This study is the first study in Indonesia that examines the factors that influence financial anxiety. Financial anxiety is a negative psychological impact where there is a decrease in various aspects so that, in total, it causes stress levels to jump. This study focuses on adolescents who live in Surabaya, which, based on BPS data, the city of Surabaya has the largest population in East Java and is dominated by adolescents. This study aims to determine the effect of income, debt, financial knowledge, and financial satisfaction on financial anxiety. Data were collected by distributing online questionnaires with random sampling methods to 154 respondents. Then, data were tabulated in excel, analyzed and processed using multiple linear regression in SPSS. The result of this study indicates that none of the independent variables affects financial anxiety. This is presumably due to the lack of public knowledge about financial anxiety, especially among Surabaya adolescents. Few studies examine financial anxiety as the dependent variable, which thought to cause limited public knowledge about this topic. Therefore, this study is expected to increase knowledge, literacy, and public awareness regarding financial anxiety, especially to adolescents in Surabaya.

Despite the existing evaluation of the sampling options for periodical media content, only a few empirical studies have examined whether probability sampling methods can be applicable to social media content other than simple random sampling. This article tests the efficiency of simple random sampling and constructed week sampling, by varying the sample size of Twitter content related to the 2014 South Carolina gubernatorial election. We examine how many weeks were needed to adequately represent 5 months of tweets. Our findings show that a simple random sampling is more efficient than a constructed week sampling in terms of obtaining a more efficient and representative sample of Twitter data. This study also suggests that it is necessary to produce a sufficient sample size when analyzing social media content.
