On becoming oriented to inpatient addiction treatment: inducting new patients and professionals to the recovery movement.

Professionals starting on a rehabilitation unit must join the unit culture, learning to work side by side with addiction counselors who are often "in recovery." They then face the task of integrating self-help and psychological models of treatment. Patients undergo their own induction, first accepting the attribution of "addict," and then joining a subculture of recovery that provides ego support and a sense of higher purpose. Group therapy is the primary avenue of acculturation for both patients and professionals.

Darwinian evolution of social behavior: implications for group psychotherapy.

Medicine typically looks to biology for guidance in examining complexity. Application of biological principles to social processes has not been easy. Still, we need not abandon biology in the study of complex social phenomena. Biologists have come to view the study of proximate form and function (revealed by disciplines such as anatomy, psychology and physiology) versus the study of how the form and function ultimately "got to be" (revealed by disciplines such as ethology and sociobiology) as distinct and complementary levels of understanding (Lorenz 1981; Mayr 1982). Though we cannot undertake in this paper explication of the value of understanding the ultimate, as well as the proximate, in studying biological phenomena, interested readers will find a comprehensive discussion in Mayr. The evolutionary principles structuring social interactions are becoming understood and hold promise as a biologically valid system for organizing and guiding the study of complex social behaviors (Essock-Vitale and Fairbanks 1979; Kofoed and MacMillan 1987). Psychological processes have evolved in varying complexities as mechanisms to enable and guide social behavior, increasing the probability that such behavior will be adaptive in a wide variety of circumstances (Trivers 1971). Dynamic and social psychologies describe the proximate internal and interactive intricacies that have resulted from this process but cannot help us understand the goals evolution has "naturally designed" (Thompson 1986) these mechanisms to achieve. The hypothesized drives or instincts underlying most psychological models, often derived from a simplistic understanding of evolutionary theory, are usually simply taken for granted in the development of these models.(ABSTRACT TRUNCATED AT 250 WORDS)

A mathematical model of the self.

I attempt here briefly to sketch a mathematical structure with properties analogous to key features of the self. This structure, while not easy to envision, is nonetheless as plausible a basis for theory as any science requires. I hope in this way to account for some aspects of the self that have long impeded systematic thinking on the subject.

A generalized perceptual space.

Based upon experimental results on certain visual spatial discrimination tasks, we have developed a formalism for a non-Euclidian perceptual space. In this formalism, the transformation from real to perceptual space is given by a generalized covariant tensor. The concept of parallel transport of vectors in a curved space is used to prove that closed loops in real space imply closed loops with the same orientation in the perceptual space also.

Sport participation motivation in young adolescent girls: the role of friendship quality and self-concept.

This study examined the factor structure of the Sport Friendship Quality Scale (SFQS; Weiss and Smith, 1999) and compared two models in which (a) self-worth mediated the relationship between physical self/friendship quality and sport commitment and (b) friendship quality and physical self-perceptions directly predicted self-worth and sport commitment. Female team sport participants (N = 227) between the ages of 11 and 14 years completed measures of sport commitment, enjoyment, athletic competence, physical attractiveness, self-worth, and friendship qualities. A confirmatory factor analysis found an inadequate fit for the SFQS, mainly due to problems with the loyalty and intimacy subscale. Separating the loyalty and intimacy factor into two subscales provided an adequate fit. Examination of the two structural models indicated that both models provided an adequate overall fit but that self-worth only weakly predicted sport commitment, suggesting the mediator model was impractical. Friendship quality had a weak relationship with self-worth and sport commitment. Results are discussed in light of issues in measuring sport friendship quality and future directions in this developing field.

Team-referent attributions among sport performers.

The aim of this study was to develop and validate a team-referent attribution scale. Conducted over three studies, Study 1 modified items from McAuley, Duncan, and Russell's (1992) Causal Dimension Scale II by rewording items to reflect team attributions and adding one item per factor. This led to the development of a 16-item scale (Causal Dimension Scale-T, CDS-T). Study 2 tested competing models of attribution theory among a sample of 433 team sport players. Confirmatory factor analysis indicated strongest support for a four-factor model (robust comparative fit index = .961; root mean squared error of approximation = .054). Study 3 tested the predictive validity of the scale among a sample of 201 team players. Results indicated that winners reported more internal and stable attributions than losers. Further, performances perceived as successful were associated with stable attributions. The results of the study, therefore, suggest that the CDS-T provides a valid measure of team-referent attributions in sport.

Cue interaction effects in causal judgement: an interpretation in terms of the evidential evaluation model.

