The Vietnam veteran on wal: The relation of post-traumatic stress disorder to criminal behavior

The purpose of this paper is to conceptualize the relationship of Post-Traumatic Stress Disorder (PTSD) in Vietnam veterans to criminal behavior. A conceptual framework is discussed which proposes that the disposition to criminal behavior is determined by whether or not the veteran enters into the survivor mode of functioning as a behavioral defense mechanism against the disorder. It is hypothesized that there exists a relationship between the severity of PTSD and the tendency to commit illegal acts. The Vietnam Era Stress Inventory (Wilson and Krauss, 1980) was used to assess PTSD among a volunteer national sample of Vietnam combat veterans (N = 114) participating in the Veterans Administration's counseling program known as Operation Outreach. The results strongly supported the hypothesis and indicated that combat role variables, exposure to stressors in Vietnam and the severity of PTSD were significantly correlated with criminal acts.     

How Superduper Does a Physicalist Supervenience Need to Be?

The standard formulations of the supervenience relation present the supervenience of one set of properties on another in terms of property correlations, without placing any constraints on the dependency relation concerned. This does not ensure that properties supervening upon phys-icalistically acceptable base properties are not themselves emergent in a way at odds with materialism. So physicalism needs 'superdupervenience'. I argue that, where supervenient and base properties are instantiated in the same individuals, Horgan's requirement of robust explanation is neither sufficient nor necessary for superdupervenience. His paradigm case is compatible with the supervenient property's being emergent. This and other unacceptable possibilities may be ruled out by means of a metaphysical constraint on the supervenience relation, which must be internal. Each individual causal power in the set associated with a given supervenient property must be numerically identical with a causal power in the set associated with its base property. Satisfying this condition is all that is needed to render supervenience superduper. In fact a wide variety of non-reductive physicalist accounts are implicitly or explicitly designed to meet this condition, and so are more similar than they seem.     

An investigation of preconditions necessary for the introduction of a campaign to promote breast self-examination amongst Zimbabwean women

This study examines elements of the health belief model as predictors of intentions to self-examine breasts in two samples of women. Undergraduate samples from London and Harare are compared on levels of knowledge of breast cancer and breast self-examination (BSE), and on scales measuring perceived susceptibility to breast cancer, exposure to information and experience of breast cancer and perceived costs, barriers and benefits of BSE. Analysis of results indicates that an education campaign to promote awareness and the practice of BSE which incorporates factors of the health belief model could increase the number of Zimbabwean women performing this valuable preventive health behaviour.     

Analysis of public verbal feedback as a staff management procedure

We evaluated public verbal feedback as a potentially effective and efficient means of improving institutional staff performance. Following baseline observations of the self-help training conducted by three groups of direct care staff with clients who had profound mental retardation, verbal feedback was presented publicly to individual staff during routine staff meetings. The feedback addressed the (in)frequency of the staffs training endeavors and required only a few minutes to present. Results indicated that each group of staff increased their client training when the public verbal feedback was provided. Probes of client self-help skills indicated that as the frequency of staff-conducted training increased, client skill acquisition improved. Generalization measures indicated that staff increased only those work behaviors for which they received feedback. Results are discussed regarding the efficiency of public verbal feedback as a means of improving staff performance, as well as the need for research to continue expanding and refining a technology of staff management.     

Chemical aversion conditioning in the treatment of alcoholism: further comments.

The literature on consummatory aversion (CA) conditioning in rats does provide a well-developed theoretical foundation for chemical aversion conditioning. Nevertheless, differences between rats and humans in CA learning suggest caution in extrapolating from the animal laboratory to the treatment of alcoholic patients. Serious methodological problems with studies of emetic therapy with alcoholics preclude unambiguous evaluation of its effects. Emetic therapy is an intrusive and relatively costly form of treatment which has not been shown to be more effective than alternative, less costly methods. The onus is on proponents of this method to demonstrate its specific advantages over alternative treatments.     

Operant-behavioural and cognitive-behavioural treatment for chronic low back pain.

Fifty-eight outpatients with chronic low back pain were randomly allocated to one of six experimental conditions. Four conditions were designated as treatment conditions and two as control conditions. The four treatment groups consisted of: cognitive treatment (either with or without relaxation training) and behavioural treatment (either with or without relaxation training). The cognitive and behavioural groups also received physiotherapy. The two control conditions consisted of: attention (physiotherapy plus discussion sessions) and no-attention (physiotherapy-only) conditions. All conditions, including the two controls, received the same physiotherapy back-education and exercise program. For the sample as a whole, improvements were obtained on measures of affective distress, functional impairment, medication use, pain-related dysfunctional cognitions and use of active coping strategies. These improvements were generally maintained at 6- and 12-month follow-ups. The combined psychological/physiotherapy treatment conditions improved significantly more than the physiotherapy-only conditions from pre to posttreatment on measures of pain intensity, self-rated functional impairment and pain-related dysfunctional cognitions. However, these differences were only weakly maintained at 6- and 12-month follow-ups. The behavioural conditions improved significantly more than the cognitive conditions from pre to posttreatment on the self-rated measure of functional impairment, but this difference was not maintained at 6- and 12-month follow-ups. Progressive relaxation training was found to make little contribution to either cognitive or behavioural treatments.     

Psychological predictors of HIV-preventive behavior among Zimbabwean students

This report is based on a study of 852 sexually active volunteer student teachers in Zimbabwe who were assessed on their AIDS risk reduction behavior and the Health Belief Model of Janz and Becker. The model posits that behavior modification occurs if there is knowledge of the disease and its severity, susceptibility, effective prevention, self- efficacy for prevention, accessible health care and advice, normative support for behavior change, and few barriers to action. Behavior change is measured by reduced numbers of sexual partners, increased condom use, and decreased prostitute contact. The 404 women showed no sex differences from the 448 men, except that men reported lower self- efficacy. The multiple linear regression analysis revealed that for men the Health Belief Model was significant and explained 15% of the variance (F=7.50, p.0001). Behavior risk reduction was predicted by self-efficacy (B=.10, p.0001), perceived barriers to action (B=-.19, p.01), and belief in the effectiveness of preventive practices (B-.10, p.001). The women's model was also significant and explained 12% of the variance (F=4.06, p.001). Preventive behavior was predicted by perceived susceptibility to infection (B=.19, p.01), access to health care and advice (B=.09, p.05), and belief in the efficacy of preventive measures (B=.06, p.05). Future research in planned to try to augment the Health Belief Model results by including the following variables: contact with AIDS-affected persons and specific barriers to action such as dependence on paid sex, the breakdown in traditional values, familial separation, and attitudes toward monogamy. Also, the role of alcohol and drugs in the context of sexual behavior will be considered. Other alternative models will also be examined, such as Bandura's social learning theory and Fishbein's theory of reasoned action. New theories which are uniquely applied to AIDS may need to be formulated.     

Thinking too much: introspection can reduce the quality of preferences and decisions

In Study 1, college students' preferences for different brands of strawberry jams were compared with experts' ratings of the jams. Students who analyzed why they felt the way they did agreed less with the experts than students who did not. In Study 2, college students' preferences for college courses were compared with expert opinion. Some students were asked to analyze reasons; others were asked to evaluate all attributes of all courses. Both kinds of introspection caused people to make choices that, compared with control subjects', corresponded less with expert opinion. Analyzing reasons can focus people's attention on nonoptimal criteria, causing them to base their subsequent choices on these criteria. Evaluating multiple attributes can moderate people's judgments, causing them to discriminate less between the different alternatives.
