The purpose of this dissertation is to develop and evaluate an expanded spokesperson credibility model to address issues uncovered in Ohanian's (1991) study about linkages between spokespersons ' credibility and consumers ' purchase intentions. Based on Tajfel's social categorization theory (1981), 12 hypotheses were developed to test direct and indirect relationships between spokesperson's credibility and purchase intentions.
The sample for the study consisted of 1,162 respondents 82.9% students and 17.1% nonstudents; 48.2% males and 51.4% females; 31.3% Caucasian (American); 24.5% Cuban (American); 19.6% other Hispanics and 22.5% other ethnic groups. The data were collected .by having respondents either view a video tape or listen to an audio tape in a classroom or shopping mall setting. The respondents were told that they would hear a spokesperson presenting a message. After listening to the message they would then be asked to complete a questionnaire.
The spokesperson credibility model was tested using covariance structure analysis as implemented in the LISREL software. A series of ANOVAs were used to test the impact of the moderating variables on purchase intentions.
The findings indicate that Ohanian's (1991) credibility constructs i.e., attractiveness, trustworthiness, and expertise are significantly related to purchase intentions. In addition, the following interactions were found to be statistically significant:
