Fitness correlates of obligatory versus health motives for exercise: An examination of men in the military

Objectives

To examine quantity of exercise and motives for exercise as predictors of men in the military’s health and fitness level.

Design

Participants completed a survey to address research questions of interest.

Methods

One-hundred and fourteen men who were active duty Air Force members, with a mean age of 31.43 years (SD = 7.43) and an average military time in service of 10.66 years (SD = 7.75), completed a modified version of the Reasons for Exercise Inventory, a survey assessing their quantity of exercise, and reported their most recent score on their Air Force Fitness Test.

Results

Correlational analyses indicated a relation between quantity of exercise and men’s score on the Air Force Fitness Test and a relation between intrinsic motives for exercise and quantity of exercise. Intrinsic motivation was found to moderate the relation between quantity of exercise and men’s health and fitness score.

Conclusions

Men in the military who exercise because of their military obligation are less likely to score high on the Air Force Fitness Test than are men who are motivated to exercise for health benefits.     

Why Doesn't Parental Alienation Occur More Frequently? The Significance of Role Discrimination

Approximately two thirds of divorced families develop co-parenting relationships that are more or less effective. Of the approximately one third of divorces that do not evolve into effective co-parenting, a subset deteriorates into parental alienation. Classical Balance theory predicts parental alienation as a normative outcome in divorcing and divorced families. Discriminating between their roles as spouses and parents allows separated and divorced couples to avoid alienation outcomes. Elevated anxiety, however, may interfere with these discriminative responses, and lead parents into stereotyping each other. This article proposes a two-dimensional model of parental estrangement-alienation addressing variations in anxiety and stereotyping. Interventions for reducing the effects of estrangement and alienation are also identifed and discussed.     

Trust of an Automatic Ground Collision Avoidance Technology: A Fighter Pilot Perspective

The present study examined the antecedents of trust among operational Air Force fighter pilots for an automatic ground collision avoidance technology. This technology offered a platform with high face validity for studying trust in automation because it is an automatic system currently being used in operations by the Air Force. Pilots (N = 142) responded to an online survey which asked about their attitudes toward the technology and assessed a number of psychological factors. Consistent with prior research on trust in automation, a number of trust antecedents were identified which corresponded to human factors, learned trust factors, and situational factors. Implications for the introduction of novel automatic systems into the military are discussed.     

Multi-Couple Group and Self-Directed PREP Formats Enhance Relationship Satisfaction and Improve Anger Management Skills in Air Force Couples

This study examined the effectiveness of delivering the Prevention and Relationship Enhancement Program (PREP) to volunteer couples in the U.S. Air Force in either a six-week instructional multi-couple group condition or a self-directed book condition. A standardized pre/post protocol was employed and outcomes included relationship satisfaction and anger management skills, two known risk factors for partner maltreatment. Significant improvement was found for the group condition in both relationship satisfaction and anger management skills, but only for anger management skills in the self-directed book condition. Finally, the group condition reported greater program satisfaction. Implications are discussed.     

Maximizing the discriminating power of a multiple-score test

Maximizing the discriminating power of a multiple-score test involves maximizing the homogeneity of each subtest and minimizing the correlations between subtests. A method is presented for constructing such tests from items whose intercorrelations are not too high. Under certain restrictions the saturation, defined as the proportion of inter-item covariance to total variance, is maximized for each subtest. The nucleus of each subtest is three items with high covariancesinter se. All items which will lower the saturation are discarded; the one item is added which will maximize the saturation of the resultant test. This process is repeated until all the items are included or discarded for that subtest. If the correlation between any such subtests approaches the geometric mean of their saturations, their items form a new pool for one or more subtests. Formulas are presented for deciding which items to eliminate in order to reduce further the correlations between subtests.This research was supported in part by the United States Air Force under Contract AF 33(038)-10588 with Human Resources Research Center, Lackland Air Force Base, San Antonio, Texas.

Air Force Commanders' Disciplinary Decisions on Spouse Abuse Cases

ABSTRACT

Inconsistencies exist among Air Force commanders when disciplining spouse abuse offenders, possibly owing to inadequate training, unclear role expectations, conflicting policy statements, or personal biases. This situation may lead to inappropriate decisions, further endangering victims and negatively impacting mission readiness. A sample of 624 Air Force squadron commanders was surveyed to measure how their perceived role and operations tempo affect their disciplinary decisions on two abuse scenarios. The study tested role and decision-theory concepts. Statistical results supported role theory in the predicted direction, and decision theory, but in the opposite direction hypothesized. Implications for theory, practice, and policy development for the military are discussed.     

