Human Reactions to Uncontrollable Outcomes: Further Evidence for Superstitions Rather Than Helplessness

Recent research has shown superstitious behaviour and illusion of control in human subjects exposed to the negative reinforcement conditions that are traditionally assumed to lead to the opposite outcome (i.e. learned helplessness). The experiments reported in this paper test the generality of these effects in two different tasks and under different conditions of percentage (75% vs. 25%) and distribution (random vs. last-trials) of negative reinforcement (escape from uncontrollable noise). All three experiments obtained superstitious behaviour and illusion of control and question the generality of learned helplessness as a consequence of exposing humans to uncontrollable outcomes.

Predictors of anxiety and depression among newly diagnosed people living with HIV: A longitudinal study

This longitudinal study examined whether past resilience and internalized stigma predicted anxiety and depression among newly diagnosed Spanish-speaking people living with HIV (PLWH). We also analyzed whether coping strategies mediated this relationship. Data were collected at two time points from 119 PLWH. Approximately a third of participants had scores indicative of anxiety symptoms, the same result was found for depressive symptoms. Structural equations modeling revealed that 61% of the variance of anxiety and 48% of the variance of depression 8 months after diagnosis was explained by the proposed model, which yielded a good fit to data. Anxiety and depressive symptoms were significantly and negatively predicted by positive thinking, thinking avoidance, and past resilience, and positively predicted by self-blame. Additionally, anxiety was positively predicted by internalized stigma. Past resilience negatively predicted internalized stigma, self-blame, and thinking avoidance and it positively predicted positive thinking. Internalized stigma positively predicted self-blame. Moreover, internalized stigma had a significant indirect effect on anxiety symptoms through self-blame, and past resilience had significant indirect effects on anxiety symptoms and depressive symptoms through internalized stigma and coping. The results point to the need for clinicians and policy makers to conduct systematic assessments and implement interventions to reduce internalized stigma and train people living with HIV to identify and use certain coping behaviors.     

Psychosocial and health consequences of adolescent depression in Black and White young adult women.

Depression in adolescent girls may result in negative consequences in young adulthood. The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to 1,727 Black and White girls ages 16 to 18 years who participated in the National Heart, Lung, and Blood Institute's Growth and Health Study. Three years later, women in the depressed groups were more likely to be current smokers, had attained a lower level of education, and reported lower self-worth relative to the nondepressed group. Body dissatisfaction, eating concerns, and loneliness were greater in the depressed groups. Relative to Black women, White women who were moderately depressed during adolescence reported more health care services utilization in young adulthood. Prevention efforts for depressed adolescents should be broadly focused to improve young adult outcomes.
