To provide practitioners with useful information about how to promote proenvironmental behavior (PEB), a meta-analysis was performed on 87 published reports containing 253 experimental treatments that measured an observed, not self-reported, behavioral outcome. Most studies combined multiple treatments, and this confounding precluded definitive conclusions about which individual treatments are most effective. Treatments that included cognitive dissonance, goal setting, social modeling, and prompts provided the overall largest effect sizes (Hedge’s g > 0.60). Further analyses indicated that different treatments have been more effective for certain behaviors. Although average effect sizes are based on small numbers of studies, effective combinations of treatments and behaviors are making it easy to recycle, setting goals for conserving gasoline, and modeling home energy conservation. The results also reveal several gaps in the literature that should guide further research, including both treatments and PEB that have not been tested.

The primary objective of this research was to create a detailed characterization of human milk donors, including descriptive information about demographics and lifestyle, involvement with the milk bank, reasons for donating, problems encountered while breastfeeding and pumping milk, barriers to donating milk, affective experiences, and personal values. Data were collected via telephone interview of 87 donors and 19 nondonor controls. Few relationships were found between the descriptive information and amount of milk donated. Donors reported fewer problems pumping milk than nondonors. Strategies for recruiting new donors and strategies for increasing donation amounts are presented. J Hum Lact. 23(4):350-357.

We assessed implicit orientations towards power versus intimacy using the Thematic Apperception Test (TAT) and the Implicit Associations Test (IAT). In addition, we assessed explicit orientations using self‐report measures of dominance versus nurturance motives and extrinsic versus intrinsic values. Further, we assessed the rated self‐concordance and importance of power versus intimacy idiographic goals. The six measures formed four factors: motives/values, goals, IAT and TAT. We also assessed a variety of outcomes ranging from well‐being to choice in a social dilemma. All six predictors correlated with at least some outcomes, with the values measure being strongest predictor of the predominantly self‐report outcomes. We suggest that there is value in simultaneously considering old school and new school approaches to assessing implicit motives. Copyright © 2007 John Wiley & Sons, Ltd.
