Investigating the influence of achievement on self-concept using an intra-class design and a comparison of the PASS and SDQ-1 self-concept tests

Background. The formation and measurement of self-concept were the foci of this research. Aims. The study aimed to investigate the influence of achievement on academic self-concept and to compare the Perception of Ability Scale for Students (PASS, Boersma & Chapman, 1992) with the Self-Description Questionnaire-1 (SDQ-1, Marsh, 1988). Sample. The participants were 479 grade 5 (mean age 126.6 months) coeducational Australian students, located in 18 schools. Method. An intra-class research design was used to investigate the influence of frame-of-reference on self-concept development. Results. As students' academic scores rose above their class mean their self-concepts increased and as students' academic scores fell below their class mean their self-concepts decreased. Students' difference from class mean predicted their self-concept scores. This finding was consistently shown across the reading, spelling, and mathematics domains using test and teaching rating data. A comparison between the PASS and the SDQ-1 demonstrated concurrent validity across self-concept domains. Conclusion. The findings support the notions that the social environment is a significant agent that influences self-concept, and that teacher ratings and standardised tests of achievement and the PASS and the SDQ-1 are valid measures for self-concept research.

Deficits on self ordered tasks associated with hyperostosis frontalis interna

A 74 year old patient, EW, with dorsolateral frontal cortical compression due to hyperostosis frontalis interna, in the absence of the Morgagni or Stewart-Morel syndromes, is described. In addition to conventional neuropsychological measures EW was administered one nonspatial and two spatial self ordered working memory tasks, as well as a standard measure of fluid intelligence or g. She showed impaired performance on all three self ordered working memory tasks compared with a normal control group of 10 subjects matched for age, education, sex, and IQ. By contrast, her performance on the fluid intelligence test was comparable with that of the controls. It is concluded that the compression of dorsolateral frontal cortex accompanying hyperostosis frontalis interna may produce selective cognitive impairment.

Self-Directed Behavioral Family Intervention for Parents of Oppositional Children in Rural and Remote Areas

Twenty-four parents of oppositional preschoolers were randomly assigned to either a self-directed behavioral family intervention condition (SD) or to a waitlist control group (WL). The self-directed parent training program based on self-regulation principles, consisted of a written information package and weekly telephone consultations for 10 weeks. At posttest, in comparison to the WL group, children in the SD group had lower levels of behavior problems on parent report measures of child behavior. At posttreatment, parents in the SD condition reported increased levels of parenting competence and lower levels of dysfunctional parenting practices as compared to parents in the WL condition. In addition, mothers reported lower levels of anxiety, depression, and stress as compared to mothers in the WL condition at posttreatment. Using mother's reports, gains in child behavior and parenting practices achieved at posttreatment were maintained at 4-month follow-up.

How can and do Australian doctors promote physical activity?

Background. Physical inactivity is recognized as an important public health issue. Yet little is known about doctors' knowledge, attitude, skills, and resources specifically relating to the promotion of physical activity. Our survey assessed the current practice, perceived desirable practice, confidence, and barriers related to the promotion of physical activity in family practice, Methods. A questionnaire was developed and distributed to all 1,228 family practitioners in Perth, Western Australia. Results. We received a 71% response (n = 789). Family practitioners are most likely to recommend walking to sedentary adults to improve fitness and they are aware of the major barriers to patients participating in physical activity. Doctors are less confident at providing specific advice on exercise and may require further skills, knowledge, and experience, Although they promote exercise to patients through verbal advice in the consultation, few use written materials or referral systems, Conclusions. There are significant differences between self-reports of current practice and perceived desirable practice in the promotion of physical activity by doctors, Future strategies need to address the self-efficacy of family physicians and involve resources of proven effectiveness. The potential of referral systems for supporting efforts to increase physical activity by Australians should be explored. (C) 1997 Academic Press.

The personal constructs of coping with chronic low back pain: is coping a necessary evil?

The construct of coping is explored in this paper utilising repertory grid technique with a small group of non-patients with chronic pain. Nineteen volunteers with low back pain completed a repertory grid with eight given elements signifying various self and illness-related roles. Two constructs were given and the remainder elicited using the triad method. The 19 participants rated themselves as being in less pain than those they typified as ill or disabled and considered themselves to be coping with their pain. The constructs elicited emphasised authenticity, the limitations of being a coper, mastery, active stoicism, cheerfulness, acceptance and maintaining acceptable social interactions and appearances. Copers were considered to not be in constant pain. Self, ideal-self and social-self constructs were closely related, The participants rated themselves more like copers than ill, pain-suffering, invalid or hypochondriacal persons. Being a coper, however, was less desirable than being pain free, In essence, these volunteers with low back pain see coping as a necessary evil. This ambivalent and ambiguous construing of coping needs to be further explored in community and patient groups if we are to improve the collaboration between patients and therapists in achieving good pain management.

