“…Less ambiguous results might be achieved by employing objective indices of behavioral malfunctioning that cut across traditional nosological categories. Objective indices of behavior may be able to confirm the hypothesis, suggested by a series of studies, that patients who exhibit low levels of suggestibility are typically ''deteriorated," "preoccupied," "out of contact," or "rigidly unrealistic" (Gale & Herman, 1956;Heath et al, 1960;Polak et al, 1964). In the present study, psychopatho-logical behaviors were measured by means of an objective instrument (Psychotic Inpatient Profile) that has satisfactory reliability and validity (Lorr & Vestre, 1968).…”

“…Nonstandardized procedures. Most studies evaluating suggestibility in hospitalized psychotics used either the Hull (1933) postural sway test or the 1931 Davis-Husband Scale (Bartlett, 1936(Bartlett, , 1944Friedman & Keup, 1963;Gale & Herman, 195 6;Heath, Hoaken, & Sainz, 1960;Polak, Mountain, & Emde, 1964;Webb & Nesmith, 1964;Whitman, 1961;Williams, 1932;Wilson, Gormen, & Cole, 1949). However, the postural sway test is an inadequate measure of overall suggestibility (Webb, 1946), and the Davis-Husband Scale is a crude and arbitrary measure of "hypnotic" suggestibility that fails to specify scoring criteria (Barber, 1969, p. 33).…”

“…Duration of illness. Investigators who reported that psychotic patients exhibit low levels of response to suggestions usually tested patients who had been hospitalized for many years (Barber et al, 1964;Heath et al, 1960;Lavoie, Sabourin, & Langlois, 1973). On the other hand, investigators who found relatively high levels of suggestibility tested newly hospitalized patients (Kramer & Brennan, 1964;Polak et al, 1964).…”

Previous studies pertaining to suggestibility in psychotic patients have yielded inconsistent and contradictory results. To resolve these contradictions, the present study assessed the objective and subjective responses of 77 hospitalized schizophrenics on the Barber Suggestibility Scale. Nineteen additional variables were also recorded, including patients' chronological age, marital status, education, duration of hospitalization, psychopathological behavior, and cooperativeness. Results indicated that these variables together accounted for 44% and 48% of the variance in subjective and objective scores on the Barber scale, respectively. The results also indicated that a relatively small number of these variables accounted for most of the predicted variance in both measures of suggestibility. These findings suggest that inconsistencies in the results of previous studies were due, in part, to the fact that the patient populations in those studies were not comparable.Studies assessing suggestibility 1 in hospitalized psychotics have yielded contradictory results; some investigations found very low levels of suggestibility, whereas others found somewhat high levels. For instance, Copeland and Kitching (1937) reported that "without exception" psychotic patients were not responsive to suggestions, and Gill and Brenman (1959) considered those few schizophrenics who were good subjects to be marked exceptions to the rule. Contradictory findings were reported by at least three sets of investigators: Gordon (1973), Brennan (1964), andWebb andNesmith (1964) found that psychotic patients were at least as suggestible as normals. There appear to be at least five variables, discussed below, related to the contradictory results.

“…While the differences in length of hospitalization in the three groups used in this study were not significant, if the figures on length of hospitalization for the Hypnotized group are compared to the analogous data in Kramer and Brennan (1964), then some support is lent to the statement made by Heath et al (1960) that there appears to be some relationship between hypnotizability and chronicity.…”
