The Moderating Effect of the Type A Behavior Pattern and Locus of Control upon the Relationship Between Change in Job Demands and Change in Psychological Strain
研究了工作需求变化与心理压力变化的关系，发现A型行为模式和控制点对此关系有调节作用，其中A型人在需求增加时压力增加较少。
This paper examines (1) the relationship between changes in job demands and changes in psychological strain across time, and (2) the moderating effect of the Type A behavior pattern (TABP) and locus of control, or internality-externality (I-E) on this relationship. TABP and I-E were hypothesized to moderate job demands because they appear as factors likely to affect the longer-term coping patterns of individuals, or coping styles. Among the job demand variables, increases in qualititative "low-load" were most strongly predictive of increases in psychological strain. Significant moderating effects were observedfor both TABP and I-E. With the TABP, a uniform pattern offindings emerged in that all the significant partial correlations were negative in direction, indicating that where job demands increased, Type As experienced less psychological strain than Type Bs. With I-E, however, the direction of the partial correlations varied dependent on the type of job demand.
