in the secondary task cues made between preexposure and acquisition, namely presenting novel cues and reversing the cue-outcome contingencies. All of the manipulations in Experiments 2 and 3 resulted in a decrease in LI. The attenuation of LI by these manipulations challenges most current theories of learning and is best accommodated by Conditioned Attention Theory (Lubow, Weiner, & Schnur, 1981).  相似文献

Lesbian parents, their children and grandparents ‘do family’ in rich and diverse ways. This article draws on innovative grounded theory research using qualitative, multi‐generational family interviews with twenty lesbian‐parented families living in Victoria, Australia. The intersection between the public and the private in lesbian family life has been seriously neglected by family researchers, and in particular the perspectives of family members other than the lesbian parents themselves. This article addresses the question of ‘How members of lesbian‐parented families define and describe their family’, and the results reported here focus on children's and grandparents' views, because they are the voices less well represented in the literature. Children and grandparents straddle both mainstream and marginalized spaces as they negotiate contemporary family life. We examine the interface and tensions between the traditional and the transformative, and the implications of these findings for family therapists are briefly discussed.  相似文献

The aim of this work was to develop a Spanish adaptation of the Revised Competitive State Anxiety Inventory-2. The scale was translated and its psychometric properties were analyzed with data from a sample of 149 athletes. Exploratory and confirmatory factor analyses were performed which supported a 16-item CSAI-2R assessing the three hypothesised dimensions of anxiety: Somatic anxiety, Cognitive anxiety, and Self-confidence. Overall fit of the model was good with a value of .97 for Comparative and Non-Normed Fit Indexes, and .045 for Root Mean Square Error of Approximation. Cronbach alpha coefficients for the factors ranged from .79 to .83. It is concluded that this version shows adequate properties, in terms of its dimensionality and internal consistency. Guidelines are also provided for future research on its validity as a measure of state anxiety in competitive situations.  相似文献

Although the effectiveness of cognitive-behavioral treatment in posttraumatic stress disorder (PTSD) is well established, few studies examined its effects on individual PTSD symptoms and possible mechanisms of improvement in symptoms. In a previous randomized controlled study [Ba?og lu, M., Salciog lu, E., Livanou, M., Kalender, D., & Acar, G. (2005). Single-session behavioral treatment of earthquake-related posttraumatic stress disorder: A randomized waitlist controlled trial. Journal of Traumatic Stress, 18, 1-11] a single session of behavioral treatment involving self-exposure instructions was highly effective in reducing earthquake-related PTSD. In the present study we examined the effects of treatment on each PTSD symptom and which symptoms improved early in treatment. Because the intervention focused solely on behavioral avoidance, we hypothesized that avoidance would be the first symptom to change and that reduction in avoidance would generalize to all other symptoms. The results showed significant between-groups treatment effect on only behavioral avoidance early in treatment (week 6). At 6 months post-treatment recovery rates ranged from 60% to 89% for 15 PTSD symptoms, including the numbing symptoms. Lack of improvement in avoidance was associated with lack of improvement in 12 symptoms. The critical process in recovery thus appeared to be increased sense of control associated with reduction in avoidance. These findings imply that live exposure to fear cues designed to enhance sense of control might be sufficient for recovery from PTSD.  相似文献

The authors studied the effect of 3 modes of managerial influence (managerial oversight, ethical leadership, and abusive supervision) on counterproductivity, which was conceptualized as a unit-level outcome that reflects the existence of a variety of intentional and unintentional harmful employee behaviors in the unit. Counterproductivity was represented by an objective measure of food loss in a longitudinal study of 265 restaurants. After prior food loss and alternative explanations (e.g., turnover, training, neighborhood income) were controlled for, results indicated that managerial oversight and abusive supervision significantly influenced counterproductivity in the following periods, whereas ethical leadership did not. Counterproductivity was also found to be negatively related to both restaurant profitability and customer satisfaction in the same period and to mediate indirect relationships between managerial influences and distal unit outcomes.  相似文献

This study examined the precompetition temporal patterning of competitive anxiety components in 42 athletes with disability who participated at the national level and at the national trials for the Paralympic Games in a variety of sports. All subjects completed a modified version of the Competitive State Anxiety Inventory-2 which measures intensity and direction of the competitive anxiety response on three occasions before competition (1 wk., 2 hr., and 20 min.). Analysis suggested that for cognitive and somatic dimensions athletes with disabilities show a similar precompetition anxiety response to athletes without disability. However, there appear to be some differences, particularly in the intensity of self-confidence, as athletes with disability reported a reduction of self-confidence just prior to competition.  相似文献

Two conditioned taste aversion experiments with rats were conducted to establish if a target taste that had received a prior pairing with illness could be subject to second-order conditioning during extinction treatment in compound with a flavor that also received prior conditioning. In these experiments, the occurrence of second-order conditioning was indicated by protection from extinction of the aversion elicited by the target taste. This possibility, although intuitive, deserves attention because current associative models [e.g., Rescorla, R. A., & Wagner, A. R. (1972). A theory of Pavlovian conditioning: variations in the effectiveness of reinforcement and nonreinforcement. In A. H. Black & W. F. Prokasy (Eds.), Classical conditioning II: Current research and theory (pp. 64-99). New York: Appleton-Century-Crofts.] predict exactly the opposite outcome, namely, that compound extinction of two CSs should result in enhanced extinction.  相似文献

The aggressive display in Betta splendens is particularly prominent, and vital to its adaptation to the environment. Methylmercury is an organic variation of Hg that presents particularly pronounced neuro-behavioral effects. The present experiments aim to test the effect of acute and chronic poisoning with methylmercury on the display in Bettas. The animals were poisoned by trophic means in both experiments (16 ug/kg in acute poisoning; 16 ug/kg/day for chronic poisoning), and tested in agonistic pairs. The total frequency of the display was recorded, analyzing the topography of the agonistic response. The methylmercury seems to present a dose- and detoxification-dependent effect on these responses, with a more pronounced effect on motivity in acute poisoning and on emotionality in the chronic poisoning. It is possible that this effect could be mediated by alteration in the mono-amino-oxidase systems.  相似文献
