Rural Mexican-American Adolescent Sexual Risk Behavior

CONTEXT: There is a need for community-based, culturally sensitive, cognitive-behavioral interventions to reduce sexual risk behavior among minority adolescents. Studies of adolescent risk and protective behaviors have focused on identifying modifiable psychosocial variables that predict differential outcomes for subsequent intervention efforts. Research has been scarce in studies of rural minority adolescent women. PURPOSE: To examine the protective and risk behaviors of these rural Mexican-American adolescent women and their relationship to physical or sexual abuse. METHODS: Mexican-American adolescent women aged 14-19 years were recruited through a rural health clinic and administered a self-report assessment for protective and risk behavior and sexual, physical, and psychological abuse. FINDINGS: Rural minority adolescent women endured high levels of psychological distress and many risk behaviors yet experienced few protective behaviors. Barriers to health care included access and confidentiality. Physically or sexually abused adolescents endured relatively greater risk and fewer protective behaviors than nonabused. CONCLUSIONS: Rural Mexican-American adolescent women may benefit from confidential identification and assessment of abuse history and risk and protective behaviors so that appropriate psychological treatment can accompany accessible medical treatment. The prevalence of risk behaviors and abuse among these women presents a need for development of behavioral interventions for risk reduction and promotion of health protective behaviors.

Sex role identity and depression in nurses

The relationship between sex role identity and depression in nurses was explored. It was posited that nurses tend to be high in feminine traits and have traditional attitudes and that these traits and attitudes will be correlated with depressive symptoms. The sample consisted of 203 nurses employed at a 350‐bed metropolitan hospital. The research questionnaire included: (a) the Maferr Inventory of Feminine Values, (b) the Bem Sex Role Inventory, (c) the Zung Self‐Rating Depression Scale, and (d) demographic data. It was found that a strong and positive association existed between traditional attitudes toward feminine sex roles and depressive symptoms. However, relationships between feminine traits and depressive symptoms were not found. Data analysis also indicated statistically significant relationships between both androgenous traits, masculine traits, and lack of depressive symptoms. Limitations in scope and sampling procedures were discussed. In addition, the significance to nursing was discussed.     

Social vulnerability and reactions to caregiving in daughters and daughters‐in‐law caring for disabled aging parents

Variables that have been conceptually linked with social vulnerability—income, educational level, employment, cessation of work to provide care, marital status, social support, and health—were used to predict four categories of reaction to caregiving in 159 daughters and daughters‐in‐law caring for their disabled aging parents. Social support, income, and health best predicted negative reactions to caregiving; social support alone best predicted feelings of family abandonment, impact on health, and impact on schedule. Compared with daughters and daughters‐in‐law who had not quit work to provide care, those who had quit work were significantly older, had lower incomes and fewer social supports, and were more involved in care. The results suggest that quitting work may be a precursor to social isolation that places the caregiver at increased risk for social vulnerability and negative reaction to caregiving. The implications of the findings for health care policy are discussed.     

The Role of Serotonin (5-HT) in Behavioral Control: Findings from Animal Research and Clinical Implications

The neurotransmitters serotonin and dopamine both have a critical role in the underlying neurobiology of different behaviors. With focus on the interplay between dopamine and serotonin, it has been proposed that dopamine biases behavior towards habitual responding, and with serotonin offsetting this phenomenon and directing the balance toward more flexible, goal-directed responding. The present focus paper stands in close relationship to the publication by Worbe et al. (2015), which deals with the effects of acute tryptophan depletion, a neurodietary physiological method to decrease central nervous serotonin synthesis in humans for a short period of time, on the balance between hypothetical goal-directed and habitual systems. In that research, acute tryptophan depletion challenge administration and a following short-term reduction in central nervous serotonin synthesis were associated with a shift of behavioral performance towards habitual responding, providing further evidence that central nervous serotonin function modulates the balance between goal-directed and stimulus-response habitual systems of behavioral control. In the present focus paper, we discuss the findings by Worbe and colleagues in light of animal experiments as well as clinical implications and discuss potential future avenues for related research.     

How do people interpret information about colorectal cancer screening: observations from a think‐aloud study

Background

The English NHS Bowel Cancer Screening Programme biennially invites individuals aged 60–74 to participate in screening. The booklet, ‘Bowel Cancer Screening: The Facts'' accompanies this invitation. Its primary aim is to inform potential participants about the aims, advantages and disadvantages of colorectal cancer screening.

Objective

To provide detailed commentary on how individuals process the information contained within ‘The Facts’ booklet.

Design, setting and participants

This study comprised of 18 interviews with individuals aged 45–60 and used a ‘think‐aloud’ paradigm in which participants read aloud the booklet. Participant utterances (verbal statements made in response to researcher‐led prompts) were transcribed and analysed using a combination of content and thematic analysis.

Results

A total of 776 coded utterances were analysed (mean = 43.1 per person; range = 8–95). While overall comprehension was satisfactory, several problem areas were identified such as the use of complex unfamiliar terminology and the presentation of numerical information. Specific sections such as colonoscopy risk information evoked negative emotional responses. Participants made several suggestions for ways in which comprehension might be improved.

Conclusion

Public perceptions of the NHS Bowel Cancer Screening Programme information materials indicated that specific aspects of the booklet were difficult to process. These materials may be an appropriate target to improve public understanding of the aims, benefits and disadvantages of colorectal cancer screening. These findings will contribute to a broader NIHR‐funded project that aims to design a supplementary ‘gist‐based’ information leaflet suitable for low literacy populations.     

A set of double-angled needle holders and long,angled tissue forceps for use in surgery of the abdomen

A set of double-angled needle holders and long, angled tissue forceps have been designed and presented for use in surgery of the abdomen. The problems of passage and control of curved needles in all directions is well recognized. The marriage of design and presentation addresses the mechanical and anatomic needs of surgeons in the pelvis, subdiaphragmatic area, and in large and obese patients. Multiple variables in use provided by these instruments, particularly when used together, enhance surgical control at problem sites.     

Longitudinal associations in adolescence between cortisol and persistent aggressive or rule-breaking behavior

Although several studies have associated antisocial behavior with decreased cortisol awakening responses (CAR), studies in adolescent samples yielded inconsistent results. In adolescence however, the CAR develops and antisocial behavior is heterogeneous in type and persistence. Therefore this longitudinal study compared persistent aggressive and rule-breaking adolescents to low aggressive and rule-breaking adolescents on the development of the CAR from ages 15 to 17 (N = 390). Persistently high aggressive adolescents showed decreased cortisol levels at awakening consistently over the years (Δχ²(1) = 6.655, p = .01) as compared to low aggressive adolescents. No differences between adolescents showing persistent high rule-breaking and low rule-breaking were found. This longitudinal study is the first to show that persistent aggression, but not rule-breaking behavior, is related to neurobiological alterations. Moreover, despite development of the CAR over adolescence, the decrease in cortisol is consistent over time in persistent high aggressive adolescents, which is an important prerequisite for the prediction of persistent aggression.
