3. Research Methodology The main objective of this study is "measuring Factors Affecting Green Purchasing Behavior". The research model of the current research is established on the basis of the Chen & Chang (2012) study as depicted in Figure 1. In this model Environmental concern and attitude, Perceived consumer effectiveness, Perceived seriousness of environmental problems, Perceived environmental responsibility and Perceived effectiveness of environmental behavior are independent variables; green purchasing behavior is a mediator variable and Green purchasing behavior is a dependent variableBefore the actual research, pre-test was performed to 30 consumers to test questions in order to get feedbacks from respondents and also to see the reliability and validity of the questions itself. The questionnaires were divided into two parts. First part was the general demographic questions such as gender, age, occupation and monthly expenses. There were also questions regarding the media, product and brand that respondents know about the green ad or activities as well the product and brand that they usually bought. The second part was questions to represent the dimension of green purchase behavior which consisted of 35 questions measured by 7 point likert scale. 4. Data screening and analysisThe 310 dataset were coded and saved into SPSS version 22.0 and analyzed using AMOS version 22.0, during the process of data screening for outliers, a final 304 dataset to be analyzed. Several statistical validity tests and analysis were then conducted such as reliability test and composite reliability tests, validity tests using confirmatory factor analysis (CFA) for construct validity, discriminant validity for multicollinearity treatment, descriptive analysis, correlation and structural equation modeling analysis using AMOS 22.0 (SEM). The step in SEM analysis is CFA analysis, measurement analysis, discriminant analysis, composite reliability analysis and direct indirect impact analysis (mediating effect), testing the fit for the hypothesized structural model, revised model, (Sentosa et, al., 2012). 4. Results• Demographic profile of the respondentsFrom the table 1.1 it is evident that out of the total 310 respondents, more than 27% are below 25 years of age group, maximum that is to say 39% are from age group of 26 years to 35 years. M Nearly 20% are from the age group of 36 years to 45 years and rest of the 15% is from age group of 46 years and above.
