A decade of research and services for homeless mentally ill persons. Where do we stand?

Over the past decade, researchers have documented the range of needs and devised new methods for increasing our understanding of the homeless severely mentally ill population. Clinicians have developed an appreciation of the difficulty and complexity of effectively treating this population, and policymakers have become increasingly aware of the barriers to developing services and housing. In this article, the progress-to-date in research, the evolution of new service approaches, and the development of federal, state, and local policies to meet the needs of homeless mentally ill individuals are assessed. The many challenges that remain are also considered.     

Areas of concern and sources of advice for Israeli adolescents.

This study explored the concerns of Israeli adolescents, who grow up in a socially, politically, and economically highly stressed environment. Ninth- and eleventh-grade students (N = 1,645) completed a questionnaire in which they indicated three important problems they had recently experienced. Content analysis identified six major categories of concerns (listed in descending order of occurrence): studies and career, social "I," personal "I," existential issues, army or national service, and health and drugs. Younger adolescents were found to be more concerned with problems involving studies and career and with issues pertaining to the social "I"; older adolescents were more concerned with existential issues and army or national service. Boys were more concerned with existential issues, army or national service, studies and career, and the social "I." Girls were more concerned with issues pertaining to the personal "I." Three major sources of advice were identified: friends, parents, and brothers/sisters.     

Family origins of adolescent self-criticism and its continuity into adulthood

We used a prospective longitudinal design to examine the relation between parenting experiences at age 5 and level of self-criticism at age 12 and the stability of self-criticism from age 12 to age 31 in 156 subjects. The results showed that mothers' reports of parenting behaviors that reflect restrictiveness and rejection were related to the development of self-criticism, particularly when received from the same-sex parent. Partial correlational analyses revealed that the parenting-self-criticism relations remained significant when the mother's report of the child's early temperament was statistically controlled. The results also showed that for women, self-criticism was very stable from early adolescence to young adulthood. By contrast, there was no relation between self-criticism at ages 12 and 31 for men; however, there was a strong relation for men between age 12 self-criticism and inhibited aggressive impulses at age 31.     

Antidepressants in group psychotherapy

This article alerts us to consider depression as a relatively frequent cause of impasse in the course of group psychotherapy. The authors recommend the combined use of antidepressant medication along with group psychotherapy when such depression is confirmed independently outside the group. Common obstacles and pitfalls preventing successful combined treatment are reviewed; the depressive logjam is differentiated from common resistance; and profiles of responders versus nonresponders are described. A rationale of the combined treatment, its results, and implications for group therapists are all delineated.     

Processing of threat-related information in rape victims

We investigated selective processing of threat information in persons with posttraumatic stress disorder (PTSD) by using a modified Stroop procedure. Subjects were 15 rape victims with PTSD, 13 rape victims without the disorder, and 16 nontraumatized control subjects. They were asked to name the color of four types of words: specific threat (rape-related) words, general threat (related to physical harm and death) words, neutral words, and nonwords. Rape victims with PTSD evidenced a longer response latency for color naming of rape-related words than for other target-word types. Response latencies of non-PTSD victims and nonvictim control subjects did not differ across word types. Possible mechanisms underlying the selective processing of threat material are considered, and clinical implications are discussed.     

A theory of visual interpolation in object perception

We describe a new theory explaining the perception of partly occluded objects and illusory figures, from both static and kinematic information, in a unified framework. Three ideas guide our approach. First, perception of partly occluded objects, perception of illusory figures, and some other object perception phenomena derive from a single boundary interpolation process. These phenomena differ only in respects that are not part of the unit formation process, such as the depth placement of units formed. Second, unit formation from static and kinematic information can be treated in the same general framework. Third, spatial and spatiotemporal discontinuities in the boundaries of optically projected areas are fundamental to the unit formation process. Consistent with these ideas, we develop a detailed theory of unit formation that accounts for most cases of boundary perception in the absence of local physical specification. According to this theory, discontinuities in the first derivative of projected edges are initiating conditions for unit formation. A formal notion of relatability is defined, specifying which physically given edges leading into discontinuities can be connected to others by interpolated edges. Intuitively, relatability requires that two edges be connectable by a smooth, monotonic curve. The roots of the discontinuity and relatability notions in ecological constraints on object perception are discussed. Finally, we elaborate our approach by discussing related issues, some new phenomena, connections to other approaches, and issues for future research.     

Coping within couples: adjustment two years after forced geographic relocation

Is our understanding of how individuals adjust to stressful life events increased when we analyze their adjustment in ways that recognize that these individuals are also married couples? The data used to answer this question came from a unique “natural experiment” occasioned by the forced evacuation of the Israeli settlement of Ophira under the terms of the Camp David Accords. We found that the adjustment of individuals within couples became more similar across the relocation, that is, couples adapted as a “family system.” This occurred because the coping skills of one member of the couple “drove” the adjustment of both partners.     

Learning the invariants of a perceptual motor skill

The concept of invariant relative timing has typically been associated with the concept of a generalized motor programme. The present study approaches the phenomenon of invariant relative timing from the perspective of learning. The underlying question of concern for this study was, "What is learned." The specific question was whether relative timing is one of the essential properties of movement that is learned during skill acquisition. In the present experiment, subjects were given extensive practice in learning to track and reproduce a criterion waveform using a joystick control for their response. In order to test whether subjects learn the relative timing of a movement, they were transferred to tracking waveforms that were identical to the criterion in terms of relative timing, but different in terms of absolute timing. Measurements were taken on all waveforms in two conditions: (a) in a pursuit tracking condition where subjects were temporally constrained by the stimulus, and (b) in a reproduction condition where subjects' timing was not constrained. The outcome from both conditions gives support to the idea that humans learn invariant relative timing during the acquisition of a motor skill.     

Manifestations, acquisition and diagnostic categories of dental fear in a self-referred population

This study aimed to clarify how manifestations and acquisition relate to diagnostic categories of dental fear in a population of self-referred dental fear patients, since diagnostic criteria specifically related to dental fear have not been validated. DSM III-R diagnostic criteria for phobias were used to compare with four existing dental fear diagnostic categories, referred to as the Seattle system. Subjects were 208 persons with dental fear who were telephone interviewed, of whom a subsample of 155 responded to a mailed Dental Anxiety Scale (DAS), State-Trait Anxiety Inventory and a modified FSS-II Geer Fear Scale (GFS). Personal interviews and a Dental Beliefs Scale of perceived trust and social interaction with dentists were also used to evaluate a subsample of 80 patients selected by sex and high dental fear. Results showed that the majority of the 80 patients (66%), suffered from social embarrassment about their dental fear problem and their inability to do something about it. The largest cause of their fear (84%) was reported to be traumatic dental experiences, especially in childhood (70%). A minority of patients (16%) could not isolate traumatic experiences and had a history of general fearfulness or anxiety. Analysis of GFS data for the 155 subjects showed that fear of snakes and injuries were highest among women; heights and injections among men. Fear of blood was rarely reported. Spearman correlations between GFS individual items and DAS scores indicated functional independence between dental fear and common fears such as blood, injections and enclosures in most cases. Only in specific types of dental fear did these results support Rachman and Lopatka's contention that fears are thought to summate.(ABSTRACT TRUNCATED AT 250 WORDS)
