This study aims to predict adherence to diabetic treatment regimens and sustained diabetic control. During two clinic visits that were 2 months apart, 63 adult outpatients completed measures of diabetic history, current treatment, diabetic control, adherence, and self-efficacy about adherence to treatment. Results showed that self-efficacy was a significant predictor of later adherence to diabetes treatment even after past levels of adherence were taken into account. Posttest levels of adherence in turn were significantly associated with posttest %HbA1c after control for illness severity. A stepwise multiple regression to predict %HbA1c at post entered pretest measures of diabetic control, treatment type, and self-efficacy, which together predicted 50% of the variance. Results are related to self-efficacy theory and implications for practice are discussed.

Ostracism, a complex social phenomenon, involves both targets (ostracized individuals) and sources (ostracizers). The current experiment redressed a gap in the ostracism literature by devising a novel, three-phase paradigm to investigate motivated ostracizing. In the current study, 83 females were assigned to one of four conditions during a Cyberball game: motivated sources chose to ostracize an obnoxious fellow player, induced sources ostracized a fellow player at the behest of the experimenter, targets were ostracized, and included participants received the ball proportionately. Analysis of participants' primary needs, emotions, ratings of their co-players, and behavior toward their co-players indicated that being the target of ostracism was a robustly aversive experience. Both motivated and induced sources reported fortified control. Moreover, a motive for ostracizing influenced source experience: induced sources experienced greater levels of negative moral emotion and behaved more prosocially toward their target than motivated sources. The flexibility and demonstrated impact of this novel paradigm adds to the toolkit available to researchers interested in expanding insight into the psychological processes underlying, and the motivational and behavioral outcomes of being, a source of ostracism.
