A temporal investigation of the direct,interactive, and reverse relations between demand and control and affective strain

Abstract

Few studies have tested how stressors affect outcomes over time. We sought to extend the literature by means of a longitudinal study testing for direct, interactive, and causal relations between demands and control and affective strain. We extended prior work testing causal relationships for Karasek's (1979 Karasek, R.A. Jr. 1979. Job demands, job decision latitude, and mental strain: Implications for job redesign. Administrative Science Quarterly, 24: 285–307. [Crossref], [Web of Science ®] , [Google Scholar]) Job Demand-Control (JDC) model by examining both the effects of demands and control on strain and in turn the effects of strain on demand and control. We tested our hypotheses using hierarchical linear modelling with a military sample of 1539 soldiers who completed six waves of survey data at 3-month time lags. The results replicate earlier cross-sectional studies reporting effects of work characteristics on strain; however, in our study these effects did not persist past three months. The results also provide evidence for reverse causal effects such that higher strain was associated with higher subsequent work overload and lower control over a six month time period. Similar to past research, we did not find support for the interactive effects of work overload and control on strain. We discuss the implications of our findings for theory and practice (such as the optimum time for applying interventions during the management of change), especially in terms of understanding the specific time lags for different stress–strain associations and the need for additional theories to explain reverse relationships.     

The Implications of Demographic-Specific Inflation Rates for Trends in Real Educational Wage Differentials

We use data from consumer expenditure surveys to investigate the impact on trends in real wage differentials of using group-specific price indexes. We find that inflation rates decrease monoton-ically with the education of the household head throughout the 1970s and early 1980s, and real educational wage differentials, calculated using education-specific price indexes, widened somewhat more than nominal differentials. We also find that differences by education level in fuel and energy consumption, whose relative prices increased during the 1970s, account for the majority of the educational index differences.

Mexican-American families: A psychoeducational approach for addressing chemical dependency and codependency

Chemical dependency and codependency are often referred to as family problems, and the ways in which families frame these problems may be influenced by their ethnic and cultural background. Increased efforts are being made to help families understand the problems that arise from alcohol and other drug abuse by utilizing approaches that take into consideration their unique cultural aspects. This article reviews some of the ways in which Mexican-American families, in particular, may view chemical dependency and codependency. More importantly, it describes the cultural adaptation of a psychoeducational program to help. Mexican-American parents, primarily mothers whose children are drug involved or who are considered to be at risk for drug use, better address these problems.     

Chinese families in transition: Cultural conflicts and adjustment problems

Challenged to cope with two different cultures, Chinese American immigrant families face many stressors and conflicts. Such difficulties faced by these individuals usually stem from language, religious, and value differences. Furthermore, family members are faced with role and status changes due to differing rates and levels of acculturation. As a result, there is a great need for mental health services. However, due to cultural barriers, mental health services are not accessible nor acceptable to many Chinese Americans. Effective intervention strategies which integrate the Chinese cultural values and norms with psychotherapy are recommended.     

USES OF CHILDREN'S MAKE-BELIEVE PLAY IN FAMILY THERAPY:THEORY AND CLINICAL EXAMPLES

A theoretical framework for developing, describing and analyzing family-therapeutic techniques involving make-believe play is presented and illustrated by clinical examples. This theoretical framework includes specifications of the therapeutic goals served by the technique and its procedural details (the therapist's position and roles, the method of intervention, the sources of play content and means, and the amount of planning) and an analysis of its rationale (the properties of the make-believe play involved, the targets of the intervention in the family system, the expected changes and their causes). This framework draws on a definition of the concept "make-believe play," a model for the analysis of make-believe play symbols and a model of family systems, which are briefly sketched in this article, preceding the presentation of the theoretical framework itself.
