Coping styles associated with psychological adjustment to advanced breast cancer.

The aim of this study was to determine whether psychological adjustment to advanced breast cancer was positively associated with expressing emotion and adopting a fighting spirit and negatively associated with denial and fatalism. Total mood disturbance on the Profile of Mood States was used as the measure of psychological adjustment. The Courtauld Emotional Control Scale measured emotional expression, and the Mental Adjustment to Cancer measured fighting spirit, denial, and fatalism. The sample included 101 women with a diagnosis of metastatic or recurrent breast cancer. Fighting spirit and emotional expressiveness were found to be associated with better adjustment. No association was found between mood disturbance and denial or fatalism. Because this was a cross-sectional study, no conclusions regarding a causal relationship between adjustment and emotional expressiveness or adjustment and fighting spirit were possible.

Sexual abuse history and associated multiple risk behavior in adolescent runaways.

Relationships between sexual abuse and sexual risk, substance use, emotional distress, and conduct problems were examined among 190 runaways. Those who had been abused were significantly more likely than nonabused peers to engage in unprotected sex, have more sexual partners, and use alcohol and drugs, but did not differ in emotional distress. Those abused after age 13 were more often engaged in sex work than nonabused peers. Males abused before age 13 had more sexual partners than those not abused, and runaway males were significantly more likely to have been sexually abused than has been reported in prior research.

Hypnotizability and traumatic experience: a diathesis-stress model of dissociative symptomatology.

OBJECTIVE: The authors propose a diathesis-stress model to describe how pathological dissociation may arise from an interaction between innate hypnotizability and traumatic experience. METHOD: To support the proposition that pathological dissociation may reflect autohypnotic process, the authors highlight clinical and research data indicating parallels between controlled hypnotic dissociative states and uncontrolled pathological dissociative symptoms and summarize evidence of hypnotizability in persons with psychiatric disorders that manifest these symptoms. The authors present this evidence by examining dissociative symptomatology in four psychological domains: perception, behavior and will, affect, and memory and identity. In addition, modern cognitive and neuropsychological models of dissociation are briefly reviewed. RESULTS: Several lines of evidence converge in support of the role of autohypnosis in pathological dissociation. There is considerable evidence that controlled formal hypnosis can produce a variety of dissociations of awareness and control that resemble many of the symptoms in uncontrolled pathological dissociative conditions; and it is possible to discern in dissociative pathology the features of absorption, dissociation, and suggestibility/automaticity that characterize formal hypnotic states. There is also accumulating evidence of high levels of hypnotic capacity in all groups with dissociative symptomatology that have been systematically assessed. In addition, the widespread and successful therapeutic use of hypnosis in the treatment of many dissociative symptoms and conditions (and the potential for hypnosis to induce dissociative symptomatology) also supports the assumption that hypnosis and pathological dissociation share an underlying process. CONCLUSIONS: High hypnotizability may be a diathesis for pathological dissociative states, particularly under conditions of acute traumatic stress.

When disaster strikes, acute stress disorder may follow.

During and immediately following a traumatic event, people may manifest a pattern of dissociative and anxiety symptoms and other reactions, referred to as Acute Stress Disorder. A review of the empirical literature on psychological reactions to trauma suggest that this pattern of symptoms has often been identified across different kinds of traumatic events. It is likely to constitute a psychological adaptation to a stressful event, limiting painful thoughts and feelings associated with the event and allowing the person to function at least minimally. Continuation of these symptoms, however, may impair the person's quality of life and disrupt social and other functioning. If symptoms last beyond a month following the traumatic event, Post Traumatic Stress Disorder (PTSD) may ensue, continuing for months or even years after the precipitating event. Hence, it is important to be able to identify this pattern of reactions that may be manifested in reaction to trauma, so that appropriate intervention can be provided. Although it was not officially recognized in the 3rd edition Diagnostic and Statistical Manual (DSM-III-R), Acute Stress Disorder is included as a separate diagnosis in the DSM-IV.

Prevalence of HIV-related risk behaviors and STDs among incarcerated adolescents.

PURPOSE: To determine the HIV-related risk behaviors and STDs in a population of incarcerated adolescents in order to strategically target education and prevention efforts. METHODS: A single point-in-time prevalence study based on an analysis of intake medical records of 1,215 incarcerated youth were analyzed for HIV risk behaviors and STD history. RESULTS: Incarcerated adolescents report high rates of risk behaviors for HIV infection and STDs, with 75% reporting three or more sex partners, 25% never using condoms and 19% having a current diagnosis of at least one STD. Significantly more females than males reported a history of STDs and had higher rates of current diagnoses of chlamydia/non-gonococcal urethritis, trichomonas and gonorrhea. CONCLUSIONS: Ethnic/racial and gender differences were found in risk behaviors for STDs among a sample of incarcerated adolescents.

