RESUMEN

Scholars have warned that mental health anti-stigma campaigns targeting the general public can possibly be detrimental to some who are stigmatized. Scholars also have noted that people with depression respond to some public service announcements (PSAs) differently than those without. Accordingly, the current study explored whether anti-stigma PSAs targeting the general public could cause problematic outcomes for people with depression. Participants with (n = 55) and without (n = 133) heightened depressive symptomatology viewed two mental health anti-stigma PSAs. Participants provided thoughts about the PSAs through a single, open-ended question. To allow for an assessment of convergence, participants rated overall favorability toward each PSA through a close-ended item. Results indicated that most qualitative responses were favorable; however, 23.6% of respondents with heightened depressive symptomatology, compared to 1.5% without, provided responses coded as indicating that at least one PSA caused unintended negative affect, χ2(1) = 25.96, [Formula: see text] p < .001. Evidence of untoward effects primarily came from the Friend PSA and the qualitative responses indicate how this occurred. Moreover, complementing the qualitative coding, the Friend PSA was rated less favorably by participants with heightened depressive symptomatology (M = 5.00, SD = 1.67), than those without (M = 5.64, SD = 1.44), F(1, 186) = 6.99, p = .009, ηp2 = .036. There were no significant differences in quantitative favorability ratings regarding the Labeling PSA. Indicating that further investigation is warranted, results suggest it is possible for an anti-stigma PSA targeting the general public to cause unintended negative affect among some people with depression.

RESUMEN

Little research is available on the role of religious coping among youth exposed to disasters. This study examined the role of general and religious coping in a sample of 669 Sri Lankan Buddhist, Hindu, Muslim, and Christian youth (mean age = 14). Youth completed a survey with measures of exposure to disaster-related stressors, psychological and psychosocial functioning, and general and religious coping. Exposure to stressors was the most consistent predictor of negative outcomes, while approach-related coping predicted better outcomes for Buddhist and Hindu youth. Religious coping was the highest reported type of coping for all four religious groups, but was not significantly associated with any of the measured outcomes. The results suggest that Sri Lankan youth of different religious backgrounds are probably more similar than different in the ways they cope with adversity.

RESUMEN

BACKGROUND AND OBJECTIVE: Social support is known to be an important protective factor against elder financial exploitation (FE), yet few empirical studies have examined the relationship between FE and distinct components of social support. Perceived social support, social network size, and interactions with close network members (positive and negative) were measured separately and tested as potential predictors of FE. RESEARCH DESIGN AND METHODS: Three hundred and ninety-five community-dwelling adults aged 60 and older were recruited to complete a 90-minute survey and interview. We used OLS regression to examine the role of social support in FE. Other risk factors associated with FE including dependency, poor physical health, depression, cognition, and demographic characteristics were included as potential predictors. RESULTS: Negative interactions with close network members predicted FE, and remained predictive when all other variables and social support factors were included in the model. Other social support factors were not unique predictors of FE. DISCUSSION AND IMPLICATIONS: Negative social interactions with close network members are important to assess and consider in FE prevention and intervention programs; relationships between social interactions and other risk factors warrant further attention.

RESUMEN

Older adults experience declines in deliberative decisional capacities, while their affective or experiential abilities tend to remain intact (Peters & Bruine de Bruin, 2012). The current study used this framework to investigate age differences in description-based and experience-based decision-making tasks. Description-based tasks emphasize deliberative processing by allowing decision makers to analyze explicit descriptions of choice-reward information. Experience-based tasks emphasize affective or experiential processing because they lack the explicit choice-reward information, forcing decision makers to rely on feelings and information derived from past experiences. This study used the Columbia Card Task (CCT) as a description-based task where probability information is provided and the Iowa Gambling Task (IGT) as an experience-based task, where it is not. As predicted, compared to younger adults (N = 65), older adults (N = 65) performed more poorly on the CCT but performed similarly on the IGT. Deliberative capacities (i.e., executive control and numeracy abilities) explained the relationship between age and performance on the CCT, suggesting that age-related differences in description-based decision-making tasks are related to declines in deliberative capacities. However, deliberative capacities were not associated with performance on the IGT for either older or younger adults. Nevertheless, on the IGT, older adults reported more use of affect-based strategies versus deliberative strategies, whereas younger adults reported similar use of these strategies. This finding offers partial support for the idea that decision-making tasks that rely on deliberate processing are more likely to demonstrate age effects than those that are more experiential.

