The validity of Mobley's (1977) model of employee turnover

Unlike earlier tests of an oversimplified version of this model, the validity of W. Mobley's (1977, Journal of Applied Psychology, 62, 237-240) original turnover model was fully investigated. Constructs that were neglected in prior studies were assessed and previously examined constructs were operationalized with more reliable measures. Measures of all constructs in Mobley's model were obtained from a survey of 192 hospital employees. Turnover data were collected a year following survey administration. Following the theoretical causal ordering of Mobley's constructs, each construct was regressed on all causally prior constructs. In general, each construct was accurately predicted by the linear combination of predictors representing its causal determinants. In the majority of instances, the best predictor of a model construct was the construct's immediate causal antecedent. Further, an alternative model was evaluated and compared with Mobley's model using path analysis.

DETERMINANTS OF R AND D COMPENSATION STRATEGIES IN THE HIGH TECH INDUSTRY

This study indicates that sales volume, stage in the product life cycle, profitability and turnover are all important predictors of the method and magnitude of financial rewards provided by high tech firms to R and D employees. The most favorable situational factors for R and D incentive compensation are a low sales volume high tech company, operating in the growth stage of the product life cycle, with high turnover rates, and capable of linking profitability to incentive rewards such as bonuses.     

Developmental influences on speech-motor equivalence: some implications for articulatory disordered children

The peak amplitude of EMG activity was measured from the orbicularis oris superior (OOS), orbicularis oris inferior (OOI) and masseter muscles for 3 normal 4-yr.-old children and compared to past data gathered on a group of articulatory disordered children, normal children, and adults. The 4-yr.-olds evidenced greater average peak EMG activity than the other groups, suggesting that speech-sound production becomes more efficient with maturation. Also, levels of variability obtained for the younger children were considerably smaller than for the normal speakers across the three muscles, showing that motor equivalence changes with age whereby the flexibility in the control of articulators increases. The coefficient of variation for the OOI muscle for the disordered children, however, was similar to that for the 4-yr.-olds, while the corresponding data for the other two muscles paralleled those for normal ones. These findings were interpreted as reflecting a delay in the development of speech-motor equivalence that affects certain muscles while sparing others.     

A LONGITUDINAL ANALYSIS OF BIOGRAPHICAL SUBGROUPS USING OWENS' DEVELOPMENTAL-INTEGRATIVE MODEL

The study examined the differential validity of 20 male and 14 female biographical subgroups in terms of 12 factor analyzed dimensions of postcollege experience. Owens' Developmental-Integrative Model hypothesizes that different subgroups of individuals with similar within-group early life experiences should exhibit significant differences (between-group) in a wide variety of life experiences. A sample of 1428 first-year college students were statistically grouped into 23 male and 15 female biodata subgroups after completing a standardized 118-item biodata form (Owens, 1968). Seven years later, a 97-item post-college experience inventory obtained scores for 484 of the original subjects on 12 factors of post-college behavior including job satisfaction, transition from college, personal and marital adjustment, and others. Significant univariate and multivariate differences were found between the biodata subgroups across the 7-year period. Implications for the validity of the D-I model are offered.     

HONESTY TESTING FOR PERSONNEL SELECTION: A REVIEW AND CRITIQUE

Paper and pencil predictors of employee theft are described and studies of validity, reliability, and adverse impact of these tests are examined. Validity studies for 10 tests were grouped into 5 categories: comparisons with polygraph examination results, correlations with admissions of past theft, predictive studies using future job behaviors as criteria, comparisons of shrinkage rates before and after the introduction of a testing program, and comparisons of test scores of groups known to be dishonest with groups representing the general population. While positive correlations were consistently found, a variety of methodological differences between studies were identified which make the direct comparison of test validities suspect. High reliabilities are consistently reported, and test score comparisons by race and sex generally report no differences. Ethical issues in honesty test usage are considered and future research needs are identified.     

Development of hand preference in the Colorado Adoption Project

A longitudinal study of the development of hand preference in 152 adopted and 120 nonadopted (control) infants measured in natural behavioral situations at both 12 and 24 mo. of age is reported. Significant developmental trends were observed for both increasing strength and direction of handedness. Less than 10% of the infants exhibited a clear preference at 12 mo. of age, whereas about 30% were lateralized at 24 mo., with more boys than girls being left-handed. In contrast, over 90% of the parents of these children (both biological and adoptive parents of the adopted children and parents of the nonadopted children) were lateralized. Perhaps because so few infants were lateralized at either age, parent-offspring resemblances were inconsistent and the number of significant parent/child correlations was about that expected on the basis of chance alone.
