Work and nonwork stressors,negative affective states,and pain complaints among firefighters and paramedics

Prior research has suggested that occupational stressors may contribute to the etiology, progression, and chronicity of pain problems in workers. This study used anonymous survey methods to assess the prevalence and frequency of self-reported pain symptoms and their relationships to demographic variables, sources of occupational stressors, nonwork stressors and affective distress in a large sample (N2000) of employed career public sector firefighters and paramedics. The findings were consistent with those of previous studies of high strain workers. More than 95% of the firefighter/paramedic sample reported at least one pain complaint (using a 1 week assessment time frame). A hierarchical multiple regression analysis entering demographic, occupational, and nonwork stressors, as well as measures of negative affective states targeting total pain scores, yielded significant relationships. Five occupational stressors were associated with respondent pain complaints. The results also suggest that negative affective states mediated the relationships between work and nonwork variables, and pain complaint outcomes. The implications of these findings for the development of preventive interventions for firefighters and paramedics as well as other emergency service workers are considered.     

Acoustic Distinctions in the Speech of Male Psychopaths

A key feature of psychopathy is the ability to deceive, manipulate, and con the unwary, while seeming to be perfectly sincere. Is this impression of sincerity achieved solely through body gestures and facial expression, or is there also something different about the voice quality of psychopaths? We analyzed the acoustic characteristics of speech in 20 male offenders (10 psychopaths and 10 nonpsychopaths), assessed with the Psychopathy Checklist—Revised (Hare, 1991). We used a computer program developed by Alpert, Merewether, Homel, Martz, and Lomask (1986) to measure variations in amplitude and prosody. Results indicated that psychopaths spoke more quietly than controls and did not differentiate, in voice emphasis, between neutral and affective words. These findings are consistent with the developing view that psychopaths are insensitive to the emotional connotations of language. In addition, their vocal characteristics may be part of a self-presentation mode designed to manipulate and control interpersonal interactions.     

The effects of television on children's stereotyping of women's work roles

Sixty-seven elementary school students, ages 5 through 10 years, from three ethnic groups were systematically exposed, over a 1-month period, to specially produced television commercials. One treatment group viewed prevideotaped cartoons interspersed with commercials of women in “traditional” roles, while a second group viewed the same cartoons but with commercials which portrayed women in traditionally male or “reversed” roles. Children were measured on pre-and post-tests on (1) their occupational knowledge, (2) the extent to which they stereotyped occupations, and (3) their own preferences for traditionally male and female jobs. Results indicate that children do learn about occupations from television content, that they also learn to stereotype or nonstereotype various occupations based on the sex of the TV model, and, finally, that girls will change their preferences for various occupations based on the particular roles they view women portrayed in.     

Residual effects of lead poisoning on denver Developmental Screening Test scores

Subtest and Total scores on the Denver Developmental Screening Test were examined for a group of 22 preschool- aged low-income children who had been lead-poisoned, then medically deleaded. Pretest scores were obtained before blood lead elevations occurred;posttest scores were obtained an average of 4.5 months after deleading. Pretest scores were comparable to those of a matched Control group, but posttest scores on the Fine Motor-Adaptive subtest declined, indicating significant residual effects of lead poisoning.The authors wish to acknowledge the support of Shirley Nelson of the Tulane University School of Social Work, and Catherine Kitchens and Percy Rosenbaum of the Lead Poisoning Prevention Program of the New Orleans Health Department.     

Interrelationships among dependency,empathy, and sharing

The sharing behavior of 66 fourth-grade students was observed in two different experimental situations: (a) in the experimenter's presence (visible sharing), and (b) anonymously (invisible sharing). In addition, measures of empathy and dependency were given to each child. For girls some support was found for a positive relationship between empathy and sharing in both of the experimental conditions; also, moderate dependency, as measured by peer and teacher ratings, was related to invisible sharing. The correlations found among the variables were quite different for boys. Both empathy and dependency, as measured by the Children's Social Desirability Questionnaire, were negatively related to invisible sharing, and empathy was positively correlated to social desirability scores. Also, as indicated by curvilinear analyses, the interrelationships among these variables for boys were more complex than were suggested by simple linear correlations.     

