Abstract
The Self-Control Rating Scale (SCRS) is a widely recognized psychometric instrument designed to assess the behavioral and cognitive manifestations of self-control in children. Developed by Philip C. Kendall and Lori E. Wilcox in 1979, the SCRS provides a standardized method for parents or teachers to rate a child’s ability to delay gratification, inhibit impulsive actions, and persist in tasks. The scale is particularly valuable in clinical and educational settings for identifying deficits related to impulsivity and attention regulation.
Comprising 33 items, the SCRS measures various facets of self-regulation, including adherence to rules, patience, persistence, and the ability to manage emotional excitement. Its robust psychometric properties, including high internal consistency (Cronbach’s alpha = 0.98), have solidified its use in research concerning child development and behavioral interventions.

Purpose
The primary purpose of the SCRS is the standardized assessment of a child’s capacity for self-control, defined operationally through observable behaviors indicative of impulse regulation and sustained attention. It was developed to provide researchers and clinicians with a reliable measure to evaluate treatment effects in cognitive-behavioral interventions targeting behavioral problems such as attention-deficit issues or conduct disorders.
The scale focuses specifically on behaviors related to waiting, following instructions, regulating motor activity, and maintaining focus on tasks. By quantifying these behaviors on a 7-point scale, the SCRS allows for a clear comparison of an individual child’s self-control capacity against normative data, aiding in both diagnosis and longitudinal progress tracking.
Construct
The SCRS measures the psychological construct of self-control, which encompasses both cognitive and behavioral components. This construct is understood as the capacity to override prepotent responses (impulsivity) and to regulate attention, emotion, and behavior in the service of achieving long-term goals. The items reflect behaviors associated with three key domains: impulsivity (e.g., interrupting, acting without thinking), persistence (e.g., sticking to tasks, working toward long-range goals), and delay of gratification (e.g., waiting patiently, postponing immediate rewards).
The underlying theoretical framework often relates to cognitive-behavioral models, where self-control is viewed as a learned skill set that can be improved through structured intervention. The scale attempts to capture the observable output of these internal regulatory mechanisms as perceived by an external rater (parent or teacher).
Validity
While the source content does not explicitly list specific validity coefficients, the development process described in the foundational literature (Kendall & Wilcox, 1979) established strong content validity by deriving items from clinical observations and expert consensus regarding self-control deficits in children. Subsequent research has supported the scale’s construct validity through expected correlations with measures of related constructs, such as teacher ratings of hyperactivity, attention problems, and academic achievement.
The structure of the scale is designed to reflect the multi-faceted nature of self-regulation, and modifications, such as the scale developed by Lennings (1991) for delinquent populations, further demonstrated criterion validity by showing that SCRS scores could effectively differentiate between clinical and non-clinical groups, confirming its utility in distinguishing children with significant self-regulatory challenges.
Reliability
The SCRS demonstrates exceptional levels of reliability, confirming its stability and internal consistency. The internal reliability, measured using Cronbach’s alpha, was reported as highly satisfactory at 0.98. This extremely high value indicates that the 33 items consistently measure the same underlying construct, suggesting strong homogeneity within the scale.
Additionally, the scale exhibits robust test-retest reliability. For a sample (n=24) taken from the present group, reliability assessed over a 3-4 week interval was strong, yielding a coefficient of 0.84. This suggests that the ratings obtained using the SCRS are stable over short periods, making it suitable for reliable baseline assessment and tracking changes following intervention.
Factor Analysis
Initial psychometric evaluations of the SCRS suggested a strong underlying unidimensional factor related to general self-control or impulse inhibition. However, further exploratory and confirmatory factor analyses conducted in subsequent studies (e.g., Kendall et al., 1981) have sometimes suggested a two-factor structure. These factors typically divide the items into categories reflecting overt behavioral impulsivity (e.g., interrupting, physical restlessness) and cognitive self-regulation (e.g., planning, persistence, working toward goals).
Despite potential sub-factors, the scale is most commonly utilized and scored as a single, global measure of self-control capacity, given the high intercorrelations among the items and the very high overall internal consistency reported.
Instrument
Test Type: Behavioral Rating Scale (Parent or Teacher Report)
Format: 33 items scored on a 7-point Likert scale (1 = never, 7 = always).
Language Available: Primarily English (Original).
Population Group: Children and adolescents.
Age Group: Typically utilized with elementary school-age children (often 6 to 12 years old).
Population Details: Developed using both non-referred and clinically referred children, and frequently applied in research concerning externalizing disorders.
Test Methodology: Raters (parents or teachers) assess the frequency of specific self-control behaviors exhibited by the child over a defined period, scoring on a continuum from 1 (never) to 7 (always).