RESUMEN

Alcohol myopia theory conceptualizes the ability of alcohol to narrow attention and how this demand on mental resources produces the impairments of self-inflation, relief, and excess. The current research was designed to develop and validate a scale based on this framework. People who were alcohol users rated items representing myopic experiences arising from drinking episodes in the past month. In Study 1 (N = 260), the preliminary 3-factor structure was supported by exploratory factor analysis. In Study 2 (N = 289), the 3-factor structure was substantiated with confirmatory factor analysis, and it was superior in fit to an empirically indefensible 1-factor structure. The final 14-item scale was evaluated with internal consistency reliability, discriminant validity, convergent validity, criterion validity, and incremental validity. The alcohol myopia scale (AMS) illuminates conceptual underpinnings of this theory and yields insights for understanding the tunnel vision that arises from intoxication.

RESUMEN

Variables from the Health Tracking Household Survey 2007 were mapped to fit the "integrative model" of patient-doctor communication proposed by Ashton et al. (2003) to describe how communication patterns between patients and doctors influence patients' health outcomes. Patients' perceptions of their physician's attentiveness were examined to determine if perceived attentiveness mediated the relationship between physicians' recommendations (to diet and exercise) and health. Ethnic group differences related to these variables were explored. Overall, patient perception of physician attentiveness did significantly mediate the relationship between recommendations and patients' general health status. Hispanics and African Americans perceived their physicians as significantly less attentive to them, compared to Caucasians' perception of attentiveness. Across all ethnic groups, there was no evidence that doctors' recommendations to diet and exercise had an effect on patients' body mass index. The findings support previous research regarding the importance of physicians' communication skills and cultural sensitivity in promoting patient adherence to health recommendations.

RESUMEN

Research indicates that peer and maternal bonds play important but sometimes contrasting roles in the outcomes of children. Less is known about attachment bonds to these 2 reference groups in young adults. Using a sample of 351 participants (18 to 20 years of age), the research integrated two theoretical traditions: attachment theory and theory of planned behavior (TPB). The predictive contribution of both theories was examined in the context of underage adult alcohol use. Using full structural equation modeling, results substantiated the hypotheses that secure peer attachment positively predicted norms and behavioral control toward alcohol, but secure maternal attachment inversely predicted attitudes and behavioral control toward alcohol. Alcohol attitudes, norms, and behavioral control each uniquely explained alcohol intentions, which anticipated an increase in alcohol behavior 1 month later. The hypothesized processes were statistically corroborated by tests of indirect and total effects. These findings support recommendations for programs designed to curtail risky levels of underage drinking using the tenets of attachment theory and TPB.

RESUMEN

Daily stressors may mediate the relation between exposure to disaster-related stressors and psychological and psychosocial distress among youth in disaster-affected countries. A sample of 427 Sri Lankan Sinhalese, Tamil, and Muslim youth (mean age = 14.5) completed a survey with measures of exposure to disaster-related stressors and daily stressors, psychological distress (posttraumatic stress, depression, and anxiety), and psychosocial distress. The results indicated that daily stressors significantly mediated relations between war- and tsunami-related stressors and psychological and psychosocial distress. Some daily stressors not directly related to disaster also predicted functioning. These results point to the need for policies and interventions that focus on reducing proximal daily stressors that are salient to Sri Lankan youth exposed to disasters.

RESUMEN

This research investigated demographic and attitudinal- psychological predictors of verdict and amount of punitive damages awarded in high-stakes civil litigation. Four hundred and forty-six surrogate jurors, selected to be representative of actual jurors, were exposed to realistic case presentations in insurance, tobacco, and pharmaceutical cases that were about to go to trial. Hierarchical regression revealed that perceptions of the existence of a litigation crisis predicted verdict in the tobacco and pharmaceutical cases after controlling for all other variables. Demographic variables predicted verdict and punitive damage awards only modestly and in different ways in the three cases. Need for cognition, strength of will and rationality, and a perception that there is a litigation crisis predicted the amount of punitive damages awarded in the tobacco case. Litigation crisis also predicted the amount of punitive damages awarded in the pharmaceutical case. Implications for jury selection are discussed.

RESUMEN

Determinants of driving under the influence of alcohol (DUI) were explored among a sample of relatively young Mexican-American males with limited income and education, high levels of alcohol consumption, and regular vehicle use. Data were collected using questionnaires (N=104) and focus groups (N=27), including a focus group with wives and girlfriends (N=4). Four mechanisms that may contribute to the high rate of DUI behavior in this population were identified: (1) a subculture of permissiveness toward drinking and driving for men, (2) heavy drinking, promoted by machismo and a propensity to measure masculinity with alcohol intake, (3) inadequate knowledge of DUI statutes and inadequate understanding of the relationships between BAC, impairment, and crash risk, and (4) for undocumented drivers, lack of accountability in case of an alcohol-related incident.

