Trajectories of resilience, resistance, and distress during ongoing terrorism: The case of Jews and Arabs in Israel.

This is the 1st longitudinal examination of trajectories of resilience and resistance (rather than ill-being) among a national sample under ongoing threat of mass casualty. The authors interviewed a nationally representative sample of Jews and Arabs in Israel (N = 709) at 2 times during a period of terrorist and rocket attacks (2004?2005). The resistance trajectory, exhibiting few or no symptoms of traumatic stress and depression at both time points, was substantially less common (22.1%) than has previously been documented in studies following single mass casualty events. The resilience trajectory, exhibiting initial symptoms and becoming relatively nonsymptomatic, was evidenced by 13.5% of interviewees. The chronic distress trajectory was documented among a majority of participants (54.0%), and a small proportion of persons were initially relatively symptom-free but became distressed (termed delayed distress trajectory; 10.3%). Less psychosocial resource loss and majority status (Jewish) were the most consistent predictors of resistance and resilience trajectories, followed by greater socioeconomic status, greater support from friends, and less report of posttraumatic growth.

Mothers with serious mental illness: When symptoms decline does parenting improve?

Serious mental illnesses (SMI) and problems with parenting are associated, but the link between change in psychiatric symptoms and change in parenting over time has not been examined. Three hypotheses were tested. Hypothesis 1: As symptoms decline, parenting stress will decline and parenting nurturance will improve. Hypothesis 2: High prior levels of symptoms have a continuing impact on parenting over time, persisting even when symptoms remit. Hypothesis 3: Both symptoms and parenting are influenced by contextual factors; taking these into account diminishes the association between them. With the use of latent growth curve modeling and an economically and racially diverse sample of mothers with SMI (N = 294), evidence supporting Hypothesis 1 was found, but there was no support for Hypothesis 2. For Hypothesis 3, contextual factors predicted both symptoms and parenting; accounting for context diminished the association between symptoms and parenting stress, but context did not completely explain the association between symptoms and parenting.

The effects of temporary inactivation of the orbital cortex in the signal attenuation rat model of obsessive compulsive disorder.

Rats undergoing extinction of lever pressing after an external feedback for this behavior was attenuated by extinguishing its Pavlovian association with the reward (signal attenuation) exhibit compulsive lever pressing. The present study tested the effects of temporary inactivation of the orbital cortex in rats undergoing extinction of lever pressing that was or was not preceded by signal attenuation (post-training signal attenuation and regular extinction, respectively). Orbital inactivation led to a nonspecific decrease in lever pressing in rats undergoing post-training signal attenuation and to the emergence of compulsive-like behavior in rats undergoing regular extinction. These results suggest that orbital inactivation and extinguishing a Pavlovian stimulus-reinforcer contingency have a similar effect on lever pressing and are in line with previous findings implicating the orbital cortex in mediating the effects of previously acquired stimulus-reinforcer associations on operant behavior.

Solution-focused counselling in Canadian outpatient dietetic practice.

PURPOSE: The use of solution-focused counselling (SFC) in dietetics was examined to determine the demand for an SFC teaching tool for registered dietitians. METHODS: A cross-sectional web-based survey was conducted within the Dietitians of Canada cardiology, eating disorders, and consulting networks, with dietitians who practised in an outpatient setting. Dietitians were surveyed on the seven core components of SFC. RESULTS: Responses (n=58) were received from dietitians practising in seven provinces, who tended to be younger (mean age=44) and who had practised for a mean of 15 years. The entire sample reported use of at least four of the seven core components of SFC. All respondents were interested in receiving a counselling teaching tool for dietitians. CONCLUSIONS: All respondents were using components of SFC in their outpatient practices. The efficaciousness of SFC in dietetic practice has yet to be determined.     

Family functioning and interactive patterns in the context of infant psychopathology.

