Social risk and protective factors for suicide attempts in low income African American men and women

A case-control study was conducted to examine a broad array of potential social risk and protective factors for suicide attempt among 200 African American men and women receiving care at a large, public, urban hospital. Specifically, we examined the effect of the following potential risk factors for suicide attempt: life hassles, partner abuse, partner dissatisfaction, and racist events; as well as the following potential protective factors: effectiveness of obtaining resources, social embeddedness, and social support. Using logistic regression, suicide attempter status was predicted by two independently significant social variables: one risk factor (life hassles) and one protective factor (social support). Male versus female suicide attempters were not distinguished by the social variables. These findings, which support the utility of an ecological conceptualization of risk and protective factors for suicide attempt, help to clarify the independently significant social environment risk and protective factors for suicide attempts among economically disadvantaged African Americans in particular. Research on both risk factors and protective factors provide a basis for culturally competent interventions aimed at reducing both the risk of future suicide attempts and completions.     

Exploring Risk in Early Adolescent African American Youth

Two studies were conducted to explore the degree to which single- and multiple-risk profiles were evident in samples of African American early adolescents in low-income inner-city, rural, and suburban schools. Study 1 examined early adolescent risk status (i.e., single, multiple) in relation to later adjustment in a representative sample (70% European American, 30% African American). Youth who experienced a single risk in early adolescence had moderately increased levels of school dropout and criminal arrests, whereas youth with multiple risks (i.e., combination of 2 or more risks) had significantly increased levels of school dropout, criminal arrests, and teen parenthood. Study 2 examined the extent to which single- and multiple-risk profiles were evident in cross-sectional samples of African American youth from low-income inner-city and rural areas. About one fourth of both the inner-city and rural samples of African American youth were composed of youth in the single-risk category. A significantly greater proportion of boys in the inner-city sample (20%) than boys in the rural sample (13%) experienced multiple risks. Girls across the rural and inner-city samples did not differ in terms of risk. Overall, more than 60% of African American youth in these two low-income samples did not evidence risk for later adjustment problems. Implications for research and intervention are discussed.     

Perceptions of quality of journals related to health education

Faculty and chairpersons (N = 102) at 34 programs granting doctoral degrees in health education were asked to rate the quality of professional journals related to health education. The American Journal of Public Health was the highest rated journal. Health Education Quarterly was second, and Health Education Research, the only other health education journal, was rated in the top 10 (rated 7). The journals from the epidemiology area rated higher than journals from other areas. The respondents were least familiar with journals on the environment, safety, and death education.     

Discovery algorithms for hierarchical relations

Two algorithms based on a latent class model are presented for discovering hierarchical relations that exist among a set ofK dichotomous items. The two algorithms, stepwise forward selection and backward elimination, incorporate statistical criteria for selecting (or deleting) 0–1 response pattern vectors to form the subset of the total possible 2 ^k vectors that uniquely describe the hierarchy. The performances of the algorithms are compared, using computer-constructed data, with those of three competing deterministic approaches based on ordering theory and the calculation of Phi/Phi-max coefficients. The discovery algorithms are also demonstrated on real data sets investigated in the literature.     

Role of Secondary Stressors in the Parental Death–Child Distress Relation

This study examined the psychological consequences and secondary stressors associated with death of a parent. The sample (N = 116) consisted of 26 youths who had lost a parent to homicide, 45 youths who had lost a parent to natural death, and 45 nonbereaved youths. Youngsters completed face-to-face interviews, while their guardians completed measures assessing the children's functioning. Results based on both child and guardian reports indicated that parental death was associated with an increase in secondary stressors, regardless of the mode of death. Findings based on guardian reports also revealed that parental death was related to increased internalizing distress, and that parental death due to homicide was related to increased externalizing distress. Furthermore, secondary stressors mediated the parental death–child distress relation such that parental death led to an increase in stressors, which in turn led to increased child distress. Implications for secondary and tertiary preventive interventions are discussed.     

The functional anatomy of word comprehension and production

This review describes the functional anatomy of word comprehension and production. Data from functional neuroimaging studies of normal subjects are used to determine the distributed set of brain regions that are engaged during particular language tasks and data from studies of patients with neurological damage are used to determine which of these regions are necessary for task performance. This combination of techniques indicates that the left inferior temporal and left posterior inferior parietal cortices are required for accessing semantic knowledge; the left posterior basal temporal lobe and the left frontal operculum are required for translating semantics into phonological output and the left anterior inferior parietal cortex is required for translating orthography to phonology. Further studies are required to establish the specific functions of the different regions and how these functions interact to provide our sophisticated language system.     

A study of area conservation using a simple method of adjustment

The method of adjustment was adapted to study conservation of area with Papua New Guinea High School students. Subjects were shown a standard field, representing “a block of land”, with a “house” in each corner. An identical comparison field. with adjustable borders was presented under one of two conditions. In one condition the houses were placed along one side, and in the other they were placed randomly about the field. Non-conservers were invited to adjust the borders of the comparison field to match the area of the standard. Non-conservers in the Edge condition reduced, and those in the Random condition increased, the size of the comparison field.     

Tonic and phasic orientation in full-term and preterm infants

Thirty-three full-term infants and thirty-eight preterm infants (on average born at 30 weeks gestation) were tested for their latency to turn toward checkered stimulus patterns (phasic orienting or "attention-getting") and for the duration of their initial fixation (tonic orienting or "attention-holding"). Plotted against the logarithm of the subjects' postconceptional age, turning latency fell linearly between 36 and 120 weeks, while fixation time fell abruptly at 53 weeks. Preterm and full-term infants showed the same developmental trends, implying that both of these attentional behaviors are biologically timetabled and that neither is greatly affected by premature extrauterine experience. Unexpectedly, phasic orientation in the first 30 postnatal days was significantly faster in preterm than in full-term infants, and fixation times failed to differ. Despite the necessary functional integration of phasic and tonic orienting in mature visual scanning and attention, the present results suggest an independence in their early postnatal development and that neither is mature at birth.     

Comparison of three antismoking interventions among pregnant women in an urban setting: a randomized trial

This study examined smoking cessation and cigarette reduction of indigent inner city pregnant women (n = 193) who completed one of three interventions: a special video program based on their perceptions of the effects of smoking during pregnancy, the American Lung Association's "Freedom From Smoking For You and Your Baby" program, or the usual physician's advice. Six percent of the women quit smoking, and 43% reduced the number of cigarettes they smoked. There were no significant differences among the three groups for either the number who quit smoking or who reduced the number of cigarettes smoked.
