Background/Description
There are 45 items that make up the BPCS, which is an instrument that is meant to assess personal control. There are three aspects of personal control that are measured by the device. On the actual measure, the following items are shown for each of the three subscales:
- General external control (F1) is a measurement that determines the degree to which a person feels that their results are self-made (internally developed) or are caused by fate or other people (externally developed).
- The Exaggerated Control Dimension (F2) analyses an exaggerated and irrational conviction in one’s own ability to exert control over one’s own life.
- The God-mediated dimension (F3) is a measurement of the notion that the idea that God can be implicated in the accomplishment of results is measured. This scale differentiates between those who feel they have no influence over their results and those who believe that they have power over their fates via God.
Administration, Scoring and Interpretation
- Explain the procedure: Briefly explain the purpose of the BPCS and assure participants that their responses are anonymous and confidential.
- Distribute materials: Pass out the questionnaires and answer sheets to participants.
- Read instructions: Read the instructions on the questionnaire aloud for all participants to ensure clarity.
- Answer questions: Briefly answer any questions participants may have regarding the instructions or items.
- Allow sufficient time: Provide participants with ample time to complete the questionnaire without feeling rushed.
- Collect materials: Once everyone has finished, collect the completed questionnaires and answer sheets.
Reliability and Validity
In terms of reliability, the data exhibits very good to outstanding internal consistency, with alphas of.85 (F1),.88 (F2), and.97 (F3) respectively. A test-retest correlation of.81 (F1), together with test-retest correlations of.85 (F2) and.93 (F3), indicates that the measure is relatively stable.
Excellent construct validity, showing correlations in the predicted directions with other measures such as the Internal-External Locus of Control and the Taylor Manifest Anxiety Scale. Validity: Excellent construct validity.