Family functioning and mother–infant relational patterns were examined in 38 clinic-referred infants and 34 matched non-referred infants. Referred infants were diagnosed with the Diagnostic Classification for Zero to Three. On the family level, referred families showed significantly lower family functioning in all domains of emotional and instrumental communication, regardless of the specific infant's diagnoses. On the dyadic level, referred mothers were more intrusive and their infants were more withdrawn during dyadic interactions. Clinic-referred mothers reported higher levels of phobia and depression. Global family functioning was predicted by the infant's clinical status, maternal intrusiveness, and maternal psychopathology. Infant mental health clinicians need to address both family level and dyadic level of functioning, regardless of the reason for the infant's referral.

A prospective study of risk and resilience factors associated with posttraumatic stress symptoms and depression symptoms among Jews and Arabs exposed to repeated acts of terrorism in Israel.

In the first prospective study, to our knowledge, of the impact of ongoing terrorism and political violence, we analyzed nationally representative data from 560 Jews and 182 Arabs in Israel over a 6-month period. Based on Conservation of Resources (COR) theory (Hobfoll, 1989, 1998), we predicted that exposure to terrorism and political violence would result in psychosocial and economic resource loss and resource lack, which in turn, would be primary predictors of increases in symptoms of posttraumatic stress (PTS) and depression. We also predicted that trauma exposure and PTS symptoms, in particular, would be related to ethnocentrism and support for political violence. Furthermore, based on theory and prior research, we predicted that posttraumatic growth (PTG) would be related to a worsening of symptoms of distress and that distress would be related to increased ethnocentrism and support for extreme political violence for their “cause.” Women, older individuals, and Arabs (compared with Jews) were more likely to have continued psychological distress over time. In addition, using simultaneous equation modeling, we found good fit for a structural model that partially supported our hypotheses. Psychosocial resource loss, PTG, and social support had direct and indirect effects on psychological distress. Political attitudes tended to harden over time but were not prospectively related to PTS or depressive symptoms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Possible selves and delinquency.

The relationship between possible selves and delinquency is explored. In this study, 238 youths between the ages of 13–16 who varied in the degree of their delinquency were asked to describe their possible selves. Although many similarities were found among their hoped-for selves, the groups of youth differed markedly in the nature of their expected and feared selves. The balance between expected possible selves and feared possible selves was the particular focus. Balance is hypothesized to occur when expected possible selves are offset by countervailing feared selves in the same domain (e.g., expecting a job, but fearing being unemployed). It was found that the officially nondelinquent youths were quite likely to display balance between their expectations and fears, unlike the most delinquent youth. In contrast, a conventional measure of self-esteem that indicates how people feel about themselves currently did not predict degree of delinquency.

Rethinking individualism and collectivism: Evaluation of theoretical assumptions and meta-analyses.

Are Americans more individualistic and less collectivistic than members of other groups? The authors summarize plausible psychological implications of individualism-collectivism (IND-COL), meta-analyze cross-national and within-United States IND-COL differences, and review evidence for effects of IND-COL on self-concept, well-being, cognition, and relationality. European Americans were found to be both more individualistic--valuing personal independence more--and less collectivistic--feeling duty to in-groups less--than others. However, European Americans were not more individualistic than African Americans, or Latinos, and not less collectivistic than Japanese or Koreans. Among Asians, only Chinese showed large effects, being both less individualistic and more collectivistic. Moderate IND-COL effects were found on self-concept and relationality, and large effects were found on attribution and cognitive style.

Model-based invariants for 3-D vision

Invariance under a group of 3-D transformations seems a desirable component of an efficient 3-D shape representation. We propose representations which are invariant under weak perspective to either rigid or linear 3-D transformations, and we show how they can be computed efficiently from a sequence of images with a linear and incremental algorithm. We show simulated results with perspective projection and noise, and the results of model acquisition from a real sequence of images. The use of linear computation, together with the integration through time of invariant representations, offers improved robustness and stability. Using these invariant representations, we derive model-based projective invariant functions of general 3-D objects. We discuss the use of the model-based invariants with existing recognition strategies: alignment without transformation, and constant time indexing from 2-D images of general 3-D objects.