A statistical critique of the USAFI tests of general educational development

Data resulting from the administration of the USAFI Tests of General Educational Development to more than 1000 junior Air Force officers have been statistically analyzed to indicate the reliability of these tests, their correlation with school achievement, the comparability of their intercorrelations with intercorrelations among grades in school subjects, their capacity for differential diagnosis, their factorial composition, and their average item-test correlations. In the light of these findings and the finding that there is a low gradient between achievement on these tests and amount of formal education among these officers, the tests have been evaluated as possessing the practical validity suggested by their face validity for selection of young Air Force officers for assignment to study at civilian colleges and universities.Paper read before the National Council on Measurements Used in Education, Atlantic City, New Jersey, February 24, 1948.

Can I see the real me? Leadership ability and the better-than-average effect

Military organizations typically emphasize the importance of leadership. The quality of military leadership might be inhibited because individuals tend to overestimate their respective leadership abilities. We hypothesized that military professionals generally overestimate how well they lead compared to their peers (Hypothesis 1). We also hypothesized that an egocentric bias, where self-ratings are weighted more strongly than other-ratings, contributes to this better-than-average effect (Hypothesis 2). The results obtained across two studies supported both hypotheses. Most notably, 242 of 251 United States Air Force Academy cadets and 31 of 34 United States Air Force officers rated themselves as above average compared to their peers. The obtained results have important implications for understanding the better-than-average effect generally and leadership in military and nonmilitary organizations.     

Computer-aided analysis of in-flight physiological measurement

An Examination of Situational Constraints in Air Force Work Settings

Our investigation involved the measurement of constraints in a variety of Air Force work settings and the examination of hypothesized relationships between these constraints and performance, affective reactions, and reenlistment plans in seven Air Force occupational specialties. The severity of constraints was found to be mild across the specialties investigated. The presence of constraints tended to be associated with decreased satisfaction, increased frustration, and increased thoughts of leaving the Air Force. However, contrary to expectations, constraints were not related to either performance or intentions to leave.     

Large sample validations of three general predictors of pilot training success

This article addresses one of the perennial problems of pilot selection research: obtaining an adequate sample size for reliable statistical analysis of predictive validity. Results from three studies involving the same computerized tests of instrument comprehension and psychomotor ability were combined in a meta-analysis to determine whether the validities of these tests generalized across three contexts. These were Royal Air Force and Turkish Air Force fixed-wing pilot training and British Army Air Corps rotary-wing pilot training. In this article, we discuss the adequacy of samples for estimating the validity of the tests, and the persistence of predictive validity to later stages of training as shown by British Army Air Corps data. Reference is also made to data from a fourth independent study of Qantas pilot training.

Testing message diffusion in harmonic logistic curves

The growth of a population of knowers of a message was studied to test a human interactance hypothesis. The conditions investigated involvedpeople interacting in time, with the population pairing off randomly (i.e., determined by many, small, different influences) and transferring an attribute (i.e., an all-or-none act) at either a steady rate or a waning rate, subsequent to the originating stimulus. The mathematical expressions for these pre-conditions were the differential equations for the linear logistic for steady acting and the harmonic logistic for waning acting. Variant forms of these curves were developed. Two exploratory experiments, or pretests, comprised launching a coffee slogan in a town and imitating a badge wearer in a boys' camp. Since the activity rate waned harmonically in both cases, the harmonic logistic fit best in both the town and the camp as expected by the hypothesis.A paper read before Section K sponsored by the Committee on Social Physics of the AAAS Conference in Boston, December 30, 1953.

Evaluation of an Air Force Child Physical Abuse Prevention Project Using the Reliable Change Index

Three hundred and seventy-nine parents at 25 Air Force bases participated in a collaborative child physical abuse prevention project designed by the United States Air Force Family Advocacy Program and Father Flanagan's Boys' Home (Boys Town). These participants were active duty or civilian employee parents and their spouses who completed the Boys Town Common Sense Parenting ® program as part of a comprehensive prevention effort. We hypothesized that participants would report decreased child behavior problems, improved relationships with family members, and reduced risk for child physical abuse after attending parenting sessions. Results supported this hypothesis. The data were also analyzed to determine the frequencies of individual parents who made statistically reliable changes on the dependent measures using Jacobson's Reliable Change Index. Nineteen to 30% of the participants reported significant improvement in the areas assessed. Parents who improved in abuse risk were at a higher level of risk and were less satisfied with family relationships prior to their participation than those who did not change. Implications for prevention of child physical abuse and future directions for research are discussed.     

