Parental Locus of Control Scale – PLOC
Measures parental locus of control across five dimensions to assess parents' perceived control over their parenting outcomes and child's behavior.
Scale Development & Technical Details
Scale Overview
The Parental Locus of Control Scale – PLOC was developed by Campis, L., Lyman, R., & Prentis-Dunn, S. (1986). It is designed to measure Parental Locus of Control. The scale is intended for use with Parents.
Scale Structure
This instrument consists of 47 items organized into 5 factors/subscales: Parental Efficacy, Parental Responsibility, Child Control of Parents’ Life, Parental Belief in Fate/Chance, Parental Control of Child’s Behavior.
| Factor / Subscale | Items | N |
|---|---|---|
| Parental Efficacy | 1,2,3,4,5,6,7,8,9,10 | 10 |
| Parental Responsibility | 11,12,13,14,15,16,17,18,19,20 | 10 |
| Child Control of Parents' Life | 21,22,23,24,25,26,27 | 7 |
| Parental Belief in Fate/Chance | 28,29,30,31,32,33,34,35,36,37 | 10 |
| Parental Control of Child's Behavior | 38,39,40,41,42,43,44,45,46,47 | 10 |
Response Format
Respondents rate each item using a 5-point Likert scale (1 = Strongly Disagree to 5 = Strongly Agree).
The scale includes 20 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 47 to 235. Interpretation guidelines:
- Internal Parental Locus of Control: 47 – 141
- External Parental Locus of Control: 142 – 235
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Alpha coefficients range from .65 to .77 for subscales, and .84 for the total scale..
Administration
The scale is self-administered and typically takes approximately 10 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
