This study examined headaches and temporomandibular dysfunction in 79 undergraduate psychology students based on their responses to a symptom questionnaire developed for the study. Participants were differentiated into groups showing symptoms of headache, temporomandibular dysfunction (TMD), both headache and TMD, or few or no symptoms. Psychological variables (depression, anxiety, perceived stress, health locus of control, type-A, and hostility) and electromyograms (EMG) were compared. Laboratory stress (anagram task) was used while recording EMG. The data were analyzed using a discriminate function analysis which showed that a combination of psychological variables discriminates between groups with 69% accuracy. The results and questionnaire developed may be used to better understand the etiology of the different conditions, and to aid in prevention, diagnosis, and treatment.
