Predictors and outcomes of early motherhood in the Australian Longitudinal Study on Women's Health

Early motherhood is identified as a social problem, and having children at an early age is assumed to lead to psychological distress, welfare dependence and socioeconomic disadvantage. Analysis of responses from 9,689 young participants in the Australian Longitudinal Study on Women's Health was used to examine predictors and outcomes of early motherhood in Australia. Survey 1 (1996, aged 18 - 23) and Survey 2 (2000, aged 22 - 27), were used to categorize women as Childless, Existing Mothers (before Survey 1) and New Mothers (became mothers before Survey 2). Multivariate logistic regressions provided comparisons on sociodemographics, gynaecological variables, psychological wellbeing and health behaviours. Survey 1 data show that Existing Mothers experience socioeconomic disadvantages and unhealthy lifestyles. However, those who will go on to become mothers earlier than their peers already experience similar disadvantages. Further, the Survey 2 data show that, when these pre-existing disadvantages are controlled for, the additional deficits experienced by early mothers are relatively minor. Social disadvantage predisposes women to become mothers early, and to adopt unhealthy behaviours. However, young Australian women cope well with the challenges of early motherhood. In the longer term, unhealthy lifestyles and low education may lead to ill health and disadvantage, but early motherhood is not the initiator of this trajectory.     

An investigation of monitoring for sleep-related threat in primary insomnia

In Study 1, individuals with primary insomnia (n=32) and good sleepers (n=38), recruited from a university population, completed a semi-structured interview. The interview assessed monitoring for sleep-related threat, negative thoughts and safety behaviours, at night and during the day. Compared to good sleepers, individuals with insomnia reported more frequent monitoring at night and during the day, more negative thoughts associated with monitoring at night and during the day, and the use of more safety behaviours associated with monitoring at night. A path analysis showed that the total monitoring frequency was significantly positively related to the score for total negative thoughts, which in turn, was significantly positively related to the total number of safety behaviours used. Study 2 aimed to test the generalisability of these findings in a clinical sample of individuals with primary insomnia (n=23). The results indicated that the clinical sample also engaged in monitoring for sleep-related threat, experienced negative thoughts and used safety behaviours. Further, more severe insomnia was associated with more negative thoughts and the use of more safety behaviours associated with monitoring at night. Together, these results are consistent with the proposal that monitoring for sleep-related threat functions to maintain insomnia by triggering negative thoughts and the use of safety behaviours. Future research is required to verify the proposed causal status of monitoring, using prospective designs and experimental manipulations.     

A Review of Spiritual and Religious Measures in Nursing Research Journals: 1995--1999

Background: A series of systematic reviews has revealed relatively high levels of interest in religion and spirituality in different nursing specialties, but not in general nursing research journals. Purpose: To identify the extent to which spirituality and religiousness were measured in all quantitative and qualitative research articles published in Research in Nursing and Health, Nursing Research, Advances in Nursing Science (ANS), and Image: The Journal of Nursing Scholarship from 1995 to 1999. Methods: A full-text search was conducted of ANS and Image using the Ovid search system. Nursing Research and Research in Nursing and Health were hand searched for spiritual/religious measures. Characteristics of selected studies, the measures taken, and their uses were coded for data analysis. Results: A total of 564 research studies were identified, of which 67 (11.9%) included at least one measure of spirituality or religiousness. A significant difference was found between the percentage of qualitative and quantitative studies that contained measures of these concepts. Of the 119 qualitative studies, 23 (19.3%) contained a measure of religion or spirituality, compared to 44 of the 445 (9.9%) quantitative studies. Nominal indicators of religious affiliation were the most commonly used measures in the quantitative studies and measures of religion and spirituality were rarely used in the analyses. Although only a few quantitative or qualitative studies intended to focus on religion or spirituality, these themes often emerged spontaneously in the qualitative research. Conclusions: Research in Nursing and Health, Advances in Nursing Science, Nursing Research, and Image: The Journal of Nursing Scholarship all published research measuring spirituality and religiousness during the time-period studied. The rate at which spirituality and religion appeared in these nursing research articles is substantially higher than that found in most fields outside of nursing. Even more frequent inclusion of spiritual and religious variables and richer measures of spirituality and religiousness would help to increase the available scientific information on the role of spirituality and religion in nursing care.     

Are Successful Applicants to the Priesthood Psychologically Healthy?

The current investigation evaluated psychological and personality profiles of successful applicants to a major Roman Catholic religious order. The MMPI-2 and 16PF were administered to 68 applicants between 1990 and 2004 who subsequently entered seminary. Results indicate that these applicants to the priesthood were generally well-adjusted as well as being socially responsible, interpersonally sensitive and sociable. Findings also suggest some tendency for defensiveness and repression. Furthermore, dealing with perceived negative impulses such as anger and hostility may also be a concern for many of these men.     

