Psychometric Properties of the Short Self-Regulation Questionnaire (SSRQ) in a South African Context
Self-regulation (SR), an important construct within the psychological well-being context, involves the ability to monitor behaviour, to contrast it with reference values and to introduce adjustments where necessary. A lack of validated measures of SR in the South African context has contributed to the current caveat in our knowledge of the potential importance of this construct. This investigation aimed to establish the utility of the Short Self-Regulation Questionnaire (SSRQ; Carey, Neal & Collins, 2004) in a South African context. This short version of the original Self-Regulation Questionnaire (SRQ; Brown, Miller & Lawendowski, 1999) was completed by a group of 385 undergraduate psychology students. Factor analysis produced 7 factors, all of which showed significant positive correlations with other measures of psychological well-being. This first step toward establishing the importance of SR in non-Western cultures reflected positively on the potential use of the SSRQ in large epidemiological studies. 相似文献

The Multidimensional Blood/Injury Phobia Inventory (MBPI) was developed from a theoretical framework to characterize a broad range of feared stimuli and phobic reactions associated with this pathology. The MBPI consists of 40 items that cross 4 types of stimulus content (injections, hospitals, blood, injury), 5 types of phobic responses (fear, avoidance, worry, fainting, disgust), and a self versus other focus. This study reports on administration of the MBPI to 558 undergraduates, 9 of whom had blood/injury phobia. The instrument had a Cronbach's alpha of .91 and demonstrated good concurrent validity, convergent validity, and discriminant validity. One large factor emerged in an unrotated principal components analysis, suggesting that blood/injury phobia is a unitary psychometric construct. Exploratory factor analyses revealed a 6-factor solution defined by stimulus content domains and fainting, each of which may be important to consider clinically when assessing the unique concerns of treatment-seeking individuals. 相似文献

An Internet‐based survey was administered in Japan to compare mental health of and stigma toward unemployed individuals, workers with regular employment, and workers with irregular employment. Unemployed individuals showed higher scores for both anxiety/depression and disturbance of activities, as well as faced more stigma than did employed individuals. In addition, the factor structure of stigma that unemployed individuals have toward the unemployed was the same as that previously found for university students and employed individuals. Financial strain and stigma were the factors with the greatest influence on the mental health of unemployed individuals. 相似文献

Formalizing a “psychology of science” today will constrain intellectual freedom in ways more likely stultifying than liberating. We should be more improvisational in seeking ideas from academic psychology to develop a more comprehensive purview. I suggest that a psychology of science should look at systematic theology and empirical theology. Liberal theologians have long experience trying to distill from religion those structural aspects that affirm openness in a search for truth. Science, as well as religion, has its myths and rituals, but theologians are more experienced than scientists at a large mythohistorical scale. There are distortions in the extreme degree to which psychological science has traditionally emphasized empiricism, positivism, hypothesis testing, and falsifiability. I argue for less critical reduction and more creative augmentation. This could include looking outside academia at cognitive competencies of people in trades. Exaggerated parsimony is an old story. This is illustrated by the opposition to David Hartley's 1749 theory of neural oscillations. There is an inexorable “margin of uncertainty” where scientific prediction and control can never outstrip the new uses to which human beings put ideas. Facts and values interact in this margin; theology has long made a home there, but scientists sometimes have been excessive in rejecting the “naturalistic fallacy.” There is also often a degree of disingenuousness in psychology's reluctance to take subjective phenomena seriously; here there may be lessons in how empirical theology has handled subjectivity, as well as in taking an honest look at the way much of the methodology of experimental psychology incorporates subjective assessments. Feist's book is a start, but these things need more thought before codifying a psychology of science. 相似文献

Human delay discounting is usually studied with experimental protocols that use symbols to express delay and amount. In order to further understand discounting, we evaluated whether the absence of numbers to represent reward amounts affects discount rate in general, and whether the magnitude effect is generalized to nonsymbolic situations in particular. In Experiment 1, human participants were exposed to a delay‐discounting task in which rewards were presented using dots to represent monetary rewards (nonsymbolic); under this condition the magnitude effect did not occur. Nevertheless, the magnitude effect was observed when equivalent reward amounts were presented using numbers (symbolic). Moreover, in estimation tasks, magnitude increments produced underestimation of large amounts. In Experiment 2, participants were exposed only to the nonsymbolic discounting task and were required to estimate reward amounts in each trial. Consistent with Experiment 1, the absence of numbers representing reward amounts produced similar discount rates of small and large rewards. These results suggest that value of nonsymbolic rewards is a nonlinear function of amount and that value attribution depends on perceived difference between the immediate and the delayed nonsymbolic rewards. 相似文献

