“…For example, several studies have found that those with an external locus of control, more than those with an internal locus of control, report problems with depression, anxiety, hypochondriasis, phobic avoidance, and socially prescribed perfectionism (Benassi, Sweeney, & Dufour, 1988;Hewitt & Flett, 1991;Hutner & Locke, 1984;Katerndahl, 1991;Scott & Severance, 1975). Studies have also shown that those with an internal, more than an external, health locus of control seek health care knowledge, use specific information about their disease and treatment, engage in more preventive health behaviors, and feel less vulnerable to health problems (Bundek, Marks, & Richardson, 1993;Jex, 1991;Kirscht, 1972;Slenker, Price, & O'Connell, 1985).…”
