Entitativity, an individual’s recognition of a social unit as a group, is a fundamental group characteristic. However, past entitativity measures have not demonstrated their psychometric validity. We create and demonstrate initial psychometric validity for a new measure of entitativity as well as several of its antecedents. We demonstrate convergent and divergent validity of our entitativity measure (and the antecedents) in three studies of online and face-to-face groups in which people either observe a group or are members of a group. Results demonstrate that our measures of entitativity and its antecedents are robust across different group contexts. We also discuss the implications of the results of this research to advance entitativity theory.

The very early onset of smoking predicts numerous health problems. The authors conducted the first test of one risk model for elementary school age smoking, known as the acquired preparedness (AP) model of risk, in a cross-sectional sample of 309 5th grade children. The model posits that (a) impulsivity-related personality traits contribute to risk for a variety of risky, maladaptive behaviors; (b) smoking expectancies confer risk only for smoking; and (c) the personality traits contribute to the formation of high risk expectancies for reinforcement from smoking, which in turn increases the likelihood of early onset smoking. The model was supported: the high-risk personality traits distinguished children engaging in any risky, maladaptive behavior from other children, and the smoking expectancies differentiated smokers from all other children. The relationship between personality tendencies to act rashly when experiencing intense positive or negative emotions and smoker status was partially mediated by expectancies for reinforcement from smoking. This model should be investigated longitudinally.

“Yet” is a school-based youth development program intended to introduce elementarygrade students to concepts of growth mindset, self-leadership, resilience and self-talk to promote healthy coping strategies to persist in tasks toward more positive educational outcomes.  Drawing from psychology, education, and management literature focusing on self-leadership, the “Yet” program encourages interaction and internalization of concepts such as “growing the brain,” and “stinkin’ thinking,” while modeling how to reframe set-backs to things students have not mastered…”yet,” and practicing adaptive self-talk to promote coping and persistence.  This unique program holds promise because it is approximately 30 minutes long, occurs within the context of a regular school day, and can be implemented with a high measure of fidelity because it is script-based.  The success of the program may be augmented by principal and teacher support along with online videos.