Predicting patterns of sexual acts among homosexual and bisexual youths.

OBJECTIVE: This longitudinal study examined predictors of patterns of change in HIV sexual risk acts among homosexual and bisexual adolescent males. METHOD: A consecutive series of 136 homosexual and bisexual males aged 14-19 years were recruited into the study. Subjects were predominantly Hispanic (51%) and African American (31%) and seeking services at a homosexual-identified community-based agency in New York City. All subjects participated in an intensive HIV intervention program. Patterns of change in HIV sexual risk acts were based on assessments at four points (intake and 3, 6, and 12 months later) and were used to classify youths as demonstrating one of five patterns of anal and oral sexual acts: protected (anal: 45%, oral: 25%), improved (32% and 28%, respectively), relapse (5% and 8%), variable (8% and 15%), and unprotected (10% and 24%). Components of the health belief, self-efficacy, peer influence, coping, and distress models were assessed as predictors of these patterns. RESULTS: Protected and improved patterns of sexual risk acts were associated with low levels of anxiety, depression, and substance use and high self-esteem. CONCLUSIONS: These data suggest that HIV interventions must address non-HIV-related issues confronting youths in difficult life circumstances, particularly emotional distress and the role of peer networks for homosexual and bisexual youths.

Pain and depression in patients with cancer.

BACKGROUND: Although the existence of a relationship between depression and pain in patients with cancer has been known for many years, the influence of one upon the other is still poorly understood. It has been thought that depressed individuals complain of pain more because of their psychiatric illness. Evidence from two studies indicate that pain may induce clinical depression. METHODS: In the first study, the authors examined both current and lifetime psychiatric diagnoses among patients with cancer who had high and low pain symptoms to examine the strength of the relationship between depression and cancer pain. The sample consisted of 72 women and 24 men, with 39 women and 9 men in the high pain group, and 33 women and 15 men in the low pain group. In the second study, 35 patients with metastatic carcinoma of the breast were examined for pain intensity and frequency and mood disturbance. RESULTS: The prevalence of depressive disorders of all types was found to be significantly higher in the high pain than in the low pain group across measures, 33 versus 13% (chi-square [degrees of freedom = 1] = 5.90, P < 0.05). Furthermore, there was a significantly higher history of major depression in the low pain group than in the high pain group (chi-square [degrees of freedom = 1] = 3.86, P < 0.05). Also, in comparison with patients in the low pain group, patients in the high pain group were significantly more anxious and emotionally distressed. In the second study, pain intensity correlated significantly with fatigue, vigor, and total mood disturbance, and pain frequency correlated significantly with fatigue, vigor, and depression. CONCLUSIONS: This study confirms the high concomitant occurrence of pain and psychiatric morbidity and suggests that pain may play a causal role in producing depression.

Predictors of posttraumatic stress symptoms among survivors of the Oakland/Berkeley, Calif., firestorm.

OBJECTIVE: The purpose of this study was to examine factors predicting the development of posttraumatic stress symptoms after a traumatic event, the 1991 Oakland/Berkeley firestorm. The major predictive factors of interest were dissociative, anxiety, and loss of personal autonomy symptoms reported in the immediate aftermath of the fire; contact with the fire; and life stressors before and after the fire. METHOD: Subjects were recruited from several sources so that they would vary in their extent of contact with the fire. Of 187 participants who completed self-report measures about their experiences in the aftermath of the firestorm, 154 completed a follow-up assessment. Of these 154 subjects, 97% completed the follow-up questionnaires 7-9 months after the fire. The questionnaires included measures of posttraumatic stress and life events since the fire. RESULTS: Dissociative and loss of personal autonomy symptoms experienced in the fire's immediate aftermath, as well as stressful life experiences occurring later, significantly predicted posttraumatic stress symptoms measured 7-9 months after the firestorm by a civilian version of the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder and the Impact of Event Scale. Dissociative symptoms more strongly predicted posttraumatic symptoms than did anxiety and loss of personal autonomy symptoms. Intrusive thinking differs from other kinds of posttraumatic symptoms in being related directly to the trauma and previous stressful life events. CONCLUSIONS: These findings suggest that dissociative symptoms experienced in the immediate aftermath of a traumatic experience and subsequent stressful experiences are indicative of risk for the later development of posttraumatic stress symptoms. Such measures may be useful as screening procedures for identifying those most likely to need clinical care to help them work through their reactions to the traumatic event and to subsequent stressful experiences.

Dissociative symptoms in media eyewitnesses of an execution.

