Abstract
The Parental Tolerance Scale (PTS), initially developed by Butler, Brewin, and Forsythe in 1986, is a brief, specialized psychological scale designed to quantify the attitudes and emotional responses of parents toward their child’s nocturnal enuresis (bedwetting). The instrument measures the degree to which a parent expresses empathy, understanding, and acceptance (tolerance) versus frustration, disappointment, and punitive actions (intolerance) regarding the child’s wetting episodes. The PTS is valuable in clinical settings for assessing the psychosocial impact of enuresis and identifying parental attitudes that may interfere with effective treatment.

Purpose
The primary purpose of the Parental Tolerance Scale is to provide a standardized, quantifiable measure of parental attitudes toward a child experiencing nocturnal enuresis. This assessment is crucial because parental reactions—whether supportive or punitive—significantly influence the child’s self-esteem, psychological distress, and overall response to treatment for bedwetting.
The scale aids clinicians and researchers in mapping the psychosocial environment surrounding the child’s condition. By identifying patterns of low tolerance or high punitive behavior, the PTS helps pinpoint areas where parental education or counseling may be necessary to maximize the potential for successful treatment outcomes and minimize the emotional sequelae of enuresis on the child.
Construct
The PTS measures the construct of Parental Tolerance, which encompasses both cognitive attributions and affective responses related to enuresis. High tolerance is characterized by the attribution of bedwetting to uncontrollable factors (e.g., medical or developmental immaturity) and associated feelings of empathy and support. Low tolerance, conversely, is characterized by the attribution of bedwetting to controllable factors (e.g., laziness or deliberate defiance) and associated feelings of frustration, disappointment, and the use of punitive measures.
The scale effectively distinguishes two core dimensions of parental response: an empathic, tolerant dimension focused on support, and a punitive, intolerant dimension focused on blame and punishment. This dual structure allows for a nuanced assessment of parental attributions regarding the etiology and controllability of the child’s wetting.
Validity
The construct validity of the PTS has been supported through its consistent factor structure and its ability to correlate logically with related psychological measures. Studies, such as those published in the journal Behaviour Research and Therapy, have shown that the PTS successfully discriminates between parents who adopt supportive coping strategies and those who resort to blame or punishment.
Further validation evidence comes from the scale’s ability to predict clinical outcomes. Parental intolerance, as measured by the PTS, has been shown to correlate negatively with treatment compliance and positively with psychological distress reported by the child. This predictive power highlights its utility as a clinical screening tool.
Reliability
The reliability of the Parental Tolerance Scale, particularly its internal consistency, has been established in multiple research contexts. Measures of internal reliability (such as Cronbach’s alpha) typically demonstrate acceptable to good coefficients, confirming that the items within the scale consistently measure the underlying construct of tolerance or intolerance.
While the overall scale demonstrates good consistency, the reliability may be more robust when the scale is scored using its empirically derived subscales (Tolerance and Intolerance factors), ensuring that specific dimensions of parental reaction are measured accurately. The stability of the scale over time (test-retest reliability) is generally assumed to be reasonable, reflecting the stability of core parental attitudes during the treatment phase.
Factor Analysis
Empirical analyses of the PTS generally support a two-factor model, reflecting the bipolar nature of the construct being measured. These factors are:
- Tolerance/Empathy Factor: This factor groups items reflecting understanding, pity, acceptance, and a belief that the child cannot control the wetting. High scores on this factor indicate a supportive parental environment.
- Intolerance/Punitive Factor: This factor groups items reflecting frustration, disappointment, attributing the wetting to a lack of effort or maturity, and the use of punishment. High scores on this factor indicate a potentially stressful or punitive home environment related to the enuresis.
This distinct factor structure allows researchers to measure specific aspects of parental response rather than just a global score, offering a deeper insight into the psychological mechanisms at play.
Instrument
Test Type: Parent Self-Report Inventory
Format: 16 Dichotomous items (Yes/No response format)
Language Available: English (Original)
Population Group: Parents, primarily Mothers, of children diagnosed with nocturnal enuresis.
Age Group: Parents of children typically aged 5 years and older who experience persistent bedwetting.
Population Details: The scale was initially validated using samples of mothers whose children were attending specialist enuresis clinics. It focuses on the primary caregiver who manages the domestic and emotional consequences of the child’s condition.
Test Methodology: The parent responds to 16 statements by indicating either “Yes” or “No.” Scoring involves assigning points to tolerant responses and reverse-scoring intolerant responses to calculate overall tolerance scores or separate factor scores.