Validity of self-reported hysterectomy and tubal sterilisation

Both hysterectomy and tubal sterilisation offer significant protection from ovarian cancer, and the risk of cardiovascular disease in women is lowered after hysterectomy. Since little is known about the accuracy of women's self-reports of these procedures, we assessed their reliability and validity using data obtained in a case-control study of ovarian cancer. There was 100 per cent repeatability for both positive and negative histories of hysterectomy and tubal sterilisation among a small sample of women on reinterview. Verification of surgery was sought against surgeons' or medical records, or if these were unavailable, from randomly selected current general practitioners for 51 cases and 155 controls reporting a hysterectomy and 73 cases and 137 controls reporting a tubal sterilisation. Validation rate for self-reported hysterectomy against medical reports (32 cases, 96 controls) was 96 per cent (95 per cent confidence interval (CI) 91 to 99) and for tubal sterilisation (32 cases, 77 controls) it was 88 per cent (CI 81 to 93), which is likely to be an underestimate. Although findings are based on small numbers of women for whom medical reports could be ascertained, they are consistent with other findings that suggest women have good recall of past histories of hysterectomy and tubal sterilisation; this allows long-term effects of these procedures to be studied with reasonable accuracy from self-reports.

Assessment of Occupational Genotoxic Risk among Brazilian Hairdressers

Objectives: To evaluate the genotoxic risk to hairdressers exposed daily to chemical substances such as hair dyes, waving and straightening preparations and manicurists` products by the Comet assay test (single-cell gel electrophoresis). Methods: The Comet assay was performed on blood samples from 69 female hairdressers (36.4 +/- 10.7 years old) currently employed in 21 different beauty institutes in Sao Paulo, Brazil, and on 55 female control blood donors (32.6 +/- 10.0 years old) from the Sao Paulo University Clinical Hospital blood bank. All the control subjects had occupations other than hairdresser. Comet assays were performed by evaluating 100 blood lymphocytes per individual and graded by visual score according to comet tail length. Results: The hairdressers showed a higher frequency of DNA damage revealed by Comet Score (159.8 +/- 71) when compared to the control group (125.4 +/- 64.1), and the difference was statistically significant by the Student`s t-test (P = 0.005). Multiple regression analysis showed that in addition to the hairdressers` profession, tobacco use contributed to the higher frequency of cells with comets (P < 0.05). Conclusions: The observed DNA damage could be associated with the hairdressers` occupational environment, where different chemicals are chronically manipulated and inhaled. Considering that this profession in many countries, including Brazil, is not officially regulated, more attention should focus on these professionals not only by legislative bodies but also by multidisciplinary teams able to develop and implement risk prevention and control strategies for chemical, physical and biological agents to which hairdressers are exposed.

Can Mobile Units Improve the Strategies for Cervical Cancer Prevention?

Cervical cancer is a serious public health problem in women in developing countries because of absence or ineffectiveness of screening programs. Several biases to access medical care and inequity of public health system in a continental country like Brazil limit the implementation of adequate programs to appropriately prevent the cervical cancer. Therefore, the aim of this study was to evaluate the results of applying the mobile unit (MU) for cervical cancer screening. From May 2003 to May 2004, a cervical cancer screening was offered to women aged 20-69 years, residing in 19 municipal districts of the Barretos county region, in Sao Paulo. Out of the 9,560 examination available, 2,964 (31%) women underwent screening. The medium distance traveled by the MU was 45 km. The medium time spent by women in the MU for completion of the questionnaire and doing the exam was 20 minutes. It was observed that 17.0% of women screened had never had the test or had not had it repeated within the last 3 years. The negative response was more common among women aged 20 to 29 years and 60 to 69 years and among women with less schooling and lower socio-economic income (P < 0.05). MU can significantly overcome the chronic deficiency of public health system accessibility offering opportunity to these women to participate in screening programs. Diagn.

Prevalence of Erectile Dysfunction as Defined by the International Index of Erectile Function (IIEF) and Self-Reported Erectile Dysfunction in a Sample of Brazilian Men Who Consider Themselves Healthy

A cross-sectional study was carried out with 288 male blood donors, aged between 40 and 60 years old, with the aim of comparing the prevalence of erectile dysfunction (ED) as defined by the International Index of Erectile Function (IIEF) and that resulting from the simple questioning of the presence of ED. Socio-demographic, clinical, and behavioral factors that are associated with the presence of ED were considered. Erectile dysfunction prevalence in the IIEF was 31.9%, while self-reported ED prevalence was 3.1%. The factors associated to ED, as reported by the IIEF were: professional inactivity, suspected depression and/or anxiety, reduced sexual desired, and self-reported ED.

Validity of the self reporting questionnaire-20 in epidemiological studies with older adults

This study examined the validity of the self-reporting questionnaire (SRQ-20) in a population-based survey with older adults in Sao Paulo, Brazil. The study sample consisted of 2,008 individuals aged 65 years or more who were living in an economically disadvantaged area of the city. The geriatric mental state (GMS) was used as the gold standard for the assessment of common mental disorders (CMD). The optimal SRQ-20 threshold for case definition was 4/5 (sensitivity = 76.1%, specificity = 74.6%, area under ROC curve = 0.82). Women, older participants and those with lower income were more likely to be misclassified by the questionnaire. The inclusion of older persons with dementia or psychosis did not change the ability of the SRQ-20 to identify cases of CMD. The SRQ-20 may be a useful instrument to be used in large epidemiological studies in resource-poor settings for the identification of cases of depression and anxiety in later life. The performance of the SRQ-20 among older adults was similar to that observed with the adult population in Brazil.