OBJECTIVE: The first execution in California since 1976 took place recently in the San Quentin Prison gas chamber. Eighteen journalists were invited as media eyewitnesses. The authors postulated that witnessing this execution was psychologically traumatic and that dissociative and anxiety symptoms would be experienced by the journalists. METHOD: To investigate the prevalence and specific nature of these symptoms, questionnaires were sent to all the journalists about a month after the execution. The questionnaire contained 17 items assessing dissociative symptoms from the authors' questionnaire of 35 highly intercorrelated acute stress items. Fifteen of 18 of the witnesses returned the questionnaire. Items were endorsed on a scale of 0 ("have not experienced") to 5 ("very often experienced") and analyzed as being dichotomously present or absent. The mean age of the respondents was 37.6 (SD = 8.6) and mean years as a journalist were 15.2 (SD = 9.0). Nine subjects were men and six were women. RESULTS: Journalists witnessing the execution endorsed an average of 5.0 dissociative items, ranging from "I saw, heard, or felt things that were not really there" (endorsed by no one) to "I felt estranged or detached from other people" (endorsed by 60%). This prevalence of reported dissociative symptoms is comparable to that seen among persons who endured the recent Oakland/Berkeley, Calif., firestorm. CONCLUSIONS: The experience of being an eyewitness to an execution was associated with the development of dissociative symptoms in several journalists.

Trauma and dissociation.

The stress associated with experiencing or witnessing physical trauma can cause abrupt and marked alterations in mental state, including anxiety and transient dissociative symptoms. Intense manifestations of this pattern of response to trauma are described in a new diagnostic category proposed for DSM-IV: acute stress disorder. Severe dissociative symptoms may predict subsequent posttraumatic stress disorder. Persons who experience a series of traumatic events may be especially vulnerable to a variety of dissociative states, including amnesia, fugue, depersonalization, and multiple personality disorder. Treatment for these symptoms emphasizes strengthening supportive interpersonal relationships and developing insight that reduces psychological pain by integrating the trauma into a meaningful, less self-blaming perspective.

Beliefs and behavioral intentions regarding human immunodeficiency virus testing among New York City runaways.

From 1988 to 1991, 139 runaways aged 11-19 years in the New York City area (n = 70 males, 69 females) were recruited from four shelters. Each runaway participated in a semistructured interview assessing beliefs and behavioral intentions regarding human immunodeficiency virus (HIV) testing. When asked how they would respond to being seropositive for HIV, 29% of runaways reported that they would engage in self-destructive acts and/or harm others (e.g., suicide, unprotected sex), 80% anticipated extreme distress, 47% expected difficulty securing housing and food, and 61% believed that friends were likely to avoid them. When presented with specific alternatives, fewer runaways anticipated self-destructive acts. Drug use, rather than sexual behaviors, would lead runaways to get tested for HIV. These results suggest that health-care providers must anticipate emotional distress and potential self-destructive behavior following receipt of documentation of HIV positive serostatus among runaways. Furthermore, prior to testing, youths' access to food, shelter, medical care, and social support must be secured.

Lifetime sexual behaviors among predominantly minority male runaways and gay/bisexual adolescents in New York City.

Lifetime sexual behaviors were examined among two samples of predominantly minority, male adolescents in New York City aged 12 to 18 (M = 16.3), believed to be at high risk for HIV infection: 59 runaway males in two residential shelters and 60 males attending a community agency (HMI) for gay and bisexual youths. Interviews regarding psychosexual milestones indicated that 93% of these youths had engaged in oral, anal or vaginal intercourse and/or anilingus, with a median of 11.0 female partners among runaway males and a median of 7.0 male partners among HMI males. Both groups initiated sexual activity at a relatively early mean age of 12.6 years. Each group reported a unique developmental sequence of psychosexual milestones. Consistent condom use was reported by 13% of the youths. One quarter of the youths reported involvement in prostitution. These findings detail the need for AIDS prevention programs for these youths.

Reducing HIV sexual risk behaviors among runaway adolescents.

OBJECTIVE: Reductions in runaways' sexual risk behaviors were evaluated in response to an intensive program to prevent human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS). DESIGN: In a nonrandomized control trial, sexual risk behaviors among 78 runaways at one residential shelter who received up to 30 HIV/AIDS intervention sessions were compared with 67 runaways at a nonintervention shelter with sexual behaviors assessed at baseline and 3 and 6 months. SETTING: Runaways were recruited from the only two publicly funded shelters in New York, NY. PARTICIPANTS: The runaways were aged 11 to 18 years, 64% female, and predominantly black or Hispanic. INTERVENTION: The intervention addressed general knowledge about HIV/AIDS, coping skills, access to health care and other resources, and individual barriers to safer sex. MAIN OUTCOME MEASURES: Consistent condom use, a high-risk pattern of sexual behavior, and sexual abstinence over a 3-month time frame were assessed. MAIN RESULTS: As the number of intervention sessions increased, runaways' reports of consistent condom use increased significantly (at 3 months, unique R2 = .06, P less than .05; at 6 months, unique R2 = .09, P less than .05), and their reports of engaging in a high-risk pattern of sexual behavior decreased significantly (at 3 months, unique R2 = .03, P = .06; at 6 months, unique R2 = .04, P less than .05). Abstinence did not change. CONCLUSIONS: The demonstrated effectiveness of the intensive HIV/AIDS program highlights the importance of enlarging the scope of most current HIV/AIDS prevention programs.

