Blame Assignment Scale

Abstract

The Blame Assignment Scale (BAS), developed by Laxer, Robert M. in 1964, is a psychological instrument designed to quantify the degree and nature of blame assignment in both clinical and non-clinical populations. The scale was meticulously constructed through a multi-stage process involving the collection of typical patient statements, subsequent rating by experts using a 7-step scale, and the application of paired comparisons methodology to establish numerical values for 22 selected statements. During administration, individuals—specifically psychiatric patients—are tasked with selecting three out of twenty-three total cards that most accurately reflect the perceived reasons for their current psychological condition.

Purpose

The primary function of the Blame Assignment Scale is to provide a standardized measurement of how individuals attribute causality for their current state or circumstances. The scale is specifically formulated to assess patterns of blame assignment across a diverse spectrum, including both individuals diagnosed as psychiatric patients and those within the normal population.

This assessment is crucial for understanding underlying psychological mechanisms, particularly in clinical settings where excessive self-blame or externalization of responsibility can be symptomatic of conditions like depression. By quantifying these attributions, researchers and clinicians can better categorize the psychological orientation of the respondent.

Construct

The core psychological construct measured by this instrument is Blame Assignment. This construct refers to the cognitive process by which an individual identifies and attributes responsibility or fault for a negative outcome, event, or personal condition. The scale aims to differentiate between various targets of blame, such as self-blame, external blame, or fate/circumstance.

The development methodology utilized paired comparisons to ensure that the numerical values assigned to each statement accurately reflect the relative intensity or degree of blame being expressed, thereby establishing an interval-level measure for this complex attributional process.

Validity

Currently, specific details regarding the validity of the Blame Assignment Scale are not explicitly reported in the available source documentation. Information concerning content validity, criterion validity (concurrent or predictive), or construct validity was not provided at the time of publication.

While the initial development stages involved expert rating and rigorous selection of items through paired comparisons—a process that inherently contributes to content and face validity—formal psychometric validation studies are required to establish the scale’s effectiveness in measuring the intended construct reliably and accurately across different populations.

Reliability

Similar to validity data, concrete evidence regarding the reliability of the Blame Assignment Scale is currently unavailable. No internal consistency measures (such as Cronbach’s alpha), test-retest reliability coefficients, or inter-rater reliability statistics were reported by Laxer (1964) in the primary source article.

The absence of reliability data makes it challenging to ascertain the consistency and stability of the scale’s measurements over time or across different administrations. Future psychometrics research is necessary to confirm the robustness of the instrument for clinical or research use.

Factor Analysis

No formal factor analysis was reported for the Blame Assignment Scale in the foundational literature. Factor analysis, a statistical technique used in test development, would typically be employed to determine if the 22 statements load onto distinct underlying dimensions or factors of blame assignment (e.g., internal vs. external blame).

Without factor analytic evidence, the scale is generally treated as a unidimensional measure of overall blame attribution, although the selection of disparate statements suggests potential multidimensionality that remains empirically unexplored.

Instrument

Test Type: Rating Scale; Attitudinal Assessment

Format: The scale consists of 22 statements, each assigned a predetermined numerical value based on the results of the initial paired comparisons phase. Administration typically involves the participant selecting 3 out of 23 cards (22 scale items plus one additional card, presumably for neutral or unknown attribution) that best explain their condition. The methodology is paper-based.

Language Available: English

Population Group: Human (Male and Female)

Age Group: Not explicitly specified, but context suggests adult populations (psychiatric patients and normal adults).

Population Details: The scale was intended for use with individuals categorized as “self-blaming normals and abnormals,” highlighting its utility in assessing attributional styles across clinical severity.

Test Methodology: The scale was developed in four distinct stages:

• Collecting typical patient statements from psychiatrists and psychologists.
• Rating these statements on a 7-step scale by expert judges.
• Selecting 22 optimized statements for application of the paired comparisons technique.
• Calculating the final numerical values for these 22 statements to establish the metric properties of the scale.
