Relationship of obsessive—compulsive symptomatology to anxiety, depression and schizotypy in a clinical population

Abstract

The relationship of obsessive-compulsive symptomatology to anxiety disorders, mood disorders and schizophrenia continues to be controversial. In a sample of 117 psychiatric out-patients, we examined the relationship of obsessive-compulsive symptomatology to indices of anxiety, depression and schizotypy. The relationship between obsessive-compulsive symptomatology and schizotypy was found to be significantly higher than that between obsessive-compulsive symptoms and either anxiety or depression. These findings are consistent with recent studies suggesting that there are similar cognitive deficits associated with obsessive-compulsive symptoms and schizotypy and that obsessive-compulsive disorders may be more closely aligned to the schizophrenic constellation of disorders than to anxiety disorders.

“…Low correlation values of some items in the scale can be explained by the situation existing in scale development studies. In addition to this, t values of three items (16,23,24) were not statistically significant. In the first study for adaptation to Turkish, it was found that items 16 and 24 worked while item 23 did not work (7).…”

“…As a result, non-significant t values may be the result of reverse coded items. The Cronbach alpha internal consistency coefficients of the scale in different cultures with different samples were calculated as 0.84 (21), 0.81 (22), 0.87 (23). The reliability coefficients of the scale are close to these values but a little bit lower in the Turkish sample.…”

“…All the items in the scale include true false questions. There are 7 reverse-scored (7,12,13,16,18,23,24) and 23 straight-scored items in the scale. Hence, high scores of the scale indicate high magical thinking and low scores indicate low magical thinking.…”

“…The instrument has adequate levels of internal consistency, test-retest reliability and convergent validity (Feske & Chamless, 2000;Macdonald & de Silva, 1999). Two-factor analytic studies have suggested four component scales: (1) checking behaviour; (2) impaired control over mental activities; (3) contamination concerns, and (4) fear of losing motor control (Norman et al, 1996;Sanavio, 1988).…”

“…The scale was originally designed as a measure of psychosis proneness. It has demonstrated construct validity as a measure of schizotypy (Chapman & Chapman, 1985;Chapman, Chapman, & Miller, 1982), and adequate internal consistency (Eckblad & Chapman, 1983;Norman, Davies, Malla, Cortese, & Nicholson, 1996).…”
