This study explores the relationships between spiritual meaning and social support from the religious community and problem behaviors, anger and depression in 128 dementia caregivers. The results suggest a mediating role of anger in the relationship between the appraisal of problem behaviors and depression. Support from the religious community is directly and negatively associated with anger, but the relationship between spiritual meaning and anger is mediated by caregivers’ appraisals of problem behaviors, suggesting that spiritual beliefs might help caregivers to find meaning in caregiving experiences and thus appraise care recipients’ behavioral problems as less stressful.  相似文献

Aluja, Kuhlman, and Zuckerman (2010) developed an instrument for American and Spanish populations (Zuckerman-Kuhlman-Aluja Personality Questionnaire [ZKA-PQ]) that includes 4 facets for each 5 basic traits of Zuckerman's psychobiological personality model. This new instrument is intended to improve the previous measure based on the same personality model, the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), by including the narrower traits (facets) defining the factors. This article explores the convergent and discriminant validity of the new instrument relative to the NEO PI-R in a sample from the Spanish general population. A series of exploratory factor analyses comparing both instruments was conducted. Results showed good convergent and discriminant validity between both instruments, although the ZKA-PQ had a slightly better structure than the NEO PI-R. The results support the validity of the ZKA-PQ factor domains and the facets composing them. The new instrument might be useful in both applied and research settings.  相似文献

The aim of this study was to compare the psychometric properties (normal distribution values, reliabilities and factor structure) of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and the Temperament and Character Inventory revised (TCI-R). The total sample consisted of 482 subjects (53.1% men and 46.9% women) from diverse age. Results showed somewhat better psychometric properties, like reliability and facet-factor structure, for the ZKA-PQ than the TCI-R. The expected five-factor facet structure of the ZKA-PQ was clear found. However, the seven-factor structure of TCI-R was not clear and it did not show a clear distinction between Temperament and Character factors. When ZKA-PQ and TCI-R variables are analyzed together, the ZKA-PQ factors are related to the Character as well as the Temperament factors. In some cases they represent the opposite poles of ZKA-PQ factors; for example, Neuroticism versus Self-Directiveness and Aggression versus Cooperativeness. Some are directly and highly related to ZKA-PQ factors; for example, Sensation Seeking and Novelty Seeking, Extraversion and Reward Dependence, Neuroticism and Harm Avoidance, and Activity and Persistence.  相似文献

A mediation model of the relation between gender and attitudes toward affirmative action in favor of working women was tested. Four mediation variables were considered: perceived unfairness in the situation of working women, perceived threat to the non-designated group (men), self-esteem, and gender self-concept (masculinity and femininity). 192 women and 128 men, with differing occupations, participated. Gender affects individuals' attitudes toward affirmative actions for women, mediated by perceived unfairness in the situation of working women, perceived threat to the non-designated group, and feminine self-concept. Implications for research and practice are discussed.  相似文献

We investigated the effect of handedness and sex on: (i) sulcal contours defining PO and PTR and (ii) volume estimates of PO and PTR subfields in 40 left- and 42 right-handers. Results show an effect of handedness on discontinuity of the inferior frontal sulcus (IFS: < 0.01). Discontinuity of IFS was observed in: 43% left- and 62% right hemispheres in right-handers and in 65% left- and 48% right-hemispheres in left-handers. PO volume asymmetry was rightward in left-handed males (= 0.007) and females (= 0.02), showed a leftward trend in right-handed males (= 0.06), and was non-asymmetrical in right-handed females (= 0.96, i.e. left- and right-hemisphere PO volumes did not differ significantly). PO volume asymmetry in males differed significantly between handedness groups (= 0.001). Findings indicate a high degree of variability in the sulcal contours of PO and PTR and volume asymmetry of PO: the factors sex and handedness can explain some of this variability.  相似文献

