Interaction Effects between Maternal Lifetime Depressive/Anxiety Disorders and Correlates of Children��s Externalizing Symptoms

We investigated the interaction effects between mother??s lifetime depressive/anxiety disorders and psychosocial correlates of 6 to 11 year-old children??s self-reported externalizing symptoms in the Quebec Child Mental Health Survey. A representative subsample of 1,490 Quebec children aged 6 to 11 years was selected from the original sample. We conducted multiple linear regression analyses using externalizing symptoms as reported by children through the Dominic questionnaire and multiple child, family and socioeconomic characteristics. Two variables interacted significantly with mother??s lifetime depressive/anxiety disorders to predict 6 to 11 year-old children??s self-reported externalizing symptoms: physical/sexual abuse and mother??s caring behaviours. Results underline the main contribution of mother-child relationship and stressful events in the association between mother??s lifetime depressive/anxiety disorders and children??s externalizing symptoms. It is suggested to develop preventive intervention programs oriented towards children of lifetime depressed/anxious parents who also report parent-child relational difficulties.     

Colateralization of Broca's area and the visual word form area in left-handers: fMRI evidence

Language production has been found to be lateralized in the left hemisphere (LH) for 95% of right-handed people and about 75% of left-handers. The prevalence of atypical right hemispheric (RH) or bilateral lateralization for reading and colateralization of production with word reading laterality has never been tested in a large sample. In this study, we scanned 57 left-handers who had previously been identified as being clearly left (N = 30), bilateral (N = 7) or clearly right (N = 20) dominant for speech on the basis of fMRI activity in the inferior frontal gyrus (pars opercularis/pars triangularis) during a silent word generation task. They were asked to perform a lexical decision task, in which words were contrasted against checkerboards, to test the lateralization of reading in the ventral occipitotemporal region. Lateralization indices for both tasks correlated significantly (r = 0.59). The majority of subjects showed most activity during lexical decision in the hemisphere that was identified as their word production dominant hemisphere. However, more than half of the sample (N = 31) had bilateral activity for the lexical decision task without a clear dominant role for either the LH or RH, and three showed a crossed frontotemporal lateralization pattern. These findings have consequences for neurobiological models relating phonological and orthographic processes, and for lateralization measurements for clinical purposes.     

Sharing differences: The inductive route to social identity formation

A dominant assumption in social science is that shared similarities are the foundation for social categorization and identification. Accordingly, heterogeneity should hinder social identity formation. This paper argues the opposite can also be true: in heterogeneous groups, strong social identities can be built on expressions of individuality (inductive social identity formation), instead of shared similarities (deductive social identity formation). Two experiments manipulate social identity formation (deductive vs. inductive social identity formation) and support this idea. Study 1 shows that in heterogeneous groups, inductive social identity formation can result in higher identification and perceived entitativity than deductive social identity formation. Study 2 manipulates heterogeneity and confirms that while deduction of a social identity fosters a strong sense of identification in homogeneous groups, in heterogeneous groups a strong sense of identification can be brought about through induction. This pattern is also visible in real within-group cooperation.     

Turning back the hands of time: Autobiographical memories in dementia cued by a museum setting

The current study examined the effects of cuing autobiographical memory retrieval in 12 older participants with dementia through immersion into a historically authentic environment that recreated the material and cultural context of the participants’ youth. Participants conversed in either an everyday setting (control condition) or a museum setting furnished in early twentieth century style (experimental condition) while being presented with condition matched cues. Conversations were coded for memory content based on an adapted version of Levine, Svoboda, Hay, Winocur, and Moscovitch (2002) coding scheme. More autobiographical memories were recalled in the museum setting, and these memories were more elaborated, more spontaneous and included especially more internal (episodic) details compared to memories in the control condition. The findings have theoretical and practical implications by showing that the memories retrieved in the museum setting were both quantitatively and qualitatively different from memories retrieved during a control condition.     

the inventory of recent life experiences for cancer patients (IRLE-C): A decontaminated measure of cancer-based hassles

Abstract

Cancer is recognized to have multifaceted stressful impact on all areas of a patient's life. Researchers commonly use self-report questionnaires, intended to measure stressors objectively. However, the item-content and response-format of such scales often tap physical and mental responses to stress, thereby contaminating prediction of adverse impact. This article reports the development and validation of English and French versions of the Inventory of Recent Life Experiences for Cancer Patients (IRLE-C) which is designed to minimize such “criterion-contamination”. This entailed (1) avoiding items reflecting physical or subjective distress; (2) rating stressors for degree of exposure only; and (3) use of an innocuous scale title. The initial item pool was administered serially to a sample of 100 Francophone breast-cancer and prostate-cancer patients. To guard against inflating reliability and validity estimates through capitalizing on chance, we administered the 30-item final scale to an independent sample of 96 Francophone breast-cancer and prostate-cancer patients undergoing radiation treatment. Following the item-selection step, factorial structure and validity analyses were performed using the combined French-speaking sample (n= 196). Second, we administered the English version of the scale to an English-speaking sample of 127 cancer patients (various cancer sites and stages). The measure showed good internal consistency (.94 and .89 for the Francophone and Anglophone samples respectively) and met criteria for a 2-week test-retest reliability (r= .70 for the item-selection subsample and .80 for the cross-replication sub-sample). Correlations between the IRLE-C and the POMS Total Mood Disturbance were around .60 for both the Francophone and Anglophone samples. Avoiding contamination (through content and format) without losing its relationship to subjective distress, the IRLE-C appears a useful instrument for applying the stress-process model in oncology to establish clear distinctions among stressors, mediators, reactions, and consequences.     