A methodology for assessing the functions of emerging speech in children with developmental disabilities

An approach based on Skinner's (1957) theory of verbal behavior has been developed to understand and teach elementary communication skills to children with autism and developmental disabilities (Sundberg & Partington, 1998). However, few studies have directly examined the characteristics of emerging language in children with developmental disabilities. The purpose of this study was to develop and evaluate an assessment for identifying the elementary functions of vocal speech in children. Participants were 4 children with developmental disabilities, aged 6 years to 12 years, who exhibited at least one distinguishable vocal response (word or phrase) frequently in the natural environment. The assessment focused on three verbal operants delineated by Skinner (mand, tact, and intraverbal). One or more functions were identified for at least one vocal response of each child. Results suggested that this assessment would be useful for (a) evaluating Skinner's theory, (b) guiding decisions about language training for individual children, and (c) studying the nature of expressive language development in children with developmental disabilities.     

"I'm OK but you're not" and other peer-relational schemas: explaining individual differences in children's social goals

This study examined the links among 5th and 6th graders' (279 girls and 310 boys) self- and peer perceptions, social goals, and social behavior. Social goals mediated the effects of self- and peer perceptions on 3 types of behavior: proactive aggression, prosocial behavior, and withdrawal. In addition to their main effects (self-perception predicting variance in agentic goals, peer perception being related to communal goals), self- and peer perception interacted in influencing social goals; for instance, the effects of a positive view of oneself were different in the contexts of a positive versus a negative perception of peers. It is suggested that in order to predict children's social behavior more accurately, researchers should investigate children's dual perceptions of themselves and of their peers--that is, their peer-relational schemas--instead of assessing self-perception and peer perception in isolation from each other.     

Misperception of sleep can adversely affect daytime functioning in insomnia

This experiment was designed to investigate the relationship between subjective perception of sleep and daytime processes in primary insomnia. Twenty-two individuals with primary insomnia received positive or negative feedback about their sleep, immediately on waking, on three consecutive mornings. The positive feedback was that last night's sleep was good quality. The negative feedback was that last night's sleep was poor quality. Objective sleep on each of the three nights was estimated by actigraphy and did not differ across the three nights or the two feedback conditions. Negative feedback (based on 32 nights of data) was associated with more negative thoughts, sleepiness, monitoring for sleep-related threat, and safety behaviours during the day, relative to positive feedback (based on 34 nights of data). These results indicate that the impaired daytime functioning reported by insomnia patients is maintained, at least in part, by subjective perception of sleep.     

Adult age and digit symbol substitution performance: a meta-analysis

This article reports the results of a meta-analysis of the effects of age, education, and estimated year of measurement on scores from the Wechsler Adult Intelligence Scale and the Wechsler Adult Intelligence Scale-Revised Digit Symbol Substitution Test. Analysis of effect sizes for age reported in 141 studies published between 1986 and 2002 indicated a mean standardized difference of -2.07. Age accounted for 86% of the variance in a regression model using age, education, and year submitted as predictors of Digit Symbol scores. There was no association between years of education or year submitted and Digit Symbol scores for younger adults or older adults.     

Substance use, suicidal ideation and attempts in children and adolescents

Using data from a community sample of youth ( N = 1,458; ages 9-17), this study assessed the association between adolescent substance use/abuse and suicidal behaviors. Suicide attempts were strongly associated with alcohol abuse and dependence, followed by frequent cigarette smoking. The associations remained significant even after controlling for depression. The associations between substance use/abuse and suicidal ideation were no longer significant after controlling for depression. These findings highlight the important role that substance use plays in adolescent suicidal behaviors.     

Age and responding-hand related changes in performance of neurologically normal subjects on the line-bisection and chimeric-faces tasks

This study investigated age and responding-hand (left, right, and bimanual) related changes in visuospatial attention. Two tasks were completed by 107 neurologically normal right-handed subjects ranging in age from 5 to 70 years and distributed across four age groups. Task-specific differences between groups were apparent. In the line-bisection task, the younger and older groups displayed symmetrical neglect while the young and middle groups displayed pseudoneglect. In the chimeric-faces task the leftward bias was less pronounced in the older group and more susceptible to responding-hand effects in the middle and older groups. Whilst results, especially those of the bimanual method, provided strong support for an activation model, they imposed an age limitation on its appropriateness as an explanation for performance on the chimeric-faces task. Results are discussed as reflecting changes in the corpus callosum and right hemisphere.
