Abstract

This study aims to analyze the impact of farmer?s attitude and perceived quality to farmer?s satisfaction and its effect on brand loyalty in using Bisi-2 hybrid corn seeds in Tekasire village. This study uses causal analysis methods, thus multiple linear regression is utilized to analyze answer the research question. Before the data is analyzed, there will be some tests apply to the data, this procedure is called as classical assumption tests. The result revealed that perceived quality and customer attitude significantly and positively affect customer satisfaction of farmers toward Bisi-2 corn seed and so customer satisfaction affects brand loyalty, however direct relationship between perceived quality and brand loyalty is weak or not significant and so with relationship between customer attitude and brand loyalty. Bisi-2 corn seed sellers is suggested to pay attention on customer satisfaction as first priority since it is the only way to make their customers become loyal to their brand. Meanwhile customer satisfaction can be achieved by increasing customer positive attitude toward their product and perceived quality from customer point of view.

Abstract

Perceived Behavioral Control (PBC) is a key construct in the Theory of Planned Behavior (TPB) that plays an important role in predicting adherence to lifestyle changes among patients with coronary artery disease (CAD). Although the role of PBC has been widely discussed in health behavior research, no instrument has been specifically developed and validated to measure PBC in patients with cardiovascular disease (CVD), particularly CAD. This study used the Rasch analysis approach to evaluate the construct validity and reliability of the Perceived Behavioral Control Scale Related to Cardiovascular Disease (PBCCVD). This was a cross-sectional study involving 92 post-hospitalization CAD patients selected through convenience sampling. The PBCCVD instrument consists of 22 items using a 4-point Likert scale, developed based on TPB theory and previous studies and validated by experts. Data analysis was conducted using Winsteps software, covering reliability, separation, fit statistics, and unidimensionality. The instrument demonstrated high reliability (Cronbach's alpha = 0.86; item reliability = 0.94; person reliability = 0.86). The item and person separation indices were 4.18 and 2.74, respectively. All items met the fit criteria. The explained variance was 34.9%, and the eigenvalue of the first contrast was 2.6054, indicating a possible additional subdimension. The PBCCVD is a reliable and reasonably valid instrument for measuring perceived behavioral control in CAD patients. Although there is an indication of another underlying dimension, the instrument can still be effectively used in both clinical and research settings.
