Scale Overview
The Self-Perception Profile for Children – SPPC was developed by Susan Harter (1985). It is designed to measure Self-concept and domain-specific self-perceptions. The scale is intended for use with Children (ages 8 to 15 / grades 3 to 8).
Scale Structure
This instrument consists of 36 items organized into 6 factors/subscales: Scholastic Competence, Social Acceptance, Athletic Competence, Physical Appearance, Behavioral Conduct, Global Self-Worth.

Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Really True for Me (Negative side), 2 = Sort of True for Me (Negative side), 3 = Sort of True for Me (Positive side), 4 = Really True for Me (Positive side).
The scale includes 18 reverse-scored items to reduce acquiescence bias.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 1 to 4. Interpretation guidelines:
- Low perceived competence/self-worth: 1 – 2
- Medium perceived competence/self-worth: 2 – 3
- High perceived competence/self-worth: 3 – 4
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of 0.71 to 0.86 (Cronbach's alpha across subscales).
Administration
The scale is self-administered and typically takes approximately 15 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
