Do traumatic events influence the clinical expression of compulsive hoarding?

Traumatic experiences have been posited as one potential catalyst for the abrupt onset of obsessive-compulsive symptoms including compulsive hoarding. To determine whether traumatic life events (TLEs) might influence the expression of compulsive hoarding in obsessive-compulsive disorder (OCD), interview responses to the Posttraumatic Stress Disorder module of the Structured Clinical Interview for DSM-IV (SCID) were examined in 180 individuals with OCD. Compared to individuals with OCD who did not meet criteria for hoarding, participants classified as hoarders (24% of the sample) were significantly more likely to have reported at least one TLE in their lifetime. Patients who met criteria for hoarding and who had also experienced TLEs had significantly greater hoarding symptom severity than those hoarders not exposed to trauma. This association was found to be robust. That is, the relationship between TLEs and hoarding symptom severity was not better accounted for by age, age of OCD onset, depressive symptoms, general OCD symptomatology, or mood and anxiety comorbidity. Closer examination revealed that the clutter factor of compulsive hoarding (and not difficulty discarding or acquisitioning) was most strongly associated with having experienced a traumatic event.     

Is more always better? An examination of the nonlinear effects of perceived organizational support on individual outcomes

A wide range of research has accumulated detailing the positive associations of perceived organizational support (POS) with desirable workplace outcomes (e.g., high performance, high commitment, low deviance). In the process, there has been an implicit assumption that these relationships are linear, with ever-increasing POS resulting in ever-increasing positive outcomes. However, there are theoretical and practical reasons to question whether these relationships may be nonlinear rather than linear. Our results offer support for the notion that the relationships between POS and key individual outcomes rated by the supervisor may best be represented as nonlinear. We conclude by highlighting the implications for both theory and practice.     

Children's memory of recurring events: is the first event always the best remembered?

Three experiments were conducted to examine the effect of age (4–5 and 6–8 years) and retention interval on children's ability to remember separate occurrences of a repeated event that varied in terms of content (items, dialog, etc.) Experiment 1 explored children's ability to recall the first versus last occurrence of a series of six events, at either one week or six weeks delay. Experiments 2 and 3 explored children's ability to identify the position of items in terms of their order of presentation within the series across two retention intervals. Overall, the results revealed clear age differences in children's performance. In general, the 6‐ to 8‐year‐old children performed better on all tasks than the 4‐ to 5‐year‐old children. Further, the older children showed relatively good memory of the first and last items compared to the middle items, although the last items were more likely to be forgotten or misplaced in the sequencing tasks over time than the first items. For the younger children, the patterns of results were sometimes but not always consistent with that of the older children. The relevance and generalisability of these findings to the legal setting are discussed as well as directions for future research. Copyright © 2002 John Wiley & Sons, Ltd.

Examining the Factor Structure of the Self-Compassion Scale in Four Distinct Populations: Is the Use of a Total Scale Score Justified?

This study examined the factor structure of the Self-Compassion Scale (SCS) using a bifactor model, a higher order model, a 6-factor correlated model, a 2-factor correlated model, and a 1-factor model in 4 distinct populations: college undergraduates (N = 222), community adults (N = 1,394), individuals practicing Buddhist meditation (N = 215), and a clinical sample of individuals with a history of recurrent depression (N = 390). The 6-factor correlated model demonstrated the best fit across samples, whereas the 1- and 2-factor models had poor fit. The higher order model also showed relatively poor fit across samples, suggesting it is not representative of the relationship between subscale factors and a general self-compassion factor. The bifactor model, however, had acceptable fit in the student, community, and meditator samples. Although fit was suboptimal in the clinical sample, results suggested an overall self-compassion factor could still be interpreted with some confidence. Moreover, estimates suggested a general self-compassion factor accounted for at least 90% of the reliable variance in SCS scores across samples, and item factor loadings and intercepts were equivalent across samples. Results suggest that a total SCS score can be used as an overall mesure of self-compassion.     

Is personality disorder inherited? An overview of the evidence

Genetic factors appear to be of considerable importance in determining normal variation in personality. This is suggested by family, twin, and adoption studies as well as by indirect findings based on animal and psychophysiological studies. In contrast, there is consistent evidence that the contribution of shared family environment is minimal. Despite difficulties in defining personality disorder, it appears that many types of personality disorder, in particular schizotypal personality disorder and antisocial personality disorder/criminality, are also influenced genetically. The genetic transmission of normal personality traits and disorder is most easily explained by the contribution of multiple genes of small effect rather than by single-gene inheritance. Recent advances in molecular genetics have led to the localization of genes of minor effect for some traits. This raises the possibility of detecting a molecular basis of traits and disorders such as personality and personality disorder.Anita Thapar is supported by a Research Training Fellowship from the Medical Research Council.     

