End-stage renal disease (ESRD) and its treatment are generally considered to be highly stressful and the associated loss of control over important life dimensions is believed to induce widespread depression. This situation was employed as a "living stress laboratory" in which to test the reformulated learned helplessness theory of depression. Results indicated that reduced perceived control over a variety of life dimensions was importantly related to increased depression, although the attributional reformulation of helplessness theory was not supported. Moreover, reanalyses of these data from a social learning theory perspective indicated that perceived self-efficacy contributed uniquely to this negative correlation in addition to expectancies regarding response-outcome contingency (Rotter I-E scores). The hypothesis that the negative correlation between depression and perceived control might also be explained in terms of patients' psychological differentiation and the intrusiveness of ESRD was subsequently examined. Results revealed that perceived intrusiveness contributed uniquely to perceived control and to affect, indicating that perceived control and intrusiveness each contribute independently to mood. Surprisingly, a low prevalence of clinical depression was observed, contradicting the general consensus that helplessness and depression are unavoidable psychological sequelae to ESRD. These findings are equally applicable to several other chronic and life-threatened patient populations (e.g., cancer, cardiac, diabetic) and thus underline the need for a general theory of the emotional impact of illness.

The purpose of this study was to examine the effect of mood lability on anticipation timing performance. The influence of gender and stimulus speed on timing error was also analysed. Spectral analysis was used to quantify frequency of mood change. The within-subjects standard deviation was calculated as a measure of intensity of mood change. Thirty-eight physical education students (18 men; M = 23.8 yrs, SD = 2.1 and 20 women; M = 20.4 yrs, SD = 1.6) participated in this study. Mood changes were measured along the Pleasantness and Energetic dimensions of the Affect Grid. Performance was assessed using the Bassin Anticipation Timer. It was hypothesized that: the fast mood changers would incur greater timing errors than the slow mood changers, men would perform with less error than women, and stimulus speed would have a significant influence on timing error. / Mixed factorial ANOVAs with repeated measures on the last factor were utilized to compare mean timing error scores: constant error, absolute error, variable error, and total error, over two levels of frequency of mood change (fast/slow) and intensity of mood change (high/low) groups, two levels of gender (men/women) and four levels of stimulus speed (5/10/15/25 mph). Alpha was set at the.05 significance level for all statistical comparisons. Results showed that intensity of mood change had a significant influence on anticipation timing performance, frequency of mood change factor did not have a significant effect on timing error, men performed with less variability than women and stimulus speed had a significant influence on anticipation timing. The Profile of Mood States (POMS) results, showed that women scored lower on the negative mood states than men. Total mood disturbance for both men and women showed no significant relationship to the timing error scores.
