Interference resolution in major depression

In two experiments, we investigated individual differences in the ability to resolve interference in participants diagnosed with major depressive disorder (MDD). Participants were administered the “Ignore/Suppress” task, a short-term memory task composed of two steps. In Step 1 (“ignore”), participants were instructed to memorize a set of stimuli while ignoring simultaneously presented irrelevant material. In Step 2 (“suppress”), participants were instructed to forget a subset of the previously memorized material. The ability to resolve interference was indexed by response latencies on two recognition tasks in which participants decided whether a probe was a member of the target set. In Step 1, we compared response latencies to probes from the to-be-ignored list with response latencies to nonrecently presented items. In Step 2, we compared response latencies to probes from the to-be-suppressed list with response latencies to nonrecently presented items. The results indicate that, compared with control participants, depressed participants exhibited increased interference in the “suppress” but not in the “ignore” step of the task, when the stimuli were negative words. No group differences were obtained when we presented letters instead of emotional words. These findings indicate that depression is associated with difficulty in removing irrelevant negative material from short-term memory.     

Mediating relationship between body mass index and the direct measures of the Theory of Planned Behaviour on physical activity intention

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.     

The effectiveness of psychotherapeutic interventions for bereaved persons: a comprehensive quantitative review

Previous quantitative reviews of research on psychotherapeutic interventions for bereaved persons have yielded divergent findings and have not included many of the available controlled outcome studies. This meta-analysis summarizes results from 61 controlled studies to offer a more comprehensive integration of this literature. This review examined (a) the absolute effectiveness of bereavement interventions immediately following intervention and at follow-up assessments, (b) several of the clinically and theoretically relevant moderators of outcome, and (c) change over time among recipients of the interventions and individuals in no-intervention control groups. Overall, analyses showed that interventions had a small effect at posttreatment but no statistically significant benefit at follow-up. However, interventions that exclusively targeted grievers displaying marked difficulties adapting to loss had outcomes that compare favorably with psychotherapies for other difficulties. Other evidence suggested that the discouraging results for studies failing to screen for indications of distress could be attributed to a tendency among controls to improve naturally over time. The findings of the review underscore the importance of attending to the targeted population in the practice and study of psychotherapeutic interventions for bereaved persons.     

Voices of Outreach: The Construction of Identity and Maintenance of Social Ties Among Chabad-Lubavitch Emissaries

Fundamentalists typically avoid influences from the outside world and form intense social bonds with members of their own group. Yet, active fundamentalists must create relationships with the objects of their missionary action, the Other. In this article I address the connections between the cultural practice of missionary work and the formation and maintenance of social ties among ultra-Orthodox Jewish missionaries belonging to the fundamentalist Hasidic sect Chabad-Lubavitch. These missionaries attempt to bring Jews to the beliefs and practices of Chabad by hosting Jews at Sabbath meals. This missionary act is an utterance that "speaks" with multiple voices, indexing the missionaries as both friendly members of their local Jewish community and ideal Lubavitchers. Through these meals, the missionaries engage not only the local Jews but also other Lubavitchers in dialogue, constructing a community that transcends face-to-face interaction.     

An attachment classification of desperate love

The assessment utility of attachment theory constructs for research and diagnostic purposes is being increasingly explored and demonstrated. This study focuses on the association between desperate love and a modification of Ainsworth, Blehar, Waters, and Wall's (1978) taxonomy of attachment styles, hypothesizing that the experience of desperate love will be positively associated with the dependent and resistant/ambivalent attachment styles with no gender differences. The findings based on multivariate regression analyses generally corroborate the attachment style hypotheses, although with significant gender differences. Discussion focuses on the possible contrasts in the intrapsychic experience of desperate love for men and women as well as indications of causal trends for future research.     

The role of attachment in the post-divorce experience

The loss of the spouse resulting from marital breakdown appears to be a central component of post-divorce distress. However, comparatively little empirical research has examined the nature of this broken bond or its impact on the divorced adult. This study tests the hypothesis that the continuing positive feelings for the ex-spouse following divorce are very salient for the individual and are related to increased distress. Sixty recently divorced women selected from court records were randomly assigned to one of three conditions in which they recalled the ex-spouse in a positive, loving interaction (PS); the ex-spouse in a conflictual interaction (C); or a friend in a positive, loving interaction (PS). A post-recall thought sampling procedure was employed to measure the frequency of thoughts about the ex-spouse. The subjects in the PS condition had significantly more post-recall thoughts of the ex-spouse and significantly more thoughts about coping than those in either the C or the PF conditions. The implications of these data for theories of post-divorce adaptation and adult attachment are discussed.     

Identity status measurement across contexts: variations in measurement structure and mean levels among White American, Hispanic American, and Swedish emerging adults

We conducted this study to examine measurement equivalence and mean differences in identity status across 3 ethnic/cultural contexts: White American, Hispanic American, and Swedish. We used the Extended Objective Measure of Ego Identity Status II (EOM-EIS-II; Bennion & Adams, 1986), a commonly used instrument in the identity status literature. We conducted analyses to ascertain the extent to which the EOM-EIS-II functioned equivalently in 3 ethnically/culturally different samples. The internal structure of the measure was consistent across contexts. When we statistically controlled effects of age and gender, mean differences tended to be largely cross-cultural at the observed level of analysis but to be both cross-ethnic and cross-cultural at the latent level of analysis. This divergence in findings was found despite the limited age range represented in each of the samples. We therefore concluded that measurement error may have played a role in these differences and that data gathered using the EOM-EIS-II should be analyzed using latent variable methods. We discuss results in terms of using the EOM-EIS-II with diverse populations.