Development and convergent validation of a methodology for estimating cross-job retraining times

Cross-jobtransferability of skills is defined in terms of the ease with which individuals can apply knowledge and skills acquired in a previous job in learning to perform a new job. This study reports the development of a prototype methodology for estimating retraining times based on analyses of transferability of skills. Using this methodology which assesses interjob similarity in task content and task learning time, times to retrain across 41 different U.S. Air Force enlisted jobs were estimated. Convergent validities of retraining time estimates were tested in terms of correlations with differences in jobs': (a) general job learning difficulty, and (b) aptitude requirements. Results supported predictions that cross-job retraining time would be longer (a)into jobs that generally aremore difficult to learn, (b)from jobs that generally areless difficult to learn, and (c) across jobs having different, rather than similar, aptitude requirements. Implications for training, human resources planning, and coping with increasingly rapid technological changes in the workplace are discussed.Research sponsored by the Air Force Office of Scientific Research/AFSC, United States Air Force, under contract F49620-87-R-0004.

Harold Garfinkel and Edward Rose in the early years of ethnomethodology

This article documents the beginning of the intellectual companionship between the founder of ethnomethodology, Harold Garfinkel, and Edward Rose, who is most often associated with his program of “ethno-inquiries.” I present results from archival research focusing on the contacts and collaborations between Rose and Garfinkel in the years 1955–1965. First, I describe the review process for Rose and Felton's paper, submitted to the American Sociological Review in 1955, which Garfinkel reviewed and after Rose's rebuttal recommended for publication. The paper induced Garfinkel to write an extensive commentary that has remained unpublished. Second, I discuss the 1958 New Mexico conference sponsored by the Air Force, which was an opportunity for Rose and Garfinkel to work together on topics related to common-sense knowledge and scientific knowledge. Third, I give an overview of the ethnomethodological conferences in 1962 and 1963, supported by an Air Force grant written collaboratively by Rose and Garfinkel. Here I focus primarily on Rose's research on “small languages,” which stimulated many discussions among the early ethnomethodologists. Rose's work and exchanges with Garfinkel demonstrate the former's affinity for miniaturization as a research approach and search for ways to empiricize topics of sociological theory in locally observable settings.     

General resolution of correlation matrices into components and its utilization in multiple and partial regression

The derivation of multiple and partial regression statistics from uniqueness-augmented factor loadings, presented in the literature for orthogonal factor solutions, is generalized to oblique solutions. A mathematical rationale for the general case, without restriction to uncorrelated factors, is presented. Use of the general formulation is illustrated with a two-factor, seven-variable example.This report is based on work done under ARDC Project 7702, in support of the research and development program of the Air Force Personnel and Training Research Center, Lackland Air Force Base, Texas.

Review of psychomotor skills in pilot selection research of the U.S. military services

This review provides an historical perspective of the use of psychomotor, perceptual--cognitive paper-and-pencil, and automated tests for the selection of pilot trainees by the U.S. military services. Automated versions of vintage psychomotor tests (developed in the 1930s and 1940s) seem to be as predictive of military pilot/aviator performance today as in the past. The psychomotor tests receiving the most attention today are the Complex Coordination and Two-Hand Coordination tests originally developed by Mashburn and colleagues [correction of colleges] before World War II (Mashburn, 1934). These tests were significant predictors of Air Force and Navy pass--fail criteria in the past, and automated versions are similarly predictive today. The U.S. Army and Air Force are now using a combination of paper-and-pencil and automated psychomotor--cognitive tests for initial selection (Air Force) or helicopter assignment (Army). It appears that the Navy is considering the use of automated cognitive and psychomotor tests in a selection battery of the future.     

An IBM method for computing intraserial correlations

A method for computing intraserial correlations using a 602-A Calculating Punch, an 077 Collator, a 513 Gang Punch, and a 403 Tabulator is described. An example of the use of the procedure and an estimate of the time needed with each machine are given. This procedure is compared with another method, which makes use of a more powerful IBM machine.This research was supported in part by the United States Air Force under Contract No. AF 33(038)-25726, monitored by the Air Force Personnel and Training Research Center.

The mean and standard deviation of the distribution of group assembly sums

An interesting problem in linear programming is the group assembly problem which is mathematically equivalent to the general transportation problem of economics. Computer programs designed for the determination of exact and approximate optimal group assemblies have been available for some time. This paper presents formulas for the mean and squared standard deviation of the distribution of all possible group assembly sums. Computational techniques are presented and the results are related to those of the analysis of variance of ak-factor problem withn levels of each factor.This research was supported in part by the United States Air Force under Project No. 7713, Task No. 77232, and Contract No. AF 18(600)-1050, monitored by the Crew Research Laboratory of the Air Force Personnel and Training Research Center.
