Part I: Construct Development and Scale Creation
Choose a construct you would like to measure.

I picked self-confidence.

According to Brown (2004) self confidence is defined as one's ability to rely on themselves, to assert oneself socially, regarding what one thinks and possessing the skills to work independently, based on one's learning from personal experience and the ability to make use of prior knowledge. Self confidence measures include self efficacy, self esteem, knowledge and ability to work out problem situations and make informed and successful decisions, without relying on other individuals.

Scaling method for measuring Personal Self-Confidence will entail a survey consisting of 4 questions. Each question will aim at identifying the participant's own knowledge of how confident s/he is and the degree of confidence they have on their knowledge and their comfort level with the preferred style of working independently, as a self confident person.

Select and list five items used to sample the domain.
The Survey:
I am comfortable in developing a strategy to solve a problem on my own, before I approach someone else with more experience or knowledge. Yes No I prefer working independently, so that I can work out the details of completing tasks to my satisfaction. Yes No

In case of confusion, I investigate the issue myself, and then make an objective assessment about it and only believe this investigated information. Justify whether this is an interview or self-report instrument.

The scale measuring aspects of self confidence is a self report instrument. It is designed to be filled in as a survey. And the measurement will lead to a conclusion, based on participants responses regarding how much s/he is confident of own self.

Part II: Analysis and Justification

The survey instrument is supposed to determine the level of self confidence in the participant. All five of the statements focus on one's own self assessment regarding personal confidence and self-esteem. The statements measure the construct as defined. And has the robustness to capture the degree of confidence a person may have. Of course, much more detailed self confidence measuring scales and instruments have been developed before by researchers and scholars. But, for educational and practice purposes, the present scale will suffice to illustrate the purpose of the assignment i.e., apply the knowledge about scale development for research purposes. Several studies have investigated the impact of self-efficacy on consumer decision making and behavior , but none directly examines the role of Internet self-efficacy on attitudes and behavior intentions. Literature on self-efficacy also suggests that the construct has different meanings, depending on the context. For example, it may refer to a person's trust in another, another person's ability to perform a task, a person's judgment about a future event, or even a belief in a person's own ability (i.e., self-confidence) (Barbalet 1998). The feeling of confidence in one's own ability has been characterized as essential for any behavior to take place, because this belief serves as a form of self-assurance (Dequech 2000). With regard to using the Internet, personal confidence in an ability to understand, navigate, and content successfully should alleviate doubts and suspicions when dealing with user-generated content sites. In other words, people's level of Internet self-efficacy should relate to their heightened beliefs about the networking sites they encounter online. These beliefs in turn reflect a consumer's perceived capability to use the Internet accomplish tasks (Eastin and LaRose 2000). Then, "as Internet self-efficacy (i.e., beliefs) increases, then attitudes toward the object of those beliefs will also increase". (Ajzen and Sexton 1999, p. 118). Eastin (2002) provides supporting evidence in a laboratory experiment, in which he identifies subjects with high levels of...
