Indecision Scale

Abstract

The Indecision Scale, developed by Holland, John L. and Nichols, Robert C. in 1964, is a psychological instrument designed to quantify personal attributes that influence a student’s capacity for vocational decision-making prior to college entry. The instrument consists of 15 items and was initially derived from an extensive item analysis of 273 activities, hobbies, school subjects, and sports favored by a large sample of high aptitude students known as National Merit Finalists. Subsequent validation involved a separate sample of 217 male students, and the psychometric evaluation included calculating internal consistency using the Kuder-Richardson formula 20.

Purpose

The primary purpose of the Indecision Scale is to measure specific personal and psychological attributes that contribute directly to a student’s ability or inability to make effective vocational decisions. This assessment is particularly relevant for students transitioning from high school to higher education or career paths.

The scale was intended as a tool for researchers and counselors working with high-aptitude student populations, helping to identify underlying factors related to decisiveness or hesitation in career planning before entering college.

Construct

The central construct measured by the scale is Vocational Decision-Making, specifically focusing on the personal characteristics that inhibit or facilitate this process, which manifest as indecision.

The development process aimed to isolate traits that distinguish students who have clearly defined vocational goals from those who remain undecided, thereby operationalizing indecision as a measurable psychological attribute.

Validity

The validation process primarily focused on aspects of construct validity. Researchers examined the correlations between scores on the Indecision Scale and external criteria, specifically self-ratings related to leadership and future life goals.

In the sample of male participants, self-ratings of leadership ability showed a statistically significant positive correlation with scale scores (r = .22, p < .01). For female participants, this correlation was also positive and significant (r = .16, p < .05). Furthermore, the life goal of aspiring to be a community leader was positively correlated with the scale for both boys (r = .16, p < .05) and girls (r = .14, p < .05).

Reliability

Internal consistency, or homogeneity, was assessed using the Kuder-Richardson formula 20 (KR-20). The resulting coefficients suggested limited internal consistency, particularly for female participants.

The reliability coefficient calculated for boys was .60, while the coefficient for girls was notably lower at .40. The authors noted that these lower-than-ideal coefficients confirmed clinical impressions regarding the heterogeneity of the attributes contributing to indecision among the student population studied.

Factor Analysis

The original documentation regarding the development and validation of the Indecision Scale does not indicate that a formal factor analysis was performed to determine the underlying dimensional structure of the 15 items.
