A longitudinal examination of stress generation in depressive and anxiety disorders

The current study compared two competing theories of the stress generation model of depression (stress causation vs. stress continuation) using interview-based measures of episodic life stress, as well as interpersonal and noninterpersonal chronic life stress. We also expanded on past research by examining anxiety disorders as well as depressive disorders. In addition, we examined the role of neuroticism and extraversion in these relationships. Participants were 627 adolescents enrolled in a two-site, longitudinal study of risk factors for depressive and anxiety disorders. Baseline and follow-up assessments were approximately one year apart. Results supported the stress causation theory for episodic stress generation for anxiety disorders, with neuroticism partially accounting for this relationship. The stress causation theory was also supported for depression, but only for more moderate to severe stressors; neuroticism partially accounted for this relationship as well. Finally, we found evidence for interpersonal and noninterpersonal chronic life stress continuation in both depressive and anxiety disorders. The present findings have implications regarding the specificity of the stress generation model to depressive disorders, as well as variables involved in the stress generation process.     

Giving Psychology Away: A Personal Journey

ABSTRACT— In this autobiographical essay, I trace the origins of my passion for communicating with the public about mental health and the behavioral sciences and make a case for spreading such passion among psychologists. I also describe the circuitous route that led to my unlikely 4-year tenure as editor-in-chief of Psychology Today magazine and describe some of the inner workings of this New York–based, commercial enterprise—formerly the property of the American Psychological Association. I made some progress in that role to return the magazine to its scientific origins, providing an outlet for hundreds of scientists and practitioners to speak directly to millions of Americans about their work. This is an essential task, I argue, if our field is to flourish. I also detail my departure as editor-in-chief of Psychology Today and describe the magazine's rapid return to "pop" status. Media sources do not automatically welcome participation by clinicians or behavioral scientists. Through a contingency analysis, I suggest ways of improving our ability to interface successfully with media professionals.     

Constructive thinking: a broad coping variable with specific components

The structure of constructive thinking and the development of an instrument for measuring it, the Constructive Thinking Inventory (CTI), were discussed. Scales were derived from a factor analysis of an item domain of people's everyday automatic thinking. When the CTI and other tests were factor analyzed, separate intellective and nonintellective factors were found, with the CTI loading more strongly on the nonintellective factor than any other test. Only measures of IQ loaded on the intellective factor. The global constructive thinking scale correlated significantly with success in work, love, social relationships, and in maintaining emotional and physical well-being, but not with academic achievement, the only criterion with which the measures of IQ correlated strongly. The patterns of correlations between the CTI scales and the various criteria as well as the factor analysis demonstrated that the construct of constructive thinking is differentiated as well as integrated.     

Does aggregation produce spuriously high estimates of behavior stability?

A number of arguments as to why aggregation produces spurious correlations are considered and shown to be specious. A series of computer-simulated studies, claimed by H. D. Day and his colleagues to demonstrate that aggregation produces artifactually high stability coefficients, was shown to involve bizarre distributions and inappropriate conclusions. Nevertheless, their data actually indicated the potency of aggregation in detecting whatever empirical relations they built into their data. This was not true of their analyses of their unaggregated data, which, as a result of a high level of noise of measurement, failed to enable them to detect anomalies in their data. No amount of aggregation produced evidence of stability in its absence. It is concluded that aggregation provides a powerful tool for reducing error of measurement and for establishing and enhancing generality as well as stability in measurement. Although there is nothing intrinsic in aggregation that fosters spurious correlations, it like any other technique can be used wisely or foolishly. In order to achieve the former, aggregation must be guided by psychometric principles and theoretical considerations. A procedure guaranteed to achieve the latter is to simply aggregate whatever can be assigned a common label.     

Perception of cross-situational consistency

Eighty-eight undergraduates rated the degree of relation in each of 21 pairs of items that described behavior in the domains of conscientiousness, friendliness, and extraversion. In these three domains, estimates of relations by the average subject correlated, respectively, with actual empirical relations, .63, .58, and .40. Relations corresponding to correlations between .10 to .20 could be significantly distinguished by subjects from relations in the range of .00 to .10 in two of the three domains. The confidence that individuals placed in their perceptions varied directly with the accuracy of their judgments against the empirical criterion. In addition, subjects were more confident of what they perceived to be extreme relations in both directions than of intermediate relations, and they also tended to be more confident of their judgments of strong positive relations than of zero relations. They exhibited an intuitive awareness of the effect of aggregation over occasions and items of behavior on the magnitude of cross-situational relations and the demonstration of traits. They also reported using reasonable strategies in arriving at decisions. Far from being inveterate trait believers, as some have suggested, subjects' intuitions paralleled psychometric principles in several important respects when assessing relations between real-life behaviors.