We describe a set of Tufnel problems that arise when repeated use of a fixed-point scale precipitates failures to assess a full range of subjective experiences. As empirical evidence, participants in Study 1 periodically reported their depth of mind wandering on either 5- or 7-point Likert scales during a sustained attention task. The proportion of participants providing maximum scale ratings increased quickly over time-on-task and did so more quickly for the 5-point than for the 7-point group. Participants in Study 2 completed the same task using a 10-point scale before indicating whether and where they could have used a scale extended to “11” during the task. Slightly more than 20% of participants reported needing a scale extension. This Need for 11 was associated with differences in both reports of mind wandering depth and task performance. We conclude that Tufnel problems warrant methodological consideration and reflect interesting constraints on human judgment. 相似文献

IntroductionInternet Gaming Disorder (IGD) was introduced for the first time within the “conditions for further study” in the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association, and a systematic review has concluded that the only available instrument for its measurement is the Problem Video Game Playing scale (PVP). Nevertheless, this scale was presented as a diagnostic tool for adolescents, and to date no study has analyzed its properties amongst adults.ObjectiveThe aim of the study was to analyze and compare the diagnostic and psychometric properties of the PVP in adult and adolescent gamers.MethodTwo samples of adult (n = 525) and adolescent (n = 384) gamers completed a survey including patterns of play, PVP, Severity of Dependence Scale, and other measures of playing to excess.ResultsConfirmatory factor analyses revealed that the scale presents a one-factor structure that is similar to that of the original version, both in adults and adolescents. Construct validity was supported by highly significant associations between the PVP and all alternative measures of playing to excess. On the other hand, reliability values were lower than in previous studies.ConclusionsThe PVP scale's properties are appropriate for the measurement of problem video gaming in adults as well as in adolescents, but studies with clinical assessments are still needed before any cutoff value for diagnosis can be established. 相似文献

High-resolution electron microscopy (HREM) at the atomic scale has been applied to study the edge dislocation redistribution between interfaces in Ge/Ge0.5Si0.5/Si(0?0?1) heterostructures. Our results provide a direct explanation that plastic relaxation of the GeSi buffer layer proceeds owing to motion of Lomer-type dislocation complexes consisting of a pair of complementary 60° dislocations with the ends of the {1?1?1} extra planes being located at a distance of ~2–12 interplanar spacings from each other. It is demonstrated that edge dislocations belonging to the upper and lower interfaces become arranged one under the other and dislocation walls are formed. The distributions of tension and compression in the [0?0?1] direction between two edge dislocations, obtained by processing the HREM image, testify to superposition of strain fields. 相似文献

随机选取小学4~6年级被试86名,从辅助策略、比例推理策略的策略选择和策略效用三方面,通过五种类型的天平任务考察儿童比例推理策略的表现。结果表明:(1)儿童最常使用手指动作辅助加工基本数量信息。辅助策略的使用率随年龄增长而减少,五年级开始使用出声思维,反映出元认知能力的发展。(2)在正式学习比例知识之前,各年级儿童都能使用两种以上策略,也能根据任务难度自发产生新策略,具备策略选择的多样性和适应性。其中,三个年级均能使用定性比例推理策略(双维策略,IIIA策略,补偿策略),表明儿童初步认识了距离和重量两个维度的共变关系。此外,六年级儿童能使用"运货车策略"将冲突问题灵活地化解为简单问题。(3)儿童的错误策略表现为:在冲突任务中盲目使用补偿策略、简单策略或加法策略。(4)分层回归分析表明,在控制年龄后,儿童的一般推理能力越高,其对重量策略的依赖性越低,且可能更容易发掘距离维度的意义,其使用运货车策略的频次更多。此外,一般推理能力对解决冲突类天平任务的正确次数有正向预测作用。 相似文献

Currently research exploring paruresis and parcopresis, anxiety relating to urinating and having bowel motions in public respectively is limited. While there are several validated measures of paruresis, no valid measure assessing parcopresis is currently available. The present study investigates the development and validation of the Shy Bladder and Bowel Scale (SBBS) which assesses both paruresis and parcopresis. Two participant groups were utilised to validate this scale, a student psychology cohort (n = 387) and a public cohort (n = 334). An eight-item two-factor model was identified in the psychology cohort and confirmed in the public cohort. The two-factor SBBS was found to be a valid and reliable measure of paruresis and parcopresis. Paruresis and parcopresis-related concerns were associated with social anxiety in both cohorts. Subscales for both paruresis and parcopresis (i.e. difficulty, interference and distress) were positively correlated, suggesting individuals are likely to report similar levels of concerns across both conditions. Further, individuals self-identifying with either paruresis or parcopresis reported significantly higher scores on the respective SBBS subscales than non-identifying paruresis and parcopresis individuals. The SBBS also demonstrated strong test–retest reliability in a small sample of adults (n = 13). Overall, the developed scale provides clinicians and researchers with a valuable tool to evaluate both paruresis and parcopresis. 相似文献
