Older women and mammography screening behavior: do possible selves contribute?

This study sought to explore the contribution of the self-concept to older women's adherence to regular mammography screening behavior. The PRECEDE and health belief model concepts were incorporated with a measure of the women's future selves to determine whether the self-concept adds to our ability to predict screening. A self-administered questionnaire was completed by 210 community-dwelling women ages 50 to 75 years, recruited from urban and rural women's groups. Logistic regression analyses revealed that predictors of adherence were clinical breast examination, physician recommendation, age, barriers, benefits, feared health-related possible self, and self-efficacy in the feared domain. The addition of the self measures significantly improved the overall fit of the model. Implications for theory development, practice, and future research are discussed.

An exploratory factor analysis of children's depression inventory scores in young children of substance abusers.

A factor analytic study of scores obtained on the Children's Depression Inventory from a sample of 202 young children (M = 7.5 yr., SD = 2.2) of alcoholics and substance abusers was completed. A principal components factor analysis with an oblique rotation yielded five separate factors related to Negative Self-concept, Acting-out. Somatic/Disturbed Symptoms, Mood, and Hopelessness. In previous factor analytic studies of the Children's Depression Inventory with normal and clinical populations the primary factor obtained was formed by mood-related items. In contrast, the primary factor of the present analysis was formed by items concerning perceptions of self-concept, not mood. These results corroborated previously reported data from the Child Behavior Checklist suggesting that the depressive symptoms displayed by children of substance abusers are related to self-concept and externalization.

Information-seeking and maternal self-definition during the transition to motherhood.

The self-definitional processes accompanying the transition to motherhood were examined in this study. A cross-sectional sample of more than 600 women who were planning to get pregnant within 2 years, pregnant, or in the postpartum stage completed extensive questionnaires pertaining to their experiences of pregnancy and motherhood. On the basis of the assumption of the "self-socialization" perspective that individuals actively construct their identities in response to life transitions, our analyses focused on the role of information-seeking in the developing self-definitions of women becoming mothers. As predicted, (a) women actively sought information in anticipation of a first birth, (b) they used this information to construct identities incorporating motherhood, and (c) after the birth the determinants of their self-definitions shifted from indirect sources of information to direct experiences with child care. Hence, consistent with the self-socialization perspective, information-seeking did play an important role in the women's developing self-conceptions during this life transition. Mechanisms by which information gathered may alter self-conception are discussed.

Self-image resilience and dissonance: the role of affirmational resources.

It was predicted that high self-esteem Ss (HSEs) would rationalize an esteem-threatening decision less than low self-esteem Ss (LSEs), because HSEs presumably had more favorable self-concepts with which to affirm, and thus repair, their overall sense of self-integrity. This prediction was supported in 2 experiments within the "free-choice" dissonance paradigm--one that manipulated self-esteem through personality feedback and the other that varied it through selection of HSEs and LSEs, but only when Ss were made to focus on their self-concepts. A 3rd experiment countered an alternative explanation of the results in terms of mood effects that may have accompanied the experimental manipulations. The results were discussed in terms of the following: (a) their support for a resources theory of individual differences in resilience to self-image threats--an extension of self-affirmation theory, (b) their implications for self-esteem functioning, and (c) their implications for the continuing debate over self-enhancement versus self-consistency motivation.

Adolescent body image during pregnancy.

This study compares the body perceptions of pregnant teenagers with those of their never-pregnant peers. Forty-three third-trimester pregnant girls were matched by age, race, socioeconomic status, and pubertal development to 43 never-pregnant girls. Subjects were given the Tennessee Self-Concept Scale (TSCS), a self-administered questionnaire consisting of 100 self-descriptive statements which are divided into nine subscales. When compared with never-pregnant girls, the pregnant girls have a higher overall self-esteem, a more positive body image, a surer self-identity, and feel more productive as a family member, but appeared limited in their capacity for self-criticism.

[Uniqueness seeking behavior as a self-verification: an alternative approach to the study of uniqueness].