RESUMEN

The purpose of the present study was to investigate basic methodological issues related to the usage of an examination stress protocol in studies of psychoneuroendocrinology. In the present study, 57 undergraduate students served as participants. All subjects provided salivary samples and completed psychological inventories during a low examination stress period and again during a high examination stress period. Salivary samples were analyzed for cortisol. Three major findings were observed. First, the examination stress protocol proved to be an effective trigger of elevations in both psychological measures of stress and in cortisol levels. Second, sex differences were observed in cortisol levels, such that males showed an elevation in cortisol during the high examination stress session whereas females did not. Finally, no significant correlations were observed between elevations in psychological measures of stress and elevations in cortisol levels. These findings suggest that the examination stress protocol used in the present study effectively elevated both psychological stress and cortisol levels. Furthermore, these findings suggest that there are biological differences in how males and females respond to stress. Finally, no evidence was found to suggest a relationship between psychological and hormonal levels of stress. Together, these findings suggest the need to better define and consider the implications of both the specific measures of stress being used and individual differences in the subject samples in psychoendocrine studies.

RESUMEN

BACKGROUND: Despite numerous published reports, there is no consensus in the literature as to whether the surgical repair of the pectus excavatum improves cardiovascular function. As a result, it has been suggested that correction should be considered a cosmetic procedure, and therefore, many health insurance companies have questioned whether the repair of the pectus excavatum improves cardiovascular function and thus are reluctant to authorize the procedure. The purpose of this study was to apply metaanalysis methodology to generate a quantitative synthesis of the effects of surgical repair on cardiovascular function and to test the hypothesis that surgical repair of the pectus excavatum results in significant improvements in cardiovascular function. METHODS: Studies were retrieved via computerized literature searches, cross-referencing from original and review articles, and a review of the reference list by a recognized authority in the area of pectus excavatum repair. The inclusion criteria were as follows: (1) reporting quantitative measures of preoperative and postoperative cardiovascular function; (2) published in the English language; (3) indexed between January 1960 and May 2005; (4) reporting the duration between which preoperative and postoperative assessments were conducted; and (5) describing the cardiovascular assessment procedures. RESULTS: A comprehensive search of the literature identified eight studies that met all of the inclusion criteria. These studies, representing 169 pectus excavatum patients, were used for the metaanalysis. Random-effects modeling yielded a mean weighted effect size (ES) for cardiovascular function that was statistically significant (ES, 0.59; 95% confidence interval, 0.25 to 0.92; p = 0.0006). CONCLUSIONS: The findings of the present study indicated that surgical repair of the pectus excavatum significantly improves cardiovascular function and contradicts arguments that surgical repair is primarily cosmetic yielding minimal physiologic improvement.

RESUMEN

The purpose of this study was to use a meta-analytical technique to examine the efficacy of surgical repair of pectus excavatum on pulmonary function. Studies were retrieved via computerized literature searches, cross-referencing from original and review articles. Inclusion criteria were as follows: (1) reporting quantitative measures of preoperative and postoperative pulmonary function; (2) published in the English language; (3) indexed between January 1960 and September 2005; (4) reporting the duration between which preoperative and postoperative assessments were conducted; and (5) describing the pulmonary assessment procedures. The titles and abstracts of potentially relevant articles were reviewed to determine whether they met the criteria for inclusion. Twelve studies representing 313 pectus excavatum patients met the inclusion criteria and were used for the meta-analysis. Random-effects modeling yielded a mean weighted effect size (ES) for pulmonary function which was statistically nonsignificant (ES=0.08, 95% CI=-0.20 to 0.35; P=0.58). The findings of the present study indicated that surgical repair of pectus excavatum does not significantly improve pulmonary function. These findings, however, may be a result of testing pulmonary function under conditions in which pectus excavatum does not manifest itself.

RESUMEN

The purposes of the present study were to (a) modify previously published Vo(2)max equations using the constant error (CE = mean difference between actual and predicted Vo(2)max) values from Malek et al. (28); (b) cross-validate the modified equations to determine their accuracy for estimating Vo(2)max in aerobically trained men; (c) derive a new non- exercise-based equation for estimating Vo(2)max in aerobically trained men if the modified equations are not found to be accurate; and (d) cross-validate the new Vo(2)max equation using the predicted residual sum of squares (PRESS) statistic and an independent sample of aerobically trained men. One hundred and fifty-two aerobically trained men (Vo(2)max mean +/- SD = 4,154 +/- 629 ml.min(-1)) performed a maximal incremental test on a cycle ergometer to determine actual Vo(2)max. An aerobically trained man was defined as someone who had participated in continuous aerobic exercise 3 or more sessions per week for a minimum of 1 hour per session for at least the past 18 months. Nine previously published Vo(2)max equations were modified for use with aerobically trained men. The predicted Vo(2)max values from the 9 modified equations were compared to actual Vo(2)max by examining the CE, standard error of estimate (SEE), validity coefficient (r), and total error (TE). Cross-validation of the modified non-exercise-based equations on a random subsample of 50 subjects resulted in a %TE > or = 13% of the mean of actual Vo(2)max. Therefore, the following non-exercise-based Vo(2)max equation was derived from a random subsample of 112 subjects: Vo(2)max (ml.min(-1)) = 27.387(weight in kg) + 26.634(height in cm) - 27.572(age in years) + 26.161(h.wk(-1) of training) + 114.904(intensity of training using the Borg 6-20 scale) + 506.752(natural log of years of training) - 4,609.791 (R = 0.82, R(2) adjusted = 0.65, and SEE = 378 ml.min(-1)). Cross-validation of this equation on the remaining sample of 40 subjects resulted in a %TE of 10%. Therefore, the non-exercise-based equation derived in the present study is recommended for estimating Vo(2)max in aerobically trained men.

