The new issue of *Behaviour Research and Therapy* (vol. 48, #2, pp.
152-157) includes a study: “When self-help is no help: Traditional
cognitive skills training does not prevent depressive symptoms in people
who ruminate.”

The author is Gerald J. Haeffela.

Here’s the abstract:

[begin excerpt]

A randomized trial was conducted to test the efficacy of three self-
directed prevention intervention workbooks for depression.

Cognitively at-risk college freshmen were randomly assigned to one of
three conditions: traditional cognitive, non-traditional cognitive, and
academic skills.

Consistent with hypotheses, participants who were high in rumination and
experienced stress exhibited significantly greater levels of depressive
symptoms after completing the traditional cognitive skills workbook than
after completing the other two workbooks.

This pattern of results held post-intervention and 4 months later.

These findings indicate that rumination may hinder ones ability to
identify and dispute negative thoughts (at least without the help of a
trained professional).

The results underscore the importance of identifying individual
difference variables that moderate intervention efficacy.

They also raise concerns about the potential benefits of self-help
books, an industry that generates billions of dollars each year.
