Positive Childhood Experiences (PCEs) scale

The PCEs provides a single total score where scores range from 0-7. The PCEs uses a Likert response format but only response options of “Most of the time” or “All of the time” are indicative of a positive experience being present (a score of 1) whereas all other response options represent an absence of the positive experience (a score of 0). The total score represents the sum of all positive childhood experiences endorsed, providing a comprehensive measure of protective factors that research links to enhanced resilience and better mental health outcomes even in the presence of childhood adversity.

For clinical interpretation, PCEs scores are categorised into three qualitative descriptors:

1. Low (0-2 PCEs): Indicates fewer protective childhood experiences than average. Research suggests individuals in this range may benefit from building additional positive experiences and supportive relationships in current life. Each new positive experience can contribute to improved resilience and wellbeing.
2. Moderate (3-5 PCEs): Represents a moderate level of protective childhood experiences. Individuals in this range had access to some positive experiences that likely provide a foundation for resilience. Building on these existing strengths may further enhance wellbeing and coping capacity.
3. High (6-7 PCEs): Indicates a robust collection of protective childhood experiences. Research shows that individuals with high PCEs demonstrate significant resilience and typically report better mental health and social-emotional outcomes, even when faced with adversity.

These descriptors offer clinically meaningful categorisations that facilitate interpretation and communication of results.

Upon first administration a plot is displayed showing the PCEs total score with qualitative descriptors presented in the background for ease of translation. If administered on multiple occasions, an additional plot is presented showing the total score over time.

The seven items in the PCEs scale were adapted from four subscales included in the Child and Youth Resilience Measure-28 (CYRM-28): (1) four items from the Psychological Caregiving subscale; (2) one from the Education subscale; (3) one from the Culture subscale; and (4) one from the Peer Support subscale (Bethell et al., 2019).

Principal components factor analysis confirmed that the PCEs scale has a unidimensional structure with a single eigenvalue greater than 1.0 (2.95) that explained 42.2% of variance. Factor loadings across the seven items ranged from 0.57 (“felt safe/home”) to 0.72 (“family stood by/difficult times”), indicating good factor structure (Bethell et al., 2019). The scale demonstrates good internal consistency with a Cronbach’s alpha of 0.77.

Construct validity of the PCEs scale is supported by its demonstrated associations with mental health outcomes. In the original study, Bethell et al. (2019) found that the adjusted odds of depression and/or poor mental health (D/PMH) were 72% lower (OR, 0.28; 95% CI, 0.21-0.39) for adults reporting high levels of PCEs (6-7) versus those reporting low levels (0-2). The adjusted odds were 50% lower (OR, 0.50; 95% CI, 0.36-0.69) for those reporting moderate PCEs (3-5 PCEs).

The scale also demonstrates predictive validity for relational health outcomes. Bethell et al. (2019) found that the adjusted odds that adults reported “always” on the adult-reported social and emotional support (ARSES) variable were 3.53 times (95% CI, 2.60-4.80) greater for adults with high versus low PCEs. These relationships between PCEs and adult outcomes remained stable across all levels of adverse childhood experiences (ACEs), providing strong evidence for the scale’s validity in diverse contexts of childhood adversity.

Cross-cultural validity is supported by findings from the Wisconsin Behavioral Risk Factor Survey (Bethell et al., 2019), which demonstrated that PCEs were associated with positive outcomes across diverse racial, ethnic, and socioeconomic groups. 

Three distinct qualitative descriptors are presented for scores on the PCEs, providing clinically meaningful thresholds that reliably differentiate between outcome groups: 

• Low scores (0-2 PCEs) indicate limited protective childhood experiences and are associated with increased vulnerability to mental health concerns, particularly in the context of childhood adversity. In the Bethell et al. (2019) study, approximately 48.2% of adults with low PCEs met criteria for depression and/or poor mental health, and only 33.0% reported consistently receiving needed social and emotional support. 
• Moderate scores (3-5 PCEs) represent an intermediate level of protective experiences; individuals in this range have access to some positive childhood experiences but may benefit from additional support or resources. About 25.1% of individuals with moderate PCEs met criteria for depression/poor mental health, and 43.6% reported always receiving needed support. 
• High scores (6-7 PCEs) indicate robust protective childhood experiences and are associated with significant resilience even in the face of adversity. Only 12.6% of adults with high PCEs reported depression/poor mental health, and 67.9% reported always receiving needed social and emotional support. 

These categories demonstrate a clear dose-response relationship between PCEs and adult outcomes (Bethell et al., 2019).