L'INVENTAIRE DE RESOLUTION DE PROBLEMES PERSONNELS: UNE PERSPECTIVE METACOGNITIVE*

Studies on personal problem solving demonstrate important variations in intra- and interindividual problem solving performances. These differences have been associated with different levels of subject's psychological distress. Recently, several investigators have attempted to identify meta-cognitive factors associated with fluctuations in problem solving performance and variations in subject's level of mental health. The purpose of the present study was to examine the psychometric qualities of the French version of the Problem Solving Inventory (PSI). The 35-item questionnaire assess people's attitudes toward their personal problem solving competence. Reliability, factorial structure and construct validity of the instrument were evaluated with two different samples of subjects. Results indicated that the French version of the PSI has high internal consistency and, as predicted, a tri-dimensional factorial structure. The observed relation between subject's appraisal of their personal problem solving abilities and level of psychological distress support the discriminant properties and the concurrent validity of the PSI.     

A structured pictorial questionnaire to assess DSM-III-R-based diagnoses in children (6–11 years): Development,validity, and reliability

This paper presents a structured pictorial instrument, the Dominic questionnaire, to assess mental disorders in 6- to 11-year-old children. Ninety-nine drawings represent situations corresponding to DSM-III-R based ADHD, CD, ODD, MDD, SAD, OAD, and SPh. However, cognitive limitation of 6- to 11-year-old children do not allow for time-related measurement. The instrument takes 15–20 min to administer. Reliability and validity of the Dominic questionnaire were studied in Parent DISC-2 positive and negative outpatient and general population samples and against clinical judgement. The pictorial approach provides acceptable test-retest reliability and the instrument makes standardized assessment possible for children as young as 6 years of age.This investigation was supported by the National Health Research and Development Program (Ottawa) grant #6605-2780-42. The authors wish to thank L. Houde and S. Lepine for their collaboration and J. J. Breton, P. Cohen, K. Minde, K. Munir, and D. Shaffer for their suggestions and editorial comments.     

Evidence for selective target processing with a low perceptual load flankers task

In this article, we demonstrate that selective target processing is possible when the perceptual load of the task is low. We presented a row of three items with two different identities: one identity for the target letter and one for the two flankers (B. A. Eriksen & C. W. Eriksen, 1974). Such stimulus arrays have been defined as low-load displays (Lavie & Tsal, 1994). We investigated whether subjects could ignore the irrelevant flankers, which were never response alternatives, by manipulating the predictive relationship between the flankers and the response (Miller, 1987). In a high-correlation block, the identity of the flankers was highly predictive of the target identity, whereas in a lowcorrelation block, the predictive value of the flankers was reduced. We varied (1) whether or not the target location was precued, (2) the flanker’s category (digit vs. letter), (3) the target-flanker proximity (near = 3° vs. far = 5°), and (4) the size of the characters. The results indicate that subjects were influenced by the predictive value of near flankers and that the magnitude of this effect was jointly modulated by the target-flanker categorical overlap and by the size of the characters. In contrast, null flanker effects were obtained for far letter flankers in the precue condition, and for far digit flankers, regardless of attentional cuing. These findings (1) are inconsistent with suggestions (Lavie, 1995) that irrelevant stimuli automatically capture attention, and (2) support the notion that target-flanker distinctiveness plays a role when the perceptual load of the task is low.     

Short versus long term gains of a cognitive-behavioral social skills program targeting the giving and receiving of criticism

Seventy-four university undergraduates (40.2% male and 59.8% female) reporting difficulty in giving and receiving criticism were randomly assigned to either a training group consisting of cognitive behavioral criticism skills including behavior rehearsal, modeling, coaching, cognitive restructuring, or to a control group. Dependent measures were given at pre-test, post-test, and one year follow-up. Included were self-report measures consisting of Fear of Negative Evaluation (FNE), Criticism Concerns Scale (CCS), Criticism Self-Esteem Giving and Receiving Scales, and behavioral role-play measures consisting of judges’ global ratings of subject’s verbal and nonverbal criticism behaviors in role-play scenarios with a live actor. Results for the self-report measures, FNE, and Criticism Self-Esteem Receiving showed both training program and control groups improved at post-test, but only the training program group maintained gains at one year follow-up. For the CCS and Criticism Self-Esteem Giving, the training program group improved over time, yet was only significantly different from control group at post-test. Results were discussed in terms of the pro-active nature of giving criticism versus the more reactive nature of receiving criticism.     

Heterogeneity of Incentives for Physical Activity and Self-Efficacy in Highly Active and Moderately Active Women Exercisers

The purpose of this investigation was to examine whether persons exercising 2 times per week or less versus 3 times per week or more, with intentions to maintain current level of activity form a homogenous group in terms of motivational features. A group of 86 women recruited from local fitness clubs reported on their exercise incentives, self-efficacy, exercise behavior, and exercise intentions. A discriminant function analysis revealed that self-efficacy and incentives for stress reduction and mental health discriminated highly active from moderately active women. The implications of these findings are discussed in terms of stage theory and research in exercise adherence.
