Nightmares have been shown to be robust predictors of self‐harm risk, beyond depressive symptoms and hopelessness at times. However, few studies have investigated associations between nightmare content and increased self‐harm risk. This study explored associations of thematic nightmare content with history of self‐harm, and risk of self‐harm phenomena the morning following a nightmare. A mixed‐method diary study was performed. Prospective nightmare reports were obtained from 72 participants. A total of 47 nightmare reports met inclusion criteria and were analyzed for themes using inductive thematic analysis. Chi‐square and bootstrap Pearson's correlation tests were performed to assess the associations between nightmare themes and self‐harm history, and risk of self‐harm phenomena following a nightmare. “ Powerlessness to Change Behavior” was associated with a history of self‐harm engagement, whereas “Financial Hardship” indicated reduced risk. Themes were not significantly associated with increased risk of self‐harm phenomena following a nightmare. Content may be of use in detecting lifetime history of self‐harm engagement, particularly in populations where disclosure is seen as taboo. However, nightmare symptom severity remains a better indicator of risk. Evidence for the utility of nightmare content in assessing immediate self‐harm risk is presently lacking. Replication with increased power is recommended.  相似文献

Background. There is evidence that children who are taught to read later in childhood (age 6–7) make faster progress in early literacy than those who are taught at a younger age (4–5 years), as is current practice in the UK. Aims. Steiner‐educated children begin learning how to read at age 7, and have better reading‐related skills at the onset of instruction. Therefore, it is hypothesized that older Steiner‐educated children will make faster progress in early literacy than younger standard‐educated controls. Samples. A total of 30 Steiner‐educated children (age 7–9) were compared to a matched group of 31 standard‐educated controls (age 4–6). Method. Children were tested for reading, spelling, phonological awareness, and letter knowledge at three time points during their first year of formal reading instruction and again at the end of the second year. Results. There were no significant differences between groups in word reading at the end of the first and second year or reading comprehension at the end of the second year; however, the standard group outperformed the Steiner group on spelling at the end of both years. The Steiner group maintained an overall lead in phonological skills while letter knowledge was similar in both groups. Conclusions. The younger children showed similar, and in some cases, better progress in literacy than the older children; this was attributed to more consistent and high‐quality synthetic phonics instruction as is administered in standard schools. Consequently, concerns that 4‐ to 5‐year‐olds are ‘too young’ to begin formal reading instruction may be unfounded.  相似文献

It is essential that outcome research permit clear conclusions to be drawn about the efficacy of interventions. The common practice of nesting therapists within conditions can pose important methodological challenges that affect interpretation, particularly if the study is not powered to account for the nested design. An obstacle to the optimal design of these studies is the lack of data about the intraclass correlation coefficient (ICC), which measures the statistical dependencies introduced by nesting. To begin the development of a public database of ICC estimates, the authors investigated ICCs for a variety outcomes reported in 20 psychotherapy outcome studies. The magnitude of the 495 ICC estimates varied widely across measures and studies. The authors provide recommendations regarding how to select and aggregate ICC estimates for power calculations and show how researchers can use ICC estimates to choose the number of patients and therapists that will optimize power. Attention to these recommendations will strengthen the validity of inferences drawn from psychotherapy studies that nest therapists within conditions.  相似文献

Research on psychological influences on physiology primarily focuses on biological responses during stressful challenges, and how those responses can become dysregulated with prolonged or repeated exposure to stressful circumstances. At the same time, humans spend considerable time recovering from those challenges, and a host of biological processes involved in restoration and repair take place during normal, non-stressed activities. We review restorative biological processes and evidence for links between psychosocial factors and several restorative processes including sleep, wound healing, antioxidant production, DNA repair, and telomerase function. Across these biological processes, a growing body of evidence suggests that experiencing negative emotional states, including acute and chronic stress, depressive symptoms, and individual differences in negative affectivity and hostility, can influence these restorative processes. This review calls attention to restorative processes as fruitful mechanisms and outcomes for future biobehavioral research.  相似文献

We investigated whether two basic forms of deductive inference, Modus Ponens and Disjunctive Syllogism, occur automatically and without awareness. In Experiment 1, we used a priming paradigm with a set of conditional and disjunctive problems. For each trial, two premises were shown. The second premise was presented at a rate designed to be undetectable. After each problem, participants had to evaluate whether a newly-presented target number was odd or even. The target number matched or did not match a conclusion endorsed by the two previous premises. We found that when the target matched the conclusion of a Modus Ponens inference, the evaluation of the target number was reliably faster than baseline even when participants reported that they were not aware of the second premise. This priming effect did not occur for any other valid or invalid inference that we tested, including the Disjunctive Syllogism. In Experiment 2, we used a forced-choice paradigm in which we found that some participants were able to access some information on the second premise when their attention was explicitly directed to it. In Experiment 3, we showed that the priming effect for Modus Ponens was present also in subjects who could not access any information about P(2). In Experiment 4 we explored whether spatial relations (e.g., "a before b") or sentences with quantifiers (e.g., "all a with b") could generate a priming effect similar to the one observed for Modus Ponens. A priming effect could be found for Modus Ponens only, but not for the other relations tested. These findings show that the Modus Ponens inference, in contrast to other deductive inferences, can be carried out automatically and unconsciously. Furthermore, our findings suggest that critical deductive inference schemata can be included in the range of high-level cognitive activities that are carried out unconsciously.  相似文献

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1 participants were 157 applicants competing for 10 staff positions at a large university located in a southern city in the People's Republic of China. In Study 1, potential fakers received a warning message, whereas nonfakers received a nonwarning (control) message. Study 2 participants were 386 Chinese college students applying for membership of a popular student organization at the same university where Study 1 was conducted. In Study 2, the warning and control messages were randomly assigned to all applicants. Results showed some promise for the proposed procedure, but several practical issues need to be considered.  相似文献

This study explored undergraduate students’ interpersonal responses, namely general feelings toward and desire for further social interaction with trans persons in a helping context. Secondarily, this study explored the relationship between participants’ intrinsic empathy, interpersonal curiosity and interest in further interaction. Two hundred fifty-one undergraduates at a moderate sized university in the southeastern United States served as participants. In order to assess baseline levels of empathy and curiosity, participants in session 1 completed the Interpersonal Reactivity Scale (Davis 1983) and the Interpersonal Curiosity Scale (Litman and Pezzo 2007). One week later, during session 2, the same students assumed the role of a peer counselor and read 1 of 4 (male, female, male-to-female, female-to-male) randomly assigned versions of an intake form completed by a fictitious peer client. Each version was identical, with the exception of the gender identity of the peer client. Participants completed various measures of affect and interest in further interaction. Male participants reported less willingness to interact with, and the strongest negative feelings toward the FTM peer client. Men reported highest willingness to interact with the MTF client and showed the lowest negative reactions towards the MTF client. Female participants’ scores on willingness to interact and on negative reactions were similar across all four intake form versions. Contrary to expectations, baseline levels of empathy and curiosity did not impact responses to gender expression. Further investigation is needed to elucidate the factors associated with anti-transgender prejudice particularly in the context of helping relationships.  相似文献