AIDS knowledge and beliefs, and sexual behavior of sexually delinquent and non-delinquent (runaway) adolescents.

This study assessed general knowledge of AIDS, beliefs about preventing AIDS, and sexual behavior among two groups of male adolescents at high risk of HIV/AIDS: 60 sexually delinquent males and 57 non-delinquent runaway males. Significantly fewer sexually delinquent than non-delinquent (runaway) males had experienced sexual intercourse with a consenting female partner (45 vs. 89 per cent). Sexually delinquent youths scored significantly lower than non-delinquent youths in general knowledge of AIDS (65 vs. 73 per cent) and were not able to discriminate safer behaviors from those which were less safe (42 vs. 71 per cent). Both groups reported moderate support for beliefs about preventing AIDS. These results suggest HIV/AIDS prevention programs that attempt to increase knowledge are needed by these youths, particularly for sexually delinquent youths.

Homeless youths and HIV infection.

Risk of human immunodeficiency virus (HIV) infection exacerbates the already difficult lives of 1.5 million homeless adolescents in the United States. Homeless youths engage in sexual and substance-abuse behaviors that place them at increased risk of contracting HIV, and they demonstrate other problem behaviors that reduce their coping responses. Model HIV prevention programs and interventions for HIV-positive youths, implemented for homeless adolescents, need to be disseminated on a national level. Social policies must recognize adolescents' rights to satisfaction of basic survival needs; comprehensively address the needs of dysfunctional, disenfranchised, and single-parent families; and provide continuity of care for adolescents to facilitate independent living. Special provisions must be made when designing programs for gay, sexually abused, and substance-abusing youths.

Sexual risk behaviors, AIDS knowledge, and beliefs about AIDS among runaways.

Sexual risk behaviors, knowledge of acquired immunodeficiency syndrome (AIDS), and beliefs about AIDS prevention were examined among 126 runaways. In the previous 3 months, 65 percent of youths had been sexually active. Among the sexually active runaways, males reported a median of 2.7 partners and females reported 1.3 partners, and only 18 percent reported consistent condom use. Runaways demonstrated moderately high AIDS knowledge and beliefs endorsing AIDS prevention. Condom use and abstinence were directly related to beliefs about preventing AIDS.

Sexual risk behavior, AIDS knowledge, and beliefs about AIDS among predominantly minority gay and bisexual male adolescents.

Current sexual risk behavior, AIDS knowledge, and beliefs about AIDS prevention were examined among 59 black and Hispanic male adolescents attending a community center for gay and lesbian youth. Most (73%) were sexually active in the last 3 months, with a median of 2.0 partners and with only 21% reporting consistent condom use. These youths demonstrated moderately high AIDS knowledge (82%) and positive beliefs endorsing AIDS prevention (71%). When risk pattern was defined on the basis of partners, risk acts, and condom use, positive AIDS prevention beliefs were significantly and inversely associated with the high-risk pattern, but not with abstinence. These results suggest that youths who frequently engage in high-risk acts need intervention targeting changes in beliefs and behavior, as well as knowledge.

The nature of patients' requests for physicians' help.

This report describes patients' requests for help in two outpatient settings--one, a general medicine practice (GMP); the other, a medical walk-in unit (WIU). Interview data were collected in 1981 from 200 patients prior to their visits with the doctor. Patients were asked, "How do you hope the doctor (or clinic) can be of help to you today?" Their responses were written down verbatim. A coding system was devised that described the specificity, focus, and form of each request in order to provide the clinician with a classification for recognizing these request elements and responding to them. Specificity (precision) was identified from the response to "What do you hope the doctor will do for you?" The focus (objective) was described by four categories: problem, treatment, relationship, and administration; the form (intervention), by five categories: somatic, cognitive, affective, advice, and instrumental. Patterns of requests differed in the two settings. In the WIU, the pattern of requests had a problem focus with a form split between the cognitive (wanting an explanation) and the somatic (wanting a medical procedure); in the GMP, treatment was the focus, with a somatic form. The overall results indicate the varied requests of medical outpatients that express their perspectives about their illnesses. This classification of requests should be useful to physicians in eliciting and responding to their patients' requests.
