Description
This study investigates how well prominent behavioral theories from social psychology explain green purchasing behavior (GPB). I assess three prominent theories in terms of their suitability for GPB research, their attractiveness to GPB empiricists, and the strength of their empirical evidence when applied to GPB. First, a qualitative assessment of the Theory of Planned Behavior (TPB), Norm Activation Theory (NAT), and Value-Belief-Norm Theory (VBN) is conducted to evaluate a) how well the phenomenon and concepts in each theory match the characteristics of pro-environmental behavior and b) how well the assumptions made in each theory match common assumptions made in purchasing theory. Second, a quantitative assessment of these three theories is conducted in which r2 values and methodological parameters (e.g., sample size) are collected from a sample of 21 empirical studies on GPB to evaluate the accuracy and generalize-ability of empirical evidence. In the qualitative assessment, the results show each theory has its advantages and disadvantages. The results also provide a theoretically-grounded roadmap for modifying each theory to be more suitable for GPB research. In the quantitative assessment, the TPB outperforms the other two theories in every aspect taken into consideration. It proves to 1) create the most accurate models 2) be supported by the most generalize-able empirical evidence and 3) be the most attractive theory to empiricists. Although the TPB establishes itself as the best foundational theory for an empiricist to start from, it's clear that a more comprehensive model is needed to achieve consistent results and improve our understanding of GPB. NAT and the Theory of Interpersonal Behavior (TIB) offer pathways to extend the TPB. The TIB seems particularly apt for this endeavor, while VBN does not appear to have much to offer. Overall, the TPB has already proven to hold a relatively high predictive value. But with the state of ecosystem services continuing to decline on a global scale, it's important for models of GPB to become more accurate and reliable. Better models have the capacity to help marketing professionals, product developers, and policy makers develop strategies for encouraging consumers to buy green products.

Description
Research on psychological help seeking has continued to grow as the field of psychology has expanded. Much of the research is often variable driven and assumes this construct is a global construct. The current study used the Theory of Planned Behavior to provide a theory based approach to understanding psychological help seeking intention. Also, the theory was tested for three common presenting concerns: Anxiety or Depression, Career Choice Concerns, and Alcohol or Substance Use. Two samples of over 400 university students completed surveys for all three concerns. Results produced invariance across path loadings for the concerns being compared. When thinking about seeking psychological help, university students do not appear to consider the type of concern but do rely on attitude, stigma, and how much control and efficacy they have to address their problems on their own. Mean differences emerged for some variables in the model, but no meaningful mean differences were noted for gender. Overall, the variables used in the decision making process do not appear to consider concern when seeking help, but the beliefs about seeking help differ some. These results extend the Theory of Planned Behavior to consider the importance of an individual's ability to address their problem on their own. When considering psychological help seeking, college students have similar attitudes and beliefs about their ability to access mental health resources, their beliefs about stigma, ability to address their problems on their own, and their intention to seek help vary more by concern. The specific concerns being addressed does not appear to impact the weight each variable is given in the decision making process; attitude, stigma, and ability to solve the problem on their own appear to be the variables given greatest consideration.
