Abstract
The L-M Fergus Falls Behavior Rating Sheet (L-M FFBRS) is a standardized assessment tool, originally developed in 1951, designed for the objective measurement of the behavior of psychiatric patients. This instrument is particularly valuable in clinical settings where patients exhibit behavioral difficulties such as mutism, unintelligible speech, hyperactivity, or severe withdrawal, making them challenging to assess using traditional psychometric measures. The scale is structured to be comprehensive yet efficient, assessing eleven distinct areas of patient functioning based on observation by ward staff. Its key design criteria include ease of use by untrained raters, quantifiability, and sensitivity to changes in patient behavior over time.

Purpose
The primary purpose of the L-M FFBRS is to provide a quick, objective, and quantifiable method for evaluating the observable behavior of patients in mental hospital settings. It was specifically created to overcome the limitations of subjective staff reports and complex psychological tests that often fail to capture the behavior of severely disturbed or non-verbal patients.
The scale serves multiple functions, including monitoring patient progress, assessing responsiveness to treatment interventions (such as insulin or electroshock therapy), and providing data suitable for research purposes. Its design prioritizes ease of use, ensuring that it can be effectively administered by ward aides and staff who may not possess specialized training in standardized assessment tools.
Construct
The L-M FFBRS measures the construct of observable, adaptive, and maladaptive behaviors demonstrated by institutionalized psychiatric patients within their daily ward environment. Rather than focusing on internal psychological states or subjective symptoms, the scale quantifies actions and reactions across key domains of daily living and social interaction.
The scale is divided into eleven specific behavioral categories, covering critical areas such as work participation, self-care, social responsiveness to peers and staff, and psychomotor activity. The resulting scores provide a comprehensive profile of the patient’s functional status and level of cooperation.
Validity
The structured format and clear behavioral descriptions employed by the L-M FFBRS lend themselves to high face validity. The scale items directly reflect behaviors that clinicians and ward staff consider essential indicators of patient functioning and recovery within a hospital setting. The scale’s ability to provide objective measures of behavior suggests that it successfully measures the intended construct for use in institutionalized populations, particularly those difficult to evaluate by standard methods.
Reliability
The L-M FFBRS demonstrated high inter-rater reliability during its initial development. This is a crucial feature for any behavior rating scale, as it indicates that the assessment results are consistent regardless of which staff member (e.g., nurse or aide) completes the observation. The descriptive checklist format minimizes subjective interpretation, ensuring that the quantifiable results are reliable measures of the observed behavior.
Factor Analysis
The source documentation does not provide details regarding formal factor analysis conducted on the L-M FFBRS. Given its early development date (1951), the scale structure relies on rational item grouping based on clinical relevance, dividing the assessment into eleven empirically relevant behavioral domains.
Instrument
Test Type: Observer-rated behavior rating scale.
Format: Primarily a checklist format using five descriptive options per behavioral category, supplemented by several open-ended questions requiring narrative input regarding specific patient activities or physical ailments.
Language Available: English (Original).
Population Group: Psychiatric patients (Institutionalized).
Age Group: Adults (Implied by the context of mental hospital residency and treatments like ECT/Insulin therapy).
Population Details: Specifically targets patients whose conditions (e.g., mutism, extreme negativity, hyperactivity, or unintelligible speech) render them unsuitable for self-report or traditional interview-based psychometric testing.
Test Methodology: Observational rating by nursing staff or psychiatric aides over a specified period, focusing on the patient’s most frequent behavior during that time frame. The scale assesses eleven aspects of behavior.
Keywords
Psychological instruments, Mental health assessment, Clinical observation, Ward behavior, Inter-rater consistency, Functional status.

Items of the L-M Fergus Falls Behavior Rating Sheet
IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.
Instructions: At the top of the Behavior Rating Sheet fill in as much informasion as can be found on the ward. Below you will find eleven different groups of descriptions of a par?cular type of behavior. Place a check (X) by the descrip?on that comes closest to telling how this par?cular pa?ent has behaved for _________________. If the pa?ent’s behavior has changed in this period, then check the descripsion which tells how the parent has behaved most of the ?me. If the parent’s behavior is evenly divided, then check two descrip?ons (or more, if necessary). Look at each group separately, do not try to give an overall impression at any 1me because, as you well know, a certain parent may be a very good worker but he may not speak at all. If you feel that you don’t know enough about a certain bit of behavior (example, you haven’t seen the parent eat) then leave that part out, it is far more important to have true descripsuons than to have many descriptions. There will be other descrip?ons that you will have to leave out. (Examples: if parent isn’t ge Wng insulin or electric treatments, you There are blanks under some of the groups. Fill them in as per instruc?ons.