Uniqueness theory explains that extremely high perceived similarity between self and others evokes negative emotional reactions and causes uniqueness seeking behavior. However, the theory conceptualizes similarity so ambiguously that it appears to suffer from low predictive validity. The purpose of the current article is to propose an alternative explanation of uniqueness seeking behavior. It posits that perceived uniqueness deprivation is a threat to self-concepts, and therefore causes self-verification behavior. Two levels of self verification are conceived: one based on personal categorization and the other on social categorization. The present approach regards uniqueness seeking behavior as the personal-level self verification. To test these propositions, a 2 (very high or moderate similarity information) x 2 (with or without outgroup information) x 2 (high or low need for uniqueness) between-subject factorial-design experiment was conducted with 95 university students. Results supported the self-verification approach, and were discussed in terms of effects of uniqueness deprivation, levels of self-categorization, and individual differences in need for uniqueness.

The self-nonself concept as a basis for immune complex to replace "autoimmune diseases".

The remarkable history of the 1951 pp 66 year old woman with gastric adenocarcinoma is reviewed. After subtotal gastrectomy she survived for 22 years without any metastases. Presumably the artificially induced high titer IgG, anti-P1 proved to be cytotoxic in two stages: (1) binding of anti-P1 to the terminal fifth sugar, galactose, and (2) the action of cellular immunity in the form of killer T derived lymphocytes containing receptors for IgG molecules. An identical mechanism may be operative in inducing abortions in the pp pregnant woman with a P1 fetus. P1 illegitimate glycolipid (GL) red cell antigen and Forssman (Fs) tissue in adenocarcinoma suggest the self-nonself concept because these are genetically foreign to the host. This concept applies also to numerous "autoimmune" diseases such as RA, lupus, glomerulonephritis, Coombs positive hemolytic anemia and other diseases with immune complexes (ICs) of 20--22 Svedberg units deposited as lesions with tissue damage. In the presence of the GL antigens (ABO, P, Fs), the normal serum contains antibodies for the missing antigen(s). The predicted anti-Fs was present in about 80% of normal employees of ages 18--70. In cancer sera the incidence was 35--40%. On testing normal sera by age in terms of decades anti-Fs was present in 93% in the youngest, and only 55% in the oldest group. This may be associated with the gradual loss of protein synthesis with aging and/or the accumulation of soluble ICs which bind the C1q portion of the C added to the test mixture of heat-inactivated serum (1 : 8) g.p. C (1 : 30) and srbc. In "autoimmune" diseases there is an active immune response to viral or bacterial infections or infestations or drugs which attach to rbc and/or tissue cell membranes. This results in the deposition in selected organs of ICs of 20--22 S units with lesions and tissue damage. For therapy plasma (from young donors) exchange has been recommended to compensate for the loss of IgG antibodies and C.

[Adult health problems and coping at life turning points].

At important life turning points, middle-aged adults face many physiological changes (e.g., aging, changes in hormone levels) and alterations in family structure (e.g., children growing up and leaving home). In addition to facing these changes and their impacts, adults must also take on challenges in terms of self-concept, body image, life goals, and life meaning. Illnesses that commonly occur during this life stage include menopausal depression, substance abuse, and anxiety. Traditional treatment models are medical-oriented, but curative effects are limited and hospital visits still occur at high frequencies, resulting in increased medical expenses and disruptions in family life. The authors review the current literature on curative models in this area, and discuss the potential of a combination of physical therapy, cognitive, and existential-humanistic therapy to improve patients' physical strength, self-concept, self-esteem, and self-confidence in an effort to overcome physio-psycho-social disorders and to increase vitality.

Onset of insomnia: role of life-stress events.

