Belgian Norms for the Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility

Belgian norms of the Waterloo-Stanford Group C Scale of Hypnotic Susceptibility (WSGC) are presented. A French translation of the WSGC was administered to 150 Belgium college students between October and December 2009. Belgium has 2 main linguistic groups, Dutch and French speakers. The present translation was conceived for all French-speaking populations. Score distribution, item analysis, and reliability of the WSGC are presented and compared to the normative sample of the WSGC. The results were also compared with 2 North American norms (University of Connecticut and Seton Hall University) and a Portuguese (translated) norm. The findings show that normative data from the French (Belgium) sample are in line with the reference samples. The only significant difference was the lower proportion of participants scoring within the high range of hypnotic suggestibility on the WSGC.     

Portuguese norms for the Waterloo-Stanford Group C (WSGC) scale of hypnotic susceptibility

Portuguese norms for the Waterloo-Stanford Group C (WSGC) scale of hypnotic susceptibility are presented. A Portuguese translation of this scale was given to 625 Portuguese college students. Score distribution, item analysis, and reliability of the WSGC are presented and compared to three North American samples. The findings show that normative data from the Portuguese sample are congruent with the reference samples. The only significant difference obtained was a lower proportion of participants scoring within the high range of hypnotic suggestibility on the WSGC.

The Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility: Normative and Comparative Data

The Waterloo-Stanford Group C (WSGC) hypnotic susceptibility scale was developed as a substitute for the individually administered Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). A first investigation with WSGC reports normative data on 259 subjects, and the results indicate that it is comparable in most important respects to the norms of SHSS:C. A second investigation directly compared WSGC and SHSS:C in a counterbalanced design on 65 subjects, and the two scales correlated .85. It is argued that, when used as a follow-up to the Harvard Group Scale of Hypnotic Susceptibility, Form A, WSGC provides a valid criterion of hypnotic ability.     

Finnish norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A

Finnish norms of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) are presented. The aggregate sample of 285 subjects consisted of 3 groups (n = 129, n = 116, and n = 40) that were tested during 1996 and 1997. Comparisons are made with the original normative American sample, an Australian sample, and 3 translated adaptations of HGSHS:A in Danish, German, and Spanish. In the Finnish sample, Items 2 (eye closure), 11 (posthypnotic suggestion), and 12 (amnesia) received high passing percentage in comparison with the reference data, but generally the Finnish normative data were congruent with these index studies.     

French Norms for the Harvard Group Scale of Hypnotic Susceptibility,Form A

The authors present French norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). They administered an adapted translation of Shor and Orne’s original text (1962) to a group of 126 paid volunteers. Participants also rated their own responses following our translation of Kihlstrom’s Scale of Involuntariness (2006). Item pass rates, score distributions, and reliability were calculated and compared with several other reference samples. Analyses show that the present French norms are congruous with the reference samples. Interestingly, the passing rate for some items drops significantly if “entirely voluntary” responses (as identified by Kihlstrom’s scale) are scored as “fail.” Copies of the translated scales and response booklet are available online.     

Book review

To overcome problems with previous psychometric approaches to hypnosis scales, the authors applied full-information factor analysis, based on multidimensional item-response theory (IRT), to a 39-year sample of 11,517 records of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). They also performed a comparable analysis on the standardization sample of the Waterloo-Stanford Group C Scale (WSGC). The HGSHS:A emerges as two-factored, whereas the WSGC more closely approaches unidimensionality. The HGSHS:A factor structure and means show very little change over 4 decades. However, IRT-based item analysis on the HGSHS:A indicates that problems such as “pseudoguessing” on 2 items limit the quality of the item set. The authors propose alternative substantive interpretations of the traits that may underlie the two-factor structure.

Italian norms for the harvard group scale of hypnotic susceptibility,form a

Norms for an Italian translation of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) by Shor and Orne (1962) are presented. Subjects recruited from 1986 to 1989 were pooled, resulting in a sample of 376 participants (297 women and 79 men). The normative data were generally congruent with earlier normative studies in score distribution, item difficulty levels, and reliability. Women had significantly higher hypnotizability scores and item pass rates than men. The reliability scores of the Italian adaptation of the HGSHS:A were the same as a previously reported Danish sample and higher than a German sample, but lower than those of the Australian, Canadian, and original American samples. These results suggest that the Italian version of the HGSHS:A is an efficient tool for initial hypnotizability screening in an Italian context.

A sociological analysis of the extent and influence of professional socialization on the development of a nursing identity among nursing students at two universities in Brisbane, Australia

Professions make extraordinary demands on its practitioners Professionals are required to master substantive theory and technical skills They also develop their own unique subcultures, demanding specific normative standards from their members, which are symbolized by professional ethical codes In the health professions, ethical codes include strong altruistic elements Professiona normative standards are learnt on a formal level (for example, at a university) and informal level (during the process of professional socialization and contact with the peer group, as well as informal sanctions) The transformation process of a novice to a professional is essentially an acculturation process during which the values, norms and symbols of the profession are internalized Acculturation can be so strong that it may cause personality transformation, which the French refer to as 'deformation professionelle', usually displayed by stereotypes, which are almost always exemplified by members of professions as ideal professionals, those who have internalized the profession's culture completely The question is, what is the extent of normative standards and professional characteristics that nursing students are exposed to during professional socialization, and to what extent are these standards and characteristics internalized so that a nursing 'deformation professionelle' develops9 A reliable Likert-type measurement scale was developed to measure this phenomenon One of the most important findings of this study was that students at both universities are highly professionally socialized     

Preliminary study to evaluate the validity of the mini-mental state examination in a normal population in Turkey

