External Validity and Evaluation Research: A Codification of Problems

This paper delimits and explicates threats to external validity particularly problematic in evaluation research. Five categories of factors are discussed: selection effects, measurement effects, confounded treatment effects, situational effects, and effects due to differential mortality. The paper focuses on pointing up specific ways in which each of the factors threaten generalizability and possible solutions to the methodological problems presented

Housewives\u27 Self-Esteem and their Husbands\u27 Success: The Myth of Vicarious Involvement

This study tests the common assertion that women, especially upper middle-class housewives, vicariously experience their husbands’ success. Our findings for 121 mostly upper middle-class housewives disprove this assertion. Husbands’ success does positively affect a housewife’s self-esteem, but only indirectly, through its effect on perceived marital success. Only husband’s income has a direct positive effect on self-esteem, while other successes of the husband actually lower her self-esteem. These findings, made more dramatic by a comparison with professional married women for whom none of the above effects appear, demonstrate the ambiguous impact traditional marriage has on women. Since marriage is traditionally a basis for a woman’s identity, successful marriage increases her feelings of worth. However, the specific role arrangement may reduce her feelings of personal competence

Factor Structure and Validity of the Body Parts Satisfaction Scale: Results from the 1972 Psychology Today Survey

In 1972, the first major national study on body image was conducted under the auspices of Psychology Today. Body image was assessed with the Body Parts Satisfaction Scale, which examined the dissatisfaction people experienced with 24 aspects of their bodies. Despite the continued reliance on this scale and reference to the study, data on the factor structure of this measure in a sample of adults have never been published, and citations of the original scale have relied on an unpublished manuscript (Bohrnstedt, 1977). An exploratory factor analysis conducted on 2,013 adults revealed factors for men (Face, Sex Organ, Height, Lower Body, Mid Torso, Upper Torso, Height) and women (Face, Sex Organ, Height, Lower Torso, Mid Torso, Extremities, Breast). The factors were weakly to moderately intercorrelated, suggesting the scale can be analyzed by items, by subscales, or by total score. People who reported more dissatisfaction with their body also tended to report lower self-esteem and less comfort interacting with members of the other sex. The analyses provide a useful comparison point for researchers looking to examine gender differences in dissatisfaction with specific aspects of the body, as well as the factor structures linking these items

Susceptibility to Peer Pressure, Self-Esteem, and Health Locus of Control as Correlates of Adolescent Substance Abuse

As part of a school-based alcohol misuse prevention study, questionnaires were ad ministered to 2,589 fifth and sixth grade students to determine levels of use of alcohol, marijuana, and cigarettes, intentions to use these substances, and problems resulting from alcohol misuse. The questionnaire also included 45 items concerning susceptibil ity to peer pressure, self-esteem, and health locus of control. These 45 items were factor analyzed separately for two groups formed by random assignment. Six factors were identified which were both internally consistent and replicable, and indices were constructed. The indices measuring susceptibility to peer pressure, self-esteem, and internal health locus of control were significantly and negatively correlated with most of the substance use, misuse, and intention items, and an external health locus of con trol index was not significantly related to most of the substance use, misuse, and inten tion items. The "Susceptibility to Peer Pressure" index correlated more highly with the adolescent substance use, misuse, and intention items than the self-esteem or the health locus of control indices, and it had the highest alpha coefficient. Implications for the design of school-based substance abuse prevention programs are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68065/2/10.1177_109019818701400207.pd