In judging the extent to which a cue causes an outcome, judgement can be affected by information about other cues that are correlated with the one being judged. These cue interaction effects have usually been interpreted in terms of associative learning processes. I propose that a different model of causal judgement, the evidential evaluation model, offers a viable alternative interpretation of cue interaction phenomena. Under the evidential evaluation model, instances of contingency information are interpreted as evidence, which is confirmatory, disconfirmatory, or irrelevant for the cue being judged. When two cues co-occur in a set of instances the evidential value of the instances for one of them is determined by three factors: the proportion of confirming instances in the set; disambiguation value, which concerns the relation between the set of information and prior beliefs about the co-occurring cue; and confirmation value, which concerns the relation between the set of information and prior beliefs about the cue being judged. Any previous judgement of the cue is then modified in the light of these. It is shown that this model can account for all the cue interaction phenomena that have been investigated in studies of human causal judgement. The model also generates novel predictions, and the results of three experiments give support to these predictions. It is also shown that several other current models of causal judgement fail to predict a key result from Experiment 3.

Residential therapeutic communities in the mainstream: diversity and issues.

Not all residential drug abuse treatment programs are therapeutic communities (TCs), not all TCs are in residential settings, and not all programs that call themselves TCs employ the same social and psychological models of treatment. The term "therapeutic community" is widely used to represent a distinct approach in almost any setting, including community residences, hospital wards, prisons, and homeless shelters. One effect of this labeling has been to cloud understanding of the TC as a drug abuse treatment approach, how well it works, where it works best, and for which clients it is most appropriate. This article attempts to further a general understanding of residential TCs. Distinctions are drawn between residential drug abuse treatment and residential TCs. The diversity of programs within the TC modality is described in terms of modifications of the model and applications to special populations; and the essential elements of the TC program model are briefly outlined. Finally, movement into the mainstream has surfaced issues for the TC in terms of policy and practice, several of which are highlighted.

Investigating the criterion validity of psychiatric symptom scales using surrogate marker validation methodology.

This work investigates whether techniques that are generally used for the validation of surrogate markers in clinical trials can be applied in the validation of psychiatric health measurements (often scales) and more generally to investigate relationships between treatment effects on different measurements. However, the categorical nature of some scales makes these techniques inapplicable in the way they were originally defined. In this work, we show a possible extension of this methodology to the setting in which one of the scales is an ordinal categorical variable. When psychiatric health measurements are either developed or used in a new population, reliability and validity must be investigated. Reliability, more specifically internal consistency, test-retest reliability, and inter-rater reliability, is focused on the reproducibility of the measurement. Validity is defined as the degree to which the scale measures what it purports to measure. This can be performed through the analysis of content, construct, and criterion validity. We argue that recent methodology, in particular developed to study surrogate endpoints, can be used to examine criterion validity, concurrent validity, and predictive validity. In concurrent validity, we correlate the measurement with a criterion measure, both of which are given at the same time. In predictive validity, the criterion will not be available to some point in time in the future. The surrogate methods were applied on pooled data from five trials in schizophrenia.

How can sociological theory help our understanding of addictions?

Those who work in the addiction field usually use the pharmacological or medical model, psychological theories of behavior, or operate within the confines of a criminal justice perspective. Contributions from the field of sociology are limited to use of the methods of sociological investigations, primarily population surveys, which, typically, are used to identify groups at-risk for specific types of drug use. Surveys have identified illicit drug use as, predominantly, a problem of young males, whereas prescription drug use is predominantly a problem of middle-aged and older women in industrialized countries. Experts in addiction have accused sociologists who study addiction of being "atheoretical." Paradoxically, in the sociology field, the most highly cited article is Merton's theory of addiction. This article will examine the contributions of sociological theory to our understanding of addiction, including social definitions of "the problem of addiction" and mechanisms to account for individual drug use within a social context that defines it as problematic.

Bilateral orchiectomy for the surgical treatment of complete androgen insensitivity syndrome: patient outcome after 1 year of follow-up.

OBJECTIVE: To describe an operative approach to bilateral orchiectomy for complete androgen insensitivity syndrome (AIS) and to report patient status 1 year after surgery. MATERIAL AND METHOD: A 19(1/2)-year-old woman with primary amenorrhea, cervical/uterine agenesis, elevated serum testosterone, and 46,XY karyotype underwent characterization of the androgen receptor mutation by polymorphism sequence analysis. Bilateral orchiectomy was performed via a triple-puncture 5-mm laparoscope, and postsurgical hormone replacement followed a daily oral contraceptive model. Psychological counseling was provided to the patient and her family. RESULTS: Minimally invasive removal of the gonads was accomplished without complication. Microscopic examination of the testes revealed a benign Sertoli cell-only pattern. After 1 year, the patient's level of functioning and psychosexual status were unchanged in comparison with before surgery. CONCLUSIONS: Patients with complete AIS should undergo postpubertal gonadectomy because of an increased risk for malignant transformation of the testicles, and this can be performed safely via small-caliber laparoscopy. Attention to psychological considerations in such patients is important to maximize long-term success.

The psychological construction of the Internet: from information foraging to social gathering to cultural mediation.

