A systematic meta-review of evaluations of youth violence prevention programs: Common and divergent findings from 25 years of meta-analyses and systematic reviews

Violence among youth is a pervasive public health problem. In order to make progress in reducing the burden of injury and mortality that result from youth violence, it is imperative to identify evidence-based programs and strategies that have a significant impact on violence. There have been many rigorous evaluations of youth violence prevention programs. However, the literature is large, and it is difficult to draw conclusions about what works across evaluations from different disciplines, contexts, and types of programs. The current study reviews the meta-analyses and systematic reviews published prior to 2009 that synthesize evaluations of youth violence prevention programs. This meta-review reports the findings from 37 meta-analyses and 15 systematic reviews; the included reviews were coded on measures of the social ecology, prevention approach, program type, and study design. A majority of the meta-analyses and systematic reviews were found to demonstrate moderate program effects. Meta-analyses yielded marginally smaller effect sizes compared to systematic reviews, and those that included programs targeting family factors showed marginally larger effects than those that did not. In addition, there are a wide range of individual/family, program, and study moderators of program effect sizes. Implications of these findings and suggestions for future research are discussed.     

Social Relationships and Mortality

Social relationships benefit not only mental health but also physical health. This review addresses the following questions: (1) What is the overall magnitude of the effect of social relationships on risk for premature death? (2) How generalized is the effect and are there factors known to influence this association? (3) What are the likely pathways by which social relationships influence longevity? The article concludes by discussing the implications of these findings for potential interventions aimed at reducing risk for mortality.     

On the high intelligence and cognitive achievements of Jews in Britain

A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110–113. New data are presented for two nationally representative samples of 7–16 year olds in which Jews had mean IQs of 108.5 and 107.7. Taking all five studies into account, it is proposed that the best reading of the IQ of Jews in Britain is 110. It is proposed that the best reading of the IQ of Jews in the United States is 109.5. Data are presented for the numbers of Jewish Fellows of the Royal Society in relation to their proportion in the population. It is found that Jews were over-represented by a factor of 3.7 in the years 1901 through 1940 and by a factor of 7.6 in the years 1950 through 2003. Data are also presented for the numbers Jewish Nobel prize-winners in Britain and the United States for 1901 through 2003. It is shown that Jews are over-represented among Nobel prize-winners by a factor of 8.0 in Britain and 12.3 in the United States. It is proposed that the over-representation of Jews among Nobel prize-winners can be partly explained by the higher average Jewish IQ.     

National Differences in Subjective Well-Being: The Interactive Effects of Extraversion and Neuroticism

Extraversion and neuroticism interact to affect subjective well-being (SWB) at the individual level of analysis, so that introverted neurotics tend to be particularly miserable. The goal of this study is to determine if this interaction can also be detected at a national level. Findings based on data from 30 countries confirmed that the interaction between extraversion and neuroticism was an extremely strong predictor of satisfaction with life and affect, and a similar though not significant effect was observed with happiness. Neuroticism lowered satisfaction with life and affect among all nations, but more so among introverted nations than among extraverted ones. These findings further confirm that personality traits can be used to extend our understanding of national differences regarding SWB. They also further validate national SWB scores, as they relate to personality in a complex but theoretically meaningful manner.     

Hyperventilation and anxiety in panic disorder, social phobia, GAD and normal controls

Patients with DSM-III Agoraphobia, Panic Disorder, GAD, Social Phobia and normal controls underwent a series of experimental procedures and measures to determine whether panic attack patients show a greater tendency towards hyperventilation that is independent from their anxiety levels. Contrary to expectations, the Agoraphobia and Panic Disorder patients did not show significantly lower levels of expired pCO2 at rest than the other anxious or non-anxious groups. However, the panic attack patients did show significantly higher levels of anxiety and hyperventilatory symptoms during a hyperventilation test and during breathing 5% CO2 in air. A strong relationship was found between hyperventilatory symptoms and anxiety in all groups of patients and in the controls. On the basis of these results it was concluded that Agoraphobia and Panic Disorder patients do not show a unique tendency toward hyperventilation, but rather that their hyperventilatory symptoms and perhaps intermittent overbreathing episodes are a function of the high levels of anxiety they experience.     

External Variables,Subjective Expected Utility,and Adolescent Behavior with Alcohol and Cigarettes1

A classic social psychological model is that external variables influence behavior through their impact on subjective expected utility, the extent to which more good or harm is expected from behavior. The purpose of this research was to determine whether subjective expected utility is a major intervening variable that links external variables and the onset of alcohol drinking and cigarette smoking. The data are from two longitudinal studies of adolescents. The findings suggest that subjective expected utility does not account for the relationship between external variables and behavior.     

Coping strategies and psychological distress: Prospective analyses of early and middle adolescents

Administered measures of coping, life events, and anxiety and depression to junior high and senior high school samples on two occasions, separated by a 5-month interval. Factor analyses supported the creation of coping subscales for problem solving, cognitive coping, social entertainment, physical exercise, and peer support. A one-item index of parental support was also included in the analyses. The coping subscales showed moderate temporal stability. Mothers' reports of their children's coping provided only marginal support for the validity of the adolescents' self-reports. Prospective regression analyses of the early adolescent data revealed that problem-solving coping was negatively related to depression, and that social entertainment coping was negatively related to anxiety. The prospective effects for the middle adolescents' coping were nonsignificant. The findings are discussed in terms of their implications for the measurement of adolescent coping strategies and research on the relation between these strategies and psychological functioning.     

Subjective Expected Utility,Locus of Control,and Behavior1

Although a fundamental assumption of behavior decision theory is that individuals must generally believe they can control their fate if their behavior is to be influenced by subjective expected utility (SEU), the hypothesis that the positive relationship between SEU and behavior is stronger for those with internal locus of control had not been directly tested. That hypothesis was assessed in two separate longitudinal studies of adolescents. The behavior studied in one sample was the initiation of cigarette smoking, and in the other it was the onset of drinking alcohol. The hypothesis received weak support in both studies.     

Reconstructionist theology in rabbinical counseling

Utilizing the theology of Reconstructionism's founder, Mordecai Kaplan, in rabbinical counseling, the principles and concepts can be seen to be complementary to those of Individual Psychology. It is this similarity and complementary nature that validates this unique theology as a sound and accepted therapeutic tool.     

The community alcohol use scale: A scale for use in prevention programs

The Community Alcohol Use Scale (CAUS) was developed as a continuous, reliable, valid, and acceptable measure for primary prevention studies. Items were written following a comprehensive review of the literature on alcohol dependence and alcoholism. Based upon the responses of 315 respondents to the 100-item initial version of the scale, the 45-item CAUS was developed. The CAUS was then cross-validated on a local sample (n = 274) and a provincial sample (n = 745). Estimates of internal consistency were .91, .96, and .94, respectively, for the initial and cross-validation samples. Correlations of .48 and .69 were obtained between the CAUS and the Michigan Alcohol Screening Test for the initial and local cross-validation samples. In the provincial cross-validation sample a correlation of .62 was obtained between the CAUS and the Usual Weekly Alcohol Index. Preliminary cutting scores were developed to identify those at risk for alcoholism, and alcoholics. The CAUS has potential use as an evaluative and predictive instrument in a variety of primary prevention programs.