During the year their insomnia began, chronic insomniacs experienced a greater number of stressful life events compared with previous or subsequent years and compared with good sleepers. In addition, among the life event categories assessed, insomniacs reported a greater number of undesirable events, particularly events related to losses and to ill health. They also had lifelong histories of more illnesses and somatic complaints, beginning with more childhood illnesses and more childhood problems related to eating and sleeping. During childhood, insomniacs reported more frequent discontent with their families, and prior to the onset of insomnia, they had less satisfying relationships with their parents as well as problems in other interpersonal relations and in their self-concepts. Currently, insomniacs felt considerably less satisfied with their lives, had lower self-concepts, and had greater difficulty with interpersonal relationships. Thus, stressful life events, mediated by certain predisposing factors of personal vulnerability, were found to be closely related to the onset of chronic insomnia.

[A study of home care needs of patients at discharge and effects of home care--centered on patients discharged from a rural general hospital].

The study was carried out at W. hospital, an affiliated hospital of Y university, involved a total of 163 patients who were discharged from the hospital between May 1990 and March 1991. Data collection was twice, just prior to discharge and a minimum of three months post discharge. Thirty patients who lived within a hour travel time of the hospital received home care during the three months post discharge. Nursing diagnoses and nursing interventions for these patients were analyzed in this study. The results of the study are summarized as follows: 1. Discharge needs for the subjects of the study were analyzed using Gordon's eleven functional categories and it was found that 48.3% of the total sample had identified nursing needs. Of these, the needs most frequently identified were in the categories of sexuality, 79.3%, health perception, 68.2% self concept, 62.5%, and sleep and rest 62.5%. Looking at the nursing diagnosis that were made for the 30 patients receiving home care, the following diagnoses were the most frequently given; alteration in sexual pattern 79.3%, alterations in health maintenance, 72.6%, alteration in comfort, 68.0%, depression, 64.0%, noncompliance with diet therapy, 63.7%, alteration in self concept, 55.6%, and alteration in sleep pattern, 53%. 2. In looking at the effects of home nursing care as demonstrated by changes in the functional categories over the three month period, it was found that of the 11 functional categories, the need level for health perception, nutrition, activity and self concept decreased slightly over the three month period. On the average sleep patterns improved, but restfulness was slightly less and bowel elimination patterns improved but satisfaction with urinary elimination was slightly less. On the other hand, role enactment, sexuality, stress management and spirituality decreased slightly. The only results that were statistically significant at the 0.05 level were improvement in digestion and decrease in pain. No statistically significant changes were found in ability related to ADL, the total ADL score at discharge was 19.78 +/- 8.23, and after 3 months 19.01 +/- 8.12. Considering that a majority of the patients were over 60 years of age and that many had brain or spinal cord injuries, the fact that their ADL ability did not deteriorate after discharge can be interpreted as related to a positive impact by the home health care nurses. Similarly there was a slight but not statistically significant decrease in the quality of life scores between the two test times (147.83 at discharge and 143.02 at the three month period).(ABSTRACT TRUNCATED AT 400 WORDS)

Synthesis of a self-contained concept of the molecular mechanism of energy interconversion by H(+)-transporting ATP synthase.