Caregiver Attitudes About Patients Told They Have Alzheimer's Disease After Truth Disclosure

We wished to determine caregiver attitudes about telling patients they have Alzheimer's disease (AD). At a clinic visit, the patient, caregiver, and other family members were informed of the diagnosis of AD in a frank discussion. Caregivers accompanying patients to the Memory Disorders Clinic (MDC) were interviewed in a postvisit telephone survey 3–12 months after the truth disclosure visit. Of the 37 caregivers of a consecutive series of AD clinic patients we contacted, 35 agreed to the interview. Of those caregivers interviewed, 68.6% agreed that it had been a good idea to tell the patient the diagnosis, although 11.4% disagreed. 74.3% thought that the truth disclosure had not been too upsetting; 20% disagreed. Caregivers with more education were more likely to agree that patients should be informed. Neither the relationship of the caregiver to the patient, the patient's age, sex, education level, nor degree of dementia were predictive of the caregiver's attitude about informing the patient. Most Caregivers agreed with disclosing the diagnosis. Only a small group of patients were judged very upset after hearing the diagnosis. Even for those patients, caregivers generally felt that an honest discussion of the diagnosis had been helpful.     

Prediction of outcome from cognitive-behavioral treatment of irritable bowel syndrome

The presence of a diagnosable Axis I psychiatric disorder predicted significantly (P < 0.001) lower likelihood of significant improvement among 90 irritable bowel syndrome patients given cognitive and behavioral treatments to help the disorder. Other psychological tests, including the MMPI, BDI, STAI, as well as demographic variables, failed to yield significant prediction.     

Genetic causal beliefs about obesity,self-efficacy for weight control,and obesity-related behaviours in a middle-aged female cohort

Objective: Obesity is a heritable condition with well-established risk-reducing behaviours. Studies have shown that beliefs about the causes of obesity are associated with diet and exercise behaviour. Identifying mechanisms linking causal beliefs and behaviours is important for obesity prevention and control.

Design: Cross-sectional multi-level regression analyses of self-efficacy for weight control as a possible mediator of obesity attributions (diet, physical activity, genetic) and preventive behaviours in 487 non-Hispanic White women from South King County, Washington.

Main Outcome Measures: Self-reported daily fruit and vegetable intake and weekly leisure-time physical activity.

Results: Diet causal beliefs were positively associated with fruit and vegetable intake, with self-efficacy for weight control partially accounting for this association. Self-efficacy for weight control also indirectly linked physical activity attributions and physical activity behaviour. Relationships between genetic causal beliefs, self-efficacy for weight control, and obesity-related behaviours differed by obesity status. Self-efficacy for weight control contributed to negative associations between genetic causal attributions and obesity-related behaviours in non-obese, but not obese, women.

Conclusion: Self-efficacy is an important construct to include in studies of genetic causal beliefs and behavioural self-regulation. Theoretical and longitudinal work is needed to clarify the causal nature of these relationships and other mediating and moderating factors.     

Learning from Instructor‐managed and Self‐managed Split‐attention Materials

Instructor‐managed physical integration of mutually dependent, but spatially separated materials, is an effective way to overcome negative effects of split‐attention on learning. This study examined whether teaching students to self‐manage split‐attention materials would be effective for learning. Seventy‐eight primary‐school students learned about the water cycle, either by studying split‐attention examples, integrated examples or self‐managed split‐attention examples. It was hypothesised that students who study instructor‐integrated materials and students who study self‐integrated materials would outperform students who study split‐attention materials. The results showed that students learned more from instructor‐integrated materials than from split‐attention materials, thereby confirming the split‐attention effect. The implications for future research on self‐management are discussed.Copyright © 2015 John Wiley & Sons, Ltd.
