Risk and Protective Factors for Comorbid Posttraumatic Stress Disorder among Homeless Individuals in Treatment for Substance-Related Problems

Homeless individuals undergoing treatment for substance use disorders (SUD) can pose clinical challenges. Posttraumatic stress disorder (PTSD) symptoms have been observed in the most difficult clients. The study sample consisted of 51 homeless individuals, 9 women and 42 men, undergoing consultation for SUD in Montreal. The mean age was 46 years (SD = 7.19). Of the sample, 49% had a potential PTSD diagnosis. Most participants had the following characteristics: an alcoholic parent, a history of an early trauma, and little social support. The participants with a potential PTSD diagnosis were significantly more likely to have had an alcoholic parent, to have experienced an early trauma, and to use more maladaptive coping strategies. The study results and limits are discussed.     

Action-centred negative priming: Evidence for reactive inhibition

Experiments are described in which the spatial relationship between a stimulus and respondent is held constant in terms of visual and body-centred coordinates, while the complexity of the response is manipulated. It is demonstrated that the degree of complexity of an action directed to the same spatial location determines the level of negative priming observed. This result supports the notions that (1) inhibitory selection mechanisms act on action-centred representations, and (2) the level of inhibition is reactive to the relative potency of the evoked action. The results are also discussed in terms of alternative explanations of negative priming. It is concluded that the results are inconsistent with theories that do not involve inhibitory selection mechanisms.     

What's in a Forename? Cue Familiarity and Stereotypical Thinking

Recent research has characterized categorical thinking as an essential component of the person perception process. Yet relatively little is known about the myriad factors that moderate the accessibility of this mode of thought. With regard to this we hypothesized that the subjective familiarity of a person's forename may play an important role in triggering categorical thinking. Specifically, category-based knowledge may be more accessible when triggered by familiar than unfamiliar forenames. We report the results of three experiments that supported this prediction. Relative to unfamiliar names, participants required less time to verify the gender of familiar forenames (Experiment 1) and semantic priming was more pronounced when stereotype-related material followed the presentation of familiar than unfamiliar items (Experiment 2). Also, familiar forenames attracted more extreme gender-based evaluations than their unfamiliar counterparts (Experiment 3). We consider the theoretical and methodological implications of these findings for a variety of issues in person perception.     

Moods and Quality of Life

In modern society, flow and stress are well-known terms in the theoretical discussions of the good life, subjective well-being and quality of life. The purpose of this article is to present the results of a phenomenological analysis of flow and stress experiences in everyday life. The analysis yielded a distinction between different phenomenological dimensions identified as arising in different combinations within concrete experience of flow and stress. These different dimensions were characterised by different feelings, different experiences of time and different experiences of the world. The results are discussed and interpreted in the light of Martin Heidegger's, Otto Friedrich Bollnow's and F.C.J. Buytendijk's theories of moods and feelings. Flow and stress experiences are phenomenologically interpreted as moods and classified as a modern version of basic polarities of moods as described by Bollnow and Buytendijk. Lastly, the concept of mood is emphasised as a specific entrance to the subjective and experienced dimensions involved in the complex concepts of quality of life, the good life and happiness.     

The anatomy of loneliness

Loneliness is a potent but little understood risk factor for broad-based morbidity and mortality. We review five social neurobehavioral mechanisms that may account for this association. The evidence suggests that different mechanisms explain short-term and long-term effects, and that the long-term effects operate through multiple pathways. Implications for the design of interventions are discussed.     

Eliciting salient beliefs in research on the theory of planned behaviour: The effect of question wording

The authors of the theory of reasoned action (TRA) and its extension, the theory of planned behaviour (TPB) recommend that researchers who use these theories to investigate the determinants of a given behaviour should first conduct an elicitation study to identify the modal salient beliefs in the target population. In spite of the importance accorded to salient beliefs by the TRA/TPB, the elicitation stage has received little research attention. This paper reports a detailed analysis of beliefs about “being more physically active in the next 12 months.” A general population sample of 213 adults completed a questionnaire while attending a research centre for a series of tests. The findings showed that the beliefs that were elicited by questions designed to prompt affective outcomes (like or enjoy, dislike or hate) differed systematically from those that were elicited by the traditional questions designed to prompt instrumental out-comes (advantages and disadvantages). Whether this resulted in different final sets of modal salient beliefs was found to depend on the particular decision rule that was employed. An alternative decision rule is proposed, based on maximizing the degree of overlap between the modal set and the full set of salient beliefs generated by the sample. The index of overlap can be used to gauge the adequacy of using a modal set of a given size to represent the salient beliefs of the whole sample. In the current dataset, the optimal modal set for “advantages and disadvantages” was associated with only 26 percent overlap with the salient beliefs of the whole sample, which was judged to be insufficient. In such cases, a better strategy may be to ask participants to generate and rate their own beliefs.     

A Statistic Strikes Back

A recent college dropout relates her view of the pressures on students from society's Great Plan for the young, critically evaluates some of the implicit assumptions of the higher education establishment, and reacts to the three articles following on college dropouts by Williams, Leach and Goetz, and Berger. This paper enables the reader to learn not only about but from the dropout by reminding him that statistics sometimes interfere with our view of the people behind them, who are our only legitimate concern.