Although the Mini-Mental State Examination (MMSE) is widely used in clinical practice, normative scores for a healthy population have not been documented in Turkey. The aim in this study was to validate the MMSE in a healthy population and to provide normal scores. Internal construct validity of the Turkish version of MMSE among a preliminary sample of 406 normal people was assessed by Rasch unidimensional measurement model. Scores of the normal sample varied according to age and education but not according to sex. The data derived from this sample showed poor fit to the Rasch model (mean item fit, -2.082, SD 3.022). Only four of 11 items met model expectations. There was also differential item functioning by education and age for most items. Thus the internal construct validity of the Turkish MMSE in a normative sample could not be demonstrated by Rasch analysis. The scale failed modern psychometric criteria for scalability. We would therefore suggest other large normative MMSE data sets to be tested in terms of internal construct validity. If these findings are replicated, the validity of MMSE norms and their consequent use in clinical practice should be reconsidered.     

Pilot normative database for the Wolf Motor Function Test

OBJECTIVE: To gather initial data on the Wolf Motor Function Test (WMFT) from able-bodied participants. DESIGN: Cross-sectional cohort study. SETTING: Clinical research laboratory. PARTICIPANTS: A convenience sample of 51 healthy able-bodied, right-hand dominant, adult participants, between the ages of 40 and 79 years. INTERVENTION: One-time administration of the WMFT. MAIN OUTCOME MEASURE: The WMFT. RESULTS: Mean data are presented for all timed and strength tasks. For timed tasks on the WMFT, there were no significant differences among subjects for hand or sex nor was there a hand by sex interaction. Men were significantly stronger than women on the 2 strength tasks, however. CONCLUSIONS: We provide preliminary normative data for the WMFT. More data are needed to produce precise estimates of norms and to explore relations among sex, age, and hand dominance.     

The Stanford Hypnotic Susceptibility Scale, Form C: normative data of a Dutch student sample

Norms for the Dutch language version of the Standford Hypnotic Susceptibility Scale, Form C (SHSS:C; Weitzenhoffer & Hilgard, 1962) are presented. These norms are based upon a sample of 135 students at a Dutch university. Generally, the psychometric properties of the Dutch version of the SHSS:C are similar to other language versions. However, the mean score was somewhat lower than that found in the original norming studies at Stanford University.     

The y-state-an hypnotic variant

Since the recent development of the Stanford Hypnotic Susceptibility Scales, researchers have been provided a means of investigating crucial problems in the area of hypnosis. This study investigates the applicability of the reported norms to a population which differs from the normative sample. “True volunteer” dental students were found to score well above the “volunteer” normative sample due mainly to the reduced percentages of low hypnotic susceptibility Ss. The effects of schooling, volunteering, and implications concerning the relationship between personality and hypnotic susceptibility in the volunteer sample are discussed.

Motor development of Native American children on the Peabody Developmental Motor Scales.

OBJECTIVE: Native American children have not been widely represented in the normative samples of standardized tests assessing motor development. This study investigated the cultural relevance of the Peabody Developmental Motor Scales (PDMS) in 2-year-old Native American children who are typically developing. METHOD: The PDMS was administered to a sample of 44 Pueblo children who were 24 months through 35 months of age and typically developing. Each child's family also completed a parent questionnaire addressing the child's development and family demographics. Participant scores were compared with those of the normative sample. RESULTS: The sample scored significantly lower than the normative sample (p < or = .001) on the Fine Motor Scale, and, when gender was taken into consideration, all but the older girls (30 months-35 months of age) had significantly lower scores. All but the younger girls (24 months-29 months of age) scored within the normal range on the Gross Motor Scale. CONCLUSION: Our results with this small sample suggest that caution be used when comparing motor performance (especially fine motor abilities) of 2-year-old Native American children against the PDMS normative data.     

Cross-country validity of the Alberta Infant Motor Scale using a Brazilian sample

BackgroundPrevious validity studies of the Alberta Infant Motor Scale (AIMS), using raw scores and percentile curves for group comparisons, showed that infants in Brazil achieved gross motor milestones at later ages. Validity of the AIMS norms were later reassessed using a logistic regression model that placed the AIMS items on an age scale.ObjectivesOur study examined the validity of the AIMS norms for Brazilian infants using the recommended method for calculating and comparing item locations.MethodsData from 732 Brazilian infants (2009–11), 3 days to 18 months old, were compared to the AIMS normative sample (n = 2202). Logistic regression placed the AIMS items of both samples on age scales representing the age at which 50% of infants passed an item and compared the two datasets. Pearson correlation coefficient tested the association across samples.Results47 of the 58 AIMS items met the criterion for stable regression to calculate item locations of the Brazilian dataset. Based on the age when 50% of the infants passed a criterion, most of the items from the Brazilian sample (n = 28) differed by two weeks or less compared to the Canadian normative sample.ConclusionThe sequence and age for the emergence of AIMS items were similar between the Brazilian and Canadian samples. Canadian norms are appropriate for clinical decisions and research with Brazilian infants.     

Swedish norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A

This article examines the norms for a Swedish adaptation of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) (Shor & Orne, 1962). In total, 291 subjects (199 females and 92 males) participated in the study. Comparisons are made between the Swedish sample and reference samples, which include English versions of the HGSHS:A from the United States and Australia, as well as 5 translated versions from Italy, Finland, Denmark, Spain, and Germany. In the Swedish sample, females scored significantly higher than males. Generally, however, the normative data from the Swedish sample are congruent with the reference samples and therefore can be used as a tool for initial screening of hypnotic susceptibility in Sweden.
