An analogue study of the effects of Psychological Debriefing on eyewitness memory

Sixty-one participants from the community participated in a randomised controlled trial of group debriefing to assess the effect of this intervention upon memory for a stressful event. Participants were randomly allocated to one of three groups: debriefing; debriefing with an experimenter confederate present (who supplied three pieces of misinformation to the group regarding the stressful event); and a no-treatment control. All groups were shown a very stressful video and were again reviewed after 1 month. Members of the debriefing group where a confederate provided misinformation were more likely to recall this misinformation as fact than members of the other two groups. The debriefing group was also more accurate in their recall of peripheral content than the confederate group. Across all groups, participants were found to be more accurate at central rather than peripheral recall yet more confident for incorrect memories of the video than correct memories.     

Does Friendship Matter? An Examination of Social Physique Anxiety in Adolescence1

The role of peer group composition and influence variables on social physique anxiety was examined. Peer network data were gathered on 375 adolescents (181 male, 194 female). Females reported experiencing higher social physique anxiety, more pressure and encouragement to alter their physique from peers, greater body‐related discussion, and greater identification with the peer group than did males. Regression analyses revealed 2 peer influence variables—peer pressure and relative attractiveness of peers—to be significant predictors of social physique anxiety. A third variable—extent to which the individual identified with peer network—was a significant predictor for females. Results are discussed in reference to previous research, and future research directions are identified.     

Development of an abbreviated Social Phobia and Anxiety Inventory (SPAI) using item response theory: the SPAI-23

An abbreviated version of the Social Phobia and Anxiety Inventory (SPAI) was developed using methods based in nonparametric item response theory. Participants included a nonclinical sample of 1,482 undergraduates (52% female, mean age = 19.4 years) as well as a clinical sample of 105 individuals (56% female, mean age = 36.4 years) diagnosed with either generalized (73%) or specific social phobia (27%). Twenty-three of the 45 SPAI items demonstrated good discrimination along the social anxiety continuum. In addition, option characteristic curves (OCCs) indicated that the SPAI's 7-point scale may generate errors in ranking individuals. Thus, options were collapsed to improve item performance. No gender differences emerged between any of the items' OCCs, suggesting that items function similarly among men and women. The abbreviated version also correlated highly with the original 45-item SPAI and exhibited similar patterns of correlations with measures of social anxiety. The SPAI-23 has considerable practical benefits, including a screening of both social and agoraphobic anxiety as well as decreased assessment and scoring time.     

Use of traditional medicine by HIV-infected individuals in South Africa in the era of antiretroviral therapy

As antiretroviral therapy (ART) becomes more available in African countries, the potential for interaction with traditional medicines becomes more important. We carried out a cross-sectional survey among individuals with moderate or advanced HIV disease attending a workplace clinic providing ART in South Africa to determine prevalence of traditional medicine use, source, recommended products and costs. Among 44 clinic attendees (100% male, median age 42 years, 30 taking ART), 37 (84%) reported ever using traditional medicines, 25 obtained from a healer or herbalist, eight from their own fields and four from a pharmacy. Fourteen of the 44 (32%) were currently using traditional medicines, most frequently African potato (9/14) and Aloe vera (3/14). Seven out of 30 persons taking ART (23%) reported currently using traditional medicines. Participants spent 4 - 27 pounds per month on traditional medicines. Traditional medicine use is common among individuals with moderate and advanced HIV disease. Concomitant use with ART has the potential for drug interactions and should be discussed routinely in ART counselling. Further work is warranted to investigate whether commonly used traditional medicines interact with ART in vivo.     

Specificity of cognitive and behavioral variables to Positive and Negative Affect

The Tripartite Model proposes that a combination of greater Negative Affect (NA) and reduced Positive Affect (PA) contributes to depressive symptoms. The purpose of this study was to test a model of affective experience in which cognitive variables (i.e., negative cognitions and appraisals) are uniquely related to NA but not PA, and in which behavioral variables (i.e., activity participation) are uniquely associated with PA but not NA. Participants included 88 spousal Alzheimer caregivers (mean age = 74 years). Multiple regression models, in which negative cognitions (i.e., helplessness, blames self, and negative appraisals) and activity participation (i.e., frequency of engaging in social and recreational activities) were used to predict depressive symptoms, PA and NA. Results indicated that while helplessness, blaming oneself, negative appraisals, and activity participation all significantly predicted depressive symptoms, only negative cognitive variables significantly predicted NA, and only activity participation significantly predicted PA. These data confirm that depressive experience consists of two relatively independent components - increased Negative Affect and reduced Positive Affect - which have unique correlates in negative cognitions and activity participation. If confirmed, the findings suggest the utility of focusing interventions on each of these components in the management of depressive symptoms.     

Use of samples differing markedly in salience may encourage use of a single-code/default strategy in matching-to-sample in pigeons

To test the hypothesis that pigeons will only code the more salient sample when samples differ markedly in salience, pigeons were trained with samples consisting of a 2-s presentation of food (highly salient sample) and an 8-s presentation of keylight (less salient sample). During retention testing, pigeons tended to respond at longer delays as if an 8-s keylight sample had been presented. This finding is consistent with use of a single-code/default strategy in which only the 2-s food sample was coded and the comparison associated with an 8-s keylight sample was selected by default in the absence of memory for the salient 2-s food sample. Hence, a marked difference in sample salience appears to encourage use of a single-code/default strategy.     

Adult Attachment in Children Raised by Parents with Schizophrenia

Maternal schizophrenia is known to have an adverse effect on the quality of mother–infant interaction; and children of parents with severe mental illness run a higher risk of poor mental health and social outcomes. Hence, children raised by a parent with schizophrenia may be less likely to attain secure attachment, although there is less evidence so far to support this. Moreover, there is a lack of research in this field that focusses on the needs and experiences, the strengths and vulnerabilities, of the children themselves. Qualitative methods are thus needed to generate new insights and hypotheses. The present study uses semi-structured interviews with 23 adults who, as children, were raised with a parent who experienced schizophrenia. This reveals a range of attachment problems, resulting in difficulties in forming secure adult relationships. Problems with trust and intimacy were found to be common.     

The Credentialing Problems of Foreign Trained Personnel from Asia and Africa Intending to Make their Home in Canada: A Social Psychological Perspective

This study examined the experiences of a sample of skilled immigrants to Canada from Asia and Africa who were currently experiencing credentialing problems (N?=?180). Most respondents had advanced postsecondary training and a job requiring a high level of skill prior to emigrating, but many were unable to obtain equivalent work in Canada. In reaction, they took work for which they were overqualified, volunteered, had their qualifications assessed, and upgraded their training. Most respondents were surprised and upset that it was so difficult for them to obtain a suitable job in their profession, and many felt that immigrants were discriminated against by Canadian employers. The policy implications of this “brain waste” are discussed.
