On the stress/parasuicide or parasuicide/stress relationship.

The question of whether high stress leads to attempting suicide (parasuicide) or suicide attempters are more likely to report high stress was examined in a one-year follow-up study of 98 persons, 47 of whom had attempted suicide. Cross-lagged panel correlations between stress and parasuicide provided both concurrent and predictive validity that stress as measured by life changes leads to parasuicide. A high relationship between stress at baseline and stress at follow-up provided support for the notion that some individuals experience chronic stress and that such individuals may be the ones at risk for future suicide attempts.

Effects of number of pre-exposures on sucrose taste aversion in weanling rats.

Weanling rats, 20 days old, received 0, 1, 2, 4, or 8 pre-exposures to 12% sucrose prior to a single pairing of sucrose with an intraperitoneal injection of lithium chloride (LiCl; 3.0 mEq of a .15Msolution) or distilled water (20 mg/kg). Testing for sucrose taste aversion with a 2-bottle-choice procedure on 9 test trials reliably showed that increasing numbers of pre-exposures to sucrose directly attenuated taste aversion effects in the LiCl-injected groups but did not appreciably affect intake performance in the distilled water-injected groups. Comparisons between the injection conditions yielded reliable evidence for sucrose taste aversion at each pre-exposure level. These results show that flavor stimulus pre-exposures reliably attenuate subsequent taste aversion in weanling rats as had previously been reported for adult rats.

Mediating factors in the relationship between life stress and suicide attempting.

The present study examined male suicide attempters and a control population of psychiatric patients in an effort to determine the importance of life stress and locus of control as factors in suicide attempting. The parasuicide group was found to be younger, less psychotic, and more depressed than the psychiatric group. Age was found to mediate the relationship between stress and suicide attempts; among older subjects, stress was greater in the attempt group than in the control group, but no difference in stress levels was found for younger subjects. With respect to locus of control, the results indicated that suicide attempters did not differ from psychiatric patients on degree of externality, although a relationship between stress and parasuicide was found for those individuals identified as congruent externals.