Psychological models influence both design and use of the Internet. Three models are considered. The first, cognitive, builds the Internet as an environment in which information foraging occurs. This model considers information seeking as an active process, but does take account of cooperation and communication. The second model, social, builds the Internet as a space for people's coming together and communicating. It makes sense of much of what is at present passing in the Internet, but focuses almost exclusively on the interpersonal aspects of electronic communication. The third model, cultural, builds the Internet as a powerful new artifact that requires the formation of appropriate cultural codes to be integrated smoothly with people's everyday experience.

Development and validation of the Amsterdam Motives for Drinking Scale (AMDS): an attempt to distinguish relief and reward drinkers.

UNLABELLED: Determination of alcoholic subtypes is a promising strategy for patient treatment matching with anti-craving interventions. The aim of this study is to develop and validate a questionnaire on drinking motives that can distinguish relief and reward drinkers. METHODS: A 103-item self-report questionnaire was developed: the Amsterdam Motives for Drinking Scale (AMDS). The AMDS was tested in two samples of alcoholics (Sample A: n = 251; Sample B: n = 197). The psychometric properties were examined in Sample A and cross-validated in B. RESULTS: The AMDS consists of a relief scale and a reward scale, both containing distinct subscales. All (sub)scales had good internal consistency. However, the relief and reward scales were highly correlated (Sample A: r = 0.84, P < 0.01; Sample B: r = 0.76, P < 0.01), and convergent and divergent validity was only partly confirmed. The lowest correlations were found between the relief subscale 'stress and vulnerability' and the reward subscale 'stimulation seeking' (Sample A: r = 0.33, P < 0.01; Sample B: r = 0.13, P > 0.01). CONCLUSIONS: The AMDS reliably measures two types of motives. However, the relief and reward scales are highly correlated. Lower correlations were found only at the subscale level. It is concluded that most treatment-seeking alcoholics have both relief and reward motives. More research is needed on the relationship between motives for drinking and other phenotypic, endophenotypic and genetic indicators of relief and reward drinking, and appropriate cut-off points. Only than we can draw firm conclusions regarding the potential of drinking motives for patient treatment matching.

Using a Bayesian latent growth curve model to identify trajectories of positive affect and negative events following myocardial infarction.

Positive and negative affect data are often collected over time in psychiatric care settings, yet no generally accepted means are available to relate these data to useful diagnoses or treatments. Latent class analysis attempts data reduction by classifying subjects into one of K unobserved classes based on observed data. Latent class models have recently been extended to accommodate longitudinally observed data. We extend these approaches in a Bayesian framework to accommodate trajectories of both continuous and discrete data. We consider whether latent class models might be used to distinguish patients on the basis of trajectories of observed affect scores, reported events, and presence or absence of clinical depression.

Theory, explanation, and a third generation of theoretical development in social gerontology.

Efforts at cumulative knowledge building in social gerontology have been lax, judging from research articles published in journals between 1990 and 1994. Too little attention has been paid to the cumulative development of theory; readers are left with many empirical generalizations but underdeveloped explanations by which to interpret findings and build upon them in subsequent research. To assist future theory development in social gerontology, we review seven theoretical perspectives referenced most frequently in recent journals: (1) social constructionist, (2) social exchange, (3) life course, (4) feminist, (5) age stratification (age and society), (6) political economy of aging, and (7) critical theory. We suggest that, taken together, these represent a "third generation" of explanation in social gerontology, noting their debt to older and more established traditions in social science theory. We argue that authors and journal reviewers should place more emphasis on theory development - which means, most simply, the construction of explicit explanations in accounting for empirical findings - if knowledge development about social aspects of aging is to be cumulative, systematic, and incremental.

Adolescent and elderly white male suicide trends: evidence of changing well-being?

This study investigated the relationship proposed by Preston (1984) between suicide trends and the changing status of America's dependent populations. Since World War II, as adolescent suicide rates have risen and elderly suicide rates declined, the rates have generally converged. In particular, adolescent and elderly suicide rates among White males reveal some of the most dramatic shifts relative to other age-race-sex-specific groups. This social-demographic study examined indicators of well-being as proposed by Preston (1984) to determine whether these structural factors can account for White male adolescent and elderly suicide trends. Using annual U.S. suicide rates for the White male populations aged 15 to 24 and 65 and over, I examined the hypotheses that (a) the rising suicide trend among the adolescent population is associated with a deteriorating state of well-being for adolescents, and (b) the generally declining suicide trend among the elderly population is associated with an improving state of well-being for elderly persons. A post-World War II annual time series analysis was used in this research for the period 1946 to 1986. The findings suggest that family dissolution and White children living in poverty are associated with White male adolescent suicide trends and that societal affluence is associated with White male elderly suicide trends. The implications of these findings for future adolescent and elderly suicide trends are also addressed.