RESUMEN

PURPOSE: The purposes of the present study were to (a) modify previously published VO2(max) equations using the constant error (CE) values for aerobically trained females, (b) cross-validate the modified equations to determine their accuracy for estimating VO2(max) in aerobically trained females, (c) derive a new nonexercise-based equation for estimating VO2(max) in aerobically trained females if the modified equations are found to be inaccurate, and (d) cross-validate the new VO2(max) equation using the PRESS statistic and an independent sample of aerobically trained females. METHODS: A total of 115 aerobically trained females (mean +/- SD: age = 38.5 +/- 9.4 yr) performed a maximal incremental test on a cycle ergometer to determine actual VO2(max). The predicted VO2(max) values from nine published equations were compared with actual VO2(max) by examining the CE, standard error of estimate (SEE), validity coefficient (r), and total error (TE). RESULTS: Cross-validation of the modified nonexercise-based equations on a random subsample of 50 subjects resulted in a %TE > or = 13% of the mean of actual VO2(max). Therefore, the following nonexercise-based VO2(max) equation was derived on a random subsample of 80 subjects: VO2(max) (mL x min(-1)) = 18.528 (weight in kg) + 11.993 (height in cm) - 17.197(age in yr) + 23.522 (h x wk(-1) of training) + 62.118 (intensity of training using the Borg 6-20) + 278.262 (natural log of years of training) - 1375.878 (R = 0.83, R2 adjusted = 0.67, and SEE = 259 mL x min(-1)). Cross-validation of this equation on the remaining sample of 35 subjects resulted in a %TE of 10%. CONCLUSIONS: The nonexercise equation presented here is recommended over previously published equations for estimating VO2(max) in aerobically trained females.

RESUMEN

PURPOSE: The purpose of this investigation was to cross-validate existing VO2max prediction equations on samples of aerobically trained males and females. METHODS: A total of 142 aerobically trained males (mean +/- SD; 39.0 +/- 11.1 yr, N = 93) and females (39.7 +/- 10.1 yr, N = 49) performed a maximal incremental test to determine actual VO2max on a cycle ergometer. The predicted VO2max values from 18 equations (nine for each gender) were compared with actual VO2max by examining the constant error (CE), standard error of estimate (SEE), correlation coefficient (r), and total error (TE). RESULTS: The results of this investigation indicated that all of the equations resulted in significant (P < 0.006) CE values ranging from -216 to 1415 mL x min(-1) for the males and 132 to 1037 mL x min(-1) for the females. In addition the SEE, r, and TE values ranged from 266 to 609 mL x min(-1), 0.36 to 0.88, and 317 to 1535 mL x min(-1), respectively. Furthermore, the lowest TE values for the males and females represented 10% and 12% of the mean actual VO2max values, respectively. CONCLUSIONS: The results of the analysis indicated that the two equations using age, body weight, and the power output achieved at VO2 as predictor variables had the lowest SEE (7.7-9.8% of actual VO2max) and TE (10-12% of actual VO2max) values and are recommended for estimating VO2max in aerobically trained males and females. The magnitude of the TE values (>or= 20% of actual VO2max) associated with the remaining 16 equations, however, were too large to be of practical value for estimating VO2max.

RESUMEN

Using a questionnaire developed for the current study, the Fitness Instructors Knowledge Assessment (FIKA(Copyright )), we examined relations between commonly used indicators of knowledge (training and experience) and actual knowledge in the five areas of (a) nutrition, (b) health screening, (c) testing protocols, (d) exercise prescription, and (e) general training knowledge regarding special populations. FIKA provided reliable measures of knowledge in these areas, which are of critical importance in developing an optimal fitness program for the client and for avoiding unnecessary injuries. A survey of 115 health fitness professionals revealed that a bachelor's degree in the field of exercise science and possession of American College of Sports Medicine or the National Strength and Conditioning Association certifications as opposed to other certifications were strong predictors of a personal trainer's knowledge, whereas years of experience was not related to knowledge. These findings suggest that personal fitness trainers should have licensing requirements, such as a bachelor's degree in exercise science and certification by an organization whose criteria are extensive and widely accepted, before being allowed to practice their craft.
