Relationship of internal-external control and United States suicide rates, 1966-1973.
The annual variations in scores obtained on the Rotter Internal-External (I-E) control scale by United States college students between the years 1966 and 1973 were related to the concomitant annual variations in suicide rates for the total United States population and for eight separate age groups. The I-E scores increased substantially during this time period and were correlated positively with the concomitantly increasing suicide rates among relatively young persons (in and below the 35-44 year age group). However, the suicide rates among older persons generally decreased during this time period and thus were correlated negatively with the I-E scores. These results suggest that perception of internal-external control did not change among older persons as they did among younger persons, perhaps because older persons might be less susceptible to the cultural influences that affect the perceived control of younger persons. Results of this and earlier research suggest that cultural characteristics that foster high perceptions of external control also foster suicidal behavior and suggest the value of attempts to convey perceptions of internal control to psychotherapy clients.