Is the grass always greener on the other side? Social comparisons of subjective well-being

This study investigates subjective well-being (SWB) among residents of Munich (n?=?380) and Venice (n?=?545) with respect to their individual SWB and their judgments of SWB for residents of their own city and those living in the other city. Our results indicate that egocentrism rather than striving for self-enhancement guided people's judgments of SWB. For people with low individual SWB, a below-average effect was found, whereas for people with high individual SWB, a better-than-average effect emerged. Also in line with the egocentrism approach, judgments of individual SWB were positively related to the judgments of SWB for residents of their own city, but unrelated to SWB of those living in the other city. Implications for future research are discussed.     

Liberation or Poverty? An Indirect Assessment of the Impact of Potential Future Events on Society

A methodology is proposed and tested which suggests that one can evaluate the potential impact of future decisions or events on various societal groupings (poor vs. rich; black vs. white) by correlating the values promoted by the event or decision with the values desired by the societal groupings. It is assumed that the correlation represents the potential value satisfaction of the event for the societal grouping. Nine judges were asked to rate the contributions of two events to 18 social values. The values of six societal income groupings from "Under $4,000" to "Over $15,000" (Rokeach & Parker, 1970) were correlated with the values judged to be promoted by the two events. One event suggested that U.S. monies be shifted from military spending to urban aid; as expected, the values promoted by this event were more highly correlated with those of lower income groups than with those of higher income groups. The second event suggested that women have equal opportunities in professional and managerial jobs; as expected, the values of higher income groups would be served more by this event than would the values of lower income groups. This study substantiates that the assessment methodology proposed is feasible, meaningful, and that raters make consensual and reliable judgments that discriminate the events as predicted. It was also found that the value-satisfaction index is correspondent with the public opinions of societal groupings toward events similar to those used in this study.     

Is Sense of Coherence Lowered by Negative Life Events?

The present study aimed to contribute to research on sense of coherence (SOC) by answering the following questions: (1) Is SOC lowered by negative life events? (2) Is an initially low or moderate SOC lowered more by negative life events than an initially high SOC? One thousand and twelve female nurses in Sweden responded to a questionnaire on two occasions with more than 1 year apart. On both occasions the participants reported if they have experienced any of 22 negative life events during the past year and rated their SOC. The results gave negative answers to both questions. In addition, SOC was found stable over time and seems to prevent the experience of negative life events. In sum, these results corroborate Antonovsky’s main postulate that SOC is a salutogenic disposition.     

Is depression the past tense of anxiety? An empirical study of the temporal distinction

It has long been recognised that depression and anxiety share a common core of negative affect, but research on similarities and differences between these two emotions is growing. The focus of the current study was on whether the timing of a triggering event can determine whether the dominant emotional reaction is depression or anxiety. It was hypothesised that aversive events in the past would elicit more depression than anxiety, whereas the same aversive events in the future would elicit more anxiety than depression. We created temporally varied versions of vignettes describing aversive events occurring at either time, and asked participants to rate the extent to which the events would elicit feelings of depression or anxiety. Results indicated that adverse past events elicited much higher ratings of anticipated depression and adverse future events elicited much higher ratings of anticipated anxiety. Implications for understanding these two emotions and depressive and anxiety disorders are discussed.     

Is the future always brighter than the past? Anticipation of changes in the personal future after recall of past experiences

People tend to hold an optimistic view of their futures. Using a novel paradigm to examine the anticipated change from the personal past to the personal future, we found that the future was not always perceived as brighter than the past. College students (N = 156) recalled positive and negative personal events of various situations. Following each recall, they imagined a future personal event involving the same situation. Participants expected over half of the events to change in either upward or downward directions, depending on the valence of the past events. In addition, participants anticipated greater changes in domains of less stability, and Asians anticipated greater changes than European Americans. Anticipated future changes were further associated with psychological well-being. The findings shed new light on future event simulation.     

Is more choice always worse? Age differences in the overchoice effect

Current research on the overchoice effect has been mainly conducted from an adult point of view and with adult subjects. This study investigates whether children, adolescents, and seniors suffer the same negative consequences as adults when facing an overabundance of choice. Findings showed that the overchoice effect did not equally extend to all age groups. While adolescents were affected by the phenomenon in a very similar way as adults, children and seniors suffered fewer negative consequences of an overabundance of choice. Theoretical and practical implications are discussed.     

Is Scripture the origin of the Halakhah?

Scripture, in particular the Pentateuch, forms the natural starting point for any inquiry into origins in Judaism. The question answered here derives from a simple fact: the Pentateuch is privileged within the Rabbinic system, which links as much of the Halakhah to the Pentateuchal law codes as it possibly can. So it is quite natural to treat Scripture as the base-line and the Halakhic category-formations as the variable, in seeking the origin of the system. But what happens when we treat the system as the base-line and Scripture as the variable? Then we see that the Halakhic system viewed as a coherent statement does not originate in Scripture. Scripture is not the origin of the Halakhah. Why not? Because of this paradox: Scripture is necessary for the Halakhic system. But Scripture is insufficient for the Halakhic system. The Halakhic system is necessary for Scripture. The Halakhic system is sufficient without Scripture. It requires only Scripture's facts ‐ and these on their own form no system.
