Part I: Construct Development and Scale Creation Choose a construct you would like to measure. Self-esteem. Create an operational definition of your construct using at least three peer-reviewed journal articles as references. Select and list five items used to sample the domain. Select the method of scaling appropriate for the domain. Justify why you selected the scaling method you did. Format the items into an instrument with which you would query respondents. Justify whether this is an interview or self-report instrument. Part II: Analysis and Justification Write a 1,400- to 1,750-word analysis of how you developed your instrument. Describe how you would norm this instrument and which reliability measures you would use. Discuss how many people you would give it to. Describe the characteristics that your respondents would have. Explain to whom the instrument would be generalized. Describe how you would establish validity. Describe the methods you used for item selection. Discuss whether or not cut-off scores would be established. Explain how item selection will be evaluated. I need homework on the above question but I only need three questions answered: 1. Select the method of scaling appropriate for the domain. 2. Describe how you would establish validity. 3. Describe the methods you used for item selection.

Selected method of scaling appropriate for the domain of self-esteem

For measuring self-esteem, the most appropriate scaling method is the Likert scale. The Likert scale is widely used in psychological assessments because it allows respondents to express the intensity of their feelings or attitudes toward items related to self-esteem. It provides ordinal data that can be treated as interval data in many analyses, which is advantageous for statistical purposes. The Likert scale typically consists of a range of response options, such as from "Strongly Disagree" to "Strongly Agree," which captures the degree of agreement or disagreement with statements reflecting self-esteem levels. Its simplicity and respondents’ familiarity with this format make it suitable for self-report measures of psychological constructs like self-esteem, facilitating ease of administration and interpretation.

The choice of the Likert scale is justified based on several factors. First, self-esteem is a subjective and internal construct; thus, capturing varying degrees of internal attitudes is essential. Second, the Likert scale enhances reliability because it provides multiple response options that can encompass subtle differences in respondents’ perceptions. Third, it allows for straightforward quantification and statistical analysis, making it suitable for psychometric evaluation and norming. Finally, previous research in self-esteem measurement, such as Rosenberg’s Self-Esteem Scale (RSES), successfully employs Likert-type responses, validating its appropriateness for this domain.

Establishing validity of the self-esteem instrument

Establishing validity is crucial to ensure that the instrument accurately measures the construct of self-esteem. Several forms of validity will be considered and established during the development process.

Content validity will be initially established through a comprehensive review of the literature and consultations with experts in psychology and self-esteem research. This involves ensuring that the items adequately cover the domain of self-esteem, including aspects such as self-worth, self-acceptance, and personal value. The five items selected will be scrutinized by experts for relevance and comprehensiveness.

Construct validity will be assessed through convergent and divergent validity tests. Convergent validity involves correlating the new instrument with established self-esteem measures, such as Rosenberg’s Self-Esteem Scale, expecting moderate to high correlations. Divergent validity will be established by demonstrating low correlations with unrelated constructs, such as extraversion or neuroticism. Factor analysis, specifically exploratory factor analysis (EFA), will be employed to verify that the items load onto a single self-esteem factor, confirming construct coherence.

Criterion-related validity will be examined by correlating the instrument scores with external criteria known to relate to self-esteem, such as psychological well-being or academic performance. Establishing criterion validity involves demonstrating that scores predict relevant outcomes, aligning with theoretical expectations.

Finally, pilot testing the instrument with a small sample will allow for assessing item performance and refining items based on participants’ feedback and statistical analysis, such as item-total correlations and response variability.

Methods used for item selection

Item selection began with a comprehensive review of existing literature and established self-esteem scales like Rosenberg’s Self-Esteem Scale, to identify core themes and effective survey items. An initial pool of approximately ten items was generated, focusing on core aspects of self-esteem, such as self-worth, confidence, and acceptance. Each item was evaluated for clarity, relevance, and cultural appropriateness. Items that were ambiguous or socially undesirable were discarded or revised.

Next, the items underwent expert review by psychologists specializing in self-esteem research, who assessed face validity and content coverage. Items with high relevance and clarity were retained. Following expert review, preliminary testing with a small sample allowed for statistical analysis—in particular, item-total correlations to identify items that strongly correlated with the overall trait measure and response variability, ensuring each item contributed meaningfully to the construct.

Items demonstrating poor performance, such as low correlation with total scores or limited response variability, were eliminated. The final selection comprised five items that best represented the domain of self-esteem, balancing brevity and comprehensiveness. These items were then formatted into a Likert scale with response options from "Strongly Disagree" to "Strongly Agree." This iterative process ensured the instrument’s clarity, content validity, and internal consistency, vital for reliable and valid measurement of self-esteem.