The original aim of the review has been to probe into the validity of the paradigm on the high energy-carrier function of ATP. It seemed to be called into question on the basis of findings with H(+)-transporting ATP synthase suggesting the formation of ATP from ADP and Pi without energy input. Thus, ATP appeared as a low-energy compound. Starting from the current, rich knowledge of the molecular structure and the inviting thinking on the mechanism of H(+)-transporting ATP synthase, we have endeavoured to freshly interpret and integrate the pertinent observations in the light of the comprehensively derived model of the molecular mechanism of energy interconversion by Na+/K(+)-transporting ATPase. In this way, we have uncovered the common mechanistic elements of the two energy-interconverting enzymes. The emerging purpose of the present paper has been the 'synthesis' of a self-contained concept of the molecular mechanism of the interconversion of electrochemical and chemical Gibbs energies by H(+)-transporting ATP synthase. The outcome is reflected in the following tentative evaluations. 1. In ATP hydrolysis, the great Gibbs energy change which is observed in solution, is largely conserved by the F1 sector of ATP synthase as mechanical Gibbs energy in the enzyme's protein fabric, so that it can be utilized in the resynthesis of ATP from enzyme-bound ADP and Pi. The plainly measured low Gibbs energy change results from large compensating enthalpy and entropy changes that reflect the underlying changes in protein conformation. 2. In stoichiometric ATP synthesis by F1 sector from ADP and Pi bound to the catalytic centre, their intrinsic binding energy brings about a loss of peptide chain entropy that makes possible an entropy-driven ATP formation. 3. The driving force for ATP synthesis cannot be the high Gibbs energy change on binding of product ATP; the tight ATP-enzyme complex rather is a low Gibbs energy intermediate from which escape is difficult. 4. The catalytic centre exists either in an open state unable to firmly bind the substrate-product couple, or in a closed state protecting formed ATP from facile hydrolysis by ambient water. 5. The cleft closure, induced by binding of Pi and ADP or ATP, does not necessarily need external energy supply, because the cleft closure proceeds from rigid domain rotations which can occur rather spontaneously. In further analogy to adenylate kinase, the driving force of this domain movement presumably comes from the electrostatic interactions between phosphate moieties and arginine side chains in the catalytic centre.(ABSTRACT TRUNCATED AT 400 WORDS)

A psychometric evaluation of a residential treatment facility: an illustration of an interpretable research design without a control group.

This paper reports on the interim results of an evaluation study which followed a group of disordered-delinquent adolescents discharged from a long-term residential treatment program. Findings from the first cohort of adolescents tested at admission and discharge with the Tennessee Self-Concept Scale (TSCS) indicate statistically significant improvement in all the areas of self-concept, significant decreases in all areas of psychopathology, and no systematic response set at either testing. The research design is unique in that, without a control group, competing interpretations of treatment effectiveness have been ruled out. Using design features, clinical observation, and common sense, four competing explanations of the favorable results have been eliminated. Both the instrument and research design are of interest to those undertaking evaluation research in underfunded settings where control groups are difficult to obtain due to financial or logistical problems.

A play-focused intervention involving mothers of preschoolers.

OBJECTIVES: This study examined the effect of an occupational therapy intervention program for mothers of preschoolers. It was designed to enhance mother-child interaction through play, reduce mothers' perceived stress, and increase mothers' knowledge about child development. METHOD: Maternal causal attributions for parent-child interaction outcomes, stress, self-concept as educator, and children's temperament and behavior were measured with standardized questionnaires before, after, and at 18 months follow-up to the intervention program. The intervention comprised a 2.5-hr, 10-week activity-based program that involved 35 mothers and their 2-year-old to 3.5-year-old children in toy making and toy demonstrations. Subjects were assigned to two intervention program (experimental) groups and one control group, which was administered questionnaires but whose members did not attend a program. RESULTS: No group changes were detected on conclusion of, or follow-up to, the program according to measures of attributions for parent-child interaction outcomes, perceived stress, self-concept as educator, or child temperament and behavior. However, some subjects had substantial score increases in their self-concept as educators of their children. Subjects' evaluations for each session and the overall program were positive. Feedback from community nurses confirmed that several subjects subsequently used the skills they had learned through the intervention about use of toys and child development to conduct playgroups in the community. Previously undetected developmental or behavioral problems were identified for 8 (23%) of the 35 subjects. CONCLUSION: Subjects' positive responses to the program, the skills they acquired and shared, and identification of problems needing treatment supported the value of the intervention. Lack of quantifiable group changes suggested that qualitative, single-case design evaluations, or both may have been more appropriate methods to assess outcomes.

Constructing desirable identities--self-presentation in psychotherapy and daily life: comment on Kelly (2000)

A. E. Kelly's (2000) thesis that psychotherapy clients benefit from withholding negative information is considered in light of current social-psychological theory and research. Positive illusions about oneself are associated with indexes of mental health; this is consistent with treating therapy as positive identity development. Self-presentation can shape self-concept, even apart from the feedback that an audience might provide; the social construction of identity is a powerful process, suggesting that withholding negative and presenting only positive information is adaptive. However, evidence concerning the level of identification of one's actions suggests complexities in understanding ways clients might deal with disclosing negative information; the authors argue that the impact on self-concept is probably more complex than A. E. Kelly's characterization and that the implications are of a broader scope than indicated so far.

