LOCUS OF CONTROL ORIENTATION AND LEVEL - Drake University

Low positive correlations with appr~pfiate internal, powerful others, and chance
(1, P & C) scale items indicated construct validity. Predictive validity was
established with correlations in the predicted direction of the MHLC scales with
the health status (Wallston et al., 1978).
Protection of Human Rights
Permission to conduct the study was obtained from the Drake University
Human Subjects Research Review Committee (HSRRC) and the hospital's
Institutional Review Committee (IRC) (see Appendix E for letter of permission
from IRC). Permission was received from Wallston to use the MHLC scales
(see Appendix F for permission to use MHLC scales). The subjects' rights to
freedom from harm, informed consent, and privacy were protected. Potential
subjects were sent a consent letter, the MHLC scales, and a self-addressed
stamped envelope. The eonsent letter informed the potential subjects of the
purpose of the study, the person's role in the study, potential benefits, and
directions as to how to complete the materials (see Appendix G for consent
letter). The letter included a statement that completion and return of the
materials indicated consent to participate and allowed the researcher permission
to review the patient record for pain scores and demographic data. This study
required no intervention or manipulation of the normal course of therapy and
therefore no threat of harm for the participants. The only possible threat to
participants was an invasion of privacy. Participants were assured that
confidentiality was to be maintained by identifying persons only by their
hospital 1.D. number throughout the study. The subjects were informed that
any data published as a result of this study would be reported as '4ZgrePte data-