Some argue that the medical model and the experimental design that underlies the use of treatment manuals to prove the efficacy of a psychotherapeutic treatment clashes with the theoretical basis of family therapy. From the point of view of the empirically supported treatments (ESTs) movement, treatment manuals are the operationalization of the independent variable in a clinical trial; the therapist is only part of the procedure and the therapeutic relationship is a confounding variable. Applying that logic to the practice of family therapy might be considered a heresy. This article argues that paradoxically, this heresy has a lot to offer the practice of family therapy. Research is the best way to answer questions like ‘how does family therapy work?’ ‘What makes ‘good therapy’ good?’ ‘Do therapists do what they say they do'? This article recommends an alternative framework for integrating ESTs into practice by proposing empirically informed guides to practice which, being less formulaic, encourage process‐outcome research, are coherent with the systemic model and do not constrain the therapist's creativity. Such guidelines allow therapists to use manuals flexibly so that they deepen the understanding of the process of therapy. We encourage you to listen to the JFT Editor, Mark Rivett, as he interviews the author on Manuals in the Practice and Research of Family Therapy.

Several parameters related to the timing, grip force and load force involved in a precision grasping task were studied in patients with Parkinson's disease (PD) at different moments of medication and healthy controls, using a sensorized anthropomorphic device which was totally adapted to the human hand. The aim of this work was to carry out an accurate study of the reach-load-grip-hold-place-release subtasks to identify any physical motor impairment, its relation to medication and Parkinsonian strategies. Twenty seven patients in ON and OFF-like medication moments, and twenty seven age-matched controls took part in the experiment, which consisted of using the index finger and the thumb to perform a precision motor task involving different experimental objects. Visual cues were used as distracting elements. Results showed several motor parameters impaired in OFF-like medication moment but attenuated in ON state, suggesting a medication effect on the performance of the task.  相似文献

The objective was to study male and female rats exposed to Activity-Based Anorexia (ABA; simultaneous exposition to food restriction and free access to an activity wheel) under two conditions of sound attenuation, by means of different arrangements of wheels (standard versus isolation) in the laboratory room. Regardless of the sound attenuation condition, all but one male and one female with access to wheels had to be removed from the experiment, but extended ABA endurance was found in rats in the sound attenuation condition. Furthermore, significantly lower levels of running were observed in both males and females under the sound attenuation arrangement in the isolation condition. The results suggest that external stimulation plays a role in the activity displayed by rats exposed to ABA, and that the reduction of external stimulation diminishes running but does not protect rats from developing ABA.  相似文献

Recently, sigma-1 receptor modulators have been considered drugs with an interesting therapeutic potential for the treatment of anxiety. However, there is no clear information in preclinical studies about the possible effects of sigma-1 ligands on anxiety in experimental animal models. Therefore, the present study examined the effects of (+)SKF 10,047 (2-8 mg/kg, ip), a sigma-1 agonist, on anxiety, tested in two classical laboratory models (social interaction test and elevated plus maze). (+)SKF 10,047 (8 mg/kg) produced a significant decrease of social investigation in the "social interaction test", whereas in the "elevated plus maze", the drug (4 and 8 mg/kg) provoked a significant reduction in the number of entries into open arms, as well as in the time spent in this area, as compared with the control group, without affecting motor activity. Overall, these findings indicate that (+)SKF 10,047 exhibits an anxiogenic-like profile in mice. It is suggested that anxiogenic effects of this sigma-1 ligand could be related to its potent ability to modulate diverse neurotransmitter systems involved in anxiety regulation.  相似文献

The purpose of this study was to examine the relationship between burnout and job satisfaction among nursing professionals. The sample consisted of 316 staff nurses. The study was longitudinal, and not randomized. The gap between Time 1 (T1) and Time 2 (T2) was one year. Hierarchical regression analysis showed empirical evidence of the significant and negative effect of burnout (i.e., Emotional exhaustion and Depersonalization dimensions) at T1 on job satisfaction in T2. Significant results were also obtained that showed the influence of job satisfaction at T1 on burnout at T2 (i.e., Depersonalization dimension). The study concludes that there is a bidirectional and longitudinal relationship between burnout and job satisfaction. However, longitudinal effects of burnout at T1 on job satisfaction on T2 (i.e., burnout as antecedent of job satisfaction) are stronger than vice-versa (i.e., job satisfaction as antecedent of burnout).  相似文献