A mediational model of quality of life for individuals with severe mental health problems.

BACKGROUND: Despite the increasing importance of quality of life in the mental health field, the theoretical conceptualization of the construct remains poorly developed. A proposed mediational model of quality of life, which links subjective quality of life with self-related constructs, is examined with a group of long-term psychiatric hostel residents. The present study aims to develop a measure of quality of life based on the proposed model, to explore the data and their implications for service development and finally to conduct a preliminary analysis of the model's predictions. METHODS: A cross-sectional research design was employed. Quality of life interviews, using a modified version of Lehman's Quality of Life Interview, were carried out with 54 psychiatric residents in Greece. The model's predictions were examined by using a series of regression analyses. RESULTS: The results indicate that perceived improvements in lifestyle, greater autonomy and positive self-concept are significantly and directly associated with better quality of life. In contrast, a direct relationship between objective indicators and subjective quality of life was not found. CONCLUSIONS: The traditional two-part quality of life model that includes objective indicators of life circumstances and subjective indicators is extended to included the constructs of self-concept and perceived autonomy. The present extended mediational model of quality of life for individuals with long-term mental health problems appears to have important implications for the planning and delivery of mental health programmes.

Cognitive and emotional outcome after pediatric liver transplantation.

The aim of the study was to evaluate the cognitive and emotional development after pediatric liver transplantation. A total of 21 patients, aged 4-16.9 yr (median 9.6 yr) were tested 1-9 yr (median 4.2 yr) after the transplantation. The pretransplant diagnoses included biliary atresia (eight patients), various metabolic diseases (n = 6), acute liver failure (n = 3), and miscellaneous (n = 4). The cognitive functions were tested with Wechsler preschool and primary scale of intelligence (WPPSI)-R or Wechsler intelligence scale for children (WISC)-III according to age. The Piers-Harris self-concept scale and the evaluation of human figure drawings according to Koppitz were used to detect emotional problems. All tests in all patients were performed by the same psychologist. A significantly lower result on cognitive tests was seen when compared with the expected normal values (p < 0.01). The number of patients with results within or under the lower normal range was higher than expected. Although the mean value of the Piers-Harris self-concept scale was normal, there was a large spread within the group. Indicators of emotional problems were found in the human figure drawings of 50% of the patients. To some extent, low cognitive scores coincided with low scores on self-concept scale and indicators of emotional difficulties. We conclude that the high degree of cognitive and emotional problems after liver transplantation is an important argument for routine psychologic follow-up and support in these patients.

The liberating effects of RN-to-BSN education.

This study investigated whether postlicensure baccalaureate education was associated with decreased acceptance of oppressed status for nursing and the self, with behavioral changes in job performance, and in joining a professional organization. Selected writings of Freire (1970a, 1970b, 1973) concerning education of the oppressed were used to form the conceptual framework. Baccalaureate education was conceptualized as a means of overcoming oppression-related behaviors and attitudes in nurses. The criterion measures were self-reports of job performance, joining the American Nurses Association (ANA), self-concept measurements, and perception of nursing measured by a semantic differential. Except for self-concept, which remained unchanged, all the findings were in the predicted direction supporting the conceptual framework.

Development and construct validity of a self-description inventory for African adolescents.

The present study presents evidence for the reliability and validity of a new measure of self-concept for African adolescents. Procedures for giving the 50-item scale are described. The Self-description Inventory was administered to 634 students in Standards 8 and 9 of two coeducational high schools. Factor analysis clearly identified the eight subscales. The multidimensionality of self-concept among African adolescents is indicated and supports the construct validity. Implications for continued study are mentioned.
