Measures the degree to which incarcerated individuals attribute jail experiences and outcomes to internal personal control versus external institutional forces.
Scale Development & Technical Details
Scale Overview
The Prison Locus of Control Scale (PLOC) was developed by Anna Cutlip (2002). It is designed to measure Locus of Control in Correctional Environments. The scale is intended for use with Incarcerated individuals / Inmates.
Scale Structure
This instrument consists of 35 items organized into 2 factors/subscales: Internal Locus of Control, External Locus of Control.
| Factor / Subscale | Items | N |
|---|---|---|
| Internal Locus of Control | 1,12,13,15,16,17,18,19,21,22,23,24,28,31,32,34 | 16 |
| External Locus of Control | 2,3,4,5,6,7,8,9,10,11,14,20,25,26,27,29,30,33,35 | 19 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Agree, 2 = 2, 3 = 3, 4 = 4, 5 = 5, 6 = 6, 7 = 7, 8 = 8, 9 = 9, 10 = Disagree.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Not specified in source text.
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.
